Scalpel rod structure of ultrasonic scalpel and ultrasonic scalpel

Abstract

The invention discloses a scalpel rod structure of an ultrasonic scalpel and the ultrasonic scalpel, and belongs to the technical field of medical instruments. The scalpel rod structure comprises an operating handle, an exhaust hole is formed in the bottom of a suction cavity, an exhaust fan is fixedly installed in the suction cavity, a reversing poking wheel is rotationally connected into an installation groove, an installation sleeve is fixedly connected to the front end of the operation handle, a threaded ring is rotationally connected to the outer wall of the installation sleeve, a positioning ring is slidably connected to the outer wall of the installation sleeve, an exhaust pipe is connected to the front end of the installation sleeve, and a pressing plate is connected to the side wall of the operation handle. The scalpel rod structure comprises an inner pipe and an outer pipe, the outer wall of the outer pipe is fixedly connected to a connecting disc, a limiting sleeve is fixedly connected to the side wall of the connecting disc, the end of the outer pipe is fixedly connected to a matching disc, the side wall of the matching disc is fixedly connected to a connecting post, the end of the limiting sleeve is fixedly connected to a fixed ring, and the front thread of the inner pipe is in thread connection with a cutting knife. According to the invention, the scalpel cannot be damaged, control and cutting reversing are facilitated, the sight of a surgical site can be conveniently and timely cleaned through operation, and surgical observation and operation of doctors are facilitated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a knife bar structure of an ultrasonic knife and the ultrasonic knife. Background technique [0002] Ultrasonic scalpel uses ultrasonic energy to process soft tissue, cutting and coagulation are completed at the same time, and can ensure minimal lateral thermal damage to tissue. Intended for cutting soft tissue where bleeding control and minimal thermal damage are required. Ultrasonic scalpels are essential surgical instruments in various minimally invasive surgeries. The ultrasonic knife is mainly composed of the host, the drive handle and connection, the knife head and the foot switch; its working principle is to use the pedal or the hand-held knife head to activate the work. At this time, the host outputs the electric energy at the resonant frequency of the vibration system to the drive handle. , the drive handle converts electrical energy into mechanical energy and ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a knife bar structure of an ultrasonic knife and an ultrasonic knife to solve the problem that the clamping force produced by the two is difficult when the cutting head at the front end of the knife bar assembly and the ultrasonic action bar are closed and clamped. Control, when the clamping force is too large, the shear head will cause damage to the ultrasonic action rod. Because the ultrasonic knife uses heat to cut and separate tissues, it will generate smoke, which will easily affect the field of vision. It is more obvious in deep anatomical positions with small spaces. It is easy to affect the operator's operation and increase the operation time
