Threaded retaining rings are widely adopted in the mechanical structures of endoscopes to secure lens assemblies, spacer tubes and various components. At the factory, these threads are coated with adhesive for reinforcement, preventing loosening caused by vibration, thermal expansion and contraction during clinical use and sterilization cycles. For this reason, a specialized wrench set is required to disassemble these adhesive-locked threaded structures during maintenance.
- Full range of compatible sizes.
Covers standard component dimensions for commonly used clinical endoscopes, including laparoscopes, arthroscopes, sinuscopes and video endoscopes. A single set meets most endoscope disassembly requirements.
- Preserves endoscope exterior integrity.
Contact surfaces between the wrench and retaining rings are precision-machined to perfectly engage with the notches or bayonet slots on retaining rings. This eliminates slipping, surface scratches and component deformation during unscrewing, fully protecting the original appearance of the endoscope shaft.
- Controlled torque for tightening and loosening.
Cured adhesive inside threads requires a specific initial torque for disassembly; however, excessive force may crack retaining rings or strip threads. The specialized wrench set features optimized lever length and force application angles in its structural design. It allows technicians to perform disassembly and assembly with controllable force, while delivering specified tightening torque during reinstallation-achieving secure connections without under-tightening or over-tightening.
Advantages
Compared with generic thin-blade wrenches available on the market, our company has upgraded the bayonet arc profile and sheet metal hardness to balance ductility and wear resistance, resisting bending and deformation after prolonged service. All parts undergo burr-free precision finishing to prevent metal debris from contaminating the sealed chambers of endoscopes, complying with cleanliness standards for medical device maintenance. This significantly cuts the scrap rate of precision endoscope shafts during repair operations.
