Abstract

It is the object of the invention to remove inlays in simple, time-saving and force-saving manner as compared with the current manual operation practice and without destruction of the external cups carrying the inlays and without any injury to the tissues. Solution of the problem Positive and/or non-positive connection to the inlay takes place via at least one, preferably non-endless, blade (3) or at least two tips located on at least one concentrically moveable carrier member (2), and via conventional force-introducing devices, and the inlay can be removed with conventional lifting devices. Field of application The invention is particularly suitable in orthopaedics for removal of inlays in total endoprostheses. <IMAGE>

Description

Die Erfindung betrifft ein Operationsinstrument zum Entfernen von Inlays, die insbesondere als Hüftgelenk-Endoprothesen-Innenpfannen aus hochwertigen Kunststoffen ausgebildet sind und in Knochen befe­ stigte Außenpfannen verankert sind.The invention 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 vorzugsweise nicht endlose Schneide (3) oder mindestens zwei Spit­ zen, die an mindestens einem konzentrisch beweglichen Trägerteil (2) angeordnet sind und dessen konzentrische Bewegung über an sich bekannte konisch geformte Treibspindel (5) oder über bekanntes Keil­ element erfolgt und somit Form- und oder Kraftschluß (F₁) mit dem Inlay (1) ermöglichen und dieses entweder über eine bekannte gewin­ dewirksame und mit dem Trägerteil (2) verbundene und sich auf der inlaytragenden Außenpfanne (4) abstützende und F₂ erzeugende Aus­ hebevorrichtung oder über ein mit dem Trägerteil (2) verbundenes bereits bekanntes Ham­ merteil durch Schlagwirkung F₂ aus der Außenpfanne (4) entfernt wird. According to the invention this is achieved in that at least one preferably non-endless cutting edge ( 3 ) or at least two points, which are arranged on at least one concentrically movable carrier part ( 2 ) and whose concentric movement via known conical drive spindle ( 5 ) or over Known wedge element takes place and thus positive and / or frictional connection (F₁) with the inlay ( 1 ) and this either via a known thread-effective and with the support part ( 2 ) connected and on the inlay-bearing outer pan ( 4 ) supporting and F₂ generating From lifting device or via an already known Ham merteil connected to the carrier part ( 2 ) is removed by impact F₂ from the outer pan ( 4 ).

AusführungsbeispielEmbodiment

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 ) Obtain 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 ).
