[0027] The length of the first balloon 12 is adjusted by inflation and deflation, the top of the first balloon 12 has two positions of exceeding the front end of the front end cap 11 and not exceeding the front end of the front end cap 11, and the top of the first balloon 12 exceeds the front end of the front end cap 11 after inflation, the first balloon 12 can be used for pressing and hemostasis of a lesion wound, the distance between the front end cap 11 and the lesion wound is adjusted by extrusion to adjust the operation space, which helps to expand the operation field, and the expanded first balloon 12 can also support the lesion operation field.

[0028] The pressing force of the first balloon 12 on the wound after inflation is adjusted, if there is a possible bleeding point at the position, the bleeding will stop when the pressing force is enough, and if the pressing force is reduced, the bleeding will be observed, through the process, the bleeding position can be effectively judged to effectively stop bleeding.

[0029] After the first balloon 12 is deflated, the top of the first balloon 12 retreats to the position of not exceeding the front end of the front end cap 11, which does not affect the existing functions of the front end cap 11 and avoids blocking the operation field under the endoscope 10.

[0030] In some embodiments, the first balloon 12 is arranged with a compression spring 14, the compression spring 14 is arranged coaxially with the front end cap 11, and the compression spring 14 is used for supporting the first balloon 12. During the inflation and deflation process of the first balloon 12, the compression spring 14 is synchronously expanded and contracted with the first balloon 12 to avoid the position deviation of the first balloon 12. The compression spring 14 is arranged in the first balloon 12, the compression spring 14 is fixedly installed with the inner wall of the first balloon 12, the compression spring 14 is contracted after the first balloon 12 is deflated, the first balloon 12 is retreated, and thus the side membrane of the first balloon 12 avoids blocking the operation field under the endoscope 10.

[0031] In some embodiments, the lower side of the front cap 11 is provided with a sleeve part 15 sleeved outside the endoscope 10, the side wall of the sleeve part 15 is formed with a receiving structure 16 through which the first air tube 13 passes, the receiving structure 16 is formed with a groove or a channel, and the receiving structure 16 and the groove or the channel are arranged along the length direction of the sleeve part 15, so as to avoid the line of the first air tube 13 from being entangled and affecting the operation.

[0032] The present application relates to an auxiliary instrument applied to endoscopic surgery, which comprises a front cap 11, a first balloon 12 with variable length, and a second balloon 17 with variable thickness, which is the structure of the second embodiment of the auxiliary instrument. The front cap 11 is installed at the front end of the endoscope 10, the first balloon 12 is sleeved outside the outer wall of the front cap 11, and the first balloon 12 is provided with a first air tube 13 for inflation and deflation. The second balloon 17 is sleeved outside the endoscope 10, and the second balloon 17 is provided with a second air tube 18 for inflation and deflation.

[0033] The length of the first balloon 12 is adjusted by inflation and deflation, the top of the first balloon 12 has two positions of exceeding the front end of the front cap 11 and not exceeding the front end of the front cap 11, and the top of the first balloon 12 exceeds the front end of the front cap 11 after inflation, so that the first balloon 12 can be used to compress and stop bleeding of a lesion wound, the distance between the front cap 11 and the lesion wound is adjusted by extrusion to adjust the operation space, which helps to expand the operation field, and the inflated first balloon 12 can also support the lesion operation field.

[0034] The force of the first balloon 12 to compress the wound after inflation is adjusted, if there is a possible bleeding point at the position, the bleeding will stop when the compression force is sufficient. If the compression force is reduced, bleeding will be observed, through this process, we can effectively determine the bleeding position, so as to effectively stop bleeding.

[0035] After the first balloon 12 is deflated, the top of the first balloon 12 retreats to the position of not exceeding the front end of the front cap 11, which does not affect the existing functions of the front cap 11 and avoids blocking the operation field under the endoscope 10. After the second balloon 17 is inflated, the outer wall is expanded, the tissue at the lesion is supported to expand the operation field, bleeding can be stopped by compression, the mucosal tissue around the scope is extruded to fix the endoscope 10, and the endoscope 10 is prevented from slipping due to intestinal peristalsis.

[0036] In some embodiments, the first balloon 12 is arranged with a compression spring 14 arranged coaxially with the front end cap 11, the compression spring 14 being used to support the first balloon 12. During inflation and deflation of the first balloon 12, the compression spring 14 is synchronously expanded and contracted with the first balloon 12, avoiding displacement of the first balloon 12. The compression spring 14 is arranged in the first balloon 12, and is fixedly installed on the inner wall of the first balloon 12. After deflation of the first balloon 12, the compression spring 14 is contracted, driving the first balloon 12 to retreat, thereby avoiding blocking of the surgical field under the endoscope 10 by the side membrane of the first balloon 12.

[0037] In some embodiments, the lower side of the front end cap 11 is arranged with a sleeve portion 15 sleeved outside the endoscope 10, and the second balloon 17 is sleeved outside the sleeve portion 15. The side wall of the sleeve portion 15 is formed with a receiving structure 16 through which the first gas tube 13 and the second gas tube 18 pass, and the receiving structure 16 is formed with a groove or a channel, and the receiving structure 16 and the groove or the channel are arranged along the length direction of the sleeve portion 15, avoiding entanglement of the lines of the first gas tube 13 and the second gas tube 18 and affecting operation.

[0038] The front end of the receiving structure 16 has an inlet through which the first gas tube 13 is inserted, and the receiving structure 16 is formed with an inlet through which the second gas tube 18 is inserted. The outer wall of the sleeve portion 15 is formed with an annular groove, and the annular groove cuts off the receiving structure 16 to form the inlet through which the second gas tube 18 is inserted.

[0039] In some embodiments, the number of the second balloon 17 is at least one, and if the number of the second balloon 17 is designed to be two or more, each second balloon 17 is installed at any position outside the endoscope 10 or the sleeve portion 15. For example, each second balloon 17 is sequentially sleeved on the sleeve portion 15, and when performing minimally invasive surgery in the stomach cavity, the second balloon 17 located in the esophageal segment can be inflated to effectively compress the esophageal mucosal tissue, thereby fixing the scope body.

[0040] In some embodiments, if the number of the second balloon 17 is designed to be two or more, the corresponding receiving structure 16 should be designed to have an inlet corresponding to the number of the second balloon 17 through which the second gas tube 18 is inserted.

[0041] The following describes the use method of the second auxiliary instrument embodiment. The endoscope 10 is inserted from the end of the sleeve portion 15, and the front end of the endoscope 10 is fixed in the front end cap 11. The auxiliary instrument is inserted into the digestive tract lumen together with the endoscope 10 to assist in minimally invasive endoscopic surgery. When the first balloon 12 is not inflated, the first balloon 12 does not affect the operation of the front end cap 11, and the operation method is the same as that of conventional endoscopic surgery.

[0042] The auxiliary instrument can play a role when the following operations are encountered: first, when bleeding, the first balloon 12 is inflated, the first balloon 12 presses the wound, and the bleeding position is checked one by one. Second, when the surgical field is poor and the operation space is limited, the first balloon 12 and / or the second balloon 17 can be inflated to support the tissue and expand the surgical field. Third, to avoid the endoscope 10 from slipping due to the peristalsis of the gastrointestinal tract, the second balloon 17 can be inflated to press the inner wall of the gastrointestinal tract, thereby fixing the scope and avoiding slipping.

[0043] The method for checking the bleeding position is as follows: when the first balloon 12 presses the wound, the pressing force of the first balloon 12 on the wound is adjusted. If there is a possible bleeding point at the position, the bleeding will stop when the pressing force is larger. Further, the bleeding will be observed by appropriately reducing the pressing force. Through the change of non-bleeding and bleeding in this process, the bleeding position can be effectively determined.

[0044] The embodiments of the application are described in detail above with reference to the drawings, but the application is not limited to the above-described embodiments. Various changes can be made within the knowledge of those skilled in the art in the technical field without departing from the purpose of the application.
