DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for crushing and removing calculi in a body and an ultrasonic treatment apparatus for emulsifying and removing tissue in combination with a surgical operation or an endoscope.

[0002]

2. Description of the Related Art Generally, an ultrasonic therapy apparatus has a vibration transmitting member and an ultrasonic supplying means for supplying ultrasonic waves to the vibration transmitting member. The ultrasonic wave supply means includes an ultrasonic vibrator for generating an ultrasonic wave, and the ultrasonic wave supplied to the vibration transmitting member is transmitted through the inside of the ultrasonic vibration transmitting member and emitted at the tip. The ultrasonic waves radiated from this tip break the calculus and emulsify the tissue.

[0003] Preservation of blood vessels is known as an effect when an ultrasonic therapy apparatus is used for a surgical operation. However, in reality, fine blood vessels cannot be preserved and are resected.
This caused bleeding.

[0004] In consideration of such circumstances, Japanese Patent Application Laid-Open No. Hei 2-50

A connector receiving means for detachably attaching the first connector means, and a connector receiving means provided on the connector receiving means, wherein the first connector means is detachably attached to the first output end when the first connector means is connected to the connector receiving means. First A second instruction means having an input terminal and a second instruction means capable of instructing a predetermined second function operation different from the first function operation instructed by the first instruction means of the first operation unit; An operating unit, a second connector provided on the second operating unit and detachably attached to the connector receiving means, and a second connector provided at a predetermined position on the second connector, and A second connector for providing a second output terminal for outputting a second instruction signal at a predetermined position; and a connector provided on the connector receiving means, wherein the second connector is connected to the connector receiving means. A second input terminal detachably attached to the second output terminal, and a first instruction signal from the first input terminal and a first instruction signal from the second input terminal, provided on the main body. Based on the second instruction signal, And a control capable of controlling means and operation of the functional operation and the second function independently.

[0010]

According to the ultrasonic therapy apparatus of the present invention, the operation target of the switch at the time of use can be switched by selectively attaching and detaching operation units having different operation targets. Therefore, the ultrasonic therapy apparatus according to the present invention can prevent the unused switch from being in the way. Further, an electrical switching function is not required, and the configuration can be made at low cost.
