  • the suction cannula is designed so that it has several evenly distributed on the circumference suction holes.
  • Such a liposuction device is now known from US Pat. No. 5,968,008, which is equipped with an injection line arranged inside the suction cannula.
  • the injection line opens into an outlet bore from which a round jet of liquid emerges.
  • the two working steps of the injection of working fluid and the suction of fatty tissue with the working fluid are temporally superimposed, whereby the surgical procedure is time-saving and continuous.
  • WO 01/91827 Al a similar liposuction device is now described, the injection line terminates in a flattened acceleration nozzle with a slot-like outlet opening.
  • the slot-shaped outlet opening is straight or curved and aligned at an angle to the axis of the injection line.
  • the liquid jet is fan-shaped and exits at an angle to the axis of the injection line.
  • This fan-like liquid jet is intended to distribute the working fluid better in order to allow a uniform removal of a larger volume of fatty tissue.
  • the extracted fatty tissue cells are then no longer suitable for further use, since the fatty tissue cells are destroyed by the suction process and by the destructive influence of the working fluid.
  • a surgical device for removing tissue cells from a biological structure was described for the first time, which is primarily designed to completely separate the superfluous fat cells with the aid of a pressurized fluid jet from the adjacent tissue cells.
  • the outlet opening of the injection line is designed so that a flat jet is formed with a front cutting edge, which works like a scraper and thus achieves a peeling effect on the adipose tissue cells.
  • the liquid is chemically neutral and is under such a pressure which, in interaction with the smooth and soft adipose tissue cells, intrudes intelligently between adjacent tissue cells and forces them apart, mechanically separating the fixed tendons and tissue-cell-containing tendons, without destroy the Geweb ⁇ cells.
  • tissue cells thus separated in a gentle manner are sucked off together with the neutral liquid with a relatively low suction force and disposed of or separated again from the neutral liquid and reused.
  • the particular advantage of this surgical device is that the fatty tissue cells are separated solely by the force of the separating jet and the suction of the adipose tissue cells is carried out together with the neutral fluid by the force of the suction flow.

  • this surgical removal device "physical stress still occurs and even a certain proportion of fatty tissue cells is damaged.
  • WO 2004/014460 A2 has therefore proposed a novel nozzle shape which generates an angled liquid jet which forms a separating tip and two downstream separating edges.
  • This surgical device is very suitable for the removal of adipose tissue cells.
  • the invention is therefore based on the object of increasing the separation force of a generic surgical separation device and designing it to remove connective tissue.
  • the particular advantage of the new device lies in the broadening of the application. With this new device, it is also possible to remove fatty tissue cells in a known manner with the aid of a liquid separation beam. In addition, however, it is now also possible to remove those types of tissue which hitherto could only be removed by a mechanical separating tool. As for both Oewebeart now the same surgical tool is used, simplifies the device cost and also the surgical procedure is rational. When using the new surgical device for difficultly separable Geweb ⁇ arien, as it is, for example, the connective tissue, the liquid separation and the mechanical separation are combined. The benefits of liquid separation are exploited during mechanical separation. Thus, the liquid jet always seeks the spaces between adjacent tissue cells in a known manner and presses them apart.
  • the liquid jet seeking its own path aligns the tip of the curette with its parting and scraping edge on the connection points of the tissue cells, so that they can not act on the tissue cells themselves.
  • the tissue cells remain undamaged even during mechanical processing, which is extremely gentle for the patient.
  • the quality of the mechanical Trennvorgan ⁇ ges improved compared to the conventional mechanical separation of Gewe ⁇ participate, because now the tissue fibers to be cut through the expansion of the interstices of the tissue cells are streamlined and thus easier to cut.
  • the tissue parts separated in relatively large format are comminuted into smaller pieces of tissue immediately after separation by the liquid jet obtained and bundled in the groove of the curette. This avoids blockages at the suction in the intake manifold and simplifies the entire suction. So only a suction with a reduced suction pressure is required, which again gently affects the patient. It is expedient if the groove in the curette is formed as a half-shell, because thus the bundled liquid jet experiences a stable and sufficient support to maintain its bundled shape.
  • the Suction holes have a slot shape and the row of suction holes drallförraig runs.
  • tissue parts are excavated in such size as they fit through the suction holes. This avoids blockages during the suction process.
  • the elongated hole shape of the suction holes also reduces the risk of blockage, because this slot shape is largely matched to the shape of the fabric parts. Furthermore, it has been shown that the forming suction currentzigörmig runs.
  • the suction holes are aligned in a row swirl-shaped, in order to bring the smallest possible resistance to the tissue parts immersed in the suction holes. It is also expedient to either let the cutting edge of the curette tip taper out or to align it at right angles to the axis of the suction tube and / or to execute it with a relief grinding.
