Reconfigurable pelvic support for a surgical frame and method for use thereof

A positioning frame for supporting a patient during surgery including an adjustable pelvic support, the positioning frame comprising:

• a first vertical support portion and a second vertical support portion;
• a main beam having a first end, a second end, and a length extending between the first and second end, the main beam defining an axis of rotation relative to the first vertical support portion and the second vertical support portion, the main beam being rotatable about the axis of rotation between at least a first rotational position and a second rotational position, the axis of rotation substantially corresponding to a cranial-caudal axis of the patient when the patient is supported on the positioning frame, the main beam including a first portion at the first end rotatably interconnected relative to the first vertical support portion, a second portion at the second end rotatably interconnected relative the second vertical support portion, and an elongated portion extending between the first portion and the second portion of the main beam,
• a chest support portion and a leg support portion attached to the elongated portion of the main beam;
• and
• an adjustable pelvic support including a tilt positioner, a first arm portion, a second arm portion, a head portion, a first connecting linkage, and a second connecting linkage, the tilt positioner being attached to the main beam, the first arm portion including a first end portion and a second end portion, the second arm portion including a first end portion and a second end portion, the head portion including a pad portion for contacting a portion of the pelvic area of the patient,
• the first end portion of the first arm portion being pivotally attached to the tilt positioner,
• the first end portion of the second arm portion being pivotally attached to the second end portion of the first arm portion,
• the head portion being attached relative to the second end portion of the second arm portion,
• the first connecting linkage extending between a first portion of the tilt positioner and the second end portion of the first arm portion, the first connecting linkage being hingedly attached to the first portion of the tilt positioner and the second end portion of the first end portion,
• the second connecting linkage extending between a second portion of the tilt positioner and the first end portion of the second arm portion, the second connecting linkage being hingedly attached to the second portion of the tilt positioner and the first end portion of the second end portion,
• the tilt positioner being configured to tilt the first arm portion between a first tilt position away from the patient and a second tilt position toward the patient, and the first arm portion being moveable between a first rotational position and a second rotational position relative to the elongated portion of the main beam, and the second arm portion being moveable between a first rotational position and a second rotational position relative to the first arm portion to facilitate positioning and repositioning of the pad portion of head portion to contact the portion of the pelvic area of the patient during rotation of the main beam between the first rotational position and the second rotational position.
