Abstract

The invention discloses an ultrasonic scalpel. The ultrasonic scalpel comprises a handle, a middle rod, a rear bending connecting part, a rigid cutter bar, a cutter head and a front bending connecting part, wherein the rear bending connecting part is arranged between the handle and the middle rod; the rigid cutter bar is connected with the middle rod; the front bending connecting part is arranged between the rigid cutter bar and the cutter head; a front bending part and a rear bending part comprise a plurality of joint sheets and four transmission steel wires for connecting the plurality of joint sheets in series; the middle rod is provided with an accommodating cavity; a piezoelectric transducer is arranged in the accommodating cavity; a tail mass block is positioned at the rear end of the piezoelectric transducer; the middle rod is connected with the rigid cutter rod through an ultrasonic amplifier; and a locking device for maintaining the bending angle after the front bending connecting part and the rear bending connecting part are bent is arranged on the middle rod. According to the ultrasonic scalpel, the tail mass block is arranged on the rear part of the piezoelectric transducer, so the defect of ultrasonic energy attenuation caused by the bending parts is overcome and the cutting effect is guaranteed.

Description

technical field

[0001] The invention relates to the technical field of scalpels, and more specifically relates to an ultrasonic scalpel. Background technique

[0002] The traditional scalpel is composed of a handle and a blade. During the operation, a sharp blade is used to cut human cells and tissues. The blades are all disposable. The traditional scalpel is simple in structure, cheap, and widely used. However, the traditional scalpel When cutting human cells and tissues, the cutting effect is poor. In order to achieve the cutting effect, it is often necessary to perform multiple cuts, which is not conducive to wound healing. Moreover, the amount of bleeding during the cutting process is relatively large, so there is a surgical electric knife. Surgical electric knife The knife will apply a high-frequency current to the human body, and the Joule heat generated by the load or contact resistance at this time will instantly heat the cell tissue to vaporize it, and finally cut t...
