[0074] In the description of the present application, the same reference numerals represent 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 the present application shown in the drawings, as well as the overall thickness, length and other dimensions of the integrated device are only exemplary descriptions and should not constitute any limitation to the present application.

[0075] like Figures 1 to 27 As shown, the embodiment of the first aspect of the present application provides an endoscopic digestive tract treatment auxiliary component 100 for use with an endoscope 300 and a stapler 200 , which includes: a mounting seat 10 and a resisting portion 20 .

[0076] The mounting seat 10 has a through hole 11 therethrough, and the through hole 11 is configured to be used in conjunction with the endoscope 300 and / or the stapler 200 and / or the endoscope accessory 600 .

[0077] The blocking portion 20 is disposed at an end of the mounting seat 10 and extends along the axial direction of the through hole 11 . The blocking portion 20 is configured to support the digestive tract tissue 400 .

[0078] After the endoscopic digestive tract treatment auxiliary part 100 enters the human body together with the endoscope 300, it is extended into the human body through the clamping part (endoscopic accessory 600) through the through hole 11 of the treatment auxiliary part to pull the digestive tract tissue 400 so that the digestive tract tissue 400 is located on the resisting part 20. Then, the endoscope 300 (ultrasonic endoscope) is used to pass through the through hole 11 of the treatment auxiliary part to scan the pulled tissue to be punctured. After excluding the organs and large blood vessels in and near the tissue, the digestive tract tissue 400 is clamped and squeezed by other structures (the other structures are the endoscope 300, the first guide part 40 or the second guide part 51) and the resisting part 20, and then the digestive tract tissue 400 is sutured by the suturing device 200. In the above process, the endoscopic digestive tract treatment auxiliary part 100 can realize visual operation, thereby avoiding the situation where the suturing device 200 damages the organs and blood vessels during the puncture and suturing process, which greatly improves the safety of the puncture and suturing process.

[0079] In addition, the endoscopic gastrointestinal treatment auxiliary part 100 has a simple structure and a relatively simple production process, which reduces labor costs and equipment loss costs. At the same time, through the cooperation of other structures (the other structures are the endoscope 300, the first guide member 40 or the second guide member 51) and the resistance part 20, the effective puncture and bending problems of the stapler 200 are effectively solved, making the operation efficient and reliable.

[0080] like Figures 5 to 10 As shown, in one embodiment of the present application, a first movable structure 12 is provided on the mounting seat 10, and a second movable structure 21 that cooperates with the first movable structure 12 is provided on the resisting portion 20, and the resisting portion 20 can move relative to the mounting seat 10. In another embodiment of the present application, a reset member 30 is provided between the mounting seat 10 and the resisting portion 20. In a specific embodiment of the present application, the reset member 30 is a spring. The cooperation between the first movable structure 12 and the second movable structure 21 is the cooperation between the guide rail and the guide groove. Those skilled in the art should understand that in addition to the above-mentioned structure, any structure as long as it can realize the sliding of the resisting portion 20 relative to the mounting seat 10 is acceptable, and they will not be listed one by one here.

[0081] When the clamping member drags more digestive tract tissue 400 to between the resisting portion 20 and other structures, the digestive tract tissue 400 squeezes the resisting portion 20, causing the resisting portion 20 to move relative to the mounting seat 10 to free up a larger tissue accommodating space, thereby allowing more digestive tract tissue 400 to be between the resisting portion 20 and other structures to ensure effective suturing of the digestive tract tissue 400.

[0082] like Figures 1 to 27 As shown, in one embodiment of the present application, a avoidance hole 22 is provided on the resisting portion 20 , and the avoidance hole 22 is configured to allow a suture needle of the suture device 200 to pass through.

[0083] The avoidance hole 22 provides a puncture space for the suture needle, so that the suture needle can puncture the digestive tract tissue 400 more effectively.

[0084] like Figures 1 to 4 As shown, in one embodiment of the present application, the mounting seat 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 different usage and safety requirements of endoscopic minimally invasive surgeries, making the application wider and safer.

[0086] like Figures 11 to 13 As shown, in one embodiment of the present application, the endoscopic digestive tract treatment auxiliary component 100 also includes: a first guide component 40.

[0087] The first guide member 40 includes a first connecting seat 41 and an arc channel 42. The outlet of the arc channel 42 faces the resisting portion 20. The setting position of the arc channel 42 is opposite to the position of the resisting portion 20. The arc channel 42 is configured to guide the suture needle to the resisting portion 20. The first connecting seat 41 is configured to be connected to the endoscope 300.

[0088] The endoscope 300 (ultrasound endoscope) scans the part that needs to be punctured and sutured. After excluding the presence of organs and large blood vessels nearby, the clamp (endoscopic accessory 600) is extended into the human body through the through hole 11 to pull the digestive tract tissue 400, so that the digestive tract tissue 400 is pulled between the end of the arc channel 42 and the stopper 20, so as to achieve the clamping and squeezing of the digestive tract tissue 400 by the arc channel 42 and the stopper 20, and then the suture device 200 is inserted into the guide tube 52 to suture the digestive tract tissue 400. The arc channel 42 can guide the suture piece to the digestive tract tissue 400, so that the suture piece can reach the part that needs to be sutured more accurately, avoid suture position deviation, and make the suture needle basically perpendicular to the tissue to be punctured, which helps to accurately suture the digestive tract tissue 400 and make the suture operation more accurate. In addition, the product has a simple structure, especially when the operating space is limited, the required operating space is small.

[0089] like Figures 14 to 27 As shown, in one embodiment of the present application, the endoscopic digestive tract treatment auxiliary component 100 also includes: a second guide member 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 disposed at a position opposite to the stopper 20 .

[0091] The guide tube 52 includes a deformation section 521 and an extrusion section 522 which are connected in sequence. The extrusion section 522 passes through the guide channel 511 and protrudes out of the guide channel 511 .

[0092] The control cable 53 is connected to the extrusion section 522 , and is configured to control the extrusion section 522 to move toward the resisting portion 20 , so that the end of the extrusion section 522 cooperates with the resisting portion 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 device 100 to the endoscope 300, so that the endoscopic digestive tract treatment auxiliary device 100 enters the human body together with the endoscope 300 to reach the digestive tract tissue to be punctured and sutured.

[0095] 2. Pull the digestive tract tissue 400 through the working channel or through hole 11 of the endoscope through the clamp (endoscope accessory 600), so that the digestive tract tissue 400 is located on the resisting portion 20. Then, the endoscope 300 (ultrasound endoscope) passes through the through hole 11 to scan the pulled tissue to evaluate whether there are organ blood vessels in and near the tissue to ensure the safety of puncture and suturing. It should be noted that according to the requirements of endoscopic minimally invasive surgery, the operation of this step can be selected to implement visualization operation. To implement the operation of this step, in some embodiments, there are multiple through holes 11 for the endoscope 300 and the endoscope accessory 600 to pass through at the same time.

[0096] 3. Insert the suture device 200 into the guide tube 52, so that the harder suture needle (to ensure the penetration of the suture needle into the tissue, the suture needle is made of a harder material) is located in the extrusion section of the guide tube 52 and avoids the deformation section. This effectively solves the problem that the hard suture needle passes through the bending section and the suture needle cannot be bent.

[0097] 4. Pull the digestive tract tissue 400 onto the resisting portion 20 through the clamping piece (endoscope accessory 600), and then drag the control cable 53 so that the control cable 53 controls the guide tube 52 to bend toward the resisting portion 20, so that the extrusion section 522 presses the digestive tract tissue 400 against the resisting portion 20, even if the outlet of the guide tube 52 is toward the digestive tract tissue 400, and then suture the digestive tract tissue 400 through 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 the present application, the second guide member 51 is arranged on the mounting seat 10, and the guide channel 511 is communicated with the through hole 11. This structural method has a larger tissue accommodating space and can pull sufficient tissue to be sutured into the endoscopic gastrointestinal treatment auxiliary member 100 to meet the application requirements of some endoscopic minimally invasive surgeries.

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

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

[0101] The second guide member 51 and the mounting seat 10 can be matched with the endoscope 300 respectively. This structure and matching method occupies a smaller space to meet the needs of some endoscopic minimally invasive surgeries.

[0102] like Figures 14 to 27 As shown, in one embodiment of the present application, a support groove 513 is provided on one end of the guide channel 511 away from the mounting seat 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 extrusion section 522 enters the support groove 513 and presses against the bottom of the support groove 513, the extrusion section 522 cannot move due to the support of the bottom of the groove, so as to prevent the extrusion section 522 from moving too far and causing the guide tube 52 to not cooperate properly with the blocking part 20. That is, it is ensured that the guide tube 52 can cooperate with the blocking part 20 to ensure more effective suturing of the digestive tract tissue 400. It should be noted that in some embodiments, the guide tube 52 is sequentially connected to the through hole 11 of the mounting seat 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 Figure 25 to Figure 27 As shown, in one embodiment of the present application, a receiving groove 13 is provided on the mounting seat 10 , the receiving groove 13 is provided adjacent to the blocking portion 20 and is communicated with the through hole 11 , and the receiving groove 13 is configured to receive the digestive tract tissue 400 .

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

[0106] like Figures 1 to 4 , Fig.19As shown, in one embodiment of the present application, the endoscopic digestive tract treatment auxiliary component 100 further includes: a mounting tube 60. Specifically, the number of the mounting tube 60 can be one or more, wherein the multiple mounting tubes 60 are arranged in parallel.

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

[0108] The mounting tube 60 can protect the instrument and can be passed through by the endoscope, endoscope accessories and sutures. In addition, in some embodiments, the mounting tube 60 is relatively large, and its distal end is directly connected and fixed to the mounting seat 10 as a whole, and its distal end is located outside the human body, so that the surgical operator can hold its distal end by hand to manipulate the treatment auxiliary component.

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

[0110] Embodiment 1

[0111] like Figures 1 to 4 As shown, the endoscopic digestive tract treatment auxiliary component 100 includes: a mounting seat 10, a mounting tube 60 and a resisting portion 20.

[0112] The mounting seat 10 has two through holes 11 passing through it. The two through holes 11 are respectively used in conjunction with the endoscope 300 and the endoscope accessory 600 (clamping piece). The stapler 200 is located in the working channel of the endoscope 300.

[0113] The blocking portion 20 is disposed at an end of the mounting seat 10 and extends along the axial direction of the through hole 11 . The blocking portion 20 is configured to support the digestive tract tissue 400 .

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

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

[0116] After the endoscopic digestive tract treatment auxiliary part 100 enters the human body together with the endoscope 300, the clamp (endoscopic accessory 600) passes through the through hole 11 to pull the digestive tract tissue 400, so that the digestive tract tissue 400 is located on the resisting part 20, and then the endoscope 300 (ultrasound endoscope) passes through the mounting tube 60 to scan the part that needs puncture and suture. After excluding the organs and large blood vessels in and near the tissue, the suture device 200 is inserted into the working channel of the endoscope 300 to the front end, so that the harder suture needle of the suture device 200 is located at the non-bent part of the front end of the endoscope 300. Then, the digestive tract tissue 400 is clamped and squeezed by the cooperation of the bent part of the front end of the endoscope 300 and the resisting part 20, and then the suture device 200 is used to puncture and suture the digestive tract tissue 400.

[0117] Embodiment 2

[0118] like Figures 5 to 10 As shown, the endoscopic digestive tract treatment auxiliary component 100 includes: a mounting seat 10 and a resisting portion 20 .

[0119] The mounting seat 10 has two through holes 11 passing through it. The two through holes 11 are respectively used in conjunction with the endoscope 300 and the endoscope accessory 600 (clamping piece). The stapler 200 is located in the working channel of the endoscope 300.

[0120] The resisting portion 20 is disposed at the end of the mounting seat 10 and extends along the axial direction of the through hole 11. The resisting portion 20 is configured to support the digestive tract tissue 400. The resisting portion 20 can move relative to the mounting seat 10 through the cooperation of the first movable structure 12 and the second movable structure 21.

[0121] A reset member 30 is arranged between the mounting seat 10 and the resisting portion 20. Specifically, the reset member 30 is a spring. This structural mode is passively moved by the extrusion force, and there is no need to arrange a corresponding driving structure, so that the structure is simple.

[0122] The use process of the endoscopic digestive tract treatment auxiliary device 100 is basically the same as that of the first embodiment. The difference is that in some endoscopic minimally invasive surgeries, when the digestive tract tissue 400 being pulled is large, the digestive tract tissue 400 squeezes the resisting portion 20, so that the resisting portion 20 moves relative to the mounting seat 10 to increase the accommodation space and expand the puncture stroke, and then the suturing device 200 is used to suture the digestive tract tissue 400.

[0123] Embodiment 3

[0124] like Figures 11 to 13 As shown, the endoscopic digestive tract treatment auxiliary component 100 includes: a mounting seat 10, a first guide member 40 and a resisting portion 20.

[0125] The mounting seat 10 has two through holes 11 passing through it. The two through holes 11 are respectively used in conjunction with the endoscope 300 and the endoscope accessory 600 (clamping piece). The stapler 200 is located in the working channel of the endoscope 300.

[0126] The blocking portion 20 is disposed at an end of the mounting seat 10 and extends along the axial direction of the through hole 11 . The blocking portion 20 is configured to support the digestive tract tissue 400 .

[0127] The first guide member 40 includes a first connection seat 41 and an arcuate channel 42, the outlet of the arcuate channel 42 faces the stopper 20, the setting position of the arcuate channel 42 is opposite to the position of the stopper 20, the arcuate channel 42 is configured to guide the suture needle to the stopper 20, and the first connection seat 41 is configured to be connected to the endoscope 300. Different from the first and second embodiments, in this embodiment, it is not necessary to guide by bending the front end of the endoscope 300, but the suture needle of the suture device 200 is directed toward the stopper 20 for puncture suture by the first guide member 40. This structural method is simple, the required operating space is small, and the suture needle needs to have a certain elasticity to pass through the arcuate channel 42.

[0128] Embodiment 4

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

[0130] The mounting base 10 has two through holes 11 extending therethrough, one through hole 11 being fixedly sleeved with the front end of the endoscope 300, and the other through hole 11 being used in conjunction with the stapler 200. The endoscope accessory 600 (existing clamping piece) is located in the working channel of the endoscope 300 to clamp and pull the digestive tract tissue.

[0131] The blocking portion 20 is disposed at an end of the mounting seat 10 and extends along the axial direction of the through hole 11 . The blocking portion 20 is configured to support the digestive tract tissue 400 .

[0132] The guide tube 52 includes a deforming section 521 and an extruding section 522 connected in sequence, and the extruding section 522 passes through the guide channel 511 and protrudes out of the guide channel 511. The guide channel 511 is communicated with the through hole 11 of the mounting seat 10 and is also communicated with the mounting tube 60 for the stapler 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 extrusion section 522 , and is configured to control the extrusion section 522 to move toward the resisting portion 20 , so that the end of the extrusion section 522 cooperates with the resisting portion 20 to clamp the digestive tract tissue 400 .

[0134] After the endoscopic digestive tract treatment auxiliary part 100 enters the human body together with the endoscope 300, the suturing device 200 is inserted into the guide tube 52 so that its harder suture needle is located in the extrusion section of the guide tube 52 and avoids the deformation section. Then, the digestive tract tissue 400 is pulled to be located on the resistance part 20 through the clamping part (endoscopic accessory 600), and then the control cable 53 is dragged so that the control cable 53 controls the guide tube 52 to bend in the direction close to the resistance part 20, so that the extrusion section 522 presses the digestive tract tissue 400 against the resistance part 20, and the suture needle of the suturing device 200 is basically perpendicular to the tissue to be punctured for puncture and suturing.

[0135] Embodiment 5

[0136] like Fig.19 As shown, the endoscopic digestive tract treatment auxiliary component 100 includes: a mounting seat 10, a blocking portion 20, a second guide member 51, a mounting tube 60, a guide tube 52 and a control cable 53.

[0137] The difference from the fourth embodiment is that the distal end of a mounting tube 60 with a relatively large outer diameter is directly connected and fixed to the mounting seat 10 as a whole, and the distal end is located outside the human body. The surgical operator can hold the distal end by hand to manipulate the treatment auxiliary parts, and the endoscope 300 can pass through the mounting tube 60 and the through hole 11 of the mounting seat 10 and move forward and backward in the through hole. After the endoscope accessory 600 (the existing clamping part) located in the working channel of the endoscope 300 clamps the tissue, it pulls the clamped tissue into the through hole 11 of the mounting seat 10 and the mounting tube 60 together with the movable endoscope 300, with a longer pulling stroke to pull up enough tissue to be punctured and sutured. The remaining structure is the same as the fourth embodiment.

[0143] A reset member 30 is disposed between the mounting seat 10 and the blocking portion 20 . Specifically, the reset member 30 is a spring sheet.

[0144] The guide tube 52 includes a deformation section 521 and an extrusion section 522 which are connected in sequence. The extrusion section 522 passes through the guide channel 511 and protrudes out of the guide channel 511 .

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

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

[0147] Embodiment 7

[0148] like Figure 25 to Figure 27 As shown, the endoscopic digestive tract treatment auxiliary component 100 includes: a mounting seat 10, a blocking portion 20, a second guide member 51, a guide tube 52 and a control cable 53.

[0149] The mounting seat 10 has three through holes 11 passing through it, which are respectively used in conjunction with the endoscope accessory 600 (existing clamp), the endoscope 300 and the suture device 200. The endoscope accessory 600 cooperates (clamp) to pass through the mounting tube 60 and the through hole 11. The mounting seat 10 is provided with a receiving groove 13, which is arranged adjacent to the stopper 20 and is connected to the through hole 11 corresponding to the endoscope accessory 600 (clamp), and the receiving groove 13 is configured to accommodate the digestive tract tissue 400 to be sutured, so as to pull up enough tissue to be punctured and sutured.

[0150] The blocking portion 20 is disposed at an end of the mounting seat 10 and extends along the axial direction of the through hole 11 . The blocking portion 20 is configured to support the digestive tract tissue 400 .

[0151] The guide tube 52 includes a deformation section 521 and an extrusion section 522 which are connected in sequence. The extrusion section 522 passes through the guide channel 511 and protrudes out of the guide channel 511 .

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

[0153] like Figure 3 , Figure 4 ,to Fig.10 ,and Fig.13 As shown, the puncture stapler assembly provided by the embodiment of the second aspect of the present application includes: the above-mentioned endoscopic digestive tract treatment auxiliary component 100 and the stapler 200.

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

[0155] The puncture suturing device assembly has a simple structure and is easy to operate. The puncture and release suture pieces can be visualized under an existing endoscope 300 without the need for new equipment.

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

[0157] When the suture piece passes through the needle tube for suturing, due to the guiding effect of the needle tube itself, the suture piece can reach the position to be sutured more accurately, avoiding suture position deviation, and helping to accurately suture the digestive tract tissue 400, making the suture operation more accurate. In addition, when the operating space is limited, using the needle tube to assist in suturing allows the operator to better control the direction and depth of the suture. At the same time, the needle tube can also serve as a temporary support structure to help the operator stabilize the suture position, making the suture operation smoother.

[0158] like Figure 3 , Figure 4 , Fig.10 , Fig.13 and Fig.28 As shown, in one embodiment of the present application, the puncture stapler assembly further includes: a suturing piece.

[0159] The suture is disposed in the needle tube, and is configured to suture the digestive tract tissue 400 .

[0160] The suture member may be a suture needle or a suture post 500. Fig.29 As shown, the suture pile 500 includes at least two fixing piles 501 and a connecting line 502 connecting the two fixing piles 501. According to specific surgical needs, multiple fixing piles 501 connected in series on the connecting line 502 / suture line 502 can be set to achieve continuous puncture suturing.

[0161] If the needle suture piece can be a suture needle, after the needle tube passes through the digestive tract tissue 400, the suture piece with the suture thread 502 passes through the needle tube and punctures the digestive tract tissue 400 back and forth to suture the digestive tract tissue 400. Fig.30 and Fig.31 As shown, if the needle suture piece can be a suture post 500, after the needle tube passes through the digestive tract tissue 400, a fixed post 501 is pushed out of the needle tube, and then the needle tube is withdrawn. Since the fixed post 501 is limited by the human body component, the suture post 500 is gradually pulled out of the needle tube during the withdrawal process until the next fixed post 501 is out of the needle tube. The two fixed posts 501 are respectively located on both sides of the digestive tract tissue 400, and then the connection line 502 is pulled back to allow the two fixed posts 501 to suture the human digestive tract tissue 400 together.

[0162] like Fig.28 As shown, in one embodiment of the present application, the stapler 200 further includes a driving device 700 .

[0163] The driving device 700 is connected to the suture needle, and the driving device 700 is configured to drive the suture needle to move relative to the mounting seat 10. In a specific embodiment of the present application, the driving device 700 includes a threaded rod and a moving member, the moving member is screwed to the threaded rod, and the threaded rod can rotate relative to the moving member.
