Aufgabe der Erfindung ist es, eine möglichst einfache, optional einsetzbare und kostengünstig zu fertigende Vorrichtung zur Sensor-Integration für modular aufgebaute intelligente Endoprothesen bereitzustellen, ohne dabei in das Design des Implantates einzugreifen. Dabei ist die einfache intraoperative Handhabung besonders zu berücksichtigen. Bestehende Fertigungs- und Sterilisationsprozesse sollen bei den Implantatherstellern nicht verändert werden.
Die Aufgabe wird durch eine Vorrichtung zur Sensor-Integration für Endoprothesen gelöst, die dadurch gekennzeichnet ist, dass ein Zusatzmodul mit der Form eines zylindrischen, beidseitig geschlossenen Hohlkörpers in vorhandene Öffnungen einer Endoprothese eingesetzt wird. In dem Hohlraum des Zusatzmoduls sind Sensoren und eine Daten-Übertragungseinheit angeordnet. The device for sensor integration is an additional module and is used for endoprostheses.
The object of the invention is to provide a device for sensor integration for modular intelligent endoprostheses that is as simple as possible, usable as an option and cost-effective, without interfering with the design of the implant. Here, the simple intraoperative handling is particularly important. Existing manufacturing and sterilization processes should not be changed by implant manufacturers.
The object is achieved by a device for sensor integration for endoprostheses, which is characterized in that an additional module with the form of a cylindrical, closed on both sides hollow body is inserted into existing openings of an endoprosthesis. In the cavity of the additional module sensors and a data transmission unit are arranged.
Description
Die Vorrichtung zur Sensor-Integration ist ein Zusatzmodul und wird für Endoprothesen angewendet. The device for sensor integration is an additional module and is used for endoprostheses.
Nach der Implantation einer Endoprothese ist ein verbessertes und engmaschiges postoperatives Monitoring für die physiotherapeutische Nachbehandlung und die schnelle Mobilisierung des Patienten von entscheidendem Vorteil. Dieses Monitoring ist über eine Messung der Aktivität des Patienten sowie der Belastung und des Bewegungsumfanges im operierten Gelenk realisierbar. Aussagen zur periprothetischen pH-Wert- bzw. Temperatur-Verschiebung als Indikator für Infektionen im periimplantären Gewebe sind zudem äußerst wertvoll zur frühzeitigen Ergreifung von Gegenmaßnahmen. Bisherige, in der Forschung erprobte, Sensorsysteme können nicht für ein routinemäßiges postoperatives Monitoring im häuslichen Umfeld eingesetzt werden. After the implantation of an endoprosthesis, an improved and close-meshed postoperative monitoring for the physiotherapeutic after-treatment and the rapid mobilization of the patient is of decisive advantage. This monitoring can be realized by measuring the activity of the patient as well as the load and the range of motion in the operated joint. Statements on the periprosthetic pH or temperature shift as an indicator of infections in the peri-implant tissue are also extremely valuable for the early adoption of countermeasures. Previous, field-proven, sensor systems can not be used for routine postoperative monitoring in the home environment.
Die verstärkte Miniaturisierung von Sensoren trägt zu einer immer weitreichenderen potentiellen Anwendung in Endoprothesen bei. In der Vergangenheit wurden verschiedene Sensoren zur Bestimmung des Bewegungsumfanges oder von Gelenkkräften in Endoprothesen vereinzelt integriert. Der Schwerpunkt lag dabei auf der Funktionalität der Sensorik. Die optimale Auslegung einer intelligenten Endoprothese für die breite Anwendung, welche teilweise hohen Belastungen ausgesetzt ist und einer marktfähigen kostengünstigen Fertigung bedarf, wurde bisher nicht berücksichtigt. Aktuelle Designs von intelligenten Endoprothesen-Prototypen erhöhen den Fertigungsaufwand beträchtlich. Auch die Gamma-Sterilisation, welcher jede Endoprothese im bereits verpackten Zustand unterzogen wird, kann zu einer Zerstörung der Sensorik führen. The increased miniaturization of sensors is contributing to an ever more widespread potential application in endoprostheses. In the past, various sensors were used to determine the range of motion or joint forces in endoprostheses. The focus was on the functionality of the sensors. The optimal design of an intelligent endoprosthesis for the broad application, which is sometimes exposed to high loads and marketable cost-effective production requires, has not been considered. Current designs of smart endoprosthesis prototypes increase manufacturing costs considerably. Also, the gamma sterilization, which is subjected to each endoprosthesis in the already packaged state, can lead to destruction of the sensor.
Es gibt Lösungsansätze, bei denen die Sensorik z.B. direkt in den Stiel einer Hüftendoprothese durch Kanalisierung des Implantats integriert wurde, wie beispielsweise in
Eine andere Lösung besteht in einem Zusatzstück, welches an der Spitze eines Hüftstieles angebracht werden soll. Die bisher vorgestellten Implantate gelangten jedoch nicht über den Status Forschung hinaus. Another solution consists in an additional piece which is to be attached to the tip of a hip stem. However, the implants presented so far did not go beyond the status of research.
Bestehende und standardisierte Fertigungsprozesse müssten demnach auf die Fertigung von neuen Endoprothesen optimiert werden, was einen beträchtlichen Kostenaufwand zur Folge hat. Auch beispielsweise das Anfügen eines Zusatzes am distalen Bereich einer Hüftendoprothese ist kritisch zu betrachten, da die genaue Durchführung der Implantation vorher unklar ist. Auch die Auswirkung des Einschlagens von Endoprothesen auf die Sensorik ist noch nicht genügend untersucht. Aus diesem Grund haben es diese Prototypen intelligenter Endoprothesen bis heute nicht zur Marktreife geschafft. Existing and standardized manufacturing processes would therefore have to be optimized for the manufacture of new endoprostheses, resulting in a considerable cost. Also, for example, the addition of an additive to the distal region of a hip endoprosthesis is to be viewed critically, since the exact implementation of the implantation is previously unclear. The effect of the penetration of endoprostheses on the sensors has not been sufficiently investigated. For this reason, these prototypes of smart endoprostheses have not made it to market until today.
Darstellung der Erfindung Presentation of the invention
Aufgabe der Erfindung ist es, eine möglichst einfache, optional einsetzbare und kostengünstig zu fertigende Vorrichtung zur Sensor-Integration für modular aufgebaute intelligente Endoprothesen bereitzustellen, ohne dabei in das Design des Implantates einzugreifen. Dabei ist die einfache intraoperative Handhabung besonders zu berücksichtigen. Bestehende Fertigungs- und Sterilisationsprozesse bei den Implantatherstellern sollen nicht verändert werden. The object of the invention is to provide a device for sensor integration for modular intelligent endoprostheses that is as simple as possible, usable as an option and cost-effective, without interfering with the design of the implant. Here, the simple intraoperative handling is particularly important. Existing manufacturing and sterilization processes at the implant manufacturers should not be changed.
Die Aufgabe wird durch eine Vorrichtung zur Sensor-Integration für Endoprothesen gelöst, die dadurch gekennzeichnet ist, dass ein Zusatzmodul in Form eines zylindrischen, beidseitig geschlossenen Hohlkörpers in vorhandene Öffnungen einer Endoprothese eingesetzt wird. In dem Hohlraum des Zusatzmoduls sind Sensoren und eine Daten-Übertragungseinheit angeordnet. The object is achieved by a device for sensor integration for endoprostheses, which is characterized in that an additional module in the form of a cylindrical, closed on both sides hollow body is inserted into existing openings of an endoprosthesis. In the cavity of the additional module sensors and a data transmission unit are arranged.
Verschiedene Ausführungsformen sind denkbar. So kann das Zusatzmodul die Form einer Hohlschraube haben und in vorhandene Bohrungen mit Gewinde z.B. im proximalen Bereich des Hüftendoprothesen-Stiels eingeschraubt werden. Various embodiments are conceivable. Thus, the additional module may have the form of a hollow screw and into existing threaded holes, e.g. be screwed in the proximal region of the hip endoprosthesis stem.
Für eine andere Ausführungsform ist das Zusatzmodul als Teil eines Verankerungszapfens ausgebildet. For another embodiment, the additional module is formed as part of an anchoring pin.
In dem Zusatzmodul sind verschiedene Sensoren für die Detektion von beispielsweise mechanischen Belastungen, Bewegungsumfängen und/oder Entzündungszuständen an der Endoprothese angeordnet. Als Daten-Übertragungseinheit ist eine Telemetrie- oder eine Funkeinheit angeordnet. Die Messwert-Übertragungseinheit ist mit einer externen Auswerteeinheit verbunden, wobei die Daten drahtlos übertragen werden. In the additional module, various sensors for the detection of, for example, mechanical loads, movement circumferences and / or inflammatory conditions are arranged on the endoprosthesis. As a data transmission unit, a telemetry or a radio unit is arranged. The measured value transmission unit is connected to an external evaluation unit, the data being transmitted wirelessly.
Die erfindungsgemäße Vorrichtung kann als sehr einfaches Zusatzmodul an die Endoprothese angeschraubt werden. Dabei steht es jedem Operateur offen, ob er oder sie die Sensorik in das Implantat einbaut oder nicht. Von großem Vorteil ist hierbei, dass beispielsweise die meisten Hüftendoprothesen im proximalen Hüftstiel über ein Gewinde verfügen. Das Gewinde wird normalerweise für das Einsetzen und den Auszug der Implantate verwendet. Damit werden an dem Hüftstiel keine Veränderungen vorgenommen. Das Schraubmodul ist optional einsetzbar. The device according to the invention can be screwed to the endoprosthesis as a very simple additional module. It is open to any surgeon whether he or she incorporates the sensors into the implant or not. Of great advantage here is that, for example, most hip endoprostheses in the proximal hip stem have a thread. The thread is normally used for insertion and removal of the implants. This will be on the hip stem no changes performed. The tightening module can be used optionally.
Die Vorrichtung mit den integrierten Sensoren trägt wesentlich zu einem verbesserten postoperativen Monitoring (Messung der Aktivität des Patienten und der Beanspruchung der Implantats-Implantatbelastung) bei und stellt dabei eine sehr einfache Möglichkeit dar, intraoperativ die Sensorik in das Implantat optional nach dessen Einsetzen zu integrieren. The device with the integrated sensors contributes significantly to an improved postoperative monitoring (measurement of the activity of the patient and the stress on the implant-implant loading) and thereby represents a very simple possibility to intraoperatively integrate the sensors into the implant optionally after its insertion.
Die Fertigung der erfindungsgemäßen Vorrichtung in einem eigenen Prozess, ohne die Endoprothese im Wesentlichen zu beeinflussen und die einfache intraoperative Handhabung der Vorrichtung, stellt einen grundlegenden Vorteil im Vergleich zu anderen Lösungsansätzen dar. Der Fertigungsprozess dieses Zusatzmoduls ist zudem nicht von den standardisierten Prozessen der Endoprothesenfertigung abhängig. Zusätzliche kostenaufwändige Zulassungsprozesse an der Endoprothese selbst werden somit vermieden. The production of the device according to the invention in a separate process, without substantially affecting the endoprosthesis and the simple intraoperative handling of the device, represents a fundamental advantage compared to other approaches. The manufacturing process of this additional module is also not dependent on the standardized processes of Endoprothesenfertigung , Additional costly approval processes on the endoprosthesis itself are thus avoided.
Mit diesem Bauteil, welches als Zusatz je nach Bedarf eingebaut werden kann, müssen vorhandene Fertigungs- und Sterilisationsprozesse bei Implantatherstellern nicht verändert werden. Die Vorrichtung ist unabhängig von Sterilisationsprozessen der Endprothese, welche die Elektronik schädigen würden. Diese kann mittels handelsüblichen Plasmaverfahren erfolgen. With this component, which can be installed as an addition according to requirements, existing manufacturing and sterilization processes at implant manufacturers need not be changed. The device is independent of sterilization processes of the final prosthesis, which would damage the electronics. This can be done by means of commercial plasma processes.
