Abstract

The bone cutting auxiliary device provides a true separating line and prevents the cutting blade running away from the required cutting direction. The device consists of a housing containing the cutting mechanism and has a support arm (17) coupled to it. Pref. the housing and the support arm (17) are pivoted together on a common axis and the angle between the housing and the arm (17) can be read off a scale and fixed by a set screw. A cutting blade can be fitted in a slit in a guide arm (15) in the housing or alternatively a laser device or other cutting device can be used.

Description

Trennvorrichtung für medizinische Zwecke Die Erfindung betrifft eine Trennvorrichtung für medizinische Zwecke. Die Erfindung ermöglicht bzw. erleichtert insbesondere die Trennung von Knochen in vorgegebener bzw. berechneter i3bene, Die zurzeit gebräuchlichen Trennvorrichtungen geben eine exakte Einhaltung der vorgesehenen Trennebene nicht vor. Diese wird vom Operateur gefühlsmäßig von Hand bewerkstelligt. Die Sägeblätter der Trennvorrichtungen neigen erfahrungsgemäß zum "Weglaufen" aus der gewünschten Trennrichtung. Separating device for medical purposes The invention relates to a Separator for medical purposes. The invention enables or facilitates in particular the separation of bones in a given or calculated plane, the Separating devices currently in use ensure that the intended ones are adhered to exactly Parting line not before. This is done emotionally by hand by the surgeon. Experience has shown that the saw blades of the cutting devices tend to "run away" the desired direction of separation.

Der Erfindung liegt die Aufgabe zugrunde, ein Trennsystem vorzugsweise für Knochen zu ermöglichen, das die Einhaltung einer vorgegebenen Trennebene gewährleistet und zudem ein "Weglaufen" des Sägeblattes aus der gewünschten Trennrichtung verhindert.The invention is based on the object, preferably a separation system to allow for bones, which ensures compliance with a predetermined parting plane and also prevents the saw blade from "running away" from the desired cutting direction.

Diese Aufgabe wird erfindugsgemäß dadurch gelöst, daß das Gehäuse (1) mit dem Trennmechanismus durch einen verstellbaren Auflegearm (17) während des Trennvorgangs winkelstabil lagefixiert wird, der Auflegearm (17) (im Querschnitt vorzugsweise kreisbogen förmig ausgebildet ist und - falls verwerdet - das Sägeblatt in Führungsschlitzen der Führungsarme (15) richtungsstabil geführt wird.This object is achieved according to the invention in that the housing (1) with the separation mechanism through an adjustable support arm (17) during the Cutting process is fixed in position at a stable angle, the support arm (17) (in cross section is preferably formed in the shape of a circular arc and - if grounded - the saw blade is guided in a directionally stable manner in guide slots in the guide arms (15).

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß durch die stabile Auflage des Auflegearms(17) auf dem zu trennenden Knochen o.ä. und dem mittels einer Einstellvorrichtung (16j fixierten Winkel zwischen dem Gehäuse(1) und dem Auflegearm(17) die Trennrichtung - also auch die Trennebene - exakt eingehalten wird. Werner wird dieser Vorteil flankiert durch Führungsschlitze in den Führungsarmen(15), in denen das Sägeblatt(4) richtungsstabil geführt wird, falls Sägeblätter verwendet werden.The advantages achieved with the invention are in particular: that by the stable support of the support arm (17) on the bone to be separated or the like and the angle between the Housing (1) and the support arm (17) the direction of separation - including the parting plane - is exactly adhered to. Werner, this advantage is flanked by guide slots in the guide arms (15), in which the saw blade (4) is guided in a directionally stable manner, if saw blades are used.

Ä Das Ausführungsbeispiel in Fig.6 zeigt das Gehäuse(1) mit einem um die Einstellvorrichtung(1 6) schwenkbaren Auflegearm(17), Mittels einer Rändelschraube kann der an einer Skaleneinteilung ablesbare Winkel zwischen Gehäuse(1) und Auflegearm(17) eingestellt und fixiert werden. Ä The embodiment in Figure 6 shows the housing (1) with a support arm (17) pivotable around the adjustment device (1 6) by means of a knurled screw the angle between the housing (1) and the support arm (17), which can be read off on a scale adjusted and fixed.

Die Püiirungsarme(15) sind im Ausführungsbeispiel mit dem Gehäuse fest verbunden gezeichnet, was aber keineswegs für die Führungsfunktion zwingend ist. Die Führungsarme(15) können auch nach Einlegen in die Operationsstelle mit dem Gehäuse formschlüssig verbunden werden. Die Führungsarme(15) sind mit Eührungsschlitzen versehen, in denen das Trennmesser(4) geführt wird.The Püiirungsarme (15) are in the embodiment with the housing drawn firmly connected, but this is by no means mandatory for the management function is. The guide arms (15) can also be used after being placed in the surgical site be positively connected to the housing. The guide arms (15) have guide slots provided, in which the cutting knife (4) is guided.

Das Gehäuse(1) kann auch als Aufnahmeteil für eine Laserkanone oder andere geeignete Trennmittel dienen.The housing (1) can also be used as a receiving part for a laser gun or other suitable release agents are used.

Das Ausfihrungsbeispiel in Fig. zeigt eine Trennvorrichtung, die mit vorhandenen Trennsystemen verbunden werden kann. Eine Führungsschiene(19) wird mit dem Gehäuse eines vorhandenen Trennsystems (20) formschlüssig verbunden und im Führungsarm(18), der über die Einstellvorrichtung(16) mit dem Auflegearm(17) verbunden ist, geführt.The Ausfihrungsbeispiel in Fig. Shows a separating device with existing separation systems can be connected. A guide rail (19) is with positively connected to the housing of an existing separation system (20) and in the guide arm (18), which is connected to the support arm (17) via the adjustment device (16).

In Fig. 3 sind Ausführungsbeispiele des Auflegearms aufgezeigt.In Fig. 3 embodiments of the support arm are shown.
