Abstract
Description
Gekrümmter Knochennagel Die Erfindung betrifft einen gekrümmten Knochennagel zum Ausrichten der Knochenteile von gebrochenen menschlichen Oberschenkeln im proximalen Bereich, wonach der distale Bereich mit einer aus dem Knochen herausragenden Abflachung versehen ist, Dieses Bekannte wird erfindungsgemäß durch das Bessere ersetzt, wonach die Abflachung am Ende des Nagels kreisrunden Profils von einer Platte bzw. einem Plattenstück gebildet, zoBo angequetscht ist, von der bzw, von dem eine der beiden Plächen eine Nagelmantellinie tangiert bzw, ausserhalb von dieser verläuft, Der Erfinder dieser îlassnaffllle entnahm dem Verhalten der Patienten, dass das aus dem Knochen herausragende Nagelende Beschwerden bereitet, Diese gehen möglichweise davon aus, dass bei Bekanntem (zoBo Knochennägel nach OS 2 341 439) die spezifischen Drucke zu hoch sind, mit denen das Nagelende am Knochen anliegt, Das Ziel der Erfindung besteht darin, die Auflage der Platte auf dem Knochen stufenlos auf den Nagel schaft und bzw, oder auf einen Endzapfen übergehen zu lassen, ferner die mutmaßliche D{ickabertragungsfläche optimal gross zu gestalten0 Die Platte kann auf das Nagelende aufgeschweisst oder aber auch kippbar gelenkig auf dem Nagelende axial gesichert befestigt ein in breiterer Ausgestaltung der Erfindung ist die Platte kreisrund oder - von der Nagelachse aus gesehen -innen konkav und demnach aussen konvex gewölbt, z>BO in Kombination mit der Anregung, dass der aus dem Knochen herausragende Teil in ein sehr kurzes Zylinderstück des Nagelprofils endet, Von der Zeichnung werden Ausführungsbeispiele geoffenbart, Die Fig 1 und 2 zeigen eines in Draufsicht und in Seitenansicht, ebenso die Fig 3 und 4, beide einstückig. Die Fig 5 und 6 veranschaulichen eine Variante mit auf das abgeplattete Nagelende aufgelöteter Druckplatte 2 die nach der Draufsicht von Fig 7 länglich geformt ist, jedoch nach den Fig 8 und 9 (Draufsicht und Seitenansicht) kreisrund gestaltet ist, Die Fig 10 und 11 zeigen (in Draufsicht und Seitenansicht) eine von der zylindrischen Verdickung gegen axiales Verschieben gesicherte, mittels der Krägen 2a, 2b drehbar gelagert Platte, was auch dem Querschnitt nach Fig 12 entnehmbar ist, Die Fig 13, 14 und 12 stellen Querschnitte von weiteren Varianten dar, Immer ist die Knochenanlagefläche Plan oder von der Nagel achse aus diametral gesehen (im Gegensatz zu Bekannten) nach aussen abgesetzt0 Dies gilt auch für das besonders interessante Ausführungsbeispiel nach Fig 15, bei der sich die :!wölbung der an das Nagelende angeschweissten Platte 2 der Knochenkontur angeglichen isto In allen Fällen ist das Nagelhandhabegerät des Chirurgen besonders leicht ansetzbar, Curved Bone Nail The invention relates to a curved bone nail for aligning the bone parts of broken human thighs in the proximal Area, after which the distal area with a flat protruding from the bone is provided, this known is replaced according to the invention by the better, after which the flattening at the end of the nail circular profile of a plate or a Plate piece is formed, zoBo is squeezed by or by which one of the two Plächen is tangent to or outside of a nail jacket line, which The inventor of this îlassnaffllle inferred from the behavior of the patient that this came from the bone causes protruding nailing complaints, these may go it is assumed that the specific Pressures are too high with which the nail end rests against the bone, the aim of the invention consists in placing the plate on the bone steplessly on the nail shaft and or, or to pass over to an end pin, furthermore the presumed thickness transfer surface to make it optimally large0 The plate can be welded onto the end of the nail or also tiltably articulated attached axially secured to the nail end In a broader embodiment of the invention, the plate is circular or - of the Seen from the nail axis - concave on the inside and therefore convex on the outside, z> BO in combination with the suggestion that the part protruding from the bone in a very short cylinder section of the nail profile ends, from the drawing are exemplary embodiments disclosed, Figures 1 and 2 show one in plan view and in side view, as well Figures 3 and 4, both in one piece. FIGS. 5 and 6 illustrate a variant with pressure plate 2 soldered onto the flattened nail end according to the plan view 7 is elongated, but according to FIGS. 8 and 9 (top view and side view) is designed circular, The Figures 10 and 11 show (in plan view and side view) one of the cylindrical thickening against axial displacement secured, rotatably mounted by means of the collars 2a, 2b plate, which also the cross-section according to Fig. 12 can be removed, Figs. 13, 14 and 12 represent cross-sections of further Variants represent, the bone contact surface is always plan or from the nail axis seen diametrically (in contrast to acquaintances) set off from the outside0 This also applies for the particularly interesting embodiment according to FIG. 15, in which the :! The curvature of the plate 2 welded to the end of the nail is adjusted to the bone contour isto In all cases, the surgeon's nail handling device is particularly easy to attach,
