Bayonet Tumescent Infiltration Cannula – Fixed Power Handle

The Bayonet Tumescent Infiltration Cannula with Fixed Power Handle is a blunt-tip cannula with a stepped offset shaft and the handle permanently attached, used to deliver tumescent or wetting solution before liposuction. Because handle and shaft are one piece, the bayonet offset holds its orientation exactly, there is no joint to loosen mid-case and no leak point in the fluid path. See the full Tumescent Bayonet Infiltration Cannulas range for other fittings.

Buyers also search for this instrument as a fixed handle bayonet cannula, a one-piece offset infiltrator, or an integrated handle tumescent cannula.

One-Piece Fixed Handle Bayonet Cannula in German Stainless Steel

A fixed handle removes the weakest point of a modular cannula. On a screw-fit or Luer-fit instrument the joint is where play develops, where solution leaks under pressure, and where residue collects. On a bayonet shaft there is a further gain: with no joint, the offset cannot rotate out of the position the surgeon set it in.

What the Bayonet Shape Does

A bayonet cannula has a stepped offset bend in the shaft between the hub and the working section. The offset moves the hub, the handle and the surgeon's hand sideways, out of the straight line running back from the entry site. That single change in geometry solves two problems at once.

First, sight lines. With a straight cannula the hand sits directly behind the entry point and blocks the view of the skin being filled. With the offset, the hand is out of that line and the surgeon can watch the entry site and the tissue turgor while infiltrating.

Second, angle of approach. The offset lets the working section be held closer to parallel with the skin while the hub stays clear of the body surface. The cannula stays in the subcutaneous plane instead of angling down into deeper tissue, which is exactly what an infiltration pass needs. The same clearance helps when working under a retracted flap or in a confined area where a straight hub would foul the surrounding tissue.

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

• ✔ Handle and shaft in one piece — the bayonet offset cannot rotate out of position
• ✔ No joint to loosen or leak under pump pressure
• ✔ Simpler cleaning — no thread or hub cavity to brush out
• ✔ Stepped bayonet offset keeps the hand clear of the entry site sight line
• ✔ Working section can be held closer to parallel with the skin surface
• ✔ 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
• ✔ Custom diameters, lengths and hole patterns available on request

Clinical Applications

• Tumescent infiltration before body liposuction of the abdomen, flanks, back and thighs
• Wetting solution delivery before power-assisted and syringe liposuction
• Arm, neck and submental infiltration with the shorter, smaller-diameter sizes
• Infiltration under a retracted flap or in confined areas where a straight hub would foul

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 a bayonet cannula, pay attention to the offset bend during cleaning: any bend in a lumen is where residue settles first, so flush from both ends until the water runs clear.

How to Choose

A fixed handle serves one shaft only, so it suits sizes you use case after case; if you rotate through many diameters, a detachable fitting costs less per size. 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. The 1.0mm to 1.5mm diameters in 5cm to 12cm are for facial and submental infiltration, where thin tissue needs a small-diameter cannula. 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 fixed handle bayonet infiltration cannula used for?

It is used to deliver tumescent or wetting solution into subcutaneous tissue before liposuction, with the handle permanently joined to the offset shaft. Surgeons choose it for routine sizes where they want maximum rigidity, a bayonet that never rotates out of position, and the simplest cleaning after the case.

What is the difference between a bayonet cannula and a straight cannula?

A bayonet cannula has a stepped offset in the shaft; a straight cannula does not. The offset moves the hub and the surgeon's hand out of the line of sight to the entry site, and lets the working section stay closer to parallel with the skin. A straight cannula is simpler to clean and store, but the hand blocks the view.

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 offset 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. Tell us the diameter and length you want to evaluate and we will confirm what can be sent. Handling a sample is the only reliable way to judge how the offset and handle balance together.

Can I order a custom size?

Yes. Custom diameters, working lengths, 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.
