Abstract
Description
Die Erfindung betrifft ein Instrumentarium zur retrograden Dekompression des zervikalen engen Spinalkanals und dient der Entlastung des Rückenmarks bei der spondylogenen Hals markschädigung. Die Erfindung kann in der Neurochirurgie und in der Orthopädie eingesetzt werden.The invention relates to instruments for retrograde Decompression of the cervical narrow spinal canal and serves the relief of the spinal cord at the spondylogenic neck marrow damage. The invention can be used in neurosurgery and used in orthopedics.
Die Operation der spondylogenen Halsmarkschädigung erfolgt bisher über das Ausbohren des Bandscheibenraums nach dem Verfahren von Cloward (Cloward, R. B.: Lesions of the intervertebral discs and their treatment by interbody fusion methods. In: Clin. Orthop. Philadelphia 27 1963 S. 51). Die dorsalen, den Spinalkanal einengenden Randzacken werden mit einem abgewinkelten Löffel stückweise abge tragen. Mit dem Löffel kann man jedoch nur einen kleinen Teil der Osteophyten erreichen. Beim Arbeiten mit dem Mi kroskop kann man aufgrund der besseren Sichtverhältnisse zwar einen kleinen Teil einsehen, der Hauptteil entzieht sich jedoch dem Einblick, da er sich an der Rückseite des Wirbelkörpers erstreckt. Das Abrutschen des abgewinkelten Löffels in Richtung des Rückenmarks wird durch die Erfah rung des Operateurs vermieden. Da die Randwülste nur unvollständig entfernt werden können, muß zur Entlastung des Rückenmarks ein zweiter Eingriff von drosal ausgeführt werden, um das Rückenmark aus der Umklammerung zu befreien.The operation of the spondylogenic cervical cord damage takes place hitherto about drilling out the intervertebral disc space after Cloward's method (Cloward, R.B .: Lesions of the intervertebral discs and their treatment by interbody fusion methods. In: Clin. Orthop. Philadelphia 27 1963 P. 51). The dorsal marginal tines constricting the spinal canal be scraped piece by piece with an angled spoon wear. With the spoon you can only make a small one Reach part of the osteophytes. When working with the Mi You can see the microscope because of the better visibility see a small part, the main part deprives However, look at the insight as it is located at the back of the Spine extends. The slipping of the angled Spoon towards the spinal cord is experienced avoidance of the surgeon. Because the ridges only can be removed incompletely, must be relieved of the spinal cord a second drosal operation is performed to free the spinal cord from the clasp.
Das Problem besteht darin, ein perkutanes System zu ent wickeln, welches einerseits die Entfernung der dorsalen Randzacken ermöglicht, andererseits die ventrale Brückenbildung des geschädigten Segmentes induziert und durch eine Spongiosaeinschwämmung beschleunigt.The problem is to remove a percutaneous system wrap, which is the removal of the dorsal Edge jags allow, on the other hand the ventral Bridge formation of the damaged segment is induced and accelerated by a spongiosa sponge.
Das erfindungsgemäße Instrumentarium besteht aus einer perkutan einzubringenden kombinierten Führungs- und Abstützhülse und dem eigentlichen Osteophytenfrässystem, welches in einer Spül- und Absaugeinrichtung integriert ist.The instrumentation according to the invention consists of a Combined guide and to be inserted percutaneously Support sleeve and the actual osteophyte milling system, which is integrated in a flushing and suction device is.
Die Führungs- und Abstützhülse besteht aus einem Doppel rohr. Am Ende des inneren Rohres befinden sich drei drei eckförmige Segmente, die gelenkig angeordnet sind. Das Gelenk ermöglicht eine Auskippbewegung bis 90° zur Rohr achse. Durch das darüberliegende Rohr werden die Segmente gestreckt gehalten, so daß eine lanzettförmige Spitze ent steht. Beim Zurückziehen des Außenrohres und leichtem Druck kippen die Segmente 90° zur Rohrachse ab und bilden so ein Abstützsystem an der Vorderkante der Wirbelkörper.The guide and support sleeve consists of a double pipe. At the end of the inner tube there are three three corner-shaped segments that are articulated. The The joint allows a tilting movement up to 90 ° to the pipe axis. The segments are through the tube above kept stretched so that a lancet-shaped tip ent stands. When pulling back the outer tube and applying slight pressure tilt the segments 90 ° to the pipe axis and thus form Support system on the front edge of the vertebrae.
Das Osteophytenfrässystem besteht aus zwei Federstahlla mellen, die nach außen gekrümmt vorgespannt sind. Die Lamellen sind in einer Antriebswelle fest verankert und werden in einem Stellrohr geführt. Durch Vordrehen des Rohres können die Lamellen vollständig versenkt werden. Dreht man das Rohr zurück, werden die Lamellen freigege ben. Der Fräskopf arbeitet in zwei Positionen (Fig. 1). Die erste Position entsteht durch Zurückdrehen des Rohres um 2 mm. Dabei kann sich die Krümmung der Lamellen noch nicht voll entfalten, so daß zwei seitlich vorn stehende Schneid flächen entstehen. Beim weiteren Freigeben der Lamellen können sie sich im Winkel von 90° zur Achse der Antriebs welle einstellen. Die Innenfläche der Segmente ist mit Diamantsplittern besetzt, so daß eine retrograde Schneid wirkung an der Wirbelrückfläche entsteht. Durch leichtes Zurückziehen des Osteophytenfrässystems kommt die Innen fläche der Segmente mit den Osteophyten in Kontakt. Die Antriebswelle ist mit dem Motor verbunden und führt eine oszillierende Bewegung aus. Eine Justiereinrichtung zwi schen Antriebswelle und Stellrohr ermöglicht eine 1/10 mm genaue Einstellung des Hubes der Lamellen. Die Länge der Lamellen und ihr Hub werden nach der im Bildwandler erkenn baren Größe der Osterophyten eingestellt. Das Stellrohr besitzt einen Schlauchanschluß zur Spülung. Unterhalb des Stellrohres befindet sich das Absaugrohr, um die Spül flüssigkeit wieder zu entfernen. Das Gesamtsystem kann durch die Führungs- und Abstützhülse geleitet und so in den Bandscheibenraum geführt werden. Um jedes Abrutschen der Fräse in Richtung Spinalkanal zu verhindern, wird sie wäh rend des Fräsvorganges über eine Gleitverbindung mit der Abstützhülse verbunden, so daß nur eine Bewegung nach ven tral möglich wird.The osteophyte milling system consists of two spring steel lamellae, which are biased outwards. The slats are firmly anchored in a drive shaft and are guided in an adjusting tube. The slats can be completely recessed by turning the tube. If you turn the tube back, the fins are released. The milling head works in two positions ( Fig. 1). The first position is created by turning the tube back 2 mm. The curvature of the lamellae cannot yet fully unfold, so that two cutting surfaces standing to the side arise. When the slats are released further, they can adjust themselves at an angle of 90 ° to the axis of the drive shaft. The inner surface of the segments is covered with diamond chips, so that a retrograde cutting effect is created on the back surface of the vertebrae. The inner surface of the segments comes into contact with the osteophytes by slightly withdrawing the osteophyte milling system. The drive shaft is connected to the motor and performs an oscillating movement. An adjustment device between the drive shaft and the control tube enables a 1/10 mm precise adjustment of the stroke of the slats. The length of the slats and their stroke are set according to the size of the osterophytes that can be seen in the image converter. The control tube has a hose connection for flushing. The suction tube is located below the control tube to remove the flushing liquid. The entire system can be guided through the guide and support sleeve and thus guided into the intervertebral disc space. In order to prevent any slipping of the cutter in the direction of the spinal canal, it is connected during the milling process via a sliding connection with the support sleeve, so that only a movement toward the center is possible.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Fig. 2 zeigt die Arbeitsweise des Frässystems.An embodiment of the invention is shown in the drawing and will be described in more detail below. Fig. 2 shows the operation of the milling system.
Das erfindungsgemäße Instrumentarium soll nachstehend in Funktion bei einer perkutanen retrograden Dekompression des Spinalkanals näher erläutert werden:The instruments according to the invention are described below in Function in a percutaneous retrograde decompression of the Spinal canal are explained in more detail:
Am Vorderrand des Musculus sternocleidomastoideus wird ein 2 cm langer Hautschnitt gelegt und das Platysma indiziert. Unter Bildwandlerkontrolle wird mit der Führungsabstützhül se eingegangen und diese bis zur Vorderfläche der Halswir belsäule vorgeschoben. Auf dem geschädigten Segment wird die Führungshülse zu einer Abstützhülse umgewandelt, so daß die Abstützflächen auf dem Wirbelkörper liegen und das Lumen des Rohres freigegeben wird. Das Frässystem kann über diese Hülse vorgeschoben und so durch das vordere Längsband gebracht werden. 2 mm unterhalb des vorderen Längsbandes wird der Fräskopf über die Justiereinrichtung in die Posi tion 1 (siehe Fig. 1) gebracht. Mit dieser Fräseinstellung wird der vordere Teil des Anulus fibrosus reseziert. Der Fräskopf wird dann wieder eingezogen und kurz gespült. Jetzt wird das Frässystem durch den Bandscheibenraum ge führt und in Höhe der Rückfläche des Wirbelkörpers entfal tet. In der Position 2 des Fräskopfes (siehe Fig. 1) ist jetzt ein retrogrades Arbeiten möglich. Nach Führung der Segmente an die Osteophyten wird das Frässystem in der Abstützhülse eingeklinkt und so in Arbeitsposition ge bracht. Unter ständiger Bildwandlerkontrolle erfolgt das Abfräsen der Osteophyten (Fig. 2). Dabei erfolgt sowohl eine Spülung, als auch eine Absaugung der Spülflüssigkeit. Durch eine Verstellung des Absaugrohres kann ein Teil des abgesaugten Knochenmaterials unter das vordere Längsband, d.h. in den vorderen Abschnitt des Bandscheibenraums einge bracht werden. Nach dem Abfräsen der Osteophyten wird der Fräskopf eingefahren und das System entfernt.A 2 cm skin incision is made on the front edge of the sternocleidomastoid muscle and the platysma is indicated. Under image converter control, the guide support sleeve is received and advanced to the front surface of the cervical spine. On the damaged segment, the guide sleeve is converted into a support sleeve so that the support surfaces lie on the vertebral body and the lumen of the tube is released. The milling system can be advanced over this sleeve and brought through the front longitudinal belt. 2 mm below the front longitudinal belt, the milling head is brought into position 1 via the adjusting device (see FIG. 1). With this milling setting, the anterior part of the annulus fibrosus is resected. The milling head is then retracted and rinsed briefly. Now the milling system is guided through the intervertebral disc space and unfolded at the level of the back surface of the vertebral body. Retrograde working is now possible in position 2 of the milling head (see Fig. 1). After guiding the segments to the osteophytes, the milling system is latched into the support sleeve and thus brought into the working position. The osteophytes are milled off under constant image converter control ( FIG. 2). Both rinsing and suction of the rinsing liquid take place. By adjusting the suction tube, part of the extracted bone material can be placed under the front longitudinal ligament, ie in the front section of the intervertebral disc space. After milling the osteophytes, the milling head is retracted and the system removed.
