摘要: The objective of the present research was to investigate thermal injury in brain after minimally invasive electrosurgery using instruments with copper-doped diamond-like carbon (DLC-Cu) surface coating. morphologies DLC-Cu thin films were characterized scanning electron microscopy and atomic force microscopy. Three-dimensional models reconstructed magnetic resonance imaging simulate electrosurgical operation. In adult rats, a monopolar instrument coated film used generate lesions brain. Animals sacrificed for evaluations on postoperative days 0, 2, 7, 28. Data indicated that temperature decreased significantly when nanostructure continued decrease increasing thickness. On other hand, DLC-Cu-treated device created relatively small area lateral effect tissues. These results minimized excessive uniformly distributed Taken together, our study suggest copper electrode substrates is an effective means improving performance instruments.
