the liposuction operation belongs to one of the body sculpturing operations of plastic and cosmetic surgery, and its principle is that the excess fat of a certain position of human body is sucked out by means of negative pressure suction so as to attain the goal of quickly slimming local body. The common parts of the whole body for fat absorption include the face, the two chin, the neck, the shoulder and back, the four limbs, the hands and feet, the upper abdomen, the lower abdomen, the side waist, the upper buttocks, the reduction of the buttocks, the lifting of the buttocks, and the like.

Liposuction has become increasingly popular in large cities. In the early 90 s of the last century, liposuction gradually exploded; fat loss through liposuction has become a trivial undertaking, and as with double-edged eyelid and nose augmentation, it has become one of the most common cosmetic and plastic programs. There are many methods for liposuction, such as electric method, syringe method, ultrasonic method, resonance liposuction, Korean layering liposuction and skin firming method, and electronic liposuction.

The conventional liposuction surgery is a liposuction surgery, and is performed in such a manner that a small hole is cut in a surgical site, a liposuction needle is inserted into a fat layer, and then the fat is sucked out by using the negative pressure of a liposuction machine. Because the diameter of the needle tube of the liposuction needle is 2.5mm, and the fat layer is thick and solid and is not easy to suck out, the traditional operation using the liposuction needle needs a doctor to hold the liposuction needle to pump the liposuction needle back and forth at the operation position.
