  • Patent number: 11234579
    Abstract: A resectoscope has an elongated shaft tube, an elongated optic arranged therein with a lens at the distal end and an electrode assembly, wherein the electrode assembly in turn includes an electrode arranged at the distal end of the arms of a fork assembly, which are arranged on opposing sides of the lens and are brought together in a transition region to an electrode shaft, wherein the electrode assembly can be extended in the longitudinal direction by a stroke length from a first position, in which the electrode is arranged inside the shaft tube in front of the lens, into a second position in which the arms of the fork assembly protrude out of the shaft tube. The length of the arms of the fork assembly is thereby greater than 1.2 times the stroke length. The electrode assembly is configured correspondingly.

  • Publication number: 20220024662
    Abstract: After their production, components for surgical handheld devices are packaged in a packaging for the purposes of transport, storage or sterilization. In order that the component is fixed in a receiving space of the packaging, said component is retained by an insert. In addition, a cover which is releasably connected to the packaging body is located above the insert and the receiving space. When the cover is being separated from the packaging body, the insert may fall out in an uncontrolled manner. The invention provides a packaging for a component, said packaging being able to be handled in a simple and safe manner. This is achieved in that at least one insert for fixing a component in a packaging body is connected to a cover of the packaging.

  • Publication number: 20220015607
    Abstract: A surgical handheld devices are essentially made up of a device body or main body and of a tubular shaft. In the production of known surgical devices, the tubular shafts are welded to the device bodies. A large number of very complex work steps are necessary for this purpose. On account of the high quality demands placed on surgical handheld devices in respect of mechanical stability and sterility, the weld seam has to meet the most stringent requirements. The invention makes available a method for producing a surgical handheld device, which can be used particularly easily and reliably. This is achieved by the fact that at least one device body and at least one tubular shaft of a surgical handheld device are connected to each other with form-fit engagement by hydroforming.

  • Patent number: 11185365
    Abstract: High-frequency (HF) tools are used in medicine for manipulating body tissue, using an HF resectoscope. For electrical insulation of an electrode from an electrode support, the ends of the electrode are initially guided through ceramic tubes. These ceramic tubes are sensitive in particular to forces transverse to the longitudinal axis of the resectoscope. Disclosed herein is a high-frequency tool that has increased stability with respect to transverse forces. An electrode has two ends, which for establishing a connection to an electrode support are each insertable into a receiving opening of the ends of the electrode support, or positionable in front of the ends. The electrode is contacted in an electrically conductive manner, at least in the area of a receiving opening, with a conductor wire that is guided in the electrode support.

  • Publication number: 20180344382
    Abstract: The electrode head includes two working surfaces in accordance with an actual bipolar electrode. These may be manufactured lithographically, exhibiting even more complicated outlines. Working surfaces are depicted, which are structured as annulus sector-shaped, concentrically arranged areas, when projected in a plane. Moreover, a further area is situated centrally, which is disc-shaped in a planar projection. Plasma is ignited alternately at both poles. If the individual concentric zones are situated close enough with respect to each other a continuous plasma layer will result.
