Using traditional mechanisms of liposuction such as SAL requires the surgeon to manually move the cannula through the parts of the body where fat is being removed. The cannula must be moved back and forth through the tissue, which can sometimes be difficult and tiring. It can also prevent the surgeon from removing all of the fat necessary for the procedure to be efficient and successful. Power-assisted liposuction involves the uses of a specialized mechanical device added to the cannula to help in the removal of fat. The device not only helps in the removal of fat, but it allows for the surgeon to be more precise in the removal.
The device used in power-assisted liposuction is a specialized cannula, which is the hollow wand used to extract the fat from the body. This special cannula incorporates a mechanical device on the tip that creates small but rapid vibrations. These vibrations break up fat cells so they can be removed more easily through the cannula. This action that breakups the fat allows the surgeon to remove fat more efficiently and in less time than with a traditional cannula. The shorter period of time makes the procedure safer because there is less chance of infection. The procedure also has a faster recovery time than longer, older forms of liposuction. The vibrating tip also allows the surgeon to guide the cannula through the tissue with less effort, and the movement allows for greater precision. Specific areas can be precisely targeted without causing damage to other surrounding tissue.
The mechanism of power-assisted liposuction is performed in conjunction with the tumescent liposuction technique. Tumescent liposuction involves the injection of a high quantity of solution before the actual suctioning takes place. This solution is a mixture of a local anesthetic and a vasoconstrictor. The local anesthetic is often lidocaine and helps to reduce pain. A common vasoconstrictor is epinephrine, which minimizes bleeding during the surgery. The solution is injected directly into the fat tissue.
Power-assisted liposuction has several benefits over other older and more traditional forms of liposuction. Even though a vibrating tip seems like a simple addition to a liposuction cannula, its benefits are invaluable. Some the benefits include the following:
