Abstract

A joint surgical treatment includes bringing a treating portion of an ultrasonic device into contact with a damaged region of a cartilage that is a treated object region in the joint, and transmitting an ultrasonic vibration to the treating portion in contact with the treated object region while observing the treated object region with the arthroscope to remove the treated object region of the cartilage. The ultrasonic vibration is used to remove the treated object so as to smoothly continue a removed surface from which the treated object region is removed and a non-removed surface adjacent to the removed surface without forming any corners between the surfaces in the cartilage.

First claim

What is claimed is:

1. A joint surgical treatment which is to be performed under an arthroscope, the surgical treatment comprising:
inserting the arthroscope and a treating portion of an ultrasonic device into a joint;
bringing the treating portion of the ultrasonic device into contact with a damaged region of a cartilage that is a treated object region in the joint; and
removing the treated object region of the cartilage by transmitting an ultrasonic vibration to the treating portion in a state where the treating portion is in contact with the treated object region while observing the treated object region with the arthroscope, and smoothly continuing a removed surface from which the treated object region is removed and a non-removed surface adjacent to the removed surface without forming any corners between the surfaces in the cartilage.

2. The surgical treatment according to claim 1 ,
wherein the removing the damaged region of the cartilage by the ultrasonic vibration includes forming a dented region having a substantially circular cross section on the removed surface.
