[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0017] Please refer to Figure 1-2, the present utility model provides a technical solution: a self - supporting retractor, including a fixed frame 1, a guide rod 2 is provided on the fixed frame 1, two symmetrically arranged sleeves 3 are slidably arranged on the guide rod 2, and an adjusting plate 31 is provided on the side of the sleeve 3. At the bottom of the end of the adjusting plate 31 away from the sleeve 3, there is a hook plate 32 for retraction. An adjusting member for controlling the position of the adjusting plate 31 is movably inserted through the middle of the fixed frame 1, and the adjusting member controls the adjusting plate 31 and the sleeve 3 to move axially along the guide rod 2.
[0018] Further, the adjusting member includes an adjusting screw rod 5 movably inserted through the middle of the fixed frame 1. A nut 4 is provided in the middle of the guide rod 2. The adjusting screw rod 5 is threadedly connected to the nut 4. At one end of the adjusting screw rod 5 close to the adjusting plate 31, a hinge seat 51 is rotatably provided. On the hinge seat 51, two symmetrically arranged connecting plates 52 are rotatably provided. And the end of the connecting plate 52 away from the hinge seat 51 is rotatably connected to the adjusting plate 31. By rotating the adjusting screw rod 5, when the adjusting screw rod 5 rotates, it drives the hinge seat 51 to move. The hinge seat 51 pushes the adjusting plate 31 to move through the connecting plate 52. The adjusting plate 31 drives the sleeve 3 to move on the guide rod 2. At the same time, the adjusting plate 31 drives the hook plate 32 to move. During the movement of the hook plate 32, the tissue is retracted. In the subsequent holding stage, only need to hold the handle 6 tightly, and it is not necessary to exert force anymore to maintain the retracted state.
[0019] Further, a handle 6 is provided on the side of the fixed frame 1 away from the adjusting plate 31, which is convenient for the hand - held operation of the entire retractor.
