Visual electronic mirror urethral dilator and application method thereof

Abstract

The invention discloses a visual electronic mirror urethral dilator and an application method thereof. The visual electronic mirror urethral dilator includes a display screen, a metal mirror pin, a saccule and a visual urethroscope. The front end of the metal mirror pin is connected to the display screen, and a saccule pressurization hole and a water flushing hole are disposed on both sides of thefront end of the metal mirror pin; The diameter of the saccule is 4.5 mm, the inside of the saccule is provided with a hole having a diameter of 2 mm, the tail end of the metal mirror pin passes through the hole and extends out of the saccule, and the saccule communicates with the saccule pressurization hole; and the visual urethroscope is disposed on the tail end of the metal mirror pin, and thevisual urethoscope is connected to the display screen through a conducting wire. The visual electronic mirror urethral dilator is simple in structure, is reasonable in design, can guide the dilator saccule to pass through a urethra narrow section under supervision of a display device, and gradually pressurizes the dilator saccule to make the urethra narrow section incarceratedly dilate, and so, damage is small, bleeding is less, dilatation is complete, a false passage does not occur, and surrounding visceral organs are not damaged. The visual electronic mirror urethral dilator is simple and easy to learn, is easy for beginners to master and is safe to operate, and complications of urethral dilation are reduced.

Description

technical field [0001] The invention relates to a urethral dilator, in particular to a visual electronic mirror urethral dilator. Background technique [0002] Urethral dilation, also known as urethral stricture dilation. A surgical treatment for male urethral strictures. The main indications are the prevention and treatment of inflammatory, traumatic and urethral strictures after urethral surgery. Urethral stricture dilatation for the treatment of urethral strictures, on the one hand, plays a role in mechanical expansion of the stenosis; In addition, urethral stricture dilation can also be used as one of the measures to treat chronic prostatitis, chronic urethritis, mild bladder neck obstruction and other diseases, and it can detect whether there are stones or metallic foreign bodies in the urethra or bladder. The medical device used in urethral dilation is a urethral dilator. [0003] Clinically, many urethral strictures after urethral rupture require repeated urethral...

Problems solved by technology

[0003] Clinically, many urethral strictures after urethral rupture require repeated urethral dilation. At present, metal dilators are used, which need to be blindly expanded at least three times to enter and exit the urethra, often causing false tracts and urethral bleeding. Inexperienced beginners It may even perforate the urethra and damage surrounding organs such as the prostate and rectum. In severe cases, surgical treatment is required
