Abstract

The fractured bone fixing pin is formed in two parts, these being pref. screwed together. One part is formed of steel to provide a drill bit the other part being formed of an alloy. The second part forms the fixing pin proper and remains in the bone after separation from the drill bit portion. The pin pref. includes a protective plug which replaces the drill but after it has been removed from the pin proper. The pin proper pref. includes a drain orifice ensuring its penetration.

Description

In der chirurgischen Behandlung des Knochengenjstes, In the surgical treatment of the bone junction,

insb. bei der åusserlichen Behandlung von Knochenbrflchen, werden sog. transcutane Nägel oder ',teinmannsche Nagel verwendet, die durch Fleisch und Knochen hindurch eingesetzt werden.especially in the external treatment of broken bones so-called transcutane nails or ', teinmannsche nails used by meat and Bones are inserted through.

Dies setzt eine entsprechende vorherige Bohrung des Knochens voraus. This requires a corresponding previous drilling of the bone.

Zu diesem Zweck hat man bereits vorgeschlagen, die Nägel so auszubilden, dass ihr Kopf als Bohrer dienen kann, sodass beim Einsetzen der Nagel selbst die Bohrung des Knochenloches vornimmt. Mit Steinmannschen Nägeln, die eine Spitze aufweisen, kann dieses Bohren durch Drehen oder sogar durch Transcutaner Nagel zur Verankerung von Knochenlreristteilen Einschlzsgen des NAgels stattfinden. For this purpose it has already been proposed to design the nails in such a way that that their head can serve as a drill, so that when inserting the nail itself the Drilling the bone hole makes. With Steinmann nails that have a point, this drilling can be done by turning or even by transcutaneous nail for anchoring of leftover bones Impacts of the nail take place.

Die Praxis hat nun gezeigt, dass die zur Ausführung solcher Nägel bernitzten besonderen Legierungen sich für die Ausbildung eines wirksamen Bohrerkopfes nicht eignen. Practice has now shown that it is necessary to execute such nails Special alloys were used to form an effective drill head not suitable.

Der beste Bohrer wäre der übliche im Handel befindliche Stahlbohrer, dessen Legierung sich aber für den betreffenden Zweck nicht eignet. The best drill would be the standard steel drill available on the market, but its alloy is not suitable for the purpose in question.

Gegenstand vorliegender Erfindung ist, diese Schwierigkeit zu beseitigen. It is an object of the present invention to overcome this difficulty.

Dieser Zweck wird erfindungsgemäss in der Weise erfüllt, dass man den Nagel aus zwei vorübergehend zusammengesetzten Teilen ausführt, wovon der eine den Bohrer bildet und der andere den im Knochen verbleibende eigentliche Nagel. This purpose is achieved according to the invention in such a way that one executes the nail from two temporarily assembled parts, one of which the drill forms and the other forms the actual nail remaining in the bone.

Die anliegende Zeichnung zeigt eine beispielsweise Ausführungsform des Lrfindungsgegenstandes. The attached drawing shows an exemplary embodiment the subject of the invention.

Die Fig. 1 zeigt den vollständigen aus seinen beiden Teilen zusammengesetzten Nagel. Fig. 1 shows the complete assembled from its two parts Nail.

Die Fig. 2 zeigt die Verbindungsstelle beider Teile im Schnitt und in einem grösseren Masstab. Fig. 2 shows the junction of the two parts in section and on a larger scale.

Die beiden Teile des dargestellten Nagels sind mit 1 und 2 bezeichnet. The two parts of the nail shown are labeled 1 and 2.

Der Teil 1, welcher dazu bestimmt ist im Knochen zu verbleiben, besteht aus einer entsprechend gewählten Legierung, während der Teil 2, der als Bohrer dient aus gut geschliffenem hartem Stahl besteht. Part 1, which is intended to remain in the bone, exists made of an appropriately selected alloy, while part 2, which serves as a drill consists of well-ground hard steel.

Beim Einsetzen des Nagels bohrt der Bohrer 2 das Loch, in welchem der Teil 1 eingeführt wird, wonach man beide Teile 1 und 2 voneinander trennt. When inserting the nail, the drill 2 drills the hole in which Part 1 is introduced, after which you can do both Parts 1 and 2 of each other separates.

Die Verbindung kann irgendwelcher Art sein, z.B. The connection can be of any type, e.g.

wie in Fig. 2 in einem grösseren Masstab dargestellt, kann sie aus einem mit Gewinde versehenen Zapfen 3 bestehen, welcher im eigentlichen Nagel 1 hineingeschraubt ist.as shown in Fig. 2 on a larger scale, it can be made from consist of a threaded pin 3, which in the actual nail 1 is screwed in.

Nach Lösen dieser Verbindung wird man mit Vorzug das im Teil bestehende Loch z.B. mit einem Gewindezapfen ausfüllen, z.B. ein Plastikzapfen, um zu verhindern, dass sich Unsauberketten in diesem Loch ansammeln. After loosening this connection, the existing one in the part is preferred Fill the hole e.g. with a threaded plug, e.g. a plastic plug to prevent that dirty chains accumulate in this hole.

Es kann selbstverständlich jede andere Verbindungsart als eine Verschraubung vorgesehen werden. Man kann z.B. Of course, any other type of connection than a screw connection can be used are provided. One can e.g.

beide Teile miteinander verkleben und die betreffende Stelle mit einem Einschnitt versehen, welcher ein Abbrechen erleichtert.Glue both parts together and the relevant point with a Make an incision, which makes it easier to break off.

Man kann auch den Durchmesser des Teiles 1 ein wenig grösser vorsehen als derselbe des Bohrers 2, oder den Teil 1 mit einem feinen Gewinde versehen, damit er im Knochen mit Sicherheit festgehalten wird. The diameter of part 1 can also be provided a little larger as the same as the drill 2, or the part 1 finely threaded with it it is sure to be held in the bone.
