Abstract
Description
Die Erfindung betrifft ein motorgetriebenes Frässystem, mit dessen Hilfe Knochenzement aus der Knochenmarkshöhle oder aus anderen Knochenteilen entfernt werden kann. Die Entfernung von Knochenzement ist vorzugsweise in der orthopädischen Chirurgie beim Wechsel oder Ausbau von gelockerten oder infizierten Endoprothesen notwendig. Andere Anwendungen sind zusätzlich möglich.The invention relates to a motor-driven milling system, with whose help bone cement from the bone marrow cavity or from other bone parts can be removed. The removal of Bone cement is preferred in orthopedic surgery when changing or removing loosened or infected ones Endoprostheses necessary. Other applications are additional possible.
Die Zahl der Prothesenwechsel nimmt insbesondere in der Hüft endoprothetik stetig zu. Die Entfernung des Knochenzementes bei zementfixierten Prothesen ist mühsam und zeitaufwendig. Bisher wird die Zemententfernung in der Regel mit verschieden geformten Meißeln durchgeführt, deren sichere Anwendung z. B. in der schlecht einsehbaren Tiefe der Markhöhle problematisch ist. Es können neben dem hohen Zeitaufwand Knochenschädigungen resultieren, die die Neuimplantation einer Prothese unmöglich machen oder aber zu einem übergroßen Knochenverlust führen.The number of prosthesis changes increases especially in the hip endoprosthetics steadily. The removal of the bone cement with cement-fixed prostheses is tedious and time-consuming. So far, the cement removal is usually different shaped chisels performed, the safe use of z. B. problematic in the poorly visible depth of the medullary cavity is. In addition to the high expenditure of time, bone damage can occur result in impossible re-implantation of a prosthesis make or lead to excessive bone loss.
Aus der Werkzeugüberwachung bei Zerspanungswerkzeugen ist be kannt, daß mittels Schall-Emissions-Aufnehmern (SEA) die Kör perschallwellen des Werkstückes oder des Werkzeugs gemessen werden können.From tool monitoring for cutting tools, be knows that by means of sound emission sensors (SEA) the Kör sound waves of the workpiece or tool are measured can be.
Mit dem dargestellten Frässystem ist zunächst eine Zerkleinerung und Absaugung des am Knochen noch anhaftenden Knochenzementes möglich. Die Konstruktion der Fräsköpfe in Hülsen mit unterschiedlicher Fräsöffnung ermöglicht bereits eine gezieltere Anwendung der Fräsen.With the milling system shown, there is initially one Crushing and suctioning off the bone that still adheres to the bone Bone cement possible. The design of the milling heads in Sleeves with different milling openings already allow a more targeted application of milling.
Beim motorgetriebenen Fräsen von Knochen bzw. Knochenzement werden ebenfalls Körperschallwellen erzeugt. Diese Körper- Schallwellen zeigen für Knochen und Knochenzement eine un terschiedliche Intensität, die bereits mit handelsüblichen SEA meßtechnisch erfaßt werden können.For motor-driven milling of bones or bone cement structure-borne sound waves are also generated. This body Sound waves show an un for bones and bone cement different intensity, which is already available with commercially available SEA can be measured.
Durch die Steuerung über den meßbaren Körperschall kann beim Fräsen, z. B. auch in der schlecht einsehbaren Tiefe des Mark raumes, sicher zwischen dem Fräsen am Knochen oder am Knochen zement unterschieden werden. Durch geeignete Sichtbarmachung der Schallintensität und/oder akustische Warnsignale und/oder automatische Abstellung des motorgetriebenen Frässystems beim Knochenkontakt ist eine sichere Entfernung des Zementes möglich.By controlling the measurable structure-borne noise, the Milling, e.g. B. also in the poorly visible depth of the marrow space between the milling on the bone or on the bone cement can be distinguished. Through suitable visualization the sound intensity and / or acoustic warning signals and / or automatic shutdown of the motorized milling system at Bone contact is a safe removal of the cement possible.
Der Zeitaufwand zur Zemententfernung, vorzugsweise am Beispiel des Prothesenwechsels, wird deutlich reduziert. Eine Zemententfernung ist ohne wesentliche Schädigung des Knochens auch im nicht einsehbaren Bereich möglich.The time required for cement removal, preferably using the example prosthesis change is significantly reduced. A Cement removal is without significant damage to the bone also possible in the non-visible area.
Das in der Erfindung beschriebene Frässystem ist jedesmal anwendbar, wenn am Knochen anhaftender Knochenzement entfernt werden muß. Die Anwendung dieses Systems ist daher in allen orthopädisch-chirurgischen Abteilungen denkbar.The milling system described in the invention is every time applicable when bone cement adhering to the bone is removed must become. The application of this system is therefore in all orthopedic-surgical departments conceivable.
Ein Ausführungsbeispiel ist in den Abbildungen dargestellt und wird im folgenden näher beschrieben:An embodiment is shown in the figures and is described in more detail below:
Abb. 1 zeigt Ausführungsbeispiele unterschiedlich ge stalteter Fräsen, die bereits ein gezielteres Fräsen von Knochenzement unter Schonung von Knochen ermöglichen. Eine Führungshülse 1 ist in unterschiedlicher Weise derart geöffnet 2 daß der Fräskopf 3 nur in eine bestimmte Richtung fräsen kann. In der Führungshülse 1 der Fräse ist eine Absaugvorrichtung in geeigneter Weise installiert, ggf. auch eine Spülvorrichtung. Die Spülflüssigkeit kann jedoch auch über eine getrennte Vorrichtung an den Fräskopf herangeführt werden. Auch ein Einsatz des Fräskopfes ohne integrierte Saug-Spülvorrichtung ist denkbar. Fig. 1 shows exemplary embodiments of differently designed milling cutters, which already enable a more targeted milling of bone cement while protecting bones. A guide sleeve 1 is opened in different ways 2 such that the milling head 3 can only mill in a certain direction. A suction device is suitably installed in the guide sleeve 1 of the milling machine, and possibly also a flushing device. However, the rinsing liquid can also be brought to the milling head via a separate device. It is also conceivable to use the milling head without an integrated suction-flushing device.
Abb. 2 zeigt ein Ausführungsbeispiel für die Halterung 4 eines handelsüblichen Schall-Emissions-Aufnehmers 5, der von Hand am intraoperativ sichtbaren körpernahen Knochenanteil fixiert werden kann. Andere Fixationsmöglichkeiten des SEA am Knochen, z. B. durch Schraube oder Cerclage sind möglich. Fig. 2 shows an embodiment for the holder 4 of a commercially available sound emission transducer 5 , which can be fixed by hand on the intraoperatively visible body part of the bone. Other fixation options of the SEA on the bone, e.g. B. by screw or cerclage are possible.
