Description
Technical Field

[0002] At present, energy source medical beauty (photoelectric medical beauty) can be said to be the mainstay of the entire medical beauty equipment. Energy source medical beauty refers to the application of energy forms such as laser, radio frequency, ultrasound and ion in medical beauty. Non-ablative fractional laser therapy is a minimally invasive laser technology that penetrates into the dermis to treat skin wrinkles or scars. This skin treatment head is installed on the handle of the non-ablative fractional laser therapy device to perform contact treatment on the skin. Skin treatment heads are divided into single metal frame type and optomechanical component type. This treatment head belongs to the optomechanical component type, which includes structural movement, integrated circuits, and optical lenses, and is used in non-ablative fractional laser therapy devices.
