Abstract
The description relates to an endoscopic cutting device for separating tissue, e.g. organs, parts thereof or the like, with a cutting tool fitted at the distal end of the cutting device and having a cutting blade and with an operating unit for using the cutting device, fitted at the proximal end of the device. The feature of the device of the invention is that the cutting blade is fitted approximately parallel to a longitudinal unit of variable length.
Claims
1. Endoskopische Schneidvorrichtung zum Abtrennen von Gewebe, wie Organen, Organteilen oder dgl. , mit einem Schneidwerkzeug, das am distalen Ende der Schneidvorrichtung angebracht ist, und das eine Schneidklinge aufweist, die in etwa parallel zu einer Längseinheit angeordnet ist, die in ihrer Länge variierbar ist, und einer Betätigungseinheit, die zum Bedienen des Schneidwerkzeugs dient und die am proximalen Ende der Vorrichtung angebracht ist, dadurch gekennzeichnet, daß die Schneidklinge (4) gerad¬ linig ausgebildet ist, daß die Längseinheit zwei elastische Bänder (6) aufweist, die beidseitig der Schneidklinge angeordnet sind, und daß die Bänder distalseitig fest an der Vorrichtung und proximalseitig an einer mit der Betätigungseinheit (9) verbundenen Schubstange (5) angebracht sind, so daß sie durch eine Bedienung der Betätigungseinheit in ihrer Länge variierbar sind, wobei die Bänder im gelockerten Zustand die Bänder über der Schneid¬ klinge eine Bucht bilden, die über das abzutrennende Organ oder Organteil gelegt werden kann, und im gestrafften Zustand Bänder unterhalb und parallel zur Schneidklinge verlaufen, so daß das abzutrennende Gewebe gegen die Schneidklinge gedrückt und abgetrennt wird. An endoscopic cutting device for severing tissue, such as organs, organ parts or the like, with a cutting tool attached to the distal end of the cutting device and having a cutting blade that is approximately parallel to a longitudinal unit disposed in its length is variable, and an actuating unit which serves to operate the cutting tool and which is attached to the proximal end of the device, characterized in that the cutting blade (4) gerad¬ is linear, that the longitudinal unit comprises two elastic bands (6) are arranged on both sides of the cutting blade, and that the bands are fixed distally on the device and on the proximal side to a with the operating unit (9) connected push rod (5), so that they are variable by an operation of the actuator unit in length, wherein the bands when loosened, the bands above the cutting blade form a cove, i e can be placed over the organ or organ part to be separated, and run in the tightened state bands below and parallel to the cutting blade, so that the tissue to be separated is pressed against the cutting blade and separated.

2. Schneidvorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Schneidklinge in Längs¬ richtung mittels einer Betätigungseinrichtung (9) bewegbar ist.2. Cutting device according to claim 1, characterized in that the cutting blade in the longitudinal direction by means of an actuating device (9) is movable.
3. Schneidvorrichtung nach einem der Ansprüche 1 oder 2, dadurch gekennzeichnet, daß die Längseinheit aus einem Material mit shape-memory-Effekt besteht.3. Cutting device according to one of claims 1 or 2, characterized in that the longitudinal unit consists of a material having a shape-memory effect.
4. Schneidvorrichtung nach Anspruch 3, dadurch gekennzeichnet, daß die Längseinheit aus einer Nickel-Titan-Legierung besteht und eine Bandform mit einer rechteckigen Querschnittsgröße von 2 x 0.7 mm aufweist.4. Cutting device according to claim 3, characterized in that the longitudinal unit consists of a nickel-titanium alloy and has a band shape with a rectangular cross-sectional size of 2 x 0.7 mm.
5. Schneidvorrichtung nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, daß die Schneidklinge während des Straffens der Längseinheit gegen das abzutrennende Organ oder Organteil bewegbar ist. 5. Cutting device according to one of claims 1 to 4, characterized in that the cutting blade during the tightening of the longitudinal unit is movable against the organ or organ part to be separated.
