Bayonet Specific Luer Lock Cannula

Bayonet Specific Luer Lock Cannula

The Bayonet Specific Luer Lock Cannula combines a straight surgical-grade German stainless steel shaft with a lightweight aluminium luer lock hub at the proximal end. Along the active working zone, approximately 10 small circular ports sit in a staggered bilateral arrangement — alternating between two lateral rows so that each port on one side sits axially between two ports on the opposite side. Each port measures approximately 1.5 to 2.0 mm in diameter, keeping individual openings compact enough to deliver controlled, distributed suction without concentrating negative pressure at any single point along the shaft. The tip is a closed atraumatic dome — blunt and fully rounded — allowing the cannula to move through subcutaneous tissue planes without cutting fibrous bands or disrupting vascular structures. Available shaft diameters run from 2.0 mm to 4.0 mm, with working lengths of 15 cm and 20 cm to suit different treatment zones and patient anatomy.

The aluminium luer lock hub keeps the total instrument weight low, significantly reducing hand fatigue during extended syringe-assisted sessions. The threaded luer lock interface meets ISO standard dimensions, forming a pressure-stable, leak-proof connection with any compatible luer lock syringe or luer lock connecting handle — no adapters, no tools, and no fluid bypass under active injection or aspiration pressure. The mirror-polished internal bore keeps flow resistance uniformly low across all staggered ports, distributing tumescent solution or aspiration force evenly along the full working zone. The stainless steel shaft is fully autoclavable and corrosion-resistant, retaining its staggered port geometry, surface finish, and dimensional accuracy through repeated sterilization cycles at standard 134°C autoclaving temperatures without oxidation at the hub-shaft junction.

Plastic surgeons and aesthetic practitioners use the Bayonet Specific Luer Lock Cannula in tumescent solution infiltration procedures prior to liposuction, where the staggered bilateral port layout distributes anaesthetic-vasoconstrictor fluid across both sides of the tissue tunnel on each pass — reducing the number of passes needed to fully saturate a treatment zone. Its 2.0 mm diameter variant is also used in small-zone fat harvesting procedures for facial fat grafting, including cheek augmentation, temple hollowing correction, and periorbital restoration, where the narrow shaft and luer lock syringe connection allow low-pressure, manual Coleman-technique aspiration with direct volume control. The wider 4.0 mm variants handle medium-volume infiltration in larger body zones including the abdomen, flanks, and thighs.

Lipokey delivers this cannula with consistent German stainless steel shaft construction, stable aluminium hub bonding, and reliable luer lock thread tolerances that hold up across every autoclave cycle and every procedure. Their manufacturing standards remove the guesswork from instrument selection and let surgeons focus entirely on the operative task.

Are luer lock syringes male or female?
As a way to mitigate accidental separation, Luer-lock fittings were developed and are comprised of a male taper with an associated threaded “skirt” and a female taper having flanges to engage the threads called “lugs”
