Abstract: A cervical punch has a hollow cylindrical circular morcellator tube, which is provided with a cutting region having an all-round wave grinding pattern around the distal opening. The morcellator tube, which can also be referred to as the basic body, receives a guide rod along which is possible an axial and/or rotary movement of the morcellator tube in a direct or indirect manner by a guide cylinder.

Abstract: The invention relates to a mechanical adhesion prophylaxis for endoscopy, in which a double-walled sheet is rolled onto a sheet applicator and introduced into the body cavity. In the body cavity the double-walled sheet is inflated in the manner of an air cushion and consequently prevents postoperative adhesion of deperitonized areas. The air cushion-like adhesion prophylaxis can be fixed in the body cavity by fixing areas.

Abstract: The invention relates to a heating apparatus, which, in conjunction with insufflators for introducing gas into a biological body, for avoiding catarrh to the peritoneum, pleura, etc., heats the greatly pressure-reduced gas to a temperature roughly corresponding to the body temperature. Use is made of a heating hose provided with a heating wire coil.

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.

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.

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.

Abstract: Apparatus for the insufflation of gas, particularly carbon dioxide, into the human or animal body, by means of which the gas is passed from a pressurized gas reservoir, preferably via one or more intermediate reservoirs and at least one pressure reducer, into a line and an insufflator, e.g. a Veress needle, the intraabdominal static pressure being measured by means of the apparatus. A gas flow regulator is positioned in the line between the pressure reducer and the insufflator. Downstream of the flow regulator is positioned a pressure gauge, whose measured value is fed as a function of time into an electronic evaluation circuit and is converted into the intraabdominal pressure.

Abstract: The present invention relates to an apparatus and method for insufflating fluid media into a cavity of a human or animal body, particularly the abdonimal cavity. A single hollow needle is utilized for intermittently insufflating the gas into the body cavity. Thereafter the flow of gas is interrupted and then the needle is connected with a pressure measuring device to determine both the static and dynamic fluid pressure of the body cavity. The amount of fluid insufflated can also be measured with the aid of the same hollow needle. Using the needle for insufflating will insure that the measuring will be correct since the gas during insufflating will blow any blood clots and/or tissue into the body cavity. The conduit leading to the needle may be split in a number of branches to insufflate gas at desired different pressures and/or volumes which again are variable. Most of the operation can be effected automatically. A display panel giving a visual indication of the parameters can also be provided.

Abstract: The disclosure is directed to a device for coagulating biological tissue by applying heat to the same. The device has a cooling arrangement by means of which the heating leading end portion which contacts and coagulates the tissue, can be cooled upon completion of the coagulation so that it can be safely withdrawn without causing damage to non-coagulated tissue which it may contact during the withdrawal.

Abstract: A method and a device for causing blood coagulation are disclosed. Both are especially well suited for use in endoscopy. A support is provided with an end portion on which an electrically operated thermo-element is located which receives electrical current to be heated to a level at which it has a coagulation-causing temperature. A control arrangement maintains the temperature steady when the level is reached. A visual indicator visually shows the heating of the thermo-element to the aforementioned level and an audible indicator audibly indicates the heating of the thermo-element by producing a sound which increases in intensity until the aforementioned temperature level is reached and which thereafter continues at a constant intensity while the temperature is maintained at the aforementioned level.
