Abstract

The invention concerns a device to improve the coagulation of moderately or heavily bleeding live human and animal tissue and to form an eschar by means of a plasma jet. The device comprises plasma-generating means consisting of an electrically conductive body (6) which is connected to a positive pole of a basic energy source having a positive potential. The body (6) is formed with a cylindrical channel (17) designed to heat the plasma-generating gas. The channel (17) is formed from a number of sections (8, 9, 10) which are electrically insulated from each other and each one of which is connected to the body (6) via bushes (22). The bushes are concentric with the sections (8, 9, 10) and are electrically insulating. The bushes (22) are formed with channels (19) arranged to conduct cooling liquid to and from the gas-heating channel (17).
