Abstract
Description
technical field
[0001] The invention relates to the technical field of medical instruments, in particular to a urethral probe for indwelling a urinary catheter. Background technique
[0002] Urinary retention is a common emergency in urology, which requires emergency catheterization. For patients with urinary retention caused by urethral stricture caused by prostatic hypertrophy, trauma, and tumors, an indwelling catheter is also required. However, most of the catheters currently used clinically are made of natural rubber, silicone rubber or polyvinyl chloride (PVC), which have certain flexibility. For patients with urethral strictures, the catheters often cannot be inserted, resulting in Urinary failure. For this reason, urethral dilation is required, and most of the urethral probes used clinically are metal probes. During the dilation process, due to the existence of the physiological curvature of the urethra and the invisibility of dilation, the risk of dilation is relat...
