Two Holes In Line Injector Cannula

Liposuction Cannulas and Accessories › Two Holes In Line Injector Cannulas › Two Holes In Line Injector Cannula

A two holes in line injector cannula has two openings set in the same straight line on one side of the shaft, used to place fat in fat transfer and fat grafting. Two threads are laid per withdrawal, covering a recipient area in fewer passes while both stay aimed the same way. It sits in the Two Holes In Line Injector Cannulas category, part of the Healermed Liposuction Cannulas and Accessories range.

Two Holes In Line Injector Cannula in German Stainless Steel

How Two Openings In Line Place Fat

Two openings, both on the same side of the shaft and set in one straight line. As the cannula withdraws, each opening lays its own thread, and because they share a side both threads go the same way.

That is the difference from a single hole injector. Two deposits per pass cover a recipient area in roughly half the passes, which matters when the graft volume is substantial and the number of withdrawals is what limits the case. The threads sit parallel and close, so the fill is even rather than lumpy.

Keeping both openings on one side preserves the aiming that makes an injector controllable. Rotate the shaft and both threads redirect together, deep or superficial, exactly as with a single opening. Openings on opposite sides would place fat in two planes at once and take that choice away.

Two rather than more is the restraint. The surgeon still knows what was placed on each withdrawal. The closed blunt tip separates the plane without dividing vessels or nerves.

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 The cannula is advanced through the recipient plane, and fat is laid down as it is withdrawn, so the graft fills the tunnel the cannula has just made rather than being forced into tissue ahead of it.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

• ✔ Two openings lay two parallel threads on each withdrawal
• ✔ Covers a recipient area in roughly half the passes of a single hole injector
• ✔ Both openings on one side, so rotating the shaft aims the graft together
• ✔ Closed blunt tip separates the plane without cutting

Clinical Applications

• Body fat grafting where volume has to be placed evenly
• Gluteal and breast fat transfer with the larger diameters
• Recipient areas where pass count limits the case
• Facial work with the 1.2mm 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. Both openings sit on the same side, so hold that side down while flushing to be sure water runs through each rather than past them, and check both edges under light before sterilization.

Frequently Asked Questions

What is a two holes in line injector cannula used for?

It is used to place fat in fat transfer and fat grafting procedures. Two openings in line lay two parallel threads on each withdrawal, so a recipient area is filled in fewer passes while both deposits stay aimed the same way and can be directed by rotating the shaft.

What is the difference between two holes in line and two holes on opposite sides?

Two holes in line sit on the same side, so both threads go the same way and rotating the shaft aims them together. Openings on opposite sides deposit into two planes at once, which removes the surgeon's control over where the graft goes on each withdrawal.

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, length and fitting you want to evaluate and we will confirm what can be sent.

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.
