Guidance system for rotary surgical instrument |
摘要 |
A surgical instrument for use in a computer assisted navigation system is provided. The instrument includes at least one reference element registerable in the navigational system disposed on a mounting assembly. The mounting assembly is rotatably mounted on the instrument and includes a counterweight or other anti-rotation feature whereby the reference element may be maintained in a desired orientation. A rotatable shaft may extend through the mounting assembly and have one end which is securable to a rotary driver such as a drill and a second end securable to a rotary tool such as a reamer. The second end of the shaft may utilize a collet assembly to firmly grasp the driven tool and thereby limit relative movement of the tool and the reference elements disposed on the mounting assembly. <IMAGE> |
