Ultrasonic treatment device
TLDR
An ultrasonic treatment device (21) comprises an ultrasonic vibrator (28) which generates ultrasonic vibration, a vibration transmission section (29), a treatment section (32), and a pad member (49) which is provided to the grip member (33) at a position facing the treatment section.Abstract:
An ultrasonic treatment device (21) comprises an ultrasonic vibrator (28) which generates ultrasonic vibration, a vibration transmission section (29) which transmits the ultrasonic vibration generated by the ultrasonic vibrator (28), a treatment section (32) which is formed at the front end of the vibration transmission section (29) and transmits to living organism's tissue the ultrasonic vibration transmitted from the vibration transmission section (29), a grip member (33) which is provided so that the grip member (33) can be opened and closed relative to the treatment section (32), and a pad member (49) which is provided to the grip member (33) at a position facing the treatment section (32) and which makes contact with the treatment section (32) when the grip member (33) is in a closed state. The front end of the pad member (49) has a protrusion section (60) which, on the side thereof which faces the treatment section (32), protrudes toward the treatment section (32).read more
