Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Ausfräsen einer Ausnehmung zur Halterung eines Objektes, die einen Fräskopf, einen Rotationsantrieb für den Fräskopf sowie eine Positioniereinrichtung für den Fräskopf aufweist.The The invention relates to a device for milling a recess for mounting an object that has a milling head, a rotary drive for the milling head and has a positioning device for the milling head.
Derartige Fräseinrichtungen sind in vielfältigen Ausführungsformen bekannt und werden in diversen technischen Bereichen eingesetzt. Insbesondere ist es auch bereits bekannt, Fräseinrichtungen im Bereich der Hüftchirurgie zu verwenden, um im Knochenbereich Kavitäten zur Aufnahme einer Hüftgelenkprothese zu erzeugen. Gemäß dem Stand der Technik werden die erforderlichen Kavitäten unter Verwendung eines Formfräsers erzeugt, der beispielsweise eine kalottenförmige Kavität erzeugt.such Milling devices are in diverse embodiments known and used in various technical fields. In particular, it is also already known milling devices in the field of Hip surgery to use in the bone area cavities for receiving a hip joint prosthesis to create. According to the state The technique requires the required cavities using a form cutter generated, for example, generates a dome-shaped cavity.
Aufgrund der Verwendung eines Formfräsers ist die Kavität zwangsläufig rotationssymmetrisch ausgebildet. Die verwendbaren Prothesenformen werden aufgrund des gegenwärtigen Herstellungsverfahrens für die Kavitäten stark begrenzt. Es kann hierdurch weder funktionell noch individuell eine Optimierung der Prothesen durchgeführt werden.by virtue of the use of a form milling cutter is the cavity inevitably formed rotationally symmetrical. The usable prosthesis forms be due to the current Manufacturing process for the cavities strongly limited. It can not be functional or individual Optimization of the prostheses are performed.
Bekannt ist ebenfalls bereits die Verwendung sogenannter Chirurgie-Roboter, die eine automatisierte Durchführung von Operationen unterstützen. Die Operationsqualität derartiger Roboter wird jedoch bislang im allgemeinen als unbefriedigend empfunden.Known is already the use of so-called surgery robots, the an automated execution support operations. The operation quality However, such a robot has been generally unsatisfactory felt.
Darüber hinaus sind auch computerunterstützte Operationsverfahren bekannt, bei denen während der Durchführung einer Operation auf einem Monitor dem operierenden Arzt sehr genaue Bildinformationen zum Operationsort zur Verfügung gestellt werden. Es werden hierbei insbesondere zum aktuellen Zeitpunkt vorhandene genaue Positionen des Patienten, der relevanten Körperteile und der Operationsinstrumente dargestellt.Furthermore are also computer assisted Operating procedures are known in which while performing a Operation on a monitor gives the operating doctor very accurate image information to the surgical site available be put. It will be here in particular at the current time Existing exact positions of the patient, the relevant body parts and the surgical instruments presented.
Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung der einleitend genannten Art derart zu konstruieren, daß ein sicherer und zugleich flexibler Einsatz im Bereich der Medizintechnik unterstützt wird.task It is the object of the present invention to provide a device mentioned type to construct such that a safe and at the same time flexible use in the field of medical technology is supported.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Fräskopf zum Ausfräsen einer Knochenkavität für die Aufnahme einer Gelenkprothese ausgebildet ist und daß die Positioniereinrichtung mindestens zwei Bewegungsachsen aufweist.These Task is inventively characterized solved, that the milling head for milling a bone cavity for the Recording a joint prosthesis is formed and that the positioning has at least two axes of movement.
Durch die Ausstattung der Positioniereinrichtung mit mindestens zwei Bewegungsachsen ist es möglich, einen großen Gestaltungsfreiraum bei einem Entwurf von Endoprothesen, insbesondere von Hüftpfannenprothesen, zu erzielen. Durch die erfindungsgemäße beliebige Formgebung für die Kavität ist es möglich, eine Vielzahl unterschiedlicher Prothesenformen zu realisieren. Es ist hierdurch möglich, eine Neugestaltung der Prothesen mit dem Ziel einer Qualitätsverbesserung durchzuführen. Die Qualitätsverbesserung kann beispielsweise in einer schnelleren Wiederherstellung der Beweglichkeit des Patienten oder einer Belastungsteigerung der Prothese im Patienten bestehen oder eine verlängerte Lebensdauer der implantierten Prothese zur Folge haben.By the equipment of the positioning with at least two axes of movement Is it possible, a big Design freedom in a design of endoprostheses, in particular acetabular prostheses, to achieve. By arbitrary shaping of the cavity according to the invention it is possible, to realize a variety of different prosthesis shapes. It is thereby possible, one Redesign of the prostheses with the aim of quality improvement perform. The quality improvement For example, in a faster recovery of mobility of the patient or a load increase of the prosthesis in the patient persist or an extended one Life of the implanted prosthesis result.
Aufgrund der mehreren Bewegungsachsen der Positioniereinrichtung ist es möglich, Pendelbewegungen des Fräskopfes durchzuführen und hierdurch zum Beispiel Hinterschneidungen zu erzeugen oder krafteinleitungsoptimierte Kavitäten zu generieren. Ebenfalls besteht eine Anwendungsmöglichkeit in der Herstellung von Entlastungsnuten.by virtue of the multiple axes of movement of the positioning it is possible to oscillate of the milling head perform and thereby, for example, to create undercuts or force introduction optimized wells to generate. There is also an application in the production of relief grooves.
Erfindungsgemäß ist es insbesondere auch möglich, Fräswerkzeuge aus dem Bereich der Mikrotechnologie zu verwenden und hierdurch eine weitere Optimierung des Fräsvorganges durchzuführen. Eine Anwendung kann sowohl bei der Implantation von zementierten als auch von zementfreien Prothesen erfolgen.It is according to the invention especially possible, milling tools to use in the field of microtechnology and thereby a further optimization of the milling process perform. A Application can be cemented both in the implantation of also carried out by cementless prostheses.
Eine besonders große Flexibilität bei der Formgebung der Kavität läßt sich dadurch erreichen, daß die Positioniereinrichtung zur Durchführung eines Viel-Achs-Fräsens ausgebildet ist.A especially big flexibility in the shaping of the cavity let yourself achieve that the Positioning device designed to carry out a multi-axis milling is.
Ein bevorzugtes Anwendungsgebiet beseht darin, daß die Positioniereinrichtung zur Herstellung von Hüftpfannenprothesenkavitäten ausgebildet ist.One preferred field of application is that the positioning device designed for the production of acetabular prosthesis cavities is.
Eine Verwendung von Standardkomponenten wird dadurch unterstützt, daß die Positioniereinrichtung als ein Industrieroboter ausgebildet ist.A Use of standard components is supported by the positioning device is designed as an industrial robot.
Als besonders vorteilhaft erweist es sich, daß die Positioniereinrichtung als ein 6-Achsen-Roboter ausgebildet ist.When Particularly advantageous turns out that the positioning is designed as a 6-axis robot.
