[0015] The present invention has the following beneficial effects: (1) The present invention places a hook plate inside the wound, starts the electric telescopic rod, and drives the working plate to move. The two working plates move away from each other. The working plate drives the sliding frame to move. The sliding frame drives the hook plate to move. The two hook plates move away from each other, thereby opening the wound and facilitating the doctor to perform a surgical operation. When the working plate moves, the working plate drives the moving part to move. The moving part drives the vertical rod to move. The vertical rod is limited by the second slot. The vertical rod slides along the inner wall of the second slot and is limited by the limiting hole. The vertical rod drives the moving part to slide along the inner wall of the limiting hole, so that the two moving parts move away from each other, the moving part drives the connecting part to move, the connecting part drives the spring frame to move, and the spring frame drives the cross hook locking sleeve to move, so that the distances between multiple cross hook locking sleeves and the hook plates can be equidistant, so as to achieve uniform traction of blades of different lengths, avoid using multiple independent hooks for traction on larger blades, and improve the effect of stretching the wound. The outer wall of the cross hook locking sleeve is coated with disinfectant, which can prevent the wound from infection during the process of the cross hook locking sleeve stretching the wound.

[0016] (2) In the present invention, when the vertical rod moves, the vertical rod drives the gear to move. The gear drives the vertical rod to rotate along the inner wall of the moving part due to the limit of the toothed plate. The vertical rod drives the belt to rotate. The belt drives the cross rod to rotate. The cross rod drives the cross hook lock sleeve to rotate. The cross hook lock sleeve can come into contact with the inner wall of the wound during the rotation process, preventing the cross hook lock sleeve from coming into contact with the wound in a stopped state and generating friction, thereby causing damage to the inner wall of the wound. This improves the protective effect of the wound when it is stretched open.

[0017] (3) In the present invention, when the cross rod rotates, the cross rod drives the threaded rod to rotate, which is limited by the limit frame. During the rotation of the threaded rod, the threaded plate is driven to move downward along the outer wall of the limit frame, the threaded plate drives the round rod to move downward, and the round rod drives the arc plate to move downward. During the downward movement of the arc plate, it will contact the top of the cross hook lock sleeve, causing the cross hook lock sleeve to move downward along the outer wall of the cross rod, thereby expanding the range of the cross hook lock sleeve to lock, improving the stability of the wound opening, and improving the wound opening effect.

[0018] (4) According to the present invention, when the cross hook lock sleeve descends, the cross hook lock sleeve drives the rotating ring to descend, and the rotating ring drives the rotating bar to descend. The rotating bar drives the slider to slide along the inner wall of the slider. The slider drives the cross bar to move during the movement, and the cross bar drives the piston plate to move. The piston plate slides inside the liquid storage shell to squeeze the disinfectant inside the liquid storage shell, so that the disinfectant inside the liquid storage shell enters the inside of the connecting pipe, the disinfectant enters the inside of the elastic tube through the connecting pipe, and the disinfectant enters the inside of the spray shell through the elastic tube. The disinfectant is sprayed toward the outer wall of the cross hook lock sleeve through the spray shell to prevent the disinfectant applied during the rotation of the cross hook lock sleeve from being completely absorbed by the wound and unable to disinfect the wound during the subsequent rotation. The spray shell can continuously spray the outer wall of the cross hook lock sleeve, thereby improving the disinfection effect of the cross hook lock sleeve on the wound and improving the protection effect of the wound when it is stretched open. Because the rotating ring rotates on the outer wall of the cross hook lock sleeve, it can prevent the rotating ring from getting stuck when the cross hook lock sleeve rotates.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

During the downward movement of the arc plate 672, it will contact the top of the cross hook lock sleeve 657, so that the cross hook lock sleeve 657 moves downward along the outer wall of the cross rod 655, thereby expanding the hooking range of the cross hook lock sleeve 657, improving the stability of the wound opening, and indirectly improving the wound opening effect.

[0037] When the cross hook lock sleeve 657 descends, the cross hook lock sleeve 657 drives the rotating ring 673 to descend, and the rotating ring 673 drives the rotating bar 681 to descend. Limited by the slide groove 683, the rotating bar 681 drives the slider 682 to slide along the inner wall of the slide groove 683. During the movement of the slider 682, the cross bar 685 is driven to move, and the cross bar 685 drives the piston plate 686 to move. The piston plate 686 slides inside the liquid storage shell 684 to squeeze the disinfectant inside the liquid storage shell 684, so that the disinfectant inside the liquid storage shell 684 enters the inside of the connecting pipe 687, and the disinfectant enters the inside of the elastic tube 688 through the connecting pipe 687, and the disinfectant The venom enters the interior of the spray shell 689 through the elastic tube 688, and the disinfectant is sprayed toward the outer wall of the cross hook lock sleeve 657 through the spray shell 689 to prevent the applied disinfectant from being completely absorbed by the wound during the rotation of the cross hook lock sleeve 657, and the wound cannot be disinfected during the subsequent rotation process. The spraying setting of the spray shell 689 can continuously spray the outer wall of the cross hook lock sleeve 657, thereby improving the disinfection effect of the cross hook lock sleeve 657 on the wound, and laterally improving the protection effect when the wound is stretched open, because the rotating ring 673 rotates on the outer wall of the cross hook lock sleeve 657, which can prevent the rotating ring 673 from getting stuck when the cross hook lock sleeve 657 rotates.
