Problems solved by technology

In order to solve similar problems, the dental floss traction method is currently used clinically, but the dental floss traction method has many disadvantages: the lesion can only be tracted on one side of the upper gastrointestinal tract side or the anal side of the lower digestive tract; when using the traction rope, it will block the line of sight and interfere The field of view under the endoscope makes the operation of the endoscope more inconvenient; due to the friction between the traction rope and the endoscope, the medical staff cannot control the traction force well, which may easily lead to bleeding in the cardia and other places

Embodiment 1

[0029] In this embodiment, the endoscopic cuff index is used in endoscopic submucosal dissection, and the following combination of appendix Figures 2 to 3 The specific application of the present invention in endoscopic submucosal dissection is described:

[0030] The surface of the human intestine is the mucosal layer 11 , and the mucosal layer 11 is next to the submucosa 12 and the muscularis propria 13 . During the operation, the doctor first understands the size and shape of the lesion 1, and marks 21 on the edge of the lesion 1 if necessary. Then, a separation solution 22 for lifting the lesion 1 is injected into the submucosa 12 . The separation solution 22 can separate the lesion 1 from the muscularis propria 13 , which is conducive to the complete excision of the lesion 1 without damaging the muscularis propria 13 . ,like image 3 (a) is the surgical site that has undergone the above treatment. Among them, the separation liquid 22 can use physiological saline, glyce...

Embodiment 2

[0035] In this embodiment, the endoscopic lasso is used in the endoscopic retrograde cholangiopancreatography, in combination with the following Figure 4 (a) to (b) describe the specific application of the present invention in endoscopic retrograde cholangiopancreatography:

[0036] In the process of endoscopic retrograde cholangiopancreatography, the duodenoscope needs to be inserted into the descending part of the duodenum 41, and after finding the duodenal papilla 42, a contrast catheter is inserted into the biopsy tube to the opening of the papilla Section, X-ray after injection of contrast agent to show the pancreaticobiliary duct. However, in the course of clinical surgery, such as Figure 4 As shown in (a), since the duodenal papilla 42 is often blocked by folds in the intestine, it is difficult to find the papilla and inject a contrast medium into the opening of the papilla.

[0037] In this embodiment, the A end of the traction ring 31 is fixed at the fold that cov...

Abstract

The invention discloses a lasso traction method under an endoscope, which comprises the following steps: S1, fixing one end of the traction ring to the tissue to be retracted through a fixing clip to form end A; S2, using another fixing clip to fix the end of the traction ring The other end is fixed at end B away from end A; S3, retract the traction ring, end B is fixed, and end A moves closer to end B under the action of the traction ring; S4, repeat step S3 until the tissue is completely opened. The present invention can adjust the direction in which the tissue needs to be retracted according to the needs of the operation, and can be more flexibly applied to different operations and different operation situations; when traction is required, the traction is performed without constantly acting and pulling the traction ring, reducing the number of endoscopes. The occluded field of view will not hinder the surgical operation of the medical staff; and the traction ring can be gradually tightened according to the progress of the operation, which can better grasp the traction force, avoid unnecessary traction on normal tissues, and reduce the pain during the operation. Bleeding and other injuries.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an endoscopic noose. Background technique [0002] Endoscopic submucosal dissection is a new treatment method that has appeared in recent years, and it is also a technology with good clinical application prospects. pain and removal of organs. [0003] During endoscopic submucosal dissection, some lesions are often encountered and require the use of traction to pull the lesioned mucosa away to obtain a better view, so that the endoscope can enter the lesion more smoothly to separate the tissue. In order to solve similar problems, the dental flossing method is currently used clinically, but the dental flossing method has many disadvantages: the lesions can only be pulled on one of the upper gastrointestinal orifice side or the lower gastrointestinal anal side; when using the traction rope, it will block the sight and interfere The field of view under the endoscope makes t...
