Description

Werden quer elastische Innenschienen für Knochenbrüche nach Patent 742 097, sogenannte Knochenmarknägel, aus einem harten Material hergestellt, so brechen sie oft, während sie sich hei Herstellung aus einem weichen Material verbiegen. Are transversely elastic inner splints for bone fractures according to patent 742 097, so-called bone marrow nails, made of a hard material, see above they often break while bending when made from a soft material.

Gemäß vorliegender Erfindung wird eine erhebliche Verbesserung dadurch erreicht, daß eine aus verhältnismäßig weichem Material bestehende Schiene mit hartgeprägten Längsstreifen versehen wird, die ihr eine ausreichende Längsstabilität und Querelastizität verleihen. Die durch die Prägung gebildete gegliederte Oberfläche begünstigt überdies die Anpassung an den Querschnitt des Knochenkanais. In accordance with the present invention, there is thereby a significant improvement achieved that an existing made of relatively soft material rail with hard embossed Longitudinal strip is provided, which gives her sufficient longitudinal stability and transverse elasticity to lend. The structured surface formed by the embossing is also beneficial the adaptation to the cross-section of the bone canal.

Bei der Herstellung solcher Schienen kann man in verschiedener Weise verfahren. There are several ways of making such rails procedure.

Man kann z. B. der Schiene zuerst durch entsprechendes Biegen das gewünschte Profil (s.Fig. I bis I7), Z. B. als Schlitzrohr, geben und sie dann unter Benutzung eines eingeführten Dornes als Unterlage mit den Längseinprägungen a versehen. You can z. B. the rail first by bending accordingly Enter the desired profile (see Figs. I to I7), e.g. as a slotted tube, and then enter it under Use an inserted mandrel as a base with the longitudinal embossings a.

Oder man kann die Schiene in vorgeformtem Zustand prägen und dann fertig formen.Or you can emboss the splint in a pre-formed state and then finish shaping.

Statt dessen kann auch ein flacher Metallstreifen mit der Längsprägung versehen und dann die P rofilformung vorgenommen werden. Instead, a flat metal strip with the longitudinal embossing can also be used provided and then the profile shaping can be made.

Man kann auch, besonders in letzterem Fall, eine für mehrere Gebrauchslängen ausreichende Schiene maschinell, z. B. durch Ziehen oder Walzen, herstellen und mit den Prägestreifen versehen. Von einer solchen Schiene kann man dann im Einzelfall die benötigte Länge abschneiden. One can also, especially in the latter case, one for several usable lengths sufficient splint by machine, e.g. B. by pulling or rolling, produce and provided with the embossed strips. Such a rail can then be used on a case-by-case basis cut off the required length.

PATENTANSPRCHE: I. Quer elastische Innen schiene für Röhrenknochen, dadurch gekennzeichnet, daß sie durch Hartprägen verdünnte Längsstreifen aufweist. PATENT CLAIM: I. Cross elastic inner splint for long bones, characterized in that it has longitudinal strips thinned by hard embossing.

2. Verfahren zur Herstellung der Innenschiene nach Anspruch I, dadurch gekennzeichnet, daß die harten Streifen in der fertig oder fast fertig gebogenen Schiene, z. B. durch Prägen auf einem eingelegten Dorn, erzeugt werden. 2. A method for producing the inner rail according to claim I, characterized in that marked that the hard strips in the finished or almost finished bent Rail, e.g. B. by embossing on an inserted mandrel. 3. Verfahren zur Herstellung der Innenschiene nach Anspruch I, dadurch gekennzeichnet, daß die harten Streifen in die flache Schiene eingeprägt werden und erst später das Biegen in die Profilform erfolgt. 3. A method for producing the inner rail according to claim I, characterized in that characterized in that the hard strips are embossed into the flat rail and only later is the bending into the profile shape. 4. Verfahren zur Herstellung von Innenschienen nach Anspruch I, dadurch gekennzeichnet, daß eine für mehrere Gebrauchslängen ausreichende Schiene maschinell, z. B. durch Ziehen oder Walzen, hergestellt und mit den Prägestreifen versehen wird. 4. A method for the production of inner rails according to claim I, characterized characterized that a splint sufficient for several usable lengths is mechanically, z. B. by drawing or rolling, is produced and provided with the embossing strips.
