Novel bipolar radiofrequency plasma knife

Abstract

The invention discloses a novel bipolar radiofrequency plasma knife. The novel bipolar radiofrequency plasma knife comprises a handle, a power line, a plug and an inner core; the handle comprises a main handle and an auxiliary handle, an auxiliary handle connecting column is arranged at the upper end of the main handle and internally provided with an inner core connecting mechanism, one end of the auxiliary handle is installed on the auxiliary handle connecting column, an inner core protective tube is arranged at the other end, the auxiliary handle can slide on the auxiliary handle connecting column in the axial direction, and a spring is arranged in the auxiliary handle; the inner core is inserted into the inner core protective tube, one end of the inner core is connected with the inner core connecting mechanism, and an electrode is arranged at the other end of the inner core; one end of the power line is connected with the inner core connecting mechanism, and the other end of the power line is connected with the plug. The novel bipolar radiofrequency plasma knife has the advantages of being simple in structure, convenient to operate and capable of conducting comprehensive disinfection.

Description

technical field [0001] The invention relates to a novel bipolar radio frequency plasma knife, which belongs to the field of medical equipment. Background technique [0002] A plasma knife is a surgical tool that simultaneously cuts and cauterizes tissue and is a commonly used medical device. In the prior art, commonly used plasma knife structures such as figure 1 As shown, the tool bar assembly 100, the electrode body 200, the handle 300 and the power cord 400 are included. The tool bar assembly 100, the electrode body 200 and the handle 300 are coaxially arranged, and the whole is a linear structure. [0003] There are many shortcomings in the plasma knife of existing structure, for example: [0004] 1. The overall structure is linear, and more than 300 handles adopt a cylindrical structure. On the one hand, it is easy to slip, and on the other hand, it is easy to cause soreness in the wrist after long-term use; [0005] 2. Surgical instruments need to be strictly steril...

AI Technical Summary

Problems solved by technology

[0004] 1. The overall structure is linear, and more than 300 handles adopt a cylindrical structure. On the one hand, it is easy to slip, and on the other hand, it is easy to cause soreness in the wrist after long-term use;

[0005] 2. Surgical instruments need to be strictly sterilized after each use. However, due to the existing structure, the outer sleeve of the electrode body 200 and the handle 300 are integrated, which cannot be disassembled, and the sleeve of the electrode body 200 and the The spacing between the inner cores is very small, so it is difficult to achieve complete disinfection;

[0006] 3. The connection between the power cord 400 and the handle 300 is often bent, which may easily cause the connection to break

[0007] 4. The end of the electrode body 200 is usually a linear structure, and the working range is very limited
