Multifunctional instrument and method for preventing the carbonization of tissue by means of a multifunctional instrument

摘要

Multifunctional instrument (13), which is designed for injecting, cutting and coagulating tissue, comprising: - an electrode (23) for generating a plasma, - an oxidizing agent supply channel (21) and - a gas supply channel (19), the oxidizing agent supply channel ( 21) and the gas supply channel (19) form a carbonization prevention device (15) which provides a gas-oxidizing agent mixture for generating a gas-oxidizing agent plasma at the place of coagulation, the oxidizing agent supply channel (21) as a liquid applicator for supplying an injection liquid to the Tissue and is designed for injecting the same, and wherein the injection liquid serves at the same time as an oxidizing agent.
