Tissue effects of an ultrasonic scalpel for clinical surgical use.
The effects of a new ultrasonic scalpel were studied in laboratory animals. Tissue heat conduction from the tip of the ultrasonic blade was measured. Tissue damage was assessed by light microscopy of histochemically stained sections. The ultrasonic scalpel incised nonfibrous tissue effectively, with minimal heat conduction, and the incisions healed with no evidence of fibrosis nor of tissue destruction.
