Description

Visual urethra expander

Technical Field

The utility model belongs to the technical field of urethral dilation and specifically relates to a simple structure, convenient to use, simple operation, visual degree height, avoid the visual urethral dilator of blind expansion.

Background

Urethral dilation, also known as urethral stricture dilation, is known. A surgical therapy for treating male urethral stricture is provided. The main indications are the prevention and treatment of inflammatory, traumatic and post-urethral surgery urethral stricture. The urethral stricture dilation for treating urethral stricture has the mechanical dilating effect on the stricture part and the massage effect to promote local blood circulation, scar softening and infiltration and absorption. In addition, urethral stricture dilation can be used as one of the measures for treating chronic prostatitis, chronic urethritis, mild bladder neck obstruction and other diseases, and has the function of detecting whether calculi or metallic foreign matters exist in the urethra or the bladder. The medical device used in urethral dilation is a urethral dilator.

At present, urethral stricture needs to be repeatedly expanded after more urethra fractures clinically, a metal expander is used at present, at least three times of urethral entry and exit needs to be blindly expanded from small to large, false tracts and urethral hemorrhage can be caused, a beginner with insufficient experience can even puncture the urethra to damage peripheral organs such as prostate and rectum, and operation treatment is needed in serious cases, in order to overcome the difficulty, the patent No. 2017206555440 is named as a visual electron mirror urethral expander, an electronic display screen is used for visual examination, urethral expansion is carried out through a balloon, but the balloon of the expander is arranged at the rear side of a visual urethra, only the position of the stricture can be seen during operation, then the expandable balloon needs to be continuously extended into the urethra, the expandable balloon is contacted with the stricture part of the urethra, and the process of expanding the balloon can not be completed under the direct vision, belong to the blind and expand, can not see the expansion condition of sacculus, also have the expansion risk, the sacculus structure is soft material moreover, and the narrow position of urethra probably just in time blocks in the middle part of sacculus, leads to the front and back both ends of sacculus inflation diameter respectively to be greater than the middle part diameter, can make the expansion effect low.
