Description

Die bisher bekannten Zughaken für Ziehgeräte zur Entfernung von operativ in Knochen eingetriebenen Nägeln weisen verschiedene Nachteile auf, wie schlechtes Anbringen an den Nagel und Abgleiten beim Ziehvorgang, die durch die besondere Ausführung der neuen Haken vermieden werden sollen. The previously known pull hooks for pulling devices for the removal of surgically Nails driven into bone have various disadvantages, such as bad Attachment to the nail and sliding off during the pulling process, which is due to the special design the new hook should be avoided.

Die Vorrichtung nach der Erfindung besteht aus zudem eigentlichen Haken a zur Ubertragung Ider Zugkraft, dem Sicherungsschieber b und einem Klemmring c. Der Haken ist so ausgebildet, dar er sich leicht in die Öse des Nagels einführen läßt, ohne erst große Bewegungen ausführen zu müssen. Gleichzeitig wird Idurch die besondere Hakenform die Beanspruchung im Hakenquerschnitt herabgesetzt, so daß die bisher häufige Bruch'anfälligkeit vermieden wird. Der Sicherungsschieber mit Xder federnden Öse wird nachträglich aufgesetzt und durch den Klemmring festgehalten. Auf diese Weise wird ein Abgleiten im Betrieb vermieden. The device according to the invention also consists of actual Hook a for transmitting the tensile force, the safety slide b and a clamping ring c. The hook is designed so that it can easily be inserted into the eye of the nail without having to make large movements. At the same time, I become through the special hook shape reduces the stress in the hook cross-section, so that the so far frequent susceptibility to breakage is avoided. The safety slide with Xder The resilient eyelet is subsequently attached and held in place by the clamping ring. In this way, sliding is avoided during operation.

PAT.ENTANSPRilCHE: I. Zughaken für Ziehgeräte zur Entfernung von operativ in Knochen eingetriebenen Nägeln, dadurch gekennzeichnet, daß die untere Krümmung des Hakens (a) so kurz gehalten ist, daß er sich leicht in die Öse des Nagels einführen läßt. CLAIMS: I. Pulling hooks for pulling devices for removing surgically driven nails, characterized in that the lower The curvature of the hook (a) is kept so short that it can easily be inserted into the eye of the Nagels can be introduced.
