US Patent 10449346 Tattooing needle assembly

An improved tattooing needle assembly and support assembly for the needle assembly are provided. The needle assembly includes a needle component extending through a main case into an aperture assembly. The needle component is configured to reciprocate between a stowed configuration, in which a tip of the needle component is positioned within the aperture assembly, and a deployed configuration, in which the tip extends beyond the aperture assembly. A tattooing machine causes the needle component to move to the deployed configuration while opposed magnets bias the needle component back towards the stowed configuration. Using a needle protection sleeve, the needle assembly can be removed from and/or installed onto a tattooing machine without requiring a user to come into direct contact with the needle assembly. By securing the needle protection sleeve to a support assembly, the removal and/or installation of the needle assembly becomes a one-hand operation.
