Tattoo machines configured to drive a needle towards a marking area. The tattoo machines include a motor, a first arm, a second arm, and a primary spring. The first arm is operatively connected to the motor and driven by the motor towards the marking area. The second arm is spaced from the first arm and configured to couple to the needle. The primary spring is biased to move the first arm and the second arm away from the marking area. The second arm is driven towards the marking area when the first arm is driven towards the marking area by the motor.

A kit to facilitate creation of and compliance with a personalized injection site rotation plan includes a plurality of disposable injection devices adapted for giving an injection of a medication to a patient in need thereof, each disposable injection device having a permanent, distinctive mark that may be the same as or different from the distinctive mark on other disposable injection devices in the kit; and a plurality of user-defined association tools, wherein for each unique distinctive mark on a disposable injection device, at least one user-defined association tool has a distinctive mark that corresponds to the unique distinctive mark.

Art Non-Fungible Tokens (NFTs) are typically associated with the ownership of the digital art. NFTs can be used in the field of tattooing to manage a tattoo client, art generation, art conversion into tattoo instructions, manage payment of stakeholders, allow a client to buy and sell tattoos in a secondary market, book/manage tattoo sessions, or combinations thereof. An NFT structure allows for the certification of ownership. For the context of tattooing, a smart contract may be used to track ownership of the digital design rendition of the tattoo and tattooing information. The NFT smart contract may contain the rights for the execution of the tattoo, which may allow one or many applications of a tattoo rendition of the NFT digital design, such right being consumed in the process of successive executions until the NFT may not contain any rights associated with tattooing.

This invention privilege patent belongs to the field of medicine and surgical instruments, and is intended to provide a new route of drug administration through needles plated with specific metals, aiming at better drug distribution and absorption upon administration, more precisely in the eyeball and/or on the patient's skin; to which the product has been originally improved in order to increase its efficacy in relation to other means of drug delivery known in the medical field, especially in skin, mucous and ocular diseases; it is an improvement that allows drug delivery to the skin and/or subcutaneous tissue, by means of a duly modified tattoo machine, which instead of ink, uses drugs, as a product to be inserted in the skin; in addition, this invention can be used to administer drugs directly to a person's eyeball, offering great practicality and agility to surgical procedures.

A tattoo machine apparatus is disclosed. The apparatus comprises a grip adjuster, a grip guide, and a ratchet disc. The components are arranged so that the grip adjuster houses a cartridge receiver and allows for needle depth adjustment while the grip guide ensures that the needle cartridge maintains its orientation and accepts the ratchet disc which provides positive stop adjustment and prevents unwanted rotation and thus accidental adjustment of the needle depth. In use, a backstem portion of a tattoo machine grip is inserted into the receiving portion of a tattoo machine. The tattoo machine is tightened down onto the backstem of the tattoo machine grip and holds it in place.

The invention relates to a drive device for a hand-held device (1) for locally puncturing a skin, having a housing (5) which is connectable to a module housing (8) of a skin-puncturing device; and an electrical drive device which is arranged in the housing (5) and has a tapping component which is designed to provide a tap for tapping a rotary drive movement generated by the electric drive device for the skin-puncturing device. The electric drive device has an electric motor designed as an external rotor with a rotating rotor component, in which the tapping component is arranged on the rotor component and eccentrically in relation to a rotor axis. Furthermore, a hand-held device (1) for locally puncturing a skin is provided.

Disclosed in the present invention is a motor comprising a coil assembly configured to produce a magnetic field in the axis direction of the motor when there is current in the coil, a line motion shaft set passing through the coil assembly in said axis direction, at least one end of said line motion shaft being set extending out of the coil assembly; and a permanent magnet set on the end of said line motion shaft extending out of the coil assembly; wherein when the coil assembly is supplied with current the direction of which alternates, the direction of the magnetic field produced in the axis direction of the motor alternates correspondingly, thereby producing attractive force and repulsive force on the permanent magnet alternatively.

A device for cosmetic treatment, in particular for permanent make-up, micro-needling or micro-pricking treatments, including a body having a first section, arranged at a first end of the body, in which a drive motor of the device (1) is arranged, a second section, arranged at a second end of the body, opposite the first end, in which a needle-holding cartridge can be fitted, and a third section, that connects the first section to the second section, in which drive means is housed of the needles contained in said needle-holding cartridge. The needle-holding cartridge includes a support element configured for supporting a single needle, or a plurality of needles and is movable inside a casing. of the cartridge The needle-holding cartridge is driven to move inside the casing by the drive means between a variable start position and a variable end position for a preset distance.

The present invention provides three embodiments to create and apply a tattoo to a dermal area of a recipient wherein the tattoo is non-permanent. The present invention includes a first embodiment and a second embodiment wherein the tattoo ink is removable via introduction of a solution and/or a solvent. A third embodiment of the present invention provides a method for tattoo ink creation that provides a tattoo ink that will degrade within the aqueous bodily environment over a period of time based on the polymer with which the water soluble dye is created. The first embodiment utilizes an organic dye that contains at least one metal atom. A solution containing a chelating agent is presented to the tattooed area wherein the chelating agent will extract the metal atom resulting in disappearance of the tattoo ink. Another embodiment utilizes wax encapsulated ink to be removed by presentation of a solvent.

A transparent tattoo stencil transfer and associated method are provided herein. The transparent tattoo stencil transfer allows a tattoo artist to transfer a selected design onto a transparent plastic sheet for accurate and precise placement of the design from the transparent plastic sheet onto a client's skin. The transparent tattoo stencil transfer may comprise at least a backing sheet, a polyester carbon sheet positioned on top of the backing sheet, a plastic sheet positioned on top of the polyester carbon sheet, and a semi-transparent tissue sheet positioned on top of the plastic sheet. A tattoo design may be placed between the backing sheet and the polyester carbon sheet. A heat transfer process is performed using a thermofax machine to transfer a carbon image of the tattoo design onto the plastic sheet using the polyester carbon sheet.
