The plasma scalpel.
The plasma scalpel simultaneously cuts tissue and cauterizes blood vessels measuring 3 mm in diameter with a small, hot (3000 C) gas jet. In animal studies, the amount of hemorrhage has been shown to be less with the plasma scalpel than with steel or electrosurgical scalpels, and incisions have healed without complications. Amount of damaged tissue is limited. Human trials are under way, and the device shows promise as a clinical tool.
