AI Technical Summary

Technical Problem

In current endoscopic examinations, intestinal folds hinder complete visualization of the mucosal surface, especially when detecting hidden precancerous and malignant lesions. Furthermore, the large diameter of traditional cannulas causes patient discomfort when passing through sharp turns and sphincter muscles.

Method used

A sleeve comprising a tubular member and multiple pivotable protruding elements is designed. The protruding elements interact with the contact area via brakes, restricting their distal movement, providing greater opening force to unfold the folds, and reducing contact with the distal edge upon retraction, thereby enhancing visibility and control.

Benefits of technology

It improves the visualization of endoscopic examinations, reduces patient discomfort during cannula withdrawal, and enhances the visualization of intestinal folds, especially when detecting hidden lesions.

Abstract

A sheath (1) for a shaft of a medical scoping device comprises a tubular member (2) arranged for application over a distal tip of a medical scoping device. The sheath (1) comprises a plurality of protruding elements (3) circumferentially spaced around the tubular member (2), each protruding element having a base portion (13) and an arm portion (14). The protruding elements are pivotably mounted on the tubular member about a pivot axis. The base portion (13) comprises a detent (20) and the tubular member comprises a contact area, such as a protrusion (23), positioned such that a pivoting movement of the protruding elements for moving the arm portion in a distal direction enables the detent (20) to hit against the contact area (23).
