Description
Die Erfindung betrifft ein Inlay-Entfernungsinstrumentarium für eine Totalendoprothese mit einer inlaytragenden Außenpfanne.The invention relates to an inlay removal instrument for Total endoprosthesis with an inlay-bearing outer cup.
Sie betrifft ein Operationsinstrument zum Entfernen von Inlays, die insbesondere als Hüftgelenk-Endoprothesen-Innenpfannen aus hochwertigen Kunststoffen ausgebildet sind und in Knochen befe stigten Außenpfannen verankert sind.It relates to a surgical instrument for removing Inlays, in particular as hip joint endoprosthesis inner pans are made of high quality plastics and befe in bone external pans are anchored.
Bei Verschleiß insbesondere der Hüftgelenk-Teil- oder Totalendopro these oder Entzündungen an der inlaytragenden Außenpfanne sind die Inlays zu entfernen.If there is wear, especially the hip joint or total endopro These or inflammations on the inlay-bearing outer pan are the Remove inlays.
In der Operationspraxis erfolgt das derzeitig manuell nicht nur sehr zeitaufwendig, sondern mit viel Geschick und Kraftaufwand durch den Spezialisten.In surgical practice, this is currently not only done manually very time consuming, but with a lot of skill and effort the specialists.
Es ist Ziel der Erfindung, Inlays einfach, zeit- und kraftsparend und ohne Zerstörung der inlaytragenden Außenpfanne und ohne Gewe beverletzungen zu entfernen.The aim of the invention is to make inlays simple, time-saving and energy-saving and without destroying the inlay-bearing outer pan and without tissue remove injuries.
Erfindungsgemäß wird das dadurch erreicht, daß mindestens eine nicht endlose Schneide oder mindestens zwei Spit zen, die an mindestens einem konzentrisch beweglichen Trägerteil angeordnet sind und dessen konzentrische Bewegung über eine konisch geformte Treibspindel oder über Keil elemente erfolgt und somit einen Form- und/oder Kraftschluß mit dem Inlay ermöglicht, und daß das Inlay entweder über eine an sich bekannte gewin dewirksame und mit dem Trägerteil verbundene, sich auf der inlaytragenden Außenpfanne abstützende und eine Kraft in Ausheberichtung erzeugende Aus hebevorrichtung oder über ein mit dem Trägerteil verbundenes bereits bekanntes Ham merteil durch Schlagwirkung aus der Außenpfanne entfernbar ist.According to the invention this is achieved in that at least one not endless cutting edge or at least two spits zen on at least one concentrically movable support part are arranged and its concentric movement over a conical drive spindle or over wedge elements takes place and thus a positive and / or frictional connection with the Inlay allows, and that the inlay either over a known per se effective and connected to the carrier part, on the supporting inlay-bearing outer pan and generating a force in the lifting direction lifting device or via an already known ham connected to the carrier part Part of it can be removed from the outer pan by impact is.
Im Ausführungsbeispiel nach Fig. 1 und 2 sind 3 Schneiden (3) an jeweils einem zugehörenden Trägerteil (2) angebracht, die durch eine konisch geformte und F₁-krafteinleitende Treibspin del (5) konzentrisch nach außen und so mit dem halbkugelförmigen Inlay (1) Form- und oder Kraftschluß erwirken. An den Trägertei len (2) ist ein bekanntes aber nicht dargestelltes Hammerteil ange bracht, womit die Schlagwirkung F₂ erzeugt und somit das Inlay (1) aus der Außenpfanne (4) entfernt werden kann.In the embodiment according to FIGS. 1 and 2, 3 cutting edges ( 3 ) are each attached to an associated carrier part ( 2 ), which is concentrically directed outwards by a conically shaped and F₁-force-introducing driving spindle ( 5 ) and thus with the hemispherical inlay ( 1 ) Get positive and or non-positive. On the Trägertei len ( 2 ) is a known but not shown hammer part is introduced, which creates the impact F₂ and thus the inlay ( 1 ) can be removed from the outer pan ( 4 ).
