Claim:
A system for positioning components in surgical procedures comprising; a surgical instrument support having a support body comprising a first member and second member having parallel portions extending in a first direction; a support body collar mounted to the first member and translatable along the first member; a support body collar locking mechanism to selectively inhibit translation of the support body collar; a linkage coupled to the support body collar translatable relative to the support body collar perpendicular to the first direction; a linkage locking mechanism to selectively inhibit translation of the linkage relative to the support body collar; a crossbar coupled to the support body collar and extending between the first member and the second member; a sleeve collar coupled to the linkage by a connection that allows polyaxial rotation of the sleeve collar relative to the linkage, wherein the sleeve collar is sized to receive an extender sleeve for installing bone anchors and allow the extender sleeve to translate in the sleeve collar; a sleeve collar locking mechanism to inhibit rotation of the sleeve collar; an extender sleeve locking mechanism to inhibit translation of the extender sleeve in the sleeve collar.
