PEAK Surgical Announces Positive Surgical Incision Wound Healing Results With the PEAK PlasmaBlade(TM)

allow for healing. Digital photos of the wounds were taken every seven days to evaluate scarring based on a visual analog scale. Histological examination was conducted to evaluate healing and inflammatory response.

Results showed that bleeding for 60 seconds following incision was reduced by 60 percent in the PEAK wounds compared with the standard scalpel wounds (p=0.0001). Wound sections showed greatly reduced acute thermal damage from the PEAK PlasmaBlade compared with the traditional electrosurgery scalpel (p=0.02). At six weeks, results showed minimal scarring of the PEAK and standard scalpel incisions compared with significant scarring of the traditional electrosurgery incisions (p=0.02 and 0.03, respectively). There was no significant difference in tissue injury between the PEAK and scalpel incisions, and both were significantly better than the traditional electrosurgery incision at one week (p=0.015).

"These study findings demonstrate that, compared with standard surgical techniques, pulsed plasma radiofrequency energy is clearly a superior method for efficient tissue dissection with superior hemostasis and minimal thermal damage," said Dr. Loh.

About PEAK's Technology

For decades, surgeons have relied on scalpels to cut skin and delicate tissues and on electrosurgical devices to cut and coagulate fat and other thicker, tougher tissues. Although scalpels precisely cut tissue with minimal injury, they do not control bleeding. Electrosurgical devices, on the other hand, cut efficiently and control bleeding but can cause thermal damage to surrounding tissue.

PEAK Surgical's flagship surgical system, the PULSAR(TM) Surgery System, combines the PULSAR Generator, which provides unique pulsed plasma radiofrequency waveforms, with the PEAK PlasmaBlade, a highly insulated tissue dissection instrument, to enable precise cutting with bleeding control and minimal thermal damage. This technology provides the benefits of both traditional scalp
