Cobra Round Tip Cannula Threaded Fitting

The Cobra Style Round Tip Liposuction Cannula with Threaded Fitting is an aspiration cannula with a fully domed, closed tip, used to remove subcutaneous fat under vacuum. Instead of a Luer hub, the shaft ends in a machined screw thread that seats into a threaded handle or tubing connector, giving a rigid joint with no play between hand and tip. It is listed under Cobra Style Round Tip Liposuction Cannulas, part of the Healermed Liposuction Cannulas and Accessories range.

Buyers also search for this instrument as a round tip lipo cannula, a blunt tip aspiration cannula, or an atraumatic liposuction cannula.

Screw-Thread Round Tip Cannula for Handle-Based Systems

A threaded fitting turns the cannula and the handle into a single rigid unit with no rotational play. That matters most in exactly the work a round tip is chosen for: in a superficial plane the surgeon is steering by feel through small movements, and any slack at the joint is slack between the hand and the tip.

What the Round Tip Does

The round tip is a fully domed, closed end with no taper and no edge anywhere on it. That single detail decides how the cannula behaves at the moment of contact: it cannot catch, it cannot start a cut, and it cannot be led off the plane by a firm structure. It pushes tissue aside and lets the surgeon's line of travel decide the direction, rather than the tissue deciding it.

Compare it with a bullet tip. A bullet profile tapers to a narrower nose, which makes it easier to drive through scar and fibrous septa, at the cost of some of that forgiveness. A round tip needs a little more push in dense tissue, and gives back a far lower chance of a septum being divided or the tip skipping into a plane the surgeon did not choose.

That trade favours the round tip wherever the margin for error is smallest. In the superficial layer the skin is close and an irregularity is permanent. Over bony landmarks and near a neurovascular bundle the cost of a tip that catches is not a contour problem. In those places the surgeon wants the most forgiving nose available, and accepts the extra push.

Vacuum works through the side ports, not the end of the shaft. Because the tip itself is sealed, suction never pulls tissue against the leading point, which is what keeps a round-tip cannula from grabbing as it enters.

Key Features

• ✔ Machined screw thread seats rigidly into threaded handles and connectors
• ✔ No play between hand and tip during fine superficial passes
• ✔ Fully domed round tip with no taper and no edge — the most forgiving profile in the range
• ✔ Sealed tip so suction never pulls tissue against the leading point
• ✔ Blunt dissection through the plane, pushing vessels and nerves aside
• ✔ Deburred port edges for clean passage through fat
• ✔ One-piece German stainless steel shaft, fully reusable
• ✔ Custom diameters, lengths and port configurations available on request

Specifications

Clinical Applications

• Superficial liposuction where the skin is close and an irregularity is permanent
• Work over bony landmarks and near neurovascular bundles
• Arm, neck and submental contouring with the shorter, smaller-diameter sizes
• Facial and delicate-area contouring with the smallest 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 every port with clean water immediately after use and dry fully before autoclaving. Inspect the tip dome at each cycle: the round profile only works while it is smooth, and a dent or flat spot from a dropped instrument turns a forgiving tip into one that catches.

How to Choose

Order the threaded fitting if you already own handles that take a screw-in cannula, and send us your handle specification before ordering in quantity. Diameter sets how much fat comes out per pass and length sets the reach. For general body contouring of the abdomen, flanks and thighs, the 3.0mm to 4.0mm diameters in 25cm to 35cm are the usual working range. The 2.0mm to 2.5mm range in 15cm to 25cm suits arms, the neck and superficial refinement, which is where a round tip is chosen most often. The 1.0mm to 1.5mm diameters in 5cm to 12cm are for fine facial and submental work. Match the fitting to the syringe, vacuum line or handpiece already in your theater.

Frequently Asked Questions

What is a threaded fitting round tip cannula used for?

It is used to remove subcutaneous fat under vacuum when the cannula screws into a threaded reusable handle rather than attaching to a syringe. The rigid joint removes play between hand and tip, which helps in the fine superficial work a round tip is chosen for.

What is the difference between a round tip and a bullet tip cannula?

A round tip is fully domed with no taper; a bullet tip narrows to a nose. The round tip is more forgiving, since it pushes tissue aside rather than parting it, and is preferred in superficial and delicate planes. The bullet tip passes through scar and fibrous tissue with less force, which suits revision and dense areas.

Is this cannula autoclavable?

Yes. The instrument is fully reusable and can be steam autoclaved at 134°C. Flush the lumen and every port with clean water immediately after use, remove all residue before sterilization, and dry completely. Check the tip dome and port edges each cycle, since both affect how the cannula behaves in tissue.

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. This lets a small distributor start with a trial order and a larger importer scale up on the same terms.

Do you provide samples?

Yes. Samples are available on request and the buyer covers the shipping charges. Send us your handle specification along with the diameter and length you want to evaluate. Testing a sample first is the safest way to confirm the thread seats correctly in your handle.

Can I order a custom size?

Yes. Custom diameters, working lengths and port 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. Custom branding is also available for distributor and OEM orders.
