ABSTRACT:
A guidance system and method for accurately reproducing surgical approach angles for increasing the efficiency and accuracy of image-guided biopsy procedures which require high levels of precision with respect to the orientation of surgical instruments prior to insertion. A tri-axial structure mounted in the vicinity of the patient provides a laser light beam to the point of incision on the surface of a patient. The orientation of this laser light beam serves as a guide for not only the location of the entry point of the surgical instrument but also the orientation of the surgical instrument during insertion. A range finding structure positioned in parallel with the tri-axial mounted structure provides an indication of the depth of insertion of the surgical instrument.
