Abstract

The invention discloses a tail-end-bendable ultrasonic scalpel based on rope drive, and relates to the technical field of medical instruments, the tail-end-bendable ultrasonic scalpel comprises a scalpel head assembly, a transducer, a handle shell, a circuit board and a battery, and the front end of the transducer is in threaded connection with the scalpel head assembly. The snakelike joint structure based on the rope driving principle is adopted, a traditional ultrasonic energy transmission mode is innovated and improved, multi-angle and multi-direction flexible bending of the tail end of the tool bit is achieved, accurate movement of the tail end joint in multiple dimensions can be controlled by adjusting the tension of the steel wire rope at the position of the handle, and the tool bit can be flexibly bent in multiple directions. The scalpel can go deep into a complex anatomical area inside a human body, including a narrow or bent part which a traditional linear ultrasonic scalpel cannot reach, the snakelike joint structure enables the scalpel head to have good flexibility and controllability, a doctor can flexibly adjust the direction of the scalpel head according to the requirement in an operation, and therefore the scalpel head can be flexibly adjusted on the premise that the operation path is not changed. And multi-angle treatment of focus tissues is realized.
