Description

Knochentrichter mit Stössel zur gezielten Sponoiosaplastik M.Richtei—Turtur Bone funnel with pestle for targeted sponoiosaplasty M.Richtei—Turtur

In den bisherigen Verfahren zur Übertragung von Knochentransplantaten wurde das Knochenniateria! offen in den Defekt eingelegt oder,z.B. bei WirbelkörpervErltrtzungen über einen geraden Trichter eingefüllt. Als sogenannte transpedikuläre Spongiosaplastik hat dieses Verfahren in der Behandlung van Wirbelsäulenverletzun^sn inissischan breiteIn previous procedures for transferring bone transplants, the bone graft was inserted openly into the defect or, for example, in the case of vertebral body injuries, it was filled in via a straight funnel. As so-called transpedicular cancellous bone grafting, this procedure has gained widespread acceptance in the treatment of spinal injuries.

Ein qewisser Nachteil dieser Methode besteht noch darin,daß nur ciBr Wirbelkörper selbst mit Knochenmehl aufgefüllt werden kann, nicht jedoch der benachbarte Bandscheibenraum,sei es cranial oder csidi:,da der starre ,gerade Trichter keine ausreichende Reichwe:; ss aufweist.A certain disadvantage of this method is that only the vertebral body itself can be filled with bone meal, but not the adjacent disc space, be it cranial or sidial, since the rigid, straight funnel does not have sufficient reach.

p.'ifgabe eier verwiegenden Es^finduntj ist es, die gezielte Pl-:*::ierung von Bpongiosa (>■ ,-iOchenmE-h '·) in Hohlräumen tu srmög!ichen.Insbesondere kann durch dieses einfache Instrumentarium auch eine gezielte Auffüllung des Zwischenwirbelraumes mit Sponsion ·.-. vorgenommen werden. Darüberhinaus kann der- vorgestellte Trichter auch als Instrumentarium dienen um Bandscheibenmaterial aus dem Zwischenwii belraum zu entfernen.The aim of this instrument is to enable the targeted placement of pongiosa (>■ ,-iOchenmE-h '·) in hollow spaces. In particular, this simple instrument can also be used to specifically fill the intervertebral space with spondylosis. In addition, the funnel presented can also be used as an instrument to remove disc material from the intervertebral space.

Gelöst werden dipse Aufgaben durch ein einfaches Instrumentarium,wie es in Anspruch 1 gekennzeichnet und in Fig.l abgebildet ist.These tasks are solved by a simple instrumentation as characterized in claim 1 and shown in Fig. 1.

Es handelt sich um ein etwa 8 mm dickes Arbeitsrohr(1),das eine Krümmumg mit einem Kreisradius von etwa 2,5 cm auf weist (Fig. 1) .Die Wandstärke des Rohres liegt bei Imm,sodaf3 das Innenlumen eine Weite von 6 mm hat.Gemäß dem unterschiedlichen Anwendungsbedarf können diese Maatfe auch variieren(Fig.2).Das Rohr kann sowohl dicker als auch schlanker sein und der Krümmungsradius kann stärker oder Schwächer ausgeprägt sein.In jedem Falle ist das eine Ende des Rohres trichterförmig bis auf einen Durchmesser von ca.2,5 cm geweitet(2).Das andere Ende ist rechtwinklig nach einer Länge von etwa 7-10 cm abgeschnitten.It is a working tube (1) approximately 8 mm thick, which has a curvature with a radius of about 2.5 cm (Fig. 1). The wall thickness of the tube is 1 mm, so that the inner lumen has a width of 6 mm. These dimensions can also vary according to the different application requirements (Fig. 2). The tube can be either thicker or thinner and the radius of curvature can be more or less pronounced. In any case, one end of the tube is widened in a funnel shape to a diameter of about 2.5 cm (2). The other end is cut off at a right angle to a length of about 7-10 cm .

Zu diesen gebogenen Trichtern gphören Stössel mit Handgriffen,die sich mit ihrem Aussendurchmesser dem Innendurchmesser des gebogenen Arbeitstrichters anpassen und die gleiche Krümmung wie der dazugehörige Trichter aufweisen(3).Sie können also durch den gebogenen Trichter hindurchgeschoben werden.Zur besseren praktischen Handhabung können diese Stössel vor dem der Trichterrundung angepassten gebogenen Ende noch mit einer Gegenbiegung versehen sein (Fig.l u.2).These curved funnels include pestles with handles whose outer diameter matches the inner diameter of the curved working funnel and has the same curvature as the corresponding funnel (3). They can therefore be pushed through the curved funnel. For better practical handling, these pestles can be provided with a counter-bend in front of the curved end that matches the rounded shape of the funnel (Fig. 1 and 2).

Neben den in Fig.l und 2 abgebildeten Stöpseln wird das Instrumentarium durch weitere biegungskongruente Werkzeuge ergänzt(nicht abgebildet).So z.B. einen kongruenten Baugeransatz,der zum gezielten Absaugisn von Knochen-, Bandscheibenfragmenten und Blut benutzt wird, eine kongruent gebogene Gewebezange (Rongeur),mit der ebenfalls Material aus dem Wirbelkörper oder dem Bandscheibenraum entfernt werden kann. Dieser Rongeur muß dabei kombiniert sein mit einer Saugvorrichtung.In addition to the plugs shown in Fig. 1 and 2, the instrumentation is supplemented by other tools with the same bend (not shown). For example, a congruent construction tool, which is used for the targeted suction of bone and disc fragments and blood, and a congruently curved tissue forceps (rongeur), which can also be used to remove material from the vertebral body or the disc space. This rongeur must be combined with a suction device.
