1. A device for positioning an infrared tracking member relative to implanted surgical implants, comprising:
- a first elongated element comprising a proximal portion of the device, the first elongated element comprising a proximal end and a distal end, the proximal end comprising an attachment element for attaching the infrared tracking member to the device, the distal end comprising a recess;
a second elongated element linearly aligned with the first elongated element and comprising a middle portion of the device, the second elongated element having a proximal elongated shaft segment and a distal elongated shaft segment and a guide pin extending laterally away from the second elongated element, the proximal elongated shaft segment having a proximal end comprising a cavity formed within the proximal end and a retention element, the retention element configured to engage the recess, the distal elongated shaft segment having a distal end comprising an attachment feature configured to engage a surgical implant;
wherein the first elongated element is independently rotatable of the second elongated element; and
a third elongated element linearly aligned with the second elongated element and comprising a distal portion of the device, wherein the third elongated element has a track housing configured to receive the guide pin on the second elongated element, and wherein the second and third elongated elements are slideably associated with one another through movement of the guide pin in the track housing.
