Abstract
The treatment section integrally includes, on the distal side of a probe, a cortical bone abrasion portion which abrades a living body tissue or a bone among treated target parts by mechanical abrasion by ultrasonic vibration, and a cartilage abrasion portion which generates heat by ultrasonic vibration and abrades a cartilage among the treated target parts by dissolutive abrasion.
Claims9
An ultrasonic treatment instrument for articulations, comprising:
- an ultrasonic vibration generator configured to generate ultrasonic vibration;
- an ultrasonic probe configured to transmit the ultrasonic vibration;
- and
- a treatment section provided at a distal end of the ultrasonic probe and configured to perform a desired treatment on a treated target part,
- the treatment section comprising:
- a bone abrasion portion configured to come in contact with a living body tissue or a bone of the treated target part by a surface having an edge, and to configured to mechanically abrade the living body tissue or the bone by beating the living body tissue or the bone by the transmission of the ultrasonic vibration;
- and
- a cartilage abrasion portion provided at a different position from, or at an identical overlapping position to, a position of the bone abrasion portion, configured to come in contact with a cartilage of the treated target part, and configured to generate heat by the transmission of the ultrasonic vibration and to dissolutively abrade the cartilage.
