Description

Universell anwendbarer Marknagel mit zugehörigem Zielgerät Universally applicable intramedullary nail with associated target device
Beschreibung:Description:
Das Universalimplantatsystem gehört zu den biomechanischen Hilfsmitteln der Medizintechnik zur Versorgung von Knochenbrüchen an Röhrenknochen. Dem Stande der Technik entsprechend werden schwerer Knochenbrüche an Röhrenknochen durch Öffnen der Knochen an einem Ende und Einbringen eines sogenannten Marknagels, welcher verspreizt bzw. mittels Schrauben, die durch Bohrungen quer zur Nagelachse hindurch in den Knochen geschraubt werden, verriegelt wird. Es haben sich verschiedenste Bauformen entwickelt, welche spezialisiert auf Oberarm, Ober - bzw. Unterschenkel anwendbar sind. Aus Gründen der wirtschaftlichen Lagerhaltung und Vereinheitlichung und damit Vereinfachung der Anwendbarkeit ist ein Universalimplantatsystem, welches an allen 3 Röhrenknochen anwendbar ist wünschenswert. Dies wird mit dem Universalimplantatsystem wie folgend beschrieben erfindungsmäßig gelöst:The universal implant system is one of the biomechanical aids of medical technology for the treatment of broken bones on long bones. In accordance with the prior art, severe bone fractures on tubular bones are opened by opening the bones at one end and introducing a so-called intramedullary nail, which is spread apart or locked by means of screws which are screwed into the bone through holes transverse to the nail axis. A wide variety of designs have developed which can be used for the upper arm, upper leg and lower leg. For reasons of economical storage and standardization and thus simplification of the applicability, a universal implant system which can be used on all 3 long bones is desirable. This is solved according to the invention with the universal implant system as described below:
Der Universalmarknagel (1) dient zur Versorgung von komplexen Brüchen des Oberarmes, Oberschenkels und Unterschenkels. 5 Bohrungen im proximalen und 3 im distalen Nagelende sollen eine Verriegelung in der Sagital- und Frontalebene des jeweiligen Knochenendes ermöglichen. Im proximalen Ende befindet sich eine sagittale dünne Bohrung (2) für die Verriegelung am Oberarm- bzw. Schienbeinkopf. Die Bohrung (3) und (5) dienen der Verriegelung des Oberarm- bzw. Schienbeinkopfes in der Frontalebene und sind dicker ausgeführt. Die Bohrungen (4) und (6) sind noch dicker ausgeführt und nehmen Schrauben zur Fixierung des Schenkelhalses am Oberschenkel in der Sagita- lebene unter einem Winkel von 120°- 140° auf. Am distalen Nagelende (12) finden sich eine dünne - Bohrung (10) in der Sagittal- und zwei dünne Bohrungen (9,11) in der Frontalebene für die Aufnahme von Schrauben im Oberarm- und Schienbeinende bzw. im Oberarm-, Oberschenkel-und Schienbeinende. Das Proximale Nagelende ist beginnend distal der Bohrung (6) verdickt ausgeführt. Eine 6°- 12°- Krümmung leitet auf den dünneren, runden Schaft über. Die Nagellängen reichen von 200 - 400mm und sind in Schritten gestuft. Das Universalzielgerät (15) dient der Verriegelung des proximalen Nagelendes. Es wird so auf den Nagel aufgesetzt, daß es mit seiner Orientierungszunge (25) in die Orientierungsnut des Nagels (14) paßt. Eine spezielle Schraube (16) fixiert es im Innengewinde (13) des Nagels (1).The universal intramedullary nail (1) is used to treat complex fractures of the upper arm, thigh and lower leg. 5 holes in the proximal and 3 in the distal nail end should allow locking in the sagital and frontal plane of the respective bone end. There is a sagittal thin hole (2) in the proximal end for locking the upper arm or shin head. The holes (3) and (5) are used to lock the upper arm or shin head in the frontal plane and are thicker. The holes (4) and (6) are made even thicker and accommodate screws for fixing the femoral neck to the thigh in the sagita plane at an angle of 120 ° - 140 °. At the distal nail end (12) there is a thin hole (10) in the sagittal and two thin holes (9, 11) in the frontal plane for receiving screws in the upper arm and shin end or in the upper arm, thigh and Shin ends. The proximal nail end is thickened starting distal to the hole (6). A 6 ° - 12 ° curve leads to the thinner, round shaft. The nail lengths range from 200 - 400mm and are graded in steps. The universal aiming device (15) is used to lock the proximal nail end. It is placed on the nail so that it fits into the orientation groove of the nail (14) with its orientation tongue (25). A special screw (16) fixes it in the internal thread (13) of the nail (1).
Diese Schraube hat einen gerändelten Kopf (23), welcher dem händischen Festziehen der Schraube und dem Einschlagen des Nagels dient. Unterhalb des Kopfes befindet sich ein Sechskant (24) zum Festziehen der Schraube. Die Bohrhülsenführungen (17, 18, 19) dienen der Aufnahme von Schraubhülsen (26) und Bohrhülsen (27) zum Setzen von Verriegelungsschrauben in der Frontalebene an Oberarm bzw. Oberschenkel und in der Sagittalebene am Schienbeinkopf. Die Bohrhülse-ifli rungen (21, 22) sind zur Verriegelung in der Frontalebene am Schienbeinkopf vorgesehen und befinden sich an einem für rechts und links (Schienbeinkopf!) umsetzbaren Querbügel (20) des Zielgerätes, der mit den Schrauben (28.) und Paßstift (31) auf der benötigten Seite fixiert wird. Ein Griffstück (29) dient dem Halten des Zielgerätes. This screw has a knurled head (23), which is used to tighten the screw by hand and drive in the nail. There is a hexagon (24) below the head for tightening the screw. The drill sleeve guides (17, 18, 19) serve to accommodate screw sleeves (26) and drill sleeves (27) for setting locking screws in the frontal plane on the upper arm or thigh and in the sagittal plane on the shinbone head. The drill sleeve-ifli stanchions (21, 22) are intended for locking in the frontal plane on the shinbone head and are located on a crossbar (20) of the aiming device that can be implemented for right and left (shinbone head!), Which is secured with the screws (28.) and dowel pin (31) is fixed on the required side. A handle (29) is used to hold the target device.
