Obstetrical forceps for assisting in the delivery of a baby. The forceps include a pair of elongated members pivotably connected with each other. Each member includes a fetus-engaging blade portion and a handle portion. At least one of the members has means movably connecting the blade portion thereof to its handle portion. Such blade and handle portions are connected in such a manner that the blade is shiftable a limited amount with respect to the handle. Biasing means are provided for holding the shiftable blade in an axially aligned position with respect to the handle. The biasing means are constructed and arranged to impart a predetermined holding force on the blade for holding the respective shiftable blade and handle together whereby when a force above and generally opposite in direction to the holding force is applied to the shiftable blade, as during the use of the forceps to assist delivery of a baby, the shiftable blade portion will shift its position relative to the handle. |
