An 18G 100mm cannula is a medical device, typically a blunt-tip microcannula, used in aesthetic procedures such as dermal filler injections and body contouring. The 18-gauge refers to its large diameter, while the 100mm indicates its length (approximately 4 inches).

Product Details and Specifications

These cannulas are primarily designed for aesthetic applications, offering features that minimize patient discomfort and trauma to tissues. 

Tip Design: Most 18G 100mm cannulas for aesthetic use feature a blunt tip and a side hole to prevent piercing blood vessels and nerves, allowing them to glide under the skin.

Material: They are generally made from high-quality, flexible medical-grade stainless steel with a siliconized coating for smooth insertion.

Compatibility: They typically have a universal Luer-lock hub for secure connection to all standard syringes.

Sterility: They are sterile, individually packaged, and intended for single use to ensure safety and prevent cross-contamination.

Inclusion: Most packs for aesthetic use include a sharp pilot needle (introducer) of a slightly larger gauge to create the initial entry point for the blunt cannula.

Common Uses

The 18G 100mm size is specifically suited for high-volume or extensive area treatments due to its length and large bore: 

High-volume dermal fillers: Ideal for injecting more viscous fillers like hyaluronic acid or calcium hydroxylapatite.

Body contouring: Used in conjunction with body contouring dermal fillers.

Deep facial revolumizing: Applied for areas such as cheeks, jawline, and temples where an extended reach is needed.
