Method and system for computer assisted surgery
First Claim
1. A method for computer assisted orthopedic feedback of at least one surgical instrument relative a pre-operative plan, wherein the surgical instrument is moveable relative to a patient structure during surgery;
- the pre-operative plan including a virtual structure, which is a virtual representation of the patient structure;
comprising;
providing the pre-operative plan including planned position and orientation of an implant relative to the virtual structure;
obtaining a position of the patient structure using a surgical navigation system;
obtaining a position of at least one surgical instrument using the surgical navigation system;
registering the patient structure to the virtual structure;
tracking a current position and orientation of the at least one surgical instrument relative said patient structure using the surgical navigation system; and
providing feedback of the current position and orientation of the at least one surgical instrument relative to the planned position and orientation of the implant based on the tracked current position and orientation of the at least one surgical instrument.

Abstract
A method and system for computer assisted orthopedic feedback of at least one surgical object relative a pre-operative plan are disclosed. The pre-operative plan includes a virtual object, which is the virtual representation of the surgical object, and a virtual structure, which is the virtual representation of the patient structure. The method comprises providing the pre-operative plan including planned position and orientation of the virtual object relative to of the virtual structure; obtaining the position of the patient structure based on a surface of the patient structure using a surgical navigation system; obtaining the position of the surgical object using the surgical navigation system; registering the patient structure to the virtual structure and the surgical object to the virtual object; tracking a current position and orientation of the surgical object using the surgical navigation system; and providing feedback of a current position and orientation of the surgical object relative to the planned position and orientation of the virtual object based on the tracked current position and orientation of the surgical object.
