Embodiment Construction
[0051] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0052] The radio frequency microneedle therapeutic apparatus includes a power supply 100 , a microneedle array 200 , a switching circuit 300 , and a controller 400 .
[0053] Wherein, the output frequency of the power supply 100 may be 0.3MHz-100MHz, and the power supply 100 may be a continuous output power supply or a pulse output power supply or a common output power supply of both continuous and pulse outputs. The power supply 100 may only include one, that is, a single power supply 100 supplies power to all the microneedle arrays 200 . Alternatively, the power supply 100 may also include multiple power supplies 100 connected to the switching circuit 300 respectively. Any microneedle electrode in the microneedle array can be powered by any power supply 100 through a switch switching circuit. Alternatively, each r...

The present invention provides a radio frequency microneedle array control method and device, and a radio frequency microneedle therapeutic instrument. The control method of the present invention includes the following steps: obtaining coordinates corresponding to a plurality of microneedle electrodes; determining from the coordinates of a plurality of microneedle electrodes At least one set of target coordinates, wherein each set of target coordinates includes two target coordinates; a first control signal is sent to the switch switching circuit to control the switch switching circuit to set the target microneedles corresponding to at least one set of target coordinates within the first preset time period The electrodes are connected to the power supply, and the control switch switching circuit provides the first polarity for the target microneedle electrode corresponding to any one of the target microneedle electrodes corresponding to each group of target coordinates, and supplies the second electrode for the other. property; return to the step of determining at least one set of target coordinates from the coordinates corresponding to the plurality of microneedle electrodes. The radio frequency therapeutic apparatus adopting the method has multiple transformed energy output points during the radio frequency microneedle treatment process, which is beneficial to more uniform output.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a radio frequency microneedle array control method and device, and a radio frequency microneedle therapeutic instrument. Background technique [0002] Radio frequency microneedle therapy is a micro-invasive radio frequency fractional technology. It uses tiny micro-needles to precisely apply radio frequency (RF) energy to target tissues at different depths. It can be used for facial rejuvenation such as skin firming and scar removal. Application, can also be used for acne treatment, armpit hyperhidrosis treatment. [0003] However, there are still many problems in the current microneedle fractional radio frequency treatment process. For example, the microneedle electrodes are designed with fixed positive and negative electrodes, that is, the same microneedle electrode always acts as the positive electrode or always acts as the negative electrode during the application proc...
