Technical Field

[0002] Surgical electrodes are a type of medical device that is usually used for electrosurgical cutting or electrocoagulation hemostasis during surgery. They use the high temperature generated by high-frequency current to cut tissue or stop bleeding. Cryogenic cold cutting is a method that combines cryogenic technology and electrosurgery. By cooling the cutting area of ​​the surgical electrode to a low temperature, it can reduce thermal damage and tissue adhesion during the cutting process, thereby improving surgical accuracy and treatment effects.

[0003] The existing surgical electrodes are basically composed of an upper shell, an electrode conductor, a conductive column and a lower shell. The conductive column is fixed inside the upper shell, and the electrode conductor is inserted into the conductive column through the lower shell. The upper shell is threadedly connected to the lower shell, and the inserted electrode conductor is limited by rotating the lower shell. During surgery, medical staff need to use electrode conductors of different shapes for surgery, and need to replace electrode conductors of different shapes. However, when replacing the existing electrode conductors, the medical staff needs to remove the lower shell before replacing the electrode conductor. At the same time, the medical staff needs to install the lower shell and the upper shell again to complete the replacement of the electrode conductor. The existing electrode conductor requires the medical staff to remove the lower shell before it can be replaced. This situation makes the replacement process of the existing electrode conductor more cumbersome, and at the same time reduces the work efficiency of the medical staff to a certain extent.

[0004] Therefore, it is necessary to provide a new low-temperature cold-cutting composite coating surgical electrode to solve the above technical problems. Utility Model Content
