Description
Anwendungsgebiet der ErfindungField of application of the invention
Die Erfindung betrifft eine neuartige Ratsche für die Anwendung in der Medizinaltechnik, insbesondere der Dentalprothetik. Die Zuverlässigkeit von Verschraubungen bedingt eine genaue Einhaltung von Vorgaben für Vorspannkräfte via dem Drehmoment. Hierfür wird ein Drehmomentschlüssel benutzt, der in der Regel zur besseren Handhabung bei beengten Platzverhältnissen mit einer Ratsche versehen ist. Eine Ratsche ermöglicht in bekannter Weise das Anziehen einer Verschraubung in möglichst kleinen Winkelschritten des Schlüssels. Sie überträgt die Schwenkbewegung eines Hebels in nur einer Richtung, während die andere Richtung gesperrt ist.The The invention relates to a novel ratchet for use in medical technology, especially dental prosthetics. The reliability of glands requires a strict adherence to specifications for prestressing forces via the torque. Therefor becomes a torque wrench used, which is usually for better handling in confined spaces provided with a ratchet. A ratchet allows in a known manner the Tightening a screw connection in the smallest possible angular steps of the key. It transfers the pivoting movement a lever in one direction while the other direction is locked is.
In der Regel bestehen Ratschen aus mehreren Teilen, Ratschenkörper, Federelement, Schlüsselhalter, Ratschrad, Ratschkopf, Fixierstifte, ggfs. mehr. Für eine nötige Sterilisation müssen alle Teile demontiert, sterilisiert und wieder zusammengesetzt werden.In Ratchets usually consist of several parts, ratchet body, spring element, Key holder, Ratchet wheel, ratchet head, fixing pins, if necessary more. For a necessary sterilization have to All parts are disassembled, sterilized and reassembled.

Aufgabe der ErfindungObject of the invention
Aufgabe der Erfindung ist eine wesentliche Vereinfachung der Ratsche, um bei verringertem Aufwand für Demontage und Wegfall der Wiedermontage (Zeitersparnis) eine einfachere Reinigung und Sterilisation zu erreichen.task The invention is a substantial simplification of the ratchet to at a reduced cost for Disassembly and removal of reassembly (time saving) a simpler To achieve cleaning and sterilization.
Die Ratschenfunktion soll nicht durch Verklemmen des Klinkensegments arbeiten.The Ratchet function should not by jamming the latch segment work.
Die Handhabbarkeit bei den beengten Platzverhältnissen bleibt eine wichtige Forderung an das Gerät.The Handling in confined spaces remains an important Demand to the device.
Wichtiges Ziel der Erfindung ist es, Herstellkosten zu reduzieren.Important The aim of the invention is to reduce manufacturing costs.
Die Ratschenfunktion muss auch in dahingehend ungünstiger Umgebung immer gewährleistet sein und das Ergebnis von z.B. eines dahinter geschalteten Drehmoment-Biegeastes nicht verfälschen.The Ratchet function must always be guaranteed even in unfavorable environment and the result of e.g. behind a connected torque bending eyelet do not falsify.
Beschreibung der ErfindungDescription of the invention
Die Erfindung betrifft eine Ratsche, die nur aus einem Teil besteht, ein Mono-Ratschenkopf.The Invention relates to a ratchet, which consists of only one part, a mono ratchet head.
Dieser
Mono-Ratschenkopf kann in einen zum Anziehen einer Schraube geeigneten
Schlüssel integriert
werden, indem der Anschluss des Mono-Ratschenkopfs (
Dieser Handhebel kann als Biegebalken mit integriertem Drehmomentaufnehmer ausgebildet sein.This Hand lever can be used as a bending beam with integrated torque transducer be educated.
Die
Federung des aus dem inneren Umfang des Mono-Ratschenkopfes herausgearbeiteten
Klinkensegments (
Bekannte
Eindrehwerkzeuge weisen in der Regel achsparallele Furchen im Rätschrad
(
Die Erfindung zeichnet sich dadurch aus, dass die Funktionen „Halten des Eindrehwerkzeugs", „Führen des Eindrehwerkzeugs" und „Drehen des Eindrehwerkzeugs" in einem Element integriert sind.The Invention is characterized in that the functions "Hold of the driving tool "," guiding the Inserting tool "and" turning of the screwing tool "in integrated into an element.
Das
Klinkensegment (
Das
Klinkensegment klemmt nicht das Rätschrad, sondern es drückt auf

(
Der Mono-Ratschenkopf ist klein, es gibt keine äusseren scharfen Kanten.Of the Mono ratchet head is small, there are no outer sharp edges.
Das kleine Bauvolumen ermöglicht den Einsatz des Mono-Ratschenkopfes bei sehr begrenzten räumlichen Verhältnissen.The small construction volume allows the use of the mono-ratchet head in very limited spatial Conditions.
Der einteilige Ratschenkopf erleichtert die Sterilisation, da keinerlei Demontage oder Wiedermontage nötig ist. Es können Einzelteile weder beschädigt werden noch abhanden kommen. Fehlerquellen werden vermieden. Der Mono-Ratschenkopf muss nicht nach Montageanleitung wieder montiert werden, -Zeitersparnis.Of the one-piece ratchet head facilitates sterilization, since no Disassembly or reassembly necessary is. It can Items neither damaged will still be lost. Sources of error are avoided. Of the Mono ratchet head must not be reassembled according to mounting instructions, -time savings.
Der Mono-Ratschenkopf hat im Sinne einfacher und zuverlässiger Sterilisation keine versteckten Kammern oder Hinterschnitte, die mit besonderer Aufmerksamkeit gereinigt werden müssten.Of the Mono ratchet head has the purpose of simple and reliable sterilization no hidden chambers or undercuts, with special attention would need to be cleaned.
Die Einteiligkeit des Mono-Ratschenkopfes ermöglicht eine wesentliche Reduktion der Fertigungskosten.The Integrity of the mono ratchet head allows a substantial reduction the production costs.
Material und Form des Mono-Ratschenkopfes sind so gewählt, dass die individuelle Handhabung, fortschreitende Oberflächenrauhigkeit, viele Sterilisationszyklen, Ablagerungen oder Korrosion sich nicht fehlerhaft auf die Ratschenfunktion auswirken.material and shape of the mono-ratchet head are chosen so that the individual Handling, progressive surface roughness, many sterilization cycles, Deposits or corrosion are not faulty on the ratchet function impact.
In Verbindung mit einer Drehmomentanzeige, die das entsprechende Signal aus einem hinter den Mono-Ratschenkopf geschalteten Biegebalken erhält, steht ein einteiliger, einfach aufgebauter Drehmomentschlüssel mit Ratsche für medizinische Zwecke zur Verfügung. Hiermit ist zum Beispiel eine Dokumentation der applizierten Drehmomente inklusive -kurven in Echtzeit während der Behandlung/Operation möglich, um die Rückführbarkeit von Montageergebnissen zu sichern.In Connection with a torque indicator showing the corresponding signal from a switched behind the Mono ratchet head bending beam, stands a one-piece, simply constructed torque wrench with Ratchet for medical purposes available. This is, for example, a documentation of the applied torques including -curves in real time during the treatment / operation possible, about traceability to secure assembly results.
