Abstract: An electrosurgical generator including housing and an internal circuitry to generate a high-frequency voltage and to output the generated high-frequency voltage to an electrosurgical instrument, further including at least one output socket for connection of a plug of the electrosurgical instrument. The output socket is configured as self-contained unit including: a casing configured for mounting at a front plate of the housing; a plug socket mounted at a frontal face of the casing for plugging of the electrosurgical instrument; a conductor board inserted into the casing and being configured to provide internal connections of the output socket; and a connector provided at the conductor board for a connection to the internal circuitry. Thereby the output socket is modularly exchangeable. Being self-contained, the output socket can be easily exchanged against another output socket of different functionality, allowing for easy re-configuration.

Abstract: Electrosurgical generator for providing a high-frequency alternating voltage to an electrosurgical instrument, including a control unit and an inverter for high voltage that generates a high-frequency alternating voltage fed to an output socket for the instrument. A detection unit is provided that includes a capacitive detector configured for detecting a capacitance of a plugged-in cable of the instrument. Thereby a parasitic capacitance induced by the instrument's cable can be detected. The capacitance is however low picofarad range and difficult to detect, further complicated by the requirement of galvanic separation for patient safety. However, the invention realized that just a qualitative detection is sufficient to determine whether the instrument's cable is being plugged in. The invention provides simple and efficient measurement circuit for such detection. Thereby, a safe and cost-effective plugging-in detection is realized.

Abstract: A catheter for the high-frequency therapy of body lumens has a flexible shaft tube of preferably biocompatible plastic material, which is connected to a distal end piece in the region of the distal end of the catheter. A proximal part of the distal end piece, that projects into the distal part of the shaft tube, forms a damping connection to the distal end of the shaft tube, which is secured by a distal electrode which is drawn on to the external peripheral surface of the shaft tube, by the distal electrode exerting a radially inwardly acting clamping force on the damping connection.

Abstract: The invention concerns a medical technology device for treatment of the human or animal body, comprising at least one electrical plug connector which is adapted to be connected to a complementary counterpart plug connector of a further medical technology device and which in an active position is arranged projecting upwardly at the top side of the device. To provide a medical technology device which can be used both as an individual device and also in conjunction with a second device as a device arrangement and which in that respect satisfies existing safety and aesthetic demands, it is provided in accordance with the invention that the plug connector is adapted to be movable from the active position into a passive position, wherein in the passive position the plug connector is removed from the top side of the device and the top side is closed in substantially fluid-tight relationship.

Abstract: The invention concerns an application device for electrosurgical cutting and coagulation of body tissue, wherein the instrument is in the form of a gripping instrument having two gripping arms which are movable relative to each other and which each have at their distal end at least two respective electrodes, namely at least one coagulation electrode and at least one cutting electrode.

Abstract: A catheter for the high-frequency therapy of body lumens has a flexible shaft tube (16) of preferably biocompatible plastic material, which is connected to a distal end portion in the region of the distal end of the catheter. A proximal part (14.p) of the distal end portion (14), that projects into the distal part of the shaft tube (16), forms a clamping connection to the distal end of the shaft tube (16), which is secured by a distal electrode (18) which is drawn on to the external peripheral surface of the shaft tube, by the distal electrode exerting a radially inwardly acting clamping force on the clamping connection.

Abstract: A solenoid valve is described, its armature having a part that is slidingly displaceable on the foundation bolt and is movable between two stops of the foundation bolt against the tension force of a restoring spring. When the armature strikes the valve seat of the solenoid valve, the slidingly displaceable part moves further under the influence of its inertial mass on the foundation bolt in the closing direction against the tension force of the restoring spring, until it strikes the second stop of the foundation bolt. The resulting transfer of momentum to the foundation bolt reduces impact of the armature on the valve seat and causes the armature to more quickly reach a defined rest position in which the solenoid valve is closed.
