Optical Properties and Medical Applications of Sapphire Surgical Tools

Sapphire (chemical composition: aluminum oxide, Al₂O₃) is an ideal material in medical instruments due to its excellent optical transparency, high hardness, high-temperature resistance, and corrosion resistance.

Sapphire Optical Properties

Sapphire exhibits extremely high transmittance in the ultraviolet to near-infrared spectrum, ensuring that medical devices provide clear and bright images under various lighting conditions.

Sapphire Application Areas

Endoscope Lenses

Sapphire endoscope lenses are widely used in medical diagnostics and minimally invasive surgeries due to their high transparency and durability.

Laser Surgical Blades

Sapphire blades are used in ophthalmic surgeries to cut the cornea, reducing tissue damage and promoting rapid postoperative healing.

Fiber Optic Probes

Sapphire ball lenses are used in common-path optical coherence tomography (CP-OCT) fiber optic probes to provide high-resolution ocular imaging.

In cataract surgeries, using sapphire blades to cut the cornea has been shown to result in higher incision quality, lower postoperative complication rates, and faster patient recovery.
