Referring to fig. 1-9, in the present embodiment, when the electrocoagulation forceps clamp tissue to perform electrocoagulation and other treatments on the tissue, the position where the forceps head 200 of the electrocoagulation forceps clamps the tissue is accurate and reliable, the treatment effect is good, the safety is high, and the success rate of the operation is high.

It should be noted that the electrocoagulation pliers may be single-stage electrocoagulation pliers, or may be bipolar electrocoagulation pliers, and in this embodiment, the electrocoagulation pliers are exemplified as bipolar electrocoagulation pliers.

Referring to FIGS. 1-3, in the present embodiment, the electrocoagulation pliers comprise:

a base member 100;

two binding clip 200, two binding clip 200 are connected with the base member 100, at least one of the two binding clip 200 can rotate relative to the base member 100, so that the two binding clip 200 can have a closed state and an open state which are switched with each other;

and a driving mechanism 300, the driving mechanism 300 comprises a driving member 310 and an actuating member 320 which are in transmission connection, the driving member 310 and the actuating member 320 are both in sliding fit with the base member 100, and the sliding directions of the driving member 310 and the actuating member 320 are opposite; the actuating member 320 is configured to slide when the driving member 310 slides relative to the base member 100 to drive at least one of the jaws 200 to move, so as to switch the two jaws 200 between the open state and the closed state. In other words, the driving member 310 and the actuating member 320 form a linkage structure, and the driving member 310 and the actuating member 320 move simultaneously or are stationary simultaneously; when the driving member 310 slides relative to the base member 100 along a first direction, the driving member 310 drives the actuating member 320 to slide relative to the base member 100 along a second direction opposite to the first direction.

When the electrocoagulation pliers are used, the pliers heads 200 of the electrocoagulation pliers can be conveyed to a position to be treated by using an endoscope, and when the electrocoagulation pliers are in an initial state, the two pliers heads 200 are in an open state. The driving member 310 is operated to slide relative to the base member 100 along a first direction, so as to drive the actuating member 320 to slide relative to the base member 100 along a second direction opposite to the first direction, that is, the actuating member 320 slides close to one of the two forceps heads 200, when the actuating member 320 slides, the actuating member abuts against at least one of the two forceps heads 200 and drives the corresponding forceps head 200 to move, so that the two forceps heads 200 are close to each other, the two forceps heads 200 are switched from an open state to a closed state, so as to clamp the tissue between the two forceps heads 200, and then the treatment such as electrocoagulation can be performed.

In the process of clamping tissues by the two forceps heads 200, the two forceps heads 200 can be accurately positioned at the positions of the tissues to be clamped under the cooperation of an endoscope, so that the tissues are positioned between the two forceps heads 200, and when the tissues are clamped, the base member 100 is used as a base member, the position of the base member 100 is kept unchanged, because the forceps heads 200 are connected with the base member 100, the positions of the two forceps heads 200 positioned on the base member 100 are unchanged, only the driving member 310 is required to be operated to drive the actuating member 320 to slide relative to the base member 100, and the two forceps heads 200 are driven by the actuating member 320 to rotate relative to the base member 100 to be closed. That is, in the process of closing the two forceps heads 200, the forceps heads 200 only rotate relative to the base member 100 around the positions connected with the base member 100, and do not move forward or backward relative to the tissue, the clamping positions of the forceps heads 200 are not changed, and the tissue is not pulled in the process of clamping the tissue.

Referring to fig. 5, in the present embodiment, optionally, the base member 100 includes a supporting tube 110, a mounting head 120 and a spring tube 130, the mounting head 120 is inserted into one end of the supporting tube 110 and is fixedly connected to the supporting tube 110, and the mounting head 120 and the supporting tube 110 are relatively fixed in the circumferential direction of the supporting tube 110, that is, they do not rotate relatively around the axis of the supporting tube 110, so that the position is more stable. The spring tube 130 is connected to an end of the support tube 110 remote from the mounting head 120.

Referring to fig. 6, further, the support tube 110 includes a first end 111 and a second end 112, two avoidance gaps 113 are disposed on a tube wall of the support tube 110, an opening side of each avoidance gap 113 is located on an end surface where the first end 111 is located, and the two avoidance gaps 113 are uniformly arranged at intervals in a circumferential direction of the support tube 110, in other words, an included angle between the two avoidance gaps 113 is 180 degrees. Two avoiding grooves 114 are further arranged on the outer pipe wall of the support pipe 110, the two avoiding grooves 114 are communicated with the two avoiding notches 113 in a one-to-one correspondence manner, that is, one end of the avoiding groove 114 is communicated with one side of the avoiding notch 113 far away from the first end 111, and the avoiding groove 114 can be an arc-shaped groove.

Referring to fig. 7, further, a mounting hole 121 is formed in the middle of the mounting head 120. The outer circumferential surface of the mounting head 120 is provided with two positioning grooves 122, and the two second grooves are arranged at regular intervals in the circumferential direction of the mounting head 120, in other words, the angle between the two mounting grooves is 180 degrees. Each positioning groove 122 extends along the extending direction of the mounting hole 121, and both ends of each positioning groove 122 extend to both end surfaces of the mounting head 120 in the extending direction of the mounting hole 121, i.e., each positioning groove 122 is a through groove. When the mounting head 120 is inserted into the first end 111 of the support tube 110, the mounting hole 121 is coaxial with the lumen of the support tube 110, and the wall of the support tube 110 covers the opening of the mounting groove, so that the wall of the support tube 110 and the outer peripheral surface of the mounting head 120 form a through channel 140 for passing the lead 400 at the position of the mounting groove. Meanwhile, the end surface of the mounting head 120 away from the first end 111 of the support pipe 110 is spaced from the side of the relief notch 113 away from the first end 111, that is, the mounting head 120 and the support pipe 110 define the first through hole 150 together at the position of the mounting notch.

It should be noted that the lumen of the support tube 110 may be referred to as a receiving channel 115, and the first through hole 150 communicates with the receiving channel 115.

Furthermore, a steering structure 160 is installed in the support tube 110, and the steering structure 160 may be a steering rod, the cross-sectional shape of the steering rod is circular, or at least a part of the outer profile of the cross-sectional shape of the steering rod is arc-shaped. The cross section of the steering rod is a section perpendicular to the direction of extension of the steering rod. The extending direction of the steering rod is perpendicular to the extending direction of the support tube 110, and the steering rod is positioned between the first end 111 of the support tube 110 and the joint of the avoidance groove 114 and the avoidance notch 113.

In other embodiments, the diversion structure 160 is disposed as a portion of the wall of the first through hole 150, i.e., the sidewall of the relief notch 113 away from the first end 111.

Alternatively, the support tube 110 and the mounting head 120 may be fixedly connected by screws. Specifically, when the mounting head 120 is inserted into the first end 111 of the support tube 110, screws penetrate through the support tube 110 and the mounting head 120 at the same time, so that the mounting head 120 and the support tube 110 are fixed, and the number of the screws can be set as required.

It will be appreciated that the function of the spring tube 130 is to facilitate bending in the endoscope channel in response to bending of the endoscope channel to facilitate reaching the location to be treated, i.e., the length of the spring tube 130 is constant. In operation, the spring tube 130 is used as a base member to keep the position thereof fixed, that is, to ensure the positions of the support tube 110 and the mounting head 120 to be fixed, and finally to ensure the position of the forceps head 200 to be fixed.

Referring to fig. 1, fig. 2 and fig. 3, in the present embodiment, optionally, the forceps head 200 includes a forceps arm 210 and a conductive forceps body 220, the forceps body is connected to the forceps arm 210, the forceps arm 210 is a flexible arm, and the forceps arm 210 is inserted into the mounting hole 121 of the mounting head 120. The clamp arms 210 are used to generate a movement trend of the corresponding conductive clamp body 220 from a closed state to an open state. In other words, when the actuator 320 does not apply a force to the forceps arms 210 to close the forceps arms 210, the two forceps arms 210 are opened by their own elastic force to form an opened state, which may also be referred to as an initial state of the electrocoagulation forceps, and in the initial state, the two forceps arms 210 are opened to form a substantially V-shape for grasping tissue.

Alternatively, the jawarms 210 may be metal spring tabs.

Optionally, each of the forceps arms 210 is provided with an escape opening 211 for passing the wire 400 therethrough.

Further, the binding clip 200 includes an insulating layer 230, wherein the insulating layer 230 covers the outside of the binding clip 210 and is located between the binding clip 210 and the conductive binding clip 220. Optionally, the insulating layer 230 is injection molded with the clamp arm 210 and the conductive clamp body 220. Further, concave-convex structures are arranged on the clamp arm 210 and the conductive clamp body 220, when the insulating layer 230 is injected between the clamp arm 210 and the conductive clamp body 220, the insulating layer 230 is clamped and matched with the concave-convex structures, the insulating effect between the clamp arm 210 and the conductive clamp body 220 is achieved, the effect of fixedly connecting the clamp arm 210 and the conductive clamp body 220 is achieved, and the structure is firm and reliable.

In this embodiment, the two forceps heads 200 are identical in structure. Obviously, in other embodiments, the two forceps heads 200 may not be configured identically, for example, one of the forceps arms 210 of the two forceps heads 200 may be configured as a resilient arm.

In this embodiment, the two forceps arms 210 of the two forceps heads 200 are both elastic arms, and each forceps arm 210 is opened by a certain angle, so that the forceps head can be clamped more widely and used more flexibly and reliably.

Obviously, in other embodiments, the jawarm 210 may be rotatably connected to the mounting head 120 through a rotating shaft, the rotating shaft is sleeved with a torsion spring, the torsion spring is connected to the rotating shaft and the mounting head 120 at the same time, the torsion spring is used to generate a movement trend of the corresponding conductive jawset 220 to switch from the closed state to the open state, and it is also possible to achieve automatic resetting of the jawarm 210 after the external force applied to the jawarm 210 by the actuating member 320 is removed.

In this embodiment, optionally, the electrocoagulation pliers further includes two wires 400, the two wires 400 are inserted into the receiving channels 115 of the spring tube 130 and the support tube 110, and penetrate through the first through hole 150 communicated with the receiving channel 115, and after penetrating through the first through hole 150, the wires 400 pass through the avoiding opening 211 on the pliers arm 210 and then are connected with the corresponding conductive pliers body 220.

Referring to fig. 8 and fig. 4, in the present embodiment, optionally, the driving member 310 includes two first pulling cables 311, a pressing pipe 312 and a second pulling cable 313, one end of the two first pulling cables 311 is gathered and connected to the pressing pipe 312, the pressing pipe 312 is connected to the second pulling cable 313, and the second pulling cable 313 is inserted into the spring tube 130. One end of the two first pulling cables 311 far away from the pressing pipe 312 passes through the first through hole 150 of the supporting pipe 110 after passing around the steering structure 160, the number of turns of the first pulling cable 311 passing around the steering structure 160 is not limited, and may be one turn, multiple turns or less than one turn, as long as the first pulling cable 311 contacts with part of the steering structure 160. The first pulling cable 311 is located in the avoiding groove 114 after penetrating out of the first through hole 150, and the first pulling cable 311 is connected with the actuating member 320. Due to the structural design of the avoidance groove 114, the avoidance groove 114 can accommodate the first cable 311, so that the first cable 311 is prevented from influencing the assembly of the actuating member 320 and the support pipe 110. In an initial state, that is, when the two jaws 200 are opened, the position where the first cable 311 is connected to the actuating member 320 is farther away from the jaws 200 than the position where the first cable 311 is connected to the steering structure 160, that is, the position where the first cable 311 is connected to the steering structure 160 is located between the position where the first cable 311 is connected to the actuating member 320 and the jaws 200, so that when the second cable 313 is applied with force to drive the first cable 311 to slide relative to the support tube 110 in a first direction through the crimping tube 312, because the first cable 311 is in contact with the steering structure 160, the moving direction of the portion of the first cable 311 located outside the receiving channel 115 is changed, that is, the first cable 311 located outside the receiving channel 115 moves in a second direction opposite to the first direction, thereby driving the actuating member 320 to slide in the second direction, the actuating member 320 is close to the jaw arm 210, and after the jaw arm 210 is pressed, closing the open jawarms 210.

Referring to fig. 9, in the present embodiment, the actuating member 320 is optionally configured as a sleeve, the sleeve is disposed outside the supporting tube 110, and the sleeve is configured to simultaneously drive the two forceps arms 210 to move when sliding relative to the supporting tube 110, so as to switch the two forceps heads 200 from the open state to the closed state.

Optionally, the sleeve is provided with two second through holes 321 and two inner concave portions 322, and the two inner concave portions 322 correspond to the two second through holes 321, respectively. The outer concave surface of the inner concave portion 322 forms a groove 3221, one end of the groove 3221 is communicated with the second through hole 321, and the other end of the groove 3221 extends to the end surface of the sleeve far away from the second through hole 321. The inner convex surface of the inner concave part 322 is in sliding fit with the avoiding groove 114 on the supporting tube 110, and the inner concave part 322 is in sliding fit with the avoiding groove 114, so that the inner concave part 322 not only plays a role of a guide sleeve, but also plays a role of limiting relative rotation of the sleeve and the supporting tube 110. The part of the first pulling cable 311 outside the receiving channel 115 penetrates out of the sleeve from the second through hole 321 and is located in the groove 3221, and the first pulling cable 311 is fixedly connected with the groove wall of the groove 3221. The first pulling cable 311 does not protrude out of the notch of the groove 3221, and the first pulling cable 311 is not easy to contact and rub with an endoscope channel and is not easy to damage the endoscope channel.

It should be noted that when the second cable 313 is pulled to drive the portion of the first cable 311 located in the receiving channel 115 to move along the first direction, the portion of the first cable 311 located outside the receiving channel 115 slides along the second direction, and drives the actuator 320 to slide along the second direction, and the actuator 320 is close to the forceps arm 210, so that the forceps arm 210 is switched from the initial open state to the closed state. When the external force is removed, the clamp arm 210 automatically opens under the action of the elastic force of the clamp arm 210 itself, the actuating member 320 is driven to move along the first direction, the portion of the first pulling cable 311 located in the accommodating channel 115 slides along the second direction, and the clamp arm 210 returns to the initial open state.

It will be appreciated that the actuator 320 is in the first position when the jawarms 210 are in the open position and the actuator 320 is in the second position when the jawarms 210 are in the closed position, and that two stops may be provided to limit the position of the actuator 320 in order to ensure that the first and second positions of the actuator 320 are stable.

For example, in order to ensure the accuracy of the first position of the actuating member 320, a side of the avoiding groove 114 away from the first end 111 of the supporting tube 110 is set to have a distance from the second end 112 of the supporting tube 110, a side of the avoiding groove 114 away from the first end 111 is a first abutting side 231, and when the actuating member 320 is at the first position, the inner concave portion 322 of the actuating member 320 abuts against the first abutting side 231, so as to limit the sliding of the actuating member 320 along the first direction. In order to ensure the accuracy of the second position of the actuator 320, the side of the insulating layer 230 disposed on the jawarm 210 close to the support tube 110 is set as a second abutting side 1141, and when the actuator 320 is at the second position, the end surface of the actuator 320 abuts against the second abutting side 1141, so as to limit the actuator 320 from sliding along the second direction. In other words, the initial position and the final position of the actuator 320 are determined, the stroke of the actuator 320 is determined, and the actuator 320 operates stably and reliably. Meanwhile, when the forceps head 200 is used for clamping tissues, the executing piece 320 cannot move continuously when the executing piece 320 moves to a position where the executing piece is abutted to the insulating layer 230, at the moment, an operator receives feedback that the executing piece 320 cannot move continuously, and the operator can clearly know that the forceps head 200 is clamped in place, so that the safety of the operation is improved.
