Abstract: A system for harvesting a tendon graft is disclosed, including a retractor, a guide and a harvesting tool. The retractor is collapsible and upon release, becomes self-supporting to hold open an anatomic space developed in a patient above the tendon. A guide assembles with the retractor to orient a guide shaft along the retractor and thereby the anatomic space. The harvesting tool includes a working end with a blade edge for cutting into the tendon. The harvesting tool defines a contoured surface for engaging and translating along the guide shaft while assembled to the retractor. The guide shaft and contoured surface limit the trajectory and translation extent of the harvesting tool along and into the tendon.
