Description

Technical Field

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

[0002] Fiber lasers, with their advantages of high electro-optical conversion efficiency, excellent output beam quality, easy thermal management, and stable operation, have been a hot topic of research in recent years. With the advancement of fiber fabrication technology, fiber lasers based on optical fibers have achieved significant progress in lowering thresholds, increasing oscillation wavelength range, and achieving wavelength tunability, becoming an emerging technology in the laser field. 2μm lasers, known as "eye-safe" lasers, hold broad potential in medical surgery, atmospheric monitoring, lidar, remote sensing, and other fields. Thulium-doped fiber lasers, a new type of high-power laser, utilize thulium-doped quartz fiber as a gain medium and operate at a wavelength of 2μm, well within the eye-safe wavelength range. With improvements in fiber design and fabrication, as well as advances in semiconductor laser pumping technology, 2μm thulium-doped fiber lasers have experienced rapid development. Thulium-doped fiber lasers offer long-wavelength laser oscillation at a wavelength of approximately 2μm, close to the absorption peak of water. They offer excellent tissue-cutting and blood-clotting properties and can be transmitted using conventional optical fibers, making them ideal surgical laser sources.

[0003] As shown in the application number 201811366688.X, the present invention discloses a laser fiber protective cover. When performing laser treatment, the protective cover is used to cover the target area, which can accurately treat the target area, improve the safety of the operation, make it safer and more reliable, and avoid high-power output laser and heat from damaging surrounding tissues. A temperature monitoring device is provided in the protective cover. By real-time and accurate monitoring of the temperature changes of the target tissue, combined with the relationship between various treatment parameters and the size, number and position of the target tissue, the output energy and pulse frequency of the semiconductor laser are controlled in real time to meet the application requirements of precise minimally invasive treatment. However, the external protective component of this laser fiber is not convenient for providing stability for treatment during treatment. This is mainly reflected in the following aspects: first, it is not convenient to avoid the deviation of the protective component; second, there is a large gap between the optical fiber and the protective component, which is not convenient for providing stability for treatment, and the optical fiber cannot be protected when it is not in use.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and a laser optical fiber with a protective component is proposed. Utility Model Content

Before treating the patient, the swivel 4 needs to be mounted on the upper end of the mounting base 1, and the position of the mounting base 1 is adjusted and pressed against the patient's skin, and then the swivel 4 is rotated to drive the middle part of the suction cup 3 to move upward through the top rod 2. In this way, the device can be fixed around the affected area through the suction cup 3, thereby avoiding deviation during treatment, thereby improving the stability of the device during operation and avoiding rework;

[0025] Furthermore, the rotating ring 4 controls the suction cups 3 and can control multiple suction cups 3 at the same time, and can also be fixed at any time.

[0026] like Figure 2 、 Figure 4-Figure 5As shown, the cross section of the slide groove 5 is T-shaped, and the slide groove 5 is slidably connected to the top rod 2 at the same time. The upper end of the mounting seat 1 is located on the inner side of the swivel 4 and is provided with a threaded groove 6, and the threaded groove 6 is engaged with the swivel 4. A mounting tube 7 is fixedly provided in the middle of the mounting seat 1, and the mounting tube 7 is arranged in a funnel shape. A shaft body 8 is fixedly provided around the mounting tube 7, and a torsion spring 9 is fixedly provided in the middle of the shaft body 8. A limiting plate 10 is provided on the outer side of the shaft body 8, and eight limiting plates 10 are evenly distributed around the center of the mounting tube 7. The other end of the torsion spring 9 is fixedly connected to the limiting plate 10, and a slot 11 is provided on one side of the torsion spring 9 through the limiting plate 10.

[0027] Furthermore, the spiral groove 15 can prevent the optical fiber from being bent at an excessively large angle, thereby causing damage to its internal components.

[0028] Furthermore, the material of the claw 19 needs to be tough so that it can pass over the mounting ring 14 and enter the slot 20 .

[0029] Working principle: When using the laser optical fiber with protective components, first, before treating the patient, the swivel 4 needs to be at the upper end of the mounting base 1, and the position of the mounting base 1 is adjusted and then pressed against the patient's skin. Then, the swivel 4 is rotated so that it drives the middle part of the suction cup 3 to move upward through the top rod 2. In this way, the device can be fixed around the affected area through the suction cup 3, thereby avoiding deviation during treatment, thereby improving the stability of the device during operation and avoiding rework; secondly, after the mounting base 1 is fixed, the optical fiber is installed into the mounting tube 7, and after adjusting the distance between the optical fiber and the skin, the limit plate 10 is pushed in until it is fixed by the limit plug 12. It can fix the optical fiber to prevent it from shaking inside the mounting tube 7, thereby improving the efficiency during treatment. When removing or replacing the optical fiber, the limit plug 12 is pulled upward, and then the limit plate 10 is ejected by the torsion spring 9, so that the interface begins to pull out the optical fiber. Finally, after the use of the optical fiber, two placement methods can be used. If the user is not skilled in operation, one end of the optical fiber can be placed on the fixing plate 16 on either side, and the optical fiber can be laid along the spiral groove 15. After the optical fiber is laid, the optical fiber in the fixing plate 16 is taken out and placed in the spiral groove 15, and finally the cover plate 17 is covered. This can prevent the optical fiber from being damaged when not in use. This is the working principle of the laser optical fiber with a protective component.
