An electric knife for breast cancer surgery

Abstract

The invention relates to the field of electric knife technology, in particular to an electric knife for breast cancer surgery, which includes a knife handle and a wire. The end is provided with a cutter head, and the handle is provided with a second groove along its length direction, the inner wall of the middle part of the second groove is connected with one end of the rotating rod through a rotating shaft, and the other end of the rotating rod It is threadedly connected with the fixed rod, and the end of the fixed rod away from the rotating rod is provided with a mounting groove, and a movable rod is inserted in the mounting groove, and a spring is connected between the movable rod and the inner wall of the mounting groove. , By turning the rotating rod, the sleeve is placed on different cutter heads, which can realize the rapid switching of the cutter heads, effectively improve the work efficiency, and keep the site clean.

Description

technical field [0001] The invention relates to the technical field of electric knife, in particular to an electric knife for breast cancer surgery. Background technique [0002] An electrosurgical scalpel is an electrosurgical instrument that replaces a mechanical scalpel for tissue cutting. It heats the tissue when the high-frequency and high-voltage current generated by the effective electrode tip contacts the body, and realizes the separation and coagulation of the body tissue, thereby achieving the purpose of cutting and hemostasis. [0003] In the prior art, there are many styles of electric knife heads, but basically a single electric knife is equipped with one knife head. Different knife heads are required for breast cancer surgery, and multiple electric knife heads need to be configured to use different knife heads. After multiple electric knives, the entanglement of the wires will easily cause confusion in the surgical environment; if the knife head is replaced, s...

Problems solved by technology

[0003] In the prior art, there are many styles of electric knife heads, but basically a single electric knife is equipped with one knife head. Different knife heads are required for breast cancer surgery, and multiple electric knife heads need to be configured to use different knife heads. After multiple electric knives, the wires are entangled with each other, which will easily cause confusion in the surgical environment; if the knife head is replaced, because the knife head itself has a certain temperature, it may burn the doctor or the patient if it is removed and operated carelessly
