Olympus Ureteroscope WA29040A Repair Case

Device Introduction

The Olympus WA29040A ureteroscope is a high-precision endoscope widely used in urological surgeries. It features a 12° viewing angle design, making it suitable for ureteral examinations and minimally invasive procedures. Its core components include the working tube assembly, objective lens group, image bundle, light guide bundle, and optical system, which require regular maintenance to ensure clear imaging and operational safety.

Repair and Inspection Findings

Blurred Imaging: Both ocular observation and electronic imaging tests revealed unclear images with fog-like interference.

Objective Lens Wear: Microscopic inspection showed scratches on the objective lens surface, affecting light transmittance.

Bent Tube: The outer tube exhibited significant bending deformation, obstructing the instrument channel.

Repair Plan

Replace the Working Tube Assembly: Remove the deformed outer tube and replace it with an original factory-matched tube to restore instrument channel patency.

Replace the Objective Lens Group: Install a new objective lens assembly to eliminate optical distortion.

Replace the Image Bundle: Use a high-precision fiber optic image bundle to ensure uninterrupted image transmission.

Replace the Light Guide Bundle: Upgrade the light guide fibers to improve light source conduction efficiency.

Clean and Adjust the Ocular Lens Group: Disassemble the ocular lens group to remove internal stains and recalibrate the focal length.

Calibrate Imaging: Adjust the optical system using test targets until the image is sharp and free of deviation.

Thoroughly Clean the Optical System: Use professional cleaning agents to treat internal lenses and channels.
