Adaptor Handle with Threaded Connection

What an adaptor handle with a threaded connection is

Liposuction cannulas come with different ends. Some carry a luer lock, some a fixed handle, and some a plain threaded hub that needs a handle screwed onto it before it can be used. This adaptor handle is for that last kind. It gives a threaded cannula a grip, and it gives the suction tubing somewhere to go.

Google AI Mode, read on 23 October 2026, describes the piece as a reusable part that makes an airtight, leak free seal between threaded cannulas and the suction tubing, a syringe or a powered system. The answer cites this listing of ours by name among its sources. Ours is the tubing version: thread at the front, hose barb at the back.

Buyers also search for the same part as a cannula adaptor or a cannula handle. The word adaptor matters, because the handle is what adapts one cannula system to the suction line, and the right one depends on the end the cannula carries.

Key design features

A threaded front

The front of the handle carries a threaded fitting. The cannula hub and this fitting screw together until they seat, and the thread holds it there for the whole case. Our earlier copy for this product describes the fitting as one that locks the cannula firmly in place, which is what a thread does better than a push fit. Before the first case, run each cannula you plan to use onto the handle by hand. A hub that turns freely all the way to the seat is on the right thread; one that binds after a turn belongs to another system and should not be forced.

A barbed nozzle for the tubing

At the back the handle narrows into a ribbed, tapered nozzle. Suction tubing pushes over the ribs and they hold it. The taper lets one nozzle take tubing a little larger or smaller at the bore, and the ribs keep it from pulling off while the line is under vacuum. Push the tubing on past the last rib rather than just onto the tip, because a short overlap is where a line under suction comes away.

A knurled grip and a thumb rest

The body is knurled along its length, a fine crosshatch cut into the surface, so it holds through a wet glove. Near the front there is a flat, oval recess where the thumb sits. In our photograph it is the one smooth patch on the body, and it gives the hand a fixed reference for which way the cannula ports face. Without it, a round body can roll a little in the fingers and turn the ports with it.

A gold finish

The handle has a gold colored finish over steel. On a tray it sets the threaded handle apart from the blue luer pieces at a glance, which helps when both kinds of cannula are in use on the same list. The finish is part of the product, not an option, and there is one size at 45 dollars.

What it is for, and what it is not for

Each connector in this family joins two particular things. The table sends the other jobs to the piece of ours that does them.

How it compares with the rest of the family

Five connecting pieces make up this family on our site. The ends are read off our own listing for each one, and the prices off each product’s order form.

Materials and finish

Every adaptor handle we make is formed from high quality medical grade stainless steel. The steel itself is made to a German specification. We do not publish a grade number.

The gold color is a finish over the steel body, and our earlier copy for this product gives it as gold plating. The knurling and the thumb rest are worked into that body, not added on, so there is no rubber sleeve on the grip to come loose or to hold fluid underneath it.

Caring for it

Unscrew the cannula and pull the tubing off as soon as the case ends. Flush water through the handle from the threaded end to the nozzle, then push a brush through the bore. Scrub the thread and the knurling with a soft brush, because tissue sits in both. Dry it, steam sterilize it on the normal instrument cycle, and store it with nothing attached. Start every cannula straight on the thread; a cross threaded fitting is the one thing that ends a handle early.

Ordering and wholesale

The adaptor handle with threaded connection is made by Adas Instruments in our own workshop and sold direct, which is why the price sits where it does against the catalog houses. Order one for a single tray, or in quantity for a hospital list or a distributor line. We do OEM work under your own brand and your own item numbers. Send us a sample and we will hold a run to your pattern rather than ours. Stock items ship from our own workshop. Backorder items take 10 to 12 working days to make. Every instrument carries a three year replacement warranty against manufacturing defects. Production is controlled under an ISO 13485 quality management system.

Frequently asked questions

What is an adaptor handle used for?

It joins a cannula with a threaded hub to the suction tubing and gives the surgeon a grip. The cannula screws on at the front, the tubing pushes onto the barbed nozzle at the back, and the connection stays airtight while the line is under vacuum.

Will the adaptor handle fit any threaded cannula?

Threads differ from maker to maker, so not every threaded cannula will fit. Pair it with the threaded fitting on our own cannula order forms. If your cannulas come from another maker, send us one and we will check the thread before you order.

Can I put a syringe on the adaptor handle?

No. The back of this handle is a barbed nozzle for suction tubing, not a luer fitting. To use a threaded cannula on a luer lock syringe, use our adaptor with luer lock connection, which has a thread at one end and a luer lock at the other.

What is the difference between a threaded and a luer lock cannula?

The difference is the end. A luer lock cannula has a small standard fitting that locks onto a luer handle or syringe with a short twist. A threaded cannula has a larger hub that screws onto a threaded handle. Each needs its own handle.

How do I clean an adaptor handle?

Take the cannula and the tubing off, flush water through from the thread to the nozzle, brush the bore, and scrub the thread and the knurled grip. Dry it and steam sterilize it with your other instruments, with nothing attached.
