Peak Surgical has launched its PlasmaBlade, and this ain’t no plasma knife that you watch in the movies and read about in the comics. Instead, it is a cold cutter and a coagulator which has the ability to “cut freshly excised human abdominal tissue with little thermal tissue injury compared with traditional electrosurgery”. Here’s an excerpt about the technology.
Because the radiofrequency is provided in short pulses with low duty cycle (fraction of time the voltage is ON), and the PEAK PlasmaBlade is so highly insulated, heat diffusion and associated thermal damage to surrounding tissues is limited, resulting in greatly reduced collateral damage and extreme cutting precision.
In short, it cuts pretty much like adamantium – like a hot knife through butter, according to Logan, without causing much damage to the surrounding tissue.
