Abstract
Description
Die Erfindung betrifft ein Sägeblatt für eine chirurgische Säge mit einem oszillierenden Drehantrieb mit einer konzentrisch zur Drehachse des Sägeblattes verlaufenden Schneidkante, längs welcher Schneidzähne angeordnet sind, wobei im Zahngrund zwischen benachbarten Schneidzähnen Durchbrechungen vorgesehen sind.The invention relates to a saw blade for a surgical Saw with an oscillating rotary drive with a concentric to the axis of rotation of the saw blade running cutting edge, lengthways what cutting teeth are arranged, with openings in the tooth base between adjacent cutting teeth are provided.

Aus der
Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, bei einem gattungsgemäßen Sägeblatt die Spanabfuhr im Bereich der Schneidzähne zu verbessern.Based on this state of the art it is the object of the invention in a generic saw blade to improve chip evacuation in the area of the cutting teeth.
Diese Aufgabe wird bei einem Sägeblatt der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß der Schnittpunkt der seitlichen Schneidzahnbegrenzungen innerhalb der Durchbrechungen liegt. Die seitlichen Schneidzahnbegrenzungen laufen also in Richtung auf die Schneidkante auseinander, so daß sich der Zwischenraum zwischen den Schneidzähnen verbreitert, dies führt zu einer Verbesserung der Spanabfuhr.This task is done with a saw blade of the type described in the introduction solved in that the intersection the lateral cutting tooth limits within the openings lies. The lateral cutting tooth boundaries therefore run in the direction apart on the cutting edge, so that the space between the cutting teeth widened, this leads to improve chip evacuation.
Die Durchbrechungen können geschlossen sein, es ist aber gemäß einer bevorzugten Ausführungsform auch vorgesehen, daß die Durchbrechungen zum Zwischenraum zwischen benachbarten Zähnen hin offen sind. Auf diese Weise können in den Durchbrechungen aufgenommene Späne in den Zwischenraum zwischen den Zähnen abgegeben werden oder umgekehrt aus diesem Zwischenraum in die Durchbrechungen eintreten und von dort abgeführt werden.The openings can be closed but it is according to one preferred embodiment also provided that the Openings towards the space between adjacent teeth are open. That way you can chips in the openings in the space between teeth are released or vice versa from this space into the openings enter and be removed from there become.
Günstig ist es, wenn die Öffnung der Durchbrechung zum Zwischenraum hin schmal ist gegenüber der Breite der Durchbrechungen.Cheap it is when the opening the opening to the gap is narrow compared to the Width of the openings.
Die Durchbrechungen können grundsätzlich unterschiedliche Querschnitte aufweisen, besonders bevorzugt werden Durchbrechungen mit einem kreisförmigen Querschnitt.The openings can be fundamentally different Have cross sections, openings are particularly preferred with a circular Cross-section.
Vorzugsweise liegt der Schnittpunkt der seitlichen Schneidzahnbegrenzungen im vorderen Bereich der Durchbrechungen, beispielsweise ist dieser Schnittpunkt zwischen 20 und 40% des Durchbrechungsradius von dessen Rand entfernt.The intersection is preferably located the lateral cutting tooth limits in the front area of the openings, for example, this intersection is between 20 and 40% of the breakthrough radius from its edge.
Es ist vorteilhaft, wenn der größte Durchmesser der Durchbrechung zwischen 40 und 70 % der Schneizahnbreite beträgt, so daß genügend Material zwischen den Durchbrechungen bleibt, um eine sichere Verbindung der Schneidzähne mit dem übrigen Sägeblatt zu gewährleisten.It is advantageous if the largest diameter the opening is between 40 and 70% of the width of the cutting teeth, so that enough material between the openings remain to ensure a secure connection of the cutting teeth the rest of the saw blade to ensure.
Die beschriebenen Durchbrechungen arbeiten besonders vorteilhaft in Kombination mit Schneidzähnen, die wechselweise in entgegengesetzter Richtung geschränkt sind.The breakthroughs described work particularly advantageously in combination with cutting teeth are alternately constrained in the opposite direction.
Eine besonders gute Wirkung erhält man hinsichtlich der Spanabfuhr bei Schneidzähnen, die einen Diamantschliff aufweisen.A particularly good effect is obtained with regard to chip evacuation from cutting teeth, which have a diamond cut.
Die nachfolgende Beschreibung bevorzugter Ausführungen der Erfindung dient im Zusammenhang mit der Zeichnung der näheren Erläuterung. Es zeigen:The following description of preferred versions the invention serves in conjunction with the drawing for a more detailed explanation. Show it:
