Stryker Arthroscopy Repair Case

Detailed description of the fault content:

1. Blurred image: After preliminary diagnosis, it was found that the endoscope imaging system was abnormal, resulting in insufficient output image clarity and unable to meet clinical observation needs.

2. Broken objective lens: During the inspection, it was found that the objective lens assembly at the front end of the endoscope was cracked and partially broken, affecting the quality of optical transmission.

3. Broken rod lens: Further inspection confirmed that the rod lens inside the endoscope was also damaged, which directly affected the focus of light and the clarity of the image.

Detailed maintenance plan:

1. Replace the objective lens: Completely replace the damaged objective lens assembly to ensure that the new objective lens meets the optical standards and performance requirements specified by the manufacturer.

2. Replace the rod lens: Replace the damaged rod lens and select a high-quality lens that matches the original specifications to restore the optical performance of the endoscope.

3. Proofread the image: After replacing the key optical endoscope components, perform fine image calibration and adjust to the optimal imaging state to ensure that the image is clear and distortion-free.

4. Endoscope anti-vibration and impact performance test: After the maintenance is completed, the endoscope is subjected to strict anti-vibration and impact tests to verify its stability and durability under extreme conditions.

5. Endoscope sealing performance test: To ensure that the endoscope can maintain good working condition in various environments, a comprehensive sealing test is carried out to prevent moisture and dust from intruding.

6. Endoscope hot and cold shock performance test: Simulating the temperature changes in actual use, the endoscope is subjected to hot and cold shock tests to ensure that it can work normally at different temperatures without performance degradation.
