摘要： A method for aligning a resection guide relative to a patient's bone has applications during arthroplasty. An alignment guide is coupled to a patient's bone, to which there is coupled a resection guide. The resection guide is positioned along a transactional path and a plurality of rotational paths by manipulation of the alignment guide, thereby providing three degrees of freedom of manipulation over infinitely adjustable ranges.

摘要： A system for resecting a tibia and femur during arthroplasty includes anchoring devices, a three-way alignnment guide attachable to an anchoring device. The alignment guide provides for locating a resection guide in three degrees of freedom, including one translation and two rotations. The resection guide is coupled to a computer navigation system.

摘要： Tools for resecting tibia and femur include anchoring devices, a three-way alignment guide attachable to the anchoring devices, two embodiments of a resection guide attachable to the alignment guide and equipped with couplings for trackers, a plane probe for examining the resected plane, and apparatus for EM alignment of the resection guide in the event of a computer failure. The methods of the invention include operating a computer aided navigation apparatus in the conventional manner including attaching one or more trackers to the bone to be resected; choosing a location for the anchoring device with or without guidance from the computer and installing the anchoring device; attaching the three-way alignment guide to the anchoring device; attaching a resection guide to the alignment guide; attaching one or two trackers to the resection guide; locating the resection guide with the aid of the alignment guide and the computer; fixing the resection guide to the bone with pins. After the bone is resected, the resection plane probe may be attached to a tracker and moved about the resected plane to obtain feedback from the computer navigation system. In the event of computer failure, the methods include attaching the EM alignment guide to the resection guide; attaching the EM rod to the EM alignment guide; and locating the resection guide by visual location of the EM rod rather than by feedback from the computer navigation system.
摘要翻译：用于切除胫骨和股骨的工具包括锚固装置，可附接到锚固装置的三向对准导向件，可连接到对准引导件并配备有用于跟踪器的联接器的切除引导件的两个实施例，用于检查切除平面的平面探针，以及在计算机故障的情况下，切除指南的EM对准设备。本发明的方法包括以常规方式操作计算机辅助导航装置，包括将一个或多个跟踪器附接到要切除的骨骼上; 在有或没有来自计算机的引导下选择锚定装置的位置并安装锚定装置; 将三向对准引导件附接到锚定装置; 将切除引导件附接到对准引导件; 将一个或两个跟踪器附接到切除引导件; 借助于对准引导件和计算机定位切除引导件; 用针脚将切除指南固定到骨头。在切除骨后，切除平面探针可以附接到跟踪器并且围绕切除的平面移动以从计算机导航系统获得反馈。在计算机故障的情况下，所述方法包括将EM对准引导件附接到切除引导件; 将EM杆安装到EM对准导轨上; 并通过EM杆的视觉位置而不是来自计算机导航系统的反馈来定位切除指南。
