    摘要： This invention relates to methods and instruments for performing a surgical procedure in a disc space between adjacent vertebrae. The instruments include a distractor and a cutting instrument. In one embodiment the distractor includes a body portion and a pair of flanges extending along opposite sides of the body portion such that a slot is formed between the flanges and the body portion. The cutting instrument is positionable over the body portion and into the slots of the distractor so that the flanges are positioned between the cutting instrument and the adjacent tissue.

    摘要： A hand-held instrument, with a rotary power input to a camshaft, has cam and follower arrangement to provide a reciprocating shaft output. A cutter is provided on the output shaft. In one example, rotating cam percussion is transmitted to the cutter by engaging the cutter with the tissue to be cut, and pushing the instrument forward toward the cutter. In another example, rotating cam percussion is transmitted to the cutter by engaging the cutter with the tissue to be cut, and pulling the instrument back toward the user while maintaining engagement of the cutter with the tissue. In both examples, the cutter remains in idle condition until an axially directed load, forward in the one example, or backward on the other example, is placed on the cutter by moving the instrument forward or backward, respectively, while the camshaft is rotating. A distractor with frame is used to spread and maintain space between vertebral bodies, enabling entrance of the cutter.

    摘要翻译： 具有旋转动力输入到凸轮轴的手持式仪器具有凸轮和从动装置，以提供往复轴输出。 在输出轴上设有切割器。 在一个示例中，旋转凸轮敲击通过将切割器与要切割的组织接合而传送到切割器，并将仪器向前推向切割器。 在另一示例中，旋转凸轮敲击通过将切割器与要切割的组织接合而传送到切割器，并且在保持切割器与组织的接合的同时将仪器拉回用户。 在这两个例子中，刀具保持怠速状态，直到在凸轮轴旋转时，通过分别向前或向后移动仪器，将一个示例中向前的另一个示例的向后定向的负载或另一个示例的向后方放置在切割器上。 骨架牵引器用于扩张和维持椎体之间的间隙，从而能够切割刀具。
