[0015] The working principle and beneficial effects of the present utility model are as follows:

[0016] 1. In the present utility model, through the provided movable sleeve, pull rod and slider, when the laser optical fiber needs to be used, manually push the pull rod to the left to drive the movable sleeve to move. By utilizing the limiting effect of the slider and the spring on the movable sleeve, the movable sleeve slides along the track of the movable groove on the inner wall of the outer sleeve, compressing the spring installed in the inner groove. During the sliding process, since the movable sleeve is hingedly connected to the pin block through a connecting rod, and one end of the pin block is movably connected to the outer wall of the connecting block through a bearing, the connecting rod drives the pin block to contract inward. At this time, the pin block is inserted into the inner wall of the connecting assembly. Release the pull rod, and the elastic force generated by the deformation of the spring causes the movable sleeve to reset and slide to the right on the outer wall of the connecting block. During the sliding process, the connecting rod will contact the pin block, causing one end of it to expand outward to form a conical structure, so that the expanded side of the pin block fits the inner wall of the connecting assembly and simultaneously contacts the inner wall of the inner card slot, connecting the optical fiber main body to the laser therapy machine. This structure is convenient for connecting to the laser therapy machine and improves the usage effect of medical staff.

[0017] 2. In the present utility model, through the provided laser therapy machine, optical fiber main body and conical port, start the laser therapy machine, pull out the quartz glass sleeve, so that the conical port provided at the front end of the optical fiber main body is exposed. During use, the optical fiber is protected by the protective layer and the flexible protective layer to prevent bacterial infection. At the same time, the flexible material of the flexible protective layer gives the front end of the optical fiber main body a certain flexibility, so as to be flexibly used in complex surgical operations, and at the same time has good durability to ensure long-term stable performance. At the same time, when passing through the conical port, the light spot output by the optical fiber main body can be annular, which can effectively reduce the size of the surgical wound, meet the needs of different body parts, and relieve surgical pain. When the optical fiber main body needs to be replaced, the tail sleeve can be rotated. Through the optical fiber connecting screw rod provided on the tail sleeve and the internal thread provided on the inner wall of the optical fiber connecting threaded sleeve, the entire optical fiber main body can be removed for replacement. This structure can effectively reduce the surgical wound, the optical fiber is more flexible during use, and at the same time it is convenient to disassemble and replace the optical fiber, improving the clinical experience of patients.

During use, the optical fiber is protected by the protective layer 5 and the flexible protective layer 6 to prevent bacterial infection. At the same time, the flexible material of the flexible protective layer 6 gives the front end of the optical fiber main body 9 a certain flexibility, so as to be flexibly used in complex surgical operations, and at the same time has good durability to ensure long-term stable performance. At the same time, when passing through the conical port 19, the light spot output by the optical fiber main body 9 can be annular, which can effectively reduce the size of the surgical wound, meet the needs of different body parts, and relieve surgical pain. When the optical fiber main body 9 needs to be replaced, the tail sleeve 4 can be rotated, and the optical fiber main body 9 can be removed as a whole for replacement through the optical fiber connecting screw rod 10 provided on the tail sleeve 4 and the internal thread provided on the inner wall of the optical fiber connecting threaded sleeve 3.

When in use, the optical fiber is protected by the protective layer 5 and the flexible protective layer 6 to prevent bacterial infection. At the same time, the flexible material of the flexible protective layer 6 gives the front end of the optical fiber main body 9 a certain flexibility, so as to be flexibly used in complex surgical operations, and at the same time has good durability to ensure long-term stable performance. At the same time, when passing through the conical port 19, the light spot output by the optical fiber main body 9 can be annular, which can effectively reduce the size of the surgical wound, meet the needs of different body parts, and reduce surgical pain.
