COLIN’S BISTOURY CACHÉ.
CHARLIER’S METHOD—INSTRUMENTS.
For this operation special instruments are required. These consist of, first, a vaginal dilator ([Fig. 29]), or speculum, of peculiar and somewhat complicated construction, to be modified subsequently by another ([Fig 30]), of superior form and easier of application, and now in general use; second, a bistoury caché ([Fig. 31]), sliding on its handles, which is a true embryotomy knife, modified by Colin ([Fig. 32]); third, a pair of long, sharp scissors ([Fig. 33]), with guarded blades, curved on its flat surface; fourth, a torsion forceps ([Fig. 34]), closed by a peculiar thread arrangement, moved by the handle; and fifth, a steel thimble ([Fig. 35]), which has been modified by the instrument shown in [Fig. 36], and which is used in applying the limited torsion on the broad ligaments.
