Toomey Syringe: Hubs, Locks and Adapters for Liposuction
Oct
A Toomey syringe is a large syringe, usually 60 ml, with a wide tapered catheter tip in place of the narrow luer nozzle found on a standard syringe. Hospitals use it for irrigation, and in liposuction and fat transfer it is the barrel that harvested fat is drawn into and pushed back out of. Adas Instruments does not make the syringe itself. We make the steel and aluminium parts that attach to it: cannulas with a Toomey hub, plunger locks, injection guns and transfer adapters.
That split decides how a Toomey setup should be bought. The syringe is a disposable from a medical supplier. Everything that touches it and goes back into the autoclave is a reusable instrument, and that is the part where a wrong fitting costs a case.
Key takeaways
- The Toomey tip is wide, so fat passes through it without being forced through a narrow luer bore.
- A cannula needs a Toomey hub, or a wide bore Super Luer Lock hub, to seal on a Toomey syringe. A standard luer hub will not.
- A plunger lock holds the vacuum during manual harvest so the surgeon is not holding the plunger back by hand.
- Fat moving from a 60 ml barrel into small injection syringes needs a Toomey to luer transfer, which is where many setups leak.
What a Toomey Syringe Is, and Where It Came From
Outside the operating theater, the Toomey is best known as an irrigation syringe. A typical listing in the US device database, such as this Monoject 60 ml Toomey tip syringe record, describes a sterile, single use 60 ml barrel with a Toomey tip. Wards use them for bladder and wound irrigation because the wide tip moves a lot of fluid quickly.
Fat surgeons borrowed it for the same reason. Fat is thick. Drawing it through a narrow luer opening is slow, and pushing it back out through the same opening needs force. A Toomey barrel gives a wide path in and a wide path out, so it became the standard reservoir for syringe harvest and for moving larger volumes during fat transfer.
Toomey Tip vs Luer Tip
| Feature | Toomey tip | Luer tip |
|---|---|---|
| Opening | Wide tapered catheter tip | Narrow nozzle, slip or threaded lock |
| Common barrel size | 60 ml | 1 ml to 60 ml |
| Strength in fat work | Harvest and moving larger volumes | Fine injection in small aliquots |
| Cannula hub needed | Toomey hub or Super Luer Lock | Luer lock hub |
| How the two meet | Toomey to luer transfer adapter | Luer to luer transfer adapter |
Most fat transfer setups use both. The Toomey handles the volume half of the job, the luer handles the precision half, and the transfer between them is the step to plan properly.
The Cannula Hub Is the Part That Matters
A cannula seals on a Toomey syringe only if its hub matches the tip. On our harvest cannulas the hub is chosen when the order is placed. The Sorensen harvester cannula, for example, is listed with Luer Lock, Toomey, Power Fix and threaded hub options, in diameters from 2.5 to 4.0 mm and lengths from 15 to 30 cm. The Toomey hub on these cannulas is made for 60 cc Toomey syringes.
There is a second route. Our Super Luer Lock hub is a wide bore connection that fits both Toomey and luer lock syringes, which suits a practice that does not want two sets of cannulas. On the Mercedes liposuction cannula the hubs are color coded, so a scrub nurse can tell a Toomey hub from a luer hub on the tray without reading the label. The large volume harvester cannula and the rest of our aspiration cannula range follow the same hub choices.
The ordering mistake we see most often at Adas Instruments is a cannula bought for its tip pattern with the hub left at the default. The tip is right, the hub is luer, and the cannula arrives unable to seal on the Toomey barrels the clinic already stocks. Name the syringe with the order and the hub question answers itself.
Build a Toomey setup from the maker
Every reusable part in this guide is made in the Adas Instruments workshop. Harvest cannulas with a Toomey hub from 32 dollars, the syringe stop lock from 18.50 dollars, the fat injection gun at 125 dollars.

Holding the Vacuum: Plunger Locks
Syringe harvest works by pulling the plunger back to create negative pressure, then moving the cannula through the fat. Holding the plunger back by thumb for a whole harvest tires the hand and lets the pressure drift. Our syringe stop lock holds the plunger at the position the surgeon sets. It is stainless steel, autoclavable, and made in four sizes for 10 cc, 20 cc, 50 cc and 60 cc syringes, so the 60 cc lock fits a standard Toomey barrel.
Between stages, a filled barrel often has to stand while fat settles. A syringe stopper cap closes a luer barrel; Toomey barrels are usually capped with the cap supplied by the syringe maker, or stood upright in a decant stand.
Moving Fat From Toomey to Luer
Fat is harvested in volume and injected in small amounts, so at some point it has to leave the 60 ml barrel and enter 1 ml, 3 ml or 10 ml luer syringes. That transfer should stay closed, with no open pouring. Our facial cannula set includes a decant stand and an anaerobic transfer connector from a 60 cc Toomey to luer, along with Super Luer Lock injection cannulas from 0.9 mm.
Once the fat is in luer syringes, luer to luer transfer adapters move it between syringes for mixing or emulsifying. We make them in hole sizes from 1 mm to 3 mm, color coded by size, in anodized aluminium. The nano fat transfer kit carries a set of these adapters with a filtration system for nano fat work.
Injection Guns for Larger Barrels
Pushing fat back out of a large barrel by hand gives uneven volumes from one pass to the next. A ratcheting gun gives a set amount per squeeze. Our fat injection gun comes in two frame sizes, one for 10 cc and 20 cc syringes and one for 50 cc and 60 cc syringes, with a black or silver handle. Make sure the frame matches the barrel before the order goes in.
Common Mistakes With a Toomey Setup
- Wrong hub on the cannula. A luer hub will not seal on a Toomey tip. Name the syringe type when ordering.
- Mixed hubs on one tray. If both hub types are in use, keep them separate or use color coded hubs so they are not swapped mid case.
- Plunger lock in the wrong size. A 50 cc lock on a 60 cc barrel will not hold. Order by barrel size.
- Open transfer. Pouring fat from a Toomey into luer syringes exposes it to air. Use a closed Toomey to luer connector.
- Worn hubs left in service. A hub that has started to weep at the joint loses vacuum on every pass. Inspect hubs at the same time as tips.

Frequently Asked Questions
What is a Toomey syringe?
A Toomey syringe is a large syringe, usually 60 ml, with a wide tapered catheter tip instead of a narrow luer nozzle. It is used for irrigation in hospitals and as the harvest and transfer barrel in liposuction and fat grafting.
What is a Toomey syringe used for in liposuction?
In syringe liposuction and fat transfer, the Toomey barrel collects harvested fat and holds it before transfer or reinjection. Its wide tip lets thick fat pass more easily than a luer tip.
What is the difference between a Toomey tip and a luer tip?
A Toomey tip is a wide tapered catheter tip, while a luer tip is a narrow nozzle that slips or screws onto a luer fitting. Cannulas and adapters must match the tip type to seal.
Can I use a luer lock cannula with a Toomey syringe?
Not directly, because a standard luer hub will not seal on a Toomey tip. Order the cannula with a Toomey hub or a wide bore Super Luer Lock hub, or use a Toomey to luer adapter.
What size is a Toomey syringe?
The usual size in fat work is 60 ml. Accessories such as our syringe stop lock and fat injection gun are sized to match, with versions for 50 cc and 60 cc barrels.
