Tungsten needle is often used as an ablation electrode, which is mainly made of 99.99% high purity tungsten, having the characteristics of high melting point and high temperature stability.

What is an ablation electrode? The ablation electrode is an accessory of high-frequency surgical equipment. It ablates, stanches, electrocuts, electrocoagulates, attracts, and peels off related tissues during surgery. It has been used to replace traditional scalpel and is widely used in surgery.
Why choose tungsten needles as ablation electrodes? Let’s begin with characteristics of tungsten electrode. The tip of tungsten electrode has different types such as a platform type, a tip type, or an arc type; the needle tip can be controlled to a minimum of 50 nanometers, the tip discharge is concentrated, and the tissue thermal damage area is smaller; the surface is mirror-finished, and the roughness is less than 0.25, which can effectively avoid tissue adhesion, and reduce skin tissue burns.
