Abstract

The invention provides a multi-power internal stone breaker. A combined handle comprises an ultrasonic stone breaking assembly, a pneumatic ballistic stone breaking assembly and a laser stone breaking assembly. Ultrasonic stone breaking, pneumatic ballistic stone breaking and laser stone breaking are integrated, and a stone breaking way can be selected according to practical demands. Moreover, broken stones can be cleared no matter which way is selected, so that the stone breaking way is more flexible, and the stone breaking and stone clearing efficiencies are increased.

Description

technical field [0001] The invention relates to a lithotripter for calculus in the human body, in particular to a multi-power intracorporeal lithotripter integrating ultrasound, air pressure ballistics and laser. Background technique [0002] Ultrasonic lithotripsy in vivo is a better technique for minimally invasive treatment of stones. Generally, a probe with an ultrasonic transducer on the top is used to touch the stones through an endoscope to perform lithotripsy. Specifically, this lithotripsy technology uses the electrical oscillation generated by the ultrasonic generator to cause the ultrasonic transducer to generate high-frequency mechanical vibration, which is transmitted to the horn through the ultrasonic electrode, causing longitudinal vibration at the top of the ultrasonic probe. Hard stones create a stone-crushing effect on contact. The horn is a hollow probe, and the lavage fluid and calculus chips can be sucked out of the body by the vacuum negative pressure ...
