Abstract

An ultrasonic scalpel handle, an ultrasonic scalpel and an ultrasonic scalpel system, wherein the ultrasonic scalpel comprises the ultrasonic scalpel handle and cutting tool. The cutting tool comprises an inner tube, an outer tube and a tool bar which extend in the front-rear direction, wherein the tool bar is disposed through the inner tube and the outer tube is sleeved outside the inner tube. The ultrasonic scalpel handle comprises a handle housing and a transducer assembly. The transducer assembly at least comprises a transducer having a horn shaft which extends in the front-rear direction. A novel connection assembly is disposed inside the ultrasonic scalpel handle and achieves stable and reliable connection between the cutting tool and the ultrasonic scalpel handle. Thus the cutting tool is easy to mount and operate, does not shake during a surgery operation, has better operation accuracy.
