Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a thoracic surgery operation drag hook, including mount pad 1, drag hook body 2, the up end fixed mounting of mount pad 1 has bracing piece 4, the up end fixed mounting of bracing piece 4 has telescopic link 3, be convenient for adjust the length of operation drag hook, the flexible end of telescopic link 3 is rotated and is connected with concave frame 5, the angle modulation of drag hook body 2 has been realized, the inside of concave frame 5 is provided with threaded rod 8 and gag lever post 9, the screw thread of threaded rod 8 sets up to two-way screw thread, the rotation of having guaranteed threaded rod 8 drives two movable blocks 7 and is relative motion, drag hook body 2 is connected with threaded rod 8 and gag lever post 9 through movable block 7.
Specifically, as shown in fig. 2, the moving block 7 is connected with the threaded rod 8 in a screwing mode, the moving block 7 is connected with the limiting rod 9 in a sliding mode, it is guaranteed that the threaded rod 8 rotates to drive the moving block 7 to move, and meanwhile the limiting rod 9 can prevent the moving block 7 from deviating in an angle mode in the moving process.
Specifically, as shown in fig. 3, a connecting hole 10 is formed in the end portion of the retractor body 2, a hollow cavity 6 is formed in the moving block 7, connecting pins 11 are arranged on two sides of the upper end and the lower end of the moving block 7, and the end portion of each connecting pin 11 penetrates through the hollow cavity 6 to be connected with the connecting hole 10 in an inserting mode, so that the retractor body 2 and the moving block 7 form a detachable connecting structure.
