Description

The present disclosure relates to a user interface and locking function for positioning multiple components within the body.

The statements in this section merely provide background information regarding this disclosure and may not constitute prior art.

Inserting and manipulating thin elements inside living organisms or other objects allows for the analysis, diagnosis, and treatment of ever-increasing types of bodies or objects with minimally invasive techniques. As two examples, endoscopic imaging and catheterization procedures have enabled the assessment and treatment of numerous internal injuries without invasive surgery.

Electrosurgical procedures also provide minimally invasive therapy by selectively applying electrical current to selected tissue. An electrosurgical procedure involves extending one or more electrodes through an opening or small incision to a desired location within the body, and then applying a radio frequency (“RF”) current to the electrodes at that location.

The following description describes various embodiments of a user interface for positioning electrodes for electrosurgical instruments, as well as systems including such user interfaces and methods of using them, by way of example only and without limitation. .. As described in detail below, the electrosurgical procedure positions the first and second electrodes in close proximity to a reference point to which an electrical procedure, such as a procedure with ablation, is applied. For specific examples, user interfaces and methods of their use can be used to ablate and / or coagulate tissues, remove damage, and perform other medical procedures inside the lungs.

It will be appreciated that various embodiments of the user interface described herein can help simplify the process of electrode positioning and holding of the electrodes in place. As described below, various embodiments of the user interface allow the selection of electrodes in place by a combination of pressing of the release device and sliding of the lever, rotation and sliding of the housing, or sliding of the lever and rotation of the housing. Achieve proper positioning and locking.

With reference to FIG. 1, a system 100 for treating tissue at a reference point in the patient's anatomical region (not shown in FIG. 1) is provided. System 100 may optionally be a bipolar or unipolar radio frequency (RF) system for treating the patient's tissue. Specifically, System 100 is a percutaneous and / or endoscopic (including bronchoscopic) surgical procedure, such as partial and / or complete ablation of cancerous and / or non-cancerous organ lesions. During the procedure, it can be used for soft tissue coagulation and / or ablation. As further described, the tissue is treated by positioning one or more electrodes in close proximity to the tissue to be treated and by passing an electric current through the tissue at a reference point.

In some embodiments, the system 100 is an electrosurgical device such as a user interface 101, an electrosurgical radio frequency (RF) generator acting as a switchable current source 114, an infusion pump 116, and an unlimited bronchoscope 118. Or including equipment. It will be appreciated that the electrosurgical device or instrument may also include an endoscope or any other electrosurgical device desired for a particular application. The bronchoscope 118 may be configured to receive the user interface 101 at port 148, allowing the user interface 101 to operate the electrodes at a reference point via the bronchoscope 118.

The user interface 101 electrically communicates with a switchable current source 114 through the conductor 130. In some embodiments, the conductor 130 is connected to the outlet 131 when the system is operated in bipolar mode. The conductor 130 may be coupled to the outlet 131 using an electrical connector 134 that is configured to electrically engage the outlet 131. In some other embodiments, the system 100 can be operated in unipolar mode when optionally an adapter (not shown in FIG. 1) is used to connect the conductor 130 to the secondary outlet 133. .. The user interface 101 is further connected to the injection pump 116 by a tube 132 that facilitates the flow of a liquid, such as saline, from the injection pump 116 to the user interface 101.

The switchable current source 114 can be operated by the use of a foot-operated unit 120 electrically connected to the switchable current source 114. The foot-operated unit 120 tells the switchable current source 114 to apply a current to the electrodes (s) (discussed below) to cut and / or ablate the tissue, and to the generator 114. Includes a pedal 124 that directs a low current to be applied to the electrodes (s) to coagulate the tissue.

In various embodiments, the bronchoscope 118 includes an insertion tube 119 that allows insertion of the sheath 103 into the body (not shown). The distal end 105 of the sheath 103 is delivered to a location near the tissue to be treated at the reference point. The sheath 103 includes an electrode (not shown) and transports it to a desired treatment position. The positioning of the distal end 105 of the sheath 103 and the distal end of the electrode (not shown in FIG. 1) can be controlled by the user interface 101 received by the bronchoscope 118 at port 148.

With reference to FIGS. 2-6, the distal end of the component is positioned relative to reference point 201 using various embodiments of the user interface. The reference point 201 may be a point within the target tissue 202, for example, a lesion or any part of the tissue to be treated in the body. As provided by way of example only and without limitation, all exemplary embodiments of the user interface described below will include each of the described embodiments as described with reference to FIGS. 2-6. The components can be positioned as described further with reference. The description of FIGS. 2 to 6 is provided as a reference for explaining the operation of various embodiments of the user interface.

In certain embodiments, the secondary electrode 211 is slidably received within the primary electrode 207 and the primary electrode 207 is slidably received within the sheath 203. In certain embodiments, the primary electrode 207 and the secondary electrode 211 move with the sheath 203 until the user interface is manipulated to move the primary electrode 207 and / or the secondary electrode 211 separately. This means that the electrodes 207 and 211 move at the same time as the sheath 203 and through the same distance. As will be described later, in some cases, the secondary electrode 211 may also move with the primary electrode 209 while both electrodes move independently of the sheath 103. The components included in the other components are represented by broken lines in FIGS. 2 to 6.

With reference to FIG. 2, the sheath 203, the primary electrode 207, and the secondary electrode 211 are shown to be positioned initially with respect to the reference point 201 at or near the target tissue 202. More specifically, FIG. 2 shows the insertion tube 119 and the bronchoscope 118 of FIG. 1 before being accurately moved to a desired position by manipulating a user interface (not shown) described later. The components that can be positioned at the time of insertion of the sheath 203 through the intubation in the bronchoscope are shown.

The distal end 205 of the sheath 203 is positioned in close proximity to the target tissue 202. The primary electrode 207 is slidably received within the sheath 203 with the distal end 209 of the primary electrode 207 at or near the distal end 205 of the sheath. Specifically, FIG. 2 shows, for example, the distal end 209 of the primary electrode 207 positioned in front of the distal end 205 of the sheath 203. Next, the secondary electrode 211 is slidably received in the primary electrode 207 with the distal end 213 of the secondary electrode 211 positioned only within the distal end 209 of the primary electrode 207.

Referring to FIG. 3, the sheath 203, the primary electrode 207, and the secondary electrode 211 are shown to be positioned once the sheath 203 approaches the reference point 201. In contrast to FIG. 2, in FIG. 3, the distal end 205 of the sheath 203 is closer to the reference point 201 at the edge of the target tissue 202. As in FIG. 2, the primary electrode 207 and the secondary electrode 211 did not move separately due to the operation of the user interface (not shown), so that the primary electrode 207 and the secondary electrode 211 move the sheath 203. Moved with. Therefore, at the deployment position closer to the reference point 201, the distal end 209 of the primary electrode 207 remains positioned in front of the distal end 205 of the sheath 203. Similarly, the distal end 213 of the secondary electrode 211 remains positioned only within the distal end 209 of the primary electrode 207. As further described with reference to embodiments of the sheath lock that can be part of the user interface or can be used with the user interface, when the distal end 205 of the sheath 203 is moved to the desired position, the sheath 203 is moved. Can be locked in place.

Referring to FIG. 4, the sheath 203, the primary electrode 207, and the secondary electrode 211 are positioned so that the primary electrode 207 is positioned when it extends from the sheath 203 to the reference point 201 and into the target tissue 202. It is shown. In certain embodiments, the secondary electrode 211 will have the secondary electrode 211 as the primary electrode, unless the user interface (not shown) is manipulated to disengage the movement of the secondary electrode 211 from the movement of the primary electrode 207. It moves together with the primary electrode 207 while moving in the same direction and at the same distance as the 207. Thus, as shown in FIG. 4, when the primary electrode 207 extends beyond the distal end 105 of the sheath 103, the secondary electrode 211 moves with the primary electrode 207. As shown in FIG. 4, the distal end 209 of the primary electrode 207 extends towards the reference point 201 and beyond the distal end 205 of the sheath 203. The distal end 213 of the secondary electrode 211 remains positioned only within the distal end 209 of the primary electrode 207. In certain embodiments, the primary electrode 207 allows the distal end 209 to penetrate tissue such as the target tissue 202 so that the distal end 209 of the primary electrode 207 reaches a desired position. It is in the form of a needle configured so that the secondary electrode 211 can be placed at a desired point.

As described further below, when the distal end 205 of the sheath 203 is in the desired position and locked in place, the user interface embodiment allows the primary electrode 207 to move independently of the sheath 103. The primary electrode 207 can be unlocked. Further, as will be described later, in the embodiment of the user interface, the movement of the secondary electrode 211 is caused by the movement of the secondary electrode 207 so that the distal end 213 of the secondary electrode 211 moves together with the distal end 209 of the primary electrode 207. It may remain locked with movement. Further, as will be further described later, embodiments of the user interface allow one or both of the primary electrode 207 and the secondary electrode 211 to be fixed in place, i.e., to stay in place, resulting in the electrode 207 and One or both of 211 are fixed in their current position. Thus, for example, while the position of the primary electrode 207 can be fixed, the secondary electrode 211 can move independently of the primary electrode 207, or the position of the secondary electrode 211 can be fixed, while the primary electrode 207 can be fixed. It can move independently of the secondary electrode 211. Also, both electrodes 207 and 211 can be fixed in place when the procedure is performed by applying an electric current using an electrosurgical instrument, such as that shown in system 100 of FIG.

With reference to FIG. 5, the sheath 203, the primary electrode 207, and the secondary electrode 211 are shown to be positioned when the secondary electrode 211 extends from the primary electrode 207. The distal end 213 of the secondary electrode 211 is deployed at a position beyond the reference point 201 and from the primary electrode 207 to the opposite side of the target tissue 202. In certain embodiments, the secondary electrode 211 is configured as a coiled wire that is received in the primary electrode 207 in a linear shape. When the user interface is manipulated to extend the secondary electrode 211 independently of the primary electrode 207, the secondary electrode 211 becomes spiral. As a result, the distal end 213 of the secondary electrode 211 spirals into tissue such as the target tissue 202. The spiral progression of the distal end 213 of the secondary electrode 211 can aid in fixing the position of the distal end 213 of the secondary electrode 211 during the procedure. FIG. 5 also shows insulator 215 along the length of the secondary electrode 211, which stops the short circuit at the distal end 213 of the secondary electrode 211. When a current is applied to the proximal ends (not shown) of the primary electrode 207 and the secondary electrode 211, the current is applied to the distal end 209 of the primary electrode 207 and the uninsulated distal end 213 of the secondary electrode 211. The insulator 215 electrically insulates the secondary electrode 211 from the primary electrode 207 so that it can flow only between and.

Referring to FIG. 6, the sheath 303, the primary electrode 207, and the secondary electrode 511 are partially retracted from the target tissue 202 and into the sheath 503, with the primary electrode 207 partially retracted away from the reference point 201. It is shown to be positioned when it is stored. As mentioned above, the needle shape of the primary electrode 207 assists in positioning the distal end 213 of the secondary electrode 211 at the desired position. However, when the distal end 213 of the secondary electrode 211 is placed in that position, the distal end 213 of the secondary electrode 211 may be energized to treat the target tissue 202 near the reference point 201. It may be desired to move the distal end 209 of the primary electrode 207 away from the reference point 201 in order to create the desired gap between the and the distal end 209 of the primary electrode 207. As described further below, when the distal end 213 of the secondary electrode 211 is fixed in the desired position, an embodiment of the user interface (not shown in FIG. 6) provides the partial storage shown in FIG. To make this possible, the primary electrode 207 is unlocked and allowed to move independently of the secondary electrode 211. Once partially retracted, embodiments of the user interface also allow the primary electrode 207 to be locked in place.

With reference to FIGS. 7A and 7B, the instrument 700 is a broncho used to perform a diagnostic or therapeutic task by extending the sheath or catheter into the body (not shown in FIGS. 7A and 7B). Includes an exemplary user interface 701 accepted at port 748 of an electrosurgical instrument 718, such as a mirror or another minimally invasive device. In the instrument 700 of FIG. 7A, the user interface 701 is configured to move the sheath actuator 704 and the sheath 103 to a desired position to position the distal end 105 of the sheath 103 with respect to the reference point 201. 706 is included. In some embodiments, the sheath actuator 704 may be a slidable mechanism that includes a slidable sleeve 712 that is received within the collar 714. The slidable sleeve 712 can be locked in place on the collar 714 by the sheath lock 706. The sheath lock 706 mechanically engages with a spring-loaded lock pin, thumbscrew, or slidable sleeve 712 to place the slidable sleeve 712 and then the sheath 703 in place at the desired location. It may be another mechanism configured to be fixed.

In some embodiments, the sheath actuator 704 may be part of the user interface 701. For example, in the user interface 701 of FIG. 7A, the slidable sleeve 712 is fixably engaged with the interface housing 710 at the distal end 716 of the interface housing 710. The collar 714 may then engage port 748 on the electrosurgical instrument 718, where the movement of the slidable sleeve 712 within the collar 714 controls the movement of the sheath 103. In some other embodiments, the sheath actuator 704 may be, for example, part of an electrosurgical instrument 718. The collar 714 may be fixedly joined to the port 748. The slidable sleeve 712 may be associated with the port 748 and engaged with the distal end 716 of the interface housing 710. In another embodiment, the slidable sleeve 712 may be fixably joined to the distal end 716 of the interface housing 710 and receptively engages a collar 714 fixably attached to port 748. It may be configured to do so. Any of these embodiments of the sheath actuator 704 may facilitate the movement of the sheath 103 as described below.

In various embodiments, the user interface 701 has a primary electrode 207 slidably received within the sheath 103 and a distal end 209 of the primary electrode 207 positioned in front of the distal end 105 of the sheath 103. It is mechanically coupled. The user interface 701 also has a secondary electrode 211 slidably received within the primary electrode 207 and a distal end 213 of the secondary electrode 211 positioned only within the distal end 209 of the primary electrode 207. It is mechanically connected. An embodiment of the user interface 701 is such that both the primary electrode 207 and the secondary electrode 211 move with the sheath 103 as the sheath moves, as described with reference to FIG. The next electrode 211 may be configured to be fixed to the sheath 103.

With reference to FIGS. 8A and 8B, the operation of the sheath actuator 704 shows an example of how the sheath 103 can be unlocked and moved to the aforementioned position with reference to FIG. In the configuration shown in FIGS. 8A and 8B, the sheath actuator 704 is manipulated to allow the sheath 103 to move closer to the reference point 201 and the target tissue 202 over a distance of 819. Specifically, when the sheath lock 706 of the sheath actuator 704 is operated to enable the movement of the slidable sleeve 712 in the collar 714, the interface housing 710 moves a distance of 819 and is based on the sheath 103. Move the same distance for 819 minutes toward point 702. Once the sheath 103 reaches the desired position, the slidable sleeve 712 can be locked in place on the collar 714 by the sheath lock 706. As will be further described later, the embodiment of the user interface 701 maintains the positions of the primary electrode 207 and the secondary electrode 211 with respect to the sheath 103 when the sheath 103 is moved by using the sheath actuator 704. Therefore, the distal end 209 of the primary electrode 207 and the distal end 213 of the secondary electrode 211 also move toward the reference point 201 by a distance 219.

With reference to FIG. 9, the enlarged external view shows the exemplary sheath actuator 704 and sheath lock 706 in more detail. The sheath actuator 704 is fixably attached to a connector 920 configured to engage a port (not shown in FIG. 9) of an electrosurgical instrument (not shown in FIG. 9) such as a bronchoscope. Includes a slidable sleeve 712. In the embodiment of FIG. 9, the sheath lock 706 is fixedly attached to the interface housing 710 in order to move the sheath (not shown in FIG. 9) described above with reference to FIGS. 7 and 8. A thumbscrew that may be loosened to allow movement. After manipulating the interface housing 710 to slide the collar 714 against the slidable sleeve 712 to move the sheath to the desired position, the sheath lock 706 is used to secure the position of the sheath. , Re-engaged by turning the thumbscrew, etc.

With reference to FIG. 10, the schematic cut-out view of the sheath actuator 704 shows the internal operation of the sheath actuator 704 of FIG. As mentioned above, the sheath actuator 704 includes a slidable sleeve 712 that is fixably attached to the connector 920. In some embodiments, the sheath lock 706 can be anchored to the interface housing 710 to move the sheath 103, as well as the primary and secondary electrodes 211 received in the sheath 103. A thumbscrew that may be loosened to allow movement of the attached collar 714. In order to move the sheath 103 to the desired position, the interface housing 710 is operated to slide the collar 714 with respect to the slidable sleeve 712, and then the sheath lock 706 is turned to slide the position of the collar 714. The position of the sheath 103 is fixed by fixing it to a possible sleeve 712.

Referring to FIG. 11, in some embodiments, the exemplary user interface 1101 is used to position the sheath 1003, the primary electrode, and the secondary electrode with respect to a reference point (not shown in FIG. 11). User interface 1101 includes components that move parallel to or laterally to axis 1121 or rotate around curve 1123 around axis 1121, as described below. The user interface 1101 enters the collar 1114 fixably attached to the interface housing 1110 when the connector 1120 and the sheath 103 are released by the sheath lock 1106 as described above with reference to FIGS. 9 and 10. Includes a sheath actuator 1104 that includes a moving slidable sleeve 1112. User interface 1101 also accepts lead 1122, which provides an electrical connection between the electrodes and a switchable current source (not shown in FIG. 11) as described above with reference to FIG. The user interface 1101, as well as other embodiments of the user interface described throughout this description, also accept salt water sources (not shown) that can pass through the sheath to facilitate the application of electrosurgical procedures. Although not explicitly shown in subsequent depictions of other exemplary embodiments of the user interface described with reference to FIGS. 35-5, similar leads can be used to switch with the electrodes. It will be appreciated that it can provide an electrical connection to and from a current source.

The exemplary user interface 1101 shown in FIG. 11 includes several user controls whose operations and effects are described in more detail in the following figures. The primary release device 1130 is configured to unlock the movement of a primary electrode (not shown) that extends from the lower 1124 of the housing 1110 and moves through the operation of the primary actuator 1132 that extends from the upper 1126 of the housing 1110. ing. The primary actuator 1132 is mechanically coupled to a primary electrode (not shown in FIG. 11) so that when the primary actuator 1132 moves relative to the housing 1110, the primary electrode becomes a reference point (similarly in FIG. 11). (Not shown). The depth gauge 1190 on the housing 1110 includes an indicator 1192 that indicates the insertion depth of the primary electrode beyond the end of the sheath (not shown).

The secondary release device 1150 is integrated with the secondary actuator 1152 arranged along the upper side 1126 of the housing, and is configured to unlock and control the movement of the secondary electrodes, respectively. The secondary actuator 1152 is fixably coupled to the secondary grip portion 1153 extending from the lower 1124 of the housing 1110. The secondary actuator 1152 is a secondary electrode (not shown) such that when the secondary actuator 1152 moves relative to the housing 1110, the secondary electrode moves relative to a reference point (not shown). Is mechanically coupled to.

The actuator interlock 1140, positioned along the lower 1124 of the housing 1110, limits the movement of the secondary electrode with respect to the primary electrode, blocks the use of the primary release device 1130, and the secondary electrode, as described below. (Not shown) can be separated from the primary electrode. As shown below, when both the primary actuator 1132 and the secondary actuator 1152 move simultaneously, the actuator interlock 1140 moves with the primary actuator 1132 and the secondary actuator. As will be further described later, in the primary release device 1130, the actuator interlock 1140, and the secondary release device 1150, the simultaneous and independent selective movement of the electrodes facilitates the placement of the distal ends of the electrodes in the body. Make it possible.

Referring to FIGS. 12A and 12B, in some embodiments, the user interface 1101 has an initial deployment configuration when the sheath 103 is deployed near the reference point 201. As described with reference to FIGS. 7A-10, the sheath actuator 1104 and the sheath lock 1106 are pre-engaged and the distal end 105 of the sheath 103 is near the reference point 201 as shown in the inset. Position it in the desired position. As described above, the primary electrode 207 is received in the sheath 103 with the distal end 209 of the primary electrode 207 initially positioned in front of the distal end 105 of the sheath 103. The secondary electrode 211 is received in the primary electrode 207 with the distal end 213 of the secondary electrode 211 positioned in front of the distal end 209 of the primary electrode 207.

With reference to FIGS. 13A and 13B, in some embodiments of user interface 1101, the primary release device 1130 is engaged to allow the primary electrode 207 to move. Specifically, the release of the primary release device 1130 is achieved by pressing the primary release device 1130 toward the housing 1110 of the user interface in the direction 1331. The operation of the primary release device 1130 does not cause the sheath 103 or the electrode 207 or 211 to move relative to the reference point 201, as shown in the inset of FIG. 12B, but only allows the primary electrode 207 to move, which will be further described later. As such, the secondary electrode 211 may or may not be moved.

With reference to FIGS. 14A and 14B, user interface 1101 is shown after the primary actuator 1132 has traveled a distance of 1433. After the primary actuator 1132. To. Four actions are generated by the movement of the primary actuator 1132. First, the movement of the primary actuator 1132 extends beyond the distal end 105 of the sheath 103 and into the target tissue 202, thereby extending the primary electrode 207, as shown in the insertion of FIG. 14B. The distal end 209 of 207 is positioned close to the reference point 201. Second, the secondary electrode 211 moves with the primary electrode 207 with the distal end 213 of the secondary electrode 211 continuously positioned in front of the distal end 209 of the secondary electrode 207. Third, the coincident movement of the primary electrode 207 and the secondary electrode 211 is reflected in the movement of the actuator interlock 1140, the secondary release device 1150, the secondary actuator 1152, and the secondary grip portion 1153 at the same distance 1433. .. The primary actuator 1132 and the secondary actuator 1152 are mechanically coupled to allow consistent movement of the primary electrode 207 and the secondary electrode 211 as described below. Fourth, the indicator 1192 of the depth gauge 1190 is also mechanically coupled to the primary actuator 1132. Therefore, the distance 1433 that the primary actuator 1132 and the primary electrode 207 travel is indicated by the indicator 1192 on the depth gauge 1190.

Referring to FIG. 15, the primary actuator 1132 and the primary release device 1130 are described with reference to FIGS. 11-14B with the primary release device 1130 in the locked position shown in FIGS. 12A and 14A. Can be used in the embodiments of. The primary actuator 1132 is attached to a primary electrode slider 1533 that is mechanically coupled to the primary electrode 207 in order to move the primary electrode 207 as described above with reference to FIGS. 2-6 and 12-14. It is mechanically connected. When the primary release device 1130 is in the locked position, the locking member 1534 extending through the inside of the primary actuator 1132 is urged by an urging member such as a spring 1535 to accommodate the user interface housings of FIGS. 11-14. The internal locking rack 1538 pushes the lock pin 1536 into the starting notch 1537 (not shown in FIG. 15). The lock pin 1536 forcibly engages the starting notch 1537 to prevent the movement of the primary actuator 1132 and thus also the movement of the primary electrode slider 1533 and the primary electrode 207. Therefore, the primary release device 1130 at the lock position shown in FIG. 15 locks the primary electrode slider 1530 and the primary electrode 207 to their current positions.

With reference to FIG. 16, the operation of the primary actuator 1132 and the primary release device 1130 is shown in a state in which the primary release device 1130 is engaged to allow the primary actuator 1132 to move. When a force is applied to the primary release device 1130 to move the primary actuator 1132 in direction 1631, the primary release device 1130 moves the lock member 1534 in direction 1631, compresses the spring 1535 and sets the lock pin 1536 to the start notch 1537. Allows movement of the primary actuator 1132. In other words, the pressing of the primary release device 1130 releases the lock pin 1536 from the starting notch 1537 of the locking rack 1538, allowing the primary actuator 1132 to move the primary electrode slider 1533.

Referring to FIG. 17, the operation of the primary actuator 1132 in moving the primary electrode slider 1533 and the primary electrode 207 is shown while allowing the primary actuator 1132 to move while the primary release device 1130 is engaged. There is. As shown with reference to FIG. 16, allowing the primary actuator 1132 to release the lock pin 1536 from the starting notch 1537 causes the locking member 1534 to compress the spring 1535, the primary actuator 1132, and thus. Allows the primary electrode slider 1533 and the primary electrode 207 to move in the direction 1731 with respect to the housing 1110. The force applied to the primary release device 1130 continues to compress the spring 1535 into the locking member 1534, thus allowing the locking pin 1536 to move relative to the locking rack 1538. Here, the lock pin 1536 can engage the selected notch 1739 in the locking rack 1538 when released at the position shown in FIG. It should be noted that when the primary actuator 1132 moves relative to the housing 1110, the primary release device 1130 moves with the primary actuator 1132. Therefore, only the starting notch 1537, the locking rack 1538, and the housing 1110 remain in the same position in the embodiment of FIG.

Upon release of the primary release device 1130, the pressure previously applied by the locking member 1534 on the spring 1535 is released. As a result, the spring 1535 pressurizes against the locking member 1534 and then engages the locking pin 1536 with the selected notch 1739 in the locking rack 1538. Next, similar to the configuration shown in FIG. 15, the primary electrode slider 1530 and the primary electrode 207 are then locked in a new position with respect to the housing 1110 and also the primary electrode inside the body (also not shown in FIG. 17). The distal end of 207 (not shown in FIG. 15) is also moved.

Referring to FIGS. 18A and 18B, in some embodiments, the primary electrode 207 is referenced with the distal end 209 just before the secondary release device 1150 is engaged to unlock the movement of the secondary electrode 211. It is deployed near point 201 and locked in place as shown in FIG. 14B. The secondary release device 1150 is integrated with the secondary actuator 1152. Specifically, the secondary release device 1150 partially downwards toward the interface housing 1110 in order to disengage the secondary actuator 1152 from the primary electrode slider (not shown in FIG. 18A). It constitutes the end of a secondary actuator 1152 that can be pressed in the direction 1831 to rotate the 1152. Disengagement of the secondary actuator 1152 allows the secondary actuator 1152 and the fixably coupled secondary grip portion 1153 to move independently of the primary actuator 1132, allowing the secondary electrode 211 to move from the primary electrode 207. Allows movement towards the reference point 102 independently of. The operation of the secondary disengagement device 1152 to disengage the secondary actuator 1150 from the primary electrode slider will be further described with reference to FIGS. 21 and 22.

With reference to FIGS. 19A and 19B, in some embodiments of user interface 1101, the secondary release device 1150 is pressed to allow movement of the secondary actuator 1152 independent of the primary actuator 1132. The secondary actuator 1152 may be partially rotated towards 1110. The secondary actuator 1152 is unlocked by pressing the secondary release device 1150, but the secondary actuator 1152 and the associated secondary grip 1153 have not yet moved. Therefore, the distal end 213 of the secondary electrode 211 has not yet moved towards the reference point 201 as compared to the distal end 209 of the primary electrode 207, as shown in the inset.

With reference to FIGS. 20A and 20B, the secondary actuator 1152 travels a distance of 2033 beyond the distal end 209 of the primary electrode 207 and beyond the reference point 201, the distal end 213 of the secondary electrode 211. Is extended. The secondary actuator 1152 is fixedly engaged with the secondary grip portion 1153. Therefore, the secondary grip portion 1153 also travels a distance of 2033. The fixable engagement of the secondary actuator 1152 with the secondary grip 1153 means that the user (not shown) exerts a force on the user (not shown) on only one side of the interface housing 1110 to move the secondary actuator 1152. Allows more force to be applied in extending the secondary electrode 211 than would be possible if this was not possible. This is, for example, in the secondary electrode 211 so that the distal end 213 of the coiled secondary electrode 211 can spiral into the tissue and anchor the distal end 213 of the secondary electrode 211 to the tissue. It can be important if the distal end 213 has been tucked into tissue (not shown). When the secondary actuator 1152 moves and extends the distal end 213 of the secondary electrode 211, the secondary release device 1150 is released to lock the position of the secondary actuator 1152 and thus of the secondary electrode 211. Lock the position.

When the secondary actuator 1152 moves the distance 2033, the actuator interlock 1140 also moves forward by the distance 2033. As used in this description, the term "forward" refers to the connector 1120 (FIG. 11) in which the user interface engages the port of an electrosurgical instrument such as port 748 of the bronchoscope 718 of FIGS. 7 and 8. It states the direction to go. In subsequent figures, the forward direction is consistently positioned either towards the left side of the figure or out of the figure. As will be further described later, the actuator interlock 1140 abuts on the primary release device 1130 (and thus the coupled primary actuator 1132) and the secondary grip portion 1153 (and thus the coupled secondary actuator 1152). When it is, the advance of the secondary actuator 1152 and the secondary grip portion 1153 is prevented. In various embodiments, for example, a pin (not shown) on the front end on the primary electrode slider 1533 is then on the actuator interlock 1140 to stop the movement of the secondary actuator 1152 and the secondary grip 1153. You can reach the end of the slot. Therefore, the actuator interlock 1140 serves to limit the movement of the secondary actuator 1152 and thus the length at which the distal end 213 of the secondary electrode 211 can extend beyond the distal end 209 of the primary electrode 207. The configuration of the actuator interlock 1140 and the operation of the actuator interlock will be described with reference to FIGS. 23-31.

With reference to FIG. 21, the secondary release device 1150 and the secondary actuator 1152 are shown in the locked position. As described above with reference to FIGS. 12-17, the secondary electrode 211 moves with the primary electrode 207 when the secondary release device 1150 is in the locked position. As described above, in the embodiment of FIG. 21, the secondary release device 1150 is integrated with the secondary actuator 1152. The secondary actuator 1152 is rotatably attached to the secondary electrode slider 2151 by a swivel shaft 2155. The spring 2157 keeps the secondary release device 2150 in the locked position when the secondary release device 1150 is not pressed. The secondary grip portion 1153 is fixedly coupled to the secondary electrode slider 2151 and moves (or does not move in some cases) with the secondary actuator 1152. When the secondary release device 1150 is in the locked position, the locking arm 2159 engages the locking notch 2139 in the primary electrode slider 1533. As shown in FIG. 21, the secondary electrode 211 is in an extended position where the primary actuator 1132 and the secondary actuator 1152 no longer move at the same time.

With reference to FIG. 22, the secondary release device 1150 and the secondary actuator 1152 are shown in the unlock position. As described above with reference to FIG. 19, the secondary release device 1150 is unlocked by pressing the secondary release device 1150, thereby deforming the spring 2157 into the secondary actuator 1152 and thus secondary. The actuator 1152 is rotated around the swivel shaft 2155 to the unlocked position. When the secondary actuator 1152 is rotated to the unlocked position, the locking arm 2159 is pulled out of the locking notch 2139, thereby allowing the secondary actuator 1152 to move. Next, by applying force to the secondary actuator 1152 and / or the secondary grip portion 1153, the surgeon (not shown in FIG. 22) is secondary as described above with reference to FIGS. 18-20. The electrode 211 can extend independently of the primary electrode 207.

It may be desirable to selectively allow the primary and secondary electrodes to move simultaneously according to various embodiments of the present disclosure and as described above with reference to FIGS. 4 and 12-14. .. However, as described with reference to FIG. 6, once the secondary electrode is deployed, it may be desirable to partially pull out the primary electrode while maintaining the position of the secondary electrode. Referring again to FIG. 4, the distal end 209 of the primary electrode 207 may be needle-shaped to penetrate the tissue at or adjacent to the reference point 201. The secondary electrode 211 moves with the primary electrode 207, thereby positioning the distal end 213 of the secondary electrode closer to the reference point 201. With reference to FIG. 5, the penetrating function provided by this exemplary configuration of the primary electrode 207 is useful for deploying the distal end 213 of the secondary electrode 211 at the desired position relative to the reference point 201. could be.

However, once the position of the primary electrode 207 is utilized to deploy the distal end 213 of the secondary electrode 211, the distal end 209 of the primary electrode 207 is partially retracted with reference to FIG. It may be desirable to apply current over the distance between the distal end 213 of the secondary electrode 211 and the distal end 209 of the secondary electrode 207. To provide a degree of selective movement of the distal end 213 of the secondary electrode 211 independent of the primary electrode 207 as shown in FIG. 6, and the distal end 209 of the primary electrode 207 is partially withdrawn. Maintaining the distal end 213 of the secondary electrode 211 while present is controlled by the actuator interlock 1140 operating with the primary and secondary actuators, as will be further described later with reference to FIGS. 23-31. Will be done.

With reference to FIG. 23, the actuator interlock 1140 is shown as being located inside the housing 1110 of the user interface. Specifically, the actuator interlock 1140 includes a secondary grip portion 1153 (moving with the secondary actuator as described above with reference to FIGS. 18 to 22) and a primary release device 1130 (FIGS. 12 to 17). It is positioned between (moving with the primary actuator 1132) as described above with reference to it. The primary release device 1130, the actuator interlock 1140, and the portion of the secondary grip portion 1153 extend from the housing 1110 through the channel 2349 under the housing 1110. As described above with reference to FIGS. 21 and 22, the secondary actuator 1152 engages with the primary electrode slider 1533 to move the secondary electrode slider 2151 together with the primary electrode slider 1533. In the actuator interlock 1140, at the first position shown in FIG. 23, the second end 2341 of the actuator interlock 1140 abuts on the tip 2331 of the secondary actuator 1153, and the first end of the actuator interlock 1140. The dimensions are such that the 2342 abuts on the trailing edge 2354 of the secondary electrode slider 1533, so that the actuator interlock 1140 is a primary release device towards the secondary grip 1153 (and thus the secondary actuator 1152) towards each other. Controls the relative movement of the 1130 (and therefore the primary actuator 1132). In various embodiments, a pin (not shown) secured to the primary electrode slider 1533 slides in a slot (not shown) in the actuator interlock 1140 and ends in a slot in the actuator interlock 1140. Provides a hard stop that limits the movement of the pins and, correspondingly, limits the movement of the secondary electrode slider 2151. Therefore, the secondary actuator 1140 operates to maintain the distance between the primary release device 1130 and the secondary grip portion 1153 while the actuator interlock 1140 is in the first position shown in FIG. ..

The actuator interlock 1140 also includes a lock bar (not shown in FIG. 23) that engages the primary release device 1130 as further described with reference to FIGS. 29-31. The lock bar prevents the primary release device from being engaged while the actuator interlock 1140 is in the first position, as will be further described later. The actuator interlock 1140 also engages a locking notch (not shown in FIG. 23) within the housing 1110 when the actuator interlock 1140 is in a second position, as will be further described later with reference to FIG. It also includes a lock tooth 2343 configured to do so. The lock tooth 2343 has a primary actuator (not shown in FIG. 23) and a primary release device 1130 as a secondary actuator (not shown in FIG. 23) while the secondary electrode (not shown in FIG. 23) stays in place, as will be further described later. Actuator interlock 1140 to allow the primary electrode (not shown in FIG. 23) to be partially retracted so that it can be moved independently of the secondary grip portion 1153 (not shown in FIG. 23). Works to fix the in place. Finally, as will be further described later, the lever 2344 allows the operator to engage the actuator interlock 1140 to rotate the actuator interlock 1140 between the first and second positions. To.

Referring to FIG. 24, in the first position of the actuator interlock 1140, the locking teeth 2343 are latent in the locking notch 2446 within the housing 1110 to lock the secondary electrode (not shown in FIG. 24) in place. It is in a position to engage with each other. The locking notch 2446 is formed after the secondary actuator and the secondary grip (not shown in FIG. 24) have moved to extend the distal end of the secondary electrode (not shown in FIG. 24) as described above. , Positioned to receive lock teeth 2343. As will be appreciated, and as will be further described later, when the actuator interlock 1140 rotates from the first position to the second position (FIGS. 26-28) shown in FIG. 24, the locking teeth 2343 It fits inside the locking notch 2446 and prevents the actuator interlock 1140 from moving relative to the housing 1110, for example when the primary release device 1130 is engaged and moves relative to the housing. As will be further described later, the use of the lock tooth 2343 to fix the position of the actuator interlock 1140 acts to lock the secondary electrode slider and prevent the movement of the secondary electrode, as will be further described later. Neither is shown in FIG. 24).

Referring to FIG. 25, the actuator interlock 1140 is arranged inside the housing 1110 with the actuator interlock 1140 shown in the first position. The actuator interlock 1140 rotates around the primary electrode 207 and the secondary electrode 211 inside the housing 1110. A lever 2344 extending out of the housing 1110 through channel 2349 allows the user to engage and rotate the actuator interlock 1140. As previously shown in FIGS. 18-20, the interlock lever 2344 is located in front of the secondary actuator 1152 and the secondary grip portion 1153, where the forward direction is on the left side of the figure.

Referring to FIG. 26, the actuator interlock 1140 is the first after the secondary electrode (not shown in FIG. 26) is deployed and before the primary electrode (not shown in FIG. 26) is partially retracted. It is shown in position 2. A lever 2344 is used to rotate the actuator interlock 1140 with respect to the housing 1110 to move the lock teeth 2343 of the actuator interlock 1140 to a second position within the channel 2349. There, the lock teeth 2343 engage the locking notch (not shown in FIG. 26) to secure the actuator interlock 1140 in place. As described above with reference to FIG. 23, the actuator interlock 1140 comprises the primary release device (not shown in FIG. 26) and the secondary grip portion 1153 while the actuator interlock 1140 is in the first position. Maintain the distance between. However, when the actuator interlock 1140 is in the second position as shown in FIG. 26, the actuator interlock 1140 heads towards the secondary grip 1153 (and thus the secondary actuator 1152) for the primary release device 1130 (and thus the secondary actuator 1152). Therefore, it no longer interferes with the relative operation of the primary actuator 1132). With the actuator interlock 1140 in the second position, the position of the secondary electrode slider 2151 is fixed with respect to the housing 1110 and therefore cannot move longitudinally with respect to the housing 1110. However, the primary actuator 1132 can move when engaged with the primary release device 1130. Therefore, the primary actuator (also not shown in FIG. 26) moves the primary actuator toward the secondary grip portion 1153 and does not move the secondary electrode (not shown in FIG. 26) but the primary electrode (not shown in FIG. 26). In order to store (not shown in FIG. 26), it is possible to move independently of the secondary actuator (also not shown in FIG. 26).

Referring to FIG. 27, a second to show how the locking teeth 2343 engage the locking notch 2446 within the housing 1110 to lock the secondary electrode (not shown in FIG. 26) in place. Another diagram of the actuator interlock 1140 at the position of is provided. The locking notch 2446 receives the lock teeth 2343 to lock the actuator interlock 1140 and locks the position of the secondary electrode slider 2151 in place, while when the primary release device 1130 is engaged, the primary actuator 1132 and the primary electrode The slider 1533 can be moved. Again, the lever 2344 allows the user to move the actuator interlock 1140 from a first position (shown in FIGS. 23-25) to a second position (shown in FIGS. 26-28). become able to. The lever 2344, which is slidable across the channel 2349 that allows the actuator interlock 1140 to move to a second position, has the property of a swipe lock that can be swiped from a first position to a second position. Will be understood.

Referring to FIG. 28, in the user interface 1101, the actuator interlock 1140 rotates inside the housing 1110 to a second position around the primary electrode 207 and the secondary electrode 211. In FIG. 28, FIG. 28 shows that the actuator interlock 1140 is rotating to the second position, whereas FIG. 25 shows the actuator interlock 1140 in the first position. It is similar to FIG. As described above with reference to FIGS. 26 and 27, the lever 2344 (from the actuator interlock 1140 extends out of the housing 1110 through the channel 2349) to rotate the actuator interlock 1140 to a second position. Is) is engaged by the user.

With reference to FIG. 29, another diagram of the actuator interlock 1140 is provided to show the operation of the lock bar 2945 associated with the actuator interlock 1140. The lock bar 2945 selectively impedes the movement of the primary release device 1130. As described above with reference to FIG. 5, when the primary electrode 207 is deployed with the distal end 209 at a desired position with respect to the reference point 201, the primary electrode 207 extends while the secondary electrode 211 extends. Remains stationary. The lock bar 2945 prevents the primary release device 1130 from engaging and prevents the primary actuator (not shown in FIG. 29) from moving, allowing the primary electrode to move while the secondary electrode is extended. (Neither is shown in FIG. 29).

Further referring to FIG. 29, the actuator interlock 1140 is shown in the first position, and as shown in FIG. 5, the secondary release device and the secondary actuator are engaged and the secondary electrode (whichever comes). (Not shown in FIG. 29) is positioned before being moved independently of the primary actuator and the primary electrode (also not shown in FIG. 29). In this position, the distal end 2957 of the lock bar 2945 does not engage the primary release device 1130. As described above with reference to FIGS. 12-17, the primary release device 1130 and thus the primary actuator 1132 may be operated to move the primary electrode (not shown in FIG. 29) as desired. For example, as also described above with reference to FIGS. 14 and 22, until the secondary release device is engaged with the secondary actuator, thus the secondary electrode is the primary actuator and the primary electrode as described above. Move with.

Referring to FIG. 30, with the actuator interlock 1140 in the first position, the secondary actuator (not shown in FIG. 30) and therefore the secondary grip 1153 are secondary electrodes (FIG. 30). (Not shown) is moving forward so as to extend. As a result, the actuator interlock 1140 moves forward and therefore the lock bar 2945 extends through the lock channel 3060 in the primary release device 1130. The lock channel 3060 includes a locking lobe 3062 and an open lobe 3064. When the actuator interlock 1140 is in the first position, the lock bar 2945 passes through the locking lobe 3062 of the lock channel 3060. As a result, if the user attempts to engage by pressing the primary release device 1130 as described with reference to FIG. 13, the lock bar 2945 will be attached to the first inner surface 3063 within the locking lobe 3062. Engages, thereby preventing the primary release device 1130 from being pressed. However, as further described with reference to FIG. 31, when the actuator interlock 1140 rotates to a second position, the lock bar 2945 rotates with the actuator interlock 1140 and the lock bar 2945 is an open lobe. Move into 3064. Here, the lock bar 2945 is no longer engaged with the first inner surface 3063 when the user attempts to press the primary release device 1130.

Referring to FIG. 31, the actuator interlock 1140 rotates inside the housing 1110 to a second position around the primary electrode 207 and the secondary electrode 211. With the actuator interlock 1140 rotated to the second position, the lock bar 2945 is rotating into the open lobe 3064. With the lock bar 2945 extending through the open lobe 3064, the user can press the primary release device 1130 without engaging the surface of the lock channel 3060 with the lock bar 2945. Thus, when the actuator interlock 1140 moves to a second position, the primary release device 1130 may be engaged to allow partial storage of the primary electrode 207, as described below.

With reference to FIGS. 32A and 32B, the secondary electrode 211 is unfolded and locked in place. Before the primary release device 1130 engages to start retracting the primary electrode 207 and pulls the distal end 209 of the primary electrode 207 away from the reference point 201, the distal end 213 of the secondary electrode 211 is referred to. Extending beyond point 201, the actuator interlock 1140 has moved to a second position within the housing 1110. When the secondary electrode 211 is extended and fixed in place in this way, the primary electrode 207 is moved to position the distal end 209 of the primary electrode 207 with respect to the distal end 213 of the secondary electrode 211 to generate current. The application can be facilitated to provide the desired treatment. As described with reference to FIGS. 29-31, once the actuator interlock 1140 is in the second position, the lock bar (not shown in FIG. 32A) does not interfere with the pressing of the primary release device 1130. Therefore, the user interface is configured for partial withdrawal of the primary electrode 207.

With reference to FIGS. 33A and 33, the primary release device 1130 is pressed in the direction 3331 towards the housing 1110 to release the primary actuator 1132. The primary actuator 1132 and the primary release device 1130 can now be moved rearward to partially retract the distal end 209 of the primary electrode 207 away from the reference point 201. The pressing of the primary release device 1130 allows the primary actuator to be moved relative to the housing 1110 as described above with reference to FIGS. 12A-17. As described above with reference to FIG. 22, the previous actuation of the secondary disengagement device 1150 disengaged the locking arm 2259 from the locking notch 2239 in the primary electrode slider 1533. As a result, the movement of the secondary actuator 1152 and the secondary electrode slider 2151 is no longer coupled to the primary electrode slider 1533. Referring again to FIG. 33A, the actuator interlock 1140 is rotated to a second position so as not to block the relative movement between the primary release device 1130 and the secondary grip portion 1153. Therefore, the primary actuator 1132 and therefore the primary electrode 207 can move independently of the secondary electrode 211.

With reference to FIGS. 34A and 34B, the primary actuator 1132 travels a distance of 3433 and stores the distal end 209 of the primary electrode 207 by the same distance of 3433. The primary release device 1130 is then released and moves in the direction 3431 as described above with reference to FIGS. 14A-17, where the primary actuator 1132 and the primary release device 1130 are then released with respect to the housing 1110. Locked in place. With the movement of the primary electrode 207, the indicator 1192 on the depth gauge 1190 also moves a distance 3433 to reflect the storage of the distal end 209 of the primary electrode 207. Therefore, in these embodiments, the user interface provides the distal end 209 of the primary electrode 207 and the distal end 213 of the secondary electrode 211 with the application of an electric current to treat the tissue at or near the reference point 201. Therefore, it can be positioned at a desired position close to the reference point 201.

With reference to FIG. 35, another embodiment of user interface 3501 may be used to position the primary and secondary electrodes with respect to a reference point (not shown in FIG. 35). In the case of the above-described embodiments, in these embodiments, the user interface 3501 moves parallel to or laterally to the axis 3521, or the curve 3523 around the axis 3521, as described below. Includes components that rotate along. In such an embodiment, the user interface 3501 includes a connector 3520 configured to engage an electrosurgical instrument such as a bronchoscope (not shown in FIG. 35). As a comparison to previous embodiments of the user interface, these embodiments of the user interface 3501 do not include sheath actuators. However, sheath actuators have been added to these embodiments of user interface 3501 as described in connection with previous embodiments and as described with reference to FIGS. 7-11. obtain. Alternatively, the sheath actuator may be integrated with the electrosurgical instrument as described above with reference to FIG. Also, although not shown in FIG. 35, as in the previous embodiment of the user interface 1101 of FIGS. 11-24, the lead wire from the switchable current source is received by the user interface 3501 and is primary and primary. A sheath containing a secondary electrode (not shown in FIG. 35) extends from the connector 3520.

The user interface 3501 includes some user controls whose operations and effects are described in more detail in the figures below. The primary release device 3530 coupled to the housing 3510 at the first end 3541 of the housing 3510 is configured to unlock the movement of the primary electrode (not shown in FIG. 35). The primary release device 3530 includes a release lever 3532 and a release spring 3533 that urge the release lever 3532 in the locked position. The primary release device 3530 engages with a slidable shaft 3536 that is slidably received within the front opening 3538 of the primary release device 3530. The slidable shaft 3536 is fixedly coupled to the connector 3520. The slidable shaft 3536 is configured to move back and forth along the axis 3521. The slidable shaft 3536 is fixably coupled to a depth setter rod 3534 which has the properties of a geared rack. As further described below, the depth setter rod 3534 is engaged by an actuator interlock 3540 to selectively fix the position of the slidable shaft 3536 and, as a result, the position of the primary electrode. ..

The slidable shaft 3536 includes a depth indicator 3539 that can be read by the front opening 3538 to determine the position of the primary electrode (not shown). The depth display unit 3539 is read by the front opening 3538 with reference to FIG. 11, similar to the display value of the display 1192 in the depth gauge 1190 for determining the position of the primary electrode (not shown in FIG. 35). It will be understood that it will be done. As will be further described later, the primary electrode is fixably coupled to the housing 3510 so that the sliding of the housing 3510 with respect to the slidable shaft 3536 controls the position of the primary electrode. In other words, in contrast to the previous embodiment of the user interface of FIG. 11 (including a separate primary actuator 1132), the housing of the user interface 3501 itself functions as a primary actuator for the primary electrode. The housing 3510 moves anteriorly and posteriorly along the axis 3521 to extend and retract the primary electrodes, respectively, as described below.

The secondary actuator 3552 is fixably coupled to a secondary electrode slider (not shown in FIG. 35) as described with reference to FIG. The sliding of the secondary actuator 3552 within the secondary channel 3554 allows the movement of the secondary electrode (not shown in FIG. 35). The secondary actuator 3552 is selective with respect to the housing 3510 by the interlock lever 3540 fixed to the secondary electrode slider 3551 (and thus with respect to the primary electrode whose movement is controlled by the movement of the housing 3510). Locked and unlocked. The interlock lever 3540 moves within the guide slot 3542 along the axis 3521 and along the curve 3523 around the axis 3521. The position of the interlock lever 3540 with respect to the guide slot 3542 controls the locking and unlocking of the secondary actuator 3550 and thus the secondary electrodes, as described below. In the initial configuration shown in FIG. 35, the lever end 3547 is located at the first position 3571 in the guide slot 3542 and the first position 3571 is at the second end 3555 of the secondary channel 3554. Fix the secondary actuator 3552. In an exemplary embodiment, the guide display 3543 may be included near the guide slot 3542 on the housing 3510 to guide the user in moving the interlock lever 3540 that controls the operation of the secondary actuator 3550. Further, as will be described later, in another configuration, the depth setting device rod 3534 may be engaged by the interlock lever 3540 to selectively lock the position of the primary electrode (not shown in FIG. 35).

With reference to FIG. 36, the exploded view of the user interface 3501 of FIG. 35 further details the configuration and operation of the user interface 3501. As already described with reference to FIG. 35, the user interface 3501 includes a connector 3520 fixably coupled to the end of the slidable shaft 3536. The slidable shaft 3536, which is fixedly coupled to the depth setting rod 3534, is slidably received within the front opening 3538 of the primary release device 3530. The release lever 3532 selectively releases the slidable shaft 3536 with respect to the front opening 3538 and is locked in position by a spring 3637 coupled between the primary release device 3530 and the release lever 3532. Be urged. The primary release device 3530 is fixedly coupled to the housing 3510. Beyond the primary release device 3530, the slidable shaft 3536 is slidably received within the opening 3655 in the secondary electrode slider 3551.

The secondary electrode slider 3551 is fixedly coupled to the secondary actuator 3552, which slidably moves within the secondary actuator channel 3554. Similarly, on the underside of the housing 3510, the secondary grip portion 3653 is coupled to the underside of the secondary electrode slider 3551 and extends through an additional channel 3655 of the housing 3510. As described above with reference to previous embodiments of the user interface, the secondary actuators 3552 and secondary are used to allow the secondary electrodes (not shown in FIG. 36) to penetrate the desired tissue for a particular application. By providing both of the following grips 3653, the user may be able to apply force as needed. When the secondary electrode slider 3551 is slidably received within the housing 3510, the electrode (not shown in FIG. 36) may extend through the front opening 3461 of the housing 3510.

In the exploded view of FIG. 36, additional aspects of the depth setter rod 3534 and the interlock lever 3540 are shown to further illustrate the configuration of the user interface 3501. The interlock lever 3640 is fixed to the secondary electrode slider 3551. The interlock lever 3540 is configured to engage the depth setter rod 3534. Specifically, in an exemplary embodiment, the depth setter rod 3534 includes a lower geared surface 3633 and an upper geared surface 3635. Similarly, the interlock lever 3540 includes a lower geared lock 3634 and an upper geared lock 3645. When the user operates the lever end 3547, the interlock lever 3540 rotates to engage the lower geared lock 3634 with the lower geared surface 3633 of the depth setter rod 3534 and also with the upper gear. The lock 3645 may be engaged with the upper geared surface 3635 of the depth setter rod 3534. In an exemplary embodiment, the lower geared lock 3634 and the upper geared lock 3645 are such that they rotate and engage on the lower geared surface 3633 and the upper geared surface 3635, as described below. It is a flexible member that is configured. When rotating over the lower geared surface 3633 and the upper geared surface 3635 of the depth setter rod 3534, the lower geared lock 3634 and the upper geared lock 3645 bend and the lower gear of the depth setter rod 3534 Pressure is applied to the attached surface 3633 and the upper gear attached surface 3635. The pressure applied in this way causes the interlock lever 3540 to rotate to bring the lower geared lock 3634 and upper geared lock 3645 to the lower geared surface 3633 and upper geared surface 3635 of the depth setter rod 3534. Prevents the interlock lever 3540 from moving relative to the depth setter rod 3534 until it is disengaged. When the lower geared lock 3634 and upper geared lock 3645 of the interlock lever 3540 engage the lower geared surface 3633 and the upper geared surface 3635 of the depth setter rod 3534, respectively, the slidable sleeve 3536 , Fixed to the depth setter rod 3534, and therefore moves with the interlock lever 3540. Therefore, the movement of the slidable sleeve 3536 is limited to the movement allowed by the guide slot 3542 that engages the interlock lever 3540, as described below.

With reference to FIGS. 37A and 37B, the user interface 3501 is the first configuration prior to the extension of the primary electrode 207 near the reference point 201 and beyond the distal end 105 of the sheath 103, as shown in the inset. It is indicated by. As mentioned above, the user interface 3501 does not include a sheath actuator for positioning the sheath 103, but the sheath actuator may be added to the user interface, for example, with a connector 3520 or an electrosurgical instrument (FIG. 37A). It may be included in (not shown).

In various configurations of the user interface 3501, the slidable shaft 3536 extends completely from the primary release device 3530 in response to the distal end 209 of the primary electrode 207 resting within the distal end 105 of the sheath 103. Is done. The secondary actuator 3552 is a secondary electrode stationary within the distal end 209 of the primary electrode 207 prior to deployment of the secondary electrode 211 as described above with reference to the previous embodiment of user interface 3501. It is located at the rear end 3555 of the secondary channel 3554 in the housing 3510 according to the distal end 213 of 211. The interlock lever 3540 also has a lever end 3547 positioned at the first end 3571 of the guide slot 3542 to secure the secondary actuator 3552 in place at the second end 3555 of the secondary channel 3554. It is in the initial position in the state of being.

Deployment of the primary electrode 207 and the secondary electrode 211 is initiated by the user engaging the primary release device 3530. In an exemplary embodiment, the primary release device 3530 engages by pressing the distal end 3729 of the release lever 3532 to deform the release spring 3637, allowing the slidable shaft 3536 to move. do. With the primary release device 3530 thus engaged to extend the primary electrode 207, the housing 3510 moves in direction 3708 along the slidable shaft 3536. Whether or not the desired position has been reached can be determined by reading the depth display portion 3539 on the slidable shaft 3536 at the front opening 3538 in the primary release device 3530. When the housing 3510 moves along the slidable shaft 3536 to move the primary electrode 3507 to the desired position, the distal end 3535 of the release lever 3532 is released, thereby deforming the release spring 3637. It can be returned to its non-existent state and locks the slidable shaft 3536 in place with respect to the primary release device 3530. The primary release device 3530 moves the rest of the primary release device 3530 and the user interface 3501 with respect to the slidable shaft 3536 before the distal end 3729 of the release lever 3532 is pressed to engage the primary release device 3530. It is configured to apply mechanical pressure to the slidable shaft 3536 so that it cannot. Similarly, as further described herein, when the distal end 3729 of the release lever 3532 is disengaged and the primary release device 3530 is disengaged, the rest of the primary release device 3530 and user interface 3501 slides. It cannot move with respect to a possible shaft 3536 and fixes the position of the primary electrode 207.

With reference to FIGS. 38A and 38B, the distal end 209 of the primary electrode 207 is extended to a desired position in the vicinity of the reference point 201 in the manner described with reference to FIGS. 37A and 37B. The movement of the housing 3510 with respect to the slidable shaft 3536 shown in FIG. 38A moves the distal end 209 of the primary electrode 207 closer to the reference point 201 to a desired position. Reaching the desired position can be verified by reading the depth display 3639 on the slidable shaft 3536 at the front opening 3538 in the primary release device 3530. Further, since the interlock lever 3540 fixes the secondary actuator 3552 at the second end 3555 of the secondary channel 3554, the movement of the housing 3510 also causes the distal end 213 of the secondary electrode 211 to be the primary electrode. The secondary electrode 211 is moved to the secondary actuator 3552 together with the movement of the primary electrode 207 while being positioned inside the distal end 209 of the 207.

Referring to FIG. 39, the interlock level 3540 engages the depth setter rod 3534 to lock the position of the secondary actuator (not shown in FIG. 39). As described above, the primary release device 3530 controls the passage of the slidable shaft (not shown in FIG. 39) through the front opening 3538 to the primary electrode (also not shown in FIG. 39). Control positioning. In addition to the anterior opening 3538, the rod opening 3928 receives the depth setter rod 3534 separately and slidably as the slidable shaft moves through the primary release device 3530.

As described above, the depth setting device rod 3534 has a lower geared surface 3633 and an upper geared surface that are selectively engaged by the lower geared lock 3634 and the upper geared lock 3645 of the interlock lever 3540, respectively. Includes 3635. The lever end 3547 allows the user to rotate the interlock lever 3540 to engage the geared locks 3634 and 3645 with the geared surfaces 3633 and 3635, respectively.

Referring to FIG. 40, the interlock lever 3740 has a lower geared lock and an upper geared lock (both not shown in FIG. 40) having a lower geared surface 3633 and an upper geared surface of the depth setter rod 3534. Without engaging the 3635, a lower geared lock and an upper geared lock (both behind the slidable shaft 3536, therefore not shown in FIG. 40) slide through the rod opening 3928. Can be positioned to move. In this configuration, the movement of the primary and secondary electrodes (both not shown in FIG. 40) is as described above with reference to FIGS. 37 and 38, both the primary release device and the housing (both not shown in FIG. 40). It is controlled by canceling (not shown). The position of the lever end 3547 is such that the lower geared lock and the upper geared lock do not fix the secondary electrode slider (also not shown in FIG. 40) to the depth setter rod 3534, which is a guide slot described below. (Not shown in FIG. 40) roughly coincides with the position of the lever end at the first, second, or third position. The user engages the lever end 4047 to engage the interlock lever 3540 with the lower geared surface 3633 and the upper geared surface 3635 of the depth setter rod 3534 as described below. It can rotate in the direction that guides each of the upper geared locks.

Referring to FIG. 41, the interlock lever 3540 is the lower geared lock 3634 of the interlock lever 3540 and the upper geared lock 3645 is the lower geared surface 3634 of the depth setter rod 3534 in front of the rod opening 3928. And the lever end 3547 is rotated by user operation so as to start engaging with the upper geared surface 3635. As mentioned above, in an exemplary embodiment, the lower geared lock 3634 and upper geared lock 3645 of the interlock lever 3540 are capable of being slightly deformed to engage the depth setter rod 3534. It is flexible. Therefore, the position of the lever end 3547 is such that the lower geared lock and the upper geared lock place the secondary electrode slider (also not shown in FIG. 40) on the depth setter rod 3534, as will be further described later. It roughly coincides with the position of the lever end 3547 that has not been fixed yet and is moving from the third position in the guide slot, which will be described later, to the fourth position in the guide slot (not shown in FIG. 40). do.

Referring to FIG. 42, the interlock lever 43540 is such that the lower geared lock 3634 and the upper geared lock 3645 of the interlock lever 3540 are the lower geared surface 3633 of the depth setter rod 3534 in front of the rod opening 3928. And to the lock position where it engages with the upper geared surface 3635, respectively, the lever end 3547 is further rotated by user operation. At the lock position, the lower geared lock 3634 and the upper geared lock 3645 secure the interlock lever 3540 to the depth setter rod 3534, and the fourth or fourth in a guide slot (not shown in FIG. 42) described below. It coincides with the lever end 3547 in the fifth position. In this position, the secondary actuator 3540 maintains the position of the secondary actuator (not shown in FIG. 42) even if the housing and thus the primary electrodes (neither shown in FIG. 42) move. The function of the interlock lever 3540 in positioning the primary and secondary electrodes will be further described later.

In FIGS. 43A-47C, side views and plan views of a second embodiment of the user interface are shown, along with an inset view showing the positions of the electrodes corresponding to the configuration of the user interface. In FIGS. 43A-47C, the lever end 3547 of the interlock lever 3540 is visible and tactilely sensed at the stage of operation of the user interface 3501, for example when extending the secondary electrode 211 or retracting the primary electrode 207. It should be understood that it provides an indicator that can be used.

With reference to FIGS. 43A-43C, the user interface 3501 is shown with the primary electrode 207 extended before any steps are taken to extend the secondary electrode 211. The primary release device 3530 is in a locked position that secures the housing 3510 to the slidable shaft 3536. As a result, the distal end 209 of the primary electrode 207 is anchored in place in close proximity to the reference point 201. The interlock lever 3540 is in the initial locking position indicated by the lever end 3547 of the interlock lever 3540 being located in the first position 3571 of the guide slot 3542. At this position, the lower geared lock and the upper geared lock of the interlock lever 3540 (not shown in FIGS. 43A and 43B) do not engage the depth setter rod 3534. However, the lever end 3547 at the first position 3571 prevents the interlock lever 3540 from moving along the axis 3521 (FIG. 35), thus causing the secondary actuator 3552 and the secondary electrode slider 3551 to secondary. Hold (prevent) in place within the next channel 3554. Therefore, since the primary electrode 207 is fixed in place and the secondary electrode slider 3551 is locked in place, the distal end 213 of the secondary electrode 211 is also locked in place with respect to the reference point 201. ..

Referring to FIGS. 44A-44C, the user interface 3501 is shown in a state in which the primary electrode 207 is extended and the actuator interlock 3540 is operated to unlock the movement of the secondary electrode 211. The primary release device 3530 remains in a locked position that secures the housing 2510 to the slidable shaft 3536. As a result, the distal end 209 of the primary electrode 207 remains fixed in place in close proximity to the reference point 302. The interlock lever 3540 moves to a second position indicated by the lever end 3547 of the interlock lever 3740 moving to a second position 4473 of the guide slot 3542. At this position, the lower geared lock and the upper geared lock (not shown in FIGS. 44A and 44B) of the interlock lever 3540 are at depth, as described with reference to FIGS. 44A-44C. Not yet engaged with the setter rod 3534. However, the lever end 3547 at the second position 4473 no longer prevents the interlock lever 3540 from moving along the axis 3521 (FIG. 35) within the secondary channel 3554. The lever end 3547 can therefore engage with limited movement within the guide slot 3542. Therefore, the secondary actuator 3552 and the secondary slider 3551 may also engage with the secondary channel 3554 with limited movement to move the secondary electrode 211 towards the reference point 201. With the primary electrode 207 thus fixed in place, the distal end 213 of the secondary electrode 211 can move towards the reference point 201 independently of the primary electrode 207.

With reference to FIGS. 45A-45C, the primary release device 3530 remains in the locked position and the secondary electrode 211 extends. As a result, the distal end 209 of the primary electrode 207 remains fixed in place in close proximity to the reference point 201. The interlock lever 3540 moves to a third position indicated by the lever end 3547 of the interlock lever 3540 being located at the third position 4575 of the guide slot 3542. At this position, the lower geared lock and the upper geared lock (not shown in FIGS. 45A and 45B) of the interlock lever 3540 are at depth, as described with reference to FIGS. 44A-44C. Not yet engaged with the setter rod 3534. When the user moves the secondary actuator 3552 to move the secondary electrode slider 3551 within the secondary channel 3554, the lever end 3547 moves to a third position 4575 in the guide slot 3542. The movement of the secondary actuator 3552 moves the distal end 213 of the secondary electrode 211 to a desired position beyond the reference point 201 while the distal end 209 of the primary electrode 207 is fixed in place. The insulator 515 on the secondary electrode 211 electrically insulates the distal end 213 of the secondary electrode 211 from the distal end 209 of the primary electrode 207, as described above.

With reference to FIGS. 46A-46C, the primary release device 3530 stays in the locked position, fixing the housing 3510 to the slidable shaft 3536, and the actuator interlock 3540 locks the movement of the secondary electrode 211. It is operated to do. As a result, the distal end 209 of the primary electrode 207 remains fixed in place in close proximity to the reference point 201. The interlock lever 3540 is moved to the fourth position 4677 by the user moving the lever end 3547 of the interlock lever 3540 to the fourth position 4677 of the guide slot 3542. In this position, as described with reference to FIG. 42, the lower geared lock 3634 and upper geared lock 3645 of the interlock lever 3540 are the lower geared surface 3633 and upper gear of the depth setter rod 3534. Each engages with the attached surface 3635. Therefore, the interlock lever 3540, and thus the secondary electrode slider 3551 and the secondary actuator 3552, are locked in place with respect to the depth setter rod 3534 by the lever end 3547 at the fourth position 4677 of the guide slot 3542. NS. Therefore, both the distal end 209 of the primary electrode 207 and the distal end 213 of the secondary electrode 211 are locked in place with respect to the reference point 201.

With reference to FIGS. 47A-47C, the primary release device 3530 is engaged to unlock the position of the housing 3510 with respect to the slidable shaft 3536, the housing 3510 portion of the distal end 309 of the primary electrode 207. It is moving in the direction 4781 so as to be stored. As a result, the distal end 209 of the primary electrode 207 is partially withdrawn from the reference point 201 towards the distal end 105 of the sheath 103. The interlock lever 3540 moves to the fifth position by moving the guide slot 3542 of the housing 3510 to the fifth position 4779 together with the lever end 3547 of the interlock lever 3540. In this position, as described with reference to FIG. 42, the lower geared lock 3634 and upper geared lock 3645 of the interlock lever 3540 are the lower geared surface 3633 and upper gear of the depth setter rod 3534. It continues to engage with each of the attached surfaces 3635. Therefore, the interlock lever 3540, and thus the secondary electrode slider 3551 and the secondary actuator 3552, are locked in place with respect to the depth setter rod 3534 by the lever end 3547 at the fourth position 4779 of the guide slot 3542. It remains. The movement of the housing 3510 moves the secondary electrode slider 3551 and the secondary actuator 3552 forward in the secondary channel 3554, and the secondary electrode slider 3551 moves the depth setter rod 3534 while the housing 3510 moves in the direction 4781. Allows it to remain locked in place. When the secondary electrode 211 is extended and fixed in place in this way, the primary electrode 207 is moved to position the distal end 209 of the primary electrode 207 with respect to the distal end 213 of the secondary electrode 211 to generate current. The application can be facilitated to provide the desired treatment. Therefore, according to these user interface embodiments, the distal end 209 of the primary electrode 207 and the distal end 213 of the secondary electrode 211 are prepared for application of an electric current to treat tissue at or near the reference point 201. It becomes possible to position it at a desired position in the vicinity of the reference point 201.

With reference to FIG. 48, another embodiment of the user interface 4801 is shown for electrode positioning. User interface 4801 includes components that move in parallel along axis 4821 or rotate along curve 4823 around axis 4821, as described further below. Further, as will be further described later, the user interface 4801 slides the outer housing 4810 along the axis 4821 to provide an actuator extending through the outer housing 4810 at the first end 4841 of the outer housing 4810. It is largely controlled by sliding and by rotating the outer housing around the axis 4821.

The user interface 4801 includes a connector 4820 for engaging a port on an electrosurgical instrument such as a bronchoscope, as described with reference to FIGS. 1, 7, and 8. The user interface 4801 also includes a sheath actuator 4804 for positioning the sheath (not shown in FIG. 48) as described above with reference to FIGS. 7-11. The sheath actuator 4804 includes a sheath lock 4806 that engages with the slidable sleeve 4812 and the slidable sleeve 4812 to secure the slidable sleeve 4812 in place, as will be further described later. The sheath actuator is inserted between the bronchoscope or user interface 4801 and the bronchoscope (not shown in FIG. 48) with reference to FIG. 35 and as described for another embodiment of user interface 3501. It will be appreciated that it may be part of a separate device.

The user interface 4801 includes an outer housing 4810 that is configured to allow operation of the electrodes. The outer sheath 4810 includes a first guide slot 4831 configured to receive and guide the movement of the primary actuator 4832 extending upward through the first guide slot 4831. The outer housing 4810 also includes a second guide slot 4851 configured to receive a secondary actuator (not shown in FIG. 48). As will be further described later, the rotation of the outer housing 4810 along the curve 4823 around the axis 4821 exposes and introduces the secondary actuator into the second guide slot 4851. When the secondary actuator is received through the second guide slot 4851, the secondary actuator may be anchored in place with a slidable actuator lock 4859, the operation of which will be described further below. Also, although not shown in FIG. 48, in the embodiment shown in FIGS. 1 and 11, the lead wire from the switchable current source is received by the user interface 4801 and includes the primary and secondary electrodes. The sheath extends from the user interface 4801 via a connector 4820.

Referring to FIG. 49, the outer housing 4810 includes a first guide slot 4831 that engages the primary actuator 4832. The primary actuator 4832 extends from the primary electrode slider 4914 as described below. The primary actuator 4832 extends upward through the guide slot 4831 in the outer housing 4810. By sliding the primary actuator 4832 through the first guide slot 4831, the user can extend, lock and partially retract the primary electrode (not shown in FIG. 49). The outer housing 4810 includes a second guide slot 4851 that is configured to receive the secondary actuator 4952. The secondary actuator 4952 has an intermediate guide slot 4933 in the primary electrode slider 4914 as described below. It extends through the secondary electrode slider 4916. An inclined portion 4957 adjacent to the second end 4958 of the second guide slot 4851 and below the outer housing 4810 is desired to house the secondary electrodes as described below. When the secondary actuator 4852 is engaged and knocked down.

The second guide slot 4851 in the outer housing 4810 has the rotation of the outer housing 4810 (FIG. 48) along the curve 4823 around the axis 4821 into the second guide slot 4851, as will be further described later. When the secondary actuator 4952 is exposed and introduced, it is configured to receive the secondary actuator 4952. When the secondary actuator is received through the second guide slot 4851, the secondary actuator may be anchored in place with a slidable actuator lock 4859, the operation of which will be described further below.

The primary electrode slider 4914 can be fixed in the longitudinal direction to the primary electrode (not shown in FIG. 49) so that the movement of the primary electrode slider 4914 in the longitudinal direction extends and stores the primary electrode without twisting the primary electrode. .. The primary electrode slider 4914 is slidably and rotatably received within the outer housing 4810. The primary actuator 4832 extends outward from the primary electrode slider 4914 so as to extend upward through the outer housing 4810. The primary electrode slider 4914 also includes an intermediate guide slot 4933 configured to receive a secondary actuator 4952 extending from the secondary electrode slider 4916.

The secondary electrode slider 4916 extends and stores the secondary electrode in the secondary electrode (not shown in FIG. 49) so that the movement of the secondary electrode slider 4916 in the longitudinal direction extends and stores the secondary electrode without twisting the secondary electrode. Can be fixed to. The secondary electrode slider 4916 is slidably received within the primary electrode slider 4914. The secondary actuator 4952 extends outward from the secondary electrode slider 4916 and is receptive through the intermediate guide slot 4933 in the primary electrode slider 4914. In an exemplary embodiment, the secondary actuator 4952 is spring-loaded or similarly extendable so that the second guide slot 4851 overlaps the intermediate guide slot 4933 in the primary electrode slider 4914. As the 4810 rotates, the secondary actuator 4952 extends upward through the second guide slot 4851. In another exemplary embodiment, when the outer housing 4810 is rotated to move the second guide slot 4851 so that it no longer overlaps the intermediate guide slot 4933 in the primary electrode slider 4914, the tilted portion 4959 becomes secondary. The actuator 4952 is engaged and compressed to fit under the outer housing 4810.

The sheath actuator 4804 includes a slidable sleeve 4812 that is fixably coupled to the sheath (not shown), is slidably received within the connector 4820, and is slidable to the sheath lock 4806. The operation of the sheath actuator 4804 will be further described with reference to FIGS. 50 and 51. In an exemplary embodiment, the slidable sleeve 4812 has an outer housing 4810 such that the movement of the electrodes (not shown in FIG. 49) made by using the user interface 4810 moves the electrodes relative to the sheath. Can be fixedly coupled to.

With reference to FIGS. 50A and 50B, the sheath actuator 4804 controls the position of the sheath 103 for use with the user interface 4801. Specifically, the position of the sheath 103 is such that the sheath 103 is desired by sliding the slidable sleeve 4812 in the connector 4820 and fixing the slidable sleeve 4812 in the sheath lock 4806. It is controlled by fixing it in position. The sheath actuator 4804 can operate in the same manner as the sheath lock 706 of FIG. 9 as described above. The slidable sleeve 4812 is fixably attached to the outer housing 4810 and is slidably received within the connector 4820. When the slidable sleeve 4812 positions the sheath 103 including the electrodes 207 and 211 in a desired position, the sheath lock 4806 is locked to secure the slidable sleeve 4812 in place. The sheath lock 4806 is a spring-loaded lock for fixing the slidable sleeve 4812 in place to fix the position of the sheath 103, a thumbscrew, or another analogy described above with reference to FIGS. 7-10. It may be the mechanism of.

As described above and as shown in the inset, in an exemplary embodiment, the distal end 213 of the secondary electrode 211 remains initially stationary only within the distal end 209 of the primary electrode 207. The secondary electrode 211 is received in the primary electrode. The distal end 209 of the primary electrode 207 then rests only within the distal end 105 of the sheath 103. Before using the sheath actuator 4804 to position the distal end 105 of the sheath 103 in close proximity to the reference point 201, the distal end of the sheath 103 is first located away from the reference point 201 or immediately adjacent to the reference point 201. It may stand still at the position where it was.

With reference to FIGS. 51A and 51B, the sheath actuator 4804 is used to position the distal end 105 of the sheath 103 closer to the reference point 201 shown in the inset, as also used with the user interface 4801. Move to. Relative movement of the outer housing 4810 towards the connector 4820 by a distance of 5019 moves the distal end 105 of the sheath 103 by the corresponding distance and the distal end 105 of the sheath 103 closer to the reference point 201. .. The distal end 209 of the primary electrode 207 and the distal end 213 of the secondary electrode 211 also approach the reference point 201. Relative movement of the outer housing 4810 towards the connector 4820 is achieved by the slidable sleeve 4812 being at least partially received within the connector 5120 and then secured to the sheath lock 4806 as described above. NS.

52A-57C show how the user interface 4801 moves the electrodes 207 and 211 based on the operation of the user interface 4801. Referring to FIG. 52A with respect to user interface 4801, the primary actuator 4832 extends from the primary slider 4914 through the first guide slot 4831 of the outer housing 4810 and is located in the first position 5233 within the first guide slot 4831. (As shown in cross-sections and top-down views taken along lines AA). Similarly, as shown in the inset, in the initial position, the distal end 209 of the primary electrode 207 is far from the sheath 103 with the distal end 105 of the sheath 103 positioned close to the reference point 201. It remains positioned within position 105. The distal end 213 of the secondary electrode 211 remains positioned within the distal end 209 of the primary electrode 207.

It should be noted that the secondary actuator 4952 and the intermediate guide slot 4933 are not yet exposed in the second guide slot 4851 in the outer housing 4810 and are therefore represented by dashed lines in the top-down view. .. As will be appreciated, the operation of the outer housing 4810 and the primary actuator 4832 is under the second guide slot 4851 in the outer housing 4810 where the secondary actuator 4952 can be subsequently engaged by the user, the secondary actuator 4952 and It provides an intermediate guide slot 4934.

It should also be noted that the primary actuator 4832 is fixably coupled to the primary electrode slider 4914 and the secondary actuator 4952 is fixably coupled to the secondary electrode slider 4916. Therefore, the linear or rotational movement of the primary actuator 4832 results in a corresponding movement of the primary electrode slider 4914 to move the primary electrode 5207. Similarly, the linear or rotational movement of the secondary actuator 4852 results in a corresponding movement of the secondary electrode slider 4916 to move the secondary electrode 211. Therefore, without explicitly describing the associated movement of each electrode slider, the movement of the primary actuator 4832 may be considered to result in the movement of the primary electrode 207, and the movement of the secondary actuator 4952 is two. It should be understood that the movement of the next electrode 211 may be considered to occur.

With reference to FIGS. 53A-53C, the primary actuator 4832 (extending through the first guide slot 4831 of the outer housing 4810 of the user interface 4801) is a cross-sectional view taken along line BB and a top-down view. As shown in, the user (not shown) has moved to a second position 5335 within the first guide slot 4831. The user may, for example, push the primary actuator 4832 forward to slide the primary actuator 4832 into the second position 5335 through the first guide slot 4831. Similarly, as shown in the inset, at the second position, the distal end 209 of the primary electrode 207 extends beyond the distal end 105 of the sheath 103 and into the target tissue 202 towards the reference point 201. do. The distal end 213 of the secondary electrode 211 remains positioned within the distal end 209 of the primary electrode 207.

The secondary actuator 4952 (extending through the intermediate guide slot 4934 of the primary electrode slider 4914 and the intermediate guide slot 4934 of the primary electrode slider 4914) is still exposed in the second guide slot 4851 in the outer housing 4810. However, it continues to be represented by dashed lines in the top-down diagram. However, it is understood that the movement of the primary actuator 4832 to the second position 5335 in the first guide slot 4831 brings the intermediate guide slot 4934 parallel to the second guide slot 4951 in the outer housing 4810. I want to be. As described with reference to FIGS. 54A-54C, the relative rotation of the primary actuator 4832 across the first guide slot 4831 is the second in the outer housing 4810 in which the secondary actuator 4952 can be subsequently engaged by the user. A secondary actuator 4952 and an intermediate guide slot 4934 are provided under the guide slot 4951 of the.

With reference to FIGS. 54A-54C, the primary actuator 4832 (extending through the first guide slot 4831 of the outer housing 4810 of the user interface 4801) is a cross-sectional view and top-down view taken along line CC. As shown in, the user (not shown) has moved to a third position 5437 within the first guide slot 4831. The user, for example, while sliding the primary actuator 4832 into the first guide slot 4831 to the third position 5437 while the primary electrode slider 4914 and the secondary electrode slider 4916 are fixed to rotate. Actuator 4832 can be rotated laterally. As shown in the inset, the relative positions of the electrodes 207 and 211 have not changed. The distal end 209 of the primary electrode 207 remains extended beyond the distal end 105 of the sheath 103 near the reference point 201, as shown in FIG. 53C. Similarly, the distal end 213 of the secondary electrode 211 remains positioned within the distal end 209 of the primary electrode 207.

However, due to the movement of the primary actuator 4832 to the third position 5437, the secondary actuator 4952 extends through the intermediate guide slot 4934 of the primary electrode slider 4914, this time in the second in the outer housing 5810 of the user interface 4801. Extend through the guide slot 4851 of. The intermediate guide slots 4934 in the primary electrode slider 4914 are superposed by a second guide slot 4851 in the outer housing 4810. At this position, the secondary actuator 4952 rests at the first position 5453 within the second guide slot 4851. As described with reference to FIGS. 55A-55C, the secondary actuator 4952 can now be engaged by the user to extend the secondary electrode 211.

With reference to FIGS. 55A-55C, the secondary actuator 4952 extends through the first guide slot 4851 in the outer housing 4810 of the user interface 4801 and extends through the first guide slot 4851 and in the first position 5453 in the second guide slot 4851. To the second position 5555. At the second position 5555, where the secondary actuator 4952 is located adjacent to the slidable actuator lock 4859, its operation is further described with reference to FIG. The primary actuator 4832 extends through the first guide slot 4831 of the outer housing 4810 and remains in the third position 5437 within the first guide slot 4831. The user (not shown) may, for example, push the secondary actuator 4952 to move the secondary actuator 4952 from the first position 5453 in the second guide slot 4851 to the second position 5555.

As shown in the inset, the movement of the secondary actuator 4952 extends the distal end 213 of the secondary electrode 211 beyond the distal end 209 of the primary electrode 207 to a position beyond the reference point 201. The electrical insulator 515 electrically insulates everything from the primary electrode 207 except for the distal end 213 of the secondary electrode 211. In contrast, the distal end 209 of the primary electrode 207 remains in the same position as shown in FIG. 54C, while the movement of the primary actuator 4832 towards the reference point 201 is restricted by the first guide slot 4831.

With reference to FIGS. 56A-56C, the secondary actuator 4952 extends through an intermediate guide slot 4934 in the primary electrode slider 4914 and is secured in place by a slidable actuator lock 4859. As described above with reference to other embodiments of the user interface, the distal end 213 of the secondary electrode 211 extends from the distal end 209 of the primary electrode 207 to a desired position opposite the reference point 201. Then, it may be desirable to keep the secondary electrode 211 in place while the distal end 209 of the primary electrode 207 is partially withdrawn. Since the secondary electrode 211 extends through the primary electrode 209, pulling out the primary electrode 209 may exert a force on the secondary electrode 211, potentially retracting the distal end 213 of the secondary electrode 211. There is. However, the slidable actuator lock 4859 helps prevent the secondary actuator 4952 from moving within the second guide slot 4851, thereby holding the distal end 213 of the secondary electrode 211 in place. Can be useful for.

The slidable actuator lock 4859 slides from the base portion 5669 to the second guide slot 4851 and engages with the secondary actuator 4952 so that the secondary actuator 4952 is in a second position within the second guide slot 4851. Prevents movement from 5555. As a result, when the primary actuator 4832 is engaged to retract the primary electrode 207, the secondary actuator 4952 and hence the secondary electrode 211 remain in place, as described with reference to FIGS. 57A-57C. ..

Referring to FIGS. 57A-57C, the primary actuator 4832 is the user (FIG. 57) with the secondary actuator 4952 secured to the second position 5555 in the second guide slot 4851 by the slidable actuator lock 4859. Engaged by (not shown) to partially retract the distal end 209 of the primary electrode 207. Specifically, the primary actuator 4832 (extending from the primary slider 4914 through the first guide slot 4831 of the outer housing 4810 of the user interface 4801) was taken along the top-down view and line EE. As shown in the cross section, it is moved by a user (not shown) to a fourth position 5739 within the first guide slot 4831. The user may, for example, push the primary actuator 4832 to slide the primary actuator 4832 through the first guide slot 4831 to the fourth position 5739. As shown in the inset, the secondary actuator 4952 is held in place by the slidable actuator lock 4859 at the second position 5555 in the second guide slot 4851 so that the secondary electrode 211 is far away. The position of the position end 213 remains unchanged with respect to the reference point 201. However, as shown in FIG. 57C, the distal end 209 of the primary electrode 207 is partially retracted closer to the distal end 105 of the sheath 103. When the secondary electrode 211 is extended and fixed in place in this way, the primary electrode 207 is moved to position the distal end 209 of the primary electrode 207 with respect to the distal end 213 of the secondary electrode 211 to generate current. The application can be facilitated to provide the desired treatment.

The following relates to the removal of the device. Since the primary actuator 4832 is located at the fourth position 5739 in the first guide slot 4831, the primary actuator 4832 moves to the third position 5437 in the first guide slot 4831 and is a slidable actuator. The primary electrode 207 cannot be stowed until the lock 4859 unlocks the secondary actuator 4952 and the secondary actuator 4952 is stowed in the first position 5453 in the second guide slot 4851. Therefore, accidental storage of the primary electrode 207 cannot occur while the secondary electrode 211 is in the extended position.

Referring to FIG. 58, in another embodiment the user interface 5801 is provided for positioning the electrodes transported by the sheath to a desired position at or near the reference point (neither is shown in FIG. 58). ). The user interface 5801 includes a sheath actuator 5804, a primary housing 5830, a secondary housing 5850, and a lock rod 5870. As described in detail below, the movement of the electrodes is to position the sheath using the sheath actuator 5804 and to position the lock rod 5870, along the curve 5823 around the axis 5821 of the user interface 5801. This is achieved by rotating the secondary housing 5850 and sliding the primary housing 5850 along the axis 5821. The primary housing 5830 is mechanically fixed to the primary electrode (not shown in FIG. 58) so that the sliding of the primary housing 5830 slides the primary electrode. Similarly, the secondary housing 5850 is mechanically fixed to the secondary electrode (not shown in FIG. 58) so that the sliding of the secondary housing 5850 slides the secondary electrode. In contrast to the previous embodiments described with reference to FIGS. 11-57, the user interface 5801 does not include actuators or levers used to manipulate the positions of the electrodes. Rather, the operation of the electrodes is performed by sliding and rotating the secondary housing 5850 and sliding the primary housing 5830, as described below.

With reference to FIG. 59, in certain embodiments, the connector 5820 engages a port on an electrosurgical instrument such as a bronchoscope, as described with reference to FIGS. 1, 7, and 8. It is configured in. The connector 5820 slidably receives the primary housing 5830 and the lock bar 5870. Once the sheath (not shown in FIG. 59) is placed in the desired position relative to the reference point (also not shown in FIG. 59), the sheath lock 5806 is used to secure the sheath in place and also as a reference. The position of the lock bar 5870 can be fixed relative to the point. The primary housing 5830 and lock bar 5870 are also slidably and rotatably received within the secondary housing 5850. As will be described in detail later, the sliding and rotation of the primary housing 5830 and the lock bar 5870 with respect to the secondary housing 5850 is the relative movement and positioning of the primary housing 5830 and the secondary housing 5850, and thus the primary and secondary. The relative movement of the next electrode and the fixation of the position are controlled respectively.

With reference to FIGS. 60A and 60B, the operation of the sheath actuator 5804 is described to illustrate the positioning of the sheath 105 and the lock bar 5870. Further, as will be described later, in the initial configuration, the sliding of the secondary housing 5850 also slides the primary housing 5830. Therefore, the sliding of the secondary housing 5850 slides the primary housing 5830 with respect to the connector 5820.

With reference to FIGS. 61A and 61B, the movement of the secondary housing 5850 at a distance of 6019 results in the primary housing 5830 advancing the distance 6019 into the connector 5820. Similarly, the sheath 103 advances into the body to move the distal end 105 of the sheath 103 toward the reference point 202. In this configuration, the movement of the secondary housing 5850 is also at the distal end 209 of the primary electrode 207 (stationary within the distal end 105 of the sheath 103) and the distal end 213 of the secondary electrode 211 (primary electrode 207). (Standing within the distal end 209 of) is aligned and advanced towards the reference point. Once the distal end 105 of the sheath 103 reaches the desired position relative to the reference point 202, the sheath lock 5806 can be used to lock the sheath 103 in place. In certain embodiments, the sheath lock 5806 can also lock the position of the lock rod 5870, thereby providing a reference position for positioning the primary housing 5830 and the secondary housing 5850, as described further below. Fix it.

62-64C illustrate the components of the user interface 5801. Referring to FIG. 62, the lock rod 5870 includes a positioning portion 6721 and a lock portion 6273. The positioning unit 6271 can be received and fixed in the connector 5820 that fixes the position of the lock rod as described above. The locking portion 6273 supports a plurality of outwardly extending teeth 6275, the outwardly extending teeth 6275 being one or more inwardly supported by a primary housing 5830 and a secondary housing 5850. Engaged by the teeth of the housing 5830 and 5850 to facilitate locking of the positions of the housings 5830 and 5850 and prevent the housings 5830 and 5850 from sliding along the lock rod 5870, as will be further described later.

With reference to FIG. 63A, a first side portion of the primary housing 5830 is shown. In certain embodiments, the primary housing 5830 is generally cylindrical so that it can slide and rotate within the chamber inside the secondary housing 5850 as further described with reference to FIGS. 64A-70C. The primary housing 5830 includes an outward guide slot 6333 configured to receive a guide member (not shown in FIG. 63A) extending inward from the secondary housing 5850. The engagement of the guide member with the guide slot 6333 controls the relative movement of the primary housing 5830 and the secondary housing 5850, as will be further described later.

With reference to FIG. 63B, a second side portion of the primary housing 5830 is shown. In certain embodiments, the primary housing 5830 includes a primary lock channel 6335 configured to receive a lock rod 5870. Within the primary lock channel 6335, when the lock rod 5870 is received within the primary lock channel, one or more inward teeth 6337 will cause the primary housing 5830 to slide relative to the lock rod 5870. It is configured to engage the teeth 6275 extending from the lock rod 5870 to prevent it.

With reference to FIG. 63C, a cross-sectional view of the primary housing 5830 shows a guide slot 6333 and a primary lock channel 6335. Since the guide slot 6333 does not have a lateral side of the guide slot 6333 that blocks the sliding of the guide member at this position, with reference to FIG. 63A, at a point along the primary housing 5830 where the cross section of FIG. 64C is taken. , Allows the guide member (not shown) to slide in the guide slot 6333. The primary lock channel 6335 includes a groove configured to receive the lock bar 5870. It should be noted that the primary housing 5830 defines an open core 6334 through which the primary electrode, secondary electrode, sheath, or other instrument (none of which is shown in FIG. 63C) can extend or be accepted. Is.

With reference to FIG. 63D, another cross section of the primary housing 5830 shows a guide slot 6333 and a primary lock channel 6335. With reference to FIG. 63A, the guide slot 6333 may have adjacent lateral sides that may block the sliding of the guide member at a point along the primary housing 5830 where the cross section of FIG. 64D is taken. Allows rotation of guide members (not shown) across. Within the primary lock channel 6335, one or more teeth 6337 prevent the primary housing 5830 from sliding along the lock bar 5870 when the lock bar 5870 is received within the primary lock channel 6335. Extends to engage the teeth 6275 on the lock bar 5870.

With reference to FIG. 64A, a side view of the secondary housing 5850 is shown. As mentioned above, in contrast to the embodiment of user interface 4801 of FIGS. 48-57, the secondary housing 5850, which is the outer housing, is extended with levers, separate actuators, or such levels and separate actuators. Does not support existing openings. Rather, the secondary housing 5850 itself is an actuator that is engaged by the user to manipulate the position of the electrodes (not shown in FIG. 64A). In the illustrated embodiment, the secondary housing 5850 is shown to have a cylindrical outer shape, but the secondary housing 5850 may support the knurled grip or hold the user interface. Alternatively, it may have different contours that may be desirable for operation.

With reference to FIGS. 64B and 64C, a cross section of the secondary housing 5850 shows an internal channel 6454 defined by an inner wall 6452 configured to slidably and rotatably receive the primary housing 5830. The secondary lock channel 6458 defined by the secondary channel wall portion 6456 is configured to receive the lock bar 5870, which slides within the secondary lock channel 6458 as described below. It can or can be moved across the secondary lock channel 6458 by rotation of the secondary housing 5850 for selectively rearranging the lock bar 5870.

Secondary channels 6458 are described in detail with reference to FIGS. 65A-65C, 66A-66C, 67A-67C, 68A-68C, 69A-69C, and 70A-70C. As such, it includes three lobes that control the relative movement of the housings 5830 and 5850 with respect to the lock bar 5870. With the lock bar 5870 in the first lobe 6461, the primary housing 5830 and the secondary housing 5850 can freely slide relative to the lock bar 5870. With the lock bar 5870 in the second lobe 6436, the secondary channel wall 6456 presses the lock rod 5870 to engage the lock rod 5870 with the teeth 6337 in the primary lock channel 6335 of the primary housing 5830. This prevents the primary housing 5830 from sliding with respect to the lock rod 5870. However, with the lock rod 5870 in the second lobe 6436, the secondary housing 5850 still slides freely with respect to the lock bar 5870. In the third lobe 6465, one or more inward teeth 6459 are configured to engage outward teeth 6275 extending from the lock bar 5870. Therefore, with the lock bar 5870 in the third lobe 6465, the secondary housing 5850 is blocked from sliding relative to the lock bar 5870. However, when the lock bar 5870 is in the third lobe 6465, the teeth 6337 in the primary lock channel 6335 of the primary housing 5830 no longer engage the lock rod 5870, so the primary housing 5830 is relative to the lock bar 5870. Can slide freely.

With reference to FIG. 64C again, the inwardly extending guide member 6455 is configured to be received in the guide slot 6333 of the primary housing 5830 described with reference to FIGS. 63A and 63C. The engagement of the guide member 6455 with the guide slot 6333 controls the relative movement of the primary housing 5830 and the secondary housing 5850, as will be further described later.

With reference to FIG. 65A, a side view of the user interface 5801 is shown with an initial configuration for extending both the primary electrode 207 and the secondary electrode 211 (FIG. 65D). 65A-70D are used to illustrate how to use the movement of the user interface 5801 to control the position of the distal end 209 of the primary electrode 207 and the distal end 213 of the secondary electrode 211 in the body. Specifically, the sliding and rotation of the outer secondary housing 5850 and the sliding of the inner primary housing 5830 position the electrodes 207 and 211 with respect to the reference point 202. In the side views of the user interface 5801 of FIGS. 65A, 66A, 67A, 68A, 69A, and 70A, the fitting 5820 and the secondary housing 5850 are shown in cut lines (represented by dashed lines). It should be noted that the relative movement of the primary housing 5830 with respect to the connector 5820 and the secondary housing 5850 is shown. In the display of FIGS. 65A, 66A, 67A, 68A, 69A, and 70A, the lock rod 5870 will also be positioned behind the user interface, and thus FIG. 65A, FIG. 66A, FIG. 67A, Not shown in FIGS. 68A, 69A, and 70A. However, the lock bar 5870 and the engagement of the lock bar 5870 with the primary housing 5830 and the secondary housing 5850 are shown in cross-sectional views such as those shown in the cross-sectional views of FIGS. 65B and 65C. The movement of the electrodes 207 and 211 with respect to the reference point is shown in the corresponding insets such as FIG. 65D.

Referring again to FIG. 65A, in the initial configuration extending both the primary electrode 207 and the secondary electrode 211, the guide member 6455 is received within the first transverse guide segment 6541 of the guide slot 6333 of the secondary housing 5850. (Fig. 65D). With the guide member 6455 of the secondary housing 5850 engaged to the first transverse guide segment 6541 of the guide slot 6333 of the primary housing 5830, the housings 5830 and 5850 are along the axis 5821 of the user interface 5801 (FIG. 58). Can only move at the same time.

With reference to FIGS. 65B and 65C, the lock rod 5870 is received by the first lobe 6658 of the secondary lock channel 6458 using the guide member 6455 in the first transverse guide segment 6541 of the guide slot 6333. .. Neither the tooth 6459 in the secondary lock channel 6458 of the secondary housing 5850 nor the tooth 6337 in the primary lock channel 6335 engages the lock rod 5870 when accepted by the first lobe 6561 of the secondary lock channel 6458. .. Thus, both the primary housing 5830 and the secondary housing 5850 can slide freely with respect to the lock rod 5870, but as described above, the engagement of the guide member 6455 and the guide slot 6333 is such that the primary housing 5830 And move the secondary housing 5850 at the same time (ie, move the same distance at the same time).

Referring to FIG. 66A, a side view of the user interface 5801 shows the time point at which the distal end 209 of the primary electrode 207 and the distal end 213 of the secondary electrode 211 extend to the reference point 201 as shown in FIG. 66D. It is shown in the second configuration. As described with reference to FIG. 65A, the engagement of the guide member 6455 with the guide slot 6333 of the secondary housing 5850 causes the primary housing 5830 and the secondary housing 5850 to move simultaneously by a distance of 6691. As shown in FIGS. 66B and 66C and as described above with reference to FIGS. 65B and 66C, the lock rod 5870 is in the first lobe 6461 of the secondary lock channel 6456, where the lock rod The 5870 is not engaged with the teeth 6459 in the secondary lock channel 6458 or the teeth 6337 in the primary lock channel 6335 of the secondary housing 5850, and the primary housing 5830 and the secondary housing 5850 are free with respect to the lock rod 5870. To be able to slide on.

Referring to FIG. 67A, the secondary housing 5850 rotates in the direction 6793 to move the guide member 6455 to the second segment 6473 of the guide slot 6333. With the guide member 6455 in the second segment 6734 of the guide slot 6333, the secondary housing 5850 is free to move relative to the primary housing 5830. However, the guide slot 6333 blocks further rotation of the guide member 6455 in the direction 6793.

With reference to FIGS. 67B and 67C, the rotation of the secondary housing 5850 results in the lock rod 5870 moving into the second lobe 6453 of the secondary lock channel 6458, where the secondary channel wall portion 6456 Acts on the lock rod 5870 so that the lock rod 5870 engages the teeth 6337 in the primary lock channel 6335 of the primary housing 5830 and thus prevents the primary housing 5830 from sliding relative to the lock rod 5870. Can be seen as. However, with the lock rod 5870 in the second lobe 6436, the secondary housing 5850 still slides freely with respect to the lock rod 5870. With reference to FIG. 67D, it can be seen that the rotation of the secondary housing 5850 does not result in the movement of the electrodes 207 and 211.

Referring to FIG. 68A, the secondary housing 5850 slidably moves a distance of 6891 independently of the primary housing 5830, from the distal end 209 of the primary electrode 207 to the opposite side of the reference point 202 from the secondary electrode 211. Extend the distal end 213 of. The guide member 5455 here extends into a third segment 6845 of the guide slot 6333, where the guide member 6455 is restricted from further sliding in the direction of the distance 6891, but is secondary to the primary housing 5830. It can move freely across the guide slot 6333 to allow rotation of the next housing 5850.

With reference to FIGS. 68B and 68C, the lock rod 5870 can be seen to remain within the second lobe 6453 of the secondary lock channel 6458. Therefore, the secondary channel wall portion 6456 continues to act on the lock rod 5870 so that the lock rod 5870 engages the teeth 6337 in the primary lock channel 6335 of the primary housing 5830, thus the primary housing 5830 on the lock rod 5870. Continue to prevent it from sliding against it. The secondary housing 5850 continues to slide freely with respect to the lock rod 5870 while the lock rod 5870 remains within the second lobe 6436.

With reference to FIG. 69A, the secondary housing 5850 rotates in direction 6993. The guide member 5455 here extends into a fourth segment 6847 of the guide slot 6333, where the guide member 6455 is restricted from further rotation in the direction 6993, but is then primary with respect to the secondary housing 5850. The relative sliding movement of the housing 5830 is possible.

With reference to FIGS. 69B and 69C, the lock rod 5870 can be seen moving into the third lobe 6465 of the secondary lock channel 6458. As a result, the lock rod 5870 no longer engages the teeth 6337 in the primary lock channel 6335 of the primary housing 5830, allowing the primary housing 5830 to slide with respect to the lock bar 5870. However, the teeth 6459 extending from the secondary housing 5850, where the rotation of the secondary housing 5850 receives the lock bar 5870 into the third lobe 6465 of the secondary lock channel 6458, are now on the lock rod 5870. Engage, thereby preventing sliding movement of the secondary housing 5850 with respect to the lock rod 5870. With reference to FIG. 69D, it should be noted that the rotation of the secondary housing 5850 does not result in the movement of the electrodes 207 and 211 again.

With reference to FIG. 70A, the primary housing 5830 travels a distance of 7091, partially retracting the primary housing 5830 within the secondary housing 5850, and the distal end of the secondary electrode 211 as shown in FIG. 70D. The distal end 209 of the primary electrode 207 is partially retracted away from 213. The primary housing 5830 is slidable with respect to the lock rod 5870. As described above with reference to FIGS. 69B and 69C, and as shown in FIGS. 70B and 70C, the rotation of the secondary housing 5850 causes the lock rod 5870 to the secondary lock channel within the secondary housing 5850. It was rotated into a third lobe 6465 of 6458. As a result, the lock rod 5870 was disengaged from the teeth 6337 in the primary lock channel 6355 of the primary housing 5830. With the lock rod 5870 in the third lobe 6465 of the secondary lock channel 6458 of the secondary housing 5850, the lock rod 5870 has teeth in the third lobe 6465 of the secondary lock channel 6458 of the secondary housing 5850. Engages with 6459, thereby preventing the secondary housing 5850 from sliding relative to the lock bar 5870. When the secondary electrode 211 is extended and fixed in place in this way, the primary electrode 207 is moved to position the distal end 209 of the primary electrode 207 with respect to the distal end 213 of the secondary electrode 211 to generate current. The application can be facilitated to provide the desired treatment.

Referring to FIG. 72, the user interface 5801 simultaneously brings the distal end 209 of the primary electrode 207 and the distal end 213 of the secondary electrode 211 to the reference point 202 as described above with reference to FIGS. 66A-65D. The secondary housing 5850 and the primary housing 5830 are shown moved in the direction 6691 to extend.

Referring to FIG. 73, the user interface 5801 is shown with the secondary housing 5850 rotated in direction 6793 to prevent the primary electrode 207 from moving relative to the reference point 202. The primary electrode 207 is therefore fixed in place, but the secondary housing 5850 is still free to slide as described above with reference to FIGS. 67A-67D.

Referring to FIG. 74, the user interface 5801 is secondary to extend the distal end 213 of the secondary electrode 211 beyond the reference point 202, as described above with reference to FIGS. 68A-68D. The housing 5850 is shown with the housing 5850 moved in the direction 6891.

Referring to FIG. 75, the user interface 5801 prepares for partial storage of the distal end 209 of the primary electrode 207, as described above with reference to FIGS. 69A-69D. The distal end 213 of 211 is shown with the secondary housing 5810 rotated in direction 6993 to secure it in place beyond the reference point 202.

Referring to FIG. 76, the user interface 5801 moves the primary housing 5830 in direction 7091 as described above with reference to FIGS. 70A-70D in order to partially retract the distal end 209 of the primary electrode 207. It is shown in the state of. The distal end 209 of the primary electrode 207 is therefore partially withdrawn from the reference point 202, leaving the distal end 213 of the secondary electrode 211 in place, thereby the electrodes 207 and 211 for hostility of the procedure. Prepare.
