Abstract
|
|
|
|
Uniform mixing of liquid substances is difficult to attain. Recently, mixtures of fat and platelet-rich plasma (PRP) have been used extensively in autologous fat transfer. Although various methods have been utilized to mix the fat and PRP involved in this procedure, these methods still carry disadvantages in the time taken and the potential for cell damage, and it is questionable whether effective mixing can occur using these techniques. To facilitate mixing that is as uniform as possible, the authors of this study invented a special cannula. Use of the conventional luer-lock-to-luer-lock connector method has been found to cause cell damage and makes it difficult to achieve uniform mixing, while random injection-type mixing has been shown to have limited accuracy and effectiveness. We expect that the newly designed cannula will solve the problem detailed above.
