摘要： A distractor for separating adjacent elements, such as vertebrae. The distractor preferably has a scissors-type distracting mechanism, either in a simple scissors or double-acting scissors configuration. Additionally, one or more of the blades, distracting mechanism, and handles are offset with respect to the other to facilitate visualization and to increase the space available for an implant holder. The blades are configured to enhance versatility of the distractor. In a first embodiment, the blades are removable from the jaws of the distractor such that different blades may be used depending on the patient and situation with which the distractor is to be used. In a second embodiment, curved portions are provided between the blades and jaws such that the blades are offset from the jaws in a smooth transition which does not expose sharp edges to internal organs or vasculature of the patient. In a third embodiment, a pair of blades is provided on each jaw such that an implant may be inserted between the spaced apart blades without having a blade engage an external blade-receiving slot in the implant.
摘要翻译：分离相邻元素（如椎骨）的分心器。牵引器最好具有剪刀式的分散机构，无论是用简单的剪刀还是双作用的剪刀结构。另外，一个或多个刀片，分散机构和手柄相对于另一个偏移以便于可视化并增加可用于植入物保持器的空间。刀片配置为增强分离器的多功能性。在第一实施例中，刀片可从牵开器的钳口移除，使得可根据患者和牵引器将被使用的情况使用不同的刀片。在第二实施例中，在刀片和钳口之间设置弯曲部分，使得刀片在平滑的过渡部分偏离钳口，所述平滑过渡不会将尖锐边缘暴露于患者的内部器官或脉管系统。在第三实施例中，在每个钳口上提供一对刀片，使得植入物可以插入在间隔开的刀片之间，而不需要刀片接合植入物中的外部刀片接收槽。

摘要： The inter-vertebral implant consists of a frame-like cage enclosing a space, with a top and bottom surface, two side surfaces, a front and a rear wall. The top and bottom surfaces have a plurality of perforations, the total area of which amounts to 40 to 55 % of the total area of said surfaces. The individual area of a single perforation is at most 20 % of the total area of the top and bottom surfaces. The ratio VH/VK between the volume VH of the space and the total volume VK of the cage is in the range from 70 to 90 %. The cage is substantially wedge-shaped with top and bottom surfaces diverging towards the front wall. This gives the advantage that, owing to the large bone bearing area of the top and bottom surfaces, the implant is prevented from sinking into the end plates of the body of the vertebra.

摘要： The inter-vertebral implant consists of a frame-like cage (1) enclosing a space (20), with a top and bottom surface (11, 12), two side surfaces (13, 14), a front (16) and a rear wall (15). The top and bottom surfaces (11, 12) have a plurality of perforations (24), the total area of which amounts to 40 to 55 % of the total area of said surfaces (11, 12). The individual area of a single perforation (24) is at most 20 % of the total area of the top and bottom surfaces (11, 12). The ratio VH/VK between the volume VH of the space (20) and the total volume VK of the cage (1) is in the range from 70 to 90 %. The cage (1) is substantially wedge-shaped with top and bottom surfaces (11, 12) diverging towards the front wall (16). This gives the advantage that, owing to the large bone bearing area of the top and bottom surfaces, the implant is prevented from sinking into the end plates of the body of the vertebra.
