Abstract
Description
Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruch 1. In der heutigen Radiologie wird der Kernspintomograph gerade deswegen gern eingesetzt, da er die Weichteile des Körpers besser aufzeichnet als das Röntgen- oder das Ultraschallverfahren, ohne ionisierende Strahlung auskommt und speziell das einzige brauchbare Verfahren ist, mit dem man in das Knocheninnere einsehen kann. Gerade hier werden Untersuchungen von Knochentumore vorgenommen. Zu solchen Untersuchungen benötigt man Biopsiegeräte zur Entnahme von Knochenbiopsien.The invention relates to a device according to the preamble of claim 1. In today's The MRI scanner is often used for radiology because it is the soft tissue of the Body better than X-ray or ultrasound, without ionizing Radiation gets by and especially is the only usable method with which one can get into the Can see inside the bone. This is where examinations of bone tumors are carried out performed. Such examinations require biopsy devices for the extraction of Bone biopsies.
Um in den Knochen zu gelangen und eine Biopsie zu entnehmen, muß der Knochen angebohrt werden. Dies kann manuell oder auch mittels Bohrmaschine geschehen. Jedoch sind herkömmliche Bohrmaschinen nicht kernspintauglich, sie werden a) im Magnetfeld abgelenkt oder setzen b) erhebliche behindernde Bildartefakte. Dieses Problem zu lösen ist Aufgabe der Erfindung.To get into the bone and take a biopsy, the bone must be drilled become. This can be done manually or using a drill. However, are conventional Drills not suitable for nuclear spin, they are a) deflected in the magnetic field or set b) significant image artifacts obstructing. To solve this problem is the object of the invention.
Die Lösung des Problems wird in den folgenden Figuren näher erläutert:The solution to the problem is explained in more detail in the following figures:
Fig. 1 Arbeitsrohr mit Einstechdorn, Fig. 1 working tube with spike,
Fig. 2 Arbeitsrohr mit Bohrerantrieb elektrisch und manuell, Fig. 2 working tube with a drill drive electric motor and manual,
Fig. 3 Bohrer mit Auswerfer, Fig. 3 drills with ejector,
Fig. 4 Bohrmaschine im Überblick, Fig. 4 drill at a glance,
Fig. 5 Bohrmaschine in Durchsicht, Fig. 5 drill in phantom,
Fig. 6 Bohrmaschine im Überblick, andere Bauform. Fig. 6 drill at a glance, different design.
Die Knochenbiopsie erfolgt wie folgt:
Zunächst wird der Einstechdorn 1 in das Arbeitsrohr 2 eingeführt und beide werden durch Einstechen in
den Körper bis auf den Knochen geschoben, dann wird der Dorn 1 herausgezogen und mit Hilfe des
Griffstuckes des Dorns 1, der als Gewicht ausgeformt ist, wird das Arbeitsrohr 2 an den Knochen
geschlagen, um dieses am Knochen zu fixieren. Danach wird der Knochenbohrer 3 in das Arbeitsrohr 2
eingeführt und der Knochen angebohrt. All dies erfolgt unter Kernspintomographiesicht. Der
Knochenbohrer 3a wird entweder mittels eines elektrischen Bohrantriebes in den Knochen gebohrt
oder der Knochenbohrer 3b wird mit einem Handgriff 4 in den Knochen gebohrt. Der Bohrer 3 wird
dann durch die Lesion gebohrt, herausgezogen und mit Hilfe des Auswerfers 5 die Probe aus dem
Knochenbohrer 3 (3a oder 3b) entnommen.
The bone biopsy is done as follows:
First, the insertion pin 1 is inserted into the working tube 2 and both are pushed by piercing the body to the bone, the mandrel 1 is pulled out and with the aid of the handle Stuckes of the mandrel 1, which is formed as a weight, the working tube 2 is to beaten the bone to fix it to the bone. Then the bone drill 3 is inserted into the working tube 2 and the bone is drilled. All this is done under magnetic resonance imaging. The bone drill 3 a is either drilled into the bone by means of an electric drill drive or the bone drill 3 b is drilled into the bone with a handle 4 . The drill 3 is then drilled through the lesion, and pulled with the aid of the ejector 5, the sample from the bone drill 3 (3 a or 3 b) taken.
In Fig. 4 und 6 sind verschiedene Ansichten des motorgetriebenen kernspintauglichen Knochenbiopsiebohrers gezeigt. Die Bohrmaschine 6 ist als Handgriff ausgestattet, die mittels eines Bohrfutters 7 den elektromechanischen Antrieb 3a trägt. Fig. 5 zeigt den inneren Aufbau. Der Motor 8 ist als piezoelektrischer bzw. Ultraschallmotor aufgebaut. Er sitzt im Inneren des Handstückes 6 und ist mit einem abgeschirmtem Kabel gegen HF-Einstreuung an die Motorsteuerung gekoppelt. Der Motor 8 kann z. B. so aufgebaut sein, wie in der Patentanmeldung DE 197 09 267.5. In Figs. 4 and 6 show various views of the motor driven MRI compatible biopsy bone drill bit are shown. The drilling machine 6 is equipped as a handle which carries the electromechanical drive 3 a by means of a drill chuck 7 . Fig. 5 shows the internal structure. The motor 8 is constructed as a piezoelectric or ultrasonic motor. It sits inside the handpiece 6 and is coupled to the motor control with a shielded cable against RF interference. The motor 8 can e.g. B. be constructed as in the patent application DE 197 09 267.5.
