Abstract

Trackable retractor systems, apparatuses, devices, and methods involving: retractor blades, each retractor blade having a proximal end and a distal end, the retractor blades having a blade axis defined by a midline therebetween or thereamong; actuation arms, each actuation arm having a proximal end and a distal end, each actuation arm distal end configured to correspondingly couple with each retractor blade proximal end, and each actuation arm configured to correspondingly actuate each retractor blade; a positioning arm configured to position each actuation arm; a movable clamp configured to movably couple with the positioning arm and one actuation arm and to move the one actuation arm relative to another actuation arm; and three distinct tracking features disposed in a tracking plane, two distinct tracking features configured to correspondingly couple with the retractor blade proximal ends, one other distinct tracking feature configured to couple with the movable clamp, and each distinct tracking feature having a distinct tracking token, whereby the blade axis is maintained in a position orthogonal to the tracking plane, and whereby optical alignment is maintained along the blade axis in relation to a desired focal depth.
