Long Hole Injector Cannula – Stainless Steel Luer Lock

Liposuction Cannulas and Accessories › Long Hole Fat Aspiration Injector Cannulas › Long Hole Fat Aspiration Injector Cannula – Stainless Steel Luer Lock

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

Long Hole Fat Aspiration Injector Cannula — Stainless Steel Luer Lock

Hub material decides how long a reusable injector stays usable. Anodized aluminium hubs are lighter and cheaper, but the coating fades and the thread can gall after repeated steam cycles. A solid stainless steel hub keeps its thread form far longer, which matters on an instrument that is screwed on and off a syringe many times in a single grafting case.

What a Long Opening Does on an Injector

One opening, cut long along the shaft rather than as a compact hole. On an injector, length changes the shape of what is placed rather than simply the amount.

A compact opening lays a narrow thread of fat. A long opening lays a broader, flatter ribbon, because the graft leaves along the whole run of the aperture as the cannula withdraws rather than from a single point. Over a wide recipient area that fills more evenly and in fewer passes.

Because it works in both directions it also collects. The same long aperture aspirates fat efficiently, which is why the instrument carries the aspiration name: for moderate graft volumes it will harvest and place without an instrument change, on a cannula sized for both.

The trade is control. A long aperture places more per withdrawal than a small hole, so it fills a broad area well and is the wrong instrument for fine layering in thin tissue, where a single small opening gives the precision the site needs.

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 The cannula is advanced through the recipient plane, and fat is laid down as it is withdrawn, so the graft fills the tunnel the cannula has just made rather than being forced into tissue ahead of it.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.

Key Features

• ✔ Closed blunt tip separates the plane without cutting

Specifications

Clinical Applications

• Body fat grafting over wide recipient areas
• Moderate-volume transfers where one instrument harvests and places
• Gluteal and breast fat transfer with the larger diameters
• Cases where pass count limits the operating time

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. A long aperture holds more residue than a small opening, so flush from the hub until the water runs clear and run a light along the full length of the opening at each cycle to check for nicks or dulled sections.

Frequently Asked Questions

What is a long hole fat aspiration injector cannula used for?

It is used to collect and place fat in fat transfer procedures. The long opening lays a broad ribbon of graft as the cannula withdraws, filling wide recipient areas in fewer passes, and the same aperture aspirates efficiently enough to harvest moderate volumes without changing instruments.

Why does opening length matter on an injector?

A compact opening lays a narrow thread of fat; a long opening lays a broader flatter ribbon, because graft leaves along the whole aperture as the cannula withdraws rather than from one point. Long apertures fill wide areas evenly; small openings give finer control in thin tissue.

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. A sample also lets you run the steel hub through your own sterilization protocol before a bulk order.

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.
