A liposuction cannula is a thin, hollow stainless steel tube that a surgeon passes through a small incision to aspirate fat during liposuction. Cannulas vary by diameter, length, tip design and material, and the right choice depends on the treatment area, the technique being used, and whether the instrument is single-use or reusable.
That definition makes cannula selection sound simple. It isn't — the right cannula depends on where you're working, how dense the adipose tissues are and whether you're delivering fluid or removing tissue. Get any one of those wrong and it shows up as bruising, uneven contours, or a longer recovery.
This guide from Surgical Green is written for the people who have to stock the tray, not just use it: surgeons building a personal set, theatre managers doing procurement, and clinic buyers trying to work out what "3.5mm Mercedes tip" actually means before they order forty of them.
Understanding the types of liposuction cannulas on the market — and the wider set of liposuction instruments they belong to — makes that tray decision a lot easier.
What Is a Liposuction Cannula and How Does It Work?
A cannula connects to a suction source — a syringe, a vacuum aspirator, or a
power-assisted handpiece — and is moved back and forth through the fat layer in a fan-like pattern. Openings near the tip, called ports, pull fat cells into the cannula and out of the body as the surgeon works.
Everything about a cannula's design exists to answer one question: how do you remove fat efficiently without damaging the blood vessels, nerves, and connective tissue around it?
Diameter, tip shape, port count, and material are really just four different answers to that same problem.
That's why they're worth understanding together rather than as separate spec sheets — especially for an instrument you'll be restocking often. Few liposuction instruments turn over as fast in an aesthetic theatre, so it's worth getting this decision right.
Types of Liposuction Cannulas
Most surgical trays contain more than one of the types of liposuction cannulas available, because no single cannula does every job well.
|
Type |
What it's for |
|
Standard cannula |
For larger surface areas such as the abdomen, flanks and thighs. |
|
Microcannula |
Delicate, high-precision work on the face, neck, arms and ankles, Used for fat grafting or SVF injection. |
|
Tumescent (infiltration) cannula |
Delivering tumescent fluid before fat removal begins |
|
Power-assisted cannula |
Attaches to a simple power handpiece or to a vibrating/oscillating/laser assisted hand piece for quick & effective dense fibrous tissue breakdown. |
|
Specialized cannula |
Purpose-built shapes for techniques like high-definition liposculpture or fat (adipose tissues) harvesting. |
Tumescent liposuction — the technique behind that first row — involves injecting a solution.
of saline, local anesthetic and adrenaline into the fat layer before any fat is removed. It numbs the area, constricts blood vessels to reduce bleeding, and softens the fat so it aspirates more easily. That's why infiltration cannulas (for delivering the fluid) and standard cannulas (for removing fat) are used one after the other, not interchangeably.
Power-assisted instruments deserve their own clarification too, since "manual vs powered" is a common point of confusion. Manual cannulas rely entirely on the surgeon's hand movement plus a syringe or vacuum aspirator for suction.
Power-assisted cannulas add a motorized handpiece that oscillates or vibrates the tip, reducing physical effort on denser or fibrous fat. Surgical Green's current range across all seven categories is built around manual, vacuum-based cannulas.
Within those categories, surgeons also talk about cannulas by their tip name rather than their category — this is where it gets confusing for anyone new to procurement. A Mercedes tip (three-port, named for its resemblance to the car badge) is a workhorse for even,
general-purpose extraction, and a double Mercedes variant is available where more aggressive removal is needed.
A Cobra tip — offered with either a round or a beveled edge — has a more aggressive opening built for stubborn, fibrous areas.
Beyond those two, the wider family includes basket-shaped, Spiral Port , Stevens style, and candy cane tips, each varying port count and placement to change how aggressively and evenly the cannula clears fat. None of these names are standardized across every manufacturer, so it's the port count and tip shape that matter more than the name attached to it.
Cannula Diameter & Length — Which Size for Which Area
Diameter is the single biggest factor in how a cannula performs, and it's usually the first thing a surgeon specifies when ordering.
|
Diameter |
Typical use |
|
Supermicro 0.5mm (23GA) - 1.0mm (19GA) Micro 1.2mm (18GA) - 1.6mm (16GA) |
Used for nano or micro fat grafting and high-definition sculpting on the face, neck, chin, eyes, arms and ankles — where fine control matters more than speed. Suited to micro fat grafting and detailed contouring on smaller treatment zones like the face, neck, arms and ankles. |
|
Standard — 2–4.5mm |
Abdomen, flanks, back, thighs; the general-purpose range most trays are built around |
|
Large-bore — over 4.6 6mm |
High-volume debulking where speed matters more than fine contouring |
The relationship is straightforward: smaller diameters give the surgeon more control and cause less tissue disruption, but move less fat per pass. Larger diameters clear volume faster but demand more skill to avoid leaving surface irregularities
Length works alongside diameter — longer cannulas reach deeper or more posterior areas (the back, for instance) without repositioning the incision, while shorter cannulas suit small, localised treatment zones like the chin. Getting diameter right is often the single biggest lever a buyer has over how a set of liposuction instruments performs in theatre.
Cannula Material — Why Stainless Steel Still Wins
Almost every reusable liposuction cannula on the market is made from surgical-grade, non-magnetic stainless steel, and there's a practical reason it hasn't been displaced: it survives repeated autoclave cycles without corroding, and it holds a fine edge or polish where the design calls for one.
It's also stiff enough to give the surgeon accurate tactile feedback through the handle — you can feel the difference between fat and fascia through a well-made steel cannula in a way that's harder to replicate in lighter alloys.
Disposable cannulas are typically stainless steel as well, but manufactured to a lower cost point since they're built for a single use rather than hundreds of sterilisation cycles.
Single-Use vs Reusable Cannulas — Which Is Right for Your Clinic?
This is one of the most common procurement questions we get, and the honest answer is: it depends on your case volume and your sterilisation setup, not on which option is "better."
Reusable cannulas cost more upfront but work out cheaper per procedure over hundreds of uses — provided your clinic has a reliable autoclave workflow and someone responsible for inspecting instruments between cycles. They're the standard choice for high-volume practices and hospital theatres.
Single-use cannulas cost less to stock, remove any risk of cross-contamination between patients, and need no sterilisation turnaround — which matters for smaller clinics, satellite locations, or anyone who wants zero variability in tip sharpness from one procedure to the next.
Expect to pay roughly £10–£25 per single-use cannula depending on tip style and size, against roughly £35–£50 for an equivalent reusable one built to survive hundreds of autoclave cycles. The trade-off is a higher per-procedure cost on single-use if your volume is high enough to make reusables pay for themselves.
Many practices run a hybrid approach: reusable standard cannulas for routine work,
single-use for anything where infection control margins are tighter, or as backup stock during busy periods. Either way, this is a decision worth making for your liposuction instruments as a set, not cannula by cannula.
Tip Design — Blunt, Sharp & Multi-Port Explained
Tip design is where a lot of buyers get tripped up, because "infiltration cannula" and "standard cannula" sound like they should be interchangeable, and they're not.
Infiltration cannulas have a blunt tip. Their job is to distribute tumescent fluid — the saline, lidocaine and adrenaline mix that numbs the area and constricts blood vessels before fat removal starts — evenly through the treatment zone. A blunt tip does this gently, without cutting or aspirating tissue on the way in.
Standard and harvesting cannulas have a sharp, bevelled tip. Their job is the opposite: to cut through and aspirate fat efficiently. Using a blunt infiltration cannula for fat removal, or a sharp harvesting cannula for fluid infiltration, is a mismatch that shows up immediately in how the instrument performs.
Port configuration matters too. A single-port tip gives the surgeon direct, controlled removal
— useful for precise sculpting. A multi-port tip, like the Mercedes design, spreads suction across several openings at once, which tends to produce a smoother result with less risk of visible grooving, at the cost of some directional control.
How to Choose the Right Cannula for a Procedure
The right cannula for a procedure comes down to four factors: treatment area, fat density, technique, and clinic setup. Matching those against the rest of your liposuction instruments, here's how each one plays out:
1. Where on the body? Delicate areas call for microcannulas; larger areas can take standard or large-bore instruments.
2. What's the fat like? Soft, easily aspirated fat suits a standard cannula; dense, fibrous fat (common on the back or male chest) often benefits from power-assisted instruments.
3. What's the technique? Tumescent liposuction needs infiltration cannulas before any aspiration cannula is used. Fat grafting needs harvesting cannulas with a gentler port design to keep cells viable for reinjection.
4. What's the setup? A high-volume practice with in-house sterilisation is well suited to a reusable core set; a lower-volume or multi-site clinic may lean toward single-use.
Most working trays end up with a small combination rather than one cannula doing everything — a couple of infiltration cannulas, a standard set across two or three diameters, and one or two specialized tips for the procedures a surgeon performs most often. Building a tray this way, around the types of liposuction cannulas you actually use, tends to work out cheaper than buying one of everything up front.

Sterilising & Maintaining Liposuction Cannulas
Liposuction cannulas should be rinsed immediately after use, ultrasonically cleaned, inspected, and autoclaved — Surgical Green's own instrument care guidance points to the usual 20-minute autoclave cycle for these liposuction instruments. Here's the standard protocol, step by step:
1. Rinse immediately after use — fat and blood residue set hard inside the lumen if left to dry, and are far harder to remove once they do.
2. Ultrasonic cleaning before autoclaving, to clear debris from inside the cannula that manual brushing can miss.
3. Inspect the tip and lumen for burrs, bends, or blocked ports before every use — a partially blocked cannula delivers uneven suction without any obvious external sign.
4. Autoclave using a full cycle (a 20-minute steam cycle is standard for stainless steel surgical instruments) — never lock an instrument during autoclaving, as this stops steam reaching the metal-to-metal surfaces.
5. Store dry, in sealed sterile packaging, away from moisture that encourages corrosion over repeated cycles.
It's also worth keeping the distinction Surgical Green draws on its own care guidance: disinfected is not the same as sterile. Disinfection clears visible contamination in around 10 minutes, but only a full autoclave cycle renders an instrument sterile — the term that matters for anything going back into a patient.
Instruments that are dropped, bent, or show pitting on the shaft should be retired rather than pushed through another cycle — a compromised cannula affects suction consistency in ways that are hard to diagnose mid-procedure.

Sourcing Liposuction Cannulas in the UK — What to Look For
If you're buying rather than just using, a few checks are worth doing before you commit to a supplier:
● UKCA marking and MDR compliance on every instrument, confirming it meets UK and EU medical device requirements
● Material — ask specifically for non-magnetic, surgical-grade stainless steel rather than taking "surgical steel" at face value
● Warranty and returns policy — Surgical Green backs its instruments with a lifetime warranty against manufacturing defects, plus a 30-day return window on most items (note: single-use cannulas aren't eligible for return)
● Stock depth across sizes and tip types — a supplier who only carries one or two diameters will leave gaps in your tray
● UK-based support — faster replacement turnaround than ordering from an overseas manufacturer each time

Frequently Asked Questions
What are the different types of cannulas used in liposuction? In short, the main types of liposuction cannulas are standard cannulas for general fat removal, microcannulas for delicate or precision work, infiltration (tumescent) cannulas for fluid delivery, power-assisted cannulas for denser fat, and specialised tips — Mercedes and Cobra among the most common — built for specific techniques.
What is tumescent liposuction? Tumescent liposuction is the standard technique where a solution of saline, local anaesthetic and adrenaline is injected into the fat layer via an infiltration cannula before fat removal begins. It numbs the area, reduces bleeding, and softens the fat so a standard or harvesting cannula can aspirate it more easily.
What's the difference between manual and powered liposuction instruments? Manual cannulas rely on the surgeon's hand movement plus a syringe or vacuum aspirator for suction. Power-assisted cannulas add a motorised handpiece that oscillates or vibrates the tip, helping break up denser or fibrous fat with less physical effort. Surgical Green's current range is built around manual, vacuum-based cannulas.
Where can I buy liposuction cannulas and instruments in the UK? Surgical Green supplies UKCA-marked, MDR-compliant liposuction cannulas and instruments — including infiltration cannulas, fat grafting cannulas, single-use options, and complete suggested sets
— to surgeons and clinics across the UK.
What is the typical cost range for a single-use liposuction cannula? Single-use liposuction cannulas typically cost around £10–£25 each depending on tip style and size, compared with roughly £35–£50 for a reusable cannula built to survive hundreds of autoclave cycles.
How do surgeons choose the right liposuction cannula for a procedure? Choice comes down to treatment area, fat density, the technique being used (standard, tumescent,
power-assisted), and clinic setup. Delicate areas call for smaller-diameter microcannulas; larger, fibrous areas often need standard or power-assisted instruments.
What's the difference between an infiltration cannula and a standard cannula? Infiltration cannulas have a blunt tip designed to distribute tumescent fluid gently. Standard cannulas have a sharp, bevelled tip designed to cut through and aspirate fat. They're used at different stages of the same procedure and aren't interchangeable.
Single-use or reusable — which cannula should a clinic buy? Reusable cannulas cost less per procedure over time but require a reliable sterilisation setup. Single-use cannulas cost more per procedure but remove cross-contamination risk and need no autoclave turnaround — a common choice for lower-volume or multi-site clinics.
What material are liposuction cannulas made from? The overwhelming majority are non-magnetic, surgical-grade stainless steel, chosen for autoclave compatibility, corrosion resistance, and the tactile feedback it gives surgeons during the procedure.
How should liposuction cannulas be sterilised? Rinse immediately after use, clean ultrasonically to clear the internal lumen, inspect for damage, then run a full autoclave cycle (20 minutes is standard for stainless steel surgical instruments) and store dry in sealed sterile packaging.
