Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described with reference to the accompanying drawings and specific embodiments, which are not intended to limit the present invention.
Example 1
A thoracic surgery retractor is specifically shown in figures 1 and 3 and comprises a body 1, wherein the body 1 is of a hollow cylindrical structure, a through hole is formed in one end of the body 1, a pull rod 2 penetrates through the through hole, a retractor 3 is screwed at one end, far away from the body 1, of the pull rod 2, and the retractor 3 connected in a screwed mode can be detached, cleaned and disinfected after use;
a tooth-shaped through groove 30 is formed in the periphery of the body 1, a pull block 4 is fixedly arranged at one end, close to the body 1, of the pull rod 2, and the pull block 4 is in sliding connection with the tooth-shaped through groove 30;
the pulling block 4 comprises a fixed block 5 and pressing blocks 6, the fixed block 5 is provided with a through hole along the length direction of the fixed block 5, the pressing blocks 6 are movably connected with two ends in the through hole in a penetrating manner respectively, the adjacent ends of the two pressing blocks 6 are connected through a spring 7, and when the spring 7 is in a natural extension state, one of the pressing blocks 6 can be clamped in a tooth-shaped structure of the tooth-shaped through groove 30 to fix the pulling rod 2, so that the pulling hook 3 is fixed; the spring 7 is fixedly connected with the pressing blocks 6 through belt ring screws, a limiting plate 61 is fixedly arranged on one side, away from the spring 7, of each pressing block 6, and the limiting plate 61 is arranged to prevent the pressing blocks 6 from sliding out of the through holes;
