Why Is Steel Chosen As The Material for The Protective Sheath of The Endoscope Camera Module?

The use of steel for the protective sheath of the endoscope camera module is primarily based on its high-strength protection and environmental adaptability. Steel (such as stainless steel or titanium alloy) offers excellent resistance to pressure, impact, and abrasion, effectively safeguarding the internal precision optical components in narrow spaces or harsh working conditions. It can also withstand high temperatures, corrosive liquids, and repeated sterilization, meeting the stringent requirements of medical and industrial applications.

In addition, the biocompatibility and electromagnetic shielding properties of steel make it an ideal choice for medical examinations. Its surface is easy to clean and disinfect, complying with medical-grade hygiene standards. The thin-walled design enables ultra-slim sizing (e.g., φ1.8mm probe), balancing protection and operational flexibility. Overall, its performance far exceeds that of engineering plastics or composite materials.
