Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber components, in particular to a medical laser optical fiber component. Background Art

[0002] When using existing medical fiber optic components for surgery, once the light-emitting end face of the optical fiber contacts soft tissue or is adsorbed by suspended tissue fragments, the laser will be absorbed by these organic substances adhered to the light-emitting end of the optical fiber. If the wavelength of the laser transmitted by the optical fiber is less than 500nm, these adhered human organic substances will have a strong absorption and scattering effect on this high-photon energy laser, thereby causing the laser energy to accumulate at the light-emitting end of the optical fiber and generate local high temperature. When the laser power exceeds 100W, this strong absorption will quickly heat the light-emitting end face of the optical fiber, causing the surgical optical fiber to be burned in an avalanche-like manner from the light-emitting end face to the optical fiber body, making it impossible for doctors to perform surgery normally.
