Urethral dilator used together with urethral probe

Abstract

The invention provides a urethral dilator used together with a urethral probe. The dilator completely closely covers the urethral probe; the back end of the dilator is provided with a urethral probe insertion port, the back part of the dilator is provided with an air inlet, the middle section of the dilator is provided with an aerating channel connected with the air inlet, and the front end of the dilator is provided with an air cell connected with the aerating channel. The urethral dilator can be used together with the urethral probe with a corresponding size, high-pressure gas or high-pressure liquid can be charged in the inflatable air cell on the premise of detecting the narrow position of the urinary tract by the hard urethral probe to apply the horizontally acting force generated by the expansion of the air cell to the narrow position of the urinary tract, so that the urethral false passage caused when surrounding tissues are much easily damaged as the urethral probe is commonly forced to dilate the narrow position of the urinary tract is effectively avoided, and the effect of dilating the narrow position of the urinary tract is improved. The urethral dilator can be used together with the conventional urethral probe and conveniently produced and used, so that by using the urethral dilator, the occurrence of the iatrogenic urethral false passage is greatly lowered, and the pains in patients are relieved.

Description

technical field [0001] The invention relates to a urethral dilator, in particular to a urethral dilator sleeved on the surface of a urethral probe and used in conjunction with the urethral probe. Background technique [0002] Urethral stricture is a common disease in urology, and the common causes of the disease are urethral trauma, inflammation, and postoperative scar formation. There are many methods to treat urethral stricture, the simplest and most commonly used method is urethral dilatation, most of which can be performed in outpatient clinics, most of which use metal urethral probes to dilate the narrow urethra. However, due to various reasons, dilation failure often occurs, and even serious complications such as urethral hemorrhage and iatrogenic urethral false formation occur. [0003] Most of the occurrence of iatrogenic false urethra is caused by the forced use of metal urethral probes to dilate the narrow urethra. In the progressive expansion of the urethra, whe...

AI Technical Summary

Problems solved by technology

In the progressive expansion of the urethra, when a larger urethral probe enters and passes through the stricture of the urethra, the urethral probe will follow the "violence" in the longitudinal direction of the urethra to expand the narrow urethra, but it is difficult to control the "violence" in the longitudinal direction. Force and angle, often puncture the normal tissue next to the narrow urethra, resulting in the formation of a urethral false tract

At present, there is still no effective prevention and treatment method for the false urethra caused by the forced expansion of the urethral probe, which seriously restricts the use of the urethral probe. Great mental, physical and financial burden
