Kind Code:
A
Abstract:
A radiolucent halo-type retractor ( 20 ) having a radiolucent curvilinear fixed member ( 32 ) connected to a radiolucent curvilinear movable member ( 34 ). Each of the fixed and movable members has a radiolucent male coupling ( 44, 46 ) projecting outward from a convex surface ( 40, 42 ) to receive a female coupling of a retractor arm. The ends ( 60, 68 ) of the movable member are separated by a distance less than a distance separating the ends ( 56, 64 ) of the fixed member. Radiolucent starburst connectors ( 58, 62 ) are disposed on first ends of the fixed and movable members to secure the fixed and movable members at a desired angular orientation. Radiolucent starburst connectors ( 66, 70 ) are also disposed on second ends of the fixed and movable members to secure the fixed and movable members at a desired angular orientation. A pin ( 72 ) rotatably connects the first ends. A locking shaft ( 76 ) rotatably connects the second ends and is operable to lock the fixed and movable members in a desired orientation.
