Die Erfindung bezieht sich auf eine Fingergelenk-Endoprothese als weitere Ausbildung des Hauptpatentes...Az.: P 25 49 819.5-35.The invention relates to a finger joint endoprosthesis as further training of the main patent ... Ref .: P 25 49 819.5-35.
Bei bekannten Fingergelenk-Endoprothesen (US-PS 3 991 425) greifen zwei überbrückte,mit einem Stiel im Fingerknochen zu verankernde, parallele, kreisförmige Kufen beidseitig eines Steges des anderen, ebenfalls mit einem Stiel zu verankernden Gelenkteiles in kreisförmige Gleitflächen ein, wobei der Steg die Kufen innenseitig führt. Dadurch können die Fingerteile eine Beugebewegung in nur einer, praktisch senkrecht zur Handfläche liegenden Ebene und ggf.Use known finger joint endoprostheses (US Pat. No. 3,991,425) two bridged, parallel, circular ones to be anchored with a stalk in the finger bone Runners on both sides of a web of the other, also to be anchored with a handle Joint part in circular sliding surfaces, the web of the runners on the inside leads. This allows the finger parts to flexure in just one, convenient plane perpendicular to the palm and, if necessary,
auch eine kleine Bewegung in Fingerlängsrichtung ausführen.also make a small movement in the longitudinal direction of the finger.
Die Aufgabe der Erfindung besteht darin, eine Fingergelenk-Endopr these so auszubilden, daß der Kufengelenkteil in Beugestellungen trotz einer Verbindung der beiden Gelenkteile eine sich automatisch anpassende begrenzte Abroll- und Gleitbewegung in Anpassung an unterschiedliche Hände zur Handinnenseite ausführen kann und eine begrenzte Bewegung in Fingerlängsrichtung zuläßt und daß die beiden Gelenkteile auch eine begrenzte Drehbewegung des einen zum anderen Fingerteil zulassen, ohne daß eine Schraubmontage beim Einbau der Prothese erforderlich ist.The object of the invention is to provide a finger joint Endopr to train these so that the skid joint part in flexed positions despite a connection of the two joint parts an automatically adapting limited rolling and sliding movement in adaptation to different hands on the inside of the hand and a allows limited movement in the longitudinal direction of the fingers and that the two joint parts also allow a limited rotational movement of one part of the finger to the other without that a screw assembly at Installation of the prosthesis is required.
Diese Aufgabe wird durch das Kennzeichen des Anspruchs 1 gelöst, dessen Merkmale zwar bei Kniegelenk-Endoprothesen im wesentlichen bekannt sind, zur bei Anwendung auf Finyergelenk-Endoprothesen zu neuen und überraschenden Fsgebnissen führen.This object is achieved by the characterizing part of claim 1, of which Characteristics of knee joint endoprostheses are essentially known for Application to Finyer joint endoprostheses to new and surprising results to lead.
Durch die Lösung nach der Erfindung-~kann der Kufenteil der Prothese bei Beugebewegungen der Fingerglieder eine individuelle Bewegung zur Handinnenseite ausführen und dabei frei abrollend auf den Gleitflächen des anderen Gelenkteiles gleiten. Während der Beugebewegung ist durch die Ausbildung des Steges und des Abstandes der Kufen auch eine begrenzte Drehbewegung des Gleitflächen-Gelenkteiles gegenüber dem Kufen-Gelenkteil ermöglicht.The solution according to the invention- ~ the runner part of the prosthesis with flexing movements of the phalanges an individual movement to the inside of the hand run and roll freely on the sliding surfaces of the other joint part slide. During the flexion movement is due to the formation of the bar and the distance the runners also have a limited rotational movement of the sliding surface joint part opposite the skid joint part allows.
Durch die Lösung nach der Erfindung ist das Gelenk als Einheit dadurch herzustellen, daß der Stufenteil mit den offenen Nutenenden über die Zapfenenden des Gleitflächenteiles gehakt wird. Bei allen Bewegungen ist der im Steg Le.cg-erte Zapfen nicht belastet und hat nur Führungsaufgaben.By the solution according to the invention, the joint is thereby as a unit produce that the step part with the open groove ends over the pin ends of the sliding surface part is hooked. In all movements, the one in the bridge is Le.cg-erte Zapfen not burdened and only has management tasks.
Die Erfindung wird nachstehend arffiand der Zeichnung erläutert. Es zeigen: Fig. 1 die Seitenansicht eines Fingers mit schematischen teilweisem Längsschnitt durch eine Fingergelenk-Endoprothese, Fig. 2 eine vergrößerte Seitenansicht der Prothese nach Fig. 1 Fig. 3 eine Ansicht zu Fig. 2 in Richtung des Pfeiles III der Fig. 2 Fig. 4 eine Ansicht des Gelenkes von der Handinnenseite aus gesehen, Fig. 5 einen Schnitt nach Linie V-V der Fig. 2, Fig. 6 einen Schnitt nach Linie VI-VI der Fig. 5, Fig. 7 eine Seitenansicht des Steggelenkteiles, Fig. 8 eine Aufsicht auf den Gelenkteil nach Fig. 7.The invention is explained below arffiand the drawing. It 1 shows the side view of a finger with a schematic partial longitudinal section through a finger joint endoprosthesis, Fig. 2 is an enlarged side view the prosthesis according to FIG. 1, FIG. 3 is a view of FIG. 2 in the direction of arrow III Fig. 2 Fig. 4 is a view of the joint seen from the inside of the hand, 5 shows a section along line V-V of FIG. 2, FIG. 6 shows a section along the line VI-VI of FIG. 5, FIG. 7 shows a side view of the bar joint part, FIG. 8 shows a plan view on the joint part according to FIG. 7.
Die Fingergelenk-Endoprothese besteht aus einem ersten Gelenkteil 1 und einem zweiten Gelenkteil 2, die durch Stiele 3 und 4 in den Finger- oder Mittelhandknochen verankert werden. Der Gelenkteil 1 ist mit einem mittigen zur Mittelhand gerichteten, sich von oben zur Innenseite des Fingers verbreiternden Sattel steg 5 versehen, der vorn oben eine Anschlagnase 6 und auf der ins Handinnere gerichteten Hälfte eine größere Höhe besitzt. Im Bereich dieser Steghälfte ist ein Querzapfen 7 exzentrisch gegen die Wölbung der bogenförmigen beidseitigen Gleitflächen 8 des Teiles 1 nach innen verlagert befestigt, dessen Enden vorteilhaft konisch auslaufen.The finger joint endoprosthesis consists of a first joint part 1 and a second joint part 2 passing through stalks 3 and 4 in the finger or metacarpal bones be anchored. The joint part 1 is with a central to the metacarpal, from above to the inside of the finger widening saddle web 5 provided, the one at the front above a stop lug 6 and on the half facing into the inside of the hand has a greater height. A transverse pin 7 is eccentric in the area of this web half against the curvature of the arcuate sliding surfaces 8 of the part 1 on both sides fixed internally shifted, the ends of which taper advantageously conically.
Beidseitig des Sattelsteges 5 sind die Gleitflächen 8 im Querschnitt ausgekehlt und von innen zur Fingeroberseite ebenso wie der Steg 5 verjüngt.On both sides of the saddle bridge 5, the sliding surfaces 8 are in cross section grooved and tapered from the inside to the top of the finger just like the web 5.
Der zur Mittelhand liegende Prothesenteil 2 ist mit Kufen 9 versehen, deren Gleitflächen bzw. Abrollflächen den Gleitflächen 8 des anderen Gelenkteiles 1 angepaßt sind. Die Kufen 9 sind bei 10 überbrückt, und diese Überbrückung 10 legt sich in der Strecklage der Fingerglieder gegen die vordere Nase 6 des Sattelsteges 5.The prosthesis part 2 lying on the metacarpal is provided with runners 9, their sliding surfaces or rolling surfaces the sliding surfaces 8 of the other joint part 1 are adapted. The runners 9 are bridged at 10, and this bridging 10 sets in the extended position of the phalanges against the front nose 6 of the saddle bridge 5.
Das innenseitige Ende der Kufen 9 ist bei 9 a über die Fläche der Überbrückung 10 hinaus verlängert.The inside end of the runners 9 is at 9 a over the surface of the Bridging 10 extended beyond.
Die Kufen 10 sind auf den einander zugekehrten Flächen je mit einer zur Kufengleitfläche etwa parallelen Führungsnut 11 versehen, deren Weite größer ist als der Durchmesser der Enden des Querzapfens 7 und die sich im Querschnitt zum Nutenboden vorteilhaft ebenfalls verjüngen.The runners 10 are each with one on the facing surfaces to the runner sliding surface approximately parallel guide groove 11 is provided, the width of which is greater is than the diameter of the ends of the transverse pin 7 and which is in cross section It is also advantageous to taper towards the bottom of the groove.
Die Führungsnuten 11 sind im Bereich der Kufenverlängerungen 9 a offen, so daß der Gelenkteil 1 mit den offenen Nutenenden in einer größeren Beugelage über den Zapfen 7 gehakt und dann in die Strecklage gebracht werden kann, wobei die Zapfen 7 in den Nuten 11 frei gleiten können.The guide grooves 11 are open in the area of the runner extensions 9 a, so that the joint part 1 with the open groove ends in a larger bent position the pin 7 can be hooked and then brought into the extended position, with the pin 7 can slide freely in the grooves 11.
Durch den sich von oben nach innen verbreiternden Sattelsteg 9 und die sich umgekehrt in der Breite verjüngenden Gleitflächen 8 des Gelenkteiles 1 und der Kufen 9 ist eine feste Lage der Gelenkteile 1 und 2 zueinander nur in der Strecklage des Gelenkes gewährleistet, während bei einleitender Beugebewegung sich der Gelenkteil 2 zunächst mit dem oberen Teil gegenüber dem Gelenkteil 1 etwas nach oben-bewegt, wie es bei einem gesunden Fingergelenk der Fall ist, und dabei besitzt der Teil 2 durch das Spiel zwischen dem Führungszapfen 7 und den Nuten 11 eine freie Bewegungsmöglichkeit, durch die sich der Teil 2 je nach Ansatz der durch die obere Auskehlung der Überbrückung 10 verlaufenden Strecksehne in seiner Bewegung nach oben anpaßt und dadurch Überdehnungen der Strecksehne ausschaltet. Durch das vorerwähnte Spiel und den sich nach innen verjüngenden Verlauf der Gleitflächen und Kufen ist auch in allen Beugelagen eine begrenzte Drehbewegung der Fingerglieder zueinander möglich.By widening from the top inward saddle bridge 9 and the reverse sliding surfaces 8 of the joint part 1, which taper in width and the runners 9 is a fixed position of the joint parts 1 and 2 to each other only in the Extended position of the joint guaranteed, while the initial flexion movement the joint part 2 initially with the upper part opposite the joint part 1 some moved upwards, as is the case with a healthy finger joint, and doing so the part 2 possesses due to the play between the guide pin 7 and the grooves 11 a free movement, through which part 2, depending on the approach of the the upper groove of the bridging 10 extending extensor tendon in its movement adapts upwards and thereby eliminates overstretching of the extensor tendon. By the the aforementioned game and the inwardly tapering course of the sliding surfaces and runners, there is a limited rotational movement of the phalanx even in all joints possible to each other.
Um den Abrieb der Fingergelenk-Endoprothese so gering wie möglich zu halten, werden die Gelenkteile 1 und 2 vorteilhaft aus einem Aluminiumoxyd (Sintererde) hergestellt.To keep the abrasion of the finger joint endoprosthesis as low as possible to keep, the joint parts 1 and 2 are advantageously made of an aluminum oxide (sintered earth) manufactured.
