1. A system for estimating an orientation, the system comprising:
- a base attached to a bone of a patient;
a surgical instrument mechanically coupled to the base;
a mechanism configured to adjust a relative position of the surgical instrument with respect to the base;
a first orientation sensor coupled to the base and configured to detect information indicative of an orientation of the bone;
a second orientation sensor coupled to the surgical instrument and configured to detect information indicative of an orientation of the surgical instrument; and
a processor communicatively coupled to the first and second orientation sensors and configured to;
receive information indicative of an orientation of an anatomic axis or plane of the bone; and
estimate an angle between the surgical instrument and the anatomic axis or plane.

Abstract
A system and method is provided for estimating orientation and position of surgical instrumentation or tools relative to a patient'"'"'s bone structure. The system and/or method may include registering an axis and/or plane associated with a patient'"'"'s bone. The system and/or method may further include receiving, from magnetic and orientation sensors, information indicative of orientation and position of the surgical instrument or tool relative to the registered axis and/or plane.

7. A system for estimating a position, the system comprising:
-
a base attached to a bone of a patient; a surgical instrument mechanically coupled to the base; a mechanism configured to adjust a relative position of the surgical instrument with respect to the base; a magnetic field generator attached to one of the surgical instrument or the base; one or more magnetic sensors coupled to the other of the base or the surgical instrument and configured to detect information indicative of a position of the surgical instrument; and a processor communicatively coupled to the magnetic sensors and configured to; receive information indicative of a first position of the surgical instrument relative to an anatomic surface of the bone; and estimate change in position of the surgical instrument relative to the anatomic surface of the bone. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)
