The application of high-power lasers in surgical clinical treatment, leveraging their high energy density and controllable wavelength, enables high-precision cutting, vaporization, and coagulation of diseased tissue. Their transient thermal effect can seal microvessels and reduce exudation, significantly reducing intraoperative bleeding. Simultaneously, thermal disinfection reduces the bacterial load in the surgical area and lowers the incidence of infection. The selective photothermal effect of lasers maximizes the protection of surrounding healthy tissue, reduces postoperative inflammation and pain, and promotes tissue repair and functional recovery, demonstrating significant clinical value in minimally invasive surgery, tumor resection, and plastic surgery and reconstruction.
