Abstract: A hand-held device for piercing a human or animal skin, comprises a housing, a drive device, which is arranged in the housing and is suitable for repeatedly providing a feed motion. The device also comprises a piercing device, which is formed in the housing with a needle and is coupled directly or, via a coupling device, indirectly to the drive device in such a way that the feed motion provided by the drive device can be introduced onto the piercing device. There is a housing opening, relative to which the needle moves forwards and backwards during operation, and a piercing depth adjuster, which is coupled to the piercing device in such a way that the piercing depth adjuster is displaceable relative to the tip of the needle and is entrained with the needle as the needle moves forwards/backwards during operation.

Abstract: The application concerns a handheld device for repeated local piercing of a human or animal skin, with a housing, a drive device, a conversion mechanism, and a piercing device, wherein the conversion mechanism has a crank pin (24) that is functionally connected with the drive shaft (21), wherein the crank pin (24) is coupled with a coupling component (25) that can be displaced back and forth transverse to the axial direction of the drive shaft (21), and is connected with the needle reception unit, such that the movement of the crank pin (24) is converted into a forwards and backwards movement of the coupling component (25), and thus of the needle reception unit, transverse to the axial direction of the drive shaft (21). The application furthermore concerns a drive module for a handheld device, together with a method for the operation of a handheld device.

Abstract: The invention relates to a handheld device for the local puncturing of a human or an animal skin, in particular for the introduction of an active substance or for the application of a tattoo or a permanent make-up, comprising a drive unit which is configured so as to produce a repetitive drive movement, and a needle unit which comprises a needle device and is configured so as to couple to the drive unit in such a manner that the repetitive drive movement for the extension and retraction of the needle device can be coupled into the latter, said drive unit having formed on it a displaceable actuating element which is functionally coupled to a needle connection device, and said needle unit having formed on it a functional member which is assigned to the actuating element, said actuating element and said functional member being configured so as to move the actuating element from a first displacement position to a second displacement position by means of the assigned functional member when coupling the needle unit
