Abstract
Description
Die Erfindung betrifft ein Klingenblatt für Scheren, die insbesondere zum Einsatz in der minimalinvasiven Chirurgie vorgesehen sind. Derartige Klingenblätter weisen in der Regel zum einen ein Lagerteil auf, in dem beispielsweise eine Bohrung für einen Schwenklagerzapfen sowie eine Bohrung für die Anlenkung eines Zug- oder Schubdrahtes zur Scherenbetätigung vorgesehen sind. Zum anderen hat das Klingenblatt ein Klingenteil mit einer Schneide.The The invention relates to a blade for scissors, in particular are intended for use in minimally invasive surgery. Such blades have usually on the one hand a bearing part, in which, for example a hole for a pivot bearing pin and a hole for the articulation of a train or shear wire for scissors operation are provided. On the other hand, the blade has a blade part with a cutting edge.
In der minimalinvasiven Chirurgie werden Scheren mit geraden Klingenblättern oder auch sogenannte Metzenbaumscheren mit gekrümmten Klingenblättern eingesetzt. Derartige Scheren dienen nicht nur zum Trennen von Gewebe, sondern auch zur schnellen Verödung von verletzten Gefäßen während der Operation. Beim Veröden werden die Scherenklingen mit Hilfe einer angelegten elektrischen Spannung erhitzt und an die verletzte Stelle gehalten. Durch die rasche Koagulation des austretenden Blutes wird ein weiterer Blutfluss unterbunden, was verhindert, dass in den Operationsbereich einströmendes Blut die Sicht über das Endoskop trübt. Der Chirurg wird somit in die Lage versetzt, ohne Herausziehen der Instrumente die Operation fortzusetzen.In The minimally invasive surgery will scissors with straight blades or also used so-called Metzenbaumscheren with curved blade blades. Such scissors not only serve to separate tissue, but also for fast desolation of injured vessels during the Surgery. When scorching The scissor blades are made using an applied electrical voltage heated and held in the injured area. Due to the rapid coagulation the escaping blood prevents another blood flow, what prevents blood entering the surgery area the view over the endoscope is clouding. The surgeon is thus enabled, without pulling out of Instruments to continue the operation.
Problematisch bei den bekannten minimalinvasiv-chirurgischen Scheren ist deren starker Verschleiß insbesondere bei häufiger Nutzung der Koagulationsfunktion. Die dabei stattfindende Erhitzung der Klingenblätter führt nämlich zu einer Erweichung des Stahlwerkstoffes mit entsprechend schnellem Stumpf-Werden. Ferner können sich auch oftmals Lichtbögen zwischen den Schneiden (bipolarer) Scheren ausbilden, die zu einem mikro-abrasiven Effekt mit entsprechenden Mikro-Ausbrüchungen im Schneidenbereich führen können. Als Folge ist eine stark nachlassende Schneidwirkung der Scheren zu verzeichnen, was zu einer erheblich erschwerten Operation mit einem eher als „Rupfen" zu bezeichnenden Schneidvorgang führt.Problematic in the known minimally invasive surgical scissors is their heavy wear in particular at more frequent Use of the coagulation function. The thereby taking place heating the sound leaves leads to a softening of the steel material with a correspondingly rapid dulling. Furthermore, can often also arcs form between the cutting edges (bipolar) scissors, which become a micro-abrasive Effect with corresponding micro-Ausbrüchungen in the cutting area to lead can. As a consequence, a severely decreasing cutting action of the scissors to register, resulting in a much more difficult operation with a rather than "plucking" to call Cutting process leads.
Ausgehend von der geschilderten Problematik liegt der Erfindung die Aufgabe zugrunde, ein Klingenblatt für Scheren insbesondere zum Einsatz in der minimalinvasiven Chirurgie zu schaffen, das trotz einer Beheizbarkeit eine erheblich längere Standzeit aufweist.outgoing From the described problem of the invention is the task underlying, a blade blade for Scissors especially for use in minimally invasive surgery to create, despite a Heizbarkeit a significantly longer life has.
Diese Aufgabe wird laut Kennzeichnungsteil des Anspruches 1 durch einen Schneideinsatz aus Keramikwerkstoff gelöst, der in einer Ausnehmung im Schneidbereich des Klingenteils eingesetzt und an dem die Schneide selbst ausgebildet ist.These Task is according to the characterizing part of claim 1 by a Cutting insert made of ceramic material dissolved in a recess used in the cutting area of the blade part and on which the cutting edge self-trained.
Der
Keramikwerkstoff des Schneideinsatzes zeichnet sich durch eine große Härte und
Temperaturbeständigkeit
aus, sodass das Material aufgrund seiner Abrasions- und Erweichungsfestigkeit
ideal für den
Schneidbereich des Klingenblattes ist. Das Standvermögen des
Klingenblattes wird in diesem Zusammenhang insbesondere dadurch
gefördert, dass
der Schneideinsatz aus Keramikwerkstoff als gesondertes Teil beispielsweise
durch Sintern vorgefertigt und dieses Halbzeug dann in der Ausnehmung am
Klingenteil dauerhaft fixiert wird. Dies ist ein entscheidender
Vorteil gegenüber
beispielsweise den im US-Patent

Es zeigen:preferred embodiments of the invention are specified in the subclaims whose characteristics, Details and advantages of the following description of an embodiment clearly become. Show it:

Als weitere Materialien für den Schneideinsatz können beispielhaft auch Siliziumnitrid oder Keramik-Composites der Materialpaarungen Oxidkeramik/Oxidkeramik (z.B. Yttriumoxid/Aluminiumoxid) bzw. Oxidkeramik/Nicht-Oxidkeramik (z.B. aus Oxidkeramikmaterialien wie Yttriumoxid und Aluminiumoxid sowie Nicht-Oxidkeramikmaterialien wie Siliziumnitrid und Molybdändisilizid) genannt werden.When other materials for the cutting insert can for example, silicon nitride or ceramic composites of the material pairings Oxide ceramics / oxide ceramics (e.g., yttria / alumina) or oxide ceramics / non-oxide ceramics (For example, oxide ceramics such as yttria and alumina and non-oxide ceramics such as silicon nitride and molybdenum disilicide) to be named.
