Stevens Style Liposuction Cannula Threaded Fitting, one Long Hole, Mercedes and 4 Round Ports

The Stevens Style Liposuction Cannula with Threaded Fitting is a multi-port aspiration cannula used to remove subcutaneous fat under vacuum during liposuction and body contouring. Instead of a Luer hub, the shaft ends in a machined screw thread that seats directly into a threaded handle or tubing connector, giving a rigid, wobble-free joint. It suits surgeons using handle-based suction systems and is supplied in bulk to distributors worldwide. See the full Stevens Style Liposuction Cannula range for other fittings.

Buyers also search for this instrument as a screw-fit lipo cannula, a threaded hub aspiration cannula, or a Mercedes tip suction cannula.

Screw-Thread Liposuction Cannula for Handle-Based Suction Systems

A threaded fitting turns the cannula and the handle into a single rigid unit. There is no rotational play at the joint, so the direction the surgeon points the handle is exactly the direction the tip travels. Over long passes through the abdomen or thigh, that rigidity gives better control of the plane than a push-on connection.

How the Port Sequence Works

Reading from the tip backward, the first opening is a single long hole on the upper surface. Being elongated rather than round, it draws along a continuous stretch of tissue instead of from one spot, which is what makes it useful at the leading edge of the pass where feathering matters most. Behind it sits the Mercedes group, three ports arranged around the shaft, which carries most of the flow. Behind that, four round holes are set in a line along the shaft, extending the working aperture so the cannula keeps drawing throughout the stroke instead of only at the tip.

Blunt Tip or Bullet Tip

Both tip profiles are available on this cannula. The blunt tip is fully rounded and is the safer general-purpose choice, because it pushes vessels and nerves aside rather than dividing them. The bullet tip has a slightly tapered nose, which makes entry through fibrous or scarred tissue easier and needs less force on each pass. Select the tip profile when you order.

Key Features

• ✔ Machined screw thread seats rigidly into threaded handles and connectors
• ✔ No rotational play between cannula and handle during long passes
• ✔ Graduated port sequence — single upper long hole, Mercedes group, then 4 in-line round holes
• ✔ Longer working aperture draws fat evenly across the whole stroke
• ✔ Choice of blunt tip or bullet tip on any size
• ✔ One-piece German stainless steel shaft, fully reusable
• ✔ Custom diameters, lengths and port patterns available on request

Clinical Applications

• Body contouring liposuction of the abdomen, flanks, back and thighs
• Arm, submental and neck liposuction with the shorter, smaller-diameter sizes
• Fat harvesting for grafting procedures
• Revision liposuction in fibrous tissue, using the bullet tip profile

Material and Sterilization

The cannula is made from German stainless steel with a passivated surface that resists corrosion through repeated autoclave cycles. It is reusable and can be steam sterilized at 134°C. Flush the lumen and every port with clean water immediately after use and dry fully before autoclaving. A multi-port cannula has more openings to clear than a single-hole design, so check each port under light before sterilization.

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. Diameters of 3.0mm to 6.0mm in 25cm to 35cm are the working range for large body areas such as the abdomen, flanks and thighs. The 1.8mm to 2.5mm range in 15cm to 25cm suits arms, the neck and superficial refinement. The 1.0mm to 1.5mm diameters in 5cm to 12cm are for fine facial and submental work. Choose the blunt tip for general use and the bullet tip when passing through fibrous or previously operated tissue.

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 threaded fitting liposuction 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 screw thread creates a rigid joint with no rotational play, which helps the surgeon hold the intended plane over long passes.

What is the difference between a Mercedes tip cannula and a single-hole cannula?

A Mercedes tip has three ports grouped around the shaft; a single-hole cannula has one. The three-port group moves more fat per pass and spreads the draw around the shaft, which reduces the chance of over-resection at one point. A single hole gives finer, slower control and is usually chosen for superficial refinement.

Should I choose a blunt tip or a bullet tip?

Choose the blunt tip for general liposuction. Its fully rounded nose pushes vessels and nerves aside rather than dividing them, which is the safer default. Choose the bullet tip when working through fibrous, scarred or previously operated tissue, where the tapered nose needs less force on each pass. Both profiles are available in every size.

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 each of the eight openings under light, because a multi-port cannula holds residue in more places than a single-hole design.

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, tips 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, length and tip profile 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 patterns 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.
