Abstract
A medical treatment apparatus utilizing ultrasonic waves according to this invention is applied to treatments such as breaking up a stone formed in a living body. The medical treatment apparatus utilizing ultrasonic waves includes a vibration generator (10) for generating ultrasonic vibrations and a vibration transmission member (16) for transmitting the ultrasonic vibrations generated by the vibration generator (10). The vibration transmission member (16) has a front end portion and a proximal end portion which is mounted on the vibration generator (10). The medical treatment apparatus further includes a cover member (20) for surrounding the outer surface of the vibration transmission member (16) and an exposing member (21) for exposing the distal end portion of the vibration transmission member (16) outside the cover member (20). When the vibration transmission member (16) is inserted into an endoscope channel and a body cavity, the distal end of vibration transmission member (16) does not damage them since the distal end is sealed with the cover (20).
