Abstract
An actuator mechanism and assembly for sequentially advancing and retracting a lancet needle includes a housing having an opening for operating projection of the needle. Two guide tracks are provided within the housing for guiding separate motions of a two-part needle holder structure propelled by a drive spring, and the needle itself is smoothly guided along one of the tracks to advance and thrust the needle into a tissue penetration position immediately followed by automatic retraction along the same highly accurate linear path.
