Abstract: Objective To discuss the microstructure and properties of vascular puncture with a blunt needle Pix'L filling injection.Methods Scanning electron microscopy (SEM) and photoelectron spectroscopy were employed for the analysis of the different morphology and elements,and a rat model was established to study thrusts of different microcannulas and hypodermic needle when stabing vessels.Ultimately we analyzed the correlation between the morphology and puncture force of different microcannulas.Results The SEM images of microcannulas from different manufacturers were different,and revealed the different technics of different manufacturers.Puncture forces of different microcannulas corresponded to the cross-section and smooth degree of the tips.Conclusions The SEM morphology and puncture force of microcannulas from different manufacturers are different,which indicate the different characters and usability.Plastic surgeons should select to use them more judiciously.
