Details
1.Objective

To evaluate the sharpness of the sapphire hair transplant knife to ensure its effectiveness and safety during hair transplant procedures.

 2.Testing Method

A standardized puncture force testing method was employed using a digital push-pull gauge to measure the force required for the knife blade to penetrate a specific material (e.g., artificial skin).

 3.Testing Equipment

Digital push-pull gauge

Artificial skin samples (1 mm thickness)

Sapphire hair transplant knife (Model: C-50)

 4.Testing Procedure

     1.Fix the artificial skin on the testing platform.
     2.Position the sapphire hair transplant knife vertically against the skin sample.
     3.Gradually apply force until the blade penetrates the material, recording the maximum force (N) required.
     4.Repeat the test six times and calculate the average value.

 5.Testing Data

Test Number Maximum Puncture Force (N) Remarks
1 0.34 First test
2 0.32 Second test
3 0.31 Third test
4 0.32 Fourth test
5 0.30 Fifth test
6 0.33 Sixth test
Average 0.32

6.Results Analysis

The testing data indicates that the sapphire hair transplant knife has an average maximum puncture force of 0.32 N when penetrating the artificial skin sample. This value is below the industry standard (typically around 0.4 N), indicating that the knife exhibits excellent sharpness.

The ultra-fine blade and high-precision cutting process contribute to minimizing tissue damage, enhancing surgical accuracy, and improving patient recovery times.

 7.Conclusion

The sapphire hair transplant knife has passed the sharpness testing, demonstrating that its sharpness meets or exceeds industry standards, making it suitable for hair transplant surgeries and effectively improving surgical outcomes and patient satisfaction.
