Description
Chirurgische Knochensäge mit elektrischem Antrieb Die Erfindung betrifft eine chirurgische Knochensäge mit elektrischem Antrieb, die ein rasches und zuverlässiges Arbeiten und die Führung tiefer und tiefliegender Schnitte in jeder Richtung gestattet und zwecks Reinigung rasch und leicht äuseinandergenommen werden kann.Electric Drive Surgical Bone Saw The invention relates to an electric powered surgical bone saw that is fast and reliable Working and making deep and deep cuts in any direction is permitted and can be disassembled quickly and easily for cleaning.
Dies wird nach der Erfindung dadurch erreicht, daß ein auf einem Halter sitzendes Sägeblatt durch einen Exzenter in Hinundherbewegung versetzt wird. Es sind schon Kreissägen mit elektrischem Antriebe als Knochensägen vorgeschlagen worden, doch versagen diese in vielen Fällen, da man nicht überall damit beikommen kann und auch keine große Schnittiefe sowie kein Arbeiten in der Tiefe möglich ist. Auch wird dabei die Freilegung eines übermäßig großen Teiles des betreffenden Knochens erforderlich, was nunmehr ebenfalls vermieden ist.This is achieved according to the invention in that a on a holder seated saw blade is set in a reciprocating motion by an eccentric. It Circular saws with electric drives have already been proposed as bone saws, but in many cases these fail because they cannot be used everywhere and also no great depth of cut and no working in depth is possible. Even This involves exposing an excessively large part of the bone in question required, which is now also avoided.
Der Gegenstand der Erfindung ist auf der Zeichnung beispielsweise veranschaulicht.The object of the invention is on the drawing, for example illustrated.
Abb. x zeigt eine Ausführungsform der Knochensäge in Seitenansicht, Abb. 2 dieselbe in Vorderansicht.Fig. X shows an embodiment of the bone saw in side view, Fig. 2 the same in front view.
Abb. 3 und 4 stellen ein Sägeblatt derselben mit Halter in Vorderansicht und Seitenansicht dar.Fig. 3 and 4 show a saw blade of the same with holder in a front view and side view.
Abb. 5 und 6 zeigen die Exzenterwelle- in Seitenansicht und im Grundriß.Fig. 5 and 6 show the eccentric shaft in side view and in plan.
Die dargestellte Knochensäge hat zwei sehr dünne Sägeblätter 23 und 24, die an Haltern 25 und 26 sitzen, und zwar seitlich so, caß beim Aneinanderlegen der Halter die beiden Sägeblätter dicht aneinanderliegen, wie aus Abb. z zu ersehen ist. Die Halter 25 und ?6 sind in einem Gehäuse 27, 28 untergebracht und können um einen gemeinsamen Drehzapfen 29, über den sie mit einer Bohrung 3o greifen, eine kleine Schwingbewegung ausführen.The bone saw shown has two very thin saw blades 23 and 24, which sit on holders 25 and 26, sideways like this, caß when they are laid together the holder, the two saw blades lie close to one another, as can be seen in Fig. z is. The holders 25 and 6 are accommodated in a housing 27, 28 and can around a common pivot pin 29, over which they engage with a bore 3o, one perform a small swinging movement.
Hervorgerufen wird diese Schwingbewegung durch eine Exzenterwelle 31 mit zwei um 18o° gegeneinander versetzt angeordneten Exzenterscheiben 32 und 33. Die Exzenter greifen in zugehörige Kurbelschleifen 34 der zugehörigen Sägeblatthalter 26 bzw. 25 ein. Die Exzenterwelle ist in einer Büchse 35 der Gehäusegrundplatte 27 gelagert, die außerdem einen Handgriff 36 trägt.This oscillating movement is caused by an eccentric shaft 31 with two eccentric disks 32 and 32 offset from one another by 180 ° 33. The eccentrics engage in associated crank loops 34 of the associated saw blade holder 26 or 25 a. The eccentric shaft is in a sleeve 35 of the housing base plate 27 stored, which also carries a handle 36.
Der Gehäusedeckel 28, welcher die Halter 25 und 26 umschließt, wird lediglich durch zwei seitliche Klauen 37, die über Stifte 38 der Grundplatte 27 greifen, sowie den Drehzapfen 29, der zu einer Verbindungsschraube ausgebildet ist, mit der Grundplatte 27 verbunden.The housing cover 28, which encloses the holders 25 and 26, is only by two lateral claws 37, which are attached to the base plate 27 via pins 38 grip, as well as the pivot pin 29, which is designed as a connecting screw, connected to the base plate 27.
Auf diese Weise ist ein leichtes und rasches Auseinandernehmen und Reinigen des nur aus wenigen Teilen bestehenden Gerätes möglich und ein ebenso rasches Wiederzusammensetzen.This way is an easy and quick disassembly and Cleaning of the device, which consists of only a few parts, is possible and just as quick Reassemble.
Die Sägeblätter 23 und 24 sind an ihrer vorderen Stirnkante 39 mit Schneidezähren versehen. Die Wirkung der neuen Säge ist die, daß beim Antrieb der Exzenterwelle 31 durch eine vom Motor kommende biegsame Welle die Sägeblatthalter 25 und 26 und damit die Sägeblätter in Schwingbewegung versetzt werden, und zwar in entgegengesetzte Bewegung infolge der gegenseitigen Versetzung der Exzenter. Auf diese Weise wird eine vorzügliche Sägearbeit möglich, da sich bei den im Sinne der Abb. 2 (strichpunktierte Linien) entgegengesetzt bewegenden Sägeblättern die Schubkräfte aufheben.The saw blades 23 and 24 are at their front end edge 39 with Provide cutting spikes. The effect of the new saw is that when the eccentric shaft 31 is driven by a flexible shaft coming from the motor Saw blade holder 25 and 26 and thus the saw blades are set in oscillating motion in opposite motion as a result of the mutual displacement the eccentric. In this way, excellent sawing work is possible because in the case of those moving in opposite directions in the sense of Fig. 2 (dash-dotted lines) Saw blades cancel the thrust.
Die Schwingungsamplitude der Sägeblätter wird durch die Exzentrizität der Exzenter bestimmt und kann natürlich durch deren Änderung geändert werden.The oscillation amplitude of the saw blades is determined by the eccentricity the eccentric is determined and can of course be changed by changing it.
Die Wirkung dieser Säge ist gut und rasch, und bei der. verhältnismäßig großen Länge der Blätter ist es möglich, ohne weiteres Schnitte in großen Tiefen zu führen, was mit Kreissägen nicht möglich ist. Durch die Schlankheit des Gerätes kann man überall gut beikommen, so daß eine rasche Arbeit damit erreicht wird.The action of this saw is good and quick, and at the. relatively large length of the leaves it is possible to easily cut at great depths to do what is not possible with circular saws. Due to the slimness of the device you can get around anywhere easily, so that a quick work can be achieved with it.
