"Vorrichtung, bestehend aus einem hohlen Knochennagel und einer mit diesem verbundenen Hüftgelenkprothese" "Device consisting of a hollow bone nail and a hip joint prosthesis connected to it"

Die Erfindung bezieht sich auf eine Vorrichtung, bestehend aus einem hohlen Knochennagel und einer mit diesem verbundenen HUftgelenkprothese.The invention relates to a device consisting of a hollow bone nail and one connected to it Hip joint prosthesis.

Eine solche Vorrichtung wird beispielsweise verwendet, wenn ein Patient ein künstliches Hüftgelenk benötigt und wenn zugleich bei ihm ein Oberschenkelbruch geheilt werden muß.Such a device is used, for example, when a patient needs an artificial hip joint and when at the same time he has a thigh fracture to be healed.

Bisher hat sich in solchen Fällen der Arzt so geholfen, daß er eine Prothese und einen Nagel ausgewählt hat, die möglichst gut zueinander passten, wobei dann aber stets die Prothese etwas relativ zu dem Nagel gekippt werden konnte. Hinzu kommt, daß der Spieß, der vor dem Aufbohren des Knochens in diesen eingezogen wird und die Aufgabe hat, eine Führung für das Bohrwerkzeug zu bilden, vor dem Einsatz der Prothese entfernt werden muß. Das wiederum hat zur Folge, daß das Einsetzen der Prothese in den Nagel Probleme auf wirft.So far, in such cases, the doctor has helped himself by choosing a prosthesis and a nail, which are as close as possible fit together well, but then the prosthesis could always be tilted somewhat relative to the nail. Come in addition, that the skewer, which is drawn into the bone before the drilling and has the task of guiding the drilling tool to form, must be removed before inserting the prosthesis. This in turn has the consequence that the insertion of the prosthesis raises problems in the nail.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs erwähnte Vorrichtung derart auszubilden, daß die Operation ohne Schwierigkeiten durchführbar ist und nach der Operation eine einwandfreie Verbindung zwischen Prothese und Nagel besteht.The invention is based on the object of designing the device mentioned at the beginning in such a way that the operation can be carried out without difficulties feasible and perfect after the operation There is a connection between the prosthesis and the nail.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Verbindung zwischen Prothese und Nagel steif ist und daß sich in der Prothese eine Längsbohrung befindet.According to the invention, this object is achieved in that the connection between the prosthesis and the nail is stiff and that there is a longitudinal bore in the prosthesis.

Die Längsbohrung ermöglicht es, die Prothese über den Führungsspieß in den Knochen einzuführen, vas das Einsetzen der Prothese erleichtert. Der Spieß wird anschliessend erst herausgezogen. The longitudinal bore allows the prosthesis to be placed over the guide wire to be inserted into the bone, which facilitates the insertion of the prosthesis. The skewer is only then pulled out.

Die Verbindung zwischen Nagel und Prothese kann für den Arzt unlösbar oder lösbar sein. Ist sie lösbar, kann sie ohne weiteres lösbar sein (z.B. ist die Prothese in den Nagel lediglich einsteckbar ausgebildet) oder solcher Art lösbar sein, daß erst ein Teil aus einer ersten Stellung in eine zweite Stellung gebracht werden muß (z.B. ist die Prothese in den Nagel einschraubbar ausgebildet). Der letztere Fall hat den Vorteil, daß man den Nagel mit der Prothese aus dem Knochen herausziehen kann.The connection between nail and prosthesis can be inseparable or detachable for the doctor. If it is solvable, it can easily be detachable (e.g. the prosthesis can only be inserted into the nail) or be detachable in such a way that only one Part has to be moved from a first position to a second position (e.g. the prosthesis is designed to be screwable into the nail). The latter case has the advantage that the nail with the prosthesis can be pulled out of the bone.

Weitere Einzelheiten der Erfindung ergeben sich aus der einzigen Figur der Zeichnung.Further details of the invention emerge from the single figure of the drawing.

Darin ist mit 1 ein Knochennagel, mit 2 eine Prothese, mit 3 ein Gewinde zwischen Nagel 2 und Prothese 2 und mit 4 eiis Längsbohrung in der Prothese 2 bezeichnet.There is a bone nail with 1, a prosthesis with 2, and with 3 a thread between nail 2 and prosthesis 2 and with 4 longitudinal holes referred to in the prosthesis 2.
