[The inventors of the obstetric forceps and the obstetric lever].

A multiple lineage is proposed for the invention of the obstetric forceps. Having been conceived by a member of the Chamberlen family in fifteenth- or seventeenth-century England, the instrument seems to have been reinvented in Flanders by Jan Palfyn and in Holland by Rogier Roonhuyse. Later, Roonhuyse invented a more effective instrument for coping with the impacted head: the obstetric lever. Palfyn's "Iron Hands" inspired Dussé to produce the "French" forceps which bears his name.
