Warning: traditional liposuction cannulas may be dangerous to your patient's health.

Liposuction is the most frequently performed invasive cosmetic procedure in the United States. The vast majority of liposuctions are performed using mechanical aspirators that are connected by sterile tubing to a cannula. Although liposuction cannula shaft designs have been modified and "perfected" to various extents, little attention has been paid to the handle and handle/shaft junction. Herein we present an inherent design-induced difficulty of traditional liposuction cannulas, the inability to be optimally cleaned. In addition, we present a solution.
