Description

Drehmomenten - Ratsche für medizinische ZweckeTorque - Ratchet for medical purposes

BeschreibungDescription

Die Neuerung betrifft eine Verbesserung von Einschraub-Vorrichtungen für Dental - Implantat - und Prothetik l/erschraubungen. The innovation concerns an improvement of screw-in devices for dental implant and prosthetic screw connections.

Um Implantat - und Prothetik -Systeme in der Dental Medizin mit größtmöglicher Zuverlässigkeit einsetzen zu können, schreiben Hersteller für Ihre Systeme optimale Drehmomente vor.In order to be able to use implant and prosthetic systems in dental medicine with the greatest possible reliability, manufacturers specify optimal torques for their systems.

Es sind Momenten - Schraubendreher bekannt, die diese Aufgabe zwar erfüllen, aber dennoch bei gewissen Montage-Behandlungen eine Ratsche wünschenswert oder gar erforderlich machen.There are torque screwdrivers that can fulfill this task, but for certain assembly operations a ratchet is desirable or even necessary.

Die hiermit vorgestellte Drehmomenten-Ratsche mit Doppel-Funktion erfüllt diesen Zweck.The torque ratchet with dual function presented here fulfills this purpose.

Die Neuerung besteht nun darin, daß die Ratsche auf verschiedene erforderliche Drehmomente einstellbar ist.The innovation is that the ratchet can now be adjusted to different required torques.

Auf diese Weise erfüllt die Drehmomenten-Ratsche zwei Funktionen, sowohl als Ratsche wie auch als Überlastsicherung.In this way, the torque ratchet fulfils two functions, both as a ratchet and as an overload protection device.
