PEAK Surgical, Inc. from Palo Alto, CA hates the bovie cutter/coagulator. The company cannot stand the 1920’s technology behind the bovie, and how its thermal function destroys healthy patient tissue around the cut. What do we hate about the bovie? Well, you know: all those bovie induced burns and destroyed gloves that surgeons are regularly subjected to.
Long story short, PEAK Surgical wants its Peak PlasmaBlade, a cold cutter and coagulator, to be the bovie of the 21st century. The company is quite hopeful: a new study presented in a poster session at the ongoing American College of Obstetricians and Gynecologists’ (ACOG) 56th Annual Clinical Meeting in New Orleans showed that PEAK PlasmaBlade™ “cut freshly excised human abdominal tissue with little thermal tissue injury compared with traditional electrosurgery.”
More about the technology:
Electrosurgery was invented in the beginning of the 20th century and became one of the most-often used surgical tools after William Bovie introduced his electrosurgery (radiofrequency) generator in 1926. Since then, electrosurgical cutting has been performed using continuous radiofrequency waveforms, which thermally vaporizes soft tissue via an electrical arc through air and Joule heating. This results in a cutting and coagulation action that leaves a wide zone of collateral thermal damage.
By contrast, PEAK Surgical’s PULSAR Generator supplies pulsed waveforms that produce short plasma-mediated, highly controlled electrical discharges through extensively insulated electrodes on a handheld device — the PEAK PlasmaBlade. 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.
PEAK Surgical’s technology including the pulsed plasma-mediated discharges and electrode insulation techniques were originally developed by Professor Daniel Palanker’s group at the Hansen Experimental Physics Laboratory and Department of Ophthalmology at Stanford University. They have been evaluated in ophthalmic applications, including human studies in retinal and cataract surgery – one of the most delicate, precise and difficult types of surgery, and in preclinical studies.
