Endoscope sleeve

Abstract

The invention belongs to the field of endoscopy devices and particularly relates to an endoscope sleeve. The endoscope sleeve is arranged at the front end of an endoscope, and a first sleeve and a second sleeve are connected through a plurality of convex elastic portions distributed peripherally. The endoscope sleeve further comprises secondary support portions, one end of each secondary support portion is connected with the lower middle end of the corresponding convex elastic portion, and the other end of each secondary support portion is connected with the second sleeve. The endoscope sleeveis convenient and simple in mounting, large in open radius and wide in view field; in addition, due to small feeding radius, serious pains of patients are avoided.

Description

technical field [0001] The invention belongs to the field of endoscope inspection devices, in particular to an endoscope sleeve. Background technique [0002] In endoscopy or surgery, flexible instruments are used to view body cavities, such as the gastrointestinal tract and many other body cavities. Due to the length and curl of the intestine, especially the folded structure, there are situations that cannot be detected during inspection, and these folds hinder the diagnosis of whether there are lesions or malignant lesions in the folds of the intestine. In order to overcome the problems faced by microscopic examination, At present, the existing technology mainly adopts the cover for medical endoscopic instruments with the notification number CN102905608 to prop up the fold structure through the protruding elements, but in practical application, it is found that the protruding elements have limited support for the folds and cannot expand the inner well.

Problems solved by technology

Due to the length and curl of the intestine, especially the folded structure, there are situations that cannot be detected during inspection, and these folds hinder the diagnosis of whether there are lesions or malignant lesions in the folds of the intestine. In order to overcome the problems faced by microscopic examination, At present, the existing technology mainly adopts the cover for medical endoscopic instruments with the notification number CN102905608 to prop up the fold structure through the protruding elements, but in practical application, it is found that the protruding elements have limited support for the folds and cannot expand the inner well. looking glass field of view

In addition, there is also a kind of endoscope end cap that adopts the notification number CN108261174 and also adopts protruding elements. Although the end cap is a smooth, angular-like cylindrical structure, it solves the problem when entering, but it takes a lot of time to withdraw the mirror. Only a large force can make the protruding element stretch, and in the area with a large intestinal diameter, there will be one side that cannot touch the intestinal wall, and the hidden area on the intestinal tract cannot be inspected, which reduces the inspection effect of the endoscope
