  • Publication number: 20080065063
    Abstract: A high-frequency (hf) endoscopic instrument (1) through which runs a metal stem tube (3) enclosing an operative conduit (10), fitted with a longitudinally displaceable electrode (13) supported in the operative conduit (10) and connected by an electric lead (14) crossing said operative conduit (10) to one of the two terminals of an hf generator (18). The metal stem tube (3) is connected to the other terminal of the generator (18) and in that the distal end zone of the operative conduit (10) is enveloped by an insulating tube (19) projecting beyond the distal end of the operative conduit (10) by a distance which corresponds to the safety separation (20) between the terminals in an electrically conductive liquid.

  • Patent number: 7258691
    Abstract: A working instrument for use in a resectoscope with a pushing force-transmitting elongated support, whose proximal end area includes an attachment section for attachment in a resectoscope, and whose distal end area carries a working device. The working instrument includes, in its distal end area, a handle element. The handle element projects in a distal direction beyond the support and the working device and is connected to the working instrument so as to transmit pushing forces and can be removed.

  • Patent number: 6755826
    Abstract: A urological resectoscope having an outer stem fitted with orifices at its distal terminal zone and an inner stem, both stems being tubular and metallic and being sealed from each other in the distal end zone and being affixed to each other, optionally in detachable manner, and to a main case. The resectoscope also includes an electrode support running longitudinally through the inner stem and bearing an hf-loaded cutting loop at its distal end. Liquid hookups feed liquid into the inner stem and drain liquid from an annular duct defined between the inner and outer stems. A distally affixed tubular insulating shell is disposed between the inner and outer stems and affixed to the outer stem.

  • Patent number: 6746395
    Abstract: A urological resectoscope having an axially extending shaft tube, the proximal end thereof being fixed to a main body. A sliding body is proximally positioned in relation to the main body, and can slide in a parallel manner in relation to the axis thereof. The sliding body includes a receiver, a fixing device and a contacting device. An electrode which can be subjected to a high frequency, including an electrode carrier having one external, insulated conductive wire, can be positioned in the resectoscope such that it can axially slide beyond the distal end of the shaft tube. In the assembly position, the electrode carrier extends through the shaft tube and the main body into the receiver, and can be fixed thereto by the fixing device and contacted therein by the contacting device.

  • Patent number: 6709386
    Abstract: An endoscope fill bar including a device to change the cross-section of a rounded end zone of the fill bar that protects distally beyond the endoscope distal end when the fill bar is in its functional position. The cross-sectional altering device is driven by an adjusting system mounted on the fill bar and through an adjustment link, and includes a lever resting at the distal end zone in a spreading-out and retracting manner.
