  • Patent number: 5139503
    Abstract: A pair of obstetrical spatulas especially useful during the second stage or expulsion stage of labor during childbirth to assist in helping the fetal head to exit from the pelvic outlet by closely simulating the normal movements of the fetal head in the birth canal. Each spatula includes a blade provided with cephalic curve configuration to conform with and engage the fetal head with the blades including a shank or pedicule which form an angle of approximately 35.degree. with the longitudinal axis of the blades to provide a perineal curve. The pedicules are connected to a semicircular segment by a hinge at each end of the semicircular segment to enable articulate movement of the pedicules and blades in directions toward and away from each other and in longitudinal or axial directions.
