Both the EndoVac Handpiece and fingerpiece are part of the EndoVac endodontic irrigation apical negative pressure system.The EndoVac MacroCannula, placed in the Single EndoVac Handpiece, pulls irrigant into the canal and evacuates gross debris. The MicroCannula, placed in the Single EndoVac Fingerpiece, draws the fluid to the apical termination through the holes of MicroCannula, creating a vortex-like cleaning of the apical third.
