AI Technical Summary

Technical Problem

During the cutting or coagulation process of existing disposable plasma surgical electrodes, blood stains are prone to adhere to the surface of the electrode's plastic handle and flow into the internal conductive area, resulting in high-voltage leakage and arc burns, which poses a greater medical risk.

Method used

A plasma surgical electrode that prevents water from being injected by switches is designed. By adding a waterproof ring at the cutting and coagulation button switch positions, and improving the structure between the button switch and the corresponding position on the control circuit board, the structure is a whole silicone sealing block to enhance the waterproof sealing.

Benefits of technology

It effectively reduces the risk of blood stains flowing into the conductive area inside the electrode plastic handle during electrode cutting or coagulation, improves operation safety, and does not make excessive changes to the electrode structure, which is easy to operate and low cost.
