Description
TECHNISCHES GEBIET TECHNICAL AREA
Die vorliegende Erfindung bezieht sich auf ein spannbares Implantat zur Verwendung bei der Minimal-Invasiven Chirurgie (MIC), welches mit einem symmetrischen Aufbau der Verbindungsstange ausgebildet ist und damit eine Streckwirkung erzeugbar ist, so dass dessen Positionierstift und spannbare Klemmelemente gegenüber der Implantatposition eine unterseitige und seitliche Anpresswirkung erzeugbar ist, um das Implantat vorzugsweise zu positionieren und implantieren, um eine verbesserte Rekonstruktion und damit einhergehend eine verbesserte Aufbauverstärkung des Knochengewebes zu erzielen. The present invention relates to a tensionable implant for use in minimally invasive surgery (MIC), which is formed with a symmetrical construction of the connecting rod and thus a stretching effect can be generated, so that its positioning pin and tensionable clamping elements relative to the implant position, a lower and lateral pressure can be generated in order to position and implant the implant preferably, in order to achieve an improved reconstruction and, consequently, an improved structural reinforcement of the bone tissue.
