1. An apparatus for supporting and positioning a patient's leg during a surgical procedure, the apparatus comprising:
a substantially rigid non-linear support structure;
a proximal locking swivel joint coupled to a proximal end of the support structure, wherein the proximal locking swivel joint holds the support structure in at least one position relative to a surgical table;
a gas piston assembly connected to the gas piston mounting element rigid non-linear support structure at a first piston end point and connected to the proximal end of the support structure at a second piston end point, wherein at least one of the first piston end point and the second piston end point is movable during operation as a spring in the gas piston assembly is being compressed and extended through the range of motion of the support structure to which it is attached; and
an actuation handle coupled to the proximal end of the support structure and connected to the proximal locking swivel joint, wherein rotation of the actuation handle acting about an axis generally aligned with a distal end of the support structure results in release of the proximal locking swivel joint thereby allowing repositioning of the support structure relative to the surgical table, wherein said non-linear support structure provides a single non-linear actuation path extending between said actuation handle and said proximal locking swivel joint such that said actuation handle is capable of actuating said locking swivel joint via said single non-linear actuation path to rotate said non-linear support structure about a lithotomy axis and an abduction/adduction axis.
