Description

Treatment device operating device for endoscopic treatment {Apparatus for operating device using for endoscopic treatment}

The present invention relates to a device for manipulating various treatment instruments used in endoscopic treatment, and more particularly, to a treatment instrument manipulator for endoscopic therapy, which enables handling of treatment instruments with less force using the principle of a pulley. will be.

A medical endoscope is a medical instrument that is inserted into an internal organ such as the stomach or large intestine to allow close-up imaging and diagnosis of the inner wall of the organ. It plays an important role in the field of diagnosis and treatment of

In addition, with the development of optical or electronic control technology, it is possible to proceed with a necessary procedure through a passage secured inside the endoscope, not just photographing or tissue collection. The number of cases in which some surgical open operations performed in the past are being replaced by non-open procedures through an endoscope is increasing.

Furthermore, the range of possible procedures using an endoscope is gradually increasing, and various treatment devices have been developed for it. The treatment device includes a snare for removing a polyp, a hemoclip for hemostasis, an injector for injecting saline or a necessary chemical solution, and forceps for removing tissue.

This treatment device is connected to the tip treatment device through a flexible extension tube that is long and thin enough to pass through the passage inside the endoscope, a tip treatment tool installed at the tip of the extension tube, and a tensile wire inside the extension tube, and is located at the rear end of the extension tube. It consists of a manipulator that is positioned. The tip treatment device is operated by the user pulling the tension wire backward through the manipulator.

As a background technology related to a treatment instrument using an endoscope, Korean Patent Publication No. 10-2016-0111259 (a surgical instrument tube for an endoscope) has been disclosed. The disclosed surgical instrument tube has an end that enters into the insertion tube of the endoscope through a working channel provided in an endoscope that is inserted into the body for intestinal examination, and a start end that is connected to the adjustment bar of the endoscope from the outside of the working channel. ; The snare on one side of the core wire of the thin steel wire inserted into the guide hole inside the tube rod is exposed to the end of the tube rod, and the other side of the core wire includes a core body connected to the handle part of the adjustment rod, and is inserted into the insertion tube of the endoscope. a sensing unit for forming a sensing position at a position corresponding to the length of the insertion tube on the tube stand; At the distal end of the tube stand, a measuring unit for displaying a measurement scale to measure the size of the yong while exposed through the insertion tube of the endoscope; The core wire exposed at the end of the tube strip and the snare part are composed of a mark to distinguish it from the measurement part of the tube strip.

However, the above-described surgical instrument tube as well as the existing treatment instrument for endoscopic therapy has a disadvantage in that it takes a surprisingly large amount of force to pull the tensile wire. For example, it takes a lot of energy to remove a polyp by closing the snare's snare or to collect tissue with a forceps jaw. If the snare is not strongly tightened or the jaws are not tightly closed, the polyp or tissue is torn without cutting, so the operator pulls the tensile wire strongly to avoid tearing.

As described above, since the conventional treatment instrument operation device requires a lot of force during handling, the more the number of uses increases, the more uncomfortable the hand hurts, and the loss of strength in the hand may decrease the accuracy of the procedure.

1 is a perspective view of a treatment device 10 to which the operating device according to the first embodiment of the present invention is applied, and FIGS. 2 and 3 are dissection and disassembly of the treatment device operating device 30 according to the first embodiment of the present invention. is a perspective view. In addition, FIGS. 4A and 4B are diagrams for explaining the operation of the treatment device operating device 30 shown in FIG. 2 .

As shown, the treatment device 10 according to the present embodiment includes a manipulation device 30 and a tip treatment tool 21 . The tip treatment tool 21, although the jaw is exemplified in FIG. 1, includes all surgical instruments that can be used for endoscopic treatment. For example, it may include a snare or a jaw or clip for tissue collection. This tip treatment tool 21 is operated by pulling the tensile wire in common.

The operating device 30 of the present embodiment can pull the tension wire with less force by applying the pulley principle. As mentioned above, the conventional treatment device, to manipulate the tip treatment tool 21 (to pull the tensile wire), requires a lot of hand grip force, so it was not possible to perform an accurate operation due to pain in the hand.

The operation device 30 according to the first embodiment includes a case 40 , an operation means 70 , a flexible extension tube 31 , and a tension wire 33 .

The extension tube 31 is mounted on the opening 40B provided in the front of the case 40 and extends in the longitudinal direction to accommodate the tensile wire 33 therein. The front in this description is the direction in which the extension tube 31 is inserted into the body. In addition, the operation means 70 pulls the tension wire 33 backward in the longitudinal direction and is coupled to the mounting portion 40C at the rear of the case 40 .

As shown in FIG. 3 , the case 40 is assembled with an upper case part 43 and a lower case part 41 . The upper case part 43 and the lower case part 41 have the same internal structure and are combined to face each other to constitute one case 40 .

The lower case part 41 has an internal space open upward, and has a guide rail 41b, a blocking wall 41p, a supporter fixing part 41k, and a wire support part 41m in the internal space.

The guide rails 41b extend forward and backward in parallel with each other and provide a holder running path 41c therebetween. The holder running path 41c receives and supports the lower portion of the pulley holder 78 . Since the pulley holder 78 is accommodated in the holder running path 41c, there is no fear that the pulley holder 78 is separated to the side during linear motion.

A semi-cylindrical tube fixing part 41a is formed at the front end of the lower case part 41 . The tube fixing part 41a meets the tube fixing part 43a of the upper case part 43 to form a cylindrical opening 40B. The rear end of the extension tube 31 is inserted and fixed inside the opening 40B.

A supporter fixing part 41k and a blocking wall 41p are formed between the guide rail 41b and the tube fixing part 41a. The supporter fixing part 41k receives and supports the lower half of the wire supporter 79 as a rectangular groove open upward.

The blocking wall 41p is a plate-shaped member that blocks the supporter fixing part 41k and the holder running path 41c, and the upper end thereof faces the lower end of the blocking wall 43p of the upper case part 43 . As described above, since the upper blocking wall 43p and the lower blocking wall 41p are in contact with each other, the thickness of the case 40 is stably maintained. Unlike the upper and lower blocking walls 43p and 41p that are in contact with each other, the upper end surface 41d of the guide rail 41b and the lower end surface 43d of the upper guide rail 43b are spaced apart by a predetermined interval. A pulley 77 is fitted in a gap between the upper end surface 41d and the lower end surface 43d. It goes without saying that the pulley 77 has a thinner thickness than the gap.

In addition, the wire support portion 41m is a rectangular groove opened upward to receive and fix the lower half of the anchor member 76 . In addition, a wire hole 41g is provided on the opposite side of the wire support part 41m with the guide rail 41b interposed therebetween. The wire hole 41g is a groove through which a driving wire 75 to be described later passes.

In addition, a connecting portion 41e is positioned at the rear of one side of the lower case portion 41 . The connecting portion 41e is a portion to which the distal end of the guide rod 71 of the operating means 70 is fitted and coupled. A locking protrusion 41f is formed on the inner peripheral surface of the connecting portion 41e. The locking protrusion 41f is a protrusion inserted into the locking groove 71e of the distal end of the guide rod 71 .

As described above, the upper case part 43 has the same inner peripheral structure as the lower case part 41 . The upper case part 43 has an internal space open downward, and has a guide rail 43b, a blocking wall 43p, a supporter fixing part 43k, and a wire support part 43m in the internal space.

The guide rail 43b provides a holder running path 43c that extends forward and backward. The holder running path 43c receives and supports the upper portion of the pulley holder 78 . The guide rail 43b faces the guide rail 43b of the lower case part 41 and guides the linear motion of the pulley holder 78 .

A semi-cylindrical tube fixing part 43a is formed at the front end of the upper case part 43, and the tube fixing part 43a meets the tube fixing part 41a of the lower case part 41 and a cylindrical opening 40B. to form The supporter fixing part 43k is a rectangular groove that is opened downward, and the supporter fixing part 41k of the lower case part 41 and the wire supporter 79 are accommodated and fixed.

In addition, the blocking wall 43p is a plate-shaped member that blocks the supporter fixing part 43k and the guide rail 43b, and faces the upper end of the blocking wall 41p of the lower case part 41 . The wire support (43m) is a rectangular groove opened downward to receive and fix the upper half of the anchor member (76).

The wire hole 43g corresponds to the wire hole 41g of the lower case part 41, and when the lower case part 41 and the upper case part 43 are combined, a hole through which the driving wire 75 passes. to form

The connecting portion 43e meets the connecting portion 41e of the lower case portion 41 to form a mounting portion (40C in FIG. 1 ). A locking projection 43f is also provided on the connecting portion 43e. The mounting portion 40C receives and fixes the tip of the guide rod 71 . Of course, the locking protrusion 41f is also formed on the inner circumferential surface of the connecting portion 43e.

On the other hand, the pulley holder 78 is a block-shaped member that provides a receiving slit 78b into which the pulley 77 is fitted, and is fitted in the holder running paths 41c and 43c while supporting the pulley 77 . In addition, the rear end of the tension wire 33 is fixed to the pulley holder 78 . The tensile wire 33 is inserted into the extension tube 31 and extends in the longitudinal direction together with the extension tube 31 . Both the extension tube 31 and the tension wire 33 are flexible.

The pulley 77 is a member fitted to the pulley holder 78 through the support pin 78a, and is rotatable clockwise or counterclockwise around the support pin 78a. The pulley 77 is interposed between the guide rails 41b and 43b.

The wire supporter 79 is a member that supports the tension wire 33 while being fixed to the supporter fixing parts 41k and 43k.

Also, a tension spring 74a is sandwiched between the pulley holder 78 and the blocking walls 41p and 43p. The tension spring 74a serves to pull the pulley holder 78 forward where the opening 40B is located. By the action of the tension spring (74a), the tension wire (33) maintains a state in which it advances to the front (in a state where no external force is applied).

The operation means 70 is fixed to the rear of the case 40 through the mounting portion 40C, and serves to tension the driving wire 75 in the arrow a direction.

The operating means (70) includes a guide rod (71) and a slider (73). The guide rod 71 is a bar-shaped member extending in a straight line, and has a straight slit 71a in the center portion. In addition, an annular hooking hole 71c is formed at the rear end of the guide rod 71 . The slider 73 is coupled to the rear end of the drive wire 75 as a part that moves linearly while being supported by the slit 71a.

The user can pull the slider 73 in the direction of the arrow e while inserting the thumb into the hook hole 71c and holding the slider 73 with the middle and index fingers. A spring (not shown) is built in the guide rod 71 . The spring elastically supports the slider 73 in the direction of the arrow e, but provides an elastic force sufficient to keep the driving wire 75 in a taut state, and does not tension the driving wire 75 . That is, it has an elastic force smaller than that of the tensile spring 74a.

Since the configuration and role of the operation means 70 itself are general, a detailed description thereof will be omitted. In addition, in addition to the operating means shown in Figure 2, the configuration of the operating means can be varied as long as the wire can be pulled.

On the other hand, the driving wire 75 is a flexible wire spanning the pulley 77 , and one end is supported by the wire support parts 41m and 43m through the anchor member 76 , and the other end is fixed to the slider 73 . .

When the slider 73 is moved in the direction of the arrow e in FIG. 4A, the driving wire 75 is pulled in the direction of the arrow a, and the pulley 77 is rotated in the direction of the arrow f, and at the same time, the pulley holder 78 is moved in the direction of the arrow g. move As the pulley holder 78 moves backward, the tension wire 33 is pulled toward the case 40 and operates the tip treatment tool 21 . At this time, the tension spring 74a is stretched.

By applying the pulley 77 in the force transmission path in this way, it is possible to pull the tensile wire 33 with less force. The number of applications of the pulley 77 may vary according to the embodiment.

When the force applied to the slider 73 is removed while the tension wire 33 is pulled as described above, the tension spring 74a is elastically restored, and the pulley holder 78 is pulled in the direction of the arrow h to return it to its original position.

5 is an exploded perspective view showing a modified example of the treatment device operating device 30 according to the first embodiment of the present invention.

Hereinafter, the same reference numerals as the above reference numerals indicate the same members having the same functions, and repeated description thereof will be omitted.

Referring to the drawings, an end fixing part 41q is provided on one side of the rear end of the lower case part 41 . Of course, another end fixing part (not shown) corresponding to the end fixing part 41q is also formed in the upper case part 43 . The end fixing part 41q is in close contact with each other with the driving wire 75 interposed therebetween to clamp and fix the driving wire 75 .

6 is a view showing another modified example of the treatment device manipulation device 30 according to the first embodiment of the present invention, Figures 7a and 7b are views for explaining the operation of the manipulation device shown in Figure 6 .

As shown, the side extension 78c is integrally formed on both sides of the rear end of the pulley holder 78, and a compression coil spring 74b is installed between the side extension 78c and the inner wall 41r. has been The inner wall 41r is an inner wall surface of the lower case part 41 and the upper case part 43 . The compression coil spring (74b) surrounds the drive wire (75).

The compression coil spring 74b is compressed when moving the slider 73 in the direction of the arrow e of FIG. 7A and causes the pulley 77 to move backward. As the slider 73 is moved rearward, the pulley 77 rotates in the arrow f direction and is pulled rearward at the same time. When the force pulling the slider 73 is removed, the compression coil spring 74b expands and the pulley holder 78 returns to its original position.

8A and 8B are diagrams for explaining another configuration and operation of the treatment device operating device 30 according to the second embodiment of the present invention, and FIG. 9 is a side view of the dual pulley 50 shown in FIG. 8A. to be.

As shown, the operating device 30 according to the second embodiment includes a case 40, a torsion shaft 55, a dual pulley 50, a tension wire 33, a driving wire 75, an operating means ( 70).

The case 40 is assembled with a lower case part 41 and an upper case part 43 and has an accommodating space (no reference numeral) therein. Further, an opening 40B is provided at the front of the case 40 and a mounting portion 40C is provided at the rear thereof. The shape of the case 40 may vary.

The torsion shaft 55 has a torsion spring (not shown) as a rotation shaft whose upper and lower ends are respectively supported by the upper case part 43 and the lower case part 41 . The torsion shaft 55 is axially rotatable in a clockwise or counterclockwise direction by an external force, and is elastically biased without axial rotation when an external force is not applied. For example, if you turn it clockwise and release it, it rotates counterclockwise and returns to the initial position, and if it is rotated and released in a counterclockwise direction, it turns clockwise and returns to the initial position.

The dual pulley 50 is mounted on the torsion shaft 55 . The dual pulley 50 has a first pulley 51 and a second pulley 53 that have different diameters and have the same central axis of rotation. The first pulley 51 has a relatively larger diameter than the second pulley 53 .

In addition, the tension wire 33 is wound around the pulley surface 53b of the second pulley 53 , and the driving wire 75 is wound around the pulley surface 51b of the first pulley 51 . The driving wire 75 passes through the mounting portion 40C in a state wound around the first pulley 51 and is fixed to the slider 73 .

In order to connect the drive wire 75 to the first pulley 51, a first tip fixing groove 51a is formed in the pulley surface 51b. The first tip fixing groove 51a is a groove extending from the surface of the pulley surface 51b toward the torsion shaft 55 to receive and fix the fixing tip 75a. The fixing tip (75a) is a metal piece fixed to the end of the driving wire (75), and is a part fixed to the first tip fixing groove (51a).

In addition, in order to fix the tension wire 33 to the second pulley 53 , a second tip fixing groove 53a is positioned on the pulley surface 53b of the second pulley 53 . The second tip fixing groove (53a) is a groove extending from the surface of the pulley surface (53b) toward the torsion shaft (55). In addition, a fixing tip (33a) is fixed to the end of the tensile wire (33). The fixing tip (33a) is a member for clamping and fixing the end of the tension wire (33), and is fixedly embedded in the second tip fixing groove (53a).

In particular, the tensile wire 33 and the driving wire 75 are wound in opposite directions. That is, on the drawing. The tensile wire 33 is wound in a clockwise direction, and the driving wire 75 is wound in a counterclockwise direction. The reason why the winding direction is designed in this way is so that the tension wire 33 is wound when the driving wire 75 is unwound, and the tension wire 33 is unwound when the driving wire 75 is wound.

In the treatment apparatus operating device 30 of the second embodiment having the above configuration, when the slider 73 is pulled in the direction of the arrow e, the dual pulley 50 rotates in the direction of the arrow k, and accordingly, the second pulley 53 Winds the tension wire (33). The tensile wire 33 is pulled in the direction of the arrow m.

Since the driving wire 75 is wound around the first pulley 51 having a relatively larger diameter than the second pulley 53, according to the principle of the moment, the tension compared to the force pulling the driving wire 75 in the direction of the arrow e The pulling force of the wire 33 in the direction of the arrow m is large. In other words, when the tension wire 33 is to be pulled with a force of 100, the driving wire 75 may be pulled with a force less than 100. It means that the hand can be handled with less force compared to the previous operation device.

8B is a state in which the slider 73 is completely moved in the direction of the arrow e. It can be seen that the driving wire 75 is almost unwound, and the tensile wire 33 is wound around the second pulley 53 .

In this state, when the force applied to the slider 73 is removed, the torsion shaft 55 rotates in the direction of the arrow r and returns to its initial position. At this time, the tensile wire 33 is released from the second pulley 53 , and the driving wire 75 is wound around the first pulley 51 .

As mentioned above, although the present invention has been described in detail through specific embodiments, the present invention is not limited to the above embodiments, and various modifications are possible by those of ordinary skill within the scope of the technical spirit of the present invention.
