The Stevens Style Liposuction Cannula is a multi-port aspiration cannula used to remove subcutaneous fat under vacuum during liposuction and body contouring. Its defining feature is the port sequence along the shaft: one upper central long hole nearest the tip, then a Mercedes three-port group, then four round holes set in a line further back. It is used by plastic surgeons, aesthetic surgeons and body contouring clinics, and is supplied in bulk to distributors and hospital groups worldwide.
Surgeons also refer to this instrument as a Mercedes tip liposuction cannula, a multi-port suction cannula, or a multi-hole lipo cannula.

Multi-Port Mercedes Tip Liposuction Cannula in German Stainless Steel
Port layout is what separates one aspiration cannula from another. A single-hole cannula draws fat from one point, so the surgeon must make more passes to clear an area evenly. The Stevens style spreads the aperture along the shaft instead, so each pass draws from a longer column of tissue and the removal is more even across the treated area.
How the Port Sequence Works
Reading from the tip backward, the first opening is a single long hole set on the upper surface. Because it is 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 and edge blending matter most. Behind it sits the Mercedes group, three ports arranged around the shaft, which is the pattern that carries most of the flow. Behind the Mercedes group, four round holes are set in a line along the shaft, extending the working aperture further back so the cannula keeps drawing throughout the stroke rather than 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.

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 and secondary liposuction in fibrous tissue, using the bullet tip profile
Material and Sterilization
Each cannula is made from German stainless steel with a smooth passivated surface that resists corrosion and pitting through repeated cleaning cycles. The cannulas are reusable and can be steam autoclaved at 134°C. Clean immediately after use, flush the lumen and every port, 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 the instrument goes into the autoclave.
How to Choose
Diameter controls how fast fat is removed and how much contour irregularity is possible; length controls reach. 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. Match the fitting to the equipment already in your theater.

Frequently Asked Questions
What is a Stevens style liposuction cannula used for?
It is used to remove subcutaneous fat under vacuum during liposuction and body contouring. The port sequence runs from a single long hole on the upper surface near the tip, through a Mercedes three-port group, to four round holes in a line further back, so the cannula draws fat along the length of each pass rather than from a single point.
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 liposuction cannula autoclavable?
Yes. All Healermed liposuction cannulas are 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 the cannula fully. 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, 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. Tell us the diameter, length, tip profile and fitting you want to evaluate and we will confirm what can be sent. Testing a sample before a bulk order is the fastest way to check port finish, edge deburring and hub fit against your own equipment.
