摘要:
An implant for therapeutically separating bones of a joint has two endplates each having an opening through the endplate, and at least one ramped surface on a side opposite a bone engaging side. A frame is slideably connected to the endplates to enable the endplates to move relative to each other at an angle with respect to the longitudinal axis of the implant, in sliding connection with the frame. An actuator screw is rotatably connected to the frame. A carriage forms an open area aligned with the openings in the endplates. The openings in the endplates pass through the carriage to form an unimpeded passage from bone to bone of the joint. The carriage has ramps which mate with the ramped surfaces of the endplates, wherein when the carriage is moved by rotation of the actuator screw, the endplates move closer or farther apart.
摘要(中):
用于治疗分离关节骨的植入物具有两个端板,每个端板具有通过端板的开口,以及在与骨接合侧相对的一侧上的至少一个斜面。 框架可滑动地连接到端板,以使终板能够相对于植入物的纵向轴线以一定角度相对于框架滑动连接地移动。 致动器螺钉可旋转地连接到框架。 托架形成与端板中的开口对准的开放区域。 端板中的开口穿过托架以形成从关节的骨头到骨头的无阻碍通道。 滑架具有与端板的斜坡表面配合的斜面,其中当滑架通过致动器螺杆的旋转而移动时,端板移动得更近或更远。
