Four drawers of the surgical instrument kit designed by Giovanni Alessandro Brambilla contain instruments for operations on the skull:
No. V, PRO FRACTURA CRANI—instruments for treating skull fractures (scrapers, knives, hooks, levers, tweezers, clamps, hammer);
No. VI, TRAPANUM—trepanation instruments;
No. XXX, SCALPELA ANOTOMICA—dissection instruments (cutters, saw, lever);
No. XXXI, PRO INIECTIONE—supplements no. XXX, with syringes and cannules for injecting fluids in the vessels of a corpse. The last two drawers thus comprise the anatomical instrumentation.
The instruments were made by the cutler Joseph Malliard.
