obstetric forceps

obstetric forceps,

forceps used to assist delivery of the fetal head. They vary in weight, length, shape, and mechanism of action, but all consist of a pair of instruments comprising a handle, a shank, and a blade. The blade is curved and sometimes has openings. The shank is long enough to allow the blade to reach the fetal head. The several styles of forceps are designed to assist in various clinical situations. The station of the fetus in the pelvis, the position of the head in relation to the pelvis, the size of the fetus, and the preference of the operator all affect the choice of forceps. Kinds of obstetric forceps include Barton forceps, Elliot forceps, Kielland's forceps, and Simpson forceps. See also forceps delivery.
