Guiding type urethral calculus extractor

Abstract

The invention relates to a guiding type urethral calculus extractor, and relates to the technical field of medical treatment. The guiding type urethral calculus extractor comprises a sleeve handle, a guide tube, an annular groove, an expansion air bag, a connecting tube, a crushing disc, an inflation tube, a miniature air pump and an air release valve. In an initial state, the outer diameter of the expansion air bag is equal to or smaller than that of the guide tube, and the miniature air pump inflates the expansion air bag during calculus extraction, and the inner wall of the urethra is supported and expanded through the expansion air bag. The calculus is taken out in a gradual guiding manner by expanding the air bag, so that the pain of a patient can be obviously relieved, and the damage to the urethral wall is avoided.

Description

technical field

[0001] The invention relates to the field of medical technology, in particular to a guided urethral stone remover. Background technique

[0002] The urethral calculi remover of the prior art lacks a protection mechanism for the inner wall of the urethra, and is easy to damage the urethra. For example, when removing a calculus, it is necessary to use claws to grab the calculus, and then remove the calculus by hard pulling after the calculus is obtained. Patients will feel a lot of pain during and after stone extraction, so this method needs to be improved. Contents of the invention

[0003] In order to solve the problems in the prior art, the present invention provides a guided urethral stone remover.

[0004] For realizing the above object, technical scheme of the present invention is:

[0005] A guided urethral calculi remover, comprising a sleeve handle and a guide tube for penetrating the urethra, the lower end of the outer wall surface of the guide tu...
