Flexible lens of electronic bronchoscope

Abstract

The invention belongs to the field of medical instruments and discloses a flexible lens of an electronic bronchoscope, which comprises a soft lens body, the soft lens body comprises a linear part and a bent part arranged at one end of the linear part, a pull wire is arranged in the bent part, one end of the pull wire is fixed to the end, away from the linear part, of the bent part, and the other end of the pull wire extends out of the linear part until the end, which deviates from the bent part, of the straight line part; the number of the drawing wires is four, and the four drawing wires are evenly arranged on the peripheral side of the bent part and extend towards the linear part along the axis of the soft lens till extending out of the linear part. According to the flexible lens, the four drawing wires are arranged, the four drawing wires are pulled respectively, so that the bending parts are bent in the direction of the pulled drawing wires, the bending direction is actually selected according to needs, the corresponding drawing wires are selected for pulling, and therefore four-direction bending is achieved, and the operation limitation that only two-direction bending exists in the prior art is avoided.

Description

technical field [0001] The disclosure belongs to the field of medical devices, and in particular relates to an electronic bronchoscope flexible mirror. Background technique [0002] In recent decades, with the development of science and technology, endoscopy and surgery have become routine diagnosis and treatment methods in the medical field. It can enter the patient's body through natural orifices or minimally invasive small openings, and directly observe and treat lesions, opening the door to minimally invasive surgery and bringing great progress to the medical field. [0003] With the development of science and technology, medical endoscopes are widely used in the medical field as tools for peeping and treating internal organs of the human body. During the development of medical endoscopes, it has undergone four major improvements, from the initial rigid tube medical endoscopes, half-curved medical endoscopes to electronic medical endoscopes, and to today's electronic me...

AI Technical Summary

Problems solved by technology

[0004] The electronic bronchoscope currently used in the market mainly has the following defects: the bending head of the flexible mirror is pulled by two wires to bend in the direction of the wire drawing, and only two-way bending can be realized, which has operational limitations.
