Enteroscopic sleeve with integrated structure

Abstract

The invention discloses an enteroscope cannula of an integral structure. The enteroscope cannula comprises a straight pipe fitting, one end of the straight pipe fitting is connected with an endoscope insertion opening, a gas injection port and a water injection port are formed in the pipe wall of the straight pipe fitting close to one end of the endoscope insertion opening, a capsule A is arranged on the outer wall of the straight pipe fitting far away from one end of the endoscope insertion opening, the gas injection port is communicated with an inner cavity of the capsule A through a micropore in the pipe wall of the straight pipe fitting and communicated with the inner cavity of the straight pipe fitting, the other end of the straight pipe fitting is connected with a corrugated pipe, the other end of the corrugated pipe is connected with a capsule B, and the endoscope insertion opening, the straight pipe fitting, the corrugated pipe, the capsule A and the capsule B are of the integral structure. When the enteroscope cannula of the integral structure is used, the corrugated pipe is telescopic, and the change of the distance between the two capsules is conveniently achieved. When matched with an enteroscope in use, the enteroscope cannula is convenient to operate, safe and reliable, working difficulties of medical technicians are greatly reduced, and illness suffering of patients is reduced to a great extent.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an enteroscope sleeve with an integrated structure. Background technique [0002] Medical endoscopes have been widely used for medical examination, surgical treatment, etc. Endoscopic medicine is an interdisciplinary subject of minimally invasive medicine and imaging medicine. It is applied to: digestion, respiration, chest, abdomen, urology , Reproductive and other departments. [0003] Medical endoscopes are basically divided into two categories: rigid tube scopes and flexible tube scopes. The small intestine of the human body is about 5-7 meters. Due to the characteristics of the anatomical structure of the small intestine, an overtube is usually used during the small intestine examination to facilitate a more comprehensive inspection of the patient's small intestine. [0004] At present, there are two methods of enteroscopic examination in clinical use: single-balloon and...
