ADDLER Autoclavable HD 4mm 0° Sinoscope with Sheath
The ADDLER Autoclavable HD 4mm 0° Sinoscope with Sheath is a high-definition rigid endoscopic system designed for precise visualization during diagnostic and operative nasal endoscopic procedures. Combining a 4mm 0° HD sinoscope with a precision-engineered endoscopic sheath, the system provides exceptional optical clarity, continuous irrigation, and enhanced surgical control for ENT specialists.
The 0° viewing direction offers a direct forward view, making it ideal for routine nasal examinations and functional endoscopic sinus surgery (FESS). Featuring advanced HD rod-lens optics, the sinoscope delivers outstanding image resolution, superior light transmission, and accurate color reproduction for detailed visualization of the nasal cavity and paranasal sinus anatomy. Manufactured from premium medical-grade stainless steel, both the scope and sheath are fully autoclavable, ensuring long-lasting durability and reliable performance through repeated sterilization cycles.
