Description

TECHNICAL FIELD

[0001] The present application relates to the field of focused ultrasound cosmetic technology, in particular to a rotating focused ultrasound hand tool, a negative pressure hand tool and a cryogenic radio frequency hand tool. BACKGROUND

[0002] Focused ultrasound knife is a cosmetic technology that has emerged this year. It is a special concave ultrasound sheet that focuses ultrasound energy into a very small point. The diameter of the point is only about one millimeter, but the heat generated is very large, which can directly cause thermal damage to the tissue, and the temperature can reach 65-70 DEG C. The operating depth of focused ultrasound is 1.5mm-4.5mm. The ultrasound energy produces thousands of very fine independent heat coagulation points, which can reach the fascia layer and stimulate the continuous regeneration of collagen, rebuild the elastic and powerful support network, and continuously lift and tighten the contour.

[0003] However, since the ultrasound energy is focused into a point, the diameter of the point is very small, and it takes a long time to complete the whole face cosmetic, which is not conducive to the operation and the popularization of the equipment. Therefore, a focused ultrasound hand tool capable of increasing the operation area and saving operation time is needed. SUMMARY

Preferably, in this embodiment, the cooling water temperature is greater than 6°C to improve the user experience.

[0111] Based on the aforementioned rotating focused ultrasound handpiece 35, by adding a handpiece head base 43 and a handpiece head 42, the handpiece head 42 is made of metal and connected to a radio frequency (RF) cable, thus adding RF functionality to the handpiece during operation. The thermal effect can improve the cosmetic results. At the same time, two water connectors 44 are provided at the rear end of the water storage shell 7 for introducing circulating chilled water into the water storage shell 7, thus adding a cooling function to the handpiece head 42 during operation, preventing the high heat of the focused ultrasound energy from burning the epidermis.
