[0075] The technical solutions of the embodiments of the present application are described in detail below in conjunction with the drawings. The technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0076] For the convenience of understanding, the following uses Figures 1 to 33 the shown suture device to elaborate on the specific structure of the simple endoscopic anastomosis nail release device.

[0077] AsFigures 1 to 33 As shown in the figure, the simple endoscopic staple release device 100 provided by the embodiment of the first aspect of the present application includes: a main body 10, a moving seat 20, a suturing assembly 30, a rotating member 41, and a rotation control member 50.

[0078] An extrusion seat 11 and a through hole 12 penetrating the main body 10 are provided on the main body 10, and the through hole 12 is configured to cooperate with the endoscope 300.

[0079] The moving seat 20 is installed on the main body 10 and can slide linearly relative to the main body 10. The setting position of the moving seat 20 corresponds to the position of the extrusion seat 11, and there is a gap between the moving seat 20 and the extrusion seat 11. A first engaging tooth 21 is provided on the moving seat 20.

[0080] The suturing assembly 30 is arranged on the moving seat 20 and is located within the gap. The suturing assembly 30 can move relative to the moving seat 20 and is configured to accommodate staples 200.

[0081] The rotating member 41 is arranged on the main body 10 and can rotate relative to the main body 10. A second engaging tooth 411 meshing with the first engaging tooth 21 is provided on the rotating member 41.

[0082] The rotation control member 50 is connected to the rotating member 41 and is configured to drive the rotating member 41 to rotate relative to the main body 10.

[0083] In the simple endoscopic staple release device 100 provided by the present application, the rotation control member 50 directly drives the moving seat 20 through the rotating member 41. On the one hand, the force can be transmitted from the rotation control member 50 to the moving seat 20 more directly and efficiently, reducing the attenuation of the force caused by factors such as friction and clearance between components. And when a force is applied to the rotation control member 50, the moving seat 20 can respond more quickly, move relative to the main body 10, and achieve rapid force adjustment and control. On the other hand, the force transmission deviation caused by the cumulative error of multiple components is reduced, making the output force more accurately meet the expectation, which is beneficial to improving the control accuracy and working quality of the system.

[0084] In addition, the driving part of the simple endoscopic staple release device 100 only includes two components, namely the rotating member 41 and the rotation control member 50. On the one hand, it makes the layout of the product more concise, occupies less space, and is easy to install and maintain. On the other hand, it reduces the complexity and failure rate of the product, and improves the reliability and stability of the system.

[0085] As Figures 13 to 33 shown, in an embodiment of the present application, the simple endoscopic staple release device 100 further includes: a locking member 61 and a locking control member 62.

[0086] The locking member 61 is disposed on the moving seat 20 and can move relative to the moving seat 20. The position where the locking member 61 is disposed corresponds to the position of the suturing assembly 30, and the locking member 61 can interfere with the suturing assembly 30.

[0087] The locking control member 62 is connected to the locking member 61, and the locking control member 62 is configured to control the locking member 61 to interfere with or separate from the suturing assembly 30.

[0088] After the simple endoscopic anastomosis staple releasing device 100 enters the human body, the tissue is pulled between the suturing assembly 30 and the pressing seat 11. Then, the rotation control member 50 is operated to control the rotating member 41 to rotate relative to the main body 10. The rotating member 41 drives the moving seat 20 to move, so as to change the distance between the moving seat 20 and the pressing seat 11, so that the moving seat 20 and the pressing seat 11 squeeze and fix the tissue. During this process, the locking member 61 stops the suturing assembly 30 from moving relative to the moving seat 20. Then, the locking member 61 is controlled by the locking control member 62 to separate from the suturing assembly 30. Then, the rotation control member 50 is continuously operated to make the moving seat 20 continue to move, so as to push the anastomosis staple 200 out of the suturing assembly 30. During this process, the pusher member 25 on the moving seat 20 and the pressing seat 11 jointly squeeze the anastomosis staple 200, so that the anastomosis staple 200 is looped / sutured on the root of the tissue to suture the tissue. During the above tissue suturing process, the tissue is first squeezed and fixed by the squeezing action between the moving seat 20, the suturing assembly 30 and the pressing seat 11, and then the tissue is sutured by the anastomosis staple 200. On the one hand, the accuracy and safety of the subsequent puncture can be effectively improved. For example, bleeding during the puncture process can be avoided to ensure that the anastomosis staple 200 sutures the tissue smoothly, thereby ensuring safe and effective treatment of the tissue. On the other hand, the above operations only require simple pushing and pulling actions, or are assisted by a simple torsion spring for return at the same time. For example, a return torsion spring is provided between the rotating member 41 and the main body 10, without complex other operation methods, reducing the operation difficulty of the product, thereby effectively improving the use comfort of the product.

[0089] As Figures 1 to 33 shown, in an embodiment of the present application, the simple endoscopic anastomosis staple releasing device 100 further includes: a limiting member 80.

[0090] The limiting member 80 is disposed on the outer surface of the main body 10 and is located on the rotation path of the rotating member 41, and the rotating member 41 can interfere with the limiting member 80.

[0091] During the process of the rotating member 41 driving the moving seat 20 to move, the setting of the limiting member 80 limits the rotation angle of the rotating member 41, thereby avoiding the situation that the moving seat 20 disengages from the main body 10, that is, avoiding the situation that the moving seat 20 disengages from the main body 10 due to the over-large rotation angle of the rotating member 41, ensuring the use reliability of the product.

[0092] As Figures 1 to 10 shown, in an embodiment of the present application, the moving seat 20 includes a seat body 22 and two connecting parts 23.

[0093] The two connecting parts 23 are symmetrically arranged on both sides of the seat body 22 and are connected to the main body 10. The setting position of the seat body 22 corresponds to the position of the extrusion seat 11.

[0094] First engaging teeth 21 are respectively arranged on the two connecting parts 23.

[0095] The number of the rotating parts 41 is two. The two rotating parts 41 are connected by a rotating rod 42. The rotating rod 42 is arranged on the main body 10 and can rotate relative to the main body 10. The two rotating parts 41 are respectively matched with the two connecting parts 23.

[0096] The number of the rotating parts 41 is two. During the process of driving the moving seat 20, the moving seat 20 can be uniformly stressed, thereby reducing local stress concentration, reducing deformation and jamming caused by uneven stress, and further enhancing the structural stability and moving smoothness.

[0097] As Figure 12 shown, in another embodiment of the present application, the moving seat 20 includes a seat body 22 and two connecting parts 23.

[0098] The two connecting parts 23 are symmetrically arranged on both sides of the seat body 22 and are connected to the main body 10. The setting position of the seat body 22 corresponds to the position of the extrusion seat 11.

[0099] A first engaging tooth 21 is arranged on one connecting part 23.

[0100] The number of the rotating parts 41 is one. On the premise of ensuring satisfactory effects, the structure of the product is made simpler, thereby reducing the complexity and failure rate of the product.

[0101] As Figure 11 shown, in an embodiment of the present application, the suture assembly 30 includes: a fixing frame 32 and a first elastic member 33.

[0102] Part of the fixing frame 32 is located in the fixing hole 24 and can slide relative to the moving seat 20. Another part of the fixing frame 32 is located in the space. The fixing frame 32 has a receiving portion 36 which is configured to receive the staples 200. A needle outlet 37 is arranged on the side wall of the receiving portion 36. The setting position of the needle pushing member 25 corresponds to the position of the needle outlet 37.

[0103] The first elastic member 33 is supported between the fixing frame 32 and the moving seat 20.

[0104] After the fixing frame 32 presses against the tissue, the moving seat 20 is then controlled to slide relative to the main body 10. The moving seat 20 pushes the staple 200 out of the needle outlet 37 of the fixing frame 32. The first puncturing part penetrates the tissue and abuts against the pressing seat 11. After that, the moving seat 20 continues to push the staple 200, causing the first puncturing part to bend and press against the tissue, so that the staple 200 tightens the tissue, thus ensuring effective treatment of the tissue. The structure of the above suture is simple and easy to process.

[0105] In an embodiment of the present application, the simple endoscopic staple releasing device further includes: a needle cartridge and a second elastic member.

[0106] On the needle cartridge mounting and accommodating portion, the needle cartridge has an accommodating cavity with one end open. The setting position of the needle cartridge corresponds to the position of the fixing hole, and the needle cartridge is configured to accommodate staples.

[0107] In a specific embodiment of the present application, the number of staples is multiple, and the multiple stacked staples form a staple group.

[0108] The staple group is arranged in the needle cartridge of the simple endoscopic staple releasing device.

[0109] A second elastic member is arranged on the bottom wall of the accommodating space, and the second elastic member is configured to support the staples.

[0110] The operation process of pushing a staple out of the needle cartridge is basically the same as above. After a staple is sutured on the tissue, the distance between the moving seat and the pressing seat is increased. At this time, the needle pushing member exits the needle cartridge. At the same time, under the reaction force of the first elastic member, the fixing frame gradually returns to its initial position. After the needle pushing member completely exits the needle cartridge, under the action of the second elastic member, the next staple moves up and is located between the needle outlet and the needle pushing member. Then, the distance between the moving seat and the pressing seat is controlled to decrease, so that the staple is pushed out of the fixing frame from the needle outlet and sutured on the tissue. And so on, the staples are gradually released. The above structure can realize continuous suturing of the tissue, reduce the number of times of installing staples, and thus improve the use efficiency of the product.

[0111] As Figure 11 shown, in an embodiment of the present application, the accommodating portion 36 is an accommodating space, and the accommodating space is configured to accommodate the staple 200.

[0112] A second elastic member 34 is arranged on the bottom wall of the accommodating space, and the second elastic member 34 is configured to support the staple 200.

[0113] In a specific embodiment of the present application, the number of staples is multiple, and the multiple stacked staples form a staple group.

[0114] The staple group is arranged in the accommodation space of the simple endoscopic staple releasing device.

[0115] The operation process of pushing a staple 200 out of the accommodation space is basically the same as above. After a staple 200 is sutured to the tissue, the distance between the moving seat 20 and the pressing seat 11 is increased. At this time, the pushing needle member 25 exits the accommodation space. At the same time, under the reaction force of the first elastic member 33, the fixing frame 32 gradually returns to the initial position. After the pushing needle member 25 completely exits the accommodation space, under the action of the second elastic member 34, the next staple 200 moves upward and is located between the needle outlet 37 and the pushing needle member 25. Then, the distance between the moving seat 20 and the pressing seat 11 is controlled to decrease, so that the staple 200 is pushed out of the fixing frame 32 from the needle outlet 37 and sutured to the tissue. And so on, the staples 200 are gradually released. The above structure can realize continuous suturing of the tissue, reduce the number of times of installing the staples 200, and thus improve the use efficiency of the product.

[0116] As Figure 11 shown, in an embodiment of the present application, the suturing assembly 30 further includes: a guiding column 35.

[0117] One end of the guiding column 35 is connected to the fixing frame 32, the other end of the guiding column 35 passes through the moving seat 20, and the first elastic member 33 is sleeved on the guiding column 35 and supported between the fixing frame 32 and the moving seat 20.

[0118] The arrangement of the guiding column 35 makes the elastic deformation process of the first elastic member 33 relatively more uniform, so that the force transmission is more stable, avoiding the fixing frame 32 from tilting sideways or disengaging from the fixing hole 24 during the movement, to ensure the smooth puncture and bending suturing of the staple 200.

[0119] The specific operation of the simple endoscopic staple releasing device 100 is as follows:

[0120] The first step is to place the staple 200 into the suturing assembly 30.

[0121] The second step is to sleeve the simple endoscopic staple releasing device 100 on the front end of the endoscope 300. Then, the simple endoscopic staple releasing device 100 is passed through the natural body cavity of the human body together with the endoscope 300 into the surgical operation site in the human body.

[0122] The third step is to align the front end of the simple endoscopic staple releasing device 100 with the tissue to be sutured. By using existing technologies such as endoscopic clips or endoscopic forceps, the tissue is clamped and pulled between the suturing assembly 30 and the pressing seat 11. As Figures 3 to 10As shown, then operate the rotation control member 50 to control the rotation of the rotating member 41 relative to the main body 10. The rotating member 41 drives the movement of the moving seat 20 through the cooperation of the first engaging teeth 21 and the second engaging teeth 411, so that the distance between the moving seat 20 and the extrusion seat 11 becomes smaller. During this process, the fixing frame 32 moves in the opposite direction relative to the moving seat 20. During the movement, the anastomosis staple 200 in contact with the needle pushing member 25 is pushed out of the suture assembly 30 by the impact of the needle pushing member 25, and is extruded by the front extrusion seat 11 in front, so that the anastomosis staple 200 bends after passing through the tissue, and thus is ligated / sutured to the root of the tissue to suture the tissue.

[0123] Fourth step, after suturing the tissue, operate the rotation control member 50 in the reverse direction to control the reverse rotation of the rotating member 41 relative to the main body 10. The rotating member 41 drives the reverse movement of the moving seat 20 through the cooperation of the first engaging teeth 21 and the second engaging teeth 411, so that the distance between the moving seat 20 and the extrusion seat 11 becomes larger. During this process, the fixing frame 32 moves in the opposite direction relative to the moving seat 20, and the needle pushing member 25 gradually withdraws from the suture assembly 30 to create space for installing the anastomosis staple 200 and prepare for the next suture assembly.

[0124] The following specifically describes several embodiments of the locking member in conjunction with the accompanying drawings.

[0125] Embodiment 1

[0126] As Figures 13 to 21 shown, the locking member 61 is: a locking plate 611.

[0127] The locking plate 611 is arranged on the moving seat 20 and can move axially along the through hole 12 relative to the moving seat 20. The locking plate 611 is connected to the locking control member 62 and can interfere with the suture assembly 30.

[0128] After the simple endoscopic anastomosis staple releasing device 100 enters the human body, the tissue is pulled into the space between the suture assembly 30 and the extrusion seat 11. Then, operate the rotation control member 50 to control the rotation of the rotating member 41 relative to the main body 10. The rotating member 41 drives the movement of the extrusion seat 11 to change the distance between the moving seat 20 and the extrusion seat 11, so that the moving seat 20 and the extrusion seat 11 clamp and fix the tissue. Then, control the locking plate 611 to separate from the suture assembly 30 through the locking control member 62. Then, continue to operate the rotation control member 50 to make the moving seat 20 continue to move to push the anastomosis staple 200 out of the suture assembly 30. During this process, the moving seat 20 and the extrusion seat 11 jointly extrude the anastomosis staple 200, so that the anastomosis staple 200 is ligated / sutured to the root of the tissue to suture the tissue. In addition, the structure of the locking plate 611 is simple and easy to manufacture.

[0129] In one embodiment of the present application, the simple endoscopic staple releasing device 100 further includes an elastic reset member 70, and the elastic reset member 70 is respectively connected to the locking plate 611 and the moving seat 20.

[0130] When the locking plate 611 is separated from the suturing assembly 30, the elastic reset member 70 stores energy. During the interference process between the locking plate 611 and the suturing assembly 30, the elastic reset member 70 releases the stored force, which helps the locking plate 611 return to the initial position to interfere with the suturing assembly 30, ensuring the reliability of the operation.

[0131] Embodiment Two

[0132] As Figures 22 to 30 shown, the locking member 61 is a locking block 612.

[0133] The locking block 612 is arranged on the moving seat 20 and can rotate relative to the moving seat 20. The locking block 612 is connected to the locking control member 62 and can interfere with the suturing assembly 30.

[0134] After the simple endoscopic staple releasing device 100 enters the human body, the tissue is pulled between the suturing assembly 30 and the extrusion seat 11. Then, the rotation control member 50 is operated to control the relative rotation of the rotating member 41 with respect to the main body 10. The rotating member 41 drives the movement of the extrusion seat 11 to change the distance between the moving seat 20 and the extrusion seat 11, so that the moving seat 20 and the extrusion seat 11 clamp and fix the tissue. Then, the locking control member 62 is used to control the separation of the locking block 612 from the suturing assembly 30. After that, the rotation control member 50 is continuously operated to make the moving seat 20 continue to move, so as to push the staple 200 out of the suturing assembly 30. During this process, the moving seat 20 and the extrusion seat 11 jointly extrude the staple 200, so that the staple 200 is ligated / sutured to the root of the tissue to suture the tissue. In addition, the structure of the locking block 612 is simple and easy to manufacture.

[0135] In one embodiment of the present application, the simple endoscopic staple releasing device 100 further includes an elastic reset member 70, and the elastic reset member 70 is respectively connected to the locking block 612 and the moving seat 20.

[0136] When the locking plate 611 is separated from the suturing assembly 30, the elastic reset member 70 stores energy. During the interference process between the locking plate 611 and the suturing assembly 30, the elastic reset member 70 releases the stored force, which helps the locking plate 611 return to the initial position to interfere with the suturing assembly 30, ensuring the reliability of the operation.

[0137] Embodiment Three

[0138] As Figures 31 to 30 shown, a first inclined surface 31 is provided on the suturing assembly 30.

[0139] The locking member 61 is provided with a second inclined surface 613 that cooperates with the first inclined surface 31. The locking member 61 can move along the moving direction of the moving seat 20. Specifically, the locking member 61 can be pushed away deviating from the moving direction of the moving seat 20, so as to be unlocked to allow the suture assembly 30 to move smoothly.

[0140] The locking control member 62 is a spring piece 621, and the spring piece 621 is supported between the locking member 61 and the moving seat 20. The shape of the spring piece 621 is "V" shape, wavy shape, etc. As long as it can meet the use requirements, the shape of the spring piece 621 is not limited here.

[0141] After the simple endoscopic anastomosis nail releasing device 100 enters the human body, the tissue is pulled into the space between the suture assembly 30 and the pressing seat 11. Then, the rotation control member 50 is operated to control the relative rotation of the rotating member 41 with respect to the main body 10. The rotating member 41 drives the pressing seat 11 to move, so as to change the distance between the moving seat 20 and the pressing seat 11, so that the moving seat 20 and the pressing seat 11 clamp and fix the tissue. Then, the force applied to the rotation control member is increased, so that the second inclined surface 613 on the locking member 61 slides by extrusion on the first inclined surface 31, similar to the mutual extrusion effect between wedge blocks, so that the locking member 61 is separated from the suture assembly 30. During this process, the suture assembly 30 presses the spring piece 621 to store energy in the spring piece 621. Finally, the anastomosis nail 200 is pushed out of the suture assembly 30. At the same time, the moving seat 20 and the pressing seat 11 jointly press the anastomosis nail 200, so that the anastomosis nail 200 is ligated / sutured at the root of the tissue to suture the tissue.

[0142] The suture device provided by the embodiment of the second aspect of the present application includes the above-mentioned simple endoscopic anastomosis nail releasing device 100 and anastomosis nail 200.

[0143] The anastomosis nail 200 is arranged in the suture assembly 30 of the simple endoscopic anastomosis nail releasing device 100, and the anastomosis nail 200 can be extruded and deformed. In an embodiment of the present application, the number of anastomosis nails is multiple, and the multiple anastomosis nails are stacked to form an anastomosis nail group; the anastomosis nail group is arranged in the needle cartridge of the simple endoscopic anastomosis nail releasing device. In another embodiment of the present application, the number of anastomosis nails is multiple, and the multiple anastomosis nails are stacked to form an anastomosis nail group; the anastomosis nail group is arranged in the accommodation space of the simple endoscopic anastomosis nail releasing device.

[0144] The suture device provided by the present application can effectively improve the accuracy and reliability of suturing tissues, so as to ensure the effective suturing of the tissue by the anastomosis nail 200, thereby ensuring the effective treatment of the tissue. In addition, the structure of the suture device is simple, the layout of the product is more concise, and the failure rate of the product is relatively low.
