摘要： The invention concerns an intervertebral implant in the form of a supporting body (1) comprising a central crosspiece (2) and two lateral parts (3, 4) integral with said central crosspiece (2) and forming one single piece therewith. The lateral parts (3, 4) are arranged in two planes (5, 6) extending substantially parallel to each other and separated by the crosspiece (2), and can be applied, as supporting surface, on adjacent vertebral elements. The crosspiece comprises a hollow guide cylinder (7) extending substantially parallel to the lateral parts (3, 4) and between them, and comprises at least one thread (8; 28). A spacing device can be inserted between the lateral parts. The intervertebral implant provides several advantages as follows: the natural lordosis radius of the spine can be specifically restored in a patient, and this angle can be determined before the operation, thereby obtaining for the implant, optimal initial conditions for internal growth; an atraumatic insertion technique is used, since the implant can be delicately screwed and in controlled manner instead of being countersunk; and a simplified operation technique in three stages can be used (also with minimal collapse) by using a guide rod.
摘要翻译：椎间植入物具有支撑体（1）的形式，该支撑体包括中央腹板（2）和与腹板（2）一体连接的肢体（3,4）。腿（3,4）以两个基本上相互平行的方式布置，穿过腹板（2）间隔开的平面（5,6），这些平面可以用作相邻椎体的支撑表面。腹板（2）具有基本上平行于腿（3,4）并且在这些具有至少一个螺纹（8; 28）的中空导向筒（7）之间延伸。在腿之间，可以引入扩散装置。本发明的椎间植入物具有以下优点：脊柱的天然脊柱前凸半径可以恢复到患者，并且该角度可以在术前确定; 这导致种植体向内生长的最佳条件; 一种无创伤性插入技术，其中植入物可以以受控的方式轻柔地拧入，而不是冲击过程; 和简化的（也是微创）导针3步外科技术。

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。
