1. A limb holder comprising:
a mounting bracket for attachment to a surgical table;
a mounting element comprising a semi-spherical surface and a neck connecting said semi-spherical surface to said mounting bracket;
a clamping assembly for providing a clamping engagement about said semi-spherical surface of said mounting element, said clamping assembly comprising:
an upper jaw comprising a bottom surface and a concave gripping surface and a lower jaw comprising a top surface and a concave gripping surface;
a first bore opening into said upper jaw from said bottom surface of said upper jaw and a second bore opening into said lower jaw from said top surface of said lower jaw;
a spring element disposed in said first bore of said upper jaw and said second bore of said lower jaw, said spring element being configured to bias said upper jaw towards said lower jaw so as to provide said clamping engagement about said semi-spherical surface of said mounting element by engagement of said concave gripping surface of said upper jaw and said concave gripping surface of said lower jaw about said semi-spherical surface of said mounting element;
an upper protrusion and a lower protrusion extending along said neck of said mounting element, said upper protrusion and said lower protrusion being configured to cooperate with an upper limit surface on said upper jaw and a lower limit surface on said lower jaw, whereby to limit movement of said upper and lower jaws about the semi-spherical surface of said mounting element;
a limb support element mounted to said clamping assembly via a support rod; and
a release mechanism mounted to said support rod and connected to said clamping assembly, said release mechanism being configured to selectively exert a force against said spring element, whereby to selectively release said clamping engagement of said clamping assembly about said semi-spherical surface of said mounting element, whereby to allow said limb support element to be repositioned relative to said mounting element and hence repositioned relative to the surgical table.
