This application discloses an optical fiber conduit and a laser ablation device. By setting the input end face of the optical fiber module as an inclined plane, different laser beams emitted from the laser module are refracted into the optical fiber body from different positions on the input end face. Therefore, different laser beams undergo multiple total internal reflections at different positions within the optical fiber body, and ultimately exit from the output end along the axial direction inclined to the optical fiber body, forming annular light spots. Therefore, compared to existing technologies that require a conical structure at the output end to achieve an annular light spot, this application achieves an annular light spot simply by setting the input end as an inclined plane, eliminating the need for complex conical and protective structures at the output end. This simplifies the processing steps at the output end, controls costs, and maintains the same fiber diameter between the output end and the optical fiber body, allowing the optical fiber conduit to meet the needs of smaller diameter vein laser closure surgeries.

This application discloses an optical fiber catheter and a laser ablation device. In the optical fiber catheter of this application, the input end face of the optical fiber module is set as an inclined plane relative to the radial direction of the optical fiber body, and a light-emitting unit is formed circumferentially near the output end of the optical fiber body. This allows a portion of the laser light to be emitted obliquely outward from the light-emitting unit, forming a first annular spot, and another portion of the laser light to be emitted from the output end along the axial direction inclined to the optical fiber body, forming a second annular spot. This effectively disperses the output laser energy while simultaneously allowing for pre-contraction of the vascular area requiring closure using the first annular spot, followed by closure using the second annular spot. This results in gentler laser energy for ablation and closure of the blood vessel, effectively increasing the treatment area, thereby improving the ablation closure rate and surgical success rate, and reducing the risk of patients requiring secondary treatment.
