[0062] 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.

[0063] For ease of understanding, the following Figures 1 to 17 The suturing device shown describes the specific structure of the staple releasing device.

[0064] like Figures 1 to 17 As shown, the stapler releasing device provided by the embodiment of the first aspect of the present application includes: a main body 10 , a movable seat 20 , a driving assembly 30 , a needle pushing plate 50 , a driving member 60 and a control member 70 .

[0065] 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 100 .

[0066] The movable seat 20 is installed on the main body 10, and 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 and / or the extrusion seat 11 can slide in a straight line relative to the main body 10. An installation space 21 is set on the movable seat 20, and the installation space 21 is configured to accommodate the staples 40.

[0067] The driving assembly 30 is disposed on the main body 10 and connected to the moving base 20 . The driving assembly 30 is configured to drive the moving base 20 to move relative to the main body 10 .

[0068] The needle pushing plate 50 is disposed on the movable seat 20 and can be moved relative to the movable seat 20 to be inserted into the installation space 21 . The needle pushing plate 50 is configured to push the staples 40 out of the installation space 21 .

[0069] The driving member 60 is disposed on the moving seat 20 and can move relative to the moving seat 20 . The driving member 60 is connected to the pin-pushing plate 50 . The driving member 60 is configured to drive the pin-pushing plate 50 to move relative to the moving seat 20 .

[0070] The control member 70 is connected to the driving member 60 , and the control member 70 is configured to drive the driving member 60 to move relative to the moving base 20 .

[0071] The stapler releasing device provided in the present application first fixes the mucosal tissue through the action of the squeezing seat 11 and the moving seat 20, and then sutures the mucosal tissue through the stapler 40. The above suturing process includes two operations. On the one hand, in the process of fixing the mucosal tissue, multiple adjustments can be made until the squeezing seat 11 and the moving seat 20 can accurately and firmly fix the mucosal tissue, thereby ensuring the accuracy of the subsequent puncture of the mucosal tissue by the stapler 40; on the other hand, the squeezing seat 11 and the moving seat 20 jointly squeeze the blood vessels inside the mucosal tissue, which has a certain hemostatic effect on the blood vessels, reduces the probability of bleeding in the subsequent process of the stapler 40 puncturing the mucosal tissue, and can effectively improve the safety of the product; therefore, the stapler releasing device can effectively suture the mucosal tissue, thereby ensuring safe and effective treatment of the mucosal tissue.

[0072] In addition, the operator of the stapler release device only needs to perform simple push and pull movements without any other complicated operation methods, which reduces the operating difficulty of the product.

[0073] The specific operation of the stapler release device is as follows:

[0074] In the first step, the stapler 40 is installed in the installation space 21, and the stapler releasing device is mounted on the front end of the endoscope 100. Then, the stapler releasing device is introduced into the surgical operation site in the human body together with the endoscope 100.

[0075] In the second step, the driving component 30 drives the movable seat 20 to rotate in the direction away from the extrusion seat 11, so that the distance between the movable seat 20 and the extrusion seat 11 is increased, and then, the mucosal tissue to be punctured is clamped or anchored by an existing endoscopic instrument such as an endoscopic forceps, and then pulled into the space between the movable seat 20 and the extrusion seat 11; thereafter, the driving device drives the component 30 to rotate the movable seat 20 in the direction close to the extrusion seat 11, so that the movable seat 20 and the extrusion part work to extrude and fix the mucosal tissue; if it is observed through the endoscope 100 that the clamping position of the movable seat 20 and the extrusion part on the mucosal tissue is incorrect, the above operation can be repeated multiple times so that the extrusion seat 11 and the movable seat 20 can accurately and firmly fix the mucosal tissue.

[0076] In the third step, the driving member 60 is controlled by the control member 70 to move relative to the movable seat 20. The driving member 60 drives the push pin plate 50 to move relative to the movable seat 20, so that the push pin plate 50 pushes the staple 40 out of the installation space 21 and penetrates the mucosal tissue. The staple 40 is squeezed and deformed by the squeezing seat 11 to suture the mucosal tissue.

[0077] In the fourth step, the control member 70 controls the driving member 60 to move in the opposite direction relative to the movable seat 20, and the driving member 60 drives the needle push plate 50 to withdraw from the installation space 21 to free up space for installing the stapler 40, so as to prepare for the second puncture and suturing.

[0078] like Figures 1 to 17 As shown, in some embodiments of the present application, the movable seat 20 is provided with an avoidance hole 22 penetrating therethrough, the avoidance hole 22 is communicated with the installation space 21 , and the setting position of the avoidance hole 22 corresponds to the position of the through hole 12 .

[0079] When the product is inserted into the human body, the endoscope 100 can see the situation of the human body components at the front end of the product through the avoidance hole 22, avoiding blind spots and potential dangers, so that the product can reach the position that needs to be sutured more accurately.

[0080] like Figure 7 As shown, in some embodiments of the present application, a side wall of the installation space 21 is a cover plate 23 , and the cover plate 23 is detachably connected to the movable seat 20 .

[0081] When the staples 40 need to be installed in the installation space 21, the cover plate 23 is removed, and then the staples 40 are installed in the installation space 21, and then the cover plate 23 is fixedly connected to the movable seat 20. The above structure facilitates the installation of the staples 40. In the process of installing the staples 40, the staples 40 can be installed in the installation space 21 one by one in multiple times, or multiple staples 40 can be installed in the installation space 21 together as a component.

[0082] In addition, the installation space 21 may be provided inside the movable base 20 , or may be other structures fixed on the movable base 20 and enclosed together with the movable base 20 .

[0083] like Figures 1 to 17 As shown, in some embodiments of the present application, a receiving space 24 is formed on the movable seat 20 , and the driving member 60 is disposed in the receiving space 24 .

[0084] The setting of the accommodating space 24 allows the space occupied by the driving member 60 and the movable seat 20 to overlap, thereby reducing the space occupied by the driving member 60 and making the overall volume of the product smaller, so that the stapler releasing device can be smoothly inserted into or withdrawn from the human body, thereby improving the comfort of the product and reducing the risk of scratching the mucosal tissue during the process of the device entering and withdrawing from the human body's lumen.

[0085] like Figures 1 to 17 As shown, in some embodiments of the present application, a guide groove 25 is provided on the movable seat 20 , and the push-pin plate 50 is inserted into the guide groove 25 and can move in the guide groove 25 .

[0086] The setting of the guide groove 25 guides the movement trajectory of the push pin plate 50, which helps the push pin plate 50 move more smoothly, thereby reducing the jamming of the push pin plate 50 caused by shaking or tilting during movement, that is, ensuring the smoothness of the movement of the push pin plate 50.

[0087] like Figures 1 to 17 As shown, in some embodiments of the present application, the movable seat 20 further includes: a body 26 and a fixing frame 27 .

[0088] The body 26 is disposed on the main body 10 .

[0089] The fixing frame 27 is disposed on the body 26 and encloses an installation space 21 with the body 26 . The fixing frame 27 is located between the body 26 and the extrusion seat 11 .

[0090] When all the staples 40 are pushed out of the installation space 21, the fixing frame 27 can be removed from the body 26, and then the fixing frame 27 with the staples 40 can be installed on the body 26. On the one hand, the cumbersome process of loading multiple staples 40 into the fixing frame 27 one by one is avoided, that is, the steps of replacing the staples 40 are reduced, and the replacement efficiency of the staples 40 is improved; on the other hand, when the fixing frame 27 or the staples 40 are damaged, the parts of the fixing frame 27 or the staples 40 can be quickly disassembled and replaced, reducing the maintenance time and cost.

[0091] like Figures 1 to 18 As shown, the driving assembly 30 includes a transmission member 31 and a driving device 32 .

[0092] The transmission member 31 is disposed on the main body 10 and connected to the moving seat 20 . The transmission member 31 can slide along a straight line relative to the main body 10 . The transmission member 31 is configured to drive the moving seat 20 to move relative to the main body 10 .

[0093] The driving device 32 is disposed on the main body 10 and connected to the transmission member 31 . The driving device 32 is configured to drive the transmission member 31 to move relative to the main body 10 .

[0094] like Figures 1 to 17 As shown, the transmission member 31 is a transmission plate, and the driving device 32 is a sector gear and a control cable; Fig.18 As shown, the transmission member 31 is a transmission rod, and the driving device 32 is a control cable.

[0095] Those skilled in the art should understand that any drive component 30 in the prior art can be applied to the present application as long as the drive requirements are met. In addition, the above-mentioned drive component 30 and the drive component 30 shown in the accompanying drawings are only a few specific embodiments and cannot limit the structure of the drive component 30.

[0096] Several embodiments of the driving member are described in detail below with reference to the accompanying drawings.

[0097] Embodiment 1

[0098] like Figures 1 to 6 As shown, the driving member 60 is a connecting rod 61 , the connecting rod 61 is rotatably connected to the movable seat 20 , and the push pin plate 50 and the connecting rod 61 can move relative to each other.

[0099] After the movable seat 20 and the extrusion seat 11 fix the mucosal tissue, operate the control member 70, the control member 70 drives the connecting rod 61 to rotate relative to the movable seat 20, the connecting rod 61 moves relative to the push needle plate 50, and drives the push needle plate 50 to move, the push needle plate 50 pushes the staples 40 out of the installation space 21, so that the staples 40 suture the human body.

[0100] The connecting rod 61 has a simple structure and is easy to manufacture and maintain. In addition, the connecting rod 61 can accurately transmit force and movement, ensuring the stability and reliability of the movement, thereby ensuring that the push pin plate 50 has a large thrust, thereby making it easier for the stapler 40 to penetrate the diseased mucosal tissue, so as to be able to effectively suture the mucosal tissue.

[0101] like Figure 6 As shown, in some embodiments of the present application, a slide groove 611 is provided on the connecting rod 61 , a sliding member 51 is provided on the push pin plate 50 , and the sliding member 51 is disposed in the slide groove 611 and can slide in the slide groove 611 .

[0102] The above connection structure is simple and easy to manufacture and maintain.

[0103] like Figure 6 As shown, in some embodiments of the present application, the connecting rod 61 includes a first portion 612 and a second portion 613 connected in sequence, and the first portion 612 is tilted relative to the second portion 613 .

[0104] The above structure reduces the space occupied by the connecting rod 61 in the length direction, thereby reducing the space occupied by the staple releasing device in the width direction, so that the staple releasing device can be smoothly inserted into or withdrawn from the human body.

[0105] like Figures 1 to 6 As shown, in some embodiments of the present application, an elastic reset member 62 is provided between the connecting rod 61 and the movable seat 20 , and the elastic reset member 62 is connected to the connecting rod 61 and the movable seat 20 , respectively.

[0106] When the connecting rod 61 rotates in the positive direction relative to the moving seat 20, the elastic reset member 62 stores force. When the connecting rod 61 is controlled to rotate in the reverse direction relative to the moving seat 20, the elastic reset member 62 releases the stored force, thereby helping the connecting rod 61 to return to the initial position, which ensures the reliability of the operation.

[0107] Embodiment 2

[0108] like Figures 8 to 12 As shown, the push pin plate 50 is provided with a first meshing tooth 52 .

[0109] The driving member 60 includes a rotating member 63 and a rotating rod 64 .

[0110] The rotating member 63 is provided with second meshing teeth, and the second meshing teeth mesh with the first meshing teeth 52 .

[0111] One end of the rotating rod 64 is fixedly connected to the rotating member 63 , and the other end of the rotating rod 64 is connected to the control member 70 .

[0112] The rotating member 63 is a sector gear 631 .

[0113] After the moving seat 20 and the extrusion seat 11 fix the mucosal tissue, operate the control member 70, and the control member 70 drives the fan gear 631 to rotate relative to the moving seat 20 through the rotating rod 64. The second meshing teeth on the fan gear 631 interact with the first meshing teeth 52 on the push pin plate 50, so that the fan gear 631 drives the push pin plate 50 to move, so that the push pin plate 50 pushes the staples 40 out of the installation space 21, so that the staples 40 suture the human body.

[0114] The above structure is a gear transmission system, which has the advantages of accurate transmission, high efficiency, compact structure, reliable operation and long service life.

[0115] The sector gear 631 has high space utilization and is relatively small in shape, so that the transmission function can be realized in a limited space, thereby improving the space utilization of the stapler release device and the transmission power and stability of the gear transmission.

[0116] like Figures 8 to 12 As shown, in some embodiments of the present application, an elastic reset member 62 is provided between the rotating member 63 and the moving seat 20 , and the elastic reset member 62 is connected to the rotating member 63 and the moving seat 20 respectively.

[0117] When the rotating member 63 rotates in the positive direction relative to the moving seat 20, the elastic reset member 62 stores force. When the rotating member 63 is controlled to rotate in the reverse direction relative to the moving seat 20, the elastic reset member 62 releases the stored force, thereby helping the rotating member 63 to return to the initial position, which ensures the reliability of the operation.

[0118] Embodiment 3

[0119] like Figures 13 to 17 As shown, the structure of the third embodiment is substantially the same as that of the second embodiment, with the specific difference being that the rotating member 63 includes a transmission gear 632 and a driving gear 633 .

[0120] The transmission gear 632 meshes with the first meshing teeth 52 .

[0121] The driving gear 633 is connected to the rotating rod 64 and meshes with the transmission gear 632 .

[0122] After the movable seat 20 and the extrusion seat 11 fix the mucosal tissue, the control member 70 is operated. The control member 70 drives the driving gear 633 to rotate relative to the movable seat 20 through the rotating rod 64. The driving gear 633 drives the transmission gear 632 to rotate relative to the movable seat 20. The transmission gear 632 drives the push pin plate 50 to move, so that the push pin plate 50 pushes the stapler 40 out of the installation space 21, so that the stapler 40 sutures the human body.

[0123] The above structure is a multi-stage gear transmission system, which can improve the transmission efficiency of the transmission device and ensure the effective transmission of the driving force.

[0124] In some embodiments of the present application, the diameter of the driving gear 633 is smaller than the diameter of the transmission gear 632. The small-sized driving gear 633 drives the large-sized transmission gear 632. On the one hand, the transmission gear 632 can output a larger torque, so that the needle plate 50 can obtain a greater force, so that the staples 40 can more easily penetrate the diseased mucosal tissue, so as to effectively suture the mucosal tissue.

[0125] like Figures 1 to 17As shown, the suturing device provided by the embodiment of the second aspect of the present application includes: the above-mentioned staple releasing device and staples.

[0126] The staples are arranged in the installation space of the staple releasing device, and the staples can be squeezed and deformed.

[0127] The suturing device provided in the present application is independently provided with a driving member for the staples, which provides the staples with sufficient puncture force to ensure their reliability; in addition, the suturing device sutures the human mucosal tissue only through simple pushing and pulling actions, without other complicated operating methods, which reduces the operating difficulty of the product.

[0128] like Figures 1 to 17 As shown, in some embodiments of the present application, the extension direction of the guide slot 25 of the staple releasing device is the same as the moving direction of the staples, so that the push pin plate 50 and the staples are coplanar.

[0129] Before inserting the suturing device into the human body, the push needle plate 50 is overlapped with the stapler 40, so as to avoid the large space occupied by the driving member resulting in the excessive volume of the suturing device. Even if the overall volume of the product is small, the stapler release device can be smoothly inserted into or withdrawn from the human body, thereby improving the comfort of the product and reducing the risk of scratching the mucosal tissue during the process of the device entering and withdrawing from the human body cavity.

[0130] like Figures 1 to 17 As shown, in some embodiments of the present application, there are multiple staples 40, and multiple staples 40 are stacked to form a staple group.

[0131] The suturing device further includes a needle box 81 and an elastic member 82 .

[0132] The needle box 81 is arranged in the installation space 21, and the needle box 81 has an open accommodating cavity at one end. The staple group is arranged in the accommodating cavity. The staple 40 farthest from the bottom wall of the accommodating cavity among the multiple staples 40 corresponds to the needle push plate 50. The bottom wall of the accommodating cavity refers to: the cavity wall arranged opposite to the opening of the accommodating cavity.

[0133] The elastic member 82 is supported between the staple group and the bottom wall.

[0134] The above structure can realize continuous suturing of mucosal tissue, reduce the number of times of installing the staples 40, and thus improve the use efficiency of the product.

[0135] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application.
