With the continuous development of science and technology, more and more emerging technologies appear and develop the medical value of the technology, and the medical optical fiber is one of the technologies. The laser resonant cavity of the medical optical fiber is not provided with an optical lens, and the laser optical fiber has the advantages of no adjustment, no maintenance and high stability, which is incomparable with the traditional laser. In addition, the medical laser fiber has high electro-optic efficiency, for example, the comprehensive electro-optic efficiency of the medical laser fiber is up to more than 20%, the power consumption during working is greatly saved, the operation cost is saved, and the medical laser fiber has high power.
Meanwhile, the laser medical optical fiber is a medical optical fiber specially used for transmitting the ultra-high-power holmium laser, and the laser optical fiber is mainly used for treating kidney stones, prostatitis and fat cutting.

The structure of the optical fiber comprises an optical fiber core, a coating layer, a glue adding area and a shell layer, wherein the optical fiber core is coated by the coating layer, and the light can be totally reflected in the coating layer, so that the light can be continuously reflected in the optical fiber core in front and is transmitted from one end of the optical fiber to the other end of the optical fiber; the cladding layer is fixed in the shell layer by the glue filling area, and the shell layer is usually used for protecting the optical fiber core so as to prevent the optical fiber core from being damaged due to bending and breaking.
At present, a commonly used method for detecting a breakpoint of an optical fiber is to arrange two workers at two ends of the optical fiber respectively, wherein the worker at one end connects a light pen serving as an optical fiber detector to two connectors corresponding to an optical fiber jumper, then turns on a light power switch, and the worker at the other end observes whether red light appears or not, and if the red light appears, the judgment is that the optical fiber does not have a breakpoint. When the optical fiber has a breakpoint, the optical fiber is placed in an environment with poor light, and the position of the breakpoint is determined through manual observation.
Although the method can detect whether the optical fiber has breakpoints, the optical fiber needs to be detected one by one, and the working efficiency is low.
