Abstract: A concealable surgical light device, such as for a birthing room, has a fixed housing and a single door for supporting the light on one side and decorative ceiling panels on the other side. The door is rotatably attached to the fixed housing. In a closed position of the door, the light is concealed within the ceiling structure, and the decorative panels are flush with the ceiling. In an open position, the light is deployable as it faces into the room. Rotation of the door between the two positions is powered by a motor acting through an actuator and a linkage system. The linkage system includes two first arms rotatably connected to an actuator rod and fixed to a pivot shaft such that extension and retraction of the rod pivot the shaft. Two second arms are fixed to opposite ends of the shaft and pivotally connect to two third arms, in turn connected to the door. Pivoting the shaft rotates the second arms which, in turn, move the third arms up or down to close or open the door.

Abstract: A concealable surgical light device such as for a birthing room has a frame for supporting the light on one side and a decorative panel on the other side. The frame includes reinforcing ribs positioned in a Y shape, and a cylindrical section at the intersection of the ribs for attaching the light. The frame is rotatably supported inside a housing which is fixed within the ceiling structure. At one end of the housing there is a fixed tube and a bearing and at the other end is an output shaft of a speed reducer gear connected to the frame through a torque limiter and slip clutch for rotatably supporting the frame. Wires are fed through the tube without being subjected to rubbing or twisting. In a closed position of the frame, the light is concealed within the ceiling structure and the decorative panel is flush with the ceiling. In an open position, the light is deployable as it faces into the birthing room.

Abstract: A controlled motion ankle fracture walker includes a foot supporting rocker to which the foot of a patient is releasably secured, and a leg support wrapped around the patient's lower leg above the ankle joint. The foot support includes a rigid shell with a curved bottom forming a rocker for rolling contact with the ground to provide a rocking heel to toe motion of the patient's foot during weight bearing. Rigid lateral and medial uprights are rigidly affixed alongside the leg support, and adjustable double action ankle joints pivotly interconnect the bottoms of the uprights with the rigid support arms on the lateral and medial sides of the foot supporting shell. The ankle joints permit adjustable range of motion of the uprights in dorsiflexion or plantar flexion.
