Abstract: A radio-frequency apparatus is provided for vaginal tightening. The apparatus includes a main engine, a connection device, an applicator, and a negative plate, wherein the applicator includes a hand-held component and a treatment plug. The treatment plug has multiple RF electrodes distributed thereon, and has a size similar to the target tissue such that no movement is necessary during treatment. A controller is employed to connect a RF electrode driving circuit, trigger an electrode driving circuit conduction at a preset frequency as an output RF excitation source. Uneven RF current electrode treatment distribution can thus be resolved by using the RF electrode driving circuit to drive the conduction between the RF electrode and the RF source, at the same time by adopting multiple sets of RF electrode conduction for RF electrode configuration treatment, to ensure uniform distribution between each group of RF electrode currents.

Abstract: A radio frequency (RF) treatment apparatus includes a main machine and a treatment handpiece. The treatment handpiece may comprise an RF output device, comprising a controller, an RF electrode module, an RF electrode driving circuit, and an RF generation module. The treatment handpiece may also employ a modified arrangement of the plurality of RF electrodes and/or an adjusted series-connection pattern. The treatment handpiece may also be provided with a microneedle member, which includes a plurality of microneedles, a printed circuit board (PCB), and a substrate plate, wherein the plurality of microneedles comprise a plurality of long microneedles and a plurality of short microneedles.
