Claims (7)

1. Als Instrumentenkanal für die Minimal Invasive Chirurgie dienende rohrförmige Hülse mit variablem Innendurchmesser, dadurch gekennzeichnet, dass die Hülse 4 am proximalen Ende in einem hohlen Adaptionselement 1 befestigt ist und sich nach distal durch Faltung der Wand in der Längsachse im Durchmesser verjüngt und in diesem Durchmesser nach proximal ausläuft, wobei die Hülse mit Hilfe eines Dilatationstrokares zu einem größeren Durchmesser entfaltet werden kann.1. As an instrument channel for minimally invasive surgery serving tubular sleeve with variable inner diameter, characterized in that the sleeve 4 is fastened at the proximal end in a hollow adaptation element 1 and tapers in diameter distally by folding the wall in the longitudinal axis and in this Diameter runs out proximally, and the sleeve can be expanded to a larger diameter with the aid of a dilatation trocar. 2. Instrumentenhülse nach Anspruch 1, dadurch gekennzeichnet, dass im Adaptionselement 1 Dichtungselemente integriert sind, welche das Lumen der Hülse gegen die proximale Öffnung des Adaptionselementes abdichten.2. Instrument sleeve according to claim 1, characterized characterized in that in the adaptation element 1 Sealing elements are integrated which cover the lumen the sleeve against the proximal opening of the Seal the adaptation element. 3. Instrumentenhülse nach Anspruch 1, dadurch gekennzeichnet, dass das distale Ende der Hülse auf einer kurzen Strecke von wenigen Millimetern lediglich den Durchmesser der Veressnadel besitzt und keine Faltung der Wand aufweist und gegebenenfalls sogar konisch geformt ist, um einen Übergang zur Mantelfläche der Veressnadel mit möglicht geringem Kalibersprung zu erhalten, und somit keine den Operationsablauf behinderte Stufenbildung in der Penetrationsdruckkurve zu erhalten. Dieses distale Ende besitzt eine Sollbruchstelle im Längsverlauf, welche bei der Dehnung aufreisst.3. Instrument sleeve according to claim 1, characterized characterized in that the distal end of the sleeve is on a short distance of a few millimeters only has the diameter of the Veressnadel and has no fold in the wall and if necessary is even tapered to transition to Shell surface of the Veressnadel with as little as possible To get caliber jump, and therefore not the Operation sequence disabled stage formation in the Obtain penetration pressure curve. This distal  The end has a predetermined breaking point along its length, which tears open when stretching. 4. Instrumentenhülse nach Anspruch 1, 2 oder 3 dadurch gekennzeichnet, dass am Adaptionselement ein Zuführungskanal mit Ventil für CO2-Gas angebracht ist, welcher die Zuführung von CO2-Gas in das Adaptionselement, beziehungsweise die Hülse distal der Dichtungselemente erlaubt.4. Instrument sleeve according to claim 1, 2 or 3 thereby characterized in that at the adaptation element Supply duct with valve for CO2 gas attached which is the supply of CO2 gas into the Adaptation element, or the sleeve distally the sealing elements allowed. 5. Instrumentenhülse durch einen zweiteiligen Aufbau gekennzeichnet, wobei mit der Veressnadel zunächst eine C-förmige nicht gefaltete Hülse welche die Veressnadel eng umschließt und distal in ein Adaptionselement mit größerem Durchmesser endet eingebracht wird. Nach dem Primäreinstich wird die Veressnadel entfernt und eine Instrumentenhülse nach Anspruch 1, 2, 3 oder 4, welche sehr platzsparend in der Längsachse gefaltet werden kann, in die C-Hülse eingeschoben und dann aufgedehnt, wobei die C-Hülse lediglich aufklappt und am Operationsende zusammen mit der Instrumentenhülse gegebenenfalls durch ineinandergreifen der beiden Adaptionselemente entfernt wird.5. Instrument sleeve through a two-part construction characterized, with the Veressnadel first a C-shaped unfolded sleeve which the Veressneadel tightly and distally in one Adaptation element with a larger diameter ends is introduced. After the primary puncture, the Removal needle and an instrument sleeve after Claim 1, 2, 3 or 4, which is very space-saving the longitudinal axis can be folded into the C-sleeve inserted and then stretched, taking the C-sleeve just unfold and together at the end of the operation with the instrument sleeve if necessary interlocking of the two adaptation elements Will get removed. 6. Instrumentenhülse nach einem oder mehreren vorgenannten Ansprüchen, dadurch gekennzeichnet, dass die Wand der Hülse in der Längsrichtung zur Durchmesserverringerung gefaltet ist und in einer vorteilhaften Ausführungsform bei definierter Faltung der Hülse die nicht Mantelaußenfläche bildenden Hülsenabschnitte zum Beispiel den Außendurchmesser lokal vergrößernde Formelemente in Querrichtung besitzen, welche erst nach der Entfaltung an die Mantelaussenfläche gelangen und eine Fixation der Hülse im Gewebe in der Längsrichtung bewirken. Nach Entfernung der Trokarhülse, wird die Instrumentenhülse wieder durch den Druck des umliegenden Gewebes zusammengefaltet und die Formelemente sind dann nicht mehr auf der Mantelaußenfläche. So kann die Instrumentenhülse im zusammengefalteten Zustand dann wieder leicht entfernt werden.6. Instrument sleeve after one or more aforementioned claims, characterized in that the wall of the sleeve in the longitudinal direction Diameter reduction is folded and in one  advantageous embodiment with defined folding the sleeve does not form the outer surface of the jacket Sleeve sections, for example, the outer diameter locally enlarging elements in the transverse direction own, which only after the unfolding to the Outer surface and a fixation of the Create a sleeve in the tissue in the longitudinal direction. To Removal of the trocar sleeve, the Instrument sleeve again by the pressure of the surrounding tissue folded and the Form elements are then no longer on the Outer shell surface. So the instrument sleeve in the then folded again easily be removed. 7. Hülse nach einem oder mehreren der oberen Ansprüche dadurch gekennzeichnet, dass das Adaptionselement reversibel an eine entsprechende Veressnadel adaptiert werden kann.7. sleeve according to one or more of the above claims characterized in that the adaptation element reversible to a corresponding Veressnadel can be adapted.
