AI Technical Summary
Existing urinary catheters have a single function and cannot perform multiple procedures.
A functional hole is provided on the occlusion head of the urinary catheter and connected to the main channel, so that medical instruments such as guide wires can be inserted into the bladder through the functional hole to perform various operations. At the same time, the functional hole and the occlusion head are not on the same axis to avoid blockage.
This allows for various procedures to be performed after the catheter is inserted into the bladder, and the functional opening is less likely to be blocked by debris in the urethra, making it more convenient to use.
