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 digestive tract treatment auxiliary device and a puncture and suturing device assembly. Background Technology

[0002] With rising living standards, obesity is becoming increasingly prevalent, leading to various systemic and cardiovascular diseases, reducing quality of life, and even threatening lives. Currently, flexible endoscopic gastric wall folding surgery can effectively address this issue; however, its implementation presents challenges. Therefore, developing instruments for flexible endoscopic gastric wall folding surgery is of great significance. Existing techniques are limited in scope and require entirely new equipment, making it impossible to rely solely on existing endoscopes. Furthermore, during gastric wall puncture, the presence of organs or blood vessels at the puncture site cannot be determined, resulting in blind puncture and potential safety hazards. Additionally, the use of rigid sutures / needles for puncture requires addressing the issue of needle / needle bending. Utility Model Content

[0003] To achieve at least one of the above objectives, this application provides the following technical solution:

[0004] In a first aspect, embodiments of this application provide an endoscopic gastrointestinal treatment aid for use with an endoscope and a suture device, comprising: a mounting base having a through hole configured to cooperate with an endoscope and / or a suture device and / or an endoscope accessory; and a stop portion disposed at an end of the mounting base and extending axially along the through hole, the stop portion being configured to support gastrointestinal tissue.

[0005] In some embodiments, the mounting base is provided with a first movable structure, and the abutment is provided with a second movable structure that cooperates with the first movable structure, and the abutment is movable relative to the mounting base.

[0006] In some embodiments, a reset member is provided between the mounting base and the blocking portion.

[0007] In some embodiments, the reset element is a spring.

[0008] In some embodiments, the abutment is provided with a clearance hole, which is configured to allow the suture needle of the suture device to pass through.

[0009] In some embodiments, the mounting base has a plurality of parallel through holes.

[0010] In some embodiments, the endoscopic gastrointestinal treatment aid further includes: a first guide, the first guide including a first connector and an arc-shaped channel, the outlet of the arc-shaped channel facing the abutment, the arc-shaped channel being positioned opposite the abutment, the arc-shaped channel being configured to guide a suture needle to the abutment, and the first connector being configured to engage with an endoscope.

[0011] In some embodiments, the endoscopic gastrointestinal treatment aid further includes: a second guide having a guide channel positioned opposite to the abutment; a guide tube including a deformable section and a compression section connected in sequence, the compression section passing through the guide channel and protruding from the guide channel; and a control cable connected to the compression section, the control cable being configured to control the compression section to move toward the abutment so that the end of the compression section engages with the abutment to clamp gastrointestinal tissue.

[0012] In some embodiments, the second guide is disposed on the mounting base, and the guide channel communicates with the through hole.

[0013] In some embodiments, the second guide further includes a second connector configured to be fitted onto the endoscope.

[0014] In some embodiments, a support groove is provided at one end of the guide channel away from the mounting base, the guide channel is connected to the support groove, and the support groove is configured to accommodate the extrusion section.

[0015] In some embodiments, the mounting base is provided with a receiving groove, which is disposed adjacent to the abutment and communicates with the through hole, and the receiving groove is configured to receive digestive tract tissue.

[0016] In some embodiments, the endoscopic gastrointestinal treatment aid further includes: an installation tube connected to the mounting base and communicating with the through hole.

[0017] Compared with existing technologies, the above technical solution has the following advantages:

[0018] After the endoscopic gastrointestinal treatment accessory is inserted into the body along with the endoscope, a clamping element (an existing endoscopic accessory) passes through the through-hole of the treatment accessory to pull the gastrointestinal tissue to be punctured, positioning the tissue on the blocking part. Other structures (such as the endoscope, a first guide, or a second guide) cooperate with the blocking part to clamp and compress the tissue. Then, other structures guide and position the suture device so that it can puncture and suture the gastrointestinal tissue. The endoscopic gastrointestinal treatment accessory can have multiple through-holes; therefore, before puncture and suturing, an endoscopic ultrasound is used to pull the tissue through the through-holes. The pulled-up digestive tract tissue is scanned to assess the presence of organs and major blood vessels within and around the tissue. Puncture and suturing are performed only after safety is ensured, thus avoiding damage to organs and major blood vessels during the puncture and suturing process and improving operational safety. In addition, the endoscopic digestive tract treatment accessory has a simple structure and relatively simple manufacturing process, reducing costs. At the same time, through the cooperation of other structures (other structures are endoscopes, first guides, or second guides) and the blocking part, the problems of effective puncture by the suture device and hard suture needles passing through the curved section of the treatment accessory are effectively solved, making the operation efficient and reliable.

[0019] Secondly, embodiments of this application provide a puncture suture assembly, comprising: the aforementioned endoscopic gastrointestinal treatment aid; and a suture, wherein the suture needle of the suture is inserted into a through-hole of the mounting base and extends to an end of the mounting base, the suture being configured to secure a suture to gastrointestinal tissue.

[0020] In some embodiments, the suture needle is a needle tube configured to pass a suture through digestive tract tissue.

[0021] In some embodiments, the puncture suture assembly further includes a suture element disposed within the needle tube, the suture element including a suture and one or more limiting structures, the suture element being configured to suture digestive tract tissue.

[0022] In some embodiments, the suture device further includes a drive mechanism connected to the suture needle, the drive mechanism being configured to drive the suture needle to move relative to the mounting base.

[0023] In some embodiments, the drive device includes a threaded rod and a movable member, the movable member being threadedly connected to the threaded rod, and the threaded rod being rotatable relative to the movable member.

[0024] Compared with existing technologies, the above technical solution has the following advantages:

[0025] After the puncture suture device is inserted into the human body, the digestive tract tissue to be punctured and sutured is first scanned by an endoscopic ultrasound to avoid organs and blood vessels outside the digestive tract and lumen, so as to ensure that organs and major blood vessels are not damaged during the puncture suture process, thus improving the safety of the puncture suture process. In addition, the puncture suture device has a simple structure and is easy to operate. Existing endoscopic visualization puncture and release sutures can be used, without the need for new equipment.

[0073] In the description of this application, "multiple" means two or more (including two), unless otherwise expressly and specifically defined.

[0074] In the description of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, and other dimensions of various components in the embodiments of this application shown in the drawings, as well as the overall thickness, length, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0075] like Figures 1 to 27 As shown, an endoscopic digestive tract treatment aid 100 provided in the first aspect of this application for use with an endoscope 300 and a suture device 200 includes: a mounting base 10 and a stop portion 20.

[0076] Mounting base 10 has a through hole 11 therethrough, which is configured to mate with endoscope 300 and / or stapler 200 and / or endoscope accessory 600.

[0077] The abutment 20 is provided at the end of the mounting base 10 and extends axially along the through hole 11. The abutment 20 is configured to support the digestive tract tissue 400.

[0078] After the endoscopic digestive tract treatment aid 100 is inserted into the human body along with the endoscope 300, it is extended into the human body through the through hole 11 of the treatment aid by the clamping member (endoscope accessory 600) to pull the digestive tract tissue 400 so that the digestive tract tissue 400 is positioned on the blocking part 20. Then, the endoscope 300 (ultrasound endoscope) is used to scan the pulled tissue to be punctured through the through hole 11 of the treatment aid. After ruling out the absence of organs and major blood vessels in and around the tissue, the digestive tract tissue 400 is clamped and squeezed by other structures (other structures are the endoscope 300, the first guide 40 or the second guide 51) in cooperation with the blocking part 20. Then, the suture device 200 is used to suture the digestive tract tissue 400. In the above process, the endoscopic digestive tract treatment aid 100 can achieve visual operation, thereby avoiding damage to organs and blood vessels by the suture device 200 during puncture and suturing, which greatly improves the safety of the puncture and suturing process.

[0079] In addition, the endoscopic digestive tract treatment auxiliary component 100 has a simple structure and a relatively simple manufacturing process, which reduces labor costs and equipment wear and tear costs. At the same time, through the cooperation of other structures (other structures are endoscope 300, first guide 40 or second guide 51) with the blocking part 20, the problem of effective puncture and bending of the suture device 200 is effectively solved, making the operation efficient and reliable.

[0080] like Figures 5 to 10 As shown, in one embodiment of this application, a first movable structure 12 is provided on the mounting base 10, and a second movable structure 21 that cooperates with the first movable structure 12 is provided on the abutment 20, allowing the abutment 20 to move relative to the mounting base 10. In another embodiment of this application, a reset member 30 is provided between the mounting base 10 and the abutment 20. In a specific embodiment of this application, the reset member 30 is a spring. The cooperation between the first movable structure 12 and the second movable structure 21 is a guide rail and guide groove cooperation. Those skilled in the art should understand that, in addition to the above-mentioned structures, any structure that enables the abutment 20 to slide relative to the mounting base 10 is acceptable, and will not be listed here.

[0081] When the clamping member drags a large amount of digestive tract tissue 400 between the blocking part 20 and other structures, the digestive tract tissue 400 squeezes the blocking part 20, causing the blocking part 20 to move relative to the mounting base 10 to create more tissue-accommodating space, thereby ensuring that there is more digestive tract tissue 400 between the blocking part 20 and other structures, so as to ensure effective suturing of the digestive tract tissue 400.

[0082] like Figures 1 to 27 As shown, in one embodiment of this application, the blocking part 20 is provided with a clearance hole 22, which is configured to allow the suture needle of the suturer 200 to pass through.

[0083] The clearance hole 22 provides puncture space for the suture needle, enabling the suture needle to more effectively puncture the digestive tract tissue 400.

[0084] like Figures 1 to 4 As shown, in one embodiment of this application, the mounting base 10 has a plurality of parallel through holes 11.

[0085] Different endoscopes and endoscope accessories can be inserted into different through holes 11 to meet the different needs and safety requirements of minimally invasive endoscopic surgery, making the application wider and safer.

[0086] like Figures 11 to 13 As shown, in one embodiment of this application, the endoscopic gastrointestinal treatment aid 100 further includes a first guide 40.

[0087] The first guide 40 includes a first connecting seat 41 and an arc-shaped channel 42. The outlet of the arc-shaped channel 42 faces the blocking part 20. The arc-shaped channel 42 is positioned opposite to the blocking part 20. The arc-shaped channel 42 is configured to guide the suture needle to the blocking part 20. The first connecting seat 41 is configured to connect with the endoscope 300.

[0088] The endoscope 300 (ultrasound endoscope) scans the site requiring puncture and suturing. After ruling out the presence of nearby organs and major blood vessels, the clamping element (endoscope accessory 600) passes through the through-hole 11 and extends into the body to pull the digestive tract tissue 400. This pulls the digestive tract tissue 400 between the end of the arc-shaped channel 42 and the stop 20, achieving clamping and compression of the digestive tract tissue 400 by the arc-shaped channel 42 and the stop 20. Then, the suture device 200 is inserted into the guide tube 52 to suture the digestive tract tissue 400. The arc-shaped channel 42 guides the suture to the digestive tract tissue 400, allowing the suture to reach the required suturing site more precisely, avoiding suture position deviation, and ensuring the suture needle is essentially perpendicular to the tissue to be punctured. This facilitates precise suturing of the digestive tract tissue 400, making the suturing operation more accurate. Furthermore, the product has a simple structure, requiring less operating space, especially in situations with limited operating space.

[0089] like Figures 14 to 27 As shown, in one embodiment of this application, the endoscopic gastrointestinal treatment aid 100 further includes: a second guide 51, a guide tube 52, and a control cable 53.

[0090] The second guide member 51 has a guide channel 511, and the guide channel 511 is positioned opposite to the position of the abutment part 20.

[0091] The guide tube 52 includes a deformable section 521 and a pressing section 522 connected in sequence. The pressing section 522 passes through the guide channel 511 and protrudes from the guide channel 511.

[0092] The control cable 53 is connected to the compression section 522. The control cable 53 is configured to control the compression section 522 to move toward the stop 20 so that the end of the compression section 522 cooperates with the stop 20 to clamp the digestive tract tissue 400.

[0093] The operating steps of the above device are as follows:

[0094] 1. Connect the endoscopic digestive tract treatment auxiliary component 100 to the endoscope 300, so that the endoscopic digestive tract treatment auxiliary component 100 enters the human body together with the endoscope 300 to reach the digestive tract tissue to be punctured and sutured.

[0095] 2. The digestive tract tissue 400 is pulled through the working channel or through-hole 11 of the endoscope using a clamping device (endoscope accessory 600) to position the digestive tract tissue 400 on the blocking part 20. Then, the endoscope 300 (ultrasound endoscope) scans the pulled tissue through the through-hole 11 to assess the presence of organs and blood vessels within and near the tissue, ensuring the safety of the puncture and suturing. It should be noted that, depending on the requirements of minimally invasive endoscopic surgery, this step can be selected for visualization. To implement this step, in some embodiments, multiple through-holes 11 are provided to allow the endoscope 300 and endoscope accessory 600 to pass through simultaneously.

[0096] 3. Insert the suture device 200 into the guide tube 52, positioning the stiffer suture needle (made of a stiffer material to ensure penetration of the tissue) in the compression section of the guide tube 52 and avoiding the deformation section. This effectively solves the problems of the stiff suture needle going too far into the bending section and the suture needle not being able to bend.

[0097] 4. The digestive tract tissue 400 is pulled onto the stop portion 20 by the clamp (endoscope accessory 600), and then the control cable 53 is dragged so that the control cable 53 controls the guide tube 52 to bend towards the stop portion 20, so that the compression section 522 presses the digestive tract tissue 400 against the stop portion 20, so that the outlet of the guide tube 52 faces the digestive tract tissue 400. Then the digestive tract tissue 400 is sutured by the suture needle. Since the suture needle is basically perpendicular to the digestive tract tissue 400 to be punctured, it helps to accurately suture the digestive tract tissue 400.

[0098] like Figures 14 to 19 As shown, in a specific embodiment of this application, the second guide 51 is disposed on the mounting base 10, and the guide channel 511 communicates with the through hole 11. This structure has a larger tissue accommodating space and can pull enough tissue to be sutured into the endoscopic digestive tract treatment auxiliary component 100 to meet the application needs of some endoscopic minimally invasive surgeries.

[0099] In addition, the second guide component 51 can be integrally cast with the mounting base 10 using a casting process, thereby ensuring the overall mechanical strength of the product and ensuring its reliability.

[0100] like Figures 20 to 24 As shown, in another specific embodiment of this application, the second guide 51 further includes a second connecting seat 512, which is configured to be sleeved on the endoscope 300 and can pass through the through hole 11 to perform operations.

[0101] The second guide 51 and the mounting base 10 can be respectively engaged with the endoscope 300. This structure and engagement method occupy less space to meet the needs of some minimally invasive endoscopic surgeries.

[0102] like Figures 14 to 27 As shown, in one embodiment of this application, a support groove 513 is provided on the end of the guide channel 511 away from the mounting base 10. The guide channel 511 is connected to the support groove 513, and the support groove 513 is configured to accommodate the extrusion section 522.

[0103] The control cable 53 bends the guide tube 52. When the compression section 522 enters the support groove 513 and presses against the bottom of the groove, the compression section 522 cannot move due to the support of the groove bottom. This prevents the compression section 522 from moving too far and causing improper engagement between the guide tube 52 and the stop part 20. This ensures that the guide tube 52 can engage with the stop part 20, thus guaranteeing more effective suturing of the digestive tract tissue 400. It should be noted that in some embodiments, the guide tube 52 communicates sequentially with the through hole 11 of the mounting base 10, the working channel of the endoscope, or the mounting tube 60. The guide tube 52 can move relative to the through hole 11.

[0104] like Figures 25 to 27 As shown, in one embodiment of this application, the mounting base 10 is provided with a receiving groove 13, which is located adjacent to the abutment 20 and communicates with the through hole 11. The receiving groove 13 is configured to receive digestive tract tissue 400.

[0105] The clamping element (endoscope accessory 600) can pull the digestive tract tissue 400 into the receiving groove 13 so that there is more digestive tract tissue 400 between the other structure (other structure is endoscope 300, first guide 40 or second guide 51) and the blocking part 20, that is, to ensure that enough tissue to be punctured and sutured is pulled in to meet the needs of some minimally invasive surgery, thereby ensuring effective suturing of the digestive tract tissue 400.

[0106] like Figures 1 to 4 , Figure 19As shown, in one embodiment of this application, the endoscopic gastrointestinal treatment aid 100 further includes an installation tube 60. Specifically, the number of installation tubes 60 may be one or more, wherein multiple installation tubes 60 are arranged in parallel.

[0107] The mounting tube 60 is connected to the mounting base 10 and communicates with the through hole 11.

[0108] The mounting tube 60 provides protection for the instruments and allows endoscopes, endoscope accessories, and sutures to pass through. In some embodiments, the mounting tube 60 is larger, with its distal end directly connected and fixed to the mounting base 10, and its end located outside the body. Therefore, the surgeon can hold its end to manipulate the treatment aids.

[0109] Several embodiments of this application are described in detail below with reference to the accompanying drawings.

[0110] Example 1

[0111] like Figures 1 to 4 As shown, the endoscopic digestive tract treatment aid 100 includes: a mounting base 10, a mounting tube 60, and a blocking part 20.

[0112] Mounting base 10 has two through holes 11 extending through it, which are used to cooperate with endoscope 300 and endoscope accessory 600 (clamping member), respectively, and the suture 200 is located in the working channel of endoscope 300.

[0113] The abutment 20 is provided at the end of the mounting base 10 and extends axially along the through hole 11. The abutment 20 is configured to support the digestive tract tissue 400.

[0114] The mounting tube 60 is connected to the mounting base 10 and communicates with the through hole 11.

[0115] The usage process of the above products is as follows:

[0116] After the endoscopic digestive tract treatment accessory 100 is inserted into the human body along with the endoscope 300, the clamping element (endoscope accessory 600) passes through the through hole 11 to pull the digestive tract tissue 400, positioning the digestive tract tissue 400 on the blocking part 20. Then, the endoscope 300 (ultrasound endoscope) passes through the installation tube 60 to scan the site requiring puncture and suturing. After ruling out the absence of organs and major blood vessels in or near the tissue, the suture device 200 is inserted into the working channel of the endoscope 300 to its foremost tip, so that the stiffer suture needle of the suture device 200 is located at the non-curved part of the endoscope 300's forehead. Then, the digestive tract tissue 400 is clamped and compressed by the cooperation of the curved part of the endoscope 300's forehead and the blocking part 20, and finally, the suture device 200 is used to puncture and suture the digestive tract tissue 400.

[0117] Example 2

[0118] like Figures 5 to 10 As shown, the endoscopic digestive tract treatment aid 100 includes: a mounting base 10 and a blocking part 20.

[0119] Mounting base 10 has two through holes 11 extending through it, which are used to cooperate with endoscope 300 and endoscope accessory 600 (clamping member), respectively, and the suture 200 is located in the working channel of endoscope 300.

[0120] A stop portion 20 is provided at the end of the mounting base 10 and extends axially along the through hole 11. The stop portion 20 is configured to support the digestive tract tissue 400. The stop portion 20 is movable relative to the mounting base 10 through the cooperation of the first movable structure 12 and the second movable structure 21.

[0121] A reset element 30 is provided between the mounting base 10 and the abutment 20. Specifically, the reset element 30 is a spring. This structure moves passively by compressive force, eliminating the need for a corresponding drive structure and simplifying the design.

[0122] The process of using the endoscopic digestive tract treatment aid 100 is basically the same as in Example 1. The difference is that in some minimally invasive endoscopic surgeries, when there is a large amount of digestive tract tissue 400 being pulled, the digestive tract tissue 400 squeezes the blocking part 20, causing the blocking part 20 to move relative to the mounting base 10 to increase the accommodating space and expand the puncture stroke, and then the suture device 200 is used to suture the digestive tract tissue 400.

[0123] Example 3

[0124] like Figures 11 to 13 As shown, the endoscopic digestive tract treatment aid 100 includes: a mounting base 10, a first guide 40, and a blocking part 20.

[0125] Mounting base 10 has two through holes 11 extending through it, which are used to cooperate with endoscope 300 and endoscope accessory 600 (clamping member), respectively, and the suture 200 is located in the working channel of endoscope 300.

[0126] The abutment 20 is provided at the end of the mounting base 10 and extends axially along the through hole 11. The abutment 20 is configured to support the digestive tract tissue 400.

[0127] The first guide member 40 includes a first connecting seat 41 and an arc-shaped channel 42. The outlet of the arc-shaped channel 42 faces the abutment 20, and the arc-shaped channel 42 is positioned opposite to the abutment 20. The arc-shaped channel 42 is configured to guide the suture needle to the abutment 20. The first connecting seat 41 is configured to connect with the endoscope 300. Unlike embodiments one and two, in this embodiment, it is not necessary to guide the endoscope 300 by bending its tip; instead, the first guide member 40 guides the suture needle of the stapler 200 towards the abutment 20 for puncture and suturing. This structure is simple, requires less operating space, and the suture needle needs a certain degree of elasticity to pass through the arc-shaped channel 42.

[0128] Example 4

[0129] like Figures 14 to 18 As shown, the endoscopic digestive tract treatment aid 100 includes: a mounting base 10, a blocking part 20, a second guide 51, a guide tube 52, and a control cable 53.

[0130] Mounting base 10 has two through holes 11 extending through it. One through hole 11 is fitted and fixed to the front end of endoscope 300, and the other through hole 11 is used in conjunction with suture device 200. Endoscope accessory 600 (existing clamp) is located in the working channel of endoscope 300 to clamp and pull digestive tract tissue.

[0131] The abutment 20 is provided at the end of the mounting base 10 and extends axially along the through hole 11. The abutment 20 is configured to support the digestive tract tissue 400.

[0132] The guide tube 52 includes a deformable section 521 and a compression section 522 connected in sequence. The compression section 522 passes through the guide channel 511 and protrudes from the guide channel 511. The guide channel 511 communicates with the through hole 11 of the mounting base 10 and with the mounting tube 60 for the suture device 200 to pass through. The mounting tube 60 is arranged in parallel with the endoscope 300.

[0133] The control cable 53 is connected to the compression section 522. The control cable 53 is configured to control the compression section 522 to move toward the stop 20 so that the end of the compression section 522 cooperates with the stop 20 to clamp the digestive tract tissue 400.

[0134] After the endoscopic digestive tract treatment accessory 100 is inserted into the human body along with the endoscope 300, the suture device 200 is inserted into the guide tube 52, so that its relatively stiff suture needle is located in the compression section of the guide tube 52 and avoids the deformation section. Then, the digestive tract tissue 400 is pulled to the blocking part 20 by the clamping device (endoscope accessory 600). Then, the control cable 53 is dragged, so that the control cable 53 controls the guide tube 52 to bend in the direction closer to the blocking part 20, so that the compression section 522 presses the digestive tract tissue 400 against the blocking part 20, and the suture needle of the suture device 200 is basically perpendicular to the tissue to be punctured for puncture and suturing.

[0135] Example 5

[0136] like Figure 19 As shown, the endoscopic digestive tract treatment aid 100 includes: a mounting base 10, a blocking part 20, a second guide 51, a mounting tube 60, a guide tube 52, and a control cable 53.

[0137] The difference from Embodiment 4 is that a thicker outer diameter mounting tube 60 is directly connected and fixed to the mounting base 10 at its distal end, with its end located outside the body. The surgeon can manipulate the treatment aid by holding its end. The endoscope 300 can pass through the mounting tube 60 and the through hole 11 of the mounting base 10, moving back and forth within the through hole. After the endoscope accessory 600 (existing clamping device) located in the working channel of the endoscope 300 clamps the tissue, together with the movable endoscope 300, it pulls the clamped tissue into the through hole 11 of the mounting base 10 and the mounting tube 60, with a longer traction stroke to pull up a sufficient amount of tissue to be punctured and sutured. The remaining structure is the same as in Embodiment 4.

[0138] Example 6

[0139] like Figures 21 to 24 As shown, the endoscopic digestive tract treatment aid 100 includes: a mounting base 10, a blocking part 20, a second guide 51, a guide tube 52, and a control cable 53.

[0140] The second guide member 51 also includes a second connecting seat 512, which is configured to be sleeved on the endoscope 300, and the guide tube 52 communicates with the working channel of the endoscope 300.

[0141] Mounting base 10 has two through holes 11 extending through it, which are used to engage with endoscope 300 and endoscope accessory 600 (existing clamping device), respectively. Suturer 200 is located in the working channel and guide tube 52 of endoscope 300.

[0142] A stop portion 20 is provided at the end of the mounting base 10 and extends axially along the through hole 11. The stop portion 20 is configured to support the digestive tract tissue 400. The stop portion 20 is movable relative to the mounting base 10 through the cooperation of the first movable structure 12 and the second movable structure 21.

[0143] A reset element 30 is provided between the mounting base 10 and the blocking part 20. Specifically, the reset element 30 is a spring.

[0144] The guide tube 52 includes a deformable section 521 and a pressing section 522 connected in sequence. The pressing section 522 passes through the guide channel 511 and protrudes from the guide channel 511.

[0145] The control cable 53 is connected to the compression section 522. The control cable 53 is configured to control the compression section 522 to move toward the stop 20 so that the end of the compression section 522 cooperates with the stop 20 to clamp the digestive tract tissue 400.

[0146] The mounting tube 60 is connected to the mounting base 10 and communicates with the through hole 11.

[0147] Example 7

[0148] like Figures 25 to 27 As shown, the endoscopic digestive tract treatment aid 100 includes: a mounting base 10, a blocking part 20, a second guide 51, a guide tube 52, and a control cable 53.

[0149] The mounting base 10 has three through holes 11, which are used in conjunction with the endoscope accessory 600 (existing clamp), the endoscope 300, and the suture device 200, respectively. The endoscope accessory 600 (clamp) passes through the mounting tube 60 and the through holes 11. The mounting base 10 is provided with a receiving groove 13, which is located adjacent to the abutment 20 and communicates with the corresponding through hole 11 of the endoscope accessory 600 (clamp). The receiving groove 13 is configured to receive the digestive tract tissue 400 to be sutured, so as to pull up a sufficient amount of tissue to be punctured and sutured.

[0150] The abutment 20 is provided at the end of the mounting base 10 and extends axially along the through hole 11. The abutment 20 is configured to support the digestive tract tissue 400.

[0151] The guide tube 52 includes a deformable section 521 and a pressing section 522 connected in sequence. The pressing section 522 passes through the guide channel 511 and protrudes from the guide channel 511.

[0152] The control cable 53 is connected to the compression section 522. The control cable 53 is configured to control the compression section 522 to move toward the stop 20 so that the end of the compression section 522 cooperates with the stop 20 to clamp the digestive tract tissue 400.

[0153] like Figure 3 , Figure 4 ,to Figure 10 ,and Figure 13 As shown, the puncture suture assembly provided in the second aspect of this application includes: the endoscopic gastrointestinal treatment aid 100 described above and the suture 200.

[0154] The suture needle of the suture device 200 is inserted into the through hole 11 of the mounting base 10 and extends to the end of the mounting base 10. The suture device 200 is configured to fix the suture to the digestive tract tissue 400.

[0155] The puncture suture assembly has a simple structure and is easy to operate. It can be visualized and released using existing endoscopes under 300-degree visualization, without the need for new equipment.

[0156] like Figure 3 , Figure 4 , Figure 10 , Figure 13 and Figure 28 As shown, in one embodiment of this application, the suture needle is a needle tube configured to pass the suture through digestive tract tissue 400.

[0157] When the suture passes through the needle, the needle itself guides the suture, allowing it to reach the desired area more precisely, avoiding misalignment and facilitating accurate suturing of the digestive tract tissue. This makes the suturing operation more precise. Furthermore, in situations with limited space, using a needle to assist suturing allows the operator to better control the direction and depth of the suture. The needle also serves as a temporary support structure, helping to stabilize the suture site and making the suturing process smoother.

[0158] like Figure 3 , Figure 4 , Figure 10 , Figure 13 and Figure 28 As shown, in one embodiment of this application, the puncture suture assembly further includes a suture.

[0159] The suture is placed inside the needle tube and is configured to suture digestive tract tissue 400.

[0160] The suture material can be a suture needle or a suture post 500. For example... Figure 29 As shown, the suture post 500 includes at least two fixation posts 501 and a connecting line 502 connecting the two fixation posts 501. Depending on the specific surgical needs, multiple fixation posts 501 can be connected in series on the connecting line 502 / suture 502 to achieve continuous puncture suturing.

[0161] If the suture material can be a suture needle, after the needle tube passes through the digestive tract tissue 400, the suture material, carrying the suture 502, punctures the digestive tract tissue 400 back and forth through the needle tube to suture the digestive tract tissue 400. For example... Figure 30 and Figure 31 As shown, if the suture piece can be a suture post 500, after the needle passes through the digestive tract tissue 400, a fixing post 501 is pushed out of the needle. Then the needle is withdrawn. Since the fixing post 501 is limited by the human body component, the suture post 500 is gradually pulled out of the needle during the withdrawal process until the next fixing post 501 comes out of the needle. The two fixing posts 501 are located on both sides of the digestive tract tissue 400 respectively. Then the connecting line 502 is pulled back so that the two fixing posts 501 suture the human digestive tract tissue 400 together.

[0162] like Figure 28 As shown, in one embodiment of this application, the suture 200 further includes a drive device 700.

[0163] The drive device 700 is connected to the suture needle and is configured to drive the suture needle to move relative to the mounting base 10. In one specific embodiment of this application, the drive device 700 includes a threaded rod and a movable member, the movable member being screwed to the threaded rod, and the threaded rod being rotatable relative to the movable member.
