Abstract

An elbow joint surgical treatment includes transmitting an ultrasonic vibration to a treating portion of an ultrasonic device to excise the treated object region of the synovial membrane, and bringing the treating portion of the ultrasonic device, used in excising the synovial membrane, to come in contact with an osteophyte positioned in one of a coronoid fossa of a humerus, an olecranon fossa of the humerus, a coronoid process of an ulna, and an olecranon. The surgical treatment includes transmitting an ultrasonic vibration to the treating portion in contact with the osteophyte to remove the osteophyte.

First claim

What is claimed is:

1. An elbow 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 an elbow joint;
excising a treated object region of a synovial membrane by transmitting an ultrasonic vibration to the treating portion in a state where the treating portion is in contact with the treated object region of the synovial membrane while observing the treating portion of the ultrasonic device and the treated object region of the synovial membrane with the arthroscope;
bringing the treating portion of the ultrasonic device, used in excising the treated object region of the synovial membrane, to approach and come in contact with an osteophyte that is a treated object region positioned in one of a coronoid fossa of a humerus, an olecranon fossa of the humerus, a coronoid process of an ulna, and an olecranon; and
removing the osteopyte by transmitting an ultrasonic vibration to the treating portion of the ultrasonic device in a state where the treating portion is in contact with the osteophyte while observing the treating portion and the osteophyte with the arthroscope.

2. The surgical treatment according to claim 1 ,
wherein the ultrasonic vibrations of different amplitudes are transmitted to the treating portion of the ultrasonic device for use in excising the treated object region of the synovial membrane and removing the osteophyte.

3. The surgical treatment according to claim 2 ,
wherein the amplitude of the ultrasonic vibration in excising the treated object region of the synovial membrane is smaller than the amplitude of the ultrasonic vibration in removing the osteophyte.
