Abstract
Description
Die Erfindung betrifft ein chirurgisches Instrument sowie ein Verfahren zur Herstellung eines chirurgischen Instrumentes, das ganz oder in wesentlichen Teilen aus Aluminium oder einer Aluminiumlegierung besteht.The invention relates to a surgical instrument and a method for making a surgical Instrument made entirely or in substantial parts Aluminum or an aluminum alloy.
Chirurgische Instrumente, beispielsweise Pinzetten, Zangen, Scheren etc., werden üblicherweise aus einem körperverträglichen Metall hergestellt, beispielsweise aus Edelstahl oder aus Titan (DE 296 20 687 U1, DE 42 12 053 C1, US-PS 5 160 318). Diese Materialien haben sich gut bewährt, sie haben jedoch den Nachteil, daß sie relativ schwer sind und daß sie bei verschiede nen Untersuchungsverfahren die Untersuchungsergebnisse stören, beispielsweise bei der Kernspintomographie.Surgical instruments, such as forceps, Pliers, scissors, etc., are usually made of one manufactured metal compatible with the body, for example made of stainless steel or titanium (DE 296 20 687 U1, DE 42 12 053 C1, US-PS 5 160 318). These materials have proven themselves well, but they have the disadvantage that they are relatively heavy and that they are different the investigation results interfere, for example in magnetic resonance imaging.
Es ist auch bekannt, Geräte mit einem Ti-Al-N-Film zu versehen, und zwar durch sogenanntes Sputtering (Patents Abstracts of Japan, C-1162, 7. Februar 1994, Vol. 18/No.71).It is also known to use devices with a Ti-Al-N film too provided by so-called sputtering (Patents Abstracts of Japan, C-1162, February 7, 1994, Vol. 18 / No.71).
Es ist Aufgabe der Erfindung, ein chirurgisches Instru ment derart auszugestalten, daß einerseits eine dauer hafte und stabile Konstruktion beibehalten wird und andererseits das Gewicht der Instrumente herabgesetzt werden kann. It is the object of the invention to provide a surgical instru ment in such a way that on the one hand a duration strong and stable construction is maintained and on the other hand, the weight of the instruments is reduced can be.
Diese Aufgabe wird bei einem chirurgischen Instrument der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß es ganz oder in wesentlichen Teilen aus Aluminium oder einer Aluminiumlegierung besteht und daß die Oberfläche des Aluminiums bzw. der Aluminiumlegie rung mit einer dünnen Aluminiumnitridschicht versehen ist. This is the job of a surgical instrument of the type described above according to the invention resolved that it consists entirely or in substantial parts Aluminum or an aluminum alloy and that the surface of the aluminum or the aluminum alloy provided with a thin aluminum nitride layer is.
Es hat sich überraschenderweise herausgestellt, daß Aluminium oder Aluminiumlegierungen zur Herstellung von chirurgischen Instrumenten dann geeignet sind, wenn die aus Aluminium oder einer Aluminiumlegierung bestehenden Teilen mit einer Aluminiumnitridschicht umhüllt sind. Dadurch wird es möglich, die Oberfläche korrosionsbe ständig und kratzfest zu gestalten, so daß der an sich relativ wenig beständige Werkstoff Aluminium bzw. Alu miniumlegierung für den Einsatz von chirurgischen In strumenten geeignet wird, die in der Praxis einer außerordentlich hohen Beanspruchung ausgesetzt sind. Es wird dadurch nicht nur möglich, gewichtsmäßig wesent lich leichtere Instrumente herzustellen, es hat sich überraschenderweise auch herausgestellt, daß derartige Instrumente beispielsweise bei der Kernspintomographie praktisch keine künstlichen Signale (Artefakte) erzeu gen, außerdem ist dieses Material nicht magnetisch, so daß derartige chirurgische Instrumente besonders geeig net sind zum Einsatz während Operationen, die im offenen Kernspintomographen durchgeführt werden.It has surprisingly been found that Aluminum or aluminum alloys for the production of surgical instruments are suitable if the made of aluminum or an aluminum alloy Parts are coated with an aluminum nitride layer. This makes it possible to protect the surface from corrosion permanent and scratch-resistant, so that the in itself relatively less resistant material aluminum or aluminum Minium Alloy For Use Of Surgical In instruments that are used in practice are exposed to extremely high levels of stress. It is thereby not only possible, in terms of weight essential to manufacture lighter instruments, it has turned out to be Surprisingly, it was also found that such Instruments for magnetic resonance imaging, for example practically no artificial signals (artifacts) are generated gen, in addition, this material is not magnetic, like that that such surgical instruments are particularly suitable net are used during operations that are performed in open magnetic resonance imaging can be performed.
Die Aluminiumnitridschicht kann sehr dünn sein, sie kann beispielsweise zwischen 1 und 10 µm liegen.The aluminum nitride layer can be very thin to them can for example be between 1 and 10 µm.
Der Erfindung liegt auch die Aufgabe zugrunde, ein Ver fahren anzugeben, mit dem ein solches Instrument herge stellt werden kann.The invention is also based on the object of a Ver drive to indicate with which such an instrument was produced can be provided.
Diese Aufgabe wird beim Verfahren der eingangs be schriebenen Art erfindungsgemäß dadurch gelöst, daß die Oberfläche der aus Aluminium oder einer Aluminiumlegie rung bestehenden Teile mit einer dünnen Aluminium nitridschicht überzogen wird.This task is carried out in the process of the initially be written type solved according to the invention in that the Surface of the aluminum or an aluminum alloy tion existing parts with a thin aluminum nitride layer is coated.
Dabei kann insbesondere vorgesehen sein, daß das Auf bringen der Aluminiumnitridbeschichtung durch ober flächliches Aufschmelzen der aus Aluminium oder einer Aluminiumlegierung bestehenden Teile in einer Stick stoffatmosphäre erfolgt. Besonders günstig ist es, wenn das Aufschmelzen der Oberfläche der aus Aluminium oder einer Aluminiumlegierung bestehenden Teile durch Be strahlung der Oberfläche mit der Strahlung eines Lasers erfolgt, insbesondere der Strahlung eines Excimer lasers.It can be provided in particular that the on bring the aluminum nitride coating through the top flat melting of aluminum or a Aluminum alloy existing parts in a stick substance atmosphere takes place. It is particularly favorable if the melting of the surface of the aluminum or aluminum alloy parts by Be Radiation of the surface with the radiation of a laser occurs, in particular the radiation of an excimer lasers.
Die nachfolgende Beschreibung einer bevorzugten Ausfüh rungsform der Erfindung dient im Zusammenhang mit der Zeichnung der näheren Erläuterung. Es zeigen:The following description of a preferred embodiment Approximation form of the invention is used in connection with the Drawing for a more detailed explanation. Show it:
Fig. 1 eine schematische Ansicht eines chirur gischen Instrumentes mit wesentlichen Teilen aus Aluminium oder einer Alumi niumlegierung und Fig. 1 is a schematic view of a surgical instrument with essential parts made of aluminum or an aluminum alloy and
Fig. 2 eine Schnittansicht längs Linie 2-2 in Fig. 1. FIG. 2 is a sectional view taken along line 2-2 in FIG. 1.
Die Erfindung ist für beliebige chirurgische Instru mente geeignet, die aus Metall hergestellt sind oder die wesentliche metallische Teile aufweisen, nachfol gend wird die Erfindung am Beispiel eines Rohrschaft instrumentes 1 erläutert, welches einen rohrförmigen, metallischen Schaft 2 und im Innern desselben längsver schieblich gelagert eine Schub- und Zugstange 3 auf weist. Diese Schub- und Zugstange 3 kann durch zwei gegeneinander verschwenkbare Griffe 4, 5 gegenüber dem Schaft 2 in Längsrichtung verschoben werden und ver schwenkt dabei über einen geeigneten, in der Zeichnung nicht dargestellten Mechanismus zwei backenförmige Werkzeuge 6, 7 am Ende des Schaftes 2.The invention is suitable for any surgical instru ments that are made of metal or have the essential metallic parts, the following the invention will be explained using the example of a tubular shaft instrument 1 , which has a tubular, metallic shaft 2 and inside it slidably mounted a longitudinally Push and pull rod 3 has. This push and pull rod 3 can be displaced longitudinally with respect to the shaft 2 by two mutually pivotable handles 4 , 5 and pivots two jaw-shaped tools 6 , 7 at the end of the shaft 2 via a suitable mechanism not shown in the drawing.
Wesentliche Teile dieses Instrumentes sind aus Alumi nium oder einer Aluminiumlegierung hergestellt, dies trifft z. B. zu für den Schaft 2, für die Schub- und Zugstange 3 und für die Werkzeuge 6, 7.Essential parts of this instrument are made of Alumi nium or an aluminum alloy, this applies, for. B. for the shaft 2 , for the push and pull rod 3 and for the tools 6 , 7 .
Wenn die Teile aus einer Aluminiumlegierung bestehen, dann kann eine solche Legierung beispielsweise die folgende Zusammensetzung haben (nach DIN 1700):If the parts are made of aluminum alloy, then such an alloy can, for example, the have the following composition (according to DIN 1700):
Alle Oberflächen der in dieser Weise aus Aluminium oder einer Aluminiumlegierung bestehenden Teile sind mit einer dünnen Oberflächenschicht 8 aus Aluminiumnitrid versehen, die Dicke dieser Schicht kann zwischen 1 und 10 µm liegen.All surfaces of the parts made of aluminum or an aluminum alloy in this way are provided with a thin surface layer 8 of aluminum nitride, the thickness of this layer can be between 1 and 10 μm.
Zum Aufbringen dieser Schicht können die aus Aluminium oder einer Aluminiumlegierung bestehenden Teile bei spielsweise in einer Stickstoffatmosphäre unter Druck oberflächlich aufgeschmolzen werden, dies läßt sich durch Bestrahlung der Oberfläche mit einem Laser er reichen, beispielsweise mittels eines Excimerlasers. In einer solchen Stickstoffatmosphäre verbindet sich das aufgeschmolzene Metall an der Oberfläche des entspre chenden Teiles mit dem Stickstoff unter Bildung von Aluminiumnitrid, und diese Schicht hüllt die Teile oberflächlich vollständig ein, so daß ein Kontakt des metallischen Aluminiums mit der Umgebung ausgeschlossen wird. Die Aluminiumnitridschicht weist hervorragende Korrosionsbeständigkeit auf und ist mechanisch wider standsfähig, so daß in dieser Weise beschichtete Teile gegen Abnutzung und Beschädigung zuverlässig geschützt werden.To apply this layer, aluminum or an aluminum alloy for example in a nitrogen atmosphere under pressure be melted on the surface, this can be done by irradiating the surface with a laser he range, for example by means of an excimer laser. In such a nitrogen atmosphere combines the Melted metal on the surface of the corresponding corresponding part with the nitrogen to form Aluminum nitride, and this layer wraps the parts superficially completely, so that a contact of the metallic aluminum with the environment excluded will. The aluminum nitride layer has excellent Corrosion resistance and is mechanically reflected stable, so that parts coated in this way Reliably protected against wear and damage will.
