AI Technical Summary

Technical Problem

During the advancement of existing prostate dilators, the friction between the guide head and the inner wall of the prostate causes discomfort to the patient, and the friction between the airbag and the inner wall also causes discomfort. The lubricant is easily eliminated quickly, reducing comfort.

Method used

A prostate dilator is designed. Lubricant injection holes are provided around the guide head. Lubricant is injected while advancing. The balloon section of the catheter is concave inward to reduce friction. The balloon skin is tightly attached to the catheter to reduce contact with the inner wall of the prostate.

Benefits of technology

Effectively reduces patient discomfort during expander advancement, improving treatment comfort through continuous lubrication and reduced friction.

Abstract

A prostate dilator belongs to the technical field of medical instruments and comprises a catheter, the front end of an imbedding end of the catheter is a hemispherical guide head, and a plurality of lubricant injection holes are formed in the periphery of the central point of the catheter; a medicament injection hole is formed in the catheter behind the guide head; a gas inlet and outlet hole is formed in the catheter of the air bag section, a lubricant tube, a medicament tube and an inflation tube are arranged in the catheter, the lubricant tube is communicated with the lubricant injection holes, the medicament tube is communicated with the medicament injection holes, and the inflation tube is communicated with the gas inlet and outlet hole; the lubricant tube, the medicament tube and the inflating tube respectively extend out of the tail part of the operation end and are respectively connected with an injector; the prostate dilator has the advantages that when the prostate dilator is propelled, lubricant can be injected while the prostate dilator is propelled, the air bag skin can be tightly attached to the sunken air bag section through the sunken portion, friction of the catheter to the inner wall of a prostate can be effectively reduced on the whole, and discomfort of a patient is relieved.
