The days when surgery resembled the skinning of cattle are long gone. Today, most surgery is conducted by keyhole methods, with the insertion of cannulae and the use of precision instruments.
Liposuction, here, is no exception. Today, liposuction is performed by turning the fat into liquid form by some method, and then removing the liquefied fat cells through a cannula – which is a hollow tube that is inserted through a tiny incision.
There are two primary ways in which fat can be loosened or liquefied before removal –
With a liquefying fluid solution. This is the process used in wet liposuction, super-wet liposuction, and tumescent liposuction
With ultrasound. In this process, an ultrasound-enabled cannula is inserted subcutaneously to liquefy fat cells, carefully avoiding nerve cells, blood vessels and the sensitive dermis.
Once the fat has been sufficiently liquefied, a cannula is inserted to remove the solution of fat cells and injected liquid. If the process of liquefying fat has involved a cannula, this will be exchanged for a fresh one during suction. The cannula may be of several types – microaire cannulas
Suction-assisted. All cannulae used for fat removal are suction-assisted, and they may have additional features to help them perform the function.
Power-assisted. Power-assisted cannulae are operated with electricity, so that they can make small and precise movements. This makes the entire procedure less uncomfortable.
Twin cannulae. A twin cannula is a “tube within a tube”. As the inner tube, which does the actual suctioning, moves within the outer tube, the trauma around the incision is minimized.
Non-surgical liposuction is a procedure that gives all the benefits of surgery, but with very small external incisions. This means that pain and risk of post-operative infection are minimized. Also by loosening the fat cells through non-invasive means before suctioning them out, trauma to the site of surgery is very low indeed.
