Endoscopic stapling and suturing device

Abstract

The application discloses an endoscopic anastomosis nail releasing device and an endoscopic suturing device, wherein the endoscopic anastomosis nail releasing device comprises a main body, a rotating seat, a driving device, a needle pushing plate, a transmission device and a control member. In use, the mucosa tissue is first fixed by extrusion through the action of the extrusion seat and the rotating seat, and then the mucosa tissue is punctured and sutured by the anastomosis nail. The above suture process includes two operations. On the one hand, during the process of fixing the mucosa tissue, the extrusion seat and the rotating seat can be adjusted multiple times until the mucosa tissue is accurately and effectively fixed, thereby ensuring the accuracy of the subsequent anastomosis nail puncturing the mucosa tissue. On the other hand, the extrusion seat and the rotating seat jointly extrude the blood vessels in the mucosa tissue, have a certain hemostatic effect on the blood vessels, reduce the probability of bleeding in the process of the subsequent anastomosis nail puncturing the mucosa tissue, and can effectively improve the safety of the product.

Description

Technical Field

[0001] This application relates to the field of medical device technology for endoscopic minimally invasive surgery, and in particular to an endoscopic anastomosis staple release device and an endoscopic suturing device. Background Technology

[0002] With the development of endoscopic technology and instruments, an increasing number of diseases can be treated using minimally invasive endoscopic techniques. Addressing conditions such as gastroesophageal reflux disease, obesity, hyperglycemia, and hyperlipidemia through minimally invasive endoscopic techniques is both a significant challenge and a hot topic. This allows patients to avoid the trauma of surgical procedures.

[0003] Currently, the emergence of some flexible endoscopic suturing instruments has brought hope for minimally invasive treatment of these types of diseases, such as fundoplication for gastroesophageal reflux disease and gastric reduction surgery for obese patients.

[0043] Compared with existing technologies, the above technical solution has the following advantages:

[0044] After the stapler enters the human body, it pulls the mucosal tissue into the stapler. Then, the drive device drives the rotating seat to rotate relative to the main body, changing the distance between the rotating seat and the compression seat. During this process, the rotating seat and the compression seat jointly compress the mucosal tissue. Then, the control component controls the movement of the transmission device relative to the rotating seat. The transmission device drives the pusher plate to move relative to the rotating seat, so that the pusher plate pushes the anastomosis staple out of the installation space and penetrates the mucosal tissue. After the anastomosis staple is deformed by the compression seat, it sutures the mucosal tissue. In the above-mentioned mucosal tissue suturing process, the mucosal tissue is first fixed by the action of the compression seat and the rotating seat, and then the mucosal tissue is sutured by the anastomosis staple. On the one hand, it can effectively improve the accuracy and safety of subsequent punctures, ensuring that the anastomosis staple effectively sutures the mucosal tissue, thereby ensuring safe and effective treatment of the mucosal tissue. On the other hand, the above operation requires simple pushing and pulling actions, without complicated other operation methods, reducing the difficulty of product operation and thus effectively improving the comfort of product use.

[0045] An embodiment of the second aspect of this application provides an endoscopic suturing device, including the endoscopic anastomosis staple release device described in any of the preceding claims; and an anastomosis staple disposed within the installation space of the endoscopic anastomosis staple release device, the anastomosis staple being compressible and deformable.

[0046] In some embodiments, the extension direction of the guide groove of the endoscopic staple release device is the same as the movement direction of the staple, so that the staple and the pusher plate are coplanar.

[0047] In some embodiments, the number of anastomotic staples is multiple, and the stacked arrangement of multiple anastomotic staples constitutes an anastomotic staple group; the endoscopic anastomotic staple release device and the endoscopic suturing device further include: a needle box disposed in the installation space, the needle box having an open receiving cavity at one end, the anastomotic staple group disposed in the receiving cavity, the anastomotic staple farthest from the bottom wall of the receiving cavity among the multiple anastomotic staples corresponding to the pusher plate, the bottom wall of the receiving cavity referring to: the cavity wall of the receiving cavity disposed opposite to the opening; and a second elastic member supported between the anastomotic staple group and the bottom wall.

[0048] Compared with existing technologies, the above technical solution has the following advantages:

[0049] Endoscopic suturing devices can effectively improve the accuracy and safety of subsequent punctures, ensuring that the staples effectively suture the mucosal tissue, thereby guaranteeing safe and effective treatment of the mucosal tissue. In addition, endoscopic suturing devices only require simple pushing and pulling movements to suture human mucosal tissue, without complicated other operating methods, reducing the difficulty of product operation and thus effectively improving the comfort of product use.

[0166] like Figures 1a to 91 As shown, the endoscopic anastomosis staple release device provided in the first aspect of this application includes: a main body 10, a rotating seat 20, a driving device 30, a pusher plate 50, a transmission device 60, and a control component 70.

[0167] The main body 10 is provided with a compression seat 11 and a through hole 12 passing through it, the through hole 12 being configured to cooperate with the endoscope 100.

[0168] The rotating seat 20 is mounted on the main body 10 and is rotatable relative to the main body 10. The rotating seat 20 is provided with an installation space 21, which is configured to accommodate the staples 40.

[0169] The drive device 30 is mounted on the main body 10 and connected to the rotating seat 20. The drive device 30 is configured to drive the rotating seat 20 to rotate relative to the main body 10.

[0170] The pusher plate 50 is disposed on the rotating seat 20 and is movable relative to the rotating seat 20 to be inserted into the installation space 21. The pusher plate 50 is configured to push the staple 40 out of the installation space 21.

[0171] The transmission device 60 is mounted on the rotating seat 20 and is movable relative to the rotating seat 20. The transmission device 60 is connected to the pusher plate 50 and is configured to drive the pusher plate 50 to move relative to the rotating seat 20.

[0172] The control element 70 is connected to the transmission device 60 and is configured to drive the transmission device 60 to move relative to the rotating seat 20.

[0173] The endoscopic anastomosis staple release device provided in this application, during use, first fixes the mucosal tissue through the action of the compression seat 11 and the rotating seat 20, and then sutures the mucosal tissue with the anastomosis staple 40. The suturing process includes two operations. On the one hand, during the fixation of the mucosal tissue, multiple adjustments can be made until the compression seat 11 and the rotating seat 20 can accurately and effectively fix the mucosal tissue, thereby ensuring the accuracy of the subsequent puncture of the mucosal tissue by the anastomosis staple 40. On the other hand, the compression seat 11 and the rotating seat 20 jointly compress the blood vessels inside the mucosal tissue, which has a certain hemostatic effect on the blood vessels, reducing the probability of bleeding during the subsequent puncture of the mucosal tissue by the anastomosis staple 40, and effectively improving the safety of the product. Therefore, the endoscopic anastomosis staple release device can effectively suture the mucosal tissue, thereby ensuring safe and effective treatment of the mucosal tissue.

[0174] In addition, the operator of the endoscopic staple release device only needs simple pushing and pulling movements, without any complicated other operating methods, which reduces the difficulty of operating the product and thus effectively improves the user's comfort.

[0175] The specific operation of the endoscopic staple release device is as follows:

[0176] The first step is to install the anastomosis staple 40 in the fitting space 21, and then to attach the endoscopic anastomosis staple release device to the front end of the endoscope 100. Finally, the endoscopic anastomosis staple release device is inserted into the surgical site inside the body along with the endoscope 100.

[0177] The second step involves using the drive device 30 to rotate the rotating seat 20 away from the compression seat 11, increasing the distance between them. Then, the endoscopic tissue to be punctured is clamped or anchored using endoscopic instruments such as endoscopic forceps and pulled into the space between the rotating seat 20 and the compression seat 11. Afterward, the drive device 30 rotates the rotating seat 20 closer to the compression seat 11, so that the rotating seat 20 and the compression part 23 can compress and fix the mucosal tissue. If the endoscope 100 observes that the clamping position of the rotating seat 20 and the compression part 23 on the mucosal tissue is incorrect, the above operation can be repeated multiple times to ensure that the compression seat 11 and the rotating seat 20 can accurately and effectively fix the mucosal tissue.

[0178] The third step involves controlling the transmission device 60 to move relative to the rotating seat 20 via the control component 70. The transmission device 60 drives the pusher plate 50 to move relative to the rotating seat 20, so that the pusher plate 50 pushes the anastomosis staple 40 out of the installation space 21 and penetrates the mucosal tissue. After the anastomosis staple 40 is deformed by the compression seat 11, it sutures the mucosal tissue.

[0179] The fourth step involves controlling the transmission device 60 to move in the opposite direction to the rotating seat 20 via the control component 70. The transmission device 60 drives the pusher plate 50 to retract from the installation space 21 to make room for the installation of the anastomosis staple 40, thus preparing for the second puncture and suturing.

[0180] like Figure 6a As shown, in some embodiments of this application, the rotating seat 20 includes a rotating arm 22 and a pressing part 23.

[0181] The rotating arm 22 is mounted on the main body 10 and can rotate relative to the main body 10. One end of the rotating arm 22 is connected to the drive device 30.

[0182] The extrusion section 23 is connected to the other end of the rotating arm 22, and the extrusion section 23 is provided with an installation space 21.

[0183] The squeezing part 23 cooperates with the squeezing seat 11 to fix the mucosal tissue. The rotating arm 22 occupies a small volume, which reduces the space occupied by the rotating seat 20 and makes the overall size of the product smaller. This allows the endoscopic anastomosis staple release device to be smoothly inserted into or withdrawn from the human body, improving the comfort of the product. At the same time, it reduces the probability of scratching the mucosal tissue during the process of the device entering and withdrawing from the human lumen.

[0184] like Figure 4 As shown, in some embodiments of this application, a clearance space 24 is provided at one end of the extrusion part 23 that is connected to the rotating arm 22, and the clearance space 24 is positioned corresponding to the position of the through hole 12.

[0185] Because the endoscope 100 is installed inside the through hole 12, the clearance space 24 prevents the squeezing part 23 from obstructing the visual range of the endoscope 100, allowing the operator to see the condition of the mucosal tissue more clearly, avoiding blind spots and potential dangers, thereby enabling more accurate and effective suturing of the mucosal tissue.

[0186] like Figure 4 and Figure 8 As shown, in some embodiments of this application, the main body 10 is provided with a clearance space 13, and one end of the rotating arm 22 connected to the driving device 30 is located in the clearance space 13.

[0187] The provision of the clearance space 13 allows part of the rotating arm 22 to overlap with the space occupied by the main body 10, reducing the space occupied by the rotating arm 22 and making the overall size of the product smaller. This allows the endoscopic staple release device to be smoothly inserted into or withdrawn from the human body, improving the comfort of the product. At the same time, it reduces the probability of scratching the mucosal tissue during the process of the device entering and withdrawing from the human body lumen.

[0188] In some embodiments of this application, there are two rotating arms 22, and the drive device 30 is connected to the two rotating arms 22. Specifically, the two rotating arms 22 are symmetrically arranged on the extrusion section 23.

[0189] The arrangement of two rotating arms 22 ensures that the extrusion part 23 is subjected to uniform force and provides sufficient rotational power, which helps the rotating seat 20 to rotate more smoothly, thereby reducing the jamming of the rotating seat 20 caused by shaking or tilting during rotation. This ensures the smoothness of the rotation of the rotating seat 20 and the comfort of using the product.

[0190] like Figures 1a to 5 As shown, in some embodiments of this application, the rotating seat 20 is provided with a mating space 25, and the transmission device 60 is disposed within the mating space 25.

[0191] The arrangement of space 25 allows the space occupied by transmission device 60 and rotating seat 20 to overlap, reducing the space occupied by transmission device 60 and making the overall size of the product smaller. This allows the endoscopic staple release device to be smoothly inserted into or withdrawn from the human body, improving the comfort of the product. At the same time, it reduces the probability of scratching the mucosal tissue during the process of the device entering and withdrawing from the human body lumen.

[0192] like Figures 1a to 5 As shown, in some embodiments of this application, a second elastic reset member 82 is provided between the rotating base 20 and the main body 10, and the second elastic reset member 82 is connected to both the rotating base 20 and the main body 10. Specifically, the second elastic reset member 82 is a torsion spring.

[0193] When the rotating seat 20 rotates in the positive direction relative to the main body 10, the second elastic reset member 82 stores force. When the rotating seat 20 is controlled to rotate in the opposite direction relative to the main body 10, the second elastic reset member 82 releases the stored force, which helps the rotating seat 20 return to the initial position, thereby reducing the difficulty of operation.

[0194] like Figures 1a to 6c As shown, in some embodiments of this application, the rotary seat 20 is provided with a first clearance hole 29 that passes through it. The first clearance hole 29 communicates with the mounting space 21, and the position of the first clearance hole 29 corresponds to the position of the through hole 12.

[0195] When the product is inserted into the human body, the endoscope can see the condition of the mucosal tissue at the front end of the product through the first avoidance hole 29, avoiding blind spots and potential dangers, so that the product can reach the position that needs to be sutured more accurately.

[0196] like Figure 6c As shown, in some embodiments of this application, one sidewall of the mounting space 21 is a cover plate 201, which is detachably connected to the rotating seat 20.

[0197] When it is necessary to install the staples 40 into the installation space 21, the cover plate 201 is removed, the staples 40 are then installed into the installation space 21, and the cover plate 201 is then fixedly connected to the rotating seat 20. This structure facilitates the installation of the staples 40. During the installation process, the staples 40 can be installed one by one into the installation space 21 in multiple stages, or multiple staples 40 can be assembled into a single component and installed together into the installation space 21.

[0198] In addition, the installation space can be set inside the rotating base, or it can be formed by other structures fixed on the rotating base together with the rotating base.

[0199] like Figures 1a to 6b As shown, in some embodiments of this application, the rotating seat 20 is provided with a guide groove 26, the pusher plate 50 is inserted into the guide groove 26, and can move within the guide groove 26.

[0200] The guide groove 26 guides the movement trajectory of the pusher plate 50, which helps the pusher plate 50 move more smoothly, thereby reducing the sticking of the pusher plate 50 due to shaking or tilting during movement, thus ensuring the smoothness of the pusher plate 50 movement.

[0201] like Figures 44 to 58 As shown, in some embodiments of this application, the compression seat 11 includes a connecting plate 111 and a compression plate 112.

[0202] The connecting plate 111 is connected to the main body 10.

[0203] The extrusion plate 112 is connected to the connecting plate 111 and is inclined relative to the connecting plate 111. In some embodiments of this application, the included angle between the extrusion plate 112 and the connecting plate 111 is a non-acute angle.

[0204] The needle outlet 211 of the mounting space 21 is located on the top surface of the rotating seat 20, with the top surface facing the surface of the extrusion plate 112, and the axis of the needle outlet 211 is perpendicular to the surface of the extrusion plate 112.

[0205] The top surface of the rotating seat 20 refers to the surface on the end of the rotating seat 20 away from the end that is connected to the main body 10.

[0206] The shape of the aforementioned compression seat 11 makes the needle exit direction of the anastomosis staple 40 the length direction of the product, thereby reducing the width of the product in the width direction. This makes the endoscopic anastomosis staple release device as a whole "slender" shape, which in turn allows the endoscopic anastomosis staple release device to be smoothly inserted into or withdrawn from the human body, improving the comfort of using the product. At the same time, it reduces the probability of scratching the mucosal tissue during the process of the device entering and withdrawing from the human body lumen.

[0207] In addition, the above structure makes the direction of the force input by the control element 70 to the transmission device 60 the same as the direction of the force output by the transmission device 60 to the pusher plate 50. This allows the force output by the control element 70 to be effectively applied to the pusher plate 50, giving the pusher plate 50 a larger thrust. This makes it easier for the staples 40 to penetrate the mucosal tissue, enabling effective suturing of the mucosal tissue.

[0208] like Figures 44 to 58 As shown, in some embodiments of this application, the extrusion plate 112 is provided with a second clearance hole 113, and the position of the second clearance hole 113 corresponds to the position of the through hole 12.

[0209] When the product is inserted into the human body, the endoscope 100 can see the condition of the mucosal tissue at the front end of the product through the second clearance hole 113, avoiding blind spots and potential dangers, so that the product can reach the position that needs to be sutured more accurately.

[0210] The following describes several embodiments of the transmission device in detail with reference to the accompanying drawings.

[0211] Example 1

[0212] like Figures 1a to 5 As shown, the transmission device 60 is a connecting rod 61, which is rotatably connected to the rotating seat 20. One end of the connecting rod 61 is connected to the control component 70, and the other end of the connecting rod 61 is connected to the push needle plate 50. The push needle plate 50 and the connecting rod 61 can move relative to each other.

[0213] After the rotating seat 20 and the squeezing seat 11 fix the mucosal tissue, the operating control component 70 is activated. The control component 70 drives the connecting rod 61 to rotate relative to the rotating seat 20. The connecting rod 61 moves relative to the pusher plate 50 and drives the pusher plate 50 to move. The pusher plate 50 pushes the anastomosis staple 40 out of the installation space 21 so that the anastomosis staple 40 can suture the human body.

[0214] The connecting rod 61 has a simple structure, 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 pusher plate 50 has a large thrust, which makes it easier for the staple 40 to penetrate the mucosal tissue, so as to effectively suture the mucosal tissue.

[0215] like Figure 7 As shown, in some embodiments of this application, the connecting rod 61 is provided with a groove 611, and the pusher plate 50 is provided with a slider 51. The slider 51 is disposed in the groove 611 and can slide in the groove 611.

[0216] The above connection structure is simple and easy to manufacture and maintain.

[0217] like Figure 7As shown, in some embodiments of this application, the connecting rod 61 includes a first part 612 and a second part 613 connected in sequence, with the first part 612 being inclined relative to the second part 613.

[0218] The above structure reduces the space occupied by the connecting rod 61 in the length direction, thereby reducing the space occupied by the endoscopic staple release device in the width direction. This allows the endoscopic staple release device to be smoothly inserted into or withdrawn from the human body, improving the comfort of the product. At the same time, it reduces the probability of scratching the mucosal tissue during the device's entry into and withdrawal from the human body lumen.

[0219] like Figures 1a to 5 As shown, in some embodiments of this application, a first elastic reset member 81 is provided between the connecting rod 61 and the rotating seat 20, and the first elastic reset member 81 is connected to the connecting rod 61 and the rotating seat 20 respectively.

[0220] When the connecting rod 61 rotates in the positive direction relative to the rotating seat 20, the first elastic reset member 81 stores force. When the connecting rod 61 rotates in the opposite direction relative to the rotating seat 20, the first elastic reset member 81 releases the stored force, which helps the connecting rod 61 return to its initial position, thus ensuring the reliability of operation.

[0221] like Figures 44 to 52 As shown, in some embodiments of this application, the compression seat 11 includes a connecting plate 111 and a compression plate 112.

[0222] The connecting plate 111 is connected to the main body 10.

[0223] The extrusion plate 112 is connected to the connecting plate 111 and is inclined relative to the connecting plate 111. In some embodiments of this application, the included angle between the extrusion plate 112 and the connecting plate 111 is a non-acute angle.

[0224] The needle outlet 211 of the mounting space 21 is located on the top surface of the rotating seat 20, with the top surface facing the surface of the extrusion plate 112, and the axis of the needle outlet 211 is perpendicular to the surface of the extrusion plate 112.

[0225] The top surface of the rotating seat 20 refers to the surface on the end of the rotating seat 20 away from the end that is connected to the main body 10.

[0226] The shape of the aforementioned compression seat 11 makes the direction of the staple exit point along the length of the product, thereby reducing the width of the product in the width direction. This makes the endoscopic staple release device as a whole "slender" shape, which allows the endoscopic staple release device to be smoothly inserted into or withdrawn from the human body, improving the comfort of using the product. At the same time, it reduces the probability of scratching the mucosal tissue during the process of the device entering and withdrawing from the human lumen.

[0227] In addition, the above structure makes the direction of the force input by the control element 70 to the transmission device 60 the same as the direction of the force output by the transmission device 60 to the pusher plate 50. This allows the force output by the control element 70 to be effectively applied to the pusher plate 50, giving the pusher plate 50 a larger thrust. This makes it easier for the staples 40 to penetrate the mucosal tissue, enabling effective suturing of the mucosal tissue.

[0228] like Figures 44 to 52 As shown, in some embodiments of this application, the extrusion plate 112 is provided with a second clearance hole 113, and the position of the second clearance hole 113 corresponds to the position of the through hole 12.

[0229] When the product is inserted into the human body, the endoscope 100 can see the condition of the mucosal tissue at the front end of the product through the second clearance hole 113, avoiding blind spots and potential dangers, so that the product can reach the position that needs to be sutured more accurately.

[0230] Example 2

[0231] like Figures 9 to 13 As shown, the transmission device 60 includes a movable component 62 and a transmission component 63.

[0232] The movable element 62 is disposed on the rotating base 20 and can slide along a straight line relative to the rotating base 20. The movable element 62 is connected to the control element 70.

[0233] The transmission component 63 is connected to the moving component 62 and the pusher plate 50 respectively. The transmission component 63 is configured to drive the pusher plate 50 to move relative to the rotating seat 20.

[0234] The transmission component 63 is a transmission plate 631. One end of the transmission plate 631 is rotatably connected to the moving component 62, and the other end of the transmission plate 631 is connected to the pusher plate 50. The pusher plate 50 and the transmission plate 631 can move relative to each other.

[0235] The movable component 62 is a movable block 621, which includes a guide portion 622 and a connecting portion 623.

[0236] The guide part 622 is connected to the rotating seat 20 and can slide on the rotating seat 20.

[0237] The connecting part 623 is connected to the transmission member 63, and the transmission member 63 can rotate relative to the connecting part 623.

[0238] After the rotating seat 20 and the squeezing seat 11 fix the mucosal tissue, the operating control unit 70 is activated. The control unit 70 drives the moving block 621 to move relative to the rotating seat 20. The moving block 621 drives the transmission plate 631 to move relative to the rotating seat 20. The transmission plate 631 drives the pusher plate 50 to move, so that the pusher plate 50 pushes the anastomosis staple 40 out of the installation space 21, so that the anastomosis staple 40 can suture the human body.

[0239] The moving block 621 and the transmission plate 631 are a multi-stage transmission mechanism. On the one hand, they can distribute the load and reduce the force on the moving block 621 and the transmission plate 631, thereby improving the reliability and durability of the transmission device 60. On the other hand, the transmission device 60 has better degrees of freedom and movement possibilities, thereby improving the smoothness and stability of the transmission and making the operation of the product smoother.

[0240] In addition, the high mechanical strength of the moving block 621 and the transmission plate 631 reduces the probability of damage to the transmission device 60, improves the reliability of the product, and thus increases the product's market competitiveness.

[0241] like Figure 14 As shown, in one embodiment of this application, the connecting portion 623 is provided with a receiving space 624, and the transmission member 63 is disposed within the receiving space 624.

[0242] The arrangement of the accommodating space 624 allows the space occupied by the transmission component 63 and the connecting part 623 to overlap, reducing the space occupied by the transmission device 60 and making the overall size of the product smaller. This allows the endoscopic staple release device to be smoothly inserted into or withdrawn from the human body, improving the comfort of using the product. At the same time, it reduces the probability of scratching the mucosal tissue during the process of the device entering and withdrawing from the human body lumen.

[0243] like Figures 9 to 13 As shown, in some embodiments of this application, the transmission device 60 further includes a first elastic member 64.

[0244] The first elastic element 64 is supported between the movable element 62 and the rotating seat 20.

[0245] When the movable member 62 moves in the positive direction relative to the rotating seat 20, the first elastic member 64 stores force. When the movable member 62 is controlled to rotate in the opposite direction relative to the rotating seat 20, the first elastic member 64 releases the stored force, thereby helping the movable member 62 return to the initial position.

[0246] Example 3

[0247] like Figures 15 to 21 As shown, the structure of Embodiment 3 is largely the same as that of Embodiment 2, with the specific difference being that: the transmission component 63 is a guide block 632, which is fixed on the moving component 62. The guide block 632 is provided with a first guide slope 633, and the first guide slope 633 is provided with a first guide structure 634. Specifically, the guide block 632 and the moving component 62 are an integral structure.

[0248] The pusher plate 50 is provided with a second guide slope 52 that is adapted to the first guide slope 633. The second guide slope 52 is provided with a second guide structure 53 that is adapted to the first guide structure 634. The first guide structure 634 and the second guide structure 53 are connected and can slide relative to each other.

[0249] After the rotating seat 20 and the compression seat 11 fix the mucosal tissue, the operating control unit 70 is activated. The control unit 70 drives the moving block 621 to move relative to the rotating seat 20. The moving block 621 drives the guide block 632 to move relative to the rotating seat 20. Through the cooperation of the first guide inclined surface 633 and the second guide inclined surface 52 and the cooperation of the first guide structure 634 and the second guide structure 53, the guide block 632 drives the pusher plate 50 to move, so that the pusher plate 50 pushes the anastomosis staple 40 out of the installation space 21, so that the anastomosis staple 40 can suture the human body.

[0250] The moving block 621 and guide block 632 are multi-stage transmission mechanisms. On the one hand, they can distribute the load and reduce the force on the moving block 621 and guide block 632, thereby improving the reliability and durability of the transmission device 60. On the other hand, the transmission device 60 has better degrees of freedom and movement possibilities, thereby improving the smoothness and stability of the transmission and making the operation of the product smoother.

[0251] In addition, the moving block 621 and the guide block 632 have a large thickness, which means that the moving block 621 and the guide block 632 have high mechanical strength, thus improving the reliability of the product.

[0252] Example 4

[0253] like Figures 22 to 26 As shown, the structure of Embodiment 4 is largely the same as that of Embodiment 2, except that the movable part 62 is a slide rod 625, which can slide on the rotating seat 20.

[0254] The slide rod 625 is connected to the transmission component 63, and the transmission component 63 can rotate relative to the slide rod 625.

[0255] After the rotating seat 20 and the compression seat 11 fix the mucosal tissue, the operating control component 70 is activated. The control component 70 drives the slide rod 625 to move relative to the rotating seat 20. The slide rod 625 drives the transmission component 63 to move relative to the rotating seat 20. The transmission component 63 drives the pusher plate 50 to move, so that the pusher plate 50 pushes the anastomosis staple 40 out of the installation space 21, so that the anastomosis staple 40 can suture the human body.

[0256] The slide bar 625 has a simple structure, is easy to manufacture and maintain. In addition, the slide bar 625 is small in size, which reduces the space occupied by the slide bar 625 in the rotating seat 20, thereby reducing the space occupied by the rotating seat 20 and making the overall size of the product smaller. This allows the endoscopic staple release device to be smoothly inserted into or withdrawn from the human body, improving the flexibility and safety of the product.

[0257] Example 5

[0258] like Figures 27 to 31 As shown, the pusher plate 50 is provided with a first meshing tooth 54.

[0259] The transmission device 60 includes a rotating component 65 and a rotating rod 66.

[0260] The rotating member 65 is provided with a second meshing tooth, which meshes with the first meshing tooth 54. In one embodiment of this application, a third elastic reset member is provided between the rotating member and the rotating seat, which helps the third elastic reset member return to its initial position, thereby reducing the difficulty of operation.

[0261] One end of the rotating rod 66 is fixedly connected to the rotating component 65, and the other end of the rotating rod 66 is connected to the control component 70.

[0262] The rotating component 65 is a sector gear 651.

[0263] After the rotating seat 20 and the compression seat 11 fix the mucosal tissue, the operating control unit 70 is activated. The control unit 70 drives the sector gear 651 to rotate relative to the rotating seat 20 through the rotating rod 66. The second meshing tooth on the sector gear 651 interacts with the first meshing tooth 54 on the pusher plate 50. The sector gear 651 drives the pusher plate 50 to move, so that the pusher plate 50 pushes the anastomosis staple 40 out of the installation space 21, so that the anastomosis staple 40 can suture the human body.

[0264] The above structure is a gear transmission system. Gear transmission systems have relatively accurate transmission, high efficiency, compact structure, reliable operation, and long service life.

[0265] The sector gear 651 has high space utilization. The sector gear 651 has a relatively small shape and can realize the transmission function in a limited space, thereby improving the space utilization of the endoscopic anastomosis staple release device.

[0266] like Figures 53 to 58 As shown, in some embodiments of this application, the compression seat 11 includes a connecting plate 111 and a compression plate 112.

[0267] The connecting plate 111 is connected to the main body 10.

[0268] The extrusion plate 112 is connected to the connecting plate 111 and is inclined relative to the connecting plate 111. In some embodiments of this application, the included angle between the extrusion plate 112 and the connecting plate 111 is a non-acute angle.

[0269] The needle outlet 211 of the mounting space 21 is located on the top surface of the rotating seat 20, with the top surface facing the surface of the extrusion plate 112, and the axis of the needle outlet 211 is perpendicular to the surface of the extrusion plate 112.

[0270] The top surface of the rotating seat 20 refers to the surface on the end of the rotating seat 20 away from the end that is connected to the main body 10.

[0271] The shape of the aforementioned compression seat 11 makes the direction of the staple exit point along the length of the product, thereby reducing the width of the product in the width direction. This makes the endoscopic staple release device as a whole "slender" shape, which allows the endoscopic staple release device to be smoothly inserted into or withdrawn from the human body, improving the comfort of using the product. At the same time, it reduces the probability of scratching the mucosal tissue during the process of the device entering and withdrawing from the human lumen.

[0272] In addition, the above structure makes the direction of the force input by the control element 70 to the transmission device 60 the same as the direction of the force output by the transmission device 60 to the pusher plate 50. This allows the force output by the control element 70 to be effectively applied to the pusher plate 50, giving the pusher plate 50 a larger thrust. This makes it easier for the staples 40 to penetrate the mucosal tissue, enabling effective suturing of the mucosal tissue.

[0273] like Figures 53 to 58 As shown, in some embodiments of this application, the extrusion plate 112 is provided with a second clearance hole 113, and the position of the second clearance hole 113 corresponds to the position of the through hole 12.

[0274] When the product is inserted into the human body, the endoscope 100 can see the condition of the mucosal tissue at the front end of the product through the second clearance hole 113, avoiding blind spots and potential dangers, so that the product can reach the position that needs to be sutured more accurately.

[0275] Example 6

[0276] like Figures 33 to 36 As shown, the structure of Embodiment Six is ​​largely the same as that of Embodiment Five, except that the rotating component 65 includes a transmission gear 652 and a drive gear 653.

[0277] The transmission gear 652 meshes with the first meshing tooth 54.

[0278] The drive gear 653 is connected to the rotating rod 66 and meshes with the transmission gear 652.

[0279] After the rotating seat 20 and the compression seat 11 fix the mucosal tissue, the operating control component 70 is activated. The control component 70 drives the drive gear 653 to rotate relative to the rotating seat 20 via the rotating rod 66. The drive gear 653 drives the transmission gear 652 to rotate relative to the rotating seat 20. The transmission gear 652 drives the pusher plate 50 to move, so that the pusher plate 50 pushes the anastomosis staple 40 out of the installation space 21, so that the anastomosis staple 40 can suture the human body.

[0280] The above structure is a multi-stage gear transmission system, which can improve the transmission efficiency of the transmission device 60 and ensure the effective transmission of driving force. In addition, a large transmission ratio can be achieved in a small space, and multi-stage gear transmission also has better stability and reliability.

[0281] In some embodiments of this application, the diameter of the drive gear 653 is smaller than the diameter of the transmission gear 652. The smaller drive gear 653 drives the larger transmission gear 652. On the one hand, this allows the transmission gear 652 to output a larger torque, thereby providing greater force to the pusher plate 50, making it easier for the staples 40 to penetrate the mucosal tissue for effective suturing. On the other hand, the smaller gear occupies less space, saving space and allowing for further reduction in product size.

[0282] Example 7

[0283] like Figures 37 to 43 As shown, the structure of Embodiment 7 is largely the same as that of Embodiment 4, with the transmission device 60 and the pusher plate 50 being the same component.

[0284] A first guide 55 is provided on one end of the pusher plate 50, and a second guide 56 is provided on the other end of the pusher plate 50. The control component 70 is connected to the other end of the pusher plate 50.

[0285] The rotating base 20 is provided with a first guide groove 27 that cooperates with the first guide member 55, and the rotating base 20 is provided with a second guide groove 28 that cooperates with the second guide member 56.

[0286] The extension direction of the first guide groove 27 intersects the extension direction of the second guide groove 28, and the extension direction of the first guide groove 27 is the same as the direction in which the staple 40 moves within the installation space 21.

[0287] After the rotating seat 20 and the squeezing seat 11 fix the mucosal tissue, the operating control unit 70 is activated. The control unit 70 drives the pusher plate 50 to rotate relative to the rotating seat 20. The pusher plate 50 pushes the anastomosis staple 40 out of the installation space 21 so that the anastomosis staple 40 can suture the human body.

[0288] The above structure is simple, with fewer components driving the movement of the pusher plate 50, resulting in a smaller overall product size. This allows the endoscopic staple release device to be smoothly inserted into or withdrawn from the human body, improving the product's flexibility and safety.

[0289] In some embodiments of this application, the first guide member 55 is further provided with a first rolling member, so that the friction between the first guide member 55 and the groove wall of the first guide groove 27 is rolling friction, thereby making the pusher plate 50 slide more smoothly relative to the rotating seat 20, improving the product's flexibility and stability. Similarly, the second guide member 56 is further provided with a second rolling member, so that the friction between the second guide member 56 and the groove wall of the second guide groove 28 is rolling friction, thereby making the pusher plate 50 slide more smoothly relative to the rotating seat 20, improving the product's comfort.

[0290] Example 8

[0291] like Figures 59 to 70 As shown, a guide space 202 is provided on the rotary base 20. Specifically, the guide space 202 can be a space opened on the rotary base 20, or it can be a separate component with the guide space 202 provided on the rotary base 20, the separate component being a guide tube 203.

[0292] The transmission device 60 is a spring 67. One end of the spring 67 presses against the pusher plate 50, and the other end of the spring 67 is inserted into the guide space 202 and presses against the wall of the guide space 202. Part of the spring 67 is located within the guide space 202. In some specific embodiments of this application, a limiting structure is provided on the wall of the guide space 202, and the spring 67 presses against the limiting structure.

[0293] The control component 70 is connected to the pusher plate 50. The control component 70 is indirectly connected to the spring 67 through the pusher plate 50, and can store the force of the spring 67 through the pusher plate 50.

[0294] After the rotating seat 20 and the compression seat 11 fix the mucosal tissue, the control component 70 drives the pusher plate 50 to move relative to the rotating seat 20. The pusher plate 50 compresses the spring 67, causing the spring 67 to store force. When the pusher plate 50 moves to the corresponding position, the anastomosis staple 40 enters the ejection position so that the pusher plate 50 can press against the anastomosis staple 40. Then, the external force applied to the control component 70 is removed. Since the spring 67 is in the stored state, the spring 67 drives the pusher plate 50 to move relative to the rotating seat 20. The pusher plate 50 pushes the anastomosis staple out of the installation space 21 so that the anastomosis staple 40 can suture the human body.

[0295] The above structure is simple. The pusher plate 50 can move only through the cooperation of the spring 67 and the control component 70. That is, there are fewer parts that drive the movement of the pusher plate 50, which makes the overall size of the product smaller. This allows the endoscopic staple release device to be smoothly inserted into or withdrawn from the human body, improving the product's flexibility and safety.

[0296] Example 9

[0297] like Figures 71 to 76 As shown, the transmission device 60 includes a first connecting cable 681 and at least one first guide transmission member 682.

[0298] The first guide transmission component 682 is fixed on the rotating seat 20.

[0299] One end of the first connecting cable 681 passes around the first guide transmission member 682 and connects to the pusher plate 50, while the other end of the first connecting cable 681 connects to the control member 70. In some embodiments of this application, the control member 70 and the first connecting cable 681 can be a single component or two separate components. When the control member 70 and the first connecting cable 681 are two separate components, the first connecting cable 681 is a flexible component such as a control belt or control rope.

[0300] After the rotating seat 20 and the squeezing seat 11 fix the mucosal tissue, the operating control component 70 is activated. The control component 70 drives the first connecting cable 681 to slide on the first guide transmission component 682. The first connecting cable 681 drives the pusher plate 50 to move relative to the rotating seat 20. The pusher plate 50 pushes the anastomosis staple 40 out of the installation space 21 so that the anastomosis staple 40 can suture the mucosal tissue.

[0301] The first guide transmission component 682 is equivalent to a fixed pulley. After the first connecting cable 681 is turned by the first guide transmission component 682, it can be parallel to the control component 70, thereby reducing the space occupied by the transmission device 60 and making reasonable use of the space, so that the overall size of the product is smaller. This allows the endoscopic staple release device to be smoothly inserted into or withdrawn from the human body, improving the flexibility and safety of the product.

[0302] In some embodiments of this application, a first energy storage and reset member 683 is provided between the pusher plate 50 and the rotating seat 20.

[0303] When the pusher plate 50 moves in the positive direction relative to the rotating seat 20, the first power storage and reset member 683 stores power. When the pusher plate 50 is controlled to rotate in the opposite direction relative to the rotating seat 20, the first power storage and reset member 683 releases the stored power, which helps the first power storage and reset member 683 return to the initial position, thereby reducing the difficulty of operation.

[0304] like Figure 77 and Figure 78As shown, in some embodiments of this application, the first guide transmission member 682 is a pulley, and the pulley is provided with two annular grooves 684, and the number of first connecting cables 681 is two.

[0305] A first connecting cable 681 is coiled in an annular groove 684 along a first direction, and another first connecting cable 681 is coiled in another annular groove 684 along a second direction. The two first connecting cables 681 are connected to the pusher plate 50 in opposite directions, with the first direction being opposite to the second direction. In some specific embodiments of this application, the two first connecting cables 681 are respectively connected to two opposite plates or opposite ends of the pusher plate 50.

[0306] When controlling the movement of one first connecting cable 681, the first connecting cable 681 drives the first guide transmission member 682 to rotate in a first direction relative to the rotating seat 20, and the rotating seat 20 drives the other first connecting cable 681 to move. During this process, one first connecting cable 681 is wound up and the other first connecting cable 681 is unwound. Conversely, when controlling the movement of the other first connecting cable 681, the other first connecting cable 681 drives the first guide transmission member 682 to rotate in a second direction relative to the rotating seat 20, and the rotating seat 20 drives the first connecting cable 681 to move. During this process, the other first connecting cable 681 is wound up and the first first connecting cable 681 is unwound.

[0307] Example 10

[0308] like Figures 79 to 85 As shown, the transmission device 60 includes a second connecting cable 691, a second guide transmission member 692, and a third guide transmission member 693.

[0309] The second guide transmission component 692 is fixed on the rotating seat 20, and the third guide transmission component 693 is fixed on the pusher plate 50.

[0310] One end of the second connecting cable 691 passes sequentially around the second guide transmission member 692 and the third guide transmission member 693 before connecting to the rotating seat 20. The other end of the second connecting cable 691 is connected to the control member 70. In some embodiments of this application, the control member 70 and the second connecting cable 691 can be a single component or two separate components. When the control member 70 and the second connecting cable 691 are two separate components, the second connecting cable 691 is a flexible component such as a control belt or control rope.

[0311] A second energy storage and reset component 694 is provided between the pusher plate 50 and the rotating seat 20.

[0312] After the rotating seat 20 and the squeezing seat 11 fix the mucosal tissue, the operating control component 70 is activated. The control component 70 drives the second connecting cable 691 to slide on the second guide transmission component 692. The first connecting cable 681 drives the pusher plate 50 to move relative to the rotating seat 20 through the third guide transmission component 693. The pusher plate 50 pushes the anastomosis staple 40 out of the installation space 21 so that the anastomosis staple 40 can suture the mucosal tissue.

[0313] The second guide transmission component 692 is equivalent to a fixed pulley, and the third guide transmission component 693 is equivalent to a movable pulley. On the one hand, after the second connecting cable 691 is turned by the second guide transmission component 692, it can be parallel to the control component 70, thereby reducing the space occupied by the transmission device 60 and making reasonable use of space, thus making the overall size of the product smaller. This allows the endoscopic staple release device to be smoothly inserted into or withdrawn from the human body, improving the product's flexibility and safety. On the other hand, the third guide transmission component 693 can reduce the pulling force required to drive the pusher plate 50 to move, thereby reducing the user's fatigue from using the product for a long time.

[0314] When the pusher plate 50 moves in the positive direction relative to the rotating seat 20, the second power storage and reset member 694 stores power. When the pusher plate 50 is controlled to rotate in the opposite direction relative to the rotating seat 20, the second power storage and reset member 694 releases the stored power, which helps the second power storage and reset member 694 return to the initial position, thereby reducing the difficulty of operation.

[0315] Example 11

[0316] like Figures 86 to 91 As shown, the transmission device 60 is a telescopic mechanism, which includes a telescopic assembly 601. The telescopic assembly 601 includes at least one cross link 6011. The cross link 6011 includes two connecting rods, which are hinged together at their middle parts.

[0317] One end of the telescopic mechanism is connected to the pusher plate 50, and the other end of the telescopic mechanism is connected to the control component 70.

[0318] After the rotating seat 20 and the squeezing seat 11 fix the mucosal tissue, the operating control component 70 is activated. The control component 70 drives the connecting rod to rotate relative to the rotating seat 20. The connecting rod drives the pusher plate 50 to move relative to the rotating seat 20. The pusher plate 50 pushes the anastomosis staple 40 out of the installation space 21 so that the anastomosis staple 40 can suture the mucosal tissue.

[0319] On the one hand, the cross link 6011 has a relatively simple structure, making it easy to manufacture and maintain. On the other hand, the cross link 6011 moves relatively smoothly, reducing vibration and impact during extension and retraction, thereby improving the reliability of the product.

[0320] In some embodiments of this application, the telescopic mechanism further includes an end rod assembly 602.

[0321] The end rod assembly 602 is located at one end of the telescopic assembly 601 adjacent to the pusher plate 50, and / or the end rod assembly 602 is located at one end of the telescopic assembly 601 adjacent to the control element 70.

[0322] The end rod assembly 602 includes two end connecting rods. One end of one end connecting rod is connected to one end of a connecting rod, and the other end of one end connecting rod is hinged to the end of the other end connecting rod.

[0323] The end rod assembly 602 reduces the two connection points of the telescopic assembly 601 to one, thus reducing the complexity of the connection and improving the overall stability and reliability.

[0324] In some embodiments of this application, a third energy storage and reset member 603 is provided between the pusher plate 50 and the rotating seat 20.

[0325] When the pusher plate 50 moves in the positive direction relative to the rotating seat 20, the third power storage and reset member 603 stores power. When the pusher plate 50 is controlled to rotate in the opposite direction relative to the rotating seat 20, the third power storage and reset member 603 releases the stored power, which helps the third power storage and reset member 603 return to the initial position, thereby reducing the difficulty of operation.

[0326] like Figures 1a to 91 As shown, the endoscopic suturing device provided in the second aspect of this application includes the endoscopic anastomosis staple release device and anastomosis staple as described in any of the above claims.

[0327] The staples 40 are installed in the mounting space 21 of the endoscopic staple release device, and the staples 40 can be squeezed and deformed.

[0328] The endoscopic suturing device provided in this application can effectively improve the accuracy and safety of staple puncture, so as to ensure that the staple effectively sutures the mucosal tissue, thereby ensuring safe and effective treatment of the mucosal tissue. In addition, the endoscopic suturing device only requires simple pushing and pulling movements to suture human mucosal tissue, without complicated other operation methods, reducing the operation difficulty of the product and thus effectively improving the comfort of the product.

[0329] like Figures 1a to 6b As shown, in some embodiments of this application, the extension direction of the guide groove 26 of the endoscopic staple release device is the same as the movement direction of the staple 40, so that the pusher plate 50 and the staple 40 are coplanar.

[0330] Before the endoscopic suturing device enters the human body, the pusher plate 50 overlaps with the staple 40, thereby completely concealing the transmission device 60 within the mating space 25, resulting in a smaller overall product size and improved user comfort. When it is necessary to push the staple out of the installation space 21, the pusher plate 50 is moved relative to the rotating seat 20. After the pusher plate 50 and the staple 40 are completely misaligned, the staple 40 is pushed by the elastic element, making the pusher plate 50 and the staple 40 coplanar. Then, during the reverse operation, the pusher plate 50 pushes the staple 40 out of the installation space 21.

[0331] like Figures 1a to 5 As shown, in some embodiments of this application, the number of anastomotic staples 40 is multiple, and the arrangement of multiple anastomotic staples 40 stacked together constitutes an anastomotic staple group.

[0332] The endoscopic suturing device also includes a needle box 91 and a second elastic element 92.

[0333] The needle box 91 is set in the installation space 21. The needle box 91 has an opening at one end to receive the cavity. The anastomosis staple group is set in the cavity. Among the multiple anastomosis staples 40, the anastomosis staple 40 that is farthest from the bottom wall of the cavity corresponds to the pusher plate 50. The bottom wall of the cavity refers to the cavity wall that is opposite to the opening of the cavity.

[0334] The second elastic element 92 is supported between the staple assembly and the bottom wall.

[0335] The process of ejecting a staple 40 from the needle holder 91 is essentially the same as in step three. After a staple 40 is sutured onto the mucosal tissue, the distance between the compression seat 11 and the rotating seat 20 is increased. Then, the operating control unit 70 controls the pusher plate 50 to exit the needle holder 91 via the transmission device 60. After the pusher plate 50 is completely exited from the needle holder 91, space is created for the staple 40. The next staple 40 moves upward under the action of the second elastic element 92 and becomes coplanar with the pusher plate 50. Then, the distance between the compression seat 11 and the rotating seat 20 is reduced. The operating control unit 70 then controls the pusher plate 50 via the transmission device 60 to push the staple 40 out of the mounting space 21 and suture it onto the mucosal tissue. This process is repeated to gradually release the staples 40. This structure enables continuous suturing of the mucosal tissue, reduces the number of times staples 40 need to be installed, and thus improves the efficiency of the product.

[0336] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
