Abstract

An ultrasonically vibrating knife has been developed for producing surgical incisions with reduced hemorrhage. Tissue injury and wound healing of porcine cutaneous incisions produced by this instrument, conventional scalpel, electrosurgery, and CO2 laser were compared regarding clinical, histopathologic, and tensile strength differences. Scalpel incisions had the least tissue injury and fastest healing, but the ultrasonically vibrating knife produced less tissue injury and faster healing than electrosurgery or CO2 laser.
