Disposable flexible ureteroscope device

Abstract

Provided is a disposable flexible ureteroscope device. The front end of a cannula is in a hard, slightly-thin and integrally metal structure and convenient for insertion. The interior of the cannula is equipped with a miniature camera shooting module composed of a miniature lens having a miniature image sensing chip and a miniature illumination module. The bending part of an insertion tube in themiddle segment of the cannula is composed of two parts including an active bending tube and a passive bending tube in order to achieve two-way bending. The cannula internally comprises a working passage, cables and steel wire limiting grooves. An insertion tube at the back segment of the cannula is connected with a handle through a handle insertion tube opening. A connecting wire of the miniatureimage sensing chip is connected with a handle data interface at the back end of the handle through the cables. The handle is connected with a host through a data line. The host is connected with a monitor and a computer or a mobile terminal. The French perimeter of a cross section at the front end of the insertion tube is shortened as much as possible in order to alleviate the pain of a patient. The high-resolution miniature camera shooting module is adopted. The French perimeters of the miniature image sensing chip and the lens are 3.82 Fr. The optical effect and the image definition are greatly enhanced. The resolution ratio is no less than 160 thousand pixels, which is convenient for a doctor to perform a surgery for disposable use.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a disposable electronic flexible ureteroscope device. Background technique [0002] At present, many hospitals still use flexible ureteroscopes with fiberoptic endoscope technology. Therefore, under the clinical requirement that the outer diameter should not be too thick, flexible ureteroscopes have the characteristics of low resolution. Operation can also easily lead to fiber breakage in the soft mirror. [0003] In addition, although there are flexible ureteroscopes with imported electronic endoscope technology, they are expensive and can only be sterilized and reused many times, but they cannot be used in consecutive operations. [0004] Patent application number 201510199054.X "disposable soft ureteral catheter" only provides a catheter whose working part is a soft multi-lumen tube. The soft multi-lumen tube includes an entry part, a turning part, and a working rear part. A...

Problems solved by technology

At the same time, there is also a wire rope inside the tube. One end of the wire rope is connected to the head end cap at the end of the multi-lumen tube, and the other end is connected to the push rod of the handle of the operation part. The axis line of the wire channel and the axis line of the instrument channel are always at the same On the plane, it solves the problem that the existing hose operation is not flexible enough and accurate
