Abstract
Abstract A hand-piece comprises an arm main body which moves relative to a grip section, and an arm section having a clamp member openable and closable with respect to a probe section. As a result of movement of the arm main body relative to the grip section, the clamp member is shifted between a closure position in which the clamp member cooperates with the probe section to hold living tissue between the clamp member and the probe section, and an open position in which the clamp member is separated from the probe section to release the living tissue.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
213 words
An ultrasonic medical instrument which transmits ultrasonic oscillation to living tissue to thereby perform an ultrasonic treatment of the livings tissue, the ultrasonic medical instrument comprising: an instrument main body including an oscillator which generates ultrasonic oscillation, an oscillator cover which covers the oscillator, a transmission section which amplifies and transmits the ultrasonic oscillation from the oscillator, and a probe section provided at a distal end of the transmission section which contacts the living tissue and transmits to the living tissue the ultrasonic oscillation from the transmission section; and operation means including an operation section extending from the oscillator cover toward the probe section along the instrument main body, and a clamp body provided at a distal end of the operation section and opposed to the probe section such that the clamp body is openable and closable with respect to the probe section, wherein the operation means shifts the clamp body, as a result of movement of the operation section relative to the instrument main body, between a closure position in which the clamp member cooperates with the probe section to hold the living tissue between the clamp body and the probe section, and an open position in which the clamp body is separated from the probe section to release the living tissue.
