Abstract
A retractor with a specialized blade head assembly. The blade head assembly has a central plate. The central plate extends between a first side edge and a second side edge. A first rotatable arm is attached to the first side edge with a first hinge joint. A second rotatable arm is attached to the second side edge with a second hinge joint. Both rotatable arms can be rotated about the hinge joints. Both the first hinge joint and the second hinge joint are friction hinges that require a threshold force to move. An elongated shaft interconnects with the central plate at a pivot joint. The elongated shaft can be attached to the blade head assembly after the blade head assembly has been inserted into a patient's body.
