Description

Die Erfindung soll das bisher bekannte Verfahren der Nagelentfernung durch Schläge mit einem durch iNtuskelkraft bedienten Hammer ersetzen. Seine Anwendung ist für den Operateur oft mit einer schwierigen und zeitraubenden Arbeit verlunden und führt mitunter nicht zu dem gewünschten Erfolg. Für den Patienten entsteht hierdurch die Gefahr schwerer Komplikationen. The invention aims at the previously known method of nail removal replace with blows with a hammer operated by muscle strength. Its application is often lost with difficult and time-consuming work for the surgeon and sometimes does not lead to the desired success. This creates for the patient the risk of serious complications.

Der Erfindung liegt der Gedanke zugrunde, daß schnelle, durch mechanische, hydraulische oder elektrische Energie erzeugte Schläge auf eine Zugstange den Sitz des Nagels im Knochen lockern. The invention is based on the idea that fast, mechanical, Hydraulic or electrical energy generated blows on a pull rod to the seat loosen the nail in the bone.

Durch den stetigen Zug, der im Gegensatz zu den lisherigen Geräten immer in Achsrichtung erfolgen kann, in Verbindung mit der Schlagarbeit wird der Nagel herausgezogen. Das Verfahren entspricht dem bereits bekannten bei Druckluft und ähnlichen NVerkzeugen, nur ist die Kraft- bzw. Arbeitsrichtung umgekehrt.Due to the constant train, which in contrast to the previous devices can always take place in the axial direction, in connection with the impact work the Nail pulled out. The process corresponds to that already known for compressed air and similar N tools, only the direction of force or work is reversed.

Die Skizze stellt ein Gerät zur Ausführung der oben l)eschriel)ellen Funktionen dar, und zwar mit Druckluftbetrieb. Die Wirkungsweise ist folgende: Die im Gehäuse geführte Zugstange a, das Kraftübertragungsglied, kann sich nur in der Schlagrichtung, d. h. nach oben bewegen. Der Bund auf der Stange leitet die Zugkräfte vom Gehäuse über die Zugstange auf den zu entfernenden Nagel. Das obere Ende der Stange trägt einen Kolben, der gleichzeitig zur Bildung des Druckraumes d sowie zur Aufnahme der Schlagenergie dient. Die Schlagarbeit selbst wird durch die Druckluft geleistet. The sketch represents a device for carrying out the above l) eschriel) ellen Functions, with compressed air operation. The mode of action is as follows: The in the housing guided pull rod a, the power transmission link, can only be in the Direction of lay, d. H. move up. The collar on the rod conducts the tensile forces from the housing via the pull rod to the nail to be removed. The top of the Rod carries a piston, which at the same time to the formation of the pressure chamber d as well serves to absorb the impact energy. The impact work itself is done by the compressed air done.

Der Vorgang ist folgender: Die Druckluft gelangt über die Verbindungsbohrung h im Gehäuse und den Ringkanal am Schlagzylinder b an die Unterseite des Kolbenschiebers c und hebt diesen an. Nun tritt die Luft durch die frei gewordene Bohrung i über einen weiteren ringförmigen Raum im Gehäuse und Bohrungen im Schlagzylinder b in den Druckraum d. Hier treibt die Druckluft den Zylinder nach oben, bis dieser an die Unterseite des Kolbens an der Zugstange anschlägt und an dieser Stelle die Schlagarl)eit leistet. In dieser oberen Lage des Schlagzylinders wird durch einen zweiten Ringraum am Schlagzylinder und die Bohrung k im Gehäuse auf die Oberseite des Kolbenschiebers c Druckluft geführt, so daß nun letzterer druckentlastet und durch die Feder j in seine Anfangsstellung zurückgeschoben wird. Nunmehr kann die Luft durch den Austrittskanal entweichen, so daß die Feder e den Schlagzylinder b ebenfalls zurückbewegen kann. Jetzt kann der Vorgang von neuem beginnen. Der gleichmäßig ausgeübte Zug wird durch den Handgriff g cingeleitet. The process is as follows: The compressed air reaches the connecting hole h in the housing and the ring channel on the impact cylinder b on the underside of the piston valve c and lifts it up. The air now passes through the hole i that has become free another annular space in the housing and bores in the impact cylinder b in the pressure chamber d. Here the compressed air drives the cylinder upwards until it is activated the underside of the piston hits the pull rod and at this point the stroke length perform. In this upper position of the impact cylinder is through a second annular space on the percussion cylinder and the bore k in the housing on the top of the piston valve c compressed air out, so that the latter is now depressurized and by the spring j in its initial position is pushed back. The air can now pass through the outlet duct escape so that the spring e can also move the impact cylinder b back. Now the process can begin again. The evenly exerted pull is through the handle is guided.

PATENTANSPROCHE: I. Verfahren zur leichteren Entfernung der bei der Behandlung verletzter oder erkrankter Knochen eingetriel>enen Nägel, dadurch gekennzeichnet, daß auf den Nagel ein gleichmäßiger Zug ausgeübt wird und diesem noch Schlagimpulse überlagert werden. PATENT CLAIM: I. Method for the easier removal of the Treatment of injured or diseased bones penetrated nails, thereby characterized in that an even train is exerted on the nail and this impact pulses are still superimposed.
