Abstract: A hemostasis instrument for actively stopping the bleeding, in particular after an open, laparoscopic, or endoscopic operation on a patient, having several hemostasis components. The hemostasis instrument has at least the following hemostasis components:—a thermal hemostasis device for tissue coagulation by producing a temperature above the coagulation temperature of biological tissue by means of a coagulation electrode;—a biochemical hemostasis device for producing a silent electric discharge by means of at least one discharge electrode, and an insulating device, wherein the insulating device is arranged between the discharge electrode and the tissue to be treated;—a supplying device for supplying substances that influence blood clotting to the tissue to be treated, and—a supply device for supplying noble gas to the tissue to be treated.

Abstract: An electrosurgical assembly is disclosed having an electrosurgical instrument, a detection device for detecting a predetermined constituent of the atmosphere in the region of a treatment site and a treatment unit, which can be connected to the instrument and a current generator for providing RF energy. The treatment unit includes a mechanism for influencing the treatment process depending on an output signal of the detection device.

Abstract: A multi-functional element suitable for performing at least two surgical/therapeutic interventions, for example, the injection and cutting of tissue, with an anti-carbonization device to prevent the carbonization of tissue upon plasma coagulation by way of a suitable surgical instrument, where the surgical instrument has a feed line for an oxidizing agent, a feed line for a gas and an electrode for generating a plasma. A gas oxidizing agent mixture for producing a gas oxidizing agent plasma is provided by the anti-carbonization device.

Abstract: An anti-carbonisation device (1) is proposed to prevent the carbonisation of tissue upon plasma coagulation by means of a suitable surgical instrument (3), wherein the surgical instrument (3) has a feed line for an oxidising agent (7), a feed line for a gas (5) and an electrode (9) for generation of a plasma, and wherein a gas-oxidising agent mixture for generation of a gas-oxidising agent plasma is provided by the anti-carbonisation device (1).
