BONE CUTTING JIG SYSTEM FOR SPINAL IMPLANT
Abstract:
A bone cutting jig system (10,30) for forming and shaping spinal implants (24) is shown. The system includes a first cutting jig (10,30) having a bed (11,31) with a clamp mechanism (12,36) for clamping donor bone (13,24) positioned on the bed (11,31). A cutting guide insert (15) or plate (35) is received in fixed orientation on the bed (11,31) and is further provided with two or more spaced cutting blade cutting guides (18, 19 or 42) which are configured for transversely cutting out a segment of the donor bone (13, 24) with a reciprocating saw or router to a predetermined shape to provide a custom fit lumbar, cervical or thoracic inter-body fusion implant. A second cutting jig (80) is provided for making additional cuts to the preformed implant (24, 81) for custom fit to particular implant applications.
Abstract(Chinese):

示出了用于形成和成形脊柱植入物（24）的骨切割夹具系统（10,30）。 所述系统包括具有床（11,31）的第一切割夹具（10,31），所述床具有用于夹紧位于所述床（11,31）上的供体骨（13,24）的夹紧机构（12,36）。 切割导向插入件（15）或板（35）以固定的方式容纳在床（11,31）上，并且还设置有两个或更多个间隔开的切割刀片切割引导件（18,19或42），其被构造成横向 用往复锯或路由器将供体骨（13,24）的一段切割成预定的形状，以提供定制的腰椎，宫颈或胸部体间融合植入物。 提供了第二切割夹具（80），用于对预成型的植入物（24,81）进行额外的切割，以定制适合于特定的植入物应用。
