Abstract: The medical instrument includes a male instrument connector, which includes at least one male fluid connector arranged on a flat face. A venting bore may also be arranged on the same face and disposed to act as pressure relief by which leaking fluids that accumulate in the instrument can be discharged. A cover cap may be attached to the face. The cover cap allows for sterilization of the instrument, including the male instrument connector.

Abstract: An electrosurgical instrument including a probe tube for transporting fluid, at least one electrode for devitalizing tissue, and at least one conducting foil electrical lead arranged along the longitudinal axis of the probe tube for providing a high frequency (RF) voltage at the electrode. A method of producing an electrosurgical instrument, including applying a conductive foil to a probe tube that extends along the longitudinal axis of the probe tube, and providing at least one electrode on the probe tube, wherein the electrode electrically connects to the conductive foil.

Abstract: A tube connector for a radio-frequency surgical device, having two end sleeves, which are each provided with an axial through channel and connected to each other by a web extending from a wall plane of the first end sleeve axially in the direction of the second end sleeve. The web being at least partially made of an electrically conductive material, and the respective end sleeves can be compressed or crimped in some regions for fixing a tube, which can be arranged in the respective through channel. Also disclosed is a handle for an RF surgical device, and to a method for connecting tubes for an RF surgical device to such a tube connector.
