Problems solved by technology

However, this type of enteroscope is still a forward-stacking structure. During its operation, when the mirror body reaches a certain depth of the small intestine, the invaginated small intestine accumulates at the front end of the cannula, which will cause the balloon at the front end of the cannula to be unable to continue. function to make further lensing

Embodiment 1

[0015] The rear stacked enteroscope sleeve is composed of a sleeve body 1, a front sleeve air bag 2, a rear stack air bag 3, a water injection tube 4, an inflation tube 5 and a rear stack air bag inflation tube 6.

[0016] The front sleeve airbag 2 and the sleeve rear stack airbag 3 are respectively fixed on the front end of the sleeve body 1 and the middle part of the sleeve body 1 . The inflation pipe 5, the water injection pipe 4 and the rear stack air bag inflation pipe 6 are all fixed on the rear end of the sleeve pipe body 1. The inflatable tube 5 and the rear stack airbag inflation tube 6 communicate with the front casing airbag 2 and the casing rear stack airbag 3 through the airways 7 and 8 respectively; the water injection pipe 4 communicates with the inner cavity of the casing body 1 .

[0017] During use, firstly, the sleeve sleeve of the enteroscope of the present invention is sleeved on the endoscope. During use, when the endoscope enters the far end, the airbag...

Abstract

The invention discloses a back-folded type enteroscopy bushing, belonging to a field of medical machinery. The enteroscopy bushing in the prior art includes a bushing body provided with an injection tube and a charging tube. The front end of the bushing body is provided with an air sac for a front bushing and the air sac for the front bushing is communicated with the charging tube. The structure is a front-folded type enteroscopy bushing. The back-folded type enteroscopy bushing of the invention is characterized in that the middle part of the bushing body is provided with a back-folded air sac for the bushing used for leading a small intestine wall to move backwards. Compared with the prior art, the back-folded type enteroscopy bushing of the invention has the advantages of convenient use and being able to lead an endoscope to reach a deeper part of the small intestine in a shorter time, etc. The invention can be widely applied in various diseases of the small intestine and has an excellent popularization and application value.

Description

technical field [0001] The invention relates to a medical device, in particular to a rear-folding enteroscope casing. Background technique [0002] Fujinon double-balloon electronic enteroscope is one of the most commonly used tools for small bowel inspection in the prior art. It uses the cannula and the two balloons at the front end of the endoscope body to fix the intestinal canal relative to each other, and intussulates the small intestine on the cannula, so that the enteroscope can enter the deep part of the small intestine that the scope body could not enter before. , Improve the diagnostic rate of diseases in the upper middle part of the small intestine and the lower part of the ileum. However, this type of enteroscope is still a forward-stacking structure. During its operation, when the mirror body reaches a certain depth of the small intestine, the invaginated small intestine accumulates at the front end of the cannula, which will cause the balloon at the front end ...
