FIELD: medicine.
SUBSTANCE: invention refers to medical neurosurgical instruments and may be used for performing resection craniotomy in small and medium experimental animals. Cutting jaws of the device are crescent-shaped along a rig of the same radius of curvature. The lower jaw has a sharp upper cutting edge. The upper jaw has a loop slot and a sharp internal lower cutting edge. Shape and size of the loop in the upper jaw matches those of the lower jaw for moving the lower jaw in the slot.
