Bayonet Microaire Cannula

Bayonet Microaire Cannula

The Bayonet Microaire Cannula is manufactured from surgical-grade German stainless steel with a high-polish mirror finish on both the external shaft wall and the internal aspiration bore. Its working zone carries approximately 10 small circular ports in a staggered bilateral arrangement — each port measuring 1.5 to 2.0 mm in diameter — alternating between two lateral rows so each port sits axially between two opposite ports. A polymer composite MicroAire PAL-compatible power hub locks directly onto the MicroAire PAL-650 handpiece with a vibration-stable, non-slip fit. The tip is a closed atraumatic dome — blunt and fully rounded — for safe tissue tunneling without laceration. Available shaft diameters run from 3.0 mm to 4.0 mm, with working lengths of 20 cm and 30 cm.

The staggered port layout alternates suction between both shaft sides on each reciprocating stroke, preventing concentrated negative pressure on any single tissue plane. The MicroAire PAL-650 drives the cannula at up to 4,500 reciprocating strokes per minute with a 2.4 mm stroke amplitude, substantially reducing surgeon push-pull effort across extended procedures. The mirror-polished bore keeps aspiration flow consistent across all staggered ports without pressure imbalance at any axial point. This instrument is fully autoclavable and rated for up to 20 reprocessing cycles per MicroAire IFU guidelines.

Surgeons use the Bayonet Microaire Cannula in power-assisted liposuction procedures targeting medium to large body zones — abdomen, flanks, inner and outer thighs, arms, back, and knees — where the staggered bilateral port geometry produces a smoother, more even fat removal profile than symmetrical bilateral layouts. Its alternating suction geometry is particularly valuable in contour revision cases where surface regularity across adjacent tissue planes is the primary operative goal.

For surgeons running multi-case body contouring lists who need power-assisted instruments that perform without variation, Lipokey supplies this cannula with German stainless steel shaft construction and MicroAire-compatible hub tolerances that hold up from first use to the twentieth sterilization cycle.

How does the Bayonet staggered port pattern perform differently under power-assisted reciprocation compared to manual suction-assisted liposuction?
Under manual SAL, the staggered port effect is subtle since suction is continuous and the cannula movement is surgeon-controlled. Under PAL reciprocation at 4,500 strokes per minute, the alternating lateral ports engage tissue on both the forward and return strokes in an offset sequence — effectively distributing fat disruption and aspiration across a wider tissue arc per stroke cycle than a symmetrical bilateral pattern achieves at the same stroke speed.
