Abstract

The invention relates to the technical field of medical instruments, in particular to an implanted instrument surface and a manufacturing method thereof. The manufacturing method comprises the following steps that S1, a metal instrument surface is polished; S2, femtosecond laser is adopted to etch the instrument surface polished in the S1, a microstructure surface is etched, and the microstructure surface is provided with microstructures of at least two sizes; S3, ultrasonic cleaning is conducted on the surface of the microstructure prepared in the S2 through absolute ethyl alcohol, and then the surface of the microstructure is cleaned through deionized water; and S4, hydroxylation treatment is conducted on the surface of the microstructure cleaned in the S3, then the surface of the microstructure is dried, and the surface of the implanted instrument is obtained. By means of the manufacturing method, the super-hydrophobic and self-cleaning antibacterial surface can be manufactured, and the surface of the implanted instrument has excellent super-hydrophobicity, antibacterial performance, self-cleaning performance and biocompatibility.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to an implanted device surface and a manufacturing method thereof. Background technique

[0002] After the implanted device of modern medicine is implanted into the human body, the surface of the implanted device will come into contact with body fluid tissue, and then adhere to the tissue, resulting in contamination of the implanted device or infection of human tissue, and generation of thrombus, which is harmful to the implanted device and human body. There are serious dangers.

[0003] At present, etching microstructures on the surface of implanted devices can isolate corrosive liquids to improve the biocompatibility of implanted devices. However, the methods for preparing microstructured surfaces in the prior art are template method, coating method, etching method and laser method. Although these methods can prepare microstructures, they are affected by method limitation...
