Liposuction cannulas used in aesthetic surgery for liposuction. Hereby the long needles are preferably used in the range abdomen and hip. The short and narrow liposuction cannulas are ideal for the facial area and the Leg and arm area. By connecting to a suction pump, a continuous suction is created which directs the fat-water tissue through the liposuction cannula and a tube into a container. The advantage of this liposuction method is particularly precise and tissue-friendly.
