Description

TECHNICAL FIELD

[0002] In clinic, some patients have difficulty in urination due to anesthesia, urethral infection, reduced bladder contraction performance, prostate hyperplasia and pathological urethral stricture, etc., and must rely on catheterization to assist urination. Catheterization refers to inserting a catheter into the urethra to the bladder to drain urine. Catheterization is divided into catheter retention catheterization and intermittent catheterization. The former is to insert the catheter into the patient's body for a period of time after successful catheterization, and the catheter is removed as soon as possible when the condition permits, and the catheter must be replaced regularly if necessary. The latter is to catheterize every 4-6 hours, and the catheter is removed immediately after the bladder is emptied.

Some patients have urethral stricture or severe prostate hyperplasia, and their urethral cavity is small, the bending degree is increased and may lack elasticity. In this case, it is difficult to use the traditional catheter for catheterization, even for experienced urologists. In this case, inserting a pre-bent steel stylet into the urethral cavity to increase the bending resistance of the catheter can solve part of the difficult urethral catheterization, but this method also has a high failure rate, and may cause urethral perforation in an invisible state, and even cause rectal perforation behind the urethra.
