摘要： Cutters for disrupting tissue include a cutter body and replaceable cutter blades. The cutter blades may be placed in one of three positions (sheathed for transport, unsheathed for use, and sufficiently exposed for blade exchange) by the relative movement of a cutter sheath with respect to the engagement zone between the cutter blade and the cutter body. The relative movement of the cutter sheath may be limited to an operational range to preclude inadvertent exposure of the cutter blade to prevent unintended disengagement from the cutter body. Various sheath limiters are disclosed that selectively limit movement of the cutter sheath to an operational range or allow extraordinary movement to allow blade exchange. In some instances other intermediate stops may be used to further limit the relative motion. The relative motion could be imparted by the movement of a cutter rod and thus limited by a rod limiter.

摘要： Instrumentation systems that facilitate the reproducible deployment and placement of fixation device such as a screw, via an aligned, percutaneous access and approach, designed to relieve lower back pain and possibly improve disc health and prevent progression or transition of disease. Information about methods and equipment for accessing and preparing bone for subsequent delivery of a bone screw such as a facet screw across a facet joint. Some of the many teachings contained herein address a system of visual indicators may be used in connection with a bore cutter that operates around an anchored guide wire to avoid dislodging the anchored guide wire.

摘要翻译：用于破坏组织的切割器包括切割器主体和可替换的切割刀片。切割刀片可以通过刀片相对于切割刀片和切割器主体之间的接合区域的相对运动而被放置在三个位置中的一个位置（护套用于运输，未使用并且被充分暴露用于刀片更换）。切割器护套的相对运动可以被限制在操作范围内，以防止切割刀片的意外暴露以防止切割器主体意外脱开。公开了各种护套限制器，其选择性地限制切割器护套的移动到操作范围，或允许非凡的运动以允许刀片更换。在一些情况下，可以使用其它中间止挡件来进一步限制相对运动。可以通过切割杆的运动来赋予相对运动，并由此限制杆限制。
