Background
The existing laser therapeutic apparatus for medical operation generally depends on an optical fiber line to transmit laser, the optical fiber line is fixed on a therapeutic hand tool, the optical fiber line needs to be taken out of the therapeutic hand tool after each treatment, a section of optical fiber used for operation treatment is cut by an optical fiber cutter and then discarded, the section of optical fiber is in direct contact with a patient, and the section of optical fiber needs to be cut and discarded in order to be sanitary and avoid causing cross infection; after the section of optical fiber is cut and discarded, the outer plastic sheath of the small section of optical fiber wire is stripped by an optical fiber stripper to expose the inner bare optical fiber, and finally the optical fiber wire is reinstalled into the treatment hand tool for the next treatment. This method requires a lot of time and effort to prepare the repetitive and cumbersome optical fiber line, is inefficient, and also involves a risk of cross-infection in the treatment process with a certain probability, and if the effect of the stripper is poor or not used properly, it is easy to cause that the plastic protective sheath cannot be stripped or the surface of the optical fiber line is scratched when stripping.
