The twin action concept of the pneumatic Twinac Guillotine cutters uses air pressure for both, the push and the retract movement of the cutter, thereby eliminating the need for a mechanical reset spring. This allows excellent and indepemdemt control of the cutting and the aspiration cycle and speed control from single cuts uo to 3000 cuts/minute. The ergonomic design allows pencil type holding (extension sleeve attached) or finger tip holding (extension sleeve removed).
