    • An instrument for use with a surgical navigation system to aid in cutting a bone is provided. The instrument includes an anchoring block configured for attachment to a bone and a cutting block or guide having a cutting slot or other guiding surface. The cutting block is also configured for attachment to a bone. A connecting member connects the anchoring block to the cutting block and permits the cutting block to move relative to the anchoring block within a pre-determined range of motion. The connecting member also prevents movement of the cutting block relative to the anchoring block beyond the pre-determined range of motion. In certain embodiments, the connecting member can be configured to provide resistance to movement of the cutting block relative to the anchoring block, such that the cutting block can maintain its position without being held by the physician.
    • 提供了一种与外科导航系统一起使用以帮助切割骨骼的仪器。 仪器包括被配置为附接到骨骼的锚固块和具有切割槽或其它引导表面的切割块或引导件。 切割块还构造成用于附接到骨骼。 连接构件将锚固块连接到切割块,并允许切割块相对于锚定块在预定的运动范围内移动。 连接构件还防止切割块相对于锚固块移动超过预定的运动范围。 在某些实施例中,连接构件可被构造成提供抵抗切割块相对于锚定块的移动的阻力,使得切割块可以保持其位置而不被医师保持。
