Abstract
The invention discloses an ultrasonic scalpel capable of improving cutting and hemostatic effects simultaneously. The ultrasonic scalpel comprises a piezoelectric ceramic body, an amplitude-change pole and a scalpel head which are connected sequentially from far to near, inclined cutting grooves are formed in the front segment of the near end of the amplitude-change pole, a transverse splitting slot is formed in the front end of the scalpel head and divides the scalpel head into two pieces, and the scalpel head and the amplitude-change pole convert longitudinal vibration of a transducer into compound vibration formed by producing transverse vibration at the front end of the scalpel head. The ultrasonic scalpel capable of improving the cutting and hemostatic effects simultaneously has the advantages that blood is coagulated more effectively through ultrasonic vibration perpendicular to cutting surfaces, and the shape cutting edge can cut rapidly, so that the defect that a traditional ultrasonic longitudinal-vibration scalpel is bound to be used for either cutting or hemostasis is made up; the transverse vibration at the front end of the scalpel head with the splitting slot is amplified locally, so that efficiency of an integral ultrasonic vibration system is also improved.
