A fastening system for securing a retractor having a docking pin to a retractor support arm, the fastening system comprising:
- a housing rotatably attached to the retractor support arm and including a slotted aperture;
- a docking unit slidably engaging and being disposed at least partially within the housing, the docking unit including a docking aperture adapted for receiving the docking pin of the retractor;
- and
- a travel pin extending from the docking unit and engaging the slotted aperture and thereby defining the amount of travel of the docking unit with respect to the housing.
A fastening mechanism for securing a retractor having a docking pin to a positioning arm, the fastening system comprising:
- a housing rotatable attached to the positioning arm and having a slotted aperture;
- a docking unit slidably engaging and being at least partially disposed within the housing;
- a travel pin extending from the docking unit and engaging the slotted aperture and thereby defining the amount of travel of the docking unit with respect to the housing;
- and
- wherein the housing and the docking unit frictionally engage the docking pin of the retractor through movement of the docking unit with respect to the housing thereby retaining the retractor in a selected position.
