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 conducted by turning the fat into liquid form by some method, and removing the liquefied fat cells by way of a cannula – that is a hollow tube that’s inserted through a tiny incision.

There are two primary ways in which fat could be loosened or liquefied before removal –

With a liquefying fluid solution. This can be the process found in wet liposuction, super-wet liposuction, and tumescent liposuction

With ultrasound. In this technique, an ultrasound-enabled cannula is inserted subcutaneously to liquefy fat cells, carefully avoiding nerve cells, blood vessels and the sensitive dermis.

After the fat has been sufficiently liquefied, a cannula is inserted to remove the solution of fat cells and injected liquid. If the procedure of liquefying fat has involved a cannula, this is exchanged for a brand new one during suction. The cannula may be of several types –

Suction-assisted. All cannulae used for fat removal are suction-assisted, plus 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. liposuction cannulas is really a “tube within a tube”. Because the inner tube, which does the specific suctioning, moves within the outer tube, the trauma round the incision is minimized.

Non-surgical liposuction is a procedure that gives all of the benefits of surgery, but with really small external incisions. Therefore pain and threat 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 quite low indeed.
