Blunt Single Hole Injector Cannula – Universal Luer Lock

Liposuction Cannulas and Accessories › Blunt Single Hole Injector Cannulas › Blunt Single Hole Injector Cannula – Universal Luer Lock

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

Blunt Single Hole Injector Cannula — Universal Luer Lock

Luer lock is a standard, but tolerances differ between brands, and a hub cut to the tight end of the band can seat poorly on some syringes. Under injection pressure a poor seat does not merely feel loose, it leaks graft at the hub. A universal hub is machined to sit centrally in that tolerance band so it locks properly across whatever syringe stock is on the shelf.

What a Single Side Opening Does on an Injector

One blunt opening, set on the side of the shaft rather than at the tip, behind a fully closed nose. It is the plainest injector we make and the one most surgeons reach for by default.

A side opening directs the graft sideways as the cannula withdraws rather than back along the tunnel. Rotating the shaft aims that delivery: opening down and the fat goes deep, opening up and it goes toward the skin. On a recipient site being built in layers that control is the whole point.

One opening means one thread per pass, of a size the surgeon learns and can predict. Nothing is deposited from a second point that has to be accounted for, which is what makes single-hole injectors the instrument for careful layering rather than filling volume quickly.

The closed blunt nose does the rest: it separates the recipient plane without dividing vessels or nerves, so the cannula can be advanced repeatedly through the same site to cross and layer threads.

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 The cannula is advanced through the recipient plane, and fat is laid down as it is withdrawn, so the graft fills the tunnel the cannula has just made rather than being forced into tissue ahead of it.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

• ✔ Universal Luer lock hub seats correctly across grafting syringe brands
• ✔ One opening lays a single predictable thread per pass
• ✔ Rotate the shaft to direct the graft deep or toward the skin
• ✔ Closed blunt nose separates the recipient plane without cutting
• ✔ Blunt edge applies no cutting force to the graft

Specifications

Clinical Applications

• Layered fat grafting where each thread must be placed deliberately
• Facial fat transfer including cheek, temple and jawline
• Recipient sites being built up over multiple crossing passes
• Fine work with the 1.0mm to 2.0mm 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. One opening and a closed tip make this the simplest injector to clean, but the lumen still holds graft residue, so flush from the hub until the water runs clear and inspect the opening under light at each cycle.

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 blunt single hole injector cannula used for?

It is used to place fat in fat transfer and fat grafting procedures. One blunt opening on the side of the shaft lays a single thread as the cannula withdraws, and rotating the shaft aims that delivery deep or superficial so the recipient site can be built in deliberate layers.

Why choose a single hole injector over a two hole one?

One opening lays a single thread per pass, so the surgeon knows exactly what was placed and where. Two openings place two threads at once, which fills faster but means accounting for a second deposit on every withdrawal. Single hole is the instrument for careful layering; two hole is for covering an area.

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 against the syringe brands you actually stock confirms the universal hub fits your supply.

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.
