Vaser Liposuction

The resonance concept VASER® is based in two basic premises: The frequency of 36 kHz is next to the resonance of fat; and for that reason there is less energy transfer to other tissues. Furthermore, the adipose cells, much larger in size comparatively to other adjacent tissues (blood vessels, nerves, conjunctive tissue), are more susceptible to ultrasonic energy. In this concept the ultrasonic technology is produced by a conversion of electric energy in sonic vibration waves through a handpiece. Such vibration moves a titanium probe in a constant frequency of 36 kHz. The interaction between the probe design and the sound reverberation on the tissue determines the efficiency of the system .

The subcutaneous cellular tissue which is found in a humid environment receives the sonic energy emanated by this probe.

There are two functional mechanisms. The first and less frequent tears the cellular membrane by direct impact. The second principle is called cavitation, this phenomenon can be understood through the vibratory frequency of the sound wave that acts as an effect of compression and rarefaction, which are emitted by its distal rings. Microbubbles are formed in the tumescent liquid inside the adipose tissue. These evolve hundreds of adipocytes. The energy is gradually dispersed and the diameter of the microbubbles gradually increased until the moment of its rupture. In that exact instant, the adipocytes detach themselves, without damage to its architecture; nevertheless altering its physical density from solid to emulsified. The cavitation and the mechanical rupture of the adipose tissue is selective, that is, the diameter of the adipose cell is larger than the adjacent tissue micro-architecture (blood vessels, muscular fibers, connective tissues), so being that this environment remains intact. The equipment had enough power and precision to treat different body areas without the need to employ force to overcome zones of tissue resistance.

VASER® is composed by an integrated system, formed by a display (ultrasound), handpiece, probes (special astraumatic rod), suction tower system (ventilated aspiration system), integrated system of irrigation and triggering pedals. This complete equipment unites all the apparatus needed for the realization of the liposuction surgery in an organized manner, offering safety, comfort and practicality to the surgeon.

Not everyone is a good candidate for liposuction. It is not a good alternative to dieting or exercising. To be a good candidate, one must usually be over 18 and in good general health, have tried a diet and exercise regime, and have found that the last 10 or 15 pounds persist in certain pockets on the body. Diabetes, any infection, heart or circulation problems, generally nullify one’s eligibility for the procedure. In older people, the skin is usually less elastic, limiting the ability of the skin to readily tighten around the new shape. Liposuction of the abdominal fat should not be combined with simultaneous tummy tuck procedures due to higher risk of complications and mortality. In many parts of the world Laws prevent practitioners combining liposuction of the upper abdomen and simultaneous abdominoplasty because of higher risks.
