Support for locating instrument guides
First Claim
1. A surgical instrument system for resecting a bone during joint arthroplasty, the system comprising:
- a cutting instrument;
an anchoring structure;
a guide structure for guiding the path of the cutting instrument; and
an articulating linkage connecting the anchoring structure to the guide structure, the articulating linkage including a plurality of lockable ball joints arranged in series, each ball joint providing for freedom of movement about three axes of rotation.

Abstract
A surgical instrument system includes a cutting instrument, an anchoring structure, a guide structure and an articulating linkage. The anchoring structure can be fixed to a reference or benchmark, such as a location on the patient'"'"'s bone. The articulating linkage connects the anchoring structure to the guide structure and includes a plurality of lockage ball joints arranged in series. Each ball joint provides for freedom of movement about three axes of rotation. The articulating linkage may include other structures allowing for additional rotational and translational degrees of freedom of movement for the guide structure with respect to the reference or benchmark. The system is useful in positioning, aligning and orienting a cutting block in joint arthroplasty, and may be useful in conjunction with computer assisted surgery. The system may also include computer navigation trackers for use in such computer assisted surgery.
