This obstetrical wax model shows forceps being used to disengage the head of a fetus in cephalic presentation. This is a "low forceps" application, to disengage the head from the inferior strait.

The model was commissioned by Felice Fontana, who was working on the installation of the Museo di Fisica e Storia Naturale of Florence, from the sculptor Giuseppe Ferrini and his assistant Clemente Susini.
