Designed for precise nerve localization during peripheral nerve block procedures, Avanos Medical PROBloc* II Insulated Regional Block Needles integrate advanced electrical nerve stimulation with targeted local anesthetic delivery. Featuring durable sleeve insulation that leaves only the active tip exposed, these needles concentrate electrical current at the distal point to ensure accurate nerve proximity identification prior to injection. Packaged with attached flexible tubing injection sets and extension cables, they provide clinicians with optimal tactile control, high-visibility depth markings, and smooth tissue penetration for single-injection regional anesthesia across various anatomical sites.
