Tungsten needle can be used as an electrode in a cosmetic electrotome - a kind of electrosurgical product for minimally invasive surgery. Generally, such a tungsten electrode is ultra-sharp with high temperature resistance so that the cosmetic electrotome can achieve precise cutting. And there is less smoke during operation, to protect the doctors.

According to reports, tungsten needles are gradually replacing stainless steel needles as electrodes for cosmetic electrotomes. Because the tungsten electrode can withstand high temperatures above 3400 °C, while the temperature resistance of stainless steel needle is only between 1300 °C and 1400 °C. Generally speaking, the tungsten needle electrode with high melting point can always maintain the sharpness during the large-scale and long-term surgery, and stainless steel needle is relatively easy to become dull during such major surgery, resulting in unsatisfactory surgical results. For example, the surgical wound is large, and it is not conducive to postoperative recovery.
