ABSTRACT:
A device for locally puncturing skin is disclosed, especially for applying permanent make-up or a tattoo, comprising a housing, a needle guided in the housing for movement between extended and retracted positions, and a diaphragm made of an elastically extensible material and dividing a front-end space at a front surface of the diaphragm from a rear-end space at a back surface of the diaphragm in the housing. A coupling mechanism firmly couples the needle and the diaphragm for backward movement of the needle in the direction of the retracted position, a return force generated by the diaphragm for moving the needle back in the direction of the retracted position being introduced into the needle shaft.
