Abstract:
1. An apparatus for argon-plasma coagulation that is adapted to supply a working gas to a tissue that is to be treated, said apparatus comprising: a gas-supply device through which the working gas flows in a supply-flow direction and from which the working gas flows out at a distal end of the gas-supply device, the gas-supply device comprising a connector conduit, wherein a first end of the connector conduit is connected to an argon-plasma-coagulation instrument and a second end of the connector conduit is joined to a surgical instrument via an insert piece; an obstructor disposed in the insert piece, wherein the obstructor obstructs a flow of at least one of gas and liquid in the gas-supply device, against the supply-flow direction; and an actuation means disposed in the connector conduit, upstream of the obstructor relative to the supply-flow direction, wherein an open state of the obstructor can be achieved by the actuation means by joining together the surgical instrument and the connector conduit via the insert piece.
