Finally, the limitations of laser processing at present are summarized, and the application and development of laser micromachining technology in the field of medical equipment in the future are prospected. Although laser microprocessing technology can micro-process a new generation of implantable medical devices with extremely fine structure, making the commercial use of the next generation of implantable medical devices feasible, the development of laser micro-processing technology in the biomedical field is not mature enough, the production efficiency is low, and the work stability needs to be improved. For the laser micromachining process, a complete set of theories has not yet been formed to explain the physical nature of the interaction between the laser and material under the extreme conditions of ultra-fast, ultra-short, and ultra-strong, nor can the impact of laser micromachining on the material structure and physical and chemical properties be well evaluated. The next work still needs a lot of basic and regular research. At the same time, according to the characteristics of laser micromachining and the properties of the processed materials, it is also necessary to develop simulation analysis software to simulate the micromachining process and optimize the parameters of the laser micromachining process.

Laser microfabrication has the characteristics of ultra fast, ultra precision, etc. It has unique advantages in the field of medical equipment by contrast with traditional processing technology. Especially, it plays an irreplaceable role in the surface processing of biological materials to improve the biocompatibility of materials. The latest application of laser microfabrication in the field of medical equipment manufacturing and processing in recent years is reviewed. The structure and surface manufacturing of vascular stents and bone stents, and the surface modification of biomaterials and antibacterial treatment are emphatically introduced. Finally, the limitations of the current laser micromachining technology are discussed, and the application and development of laser micromachining technology in medical equipment in the future are prospected.
