cannula
Pronunciation: KAN-yoo-lah
Thin tube used in cosmetic procedures for injection or suction of materials.
Full Definition
A cannula is a thin, flexible or rigid tube used in various cosmetic procedures to deliver or remove materials from the body. In liposuction, cannulas are used to suction out fat deposits, while in fat transfer or dermal filler procedures, they serve to inject materials into target areas. Cannulas come in different sizes and configurations, with blunt-tip cannulas often preferred for safety when injecting near sensitive structures. The choice of cannula affects both procedure safety and aesthetic outcomes.
Usage
Usage note: Distinguish from needles, which have sharp tips, and catheters, which are typically longer-term devices.
