Coated Pencil， PlasmaBlade~? 3.0S and PlasmaBlade~? 4.0 for intraoperative tissue dissection using the fresh extirpated porcine muscle model

摘要

Penetrating thermal tissue damage/spread is an important aspect of many electrosurgical devices and correlates with effective tissue cutting, hemostasis, preservation of adjacent critical structures and tissue healing. This study compared the thermal damage/spread associated with the PhotonBlade~?, Valleylab~? Pencil， Valleylab~? EDGE~? Coated Pencil， PlasmaBlade? 3.OS and PlasmaBlade? 4.0， when performing a single pass dynamic tissue cut in fresh extirpated porcine longissimus muscle. These devices were used in a fashion that emulated their use in the clinical setting. Each device's thermal damage/spread, at Minimum, Median and Maximum power input settings, was assessed with nitroblue tetrazolium viability staining in the WVU Pathology Laboratory for Translational Medicine. The thermal damage/spread associated with the PhotonBlade? was compared with the other devices tested based on the individual treatment results (n=179 cuts combined). In summary, the PhotonBlade? overall demonstrated the least penetrating thermal tissue damage/spread, followed by the PlasmaBlade? 4.0, then Valleylab? Pencil and PlasmaBlade? 3.OS and then Valleylab? EDGE? Coated Pencil in order of increasing thermal damage/spread depths.
