This 8 mm Endowrist Mega needle driver is an advanced robotic instrument custom-machined for heavy-duty needle handling and smooth manual suturing controls using the da Vinci Si system. Its robust multi-jointed wrist linkage mimics natural human wrist mechanics, empowering the robotic surgeon to clamp and drive heavy needles through thick fascia with absolute directional control. Supplied completely sterile, its textured tungsten carbide jaw inserts maximize needle hold parameters to prevent accidental slippage bugs.
