Cannulas

What This Collection Covers

• Liposuction cannulas — single-hole, two- and three-hole, diagonal three-hole, eight- and ten-hole infiltration designs; half-cut and top-hole tips; 1.7mm to 6mm diameters, 5cm to 35cm long; Luer-lock or handle connection
• Infiltration cannulas — 10-hole, 2mm x 25cm and 3mm x 35cm
• Kotzur liposuction cannula and a Luer-lock handle adapter
• Ophthalmic cannulas — McIntyre anterior chamber cannulas (23–30G, straight and angled), Heslin infusion cannulas (23G, 25G), lacrimal cannulas, LASIK irrigation cannulas (single and double arm, 25G)
• ENT cannulas — Killian antrum cannulas, laryngeal and laryngeal suction cannulas with Luer-lock
• Other — bayonet injection cannula, 22G infusion cannula

Why the Hole Pattern Matters

In liposuction the holes near the tip decide how fat is drawn in. A single central hole is the most controlled and is used for delicate or finishing work. Multiple lateral holes pull from a wider area and remove volume faster. Small-diameter, many-holed infiltration cannulas spread tumescent fluid evenly before aspiration starts.

So surgeons usually work with a range: infiltration first, then larger multi-hole cannulas for debulking, then fine single- or three-hole cannulas for contouring. The listings are named by hole layout so you can build that sequence.

How to Choose

Diameter. Larger diameters (4–6mm) move volume; smaller ones (1.7–3mm) refine contour and suit face, neck and fat harvest for grafting.

Length. Short cannulas (5–15cm) for face and small areas; 30–35cm for abdomen, flanks and thighs.

Connection. Luer-lock cannulas attach to a syringe for small-volume and grafting work. Handle-connection cannulas fit an aspiration handle.

Ophthalmic gauge. Higher gauge means a finer cannula: 30G is finer than 23G. Angled tips reach under the iris and across the chamber.

Frequently Asked Questions

What is an anterior chamber cannula used for?
Irrigating the anterior chamber of the eye and injecting fluids or viscoelastic during cataract and other intraocular surgery.

What is an infiltration cannula?
A fine, multi-hole cannula used to spread tumescent fluid through the tissue before liposuction.

Can I use these with a syringe?
Luer-lock models connect directly to a syringe. Handle-connection models need a compatible handle, and an adapter is listed.
