[0037] The present application is further described in detail below through the accompanying drawings and embodiments. Through these descriptions, the characteristics and advantages of the present application will become clearer and more specific.

[0038] The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise noted.

[0039] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The following discussion provides multiple embodiments of the present application. Although each embodiment represents a single combination of the application, different embodiments of the present application can be replaced or combined, so the present application can also be considered to include all possible combinations of the same and / or different embodiments recorded. Therefore, if one embodiment includes A, B, C, and another embodiment includes a combination of B and D, then the present application should also be considered to include an embodiment containing one or more of all other possible combinations of A, B, C, D, although the embodiment may not be clearly recorded in the following text. In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0040] like Figure 1 and Figure 2 As shown, the endoscopic anastomotic clip 100 provided in the embodiment of the first aspect of the present application includes: a suture belt 10, a locking belt 20, a locking member 30 and a puncture portion 40.

[0041] The two ends of the suture belt 10 are respectively provided with a connection area 11 , and a one-way clamping structure 12 is arranged in the connection area 11 .

[0042] The locking belt 20 includes a first arc segment 21 and a matching portion 22 located at both ends of the first arc segment 21. The matching portion 22 is provided with a mounting hole 23 and a matching hole 24. The two ends of the suture belt 10 pass through the two mounting holes 23 respectively, so that the partial endoscopic anastomotic clip 100 is annular. The suture belt 10 can slide in the mounting hole 23. The matching hole 24 extends along the radial direction of the mounting hole 23 and is connected to the mounting hole 23. The ring includes a circular ring, an elliptical ring, a square ring, etc., which are not listed here one by one. Those skilled in the art should understand that as long as the partial endoscopic anastomotic clip 100 forms a ring-shaped structure, it should be within the protection scope of this application.

[0043] The locking member 30 is fixed on the first arc segment 21. The locking member 30 includes a spring sheet 31. The spring sheet 31 is located at the end of the first arc segment 21 and in the matching hole 24. The spring sheet 31 can be engaged with the one-way clamping structure 12. The one-way clamping structure 12 slides relative to the locking member 30 and is engaged with the spring sheet 31 in one direction. Since the one-way clamping structures 12 are multiple and continuous, with the relative movement between the locking belt 20 and the suture belt 10, the locking belt 20 and the suture belt 10 are locked in multiple stages and stepwise. The locking effect between the locking belt 20 and the suture belt 10 is not affected by the amount of mucosal tissue sucked or pulled into the stapler, which avoids the situation that too much tissue cannot be locked and too little tissue cannot be locked, so that the suture belt 10 and the locking belt 20 are firmly connected together, ensuring the effective ligation of the diseased mucosal tissue by the endoscopic anastomosis clip 100, thereby ensuring the safe and effective treatment of the diseased mucosal tissue.

[0044] The puncture portion 40 is disposed on the inner side of the endoscopic anastomosis clip 100. In one embodiment of the present application, the puncture portion 40 is disposed on the suture belt 10, and / or the puncture portion 40 is disposed on the locking belt 20. The puncture portion 40 can press against the diseased mucosal tissue or penetrate into the diseased mucosal tissue to ensure that the endoscopic anastomosis clip 100 effectively ligates the diseased mucosal tissue, thereby ensuring safe and effective treatment of the diseased mucosal tissue.

[0045] The endoscopic anastomotic clip 100 provided in the present application has a spring piece 31 located in the matching hole 24. Even if the matching portion 22 wraps the spring piece 31, the above structure allows the matching portion 22 to have a certain length, thereby increasing the contact area between the suture belt 10 and the matching portion 22, so that the matching portion 22 can provide more stable support for the suture belt 10, and reduce the shaking or deviation of the suture belt 10 in the mounting hole 23, thereby improving the accuracy and reliability of the movement, and further ensuring that the suture belt 10 and the locking belt 20 slide relative to each other and are smooth during the tightening process without tilting or getting stuck, so that the endoscopic anastomotic clip 100 can suture the mucosal tissue more smoothly.

[0046] In addition, the endoscopic anastomotic clip 100 has a simple structure and involves a small number of parts, thereby reducing the difficulty of assembling the endoscopic anastomotic clip 100 and greatly reducing the difficulty and cost of processing and manufacturing the endoscopic anastomotic clip 100 .

[0047] In addition, the puncture portion 40 can be pressed against the diseased mucosal tissue or penetrate into the diseased mucosal tissue to ensure that the endoscopic anastomotic clip 100 effectively ligates the diseased mucosal tissue, thereby ensuring safe and effective treatment of the diseased mucosal tissue.

[0048] like Figure 3 and Figure 4As shown, in one embodiment of the present application, a cutout 25 is provided on the outer surface of the mating portion 22 away from the locking member 30, the cutout 25 is connected to the mounting hole 23, the cutout 25 extends along the axial direction of the mounting hole 23 and passes through the mating portion 22, a portion of the suture tape 10 protrudes from the cutout 25 or the portion of the suture tape 10 located at the cutout 25 is flush with the outer surface of the mating portion 22.

[0049] During the cooperation process of the endoscopic anastomotic clip 100, the suture belt 10 is fitted with the wall surface of the endoscopic stapler 200 through the incision 25. Since the suture belt 10 needs to move in the endoscopic stapler 200 and the wall surface of the endoscopic stapler 200 is fixed, the wall surface of the endoscopic stapler 200 can play a good limiting role on the suture belt 10, reducing the shaking or deviation of the suture belt 10 in the mounting hole 23, thereby improving the accuracy and reliability of the movement, thereby ensuring that the suture belt 10 and the locking belt 20 slide relative to each other and are smooth during the tightening process without tilting or getting stuck, so that the endoscopic anastomotic clip 100 can suture the mucosal tissue more smoothly.

[0050] like Figure 3 to Figure 4 As shown, in one embodiment of the present application, the suture belt 10 includes a second arc segment 13 and straight segments 14 located at both ends of the second arc segment 13 , and the connection area 11 is arranged on the straight segment 14 .

[0051] In the width direction of the straight segment 14 , the cross-sectional shape of the straight segment 14 is a polygon, and the shape of the mounting hole 23 matches the shape of the straight segment 14 .

[0052] The above-mentioned shape requirements for the straight segment 14 and the mounting hole 23 enable the straight segment 14 to have multiple planar contacts with the matching portion 22, so that the matching portion 22 can provide more contact points and support surfaces for the straight segment 14, so that the matching portion 22 can provide more stable support for the straight segment 14, reduce the shaking or deviation of the straight segment 14 in the mounting hole 23, thereby improving the accuracy and reliability of the movement, and further ensuring that the straight segment 14 and the locking belt 20 slide relative to each other and are smooth during the tightening process without tilting or getting stuck, so that the endoscopic anastomosis clip 100 can suture the mucosal tissue more smoothly.

[0053] like Figure 5 As shown, in a specific embodiment of the present application, in the axial direction of the mounting hole 23 , the length H2 of the matching portion 22 is not less than 3 mm.

[0054] The above parameter requirements ensure the contact area between the suture belt 10 and the matching part 22, so that the matching part 22 can provide more stable support for the suture belt 10, reduce the shaking or deviation of the suture belt 10 in the mounting hole 23, thereby improving the accuracy and reliability of the movement, and further ensuring that the suture belt 10 and the locking belt 20 slide relative to each other and are smooth during the tightening process without tilting or getting stuck, so that the endoscopic anastomosis clip 100 can suture the mucosal tissue more smoothly.

[0055] like Figure 5 As shown, in another specific embodiment of the present application, in the axial direction of the mounting hole 23 , the length H2 of the matching portion 22 is not less than one third of the length H1 of the straight section 14 .

[0056] The above parameter requirements ensure the contact area between the suture belt 10 and the matching part 22, so that the matching part 22 can provide more stable support for the suture belt 10, reduce the shaking or deviation of the suture belt 10 in the mounting hole 23, thereby improving the accuracy and reliability of the movement, and further ensuring that the suture belt 10 and the locking belt 20 slide relative to each other and are smooth during the tightening process without tilting or getting stuck, so that the endoscopic anastomosis clip 100 can suture the mucosal tissue more smoothly.

[0057] like Figure 5 As shown, in yet another specific embodiment of the present application, in the axial direction of the mounting hole 23 , the length H2 of the matching portion 22 is not greater than half of the length H1 of the straight section 14 .

[0058] Since the fitting portion 22 and the straight segment 14 can move relative to each other, if the length of the fitting portion 22 is too long, the length of the straight segment 14 will also be too long. On the one hand, this will cause the size of the endoscopic anastomotic clip 100 to increase and become unsuitable for the application scenario. On the other hand, after the endoscopic anastomotic clip 100 is tightened and shrunk, the straight segment 14 protrudes too much from the outer surface of the endoscopic suturer 200, resulting in scratches on the mucosal tissue. Therefore, the above-mentioned parameter restrictions make the length of the fitting portion 22 reasonable, thereby ensuring the safety of use and the stability of implementation of the endoscopic anastomotic clip 100.

[0059] like Figure 6 As shown, in one embodiment of the present application, the locking member 30 includes a connecting piece 32 and spring pieces 31 located at both ends of the locking member 30 , and the connecting piece 32 fits with the first arc segment 21 and is fixedly connected to the first arc segment 21 .

[0060] The connection area between the connecting piece 32 and the locking belt 20 is large, thereby ensuring the reliability of the connection between the lock buckle 33 and the locking belt 20, thereby reducing the probability of the lock buckle 33 falling off the locking belt 20, and ensuring the reliability of the use of the endoscopic anastomosis clip 100.

[0061] like Figure 7As shown, in one embodiment of the present application, the locking member 30 includes two locking buckles 33 .

[0062] The two lock buckles 33 are respectively located at two ends of the first arc segment 21 . The lock buckles 33 include a fixing portion 331 and a spring sheet 31 which are connected in sequence. The fixing portion 331 is fixedly connected to the first arc segment 21 .

[0063] The lock buckle 33 has a simple structure, and the matching structure can be assembled to the locking belt 20 by welding or fixing with a pin.

[0064] like Figure 8 and Fig. 9 As shown, the endoscopic suturing assembly provided by the embodiment of the second aspect of the present application includes an endoscopic stapler 200 and any one of the above-mentioned endoscopic anastomotic clips 100 , and the endoscopic anastomotic clip 100 is arranged on the endoscopic stapler 200 .

[0065] The endoscopic suturing assembly provided in the present application, the endoscopic suturing device 200 can smoothly release the endoscopic anastomotic clip 100, thereby ensuring that the released endoscopic anastomotic clip 100 is accurately ligated or sutured at the root of the diseased mucosal tissue; during the operation, the endoscopic anastomotic clip 100 firmly ligates the root of the diseased mucosal tissue, ensuring safe and effective treatment of the diseased mucosal tissue.

[0066] like Figure 8 and Fig. 9 As shown, in one embodiment of the present application, the endoscopic suturing device 200 includes: a main body 201 , a movable seat 203 , a transmission plate 204 , a rotating member 205 , a transmission rod 206 and a driving member 207 .

[0067] The main body 201 is provided with an extrusion seat 202 and a through hole passing therethrough, and the through hole is configured to cooperate with the endoscope 300 .

[0068] The moving seat 203 is installed on the main body 201 and can slide along a straight line relative to the main body 201 . The setting position of the moving seat 203 corresponds to the position of the pressing seat 202 , and there is a gap between the moving seat 203 and the pressing seat 202 .

[0069] The transmission plate 204 is disposed on the main body 201 and connected to the moving seat 203 . The transmission plate 204 can slide along a straight line relative to the main body 201 , and a first meshing tooth is disposed on the transmission plate 204 .

[0070] The rotating member 205 is disposed on the main body 201 and can rotate relative to the main body 201 . The rotating member 205 is provided with second meshing teeth, which mesh with the first meshing teeth.

[0071] One end of the transmission rod 206 is fixedly connected to the rotating member 205 .

[0072] The driving member 207 cooperates with the other end of the transmission rod 206 , and the driving member 207 is configured to drive the rotating member 205 to rotate relative to the main body 201 through the transmission rod 206 .

[0073] The endoscopic anastomotic clip 100 is disposed in the interval and can be squeezed and deformed by the moving seat 203 and the squeezing seat 202 to suture the diseased mucosal tissue.

[0074] After the endoscopic suturing assembly is extended into the human body, the diseased mucosal tissue is sucked or pulled into the endoscopic suturing device 200, so that the diseased mucosal tissue passes through the endoscopic anastomotic clip 100; then the driving member 207 is operated to control the rotating member 205 to rotate relative to the main body 201 through the transmission rod 206, and the rotating member 205 drives the transmission plate 204 to move through the cooperation of the first meshing teeth and the second meshing teeth, and the transmission plate 204 drives the extrusion seat 202 to move, so as to change the distance between the moving seat 203 and the extrusion seat 202. In this process, the moving seat 203 and the extrusion seat 202 are moved. 2. The endoscopic anastomosis clip 100 is squeezed together to fix the endoscopic anastomosis clip 100 on the root of the diseased mucosal tissue to suture the diseased mucosal tissue; in the above suturing process, since the extrusion seat 202 moves in a straight line, the force applied to the endoscopic anastomosis clip 100 is always in one direction, which ensures that the endoscopic anastomosis clip 100 is a translational movement without lateral displacement, so that the suturing position of the endoscopic anastomosis clip 100 remains unchanged, so that the endoscopic anastomosis clip 100 can accurately suture the diseased mucosal tissue, thereby ensuring the suturing, strength and precision of the product.

[0075] In addition, the rotating member 205, the transmission rod 206 and the driving member 207 are equivalent to levers. By reasonably setting the relative length between the rotating member 205 and the transmission rod 206, the relationship between the power arm and the resistance arm can be adjusted, so that when a small force is applied to the transmission rod 206 through the driving member 207, the force can be transmitted through the rotating member 205 and the transmission rod 206 to become a large force acting on the transmission plate 204, and transmitted to the movable seat 203, so that there can be a large supporting force between the movable seat 203 and the extrusion seat 202, so that when the endoscopic anastomotic clip 100 is blocked by ligating a harder diseased mucosal tissue, the endoscopic suture device 200 can provide a large enough force to make the endoscopic anastomotic clip 100 firmly ligated at the root of the diseased mucosal tissue, so as to ensure that the endoscopic anastomotic clip 100 effectively ligates the diseased mucosal tissue, thereby ensuring safe and effective treatment of the diseased mucosal tissue.

[0076] like Fig.10 As shown, in one embodiment of the present application, the movable seat 203 includes an extrusion portion 231 and connection portions 232 located at two ends of the extrusion portion 231 .

[0077] The connecting portion 232 extends along the sliding direction of the moving base 203 .

[0078] Part of the main body 201 is located between the two connecting parts 232 , and the connecting part 232 is connected to the main body 201 .

[0079] The portion of the suture band 10 of the endoscopic anastomotic clip 100 located at the cutout 25 of the matching portion 22 of the endoscopic anastomotic clip 100 contacts the connecting portion 232 .

[0080] During the use of the endoscopic anastomotic clip 100, the suture belt 10 is fitted with the wall surface of the connecting portion 232 through the incision 25. Since the suture belt 10 needs to move in the endoscopic stapler 200 and the wall surface of the connecting portion 232 is fixed, the wall surface of the connecting portion 232 can play a good limiting role on the suture belt 10, reducing the shaking or deviation of the suture belt 10 in the mounting hole 23, thereby improving the accuracy and reliability of the movement, and further ensuring that the suture belt 10 and the locking belt 20 slide relative to each other and are smooth during the tightening process without tilting or getting stuck, so that the endoscopic anastomotic clip 100 can suture the mucosal tissue more smoothly.

[0081] like Fig.11 and Fig.12 As shown, in one embodiment of the present application, the endoscopic suturing device 200 further includes: a treatment coil 208 , a push-pull member 209 and a sleeve 210 .

[0082] The treatment coil 208 is disposed in the through hole, and the treatment coil 208 is configured to be able to be wrapped around the diseased mucosal tissue.

[0083] One end of the push-pull member 209 is connected to the treatment coil 208 , and the other end of the push-pull member 209 passes through the main body 201 .

[0084] The sleeve 210 is sleeved on the push-pull member 209 , and the push-pull member 209 extends out of the sleeve 210 .

[0085] After the endoscopic suturing assembly is extended into the human body, the diseased mucosal tissue is sucked or pulled into the endoscopic suturing device 200, so that the diseased mucosal tissue passes through the endoscopic anastomotic clip 100 and the treatment coil 208 in sequence; then the driving member 207 is operated to control the rotating member 205 to rotate relative to the main body 201 through the transmission rod 206, and the rotating member 205 drives the transmission plate 204 to move through the cooperation of the first meshing teeth and the second meshing teeth, and the transmission plate 204 drives the extrusion seat 202 to move, so as to change the distance between the moving seat 203 and the extrusion seat 202. In this process, the moving seat 203 and the extrusion seat 202 jointly squeeze the endoscopic anastomotic clip 100, so that the endoscopic anastomotic clip 100 is closed. The endoscopic anastomosis clip 100 is fixed on the root of the diseased mucosal tissue; the push-pull member 209 is dragged, and the push-pull member 209 drives the treatment coil 208 to move relative to the sleeve 210, and the sleeve 210 can be pressed against the treatment coil 208 to tighten and shrink the treatment coil 208, and then the diseased mucosal tissue is removed through the treatment coil 208; during the operation, the endoscopic anastomosis clip 100 firmly ligates the root of the diseased mucosal tissue, thereby facilitating the removal of the diseased mucosal tissue by the loop treatment member. At the same time, the endoscopic anastomosis clip 100 can firmly suture the wound caused by the removal of the diseased mucosal tissue, thereby reducing the occurrence of postoperative complications.

[0086] In addition, the endoscopic stapler 200 can simultaneously achieve the excision of the diseased mucosal tissue and the suturing of the wound after excision, that is, one device can achieve both excision and suturing operations. On the one hand, it reduces the number of tools used in the operation and reduces the difficulty of the operation of excision of the diseased tissue. On the other hand, the operation is simple, thereby improving the comfort and efficiency of the product. The above treatment coil 208, push-pull member 209 and sleeve 210 are also suitable for use in other embodiments of the present technology, which are not listed here one by one.
