It is necessary to reduce the thermal damage in the adjacent tissues for clinical electrosurgical surgeries. Method: Cu-DLC films were characterized by scanning electron microscope (SEM) and transmission electron microscopy (TEM) to analyze the surface morphologies in this study. Bionic liver models were reconstructed using magnetic resonance image (MRI), and data analysis indicated that the temperature decreased significantly when using electrosurgical device with nanostructured Cu-DLC films, temperature also decreased with increasing film thicknesses. Results: Lesions were made on the liver of adult rats, and thermography revealed the surgical temperature in liver tissue from the Cu-DLC group was significantly lower than the untreated group. Moreover, Cu-DLC electrodes caused a relatively smaller area of injury area and lateral thermal injury, a smaller area of fibrotic tissue, and a faster process of wound healing than the untreated group. II Conclusion: Results indicated that the coated film reduced excessive temperature and transformed the temperature uniformly in the liver tissue.系所名稱：醫療器材產業碩士專班thesis
