Sub Tenon Cannula, Angled, Tri Port, 21ga, 22mm

This 21ga sub‑Tenon cannula features an angled shaft and tri‑port distal tip on a 22mm working length, distributing anesthetic evenly across the posterior sub‑Tenon space. The angle aids approach to the posterior pocket through a conjunctival window, and the tri‑port pattern diffuses flow rather than jetting it from a single aperture. The 21ga lumen balances delivery with controlled placement.
