AI Technical Summary
High-frequency surgical electrodes lack a telescopic protective structure, and the working end of the electrode is exposed to the outside for a long time, making it easy to be contaminated or damaged. In addition, the extension length is not adjustable, which makes it difficult to meet the needs of different surgical sites and poses a safety risk.
A retractable high-frequency surgical electrode device was designed. The device uses a protective mechanism to protect the working end of the electrode from retraction. The mechanism includes components such as a protective tube, a guide tube, an adjustment frame, and an adjustment rod. It can precisely adjust and lock the extension length of the electrode, and uses a ruler and a pin to improve the intuitiveness and accuracy of the adjustment.
It achieves telescopic protection of the electrode working end to prevent contamination and damage, ensures precise adjustment of the extension length, reduces the risk of accidental scratches, and adapts to the needs of different surgical sites.
