[0075] The technical solutions of the embodiments of the present application are described in detail below in conjunction with the accompanying drawings. The technical features involved in the different implementation modes of the present application described below can be combined with each other as long as there is no conflict between them.

[0076] For ease of understanding, the following Figures 1 to 33 The suturing device shown describes the specific structure of the simple endoscopic stapler releasing device.

[0077] like Figures 1 to 33 As shown, the simple endoscopic stapler releasing device 100 provided in the embodiment of the first aspect of the present application includes: a main body 10 , a movable seat 20 , a suturing assembly 30 , a rotating member 41 and a rotating control member 50 .

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

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

[0080] The suturing assembly 30 is disposed on the moving base 20 and is located in the space. The suturing assembly 30 is movable relative to the moving base 20 , and is configured to accommodate the staples 200 .

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

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

[0083] In the simple endoscopic stapler releasing device 100 provided in the present application, the rotating control member 50 directly drives the moving seat 20 via the rotating member 41. On the one hand, the force can be transmitted from the rotating 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 gap between components. When force is applied to the rotating control member 50, the moving seat 20 can respond more quickly and move relative to the main body 10 to achieve rapid force adjustment and control. On the other hand, the force transmission deviation caused by the cumulative errors of multiple components is reduced, so that the output force is more accurately in line with expectations, which is conducive to improving the control accuracy and work quality of the system.

[0084] In addition, the driving part of the simplified endoscopic stapler releasing device 100 only includes two parts: the rotating member 41 and the rotating control member 50. On the one hand, the layout of the product is more concise, the space occupied is small, and it is easy to install and maintain. On the other hand, the complexity and failure rate of the product are reduced, and the reliability and stability of the system are improved.

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

[0086] The locking member 61 is disposed on the movable seat 20 and can move relative to the movable seat 20 . The setting position of the locking member 61 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 stapler release device 100 enters the human body, the tissue is pulled between the suturing assembly 30 and the extrusion seat 11, and then the rotary control member 50 is operated to control the rotary member 41 to rotate relative to the main body 10, and the rotary member 41 drives the movable seat 20 to move, so as to change the distance between the movable seat 20 and the extrusion seat 11, so that the movable seat 20 and the extrusion seat 11 can squeeze and fix the tissue. In this process, the locking member 61 stops the suturing assembly 30 from moving relative to the movable seat 20. Then, the locking member 61 is controlled to separate from the suturing assembly 30 by the locking control member 62, and then the rotary control member 50 is continued to be operated to make the movable seat 20 continue to move, so as to push the staple 200 out of the suturing assembly 30. In this process, the needle pusher 25 on the movable seat 20 and the extrusion seat 11 jointly squeeze the staple 200, so that the staple 200 is ligated / sutured on the root of the tissue, so as to suture the tissue. In the above-mentioned tissue suturing process, the tissue is first squeezed and fixed by the squeezing action between the movable seat 20 and the suturing assembly 30 and the squeezing seat 11, and then the tissue is sutured by the stapler 200. On the one hand, it can effectively improve the accuracy and safety of the subsequent puncture, for example, avoiding bleeding during the puncture process to ensure that the stapler 200 smoothly sutures the tissue, thereby ensuring safe and effective treatment of the tissue. On the other hand, the above-mentioned operation requires a simple push and pull action, or at the same time, a simple torsion spring is used to assist in returning to the original position. For example, a return torsion spring is set between the rotating member 41 and the main body 10. There is no other complicated operation method, which reduces the difficulty of product operation, thereby effectively providing the product with comfort.

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

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

[0091] When the rotating member 41 drives the movable seat 20 to move, the setting of the limit member 80 limits the rotation angle of the rotating member 41, thereby preventing the movable seat 20 from escaping from the main body 10, that is, preventing the rotating member 41 from rotating too much and causing the movable seat 20 to escaping from the main body 10, thereby ensuring the reliability of the product.

[0092] like Figures 1 to 10 As shown, in one embodiment of the present application, the movable 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 located at the connection of the main body 10 . The setting position of the seat body 22 corresponds to the position of the extrusion seat 11 .

[0094] The two connecting parts 23 are respectively provided with first meshing teeth 21 .

[0095] There are two rotating members 41 , which are connected via a rotating rod 42 . The rotating rod 42 is disposed on the main body 10 and can rotate relative to the main body 10 . The two rotating members 41 are matched with the two connecting parts 23 respectively.

[0096] There are two rotating parts 41. During the process of driving the moving seat 20, the moving seat 20 can be subjected to uniform force, thereby reducing local stress concentration, and can reduce deformation and jamming caused by uneven stress, thereby enhancing the stability of the structure and the smoothness of movement.

[0097] like Fig.12 As shown, in another embodiment of the present application, the movable 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 located at the connection of the main body 10 . The setting position of the seat body 22 corresponds to the position of the extrusion seat 11 .

[0099] A first meshing tooth 21 is disposed on one connecting portion 23 .

[0100] The number of the rotating member 41 is one, which makes the structure of the product simpler while ensuring satisfactory effects, thereby reducing the complexity of the product and the failure rate.

[0101] like Fig.11 As shown, in one embodiment of the present application, the suturing 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 movable seat 20, and the other part of the fixing frame 32 is located in the interval. The fixing frame 32 has a receiving portion 36, and the receiving portion 36 is configured to receive the staples 200. A needle outlet 37 is provided on the side wall of the receiving portion 36, and the setting position of the needle pusher 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 base 20 .

[0104] After the fixed frame 32 presses against the tissue, the movable seat 20 is controlled to slide relative to the main body 10, and the movable seat 20 pushes the staple 200 out of the fixed frame 32 from the needle outlet 37, and the first puncture portion penetrates the tissue, and the first puncture portion abuts against the pressing seat 11. After that, the movable seat 20 continues to push the staple 200, so that the first puncture portion is bent and pressed against the tissue, so that the staple 200 tightens the tissue to ensure effective treatment of the tissue. The above-mentioned suture piece has a simple structure and is easy to process.

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

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

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

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

[0109] A second elastic member is disposed 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 box is basically the same as above. After a staple is sutured on the tissue, the distance between the movable seat and the extrusion seat becomes larger, and the needle pusher member exits the needle box. At the same time, the fixed frame is gradually restored to its initial position under the reaction force of the first elastic member. After the needle pusher member completely exits the needle box, the next staple is moved up and located between the needle outlet and the needle pusher member under the action of the second elastic member. After that, the distance between the movable seat and the extrusion seat is controlled to become smaller, so that the staple is pushed out of the fixed 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 tissues, reduce the number of times staples are installed, and thus improve the use efficiency of the product.

[0111] like Fig.11 As shown, in one embodiment of the present application, the receiving portion 36 is an accommodating space, and the accommodating space is configured to accommodate the staples 200 .

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

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

[0114] The anastomotic staple group is arranged in the accommodating space of the simple endoscopic anastomotic 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 on the tissue, the distance between the movable seat 20 and the extrusion seat 11 becomes larger, and the needle pusher 25 withdraws from the accommodation space. At the same time, the fixing frame 32 is gradually restored to the initial position under the reaction force of the first elastic member 33. After the needle pusher 25 completely withdraws from the accommodation space, the next staple 200 is moved up and located between the needle outlet 37 and the needle pusher 25 under the action of the second elastic member 34. After that, the distance between the movable seat 20 and the extrusion seat 11 is controlled to become smaller, so that the staple 200 is pushed out of the fixing frame 32 from the needle outlet 37 and sutured on the tissue. And so on, the staples 200 are gradually released. The above structure can realize continuous suturing of tissues, reduce the number of times the staples 200 are installed, and thus improve the use efficiency of the product.

[0116] like Fig.11 As shown, in one embodiment of the present application, the suturing assembly 30 further includes: a guide post 35 .

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

[0118] The setting of the guide column 35 makes the elastic deformation process of the first elastic member 33 relatively more uniform, so that the force transmission is more stable, and the fixing frame 32 is prevented from tilting or falling out of the fixing hole 24 during movement, so as to ensure the smooth puncture and bending suturing of the staples 200.

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

[0120] In the first step, the staples 200 are placed into the suturing assembly 30 .

[0121] In the second step, the simple endoscopic stapler releasing device 100 is mounted on the front end of the endoscope 300, and then the simple endoscopic stapler releasing device 100 is inserted into the surgical operation site in the human body together with the endoscope 300 through the natural cavity of the human body.

[0122] In the third step, the front end of the simple endoscopic stapler releasing device 100 is aligned with the tissue to be sutured, and the tissue is clamped by an endoscopic clamp or an endoscopic forceps and pulled between the suture assembly 30 and the extrusion seat 11, such as Figures 3 to 10As shown, the rotary control member 50 is then operated to control the rotary member 41 to rotate relative to the main body 10. The rotary member 41 drives the movable seat 20 to move through the cooperation of the first meshing tooth 21 and the second meshing tooth 411, so that the distance between the movable seat 20 and the extrusion seat 11 becomes smaller. During this process, the fixed frame 32 moves in the opposite direction relative to the movement of the movable seat 20. During the movement, the staple 200 that contacts the needle pusher 25 is impacted by the needle pusher 25 and pushed out of the suturing assembly 30, and is squeezed by the front extrusion seat 11, so that the staple 200 passes through the tissue and then bends, thereby being ligated / sutured on the root of the tissue to suture the tissue.

[0123] The fourth step is to operate the rotary control member 50 in reverse to control the rotary member 41 to rotate in the opposite direction relative to the main body 10 after suturing the tissue. The rotary member 41 drives the reverse movable seat 20 to move through the cooperation of the first meshing tooth 21 and the second meshing tooth 411, so that the distance between the movable seat 20 and the extrusion seat 11 becomes larger. During this process, the fixed frame 32 moves in the opposite direction relative to the movable seat 20, and the needle pusher 25 gradually withdraws from the suturing assembly 30 to make room for installing the stapler 200, in preparation for the next suturing assembly.

[0134] After the simple endoscopic stapler release device 100 enters the human body, the tissue is pulled between the suturing assembly 30 and the extrusion seat 11, and then the rotary control member 50 is operated to control the rotary member 41 to rotate relative to the main body 10, and the rotary member 41 drives the extrusion seat 11 to move, so as 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 block 612 is controlled to separate from the suturing assembly 30 by the locking control member 62, and then the rotary control member 50 is continued to be operated to make the moving seat 20 continue to move, so as to push the staple 200 out of the suturing assembly 30. In this process, the moving seat 20 and the extrusion seat 11 jointly squeeze the staple 200, so that the staple 200 is ligated / sutured on the root of the tissue to suture the tissue. In addition, the locking block 612 has a simple structure and is easy to manufacture.

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

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

Specifically, the locking member 61 can be pushed away from the moving direction of the moving seat 20 , thereby being unlocked to allow the suturing assembly 30 to move smoothly.

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

[0141] After the simple endoscopic stapler release device 100 enters the human body, the tissue is pulled between the suturing assembly 30 and the extrusion seat 11, and then the rotary control member 50 is operated to control the rotating member 41 to rotate relative to the main body 10, and the rotating member 41 drives the extrusion seat 11 to move, so as 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 force applied to the rotary control member is increased, so that the second inclined surface 613 on the locking member 61 is squeezed and slid on the first inclined surface 31, similar to the mutual squeezing effect between the wedge blocks, so that the locking member 61 is separated from the suturing assembly 30. In this process, the suturing assembly 30 squeezes the spring sheet 621, so that the spring sheet 621 accumulates force, and finally, the staple 200 is pushed out of the suturing assembly 30, and at the same time, the moving seat 20 and the extrusion seat 11 jointly squeeze the staple 200, so that the staple 200 is ligated / sutured on the root of the tissue to suture the tissue.
