20080243114 | Instrument For Plasma Coagulation - For the coagulation of tissue by plasma, instruments are known that comprise a tubular probe body through which inert gas is conducted and an ignition electrode within the lumen in the region of an outlet of the probe body. A current conductor is provided to supply a coagulation current to the ignition electrode. The ignition electrode is fixed to the probe body substantially in the middle, by means of fixing devices. The present invention provides an instrument for plasma coagulation wherein a fixing device for the ignition electrode comprises a piece of sheet metal, a wafer or similar flat body, which is fixed by its longitudinal edges to the tube wall so that it extends substantially diametrically across the lumen, and to which the ignition electrode is attached. | 10-02-2008 |
20090023990 | PROBE MANIPULATOR - A probe manipulator which has a grip device that can be held by a user in order to facilitate manipulation of a probe when the latter has been inserted into a channel of an endoscope. Connection devices are provided for releasably connecting the grip device to the probe in such a way that the probe may be rotated or displaced by rotation or displacement of the grip device. The connection device is connectable such that the probe need not be fed through the grip device, but that the grip device may be placed at any point along the length of the probe. | 01-22-2009 |
20090076504 | Four-position rocker switch for electrosurgical handpiece - A surgical apparatus includes an actuation unit disposed on a handle and a control unit providing at least three modes for controlling the electrical instrument. The actuation unit contains a switching rocker with an operating element, which is rotatable about a rocker axis that can be shifted perpendicular to the surface of the handle, so that starting from an initial position a first or second function position can be reached by forwards or backwards rotation about the rocker axis, and a third function position can be reached by pressing the operating element inward, two sensors being disposed on the operating element, one on the left and the other on the right side of the rocker axis, in such a way that by means of the sensors the function position selected by means of the switching rocker can be determined by the control unit. | 03-19-2009 |
20100151722 | CONNECTION CABLE - A connection cable which allows various high-frequency surgical instruments to be used with various high-frequency surgical devices. The connection cable includes a first connecting means designed for connection to a socket of the high-frequency surgical device and a second connecting means designed for connection to the high-frequency surgical instrument. A programmable memory is provided which is connected to contacts of the first connecting means and controls adjustment of the high-frequency surgical device. The adjustment of the high-frequency surgical instrument is controlled in accordance with stored data sets in order to adapt device settings to the particular high-frequency surgical instrument. | 06-17-2010 |
20100262139 | DEVICE FOR CONTACTLESS COMMUNICATION AND USE OF A MEMORY DEVICE - The invention relates to a device for contactless communication between a surgical apparatus and at least one surgical instrument. The surgical apparatus comprises a control and evaluation device to which is assigned a writing or reading device, which is connected to an antenna for the apparatus. The instrument is assigned at least one writable and readable memory device, embodied as an RFID transponder, which is connected to an antenna for the instrument, so that data can be exchanged between the writing or reading device of the surgical apparatus and the memory device of the instrument by means of wireless communication. | 10-14-2010 |
20120000756 | PUSH BUTTON, METHOD FOR THE PRODUCTION THEREOF, AND MEDICAL MANIPULATING PART - A push button of a medical manipulating part comprising: a first, pot-shaped, shell-shaped or box-shaped housing piece, at least some sections of which contain conductive material, with an integrally molded switching spring and a continuous wall, a second housing piece, the shape of which mates with the wall of the first housing piece and is inserted therein in a hermetically sealed manner such that a hollow space is formed between the first and second housing pieces underneath the switching spring and at least one mating contact for the switching spring, said mating contact being hermetically sealed and electrically isolated relative to the first housing piece, being led through the second housing piece and extending into the hollow space underneath the switching spring. | 01-05-2012 |
20120004649 | SWITCHING CONTROL DEVICE AND MANIPULATING PART FOR A MEDICAL INSTRUMENT - A switching control device for a medical instrument such as an electrode used in HF surgery. The switching control device comprises a connection line, designed as a switching control module for controlling various electrical operating modes of the instrument with a three-dimensionally and pressure-tightly sealed housing that is resistant to sterilization temperatures, an actuating element and fixing means to be releasably mounted within or on a manipulating part of the instrument, and module contacting means for interacting with device- or instrument-contacting means that are connected to the connection line to perform a switching control function. | 01-05-2012 |
20130274742 | APPARATUS FOR COAGULATING TISSUE - An apparatus for coagulating tissue, including a gas-delivering device for delivering a plasma comprised of an ionized inert gas from the outlet of the gas-delivering device, an electrode adapted to supply a high-frequency current that projects out of the gas-delivering device and a guiding device disposed at a distal end of the electrode. The relative configuration of the outlet of the gas-delivering device and the guiding device are such that the plasma (and an electric arc) can be directed in any direction 360° with respect to the outlet of the gas-delivering device. The plasma is directed along a path of least electric resistance, thus causing the plasma to be directed to a tissue to be treated, regardless of a position of the tissue relative to a rotational position of the outlet of the gas-delivering device. | 10-17-2013 |
