Abstract

An air channel controlling system of three-way vacuum valve for the ballistic lithotriptor is composed of a handset module, three-way vacuum valve module consisting of the valve body with 4 air channels and the valve core with 3 air channels, the connecting flexible tube and high-pressure air pump. It has high successful rate and safety.

Description

technical field [0001] The invention relates to a medical device for pulverizing stones, in particular to a three-way vacuum valve gas path control system for ballistic lithotripters. Background technique [0002] In the treatment of human visceral stones, there are usually divided into extracorporeal lithotripsy and internal lithotripsy. Extracorporeal lithotripsy includes laser shock wave lithotripsy and ultrasonic lithotripsy, etc. This kind of lithotripsy system is less targeted to diseased tissues, and human organs are also damaged by shock waves or lasers, and the treatment effect is not good; now widely used is Internal lithotripsy systems, including mechanical and laser. The mechanical lithotripsy treatment system uses the change of gas pressure to push the probe of the mobile phone to directly act on the stone site, and promote the decomposition of the stone, and then excrete it from the body. For example, a patent with publication number 2173593 discloses a mecha...
