摘要
Method and means are disclosed for preventing tissue from adhering to surgical apparatus (e.g. a heated surgical scalpel) while operating at tissue temperatures (usually 100-500 DEG C) at which haemostasis with minimal tissue damage occurs, and include interposing between the surgical apparatus 11 and the tissue 13 being heated thereby a non-adherent coating 12 which has specific parameters including thermal impedance, thickness and thermal drop thereacross. The coating 12 may be of fluorocarbon polymers, silicones, metallic fluorides or organic phosphates, or may be a sacrificial solid or liquid layer of waxes, greases, oils or other fluorinated polymers or silicones.
