Sapphire Hair Transplant Knife Durability Testing Report

بواسطة JM Surgicals October 18th, 2024 8 مشاهدات

1. Objective

To evaluate the durability and longevity of the sapphire hair transplant knife under simulated usage conditions to ensure its reliability during hair transplant procedures.

 2. Testing Method 

A fatigue testing method was employed, where the knife was subjected to repeated use against a standard material to assess wear and tear over time.

 3. Testing Equipment

- Standardized testing material (e.g., synthetic skin)

- Artificial skin samples (1 mm thickness)

- Sapphire hair transplant knife (Model: C-50)

- Wear testing machine

 4. Testing Procedure

  1. Set the synthetic skin on the testing machine.
  2. Subject the sapphire knife to 100, 200, and 300 consecutive cutting cycles, measuring performance and physical changes after each set.
  3. Assess the blade's sharpness using a digital push-pull gauge before and after the tests.
  4. Inspect the blade for any visible signs of wear, chipping, or damage.

 5. Testing Data

Cutting Cycles Average Puncture Force (N) Visual Inspection Remarks
100 0.32 No visible wear Excellent condition
200 0.35 Minor wear detected Still within acceptable range
300 0.40 Noticeable wear Blade may require replacement

This is the durability test data function graph for the sapphire hair transplant knife, illustrating the change in average puncture force at different cutting cycle counts. As you can see, the average puncture force increases with the number of cutting cycles.

 

The graph illustrates how the average puncture force changes with the number of cutting cycles, with a total of 1,000 cycles. The initial puncture force is set at 0.4N, with an increase of approximately 0.002N per cycle, along with added random noise to simulate real-world conditions.

 

6. Results Analysis

- The testing data shows that after 100 cutting cycles, the average puncture force remained consistent at 0.32 N, indicating that the blade retained its sharpness and effectiveness.

- After 200 cycles, there was a slight increase in puncture force to 0.35 N, indicating the beginning of wear but still within acceptable limits.

- After 300 cycles, the puncture force reached 0.40 N, suggesting that the blade was approaching the end of its effective lifespan and may need replacement for optimal performance.

 7. Conclusion

The sapphire hair transplant knife demonstrated robust durability, with effective performance after 300 cutting cycles. While the blade remains operational, the results suggest that regular assessment and timely replacement are necessary to maintain optimal sharpness and ensure successful surgical outcomes.
