The days when surgery resembled the skinning of cattle are over. 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 by way of a cannula – which is a hollow tube that’s inserted through a tiny incision.
There are two primary ways that fat can be loosened or liquefied before removal –
With a liquefying fluid solution. This is actually 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, arteries and the sensitive dermis.
After the fat has been sufficiently liquefied, a cannula is inserted to eliminate the solution of fat cells and injected liquid. If simplyrenting of liquefying fat has involved a cannula, this is exchanged for a fresh 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 complete procedure less uncomfortable.
Twin cannulae. A twin cannula is a “tube within a tube”. As 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. Because of this 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 website of surgery is quite low indeed.
