Treatment apparatus and treatment device for surgical treatments using ultrasonic vibration
First Claim
1. An ultrasonic treatment device comprising:
- a transducer unit equipped with an ultrasonic transducer generating ultrasonic vibration in response to supply of power;
a probe unit configured to have a treatment member at a distal end thereof, detachably loaded to the transducer unit, and equipped with an ultrasonic probe transmitting the ultrasonic vibration to the distal end of the treatment member when the transducer unit is loaded to the probe unit;
a main unit which is adapted to be manually grasped by an operator, to which the probe unit with the transducer unit loaded thereto is detachably loaded, and which has a cylindrical insert through which the ultrasonic probe is inserted and positioned within, to have the treatment member protruded outwardly when the probe unit is loaded and an outer sheath detachably covering an outer surface of the insert;
an electric connector disposed at a base end of the outer sheath and electrically connected to a power source for electric cautery; and
an electric connecting portion connected to the electric connector and configured to allow the electric connector to be connected electrically to the ultrasonic probe when the outer sheath is loaded to the main unit; and
whereinthe electric connecting portion is located to contact a portion of the ultrasonic probe at a node of vibration thereof, when the outer sheath is loaded into the main unit.

Abstract
An ultrasonic treatment device comprises a transducer unit, probe unit, and a main unit. The transducer unit comprises an ultrasonic transducer generating ultrasonic vibration in response to supply of power. The probe unit has a treatment member at a distal end thereof. The probe unit is detachably loaded to the transducer unit, and is equipped with an ultrasonic probe transmitting the ultrasonic vibration to the distal end of the treatment member when the transducer unit is loaded to the probe unit. The main unit is manually grasped by an operator. The probe unit with the transducer unit loaded thereto is detachably loaded to the main unit. The main unit has a cylindrical insert through which the ultrasonic probe is inserted to have the treatment member protruded outwardly when the probe unit is loaded. The main unit further has an outer sheath detachably covering an outer surface of the insert.
