Abstract
Die Erfindung betrifft ein chirurgisches Implantat, wobei mindestens ein Element des chirurgischen Implantats zur Aufnahme von Kräften und/oder zur Ermöglichung einer Längenänderung mindestens eine Evolutfeder umfasst.The invention relates to a surgical implant, wherein at least one element of the surgical implant for receiving forces and / or for facilitating a change in length comprises at least one evolute spring.
Description
Die Erfindung betrifft ein chirurgisches Implantat, wobei mindestens ein Element des chirurgischen Implantats zur Aufnahme von Kräften und/oder zur Ermöglichung einer Längenänderung mindestens eine Evolutfeder umfasst, gemäß Patentanspruch 1.The invention relates to a surgical implant, wherein at least one element of the surgical implant for receiving forces and / or for facilitating a change in length comprises at least one evolute spring according to claim 1.
Des Weiteren betrifft die Erfindung ein chirurgisches Implantat, welches zur Aufnahme von Kräften und/oder zur Ermöglichung einer Längenänderung mindestens eine Evolutfeder umfasst, gemäß Patentanspruch 2.Furthermore, the invention relates to a surgical implant, which comprises at least one evolute spring for receiving forces and / or for enabling a change in length, according to claim 2.
Der Nachteil hinsichtlich bislang bekannter chirurgischer Implantate ist darin zu sehen, dass diese Implanate keine großen Längenänderung hinsichtlich des Implantates selber ermöglichen. Des Weiteren können die chirurgischen Implantate oftmals nicht gleichzeitig Druck-, Zug-, Biege-, Scher- und Torisionskräfte aufnehmen und zusätzlich eine Längenänderung ermöglichen.The disadvantage with regard to hitherto known surgical implants is the fact that these implants do not allow a great length change with regard to the implant itself. Furthermore, the surgical implants often can not simultaneously absorb compressive, tensile, bending, shear and Torictionskräfte and also allow a change in length.
Aus dem Vorgenannten ist es daher Aufgabe der vorliegenden Erfindung ein chirurgisches Implantat anzugeben, welches sowohl die Aufnahme von Kräften als auch eine Längenänderung ermöglicht.From the foregoing, it is therefore an object of the present invention to provide a surgical implant, which allows both the absorption of forces and a change in length.
Die Lösung der Aufgabe erfolgt durch ein chirurgisches Implantat gemäß Patentanspruch 1. Des Weiteren erfolgt die Lösung der Aufgabe durch ein chirurgisches Implantat nach Patentanspruch 2. Die jeweiligen Unteransprüche stellen mindestens zweckmäßige Ausgestaltungen und Weiterbildungen dar.The object is achieved by a surgical implant according to claim 1. Furthermore, the object is achieved by a surgical implant according to claim 2. The respective subclaims represent at least expedient refinements and developments.
Erfindungsgemäß umfasst mindestens ein Element des chirurgischen Implantats zur Aufnahme von Kräften und/oder zur Ermöglichung einer Längenänderung eine Evolutfeder.According to the invention, at least one element of the surgical implant for receiving forces and / or for enabling a change in length comprises an evolute spring.
In anderen Worten weist ein chirurgischen Implantat, sofern dieses mehrere Elemente umfasst, mindestens eine Evolutfeder auf, wobei diese Evolutfeder mindestens einem Element bzw. einem Teilelement des chirurgischen Implantats zuzuordnen ist. Demnach ist es auch möglich, dass mindestens ein Element des chirurgischen Implantats als Evolutfeder ausgebildet ist oder mindestens ein Element des chirurgischen Implantats eine Evolutfeder aufweist.In other words, a surgical implant, if it comprises a plurality of elements, at least one Evolutfeder, said Evolutfeder is assigned to at least one element or a sub-element of the surgical implant. Accordingly, it is also possible that at least one element of the surgical implant is designed as an evolute spring or at least one element of the surgical implant has an evolute spring.
Gemäß einem nebengeordnetem Aspekt der Erfindung kann ein chirurgisches Implantat zur Aufnahme von Kräften und/oder zur Ermöglichung einer Längenänderung mindestens eine Evolutfeder umfassen. Dies ist beispielsweise dann der Fall, wenn ein chirurgisches Implantat lediglich ein Element umfasst, bzw. lediglich aus einem Element besteht.According to a subsidiary aspect of the invention, a surgical implant for receiving forces and / or for enabling a change in length may comprise at least one evolutive spring. This is the case, for example, when a surgical implant comprises only one element or only consists of one element.
In anderen Worten kann ein chirurgisches Implantat zur Aufnahme von Kräften und/oder zur Ermöglichung einer Längenänderung mindestens eine Evolutfeder aufweisen.In other words, a surgical implant for receiving forces and / or for facilitating a change in length may comprise at least one evolutive spring.
Bei den aufgenommen Kräften handelt es sich um Zugkräfte und/oder Druckkräfte und/oder Torsionskräfte und/oder Scherkräfte und/oder Biegekräfte. Die genannten Kräfte können einzeln oder in beliebiger Kombination von der Evolutfeder aufgenommen werden.The absorbed forces are tensile forces and / or pressure forces and / or torsional forces and / or shear forces and / or bending forces. The forces mentioned can be absorbed individually or in any combination of the Evolutfeder.
Bei der zu ermöglichenden Längenänderung handelt es sich um Längenänderungen hinsichtlich des chirurgischen Implantates selbst. Demnach soll es ermöglicht werden, dass das chirurgische Implantat von einem Ausgangszustand bzw. einer Ausgangsposition im implantierten Zustand aufgrund der damit verbundenen Zug-, Druck-, Biege-, Scher-, bzw. Torsionskräften in eine notwendige Position mit Längenänderung überführt werden kann.The length change that is to be made possible are changes in length with regard to the surgical implant itself. Accordingly, the surgical implant is to be allowed to move from an initial state or an initial position in the implanted state due to the associated tensile, compressive, bending, shear -, or torsional forces can be converted into a necessary position with length change.
Als Evolutfeder werden derartige Federn bezeichnet, welche aus einem hochkant stehenden Flachmaterial gewickelt sind. Derartige Evolutfedern werden auch als Wickelfedern bzw. Topffedern bezeichnet. Auch der Begriff bailliesche Schneckenfeder ist bekannt. Häufigste Anwendung sogenannter Evolutfedern erfolgt in Gartenscheren.As Evolutfeder such springs are referred to, which are wound from an upright standing flat material. Such Evolutfedern are also referred to as coil springs or pot feathers. Also the term bailliesche worm spring is known. The most common application of so-called evolute springs is in secateurs.
In einer Ausführungsform der Erfindung ist die mindestens eine Evolutfeder mehrgängig, insbesondere mindestens 2-gängig, ausgebildet. Auch die Verwendung bzw. Ausbildung von 3-gängigen, 4-gängigen, 5-gängigen Evolutfedern usw. ist denkbar.In one embodiment of the invention, the at least one Evolutfeder more frequent, in particular at least 2-way formed. The use or training of 3-speed, 4-speed, 5-speed Evolutfedern etc. is conceivable.
Die mindestens eine Evolutfeder ist vorzugsweise aus Metall, insbesondere aus Titan, gefertigt. Prinzipiell kann die Evolutfeder aus allen derartigen Materialien gefertigt sein, welche sowohl die Aufnahme von Zug-, Druck-, Biege-, Scher-, und Torsionskräften ermöglicht und des Weiteren eine Längenänderung hinsichtlich des chirurgischen Implantates ermöglicht.The at least one Evolutfeder is preferably made of metal, in particular of titanium. In principle, the Evolutfeder can be made of all such materials, which allows both the recording of tensile, compressive, bending, shear, and torsional forces and further allows a change in length with respect to the surgical implant.
Die mindestens eine Evolutfeder kann beispielsweise in ein schalenförmiges Element des chirurgischen Implantats eingearbeitet sein. In anderen Worten umfasst ein schalenförmiges Element eines chirurgischen Implantats mindestens eine Evolutfeder bzw. weist mindestens eine Evolutfeder auf.The at least one Evolutfeder can be incorporated for example in a cup-shaped element of the surgical implant. In other words, a cup-shaped element of a surgical implant comprises at least one Evolutfeder or has at least one Evolutfeder.
Des Weiteren ist es möglich, dass die mindestens eine Evolutfeder in ein stabförmiges Element des chirurgischen Implantats eingearbeitet ist. In anderen Worten umfasst ein stabförmiges Element eines chirurgischen Implantats mindestens eine Evolutfeder bzw. weist mindestens eine Evolutfeder auf.Furthermore, it is possible that the at least one evolute spring is incorporated in a rod-shaped element of the surgical implant. In other words, a rod-shaped element of a surgical implant comprises at least one Evolutfeder or has at least one Evolutfeder.
In einer weiteren Ausführungsform der Erfindung ist es möglich, dass mindestens eine Evolutfeder, vorzugsweise mehrere Evolutfedern, zwischen zwei plattenartigen Elementen des chirurgischen Implantats angeordnet ist bzw. sind. Die plattenartigen Elemente können konvex und/oder konkav gekrümmte Abschnitte aufweisen.In a further embodiment of the invention, it is possible that at least one Evolutfeder, preferably a plurality of Evolutfedern is disposed between two plate-like elements of the surgical implant or are. The plate-like elements may have convex and / or concave curved portions.
Ebenfalls ist es möglich, dass die mindestens eine Evolutfeder in einem rohrförmigen Element angeordnet ist. In anderen Worten umfasst ein rohrförmiges Element eines chirurgischen Implantats mindestens eine Evolutfeder bzw. weist mindestens eine Evolutfeder auf.It is also possible that the at least one Evolutfeder is arranged in a tubular element. In other words, a tubular element of a surgical implant comprises at least one Evolutfeder or has at least one Evolutfeder.
Bei dem chirurgischen Implantat kann es sich beispielsweise um einen Gelenkersatz oder eine Knochenschraube oder einen Verbindungsstab oder einen Knochenersatz oder um ein Implantat zur Implantierung im Bereich der Wirbelsäule oder eine Bandscheibenprothese handeln.The surgical implant can be, for example, a joint replacement or a bone screw or a connecting rod or a bone substitute or an implant for implantation in the area of the spinal column or an intervertebral disc prosthesis.
Bei Gelenkersatz-Implantaten und/oder Prothesen und/oder Teilprothesen kann mindestens eine Evolutfeder beispielsweise bei Knieprothesen oder Knieendoprothesen oder bei Hüftgelenkprothesen oder bei Schultergelenkprothesen oder bei Fingergelenkprothesen vorgesehen sein.In joint replacement implants and / or prostheses and / or partial dentures, at least one evolutic spring may be provided, for example, in the case of knee prostheses or knee endoprostheses or in hip joint prostheses or in shoulder joint prostheses or in finger joint prostheses.
Die Evolutfeder kann in diesen Fällen beispielsweise in ein schalenförmiges Gelenkelement und/oder in ein Kernelement eines Gelenkersatz-Implantates eingearbeitet sein. In anderen Worten umfasst ein schalenförmiges Gelenkelement und/oder ein Kernelement der Gelenkersatz-Implantate und/oder der Prothese und/oder der Teilprothese mindestens eine Evolutfeder.The Evolutfeder can be incorporated in these cases, for example, in a cup-shaped joint element and / or in a core element of a joint replacement implant. In other words, a cup-shaped joint element and / or a core element of the joint replacement implants and / or the prosthesis and / or the partial denture comprises at least one evolutive spring.
Bei einer Knochenschraube kann es sich beispielsweise um eine Pedikelschraube oder eine Fixierungsschraube handeln. Mindestens eine Evolutfeder kann beispielsweise in einen Schraubenschaft und/oder in ein Kopfelement und/oder in ein Element, welches sich im Inneren des Kopfelements befindet, eingearbeitet sein. In anderen Worten umfasst ein Schraubenschaft und/oder ein Kopfelement und/oder ein Element, welches sich im Inneren des Kopfelements befindet, mindestens eine Evolutfeder.For example, a bone screw may be a pedicle screw or a fixation screw. At least one Evolutfeder can be incorporated, for example, in a screw shaft and / or in a head element and / or in an element which is located in the interior of the head member. In other words, a screw shaft and / or a head element and / or an element, which is located in the interior of the head element, comprises at least one evolutive spring.
Die mindestens eine Evolutfeder kann auch in Implantate, welche im Bereich der Wirbelsäule implantiert werden, eingearbeitet und/oder angeordnet sein. Bei derartigen Implantaten kann es sich um Bandscheibenprothesen oder Bandscheibenendoprothesen oder um Pedikelschrauben oder um Wirbelkörperersatzimplantate handeln. In anderen Worten umfasst beispielsweise eine Bandscheibenprothese oder eine Bandscheibenendoprothese oder eine Pedikelschraube oder ein Wirbelkörperersatzimplantat mindestens eine Evolutfeder bzw. weist mindestens eine Evolutfeder auf.The at least one evolute spring can also be incorporated and / or arranged in implants which are implanted in the area of the spinal column.
