I think that there are many ways to perform a Bbl and each doctor uses his own techniques to get the results he does. I always say it is the magician ( the surgeon) and not the wand( the instruments or machines) that creates the magic!
This is an interesting question. Many different types of surgical instruments can be used successfully to accomplish a BBL. The most important instrument is the surgeon and his experience with this procedure. In my practice for example, I have developed special instruments that make the trauma to the fat, while harvesting it, less traumatic. I have also developed and technique called Ultrasound-Image Guided Fat Augmentation Technique (UIGFAT) to more accurately place the fat and decrease the risk of injecting fat into a blood vessel. I have also developed instruments that allow me to mix the fat better into your body and I'm able to get about 50% more fat than I as able to before developing this instrument!
