Patent ID: 8491599

Claim:
A surgical guide for aiming at least one tool toward a surgical target, the guide having a guide reference plane, the surgical guide comprising: a base having a base thickness, a base width disposed within the reference plane, a track cut through the base thickness, the track having a uniform track width, the track having a constant track curvature so as to define a base arc of a base circle, the base circle oriented within the reference plane, the base having a base channel cut through the base width, the base channel disposed within the reference plane, the base channel sized and shaped so as to be capable of accepting a locator tool therethrough; and at least one member sized so as to be receivable in the track to engage with the base, the at least one member having a constant member curvature equal to the constant track curvature so as to define a member arc of a member circle, so that, when engaged with the base, the member arc is disposed within a member arc plane that is oriented orthogonal to the reference plane, the base circle and the member circle defining a sphere having a sphere center located at the surgical target, the at least one member having a member channel cut through the member, the member channel disposed within the member arc plane, the member channel sized and shaped so as to be capable of accepting the at least one tool therethrough, such that when the at least one member is engaged with the base, both the base channel and the member channel are aligned toward the surgical target.
