cannula
Hollow tube used in plastic surgery for fat removal, injection, or fluid drainage.
Full Definition
A cannula is a thin, hollow tube made of stainless steel or other medical-grade materials used in various plastic surgery procedures. In liposuction, cannulas range from 2-6mm in diameter and feature side holes for fat aspiration. They may be blunt-tipped for safety or sharp for initial tissue penetration. Different cannula designs serve specific purposes: microcannulas for delicate areas, basket cannulas for fibrous tissue, and specialized cannulas for fat grafting procedures. The choice of cannula affects surgical outcomes, patient comfort, and recovery time.
Usage
Usage note: Plural form is 'cannulas' or 'cannulae'; distinguish from catheter (for drainage) and trocar (for initial puncture).
