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. One of the hinge connections between the pedicule and semicircular segment is separable to enable more effective and accurate positioning of the blades in relation to the fetal head and pelvic outlet by individually positioning the blades after which the hinge is connected. A traction bar and handle with a force indicator is connected to the semicircular segment to control and indicate the traction force exerted on the spatulas.
An apparatus for assisting in the delivery of a baby during the second stage or expulsion stage of labor comprising a pair of spatulas, a connecting member hingedly connected to and extending between one end of the spatulas to enable the spatulas to be positioned in generally coextensive diverging relation from the connecting member when in use, a traction assembly attached centrally to the connecting member and including handle means connected to the connecting member to enable the connecting member to be pivoted to an angular position to orient one spatula generally longitudinally adjusted in relation to the other spatula to facilitate exit of the fetal head from the pelvic outlet of a mother and to correct asinclitic positions of the fetal head during birth.
Obstetrical spatulas comprising a pair of spatulas in the form of elongated members having a curved blade at one end, a connecting member extending between and hingedly connected to the other end of the spatulas, a traction bar assembly connected to the connecting member intermediate the hinge connections between the connecting member and spatulas, each spatula including an elongated shank extending from the blade to the connecting member, said blade on each spatula being curved downwardly from the shank to define a perineal curve with the entire blade being disposed below a horizontal plane along the upper edge of the shank.
