<p>The present invention pertains to the field of medical techniques and relates to surgical instruments for carrying out dissection and coagulation operations on tissues. The present invention enables the dissection of tissues while simultaneously coagulating the same. The method involves using a dissection and coagulation apparatus in the form of a gas-vapour generator which can be realised separately or associated with a surgical instrument, mainly a cutting device of the endoscopic-scissors type or an unipolar electrode. The gas-vapour generator is used for accurately supplying a high-temperature vapour or gas-vapour flow towards the tissues in order to carry out a dissection and a coagulation, wherein said flow is sufficient for breaking and laminating the tissues. The generator includes a body comprising a reaction chamber in which a gas-vapour mixture is formed from a substrate capable of rapid transition from a liquid phase to a vaporous or gaseous phase. The generator also includes a heating device as well as a small outlet opening or several openings or a directed nozzle.</p> |
