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.

[0048] like Figures 1 to 10 As shown, an embodiment of the first aspect of the present application provides an endoscopic digestive tract folding device 100 for use with an endoscope 300 and a stapler 200, comprising: a mounting tube 10, a deformation tube 20, a clamping portion 30 and a control cable 40.

[0049] An observation window 11 is provided at one end of the mounting tube 10 . The observation window 11 is located on the tube wall of the mounting tube 10 . The mounting tube 10 has a channel 12 running through it. The channel 12 is configured for the endoscope 300 and the stapler 200 to pass through.

[0050] One end of the deformable tube 20 is disposed at the end of one end of the mounting tube 10 , and the deformable tube 20 is configured to be bendable and deformable.

[0051] The clamping portion 30 is disposed at the other end of the deformation tube 20 .

[0052] The control cable 40 is connected to the clamping part 30, and the control cable 40 is configured to control the clamping part 30 to move toward the installation tube 10 so that the clamping part 30 and the installation tube 10 cooperate to squeeze the digestive tract tissue 400. For easy operation, an operating handle can be provided at the end of the control cable 40.

[0053] Taking the esophageal gastric fundus and cardia as an example, the endoscopic digestive tract folding device 100 provided in the present application is operated as follows:

[0054] 1. Put the endoscopic digestive tract folding device 100 on the endoscope 300. Under the guidance of the endoscope 300, the operator inserts the endoscopic digestive tract folding device into the esophagus and stomach cavity. The observation window 11 of the mounting tube 10 is located at the esophageal cardia, and the clamping part 30 is located at the gastric fundus.

[0055] 2. The operator inserts the field of view lens of the endoscope 300 (for example, an ultrasonic endoscope) into the mounting tube 10, and places the field of view lens and the working channel of the endoscope 300 at the observation window 11. The field of view lens of the endoscope 300 can scan the digestive tract tissue 400 through the observation window 11 to observe the situation outside the digestive tract lumen.

[0056] 3. The operator operates the control cable to make the clamping part 30 clamp and squeeze the stomach fundus, so that the stomach fundus to be punctured fits close to the esophagus. Specifically, the operator drags the control cable 40, and the control cable 40 controls the clamping part 30 to move in the direction of approaching the installation tube 10, so that the clamping part 30 brings the stomach fundus closer to the esophagus, and finally the stomach fundus is pressed against the esophagus through the cooperation of the clamping part 30 and the installation tube 10. In addition, if Figures 6 to 8 As shown, if a parallel channel is set inside, outside or in the wall of the mounting tube 10, the existing auxiliary instruments of the endoscope (such as endoscopic forceps) can pass through the parallel channel to grasp the gastric fundus and cardia tissue, so as to pull the gastric fundus and cardia tissue between the mounting tube 10 and the clamping part 30, so as to improve the effectiveness and safety of the operation.

[0057] 4. The operator inserts the stapler 200 into the working channel of the endoscope 300 to the observation window 11, and then punctures the puncture site and anchors the suture.

[0058] The endoscopic digestive tract folding device 100 provided in the present application can push away the organs, blood vessels and tissues on the operation path after entering the human body, and form an independent operation channel 12 in the human body, thereby avoiding the situation where the suturing device 200 damages the organs and large blood vessels at the puncture site during the process of entering the human body or puncturing and suturing, that is, greatly improving the safety of the puncture and suturing process. In addition, the fundus of the stomach is relatively free, and it is not easy to penetrate during the puncture process from the esophagus to the fundus of the stomach. Therefore, the endoscopic digestive tract folding device 100 is used for squeezing and supporting, so that the puncture is completed more safely and effectively.

[0059] In addition, the endoscopic digestive tract folding device 100 has a simple structure, and there is no complicated connection structure between the components, which makes the overall structure of the product more compact and stable. At the same time, the endoscopic digestive tract folding device 100 is simple to operate, making it easier for the operator to understand its working principle and operation method. Even if it is easy for the operator to get started, the operator can complete the operation more quickly and it is less likely for the operator to make operating errors.

[0060] like Figures 1 to 5 As shown, in one embodiment of the present application, the deformation tube 20 is a spring tube. In addition, the mounting tube 10 can also be a spring tube.

[0061] The spring tube has excellent fatigue resistance and can withstand repeated bending without damage. This allows the product to maintain good performance after multiple inspections, reducing the frequency of repairs and replacements due to pipeline damage.

[0062] In another embodiment of the present application, the deformation tube 20 includes at least one connecting ring 21 .

[0063] When the deformation tube 20 is bent, the stress is dispersed at the hinged part of the connecting ring 21, avoiding stress concentration and reducing the risk of local fatigue damage, thereby improving the durability of the deformation tube 20. In addition, the connecting ring 21 can maintain good shape stability after bending and is not prone to shaking or deformation.

[0064] like Figure 4 and Figure 5 As shown, in one embodiment of the present application, a through hole 31 is provided on the clamping portion 30 , and the through hole 31 is configured to allow a puncture needle of the stapler 200 to pass through.

[0065] The through hole 31 provides a puncture space for the puncture needle so that the puncture needle can puncture the digestive tract tissue 400 more effectively, that is, it is convenient for the puncture needle to puncture the digestive tract tissue 400, so as to improve the suturing effect of the product on the digestive tract tissue 400.

[0066] In one embodiment of the present application, a receiving groove 32 is provided on the clamping portion 30 , and the receiving groove 32 is configured to receive the digestive tract tissue 400 .

[0067] The arrangement of the accommodating groove 32 enables the clamping portion 30 to accommodate more stomach wall.

[0068] like Fig. 9 and Fig.10 As shown, in a specific embodiment of the present application, the deformation tube 20 includes a plurality of hinged connection rings 21 .

[0069] The deformation tube 20 articulated with multiple connection rings 21 can achieve more complex and multi-dimensional bending, and can better adapt to various irregular-shaped spaces and complex path requirements. In addition, the articulated structure of the connection ring 21 can more accurately control the bending angle and shape of the deformation tube 20. By adjusting the angle of each connection ring 21, the degree of bending can be finely adjusted to meet the requirements for bending accuracy in different scenarios.

[0070] In one embodiment of the present application, when the deformation tube 20 is a spring tube, the mounting tube 10, the deformation tube 20 and the clamping portion 30 are an integrally formed one-piece structure.

[0071] The above structure ensures the connection strength between the installation tube 10, the deformation tube 20 and the clamping part 30, thereby ensuring the overall mechanical strength of the product, so as to ensure the reliability of the product.

[0072] like Figures 1 to 10 As shown, in one embodiment of the present application, the endoscopic digestive tract folding device 100 further includes: a guiding structure 50.

[0073] The guide structure 50 is disposed at one end of the mounting tube 10 , and the control cable 40 is connected to the clamping portion 30 after passing around the guide structure 50 .

[0074] The guide structure 50 provides stable support and restraint for the control cable 40 , so that the control cable 40 controls the deformation tube 20 to remain relatively stable during the bending process, thereby preventing unnecessary shaking or deviation during operation.

[0075] In addition, the guide structure 50 can make the control cable 40 move within a specified path, avoiding unnecessary friction and collision between the control cable 40 and other components or pipe walls, thereby effectively reducing the wear rate of the control cable 40, extending its service life, reducing the risk of product failure caused by damage to the control cable 40, and improving the reliability of the entire product.

[0076] like Figures 1 to 10 As shown, in one embodiment of the present application, the guide structure 50 is a fixed pulley 51 , and the fixed pulley 51 is rotatably mounted on the mounting tube 10 .

[0077] The above structure enables rolling friction between the control cable 40 and the guide structure 50, thereby greatly reducing the friction between the control cable 40 and the guide structure 50, reducing the wear of the control cable 40 itself, extending its service life, and at the same time reducing the additional power required to overcome the friction.

[0078] In addition, since the endoscopic digestive tract folding device 100 is small in size and the available space is limited, the fixed pulley 51 can be flexibly installed in different positions according to the actual equipment layout and operation requirements to achieve the steering of the control cable 40, which makes the design and layout of the entire product more flexible.

[0079] In one embodiment of the present application, the endoscopic digestive tract folding device further includes: a control pipe.

[0080] The control pipe is connected with the installation pipe, and one end of the control cable passes through the control pipe and is connected with the clamping part.

[0081] The setting of the control pipeline can ensure that the control cable and other instruments are located in different channels, so that there will be no mutual interference between the control cable and other instruments, and the movement of the control cable in the tube is smoother, thus ensuring the accuracy of the operation and greatly improving the efficiency and precision of the operation.

[0082] like Figures 1 to 10 As shown, in another embodiment of the present application, one end of the control cable 40 passes through the channel 12 of the mounting tube 10 and is connected to the clamping portion 30 .

[0083] The above structure allows the control cable 40 to share a channel 12 with other devices. On the one hand, it is conducive to the integration of different devices and makes the cooperation between the various devices closer. On the other hand, it can make the overall structure of the product more compact and easy to operate.

[0084] like Figures 1 to 10 As shown, in one embodiment of the present application, the number of the control cables 40 is two, and the two control cables 40 are connected to two connecting parts symmetrically arranged on the clamping part 30 .

[0085] The above structure enables the control cable 40 to achieve precise operation of the connecting part. The two symmetrically arranged control cables 40 can apply tension to the clamping part 30 from different directions, so that the position, angle and movement direction of the clamping part 30 can be precisely controlled like operating a robotic arm, thereby improving the accuracy and safety of product operation.

[0086] In addition, the symmetrically arranged control rope 40 can balance the force exerted on the connecting part, preventing the clamping part 30 from shaking due to the pulling force in a single direction, thereby ensuring that the clamping part 30 remains stable, preventing operational errors or damage to surrounding tissues due to shaking, and improving the accuracy and safety of product operation.

[0087] In one embodiment of the present application, a (such as Figures 1 to 5 as shown) or multiple (as Figures 6 to 8 As shown, a channel 12 is parallel to the channel 12 for the endoscope accessories to pass through.

[0088] Since the multiple channels 12 are relatively independent, different instruments can enter different channels 12 without mutual interference, making the instruments move more smoothly in the tube, so that they can be positioned more accurately at the target position, while ensuring the accuracy of the operation and greatly improving the efficiency and safety of the operation. Figure 8 As shown, during the implementation process, the existing endoscopic forceps (endoscopic accessories) are inserted through the parallel channel 12 to clamp and pull the gastrointestinal wall tissue (digestive tract tissue 400), making it more effective to implement puncture. At the same time, the site to be punctured can be kept away from the organs and blood vessels outside the cavity, thereby improving the safety of the operation.

[0089] like Figure 5 or Figure 8 As shown, the embodiment of the second aspect of the present application provides a puncture stapler assembly for use with an endoscope 300, including: an endoscopic digestive tract folding device 100 and a stapler 200.

[0090] The puncture needle of the stapler 200 is inserted into the working channel of the endoscope 300 and extends to the end of the mounting tube 10 . The stapler 200 is configured to fix the suture on the digestive tract tissue 400 .

[0091] The puncture suture assembly provided by the present application implements compression of the digestive tract wall before puncture, especially in the folding of the gastric fundus and cardia, so that the gastric fundus and esophagus are brought closer, so as to shorten the puncture stroke and push away the organs and blood vessels on the puncture path. At the same time, the relatively mobile and free gastric fundus is fixed, which improves the safety of puncture and completes the puncture more efficiently. The device can use the existing ultrasonic endoscope to visualize the puncture release suture, without the need for new equipment. Under visualization, the situation on the puncture path can be clearly observed, which greatly improves safety and accuracy. In addition, the structure of the puncture suture assembly is simple, and at the same time, it allows the operator to complete the operation more quickly and is not prone to operating errors.

[0092] In one embodiment of the present application, the puncture needle is a needle tube, and the needle tube is configured to guide the suture through the digestive tract tissue 400 .

[0093] The suture piece is constrained inside the needle tube and will not swing or bend at will. This method can effectively prevent the puncture needle from excessively penetrating or tearing the tissue, thereby reducing additional damage to the gastric tissue during surgery. 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 part that needs to be sutured more accurately, avoiding deviation in the suture position, 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 a 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 site, making the suture operation smoother.

[0094] In one embodiment of the present application, the puncture stapler assembly further includes: a suturing piece.

[0095] The suture is disposed in the needle tube, and is configured to suture the digestive tract tissue 400 .

[0096] The suture piece can be a puncture needle or a suture post. Fig.11 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 with the connecting line / suture 502 can be provided to achieve continuous puncture suturing.

[0097] If the needle suture piece can be a puncture needle, after the needle tube passes through the digestive tract tissue 400, the suture piece with the suture thread passes through the needle tube and punctures the digestive tract tissue 400 back and forth to suture the digestive tract tissue 400. Fig.12 and Fig.13 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 and the digestive tract tissue 400 are limited, 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.
