Less Damage Improves Healing and Clinical Outcomes

Since Bovie and Cushing used the first electrosurgical instruments in 1928, little has been done to reduce the collateral thermal damage inherent to this technology. Although thermal injury depth may vary with power setting, pass rate, electrode design, and tissue type, traditional electrosurgical instruments demonstrate average injury values of 500μm to 1.5mm deep to incised tissue. Comparatively, the PEAK PlasmaBlade™ surgical device demonstrates thermal injury values on
the order of 50μm to 250μm.

The postoperative benefits of low thermal technology are well known. Multiple human and animal clinical studies have demonstrated that a reduced thermal injury profile results in improved healing characteristics. Specific to the PEAK PlasmaBlade device, clinical research has demonstrated significant reduction in thermal injury depth, inflammatory response and healed scar width compared to traditional electrosurgery; and equivalence in healed incision strength, inflammatory cell counts and healed scar width compared to scalpel.1-3,*

When this reduction in thermal injury compared to traditional electrosurgery is applied over a large area – as with surgeries requiring extensive electrosurgical tissue dissection – use of the PEAK PlasmaBlade device has resulted in macroscopic postoperative benefits, such as patients reached 50% of normal diet by day 2 (median) vs. day 6.5 (median) for SOC (p = 0.0047).4,*

The PEAK PlasmaBlade uses less total energy and operates at significantly lower temperatures than traditional electrosurgical technology (40 – 170°C vs. 200 – 350°C).5,** The PEAK PlasmaBlade device provides surgeons with a novel alternative to traditional technology that eliminates the risk of scalpel injuries6 and has been shown to dissect 24% (p = 0.0002) more grams of tissue per minute than traditional electrosurgery, increasing surgical efficiency.7,*
