Trackable guide for surgical tool

摘要

A surgical guide for use with an image guided surgery includes first and second surfaces (111,113). At least three signaling devices such as infrared emitters (4a-4d) are disposed on the first surface (111), and a cylindrical mounting boss (104) is disposed on the second surface (113). A guide aperture (106) is perpendicular to the first and second surfaces and extends between them. The guide aperture is configured to support a surgical tool such as a biopsy needle. A sleeve may be placed in the aperture to support additional tools.
