Problems solved by technology

Clinically, most of the urethral dilation is successful, but the catheter is still difficult to insert, resulting in catheterization failure
Seriously restricting the application of urethral probes and indwelling catheterization, which has added a lot of trouble to urologists, and also caused great mental, physical and economic burdens to patients and their families
[0003] At present, there is no special medical device in China that can dilate the urethra and indwell catheterization under direct vision

Embodiment Construction

[0025] As shown in the figure, the visible type is used for indwelling catheter urethral probe, including the probe body, outer sheath and imaging device;

[0026] Described imaging device comprises casing 301, camera 302, display screen 303, photoelectric converter 304 and photoelectric signal converter 305, and camera 302 is embedded on the housing 301, and the output end of camera 302 is connected with photoelectric converter 304 , the photoelectric converter 304 converts the optical image transmitted from the camera 302 into an electrical signal, the photoelectric signal converter 305 converts the electrical signal into a color video signal and outputs it to the display screen 303, and the display screen 303 is rotatably arranged on the casing 301, the The imaging device is an existing commonly used imaging device, which is widely used in minimally invasive medical devices such as laparoscopes and electronic gastroscopes. The camera 302 is an infrared camera, which is mainl...

Abstract

The invention relates to a visible urethral sound for an indwelling catheter. The visible urethral sound comprises a sound main body, an outer sheath and a development device. The visible urethral sound is a special medical instrument which can achieve urethral dilatation and retention catheterization in direct view, so that a doctor can clearly observe the insertion process during carrying out an operation and convenience is brought for the doctor to operate. Therefore, the operation success rate and safety are high, and retention catheterization for urethrostenosis, urethral obstruction and urethral disruption patients is realized to greatly relieve the pain of the patients.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a visible urethral probe for indwelling a urinary catheter and a method of use thereof. Background technique [0002] Urethral stricture, obstruction, rupture, and acute urinary retention are common diseases in urology, more common in men, and the main causes are trauma, benign prostatic hyperplasia, etc. The fundamental method of treatment is to dilate the urethra and place a urinary catheter. However, because the operation cannot be done under direct vision, dilation often fails, and even serious complications such as urethral hemorrhage and iatrogenic urethral false tract formation occur. Clinically, most of the urethral dilatation is successful, but the catheter is still difficult to insert, resulting in catheterization failure. Seriously restricting the application of urethral sounding and indwelling catheterization, this has added a lot of trouble to urologists, and has al...
