Ultrasonic scalpel handle

Abstract

An ultrasonic scalpel handle, comprising a handle housing () and a transducer assembly (). The transducer assembly () is integrally accommodated in the handle housing () and can rotate about its own axis. The transducer assembly () comprises a transducer shell () and a transducer () fixedly disposed to each other, and a conductive member () fixedly provided outside the transducer shell (). The conductive member () has at least a conductive portion. The transducer () is fixedly and electrically connected to the conductive portion. An electric element () is further fixedly provided in the handle housing (). In the process that the transducer assembly () rotates about its own axis with respect to the handle housing (), the electric element () is always in contact with the conductive portion to maintain electric connection. In this way, in the process that the transducer assembly rotates about its own axis in the handle housing, power cord does not rotate with it, and the power cord may further extend in the lower part of the handle, such that a series of problems of heavy burden on the arm and easy fatigue, and knotting of the power cord, etc. caused by the power cord extending from the rear portion of the handle housing are avoided.
