  • Patent number: 5350387
    Abstract: An instrument for the application of an adhesion prophylaxis, particularly a film for endoscopic surgery, includes a circular cylindrical application sleeve for insertion in a trocar cannula or for direct insertion in a pneumoperitoneum. The application sleeve can receive a rod-like film carrier onto which is wound the film-like adhesion prophylaxis. For this purpose an elongated, particularly axial reception area, such as a slot is provided in the front area of the sleeve in which the adhesion prophylaxis is received in interlocking or frictional manner.

  • Patent number: 5201739
    Abstract: The present invention relates to a medical instrument. Since, in the case of instruments operated by gripping disks, a conventional spring preloading has not been adequate for an effective closing movement, an improvement is proposed here. This consists of so articulating a front gripping disk to an instrument member that, through a manually applied axially rearward movement of the gripping disk, the instrument members are closed.

  • Patent number: 4909782
    Abstract: A tissue punch for removing tissue parts from the human or animal body is described, which comprises the actual operating instrument, as well as a separate driving unit, which is connected by means of a flexible force transmission member to the operating instrument. The operating instrument comprises a surgeon-guided outer tube and an inner tube slidably arranged therein having a cutting edge for separating the tissue parts. The inner tube is also supplied with a vacuum by means of a hose connection for removing a separated tissue part from said inner tube. The operation of the inner tube or the cutting edge connected thereto, as well as the suction are controlled by a separate control unit.

  • Patent number: 4830002
    Abstract: A relatively flat, disk-shaped gripping device for a medical instrument is moved axially with respect to the instrument by exerting pressure by the hand, or in a circumferential or rotary direction by the finger or thumb. The gripping device is fixed in non-rotary manner on the distal side of the shaft of a medical instrument, allowing a surgeon to easily place the instrument into any random rotary position by finger actuation, without adjusting the basic position of the hand.
