摘要
A surgical instrument having a handle (21) at one end, a metal cauterizing element, e.g., a cutting blade (31), at the opposite end, and an electrical heater (4) for electrically heating the cauterizing element; the electrical heater including at least one positive temperature coefficient (PTC) heater which heats the cauterizing element and maintains a relatively constant temperature therein despite variations in the thermal load, such that the electrical power consumed by the surgical instrument automatically changes with changes in pressure applied to the cauterizing element.
