AI Technical Summary
In the prior art, the electrode handle clamping assembly has the problem of electrode falling off. In the prior art, the electrode handle clamping is unstable, which easily leads to electrode loosening and falling off. Moreover, the lack of limiting and guiding makes it easy for the electrode to deflect during insertion, making it difficult or impossible to insert into the handle.
A surgical electrode designed to prevent electrode drop includes an electrode and a handle. The clamping end of the electrode has a clamping groove circumferentially formed. The handle has a first positioning area, a second clamping area and a third clamping area. The electrode is guided and clamped step by step by a guide ramp. Metal clamping components and wall ribs are used for limiting the position to ensure stable installation of the electrode.
This design achieves stable clamping of the electrode within the handle, preventing the electrode from falling off, improving the accuracy and safety of installation, and reducing the risk of deflection during electrode insertion.
