Ultrasonic scalpel capable of rapidly replacing scalpel bar in operation process

Abstract

The ultrasonic scalpel comprises a handle, a rotating assembly is arranged at one end of the top of the handle, the scalpel rod is arranged in the middle of the rotating assembly in a penetrating mode, an auxiliary assembly matched with the scalpel rod is arranged in the top end of the handle, and a transducer connected with one end of the scalpel rod is arranged on one side of the auxiliary assembly; a plurality of bases are arranged at the bottom end of the transducer, and a connecting wire is arranged at one end of the transducer; a control handle is arranged at one end of the bottom of the handle, and a lantern ring is arranged at the top of one side of the handle. The surgical knife is reasonable and compact in structure and convenient to operate, the knife bar can be quickly mounted and dismounted, so that a worker can quickly replace the knife bar in the process of performing an operation on a patient, the handle can be repeatedly used, and the surgical knife is convenient to use. And therefore, the use time for replacing the cutter bar by a worker in the operation process can be shortened, meanwhile, the use cost is also reduced, and the waste of resources is avoided.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an ultrasonic scalpel that can quickly replace a knife bar during an operation. Background technique [0002] Ultrasonic scalpel is a high-frequency electrosurgical device, which is mainly used for cutting biological tissue and closing blood vessels. It has the characteristics of less bleeding, less damage to surrounding tissues, and quick recovery after surgery. It acts on human tissue to cut and coagulate, without causing side effects such as tissue drying and burns, and there is no current through the human body when the cutter head works. , has a wide range of applications in the operating room, known as a bloodless scalpel. [0003] Among them, the patent number CN109044491B discloses an ultrasonic scalpel, which includes a handle, an ultrasonic transducer, an ultrasonic conduction rod assembly, a casing clamp assembly and a waterproof sleeve, and the ultrasonic...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a configuration method, which has the advantages of quickly changing the knife rod during the operation and improving the stability when holding the ultrasonic scalpel, and then solves the problem of slow installation efficiency of the new casing clamp assembly. And in the prior art, it is impossible to improve the stability of the doctor's hand-held ultrasonic scalpel.
