Gekrümmter KnochennagelCurved bone nail
Die Erfindung betrifft einen gekrümmten Knochennagel .,um Ausrichten der gebrochenen Knochenteile von menschlichen Oberschenkeln im proximalen Bereich, wonach der distale Bereich mit einer aus dem Knochen herausragenden Abflachung verahen ist ο Gekennzeichnet ist das Erfundene dadurch, dass die Abflachung eine das Profil des Hagels kreisrunden Querschnittes unterbrechende Quetschplatte ist.The invention relates to a curved bone nail. To Aligning the broken bones of human thighs in the proximal area, after which the distal Area with a flattening protruding from the bone is ο What has been invented is characterized by that the flattening is a pinch plate interrupting the profile of the hail with a circular cross-section is.
Dies ausgehend vom Bekannten nach OS 2 341 439· Bei dessen Formgestaltung des freien Nagelendes dient die Abflachung anscheinend dazu, den Nagel drehen zu können. Zu diesem Zweck ist eine Art Verdreheisen vorgesehen, das den Schraubenschlüsseln ir\ den Mechanikerwerkstätten entspricht. Damit der Knochennagel auch wieder aus de^ Knochen herausgeschlagen werden kann, wird ein zweites Eisen oenötigt, von dem ein Zr.hn in einen Schlitz im freien, abgeplatteten Ende des Nagels hineinschwenkbar ist, um am Sohlageisen den Hammer angreifen zu lassen. Nun sind Knochennägel dünn. Infolgedessen wird der Schlitz in der Abflachung schmal sein müssen. Dies bedeutet, dassThis is based on the acquaintance according to OS 2 341 439 · The flattening is used for the design of the free nail end apparently to be able to twist the nail. A kind of twisting iron is provided for this purpose, the wrenches in the mechanic's workshops is equivalent to. So that the bone nail can be knocked out of the bone again, a second one is needed Iron is required, one of which is inserted into a slot in the free, flattened end of the nail can be swiveled in to allow the hammer to attack the sole iron. Now bone nails are thin. As a result, the slot in the flat will have to be narrow. This means, that
a) beim Bekannten das Einarbeiten des Schlitzes in den Nagel teuer sein wird, dassa) with acquaintances, making the slot in the nail will be expensive that
7519605 05.0Z767519605 05.0Z76
b) das durch das schlitzförmige Loch geschwächte Nagelende stark bruchgefährdet ist und das3b) the end of the nail weakened by the slit-shaped hole is in high risk of breakage and the 3
c) der Schlitz das den menschlichen Knochen umgebende Gewebe reizen kann·c) the slot can irritate the tissue surrounding the human bone
Alle diese Mangel sind dem Erfindungsgegenstand nicht anhängbar.All of these defects are not part of the subject matter of the invention attachable.
Aber auch das Verdrehwerkzeug findet einen sicheren Halt an der Quetschplatte. Es ist zudem auch als Nagelheraa3-schlagwerkzeug verwendbar, so dass ein Werkzeug gespart wird. Der schlitzlose Nagel verspricht demnach erhebliche Vorteile gegenüber dem Bekannten hinsichtlich Herstellung, Handhabung und Patientenverträglichkeit·But the twisting tool also finds a secure hold on the squeeze plate. It can also be used as a nail hammer usable, so that one tool is saved. The slotless nail therefore promises considerable Advantages over the known in terms of production, handling and patient tolerance
Die Zeiciinung zei-jt ein Ausführungsbeispiel gemässThe drawing shows an embodiment according to
Pig 1 im Aufriss und gemässPig 1 in elevation and according to
Pis 2 in einer Seitenansicht. DiePis 2 in a side view. the
Fig 3 stellt die Stirnansicht des Uagelendes nach. Pfeil S in Pig 1 dar, Fig. 3 reproduces the end view of the Uagelende. Arrow S in Pig 1 ,
woraus ersichtlich ist, dass der Schlüsselkopf die Quetschplatte 2 des Nagels 1 leicht erfassen kann. Dies wegen der optimalen Zentrierung bzwe "Aufnahme" des Wekrzeugkopfes zum Zweck des Drehens und des axialen Bewegens des Nagels· from which it can be seen that the wrench head can easily grasp the pinch plate 2 of the nail 1. This is due to the optimum centering or e "picture" of the Wekrzeugkopfes for the purpose of rotating and axially moving the nail ·
