The Deep Sharp Cut Dissector With One Central Hole Injector Injector Cannula with Universal Luer Lock fitting is used to place fat in fat transfer and fat grafting. It is listed under Deep Sharp Cut Dissector With One Central Hole Injector Cannulas, part of the Healermed Liposuction Cannulas and Accessories range.

Deep Sharp Cut Dissector With One Central 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.

Why a Dissector Carries an Injection Port

This instrument combines two jobs that normally need two passes with two instruments: it releases fibrous tissue with a sharpened dissecting edge, and it places graft through a single central opening behind that edge.

The reason to combine them is the recipient site. Scarred and contracted tissue will not accept a graft until the bands holding it down are divided; fat injected into an unreleased pocket has nowhere to sit and is squeezed back out. The usual sequence is to release with a dissector, withdraw, change instruments, and inject. Doing both on one pass means the graft goes into the space at the moment it is created.

The single central opening is deliberate. Because this instrument is used in released scar, the surgeon needs to place small, exact amounts and see the tissue respond, not fill a pocket. One opening lays one thread per withdrawal at a rate the surgeon can judge.

The sharpened edge demands the same respect as any dissector: deep plane, edge oriented away from the skin, advanced deliberately rather than pushed, and out of service once dulled. It is not a general-purpose injector.

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 The cannula is advanced through the recipient plane, and fat is laid down as it is withdrawn, so the graft fills the tunnel the cannula has just made rather than being forced into tissue ahead of it.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
• ✔ Sharpened edge releases fibrous bands so the recipient site will accept graft
• ✔ Single central opening places the graft into the space as it is created
• ✔ Removes the instrument change between release and injection
• ✔ Deep-plane instrument used with the edge oriented away from the skin

Specifications

Clinical Applications

• Grafting into scarred or contracted recipient sites
• Contour deformity correction after previous surgery
• Release and fill in one pass where the pocket must be created first
• Deep-plane work with the 1.6mm to 3.0mm 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. Inspect the cutting edge under magnification at every cycle: a nicked or dulled edge tears tissue instead of dividing it. Flush the lumen and the central opening until the water runs clear, since graft residue sits behind the edge.

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 dissector one central hole injector cannula used for?

It is used to release fibrous bands in a scarred recipient site and place fat graft into the space created, in one pass. The sharpened edge divides the tissue and the single central opening behind it lays a controlled thread as the cannula withdraws.

Why combine a dissector and an injector in one instrument?

Scarred tissue will not accept a graft until the bands holding it are divided, and fat injected into an unreleased pocket is squeezed back out. Combining them means the graft enters the space at the moment it is created, without withdrawing and changing instruments between the two steps.

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.
