Abstract

The film roll hinge joint principle described in the patent claims can be used to replace all hinge-like joints of the human body without any loss of function. The largely unresolved problems of prostheses implanted at present, such as abrasion, foreign-body reactions and insufficient load-bearing capacity, are avoided by the film roll hinge joint principle. On the one hand it is possible to transmit the physiological loads without any problems even in the presence of unfavourable load conditions, and on the other hand foreign-body reactions caused by abrasion in the joint region are ruled out. The joint is constructed such that the hinge bands extending crosswise are under a tensile load while all other joint components are under a compressive load. The joint partners connected to each other by film hinges roll on each other on movement, so that there can be no relative movement whatsoever between the joint surfaces and thus no abrasion. As a result of suitable positioning of the hinge bands these are loaded mechanically to only a small extent.

Description

Bezeichnung: Film-Roll-Scharniergelenk als Endo-Designation: Film-roll hinge joint as an endo-

prothese für scharnierähnliche Gelenke des menschlichen Körpers Stand der Technik Endoprothesen für Ellenbogengelenke aus Metall-Polyäthylen-Paarungen, Silikonkautschuk oder isoelastischem Kunststoffmaterial sind noch nicht endgültig ausgereift. Die Fixation i Knochen, die Langzeitstabilität im Körpermilieu und der Abrieb der Werkstoffe führt in vielen Fällen zu komplikationen. prosthesis for hinge-like joints in the human body was standing technology endoprostheses for elbow joints made of metal-polyethylene pairings, Silicone rubber or isoelastic plastic material are not final yet mature. The fixation in the bones, the long-term stability in the body environment and the Abrasion of the materials leads to complications in many cases.

Im Augenblick stehen für den totalen Ellenbogengelenkersatz Dl gende Prothesentypen zur Verfügung: a) Systeme zum Gelenkteilersatz aus Silikonkautschuk oder isoelastischem Material, b) Silastic-Prothesen aus Silikonkautschuk, die gewöhnlich aus einem Stück bestehen, c) reine Scharnierprothesen aus Metall-Metall- oder Metall-Polyäthylen-Paarungen, d) isoelastische Prothesen aus Kunststoff, in der gei Scharnierprothesen, e) Endoprothesen aus Metall-Polyäthylen-Paarungen, nie weitgehend die natürlichen Verhältnisse am Ellenbogengelenk nachahmen.At the moment there are some things that stand for total elbow joint replacement Types of prostheses available: a) Systems for replacing joint parts made of silicone rubber or isoelastic material, b) Silastic prostheses made of silicone rubber, usually consist of one piece, c) pure hinge prostheses made of metal-metal or metal-polyethylene pairings, d) isoelastic prostheses made of plastic, in the gei hinge prostheses, e) endoprostheses made of metal-polyethylene pairings, never largely the natural conditions Mimic the elbow joint.

In Tabelle 1 sind die zur Zeit üblichen Prothesentypen sowie die für diese Prothese angemeldeten Patente aufgelistet.Table 1 shows the currently common types of prostheses and those for this prosthesis listed patents pending.

Sllt dem durch di. Patentansprüche beschriebenen Film-Roll-Scharniergelenkprinzip können alle scharnierähnliche Gelenke des menschlichen Körpers ohne Funktionsverlust ersetzt werden.Sllt through di. Film-roll hinge-joint principle described in the patent claims can use all hinge-like joints in the human body without any loss of function be replaced.

Bild i zeigt die prinzipielle Arbeitsweise des Gelenkes. Die durch Filmscharniere verbundenen Gelenkpartner rollen bei der Bewegung aufeinander ab, so daß zwischen den Gelenkflächen keinerlei Relativbewegung und damit kein Abrieb entstehen kann.Figure i shows the principle of operation of the joint. By Joint partners connected to the film hinge roll off each other when moving, so that no relative movement whatsoever between the joint surfaces and therefore no abrasion can arise.

Durch eine geeignete Lage der Scharnierbänder werden diese nur in geringem Maße mechanisch belastet, so daß sehr hohe Lebensdauern sowie hohe Sicherheiten gegen überlast möglich sind.With a suitable position of the hinge straps, these are only available in mechanically stressed to a small extent, so that very long lifetimes and high levels of security against overload are possible.

Je nach Belastung des Gelenkes und abhängig von dem nach der Operation verbleibendem natürlichen Bandapparat des Gelenkes kann das Scharnierband einteilig (Bild 1 a) oder gekreuzt (Bild 1 b) ausgeführt werden.Depending on the load on the joint and depending on what happened after the operation The hinge can be made in one piece with the remaining natural ligaments of the joint (Picture 1 a) or crossed (picture 1 b).

Das Gelenk ist so konstruiert, daß die über Kreuz verlaufenden Scharnierbänder -lur Zug, alle anderen Gelenkbestandteile auf Druck belastet sind. Die auf das Gelenk von außen wirkenden resultierenuen Kräfte (Bild 2) sind in Bild 3 für mehrere Armstellungen und Belastungen dargestellt.The joint is constructed in such a way that the hinge straps cross -Lur train, all other joint components are under pressure. The one on the joint The resulting external forces (Fig. 2) are shown in Fig. 3 for several arm positions and loads shown.

Die weitgehend ungelösten Probleme der zur Zeit implantierten Prothesen wie Abrieb, Fremdkörperreaktionen und unzureichende Lastaufnahme werden durch das Film-Roil-Scharnierprinzip ver-; den.The largely unsolved problems of currently implanted prostheses such as abrasion, foreign body reactions and insufficient load absorption are affected by the Film-roil hinge principle; the.

Einerseits kannen die physiologischen Belastungen, auch bei unqünstigen Belastungsverhältnissen, problemlos übertragen werden, andererseits sind Fremdkörperreaktionen, die durch Abrieb im Gelenkbereich verursacht werden, ausgeschlossen.On the one hand, the physiological stress, even if it is unfavorable Load conditions, can be transferred without any problems, on the other hand foreign body reactions are caused by abrasion in the joint area are excluded.
