Coleman Injector Cannula – Luer Lock

Liposuction Cannulas and Accessories › Coleman Injector Cannulas › Coleman Injector Cannula – Luer Lock

The Coleman Injector Cannula with Luer Lock fitting is used to place fat in fat transfer and fat grafting. It is listed under Coleman Injector Cannulas, part of the Healermed Liposuction Cannulas and Accessories range.

Coleman Injector Cannula — Luer Lock

The Luer lock is the standard connection for fat injection. A threaded collar screws onto the syringe so the joint holds while the surgeon presses the plunger. On an injector that matters more than on an aspiration cannula: injection pressure pushes outward at the hub, and a slip fit can separate mid-pass and lose both the graft and the plane.

What Makes a Coleman Injector

The Coleman injector is the reference instrument for structural fat grafting, and surgeons ask for it by that name. It is a blunt-tipped injector with a single opening near the tip, made in fine diameters and short working lengths, and paired with a small syringe.

Everything about it serves one idea: fat survives when it is placed in small amounts, spread through the recipient tissue rather than pooled in it. A graft laid down as many fine threads has more contact with living tissue around it than the same volume deposited as a bolus, which is the whole basis of structural grafting technique.

The instrument enforces that. A fine cannula with one small opening cannot deposit quickly even if the surgeon presses hard, so the graft comes out as a controlled thread on each withdrawal. The blunt closed tip lets the cannula be passed repeatedly through the same site to cross and layer those threads without dividing vessels or nerves.

Short working lengths keep the tip close to the hand, which is what gives the tactile feedback a facial graft depends on. It is a precision instrument, and it is deliberately slow.

How an Injector Cannula Places Fat

An injector cannula is the delivery end of a fat transfer. The syringe supplies the pressure, but where the graft ends up, and in what form, is decided by the cannula: its diameter, its opening, and the way the surgeon moves it.

Placement is done in retrograde. The cannula is advanced through the recipient plane, and fat is laid down as it is withdrawn, so the graft fills the tunnel the cannula has just made rather than being forced into tissue ahead of it. Each pass deposits a thread of fat. A result is built from many of those threads, crossed and layered, not from a few large boluses.

That is why the opening matters. Its size sets the diameter of the thread laid down; its position sets which way the fat is directed as the cannula withdraws; and its edge decides whether the parcel passes cleanly or is sheared at the exit. A wider opening places more per pass and fills faster; a smaller one places less and gives finer control in thin tissue where the graft can be seen through the skin.

Diameter and length work with it. A narrower cannula makes a smaller tunnel and allows finer layering, but it also raises injection pressure for the same fat, so the surgeon pushes harder. A longer shaft covers more of the recipient area from one entry point, which means fewer punctures. Matching all of this to the graft volume and the recipient site is the whole skill of the instrument choice.

Specifications

Clinical Applications

• Structural fat grafting of the face
• Periorbital, temple, cheek and lip grafting
• Layered placement built from many fine threads
• Fine work with the 1.0mm to 1.8mm diameters

Material and Sterilization

The cannula is made from German stainless steel with a passivated surface that resists corrosion and pitting through repeated cleaning cycles. It is reusable and can be steam autoclaved at 134°C. Flush the lumen and the opening with clean water immediately after use and dry fully before autoclaving. Fine lumens block easily and are hard to inspect, so flush immediately after use before graft residue sets, and continue until the water runs clear. Check the opening under magnification, since a small deformity has a large effect at this diameter.

Why Buy Direct From the Manufacturer

Manufactured by Healermed Instruments, a surgical instruments manufacturer and exporter based in Sialkot, Pakistan. Factory-direct pricing removes the importer and distributor layer. Production runs under an ISO 13485 and FDA CGMP quality system, with ISO 9001 and CE Mark certification. OEM manufacturing and custom branding are available for distributor and brand-owner orders.

Frequently Asked Questions

What is a coleman injector cannula used for?

It is used to place fat in structural fat grafting, particularly of the face. A single small opening near the blunt tip lays the graft as a controlled thread on each withdrawal, so the fat is distributed through the recipient tissue in many fine layers rather than deposited as a bolus.

What makes a Coleman cannula different from other fat injectors?

Fine diameter, one small opening near a blunt tip, and short working lengths. The combination makes fast deposition physically difficult, so graft is placed as fine threads spread through the tissue rather than pooled. That is the basis of structural fat grafting rather than a limitation of the instrument.

Is this cannula autoclavable?

Yes. The instrument is fully reusable and can be steam autoclaved at 134°C. Flush the lumen and opening with clean water immediately after use, before graft residue sets, and dry completely before sterilization.

Which fitting should I order?

All four fittings are Luer lock types. Standard Luer lock suits most grafting syringes; stainless steel Luer lock is for high sterilization throughput; Super Luer Lock has a larger bore for lower injection resistance; universal Luer lock seats across syringe brands where consumable stock varies.

What is the minimum order quantity for bulk orders?

The minimum order quantity is agreed per order rather than set at a fixed number. Send us the sizes, fittings and quantities you need through the wholesale request page and we will confirm the minimum for that specification.

Do you provide samples?

Yes. Samples are available on request and the buyer covers the shipping charges. Tell us the diameter and length you want to evaluate and we will confirm what can be sent. Testing a sample first is the fastest way to check hub fit against the syringes you inject with.

Can I order a custom size?

Yes. Custom diameters, working lengths and opening configurations are available on request in addition to the standard size grid. Send your specification through the wholesale request page and our production team will confirm what can be produced.
