Description

Radio frequency fat sucking device Technical Field The utility model relates to the technical field of medical equipment, in particular to a radio frequency fat suction device. Background Liposuction is colloquially known as the extraction of fat. Liposuction is a method for improving obesity by connecting a negative pressure vacuum aspirator with a metal suction tube with a suction hole at the tail end, entering the skin through a small incision of the skin, and sucking out locally accumulated adipose tissues. In the related art, the rf liposuction device is generally designed as an inner electrode and an outer electrode, the inner electrode enters the inside of a human body and the outer electrode is fully contacted with the surface of the skin when in clinical use, the rf energy is output between the inner electrode and the outer electrode to generate heat, so that fat cells are destroyed, and meanwhile, collagen in the skin is elastically contracted due to heating, so that the effects of fat dissolution and shaping are achieved.
