  • Patent number: 9743916
    Abstract: A surgical positioning instrument for supporting and holding organs includes a preferably concave bearing portion and a supporting portion substantially rearward with respect to the bearing portion. Via the bearing portion an organ which is to be positioned can be received and via the supporting portion the surgical positioning instrument can be supported at an environment of the organ. Further, at least the bearing portion partly simulates a surface of the organ to be supported and is designed to be dimensionally stable.

  • Patent number: 9603655
    Abstract: An electrosurgical instrument includes a proximal end and a distal end having a jaw member assembly at the distal end including a first jaw member and a second jaw member movable relative thereto. The jaw members can be transferred relative to each other from an opening position into a gripping position in which they are arranged to be closer to each other than in the opening position. Each jaw member has at least one electrode connectable to an electric power source and electrodes of both jaw members being adapted to interact for sealing body tissue held between the jaw members in the gripping position, actuating means for transferring the jaw members from the opening position into the gripping position and means for limiting the closing width of the jaw members, when they are transferred from the opening position into the gripping position.

  • Patent number: 9468359
    Abstract: A control apparatus for use in endoscopes or the like is provided which allows a user to work without fatigue. The control apparatus includes a proximal and distal end sections, each of which has an articulation zone, and a central section arranged therebetween, an outer hollow-cylindrical shaft, an inner cylindrical shaft, and a control element arranged between the shafts and having two or more force-transmitting longitudinal elements extending substantially from the proximal to the distal end section for coupling movement of the distal end section with movement of the proximal articulation section. The longitudinal elements are arranged in spaced-apart relation to one another at substantially regular angular distances which, as measured in a circumferential direction, are selected such that the longitudinal elements are guided without contact in a circumferential direction and optionally guided in contact with the outer and/or the inner shaft in a radial direction.

  • Publication number: 20140303664
    Abstract: The present application relates to an atraumatic sternal plate for haemostasis for a retractor with a pressure plate and a retaining device attached to the pressure plate. The pressure plate can be attached, by means of the retaining device, to either the blades of a retractor or to a sternal half of the patient, so that the pressure plate abuts the sagittal incision surface of a sternal half when spreading the sternum of a patient by means of a retractor.

  • Patent number: 8353898
    Abstract: A surgical instrument is provided, comprising proximal and distal end sections each comprising an area of articulation, as well as a flexurally rigid central section arranged therebetween. The proximal end section can be connected to an actuating device. A tool which can be driven by means of a drive element can be connected to the distal end section. To provide greater flexibility and a greater working area, the instrument further comprises outer and inner hollow cylindrical shafts and a control element which is arranged between the shafts. Two or more longitudinal elements extend at least substantially from the proximal to the distal area of articulation of the instrument and transfer traction and/or pressure forces. The longitudinal elements are arranged at essentially regular angular distances in a circumferential direction of the instrument and are connected to one another in the circumferential direction at their proximal and distal ends.
