Expansion type ureter mirror with bendable end

Abstract

The invention relates to a micro invasion endoscope of upper urinary tract disease diagnosis and treatment, which is a novel ureter endoscope formed by a terminal 2 of the bendable endoscope body, a rigid endoscope body 1 and operation keys 4 and 5 at the back of an operation handle 3. Most of the endoscope body is rigid structure, so the terminal of the endoscope is the same with the terminal of the traditional and soft ureter endoscope, which can be bended by 180 DEG C towards two opposite direction. The direction and angle of bending movement can be controlled by the operation key 4 at the back of the handle and operated conveniently. The invention has the advantages of the traditional ureter endoscope and soft ureter endoscope, is operated conveniently, no view and operation blind areas and the view is much clearer under the endoscope, which result in large improvement in the upper urinary tract disease diagnosis and treatment. While the operation key 5 can control relative sliding of the bendable endoscope body terminal and rigid endoscope body, so to reach the rigid structure of whole endoscope body during the endoscope entry process and protect the terminal of the soft endoscope body.

Description

technical field [0001] The invention belongs to the medical field, and relates to a minimally invasive endoscope used for diagnosis and treatment of upper urinary tract diseases.
