Abstract

The bone sawing blade has a fine cut. The smooth bone is removed by a free grinding technology. The blade comprises a fine cross-section with a radius and a teeth arrangement within the radius. A diagonally fine cross-section of the teeth and a file cross-section and/or grating on the lower side and the upper side of the saw blade is provided.

Description

Knochensägeblätter üblicher Bauteile haben den Nachteil während des Prozesses der Betätigung nur für eine unzureichende Abfuhr der abfallenden bzw. der sich lösenden Knochenspäne zu sorgen. Grund hierfür ist der fehlende Freischliff am Sägeblatt.Bone saw blades more usual Components have the disadvantage during the process of operation only for one insufficient removal of the sloping or dissolving bone chips to ensure. reason therefor is the missing clearance on the saw blade.

Mit dem in diesem Gebrauchsmuster angemeldetem Produkt, einem medizintechnischen Knochensägeblatt wird das Problem grundlegend gelöst und durch die zusätzlichen Freischliffe am Knochensägeblatt für eine optimale Abfuhr der Knochenspäne gesorgt.With the product registered in this utility model, a medical device bone saw blade the problem is solved fundamentally and through the additional Free edges on the bone saw blade for one optimal removal of bone chips taken care of.

Durch die im Radius geschliffenen Sägezähne am Knochensägeblatt wird eine optimale Ausnutzung aller Sägezähne gewährleistet. Um den Knochen bei der Herstellung von Querschnitten nicht zu zerreißen, sondern sauber zu durchtrennen, wird der so genannte Schrägschliff angewendet. Die Zahnspitzen des Knochensägeblattes wirken hierbei wie Vorschneider. Durch den Radius der verzahnten Zähne wird zusätzlich die Schnittkraft verringert und für ein leichtes schneiden gesorgt.By the radiused saw teeth on the bone saw blade ensures optimum utilization of all saw teeth. To the bone not to tear the production of cross sections, but to cut clean, is called the oblique cut applied. The tooth tips of the bone saw blade act like pre-cutters. Due to the radius of the toothed teeth is additionally the Cutting power reduced and for one easy cutting worried.

Für optimale Kühlung der Zähne dienen die eingeschliffenen Kühlnuten, die zusätzlich nicht nur eine geringe Wärmeentwicklung des Sägeblattes, kürzere Sägezeit sowie eine höhere Standzeit garantiert, sondern auch eine bessere Abfuhr der Knochenspäne welche die Sicht auf das Operationsfeldes verbessert.For optimal cooling the teeth serve the ground cooling grooves, the additional not only a low heat development of the saw blade, shorter sawing time as well a higher one Lifetime guaranteed, but also a better removal of bone chips which improved the view of the surgical field.

Durch den Feilenschliff bzw. Raspelung auf der Unter- und Oberseite des Sägeblattes, dass einen zusätzlichen Vorteil hat, wird beim Sägen gleichzeitig eine Glättung des Knochens bewirkt.By the file sharpening or rasping on the lower and upper side of the saw blade, that an extra Advantage is when sawing at the same time a smoothing of the bone causes.

Um eine beiderseitige gleichmäßige Wirkung zu erziehlen, werden die Zähne abwechselnd nach der rechten und nach der linken Seite zu schräg geschliffen. Durch diese spezielle Schneidegeometrie erhält man eine hervorragende Schneideeigenschaft, welche einen sauberen Schnitt und das Risiko einer thermischen Nekrose minimiert.Around a mutual uniform effect too erziehlen become the teeth alternately ground to the right and to the left to oblique. This special cutting geometry provides an excellent cutting property, which a clean cut and the risk of thermal necrosis minimized.

Schutzansprüche beziehen sich auf die technische Neuerung der zusätzlichen Freischliffe am Sägeblatt, sowie auf den Feilenschliff mit/ohne Raspelung.Refer to protection claims on the technical innovation of the additional clearances on the saw blade, as well as the file sharpening with / without rasping.
