摘要：
Embodiments of an actuating device for actuating a needle cartridge and puncturing an epidermis with controlled depth. The actuating device includes a motor housed in a motor housing, an actuating rod driven by the motor and configured to actuate in a reciprocating motion, and an adjustment mechanism. The actuating rod is housed in a rod housing, the rod housing forming a device aperture configured to receive a needle cartridge and to attach to the needle cartridge. The adjustment mechanism interfaces with the rod housing and is configured to adjust a position of the rod housing relative to the motor housing while not rotating the rod housing relative to the motor housing.
