Resecting device for living organism tissue utilizing ultrasonic vibrations

摘要

A medical resecting device is disclosed in which, a living organism tissue is resected with ultrasonic vibrations while the corresponding body cavity is observed with an optical observation pipe. The resecting device includes an ultrasonic vibrator for generating ultrasonic vibrations, a horn connected to the vibrator, a probe connected to the front portion of the horn to transmit the ultrasonic vibrations generated by the vibrator, the probe being provided with a rod-like shaft and a distal end portion with a resecting blade, a power source unit for supplying a drive voltage to the vibrator, and an optical observation pipe having a guide hole in which the shaft of the probe is inserted.
