Tungsten needle is a consumable of high frequency electric knife. Tungsten needle has an ultra-sharp needle point for precise cutting. Also, it has high melting point to withstand high temperatures above 3000 °C. So, such an electric knife is suitable for plastic surgery, neurosurgery, oral surgery, pediatric surgery, cardiothoracic surgery, and many other minimally invasive surgery. And the patients will recover relatively quickly as surgical wound is small.

How to prepare tungsten needle? You should prepare the following materials at first:

How to prepare tungsten needle by electrolytic method? The following materials are needed:

Ultrathin tungsten needle has advantages of high hardness and strong ductility. Also, it is not easy to break with durability. The diameter of tip of tungsten needle can reach micron level, which can be used to dissect and separate individual human cells, such as inner ear labyrinth cells. Some experts use 0.32mm tungsten wire to prepare ultrathin tungsten needles. They pre-machined the tips of fine tungsten wire blanks into needle-shaped, sickle-shaped, or hook-shaped needles. The diameter of the tip of these tungsten needles is generally 3 to 10 μm, and the smallest diameter can reach 1.5 μm.
