Description

Chirurgisches SchneidwerkzeugSurgical cutting tool

ErfindungsbeschreibungDescription of the invention

Gegenstand der Erfindung ist ein chirurgisches Schneidwerkzeug zum Entfernen verschiedener pathalogischer und anderer Gewebeteile wie z.B. Knochen, Knorpel, Narben u.s.w.The subject of the invention is a surgical cutting tool for removing various pathological and other tissue parts such as bones, cartilage, scars, etc.

Bekannt sind chirurgische Schneidinstrurnente wie die Modelle der Nr. FF720 - FF723 gemäß des Kataloges der Firma „ÄSKULAP" aus dem Jahre 1973 und der Patentschrift DE 195 01 258 A1. Die Nachteile dieser Instrumente bestehen in Ihrer Schwergängigkeit, sowie der Schwierigkeit bei der Entfernung der Schneidreste, der mangelnden Schneidgenauigkeit, und dem Risiko einer Rissbildung in dem verbliebenen Knochen durch die höhere Druckbelastung, ebenso einer geringeren Lennsdauer durch zu schnellem Verschleiß. Ais Nachteile der bekannten Schneidwerkzeuge beim Entfernen von weichem Gewebe sind das Einklemmen statt Schneiden zu bezeichnen.Surgical cutting instruments such as models FF720 - FF723 are known according to the "ÄSKULAP" company catalog from 1973 and the patent DE 195 01 258 A1. The disadvantages of these instruments are their stiffness, the difficulty in removing the cutting residues, the lack of cutting precision, and the risk of cracks in the remaining bone due to the higher pressure load, as well as a shorter service life due to too rapid wear. The disadvantages of the known cutting tools when removing soft tissue are the fact that they pinch instead of cut.

Ausgehend von dem obigen Stand der Technik liegt der Erfindung zu Grunde , die Schaffung eines Schneidwerkzeuges welche die o.g. Nachteile ausschließt.Based on the above prior art, the invention is based on the creation of a cutting tool which eliminates the above-mentioned disadvantages.

Die Konstruktion wird in Fig. 1 dargestellt. Schneidinstrument für chirurgische Operationen bestehend aus einem langem Körper (1) mit einem Griffteil (2) und einem vorderen Hakenteil (3) mit Widerlager (4), sowie einem Führungsrungsrohr (5), welches in seinem Inneren ein Rohrstück (6) mit eine Schneidkrone (7) besitzt und das andere Griffteil (8) mit dem gabelförmigen Scharnierkopf (9) ist durch ein Scharnier (10) an den Körper (1) angelenkt, und durch eine Blattfeder (11) mit dem Griffteil (2) verbunden. Der gabelförmigen Scharnierkopf (9) greift zwischen die Abstandstücke (12) und (13) wobei das Abstandsstück (13) ein sch rag verzahntes Zahnrad darstellt, welches in eine Zahnsange (14) so eingreift, daß das Rohrstück (6) beim vorwärts- und rückwärtsbewegen eine Drehung ausführt.The construction is shown in Fig. 1. Cutting instrument for surgical operations consisting of a long body (1) with a handle part (2) and a front hook part (3) with abutment (4), as well as a guide tube (5) which has a tube section (6) with a cutting crown (7) inside it and the other handle part (8) with the fork-shaped hinge head (9) is hinged to the body (1) by a hinge (10) and connected to the handle part (2) by a leaf spring (11). The fork-shaped hinge head (9) engages between the spacers (12) and (13), whereby the spacer (13) represents a helically toothed gear which engages in a toothed gear (14) in such a way that the tube section (6) rotates when moving forwards and backwards.

Das Schneidwerkzeug wird durch die Hand des Chirurgen an das Operationsfeld angesetzt und durch Druckbewegungen bewirkt die Schneidkrone ein Entfernen des Gewebeteiles. Die Rückbewegung wird durch die Blattfeder bewirkt. Die Schneidtreste der Operationswunde verbleiben im Rohrstück wobei die Konstruktion der Schneidkrone ein herausfallen verhinderd. Dadurch wird der Chirurg von dem eigentlichen Operationsprozess nicht abgelenkt.The cutting tool is placed on the surgical field by the surgeon's hand and the cutting crown removes the tissue by applying pressure. The return movement is caused by the leaf spring. The cutting residues from the surgical wound remain in the tube piece and the design of the cutting crown prevents them from falling out. This means that the surgeon is not distracted from the actual surgical process.
