Angled Tumescent Cannula – Threaded Fitting

The Angled Tumescent Infiltration Cannula with Threaded Fitting is a blunt-tip cannula with a bent working shaft, used to deliver tumescent or wetting solution before liposuction. 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 joint that holds the bend pointing where the surgeon set it. See the full Angled Tumescent Infiltration Cannulas range for other fittings.

Buyers also search for this instrument as a screw-fit angled cannula, a threaded hub bent infiltrator, or an angled wetting solution cannula.

Screw-Thread Angled Cannula for Handle-Based Infiltration 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. On an angled shaft this matters more than usual: if the joint rotates, the bend swings out of plane and the pass no longer goes where it was aimed.

What the Angle Does

An angled cannula has a bend in the shaft, so the working section travels at an angle to the hub axis instead of running straight back from it. That changes the direction of the pass itself, which is the difference between an angled cannula and a bayonet one: a bayonet steps the shaft sideways and then runs parallel again, while an angle redirects where the tip actually goes.

The practical gain is reach. The body is curved, and a straight cannula entering a flank, hip or submental area has to be forced to an awkward wrist position to stay in the subcutaneous plane as the surface falls away. An angled shaft follows that curve instead of fighting it, so a single entry port covers more area and the surgeon's wrist stays in a neutral position through the pass.

The second gain is clearance at the skin. Because the hub sits at an angle rather than flat against the surface, the syringe or handpiece is held up and away from the area being filled. The surgeon is not pressing on tissue that is in the middle of taking up solution, which makes it easier to read turgor as the endpoint approaches.

The distal tip is closed and rounded. It separates the subcutaneous plane by blunt dissection as the cannula advances, pushing vessels and nerves aside rather than dividing them, and side holes along the working section release the solution along the length of the pass rather than at one point.

Key Features

• ✔ Machined screw thread seats rigidly into threaded handles and connectors
• ✔ No rotational play, so the bend stays in the plane the surgeon set
• ✔ Angled shaft follows a curved body surface instead of fighting it
• ✔ Wider coverage from one entry port with the wrist in a neutral position
• ✔ Hub sits up and away from the skin, so the hand does not press on filling tissue
• ✔ Closed blunt tip separates the plane without cutting vessels or nerves
• ✔ Side holes along the working section spread solution along the pass
• ✔ One-piece German stainless steel shaft, fully reusable

Specifications

Clinical Applications

• Tumescent infiltration of curved areas — flanks, hips, outer thighs
• Submental and neck infiltration where the surface falls away sharply
• Wetting solution delivery before power-assisted and syringe liposuction
• Covering a wide field from a small number of entry ports

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 side hole with clean water immediately after use and dry fully before autoclaving. On an angled cannula, flush from both ends: any bend in a lumen is where residue settles first, and a partly blocked shaft changes how the solution distributes on the next case.

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 the flow rate and length sets the reach. For large body areas such as the abdomen, flanks and thighs, the 2.5mm to 4.0mm diameters in 25cm to 35cm are the usual working range, because they fill a large area in fewer passes. The 1.8mm to 2.5mm range in 15cm to 25cm suits arms, the neck and smaller regions, where the angle earns the most because the surface curves sharply. The 1.0mm to 1.5mm diameters in 5cm to 12cm are for facial and submental infiltration. Match the fitting to the syringe, pump or handpiece already in your theater.

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 angled cannula used for?

It is used to deliver tumescent or wetting solution into subcutaneous tissue 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 keeps the bend oriented in the plane the surgeon chose.

What is the difference between an angled cannula and a straight cannula?

An angled cannula has a bend in the shaft, so the working section travels at an angle to the hub; a straight cannula runs in one line. The angle lets the cannula follow a curved body surface and stay in the subcutaneous plane without the surgeon twisting the wrist. A straight cannula is simpler to clean and store.

Is this cannula autoclavable?

Yes. The instrument is fully reusable and can be steam autoclaved at 134°C. Flush the lumen and every side hole with clean water immediately after use, remove all residue before sterilization, and dry completely. Flush from both ends so nothing is left sitting in the bend, where residue collects first.

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, bend angles and hole 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.
