Mizuho OSI Ultra Shoulder Positioner System | Beach Chair Model Assembly | Includes Mobile Storage and Transport Cart

The Mizuho OSI Ultra Shoulder Positioner is a professional-grade manual patient positioning system engineered for stable beach chair positioning during arthroscopic reconstructions, total shoulder joint arthroplasty, and upper extremity trauma repairs. It docks directly onto standard operating room side rails, providing a low-profile, radiolucent backrest that maintains obstruction-free access to the operative shoulder. Featuring integrated adjustable headrest wings and multi-axis articulation controls, this assembly enables precise adjustments to optimize anatomical visualization for the surgeon and airway access for the anesthesia team. The package includes a heavy-duty mobile storage cart to securely store the positioner and its side modules between surgical cases.
