Digestive tract endoscope bending and fixing device

Abstract

The invention belongs to the technical field of endoscopes, and discloses a digestive tract endoscope bending and fixing device. The digestive tract endoscope bending and fixing device comprises an outer sleeve arranged on an endoscope tube in a sleeving mode; the outer sleeve comprises a plurality of circular rings arranged on the endoscope tube in a sleeving mode; the circular rings are connected in series through inflation tubes sequentially penetrating through the circular rings; and the inflation tube between every two circular rings is of an inflation expansion telescopic structure. According to the digestive tract endoscope bending and fixing device, when an endoscope tube needs to be bent, gas is introduced into the inflation tube on the opposite side of the bent side, the inflation expansion telescopic structure extends, the distance between the circular rings on the opposite side of the bent side is increased, the distance between the circular rings on the opposite side of the bent side is not changed, and therefore the outer sleeve is bent; and the endoscope tube in the outer sleeve is driven to be synchronously bent, and the endoscope body can be bent to a greater extent through the bending of the original bending part. The device is further provided with air cushions in different directions, so that the lifting and fixing effects can be achieved, and endoscopic examination and treatment are facilitated.

Description

technical field [0001] The invention belongs to the technical field of endoscopes, in particular to a bending and fixing device for digestive tract endoscopes. Background technique [0002] Gastrointestinal endoscopy is a common medical examination and treatment method. At present, the guidelines of various countries have taken gastrointestinal endoscopy as an important part of physical examination. The treatment of choice for the disease. Although the current clinical technology for the use of gastrointestinal endoscopy is very mature, there are still some difficult parts (such as gastric angle, gastric fundus, duodenum, colon, etc.), especially when endoscopic resection is required, there are still some difficulties. Greater difficulty. There are two main reasons: [0003] 1. "Out of reach", the endoscope cannot approach the lesion well: [0004] The front end of the medical endoscope contains a curved part, which can change the direction and angle of the probe through...

AI Technical Summary

Problems solved by technology

When the wire rope is pulled to make the snake bone bend, the adjacent joint units will interfere with each other, and the length of the front end bending part is often limited (for example, about 10 cm for a gastroenteroscope), so in a relatively large internal cavity (such as the stomach) lumen, especially the gastric angle, fundus region), or where the endoscope has been bent at a large angle (such as in the colon), the endoscope is usually limited in angle and cannot get close to the lesion well, so it cannot be observed freely and treatment, it is very easy to cause blind spots in endoscopic examination, affect the accuracy of examination results, and increase the difficulty of endoscopic treatment

[0005] 2. "Unable to fix", the endoscope cannot be stabilized in the lesion area, and endoscope slippage is prone to occur:

Therefore, the endoscopic treatment of the area where the endoscope cannot be stably fixed is a difficult point in the field of endoscopic treatment, and it is also a high-risk treatment area.
