Urethral probe for urethral catheter indwelling

Abstract

The invention relates to a urethral probe for urethral catheter indwelling. The urethral probe comprises a stainless steel probe body, the stainless steel probe body is a cylindrical shell formed by a body I and a body II in a butt-joint mode, the section of the body I and the section of the body II are semicircular, rhombic clamping strips are arranged at the two butt-joint ends of the body I and are arranged in the length direction of the body I, rhombic clamping grooves matched with the shapes of the rhombic clamping strips are formed in the two butt-joint ends of the body II, a gap matched with the wall thickness of the body I is formed in the end, far away from the body II, of each rhombic clamping groove, and when the body I and the body II are in butt joint, the rhombic clamping strips of the body I are arranged in the rhombic clamping grooves of the body II. According to the urethral probe, the urethra can be expanded, meanwhile, a urethral catheter can indwell, the hardness of the existing urethral catheter is increased, the toughness of the pointed end of the urethral catheter is ingeniously utilized for expanding the urethra, and hurt of the pointed end of an existing metal probe to the urethra and fake urethra forming are avoided.

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...
