Abstract: Disclosed are a treatment tip, a treatment handle and a treatment device. The treatment tip includes a shell, provided with a treatment surface configured to contact a treatment area; a negative pressure assembly, a transmission assembly, a drug delivery assembly and a needle board assembly. An outlet of the negative pressure assembly is opened on the treatment surface, and is configured to apply negative pressure to the treatment area. An end of the needle board assembly is communicated with an outlet of the drug delivery assembly, and at least one hollow needle is fixed on an opposite end of the needle board assembly. The at least one hollow needle is passed through the treatment surface while the at least one hollow needle is driven by the transmission assembly. An end of the drug delivery assembly is communicated with the needle board assembly.

Abstract: Disclosed are a treatment tip, a hand tool and a high-frequency skin treatment device. A treatment tip includes a needle plate portion having a plurality of needles; an adapter board portion, fixed inside the treatment tip; and a first flexible printed circuit, mechanically and electrically coupled between the needle plate portion and the adapter board portion; in relation to the adapter board portion, the needle plate portion is driven to move forth at a first position and move back at a second position; and the plurality of needles are partitioned and controlled such that the radio frequency signal from the handpiece is transmitted sequentially through the adapter board portion, the first flexible printed circuit and the needle plate portion to the partitioned plurality of the needles that radiate the RF signal to different zones of the skin.
