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.

A tattoo needle includes: a needle piercing portion. The needle piercing portion includes at least one piercing projection, wherein each of the at least one piercing projection comprises at least one substrate and a plurality of needle teeth. The number of the at least one substrate is one, the plurality of needle teeth is arranged on a side surface of the one substrate, the plurality of needle teeth are arranged in a row on the substrate, a central axis of each of the plurality of needle teeth is perpendicular to the side surface of the one substrate; and the one substrate is configured to limit a piercing depth that the plurality of needle teeth pierces into a skin.

An introduction needle includes a needle piercing portion. The needle piercing portion comprises a piercing projection, the piercing projection includes a substrate and a needle tooth, the needle tooth is fixedly arranged on a side surface of a side of the substrate, a central axis of the needle tooth is perpendicular to the side surface of the substrate.

A unit for supplying ink to the needles of a tattooing device includes a handling unit, in which the following can be found: a grip; a removable tip provided at one end with one or more tattooing needles; a coupling element configured to connect the grip and the tip to each other; a driver operatively associated with the grip to move the needles by imparting a reciprocating rectilinear motion to them; one or more tanks for containing the ink, operatively associated with the handling unit. The ink supply unit includes an air movement unit driven by the driver and mechanically connected to the handling unit. The air movement unit is configured to push the air moved by the driver toward the tank, the tank for containing the ink communicating with the air movement unit by a valve. Once conveyed into the tank by the valve, the air forces the ink to be dispensed from the tank onto the needles.

The method for automatically producing precise tattoo markings on any anatomical body portion automatically by providing a controlled articulated arm carrying a tattoo machine implement. The method also provides a multi-axis positioning platform for supporting and positioning a person, receiving a tattoo, in a prime, optimal, and comfortable position. Also, the method provides choosing, with a selector, a tattoo of choice from any data source of images, as well as applying, rectifying, and mapping, with a physical or virtual design projection and visualization media, the chosen tattoo to the person. The method completes a tattoo using the articulated arm with the tattoo machine implement producing a precise, accurate, and aesthetically pleasing tattoo, automatically.

A needle assembly for a liquid applicator comprises housing with longitudinal channel. The channel comprises upper and lower open ends. A needle bundle is movably mounted in the channel, which comprises needle shaft and needles attached thereto. A biasing member is configured and mounted for (i) biasing the needle bundle longitudinally towards a retracted position and (ii) biasing the needles laterally towards a needle-guiding side wall of the housing adjacent the lower open end. The biasing member is configured and mounted to form a fluid seal between the lower and upper open ends. The biasing member comprises an elastic tubular section with opposite sides. The first side has a first rectified length. The second side has a second rectified length longer than the first rectified length so that the second side is less tensioned than the first side to bias the needles towards the needle-guiding side wall.

An adapter for use with a tattoo machine is disclosed. The adapter may enable a tattoo machine configured with a wireless battery pack to switch to a wired configuration by removing the wireless battery pack and replacing it with the adapter. One end of the adapter may be affixed to a portion of the tattoo machine so that the adapter may deliver power to the componentry of the tattoo machine to facilitate the operation of the tattoo machine. The other end of the adapter may include a connector for enabling connection of the adapter to a power supply or power source so that power may be delivered from the power supply or power source through the adapter and to the tattoo machine. When the tattoo machine is powered, the motor of the tattoo machine may reciprocate a needle included in a needle cartridge affixed to the tattoo machine.

An arm-mounted motorized tattooing instrument includes a skin-perforating ink delivery wand configured for hand-held operation by a human operator, a wrist-or-forearm-mountable power supply, and a means for electrically coupling the skin-perforating ink delivery wand to the power supply. The instrument is configured to allow the human operator to operate the ink delivery wand without loss of power when rotating the ink delivery wand by hand about any of three orthogonal axes with the power supply mounted to a wrist or forearm of the same hand.

Provided herein are devices and methods used to produce tattoo biosensors that are based on spatially controlled intracutaneous gene delivery of optical reporters driven by specific transcription factor pathways for a given cytokine or other analyte. The biosensors can be specific to a given analyte, or more generically represent the convergence of several cytokines into commonly shared intracellular transcription factor pathways. These biosensors can be delivered as an array in order to monitor multiple cytokines. Biosensor redeployment can enable chronic monitoring from months to years. The tattooed biosensor array of the present invention includes endogenous reporter cells, naturally tuned to each patient's own biology and can be used to reliably measure the state of a patient in real-time.

A tattoo needle tip (10) with a capillary ink reservoir (13) and combined device thereof are provided. The tattoo needle tip (10) includes a needle tip body (11). A needle passage (100) is defined inside the needle tip body (11) for placing a tattoo needle (20). The needle opening (12) is communicated with the needle passage (100). A capillary disposed ink reservoir (13) directly connected to the needle opening (12) whereby can directly feed ink to the sharp end of the tattoo needle (20).
