Release handle mechanisms for a spar of a limb holder

A limb holder comprising

• a mount adapted to couple to a platform in a fixed position,
• a spar extending in an outward direction away from the mount and adapted to support a patient's foot relative to the mount,
• a first actuator including a trigger coupled to the spar to move relative to the spar about a first axis in response to application of a first force to the trigger to cause the spar to be freed to move about a vertical axis relative to the mount, and
• a second actuator including a grip coupled to the spar to move relative to the spar and the first actuator about a second axis in response to application of a second force to the grip to cause the spar to be freed to move about a horizontal axis relative to the mount,
• wherein the second axis is substantially perpendicular to the first axis,
• wherein the first actuator further includes a connecting linkage coupled to the trigger to move therewith back and forth along the second axis and arranged to extend from the trigger toward the mount, and
• wherein the first actuator further includes a lever coupled to the connecting linkage to move therewith about a pivot axis which is generally parallel to the horizontal axis.

• wherein the second axis is substantially perpendicular to the first axis and
• further comprising a multi-axis joint including a vertical-position lock and a horizontal-position lock, the horizontal-position lock interconnects the spar and the vertical-position lock and is movable between a blocking position in which movement of the spar and the vertical-position lock is blocked and an unblocking position in which the spar and the vertical-position lock are freed to move together relative to the joint mount, and the vertical-position lock interconnects the spar and the horizontal-position lock and is movable between a locked position in which the spar is blocked from moving relative to the horizontal-position lock and the mount and an unlocked position in which the spar is freed to move relative to the horizontal-position lock and the mount, wherein the multi-axis joint further includes a support platform and the horizontal-position lock lies between and interconnects the mount and the support platform to cause the support platform to move relative to the mount, and wherein the horizontal-position lock includes a stationary disk coupled to the support platform in a fixed position relative to the support platform, a set of movable pins coupled to the support platform and biased to extend away from the support platform toward the mount, and a movable disk coupled to the mount to move relative to the mount, the stationary disk, and the set of movable pins when the horizontal-position lock is in the unblocking position.
