AI Technical Summary

Technical Problem

The protection device of existing medical laser fibers is fixed to the fiber main body, which leads to the need to replace the entire fiber when the protection device ages, which increases costs and is inconvenient to change the focus position of the laser.

Method used

A corrosion-resistant laser fiber including a body, an outer tube, a coating, a protective tube, a clamp, a thread, a through hole, a sealing plug and a gasket are designed. The outer tube consists of paint and protective tubes, fixed by clamps and threads, through holes and sealing plugs for sealing, and cogs, lenses, covers, springs and presses are used to change the focus position of the laser.

Benefits of technology

It is realized that only the outer tube is replaced when the external protection device is aging, which reduces the cost of use, and changes the focus position of the laser by selecting different lenses, improving the adaptability and sealing of the device.

Abstract

The utility model discloses a corrosion-resistant laser optical fiber, which relates to the technical field of optical fibers and comprises a main body, an outer tube is arranged on the periphery of the main body, the outer tube is composed of paint and a protective tube, the paint is a parylene coating, a hoop is arranged on the periphery of one end of the outer tube, threads are arranged on the other side of the hoop through the outer tube, and the protective tube is arranged on the outer tube. And eight through holes are formed in the side face of the end, located on the threads, of the outer pipe, the through holes are evenly distributed around the circle center of the outer pipe, sealing plugs are slidably arranged in the through holes, and the number and the position of the sealing plugs are consistent with those of the through holes. Compared with an existing common laser optical fiber, the corrosion-resistant laser optical fiber has the advantages that the outer tube needs to be sleeved outside the main body before use, the hoop is fastened and the outer tube is fixed on the outer side of the main body when the corrosion-resistant laser optical fiber is in place, and then the sealing plug is inserted into the through hole, so that the main body can be isolated from the outside, and the corrosion of the main body can be avoided; and after the protection device of the external outer pipe is aged, the protection device can be directly replaced, so that the use cost can be further reduced.
