Abstract

The invention relates to the technical field of medical instruments, in particular to an anti-injury cystoscope feeding device for urethral prostate surgery, which comprises an outer support, a guide part and a plurality of urethral dilatation parts, the outer support is mounted on an operating handle part, the urethral dilatation parts are detachably connected to the guide part, and the urethral dilatation parts are detachably connected to the guide part. The urethra dilatation part expands in the radial direction and in the axial direction at the working temperature, the cystoscope feeding device cannot rub the mucous membrane on the inner wall of the urethra in the feeding process and the taking-out process, and damage to the urethra caused by a prostate operation is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anti-injury cystoscope delivery device for urethra and prostate surgery. Background technique [0002] Cystoscope is a kind of endoscope. It needs to be used in the operation or detection of bladder cancer. The cystoscope needs to enter the bladder through the urethra when it is used, and there are some small mesh holes on the outer tube wall of the cystoscope. , when the cystoscope enters the urethra, the mesh holes rub against the urethra, which may damage the urethral mucosa and form urethral stricture, which will bring pain and unnecessary risks to the patient during the later treatment process. A stent is implanted in the urethra to protect the urethra. [0003] The stent tube in the prior art is a circular tube. When in use, the stent tube enters the urethra from the outer opening of the urethra and extends into the body along the urethra until the end of the st...
