Description

Endoscope assistor

Technical Field

The invention relates to the technical field of medical instruments, in particular to an endoscope assistor.

Background

Colonoscopes are used for endoscopic examination of the colon and distal portions of the small intestine, and flexible sigmoidoscopes are used for examination of the rectum and lower part of the intestine. Each endoscopic procedure may provide a visual diagnosis, such as an ulcer, polyp, and permit biopsy or resection of a suspicious lesion. The current colonoscopy procedure has two problems: 1. the lining of the colon is a pleated structure that can impede the ability of medical personnel to view the entire surface of the mucosa as the distal end of the endoscope passes along the lumen of the colon, especially during extubation to detect lesions hidden within the pleats. 2. Maintaining the position of the tip can be difficult from the detection of tissue damage to the completion of the procedure, and slippage of the tip often occurs when the colonoscope is withdrawn, thereby causing the health care provider to lose the desired position and, if the tip position is lost, repositioning of the tissue damage. In order to create a good medical environment, the invention provides an endoscope auxiliary piece which can simultaneously solve the two problems.
