DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-3 As shown, the utility model provides a technical solution: a nail remover for clinical application, including a fixing plate 3, a bottom plate 1 is fixedly installed on one side of the fixing plate 3 located at the bottom of the nail remover plate 13, and an elastic pad 2 is fixedly installed on the top of the bottom plate 1. Because of the elastic pad 2, the position where the patient needs to remove the bone nail is placed on the top of the elastic pad 2, thereby reducing the pain caused by the patient directly placing the affected part on the top of the bottom plate 1 and colliding with the bottom plate 1.

[0021] The two ends of the top of the fixing plate 3 are symmetrically fixed with mounting posts 4, and the tops of the two groups of mounting posts 4 are fixedly installed with top plates 5, the surfaces of the mounting posts 4 are slidably installed with sliding blocks 6, and one side of the surface of the sliding block 6 is fixedly installed with a pressing plate 7, and the surface of the mounting posts 4 located at the bottom of the sliding block 6 is provided with a lifting spring 8, and by providing the lifting spring 8, after the bone screw is stuck in the corresponding nail removal groove 15, the lifting spring 8 rebounds to lift the sliding block 6, thereby controlling the connecting plate 9 to drive the nail removal plate 13 to move upward, and the bone screw is extracted;

[0022] A connecting plate 9 is fixedly installed between the two groups of sliding blocks 6; a fixed clamping plate 10 is fixedly installed at the bottom of the connecting plate 9 close to the pressure plate 7, and the fixed clamping plate 10 corresponds to the fixed hook 21. Because the fixed clamping plate 10 is provided, pressing down the sliding block 6 drives the connecting plate 9 to move downward until the fixed clamping plate 10 passes over the fixed hook 21, so that the fixed hook 21 clamps and fixes the fixed clamping plate 10, ensuring that when the sliding block 6 is released, the connecting plate 9 will not move up away from the fixed plate 3.

[0023] Three groups of moving columns 11 are slidably installed on the top of the connecting plate 9, and a paddle plate 12 is fixedly installed on one end of the three groups of moving columns 11 located on the top of the fixed clamping plate 10, and a nail removal plate 13 is fixedly installed on one end of the three groups of moving columns 11 away from the paddle plate 12, and a compression spring 14 is provided on the surface of the moving column 11 located between the connecting plate 9 and the nail removal plate 13. By providing the compression spring 14, when the connecting plate 9 is loosened, the nail removal plate 13 can be pushed toward the patient's injured part under the rebound effect of the compression spring 14, ensuring that the nail removal groove 15 can be stuck on the corresponding bone nail surface;

[0024] Three groups of nail removal grooves 15 are equidistantly arranged on one side of the top of the nail removal plate 13 away from the movable column 11, and the nail removal grooves 15 correspond to the central position of the top of the elastic pad 2. Because of the provision of the nail removal grooves 15, when the nail removal grooves 15 are stuck on the corresponding bone screw surface, the nail removal plate 13 is controlled to be away from the patient's injured part, thereby removing the bone screw.

[0025] A bottom block 16 is fixedly installed at the central position of one side of the top of the fixing plate 3. A mounting plate 17 is fixedly installed on one side of the top of the bottom block 16, and two groups of clamping columns 18 are slidably installed on one side of the mounting plate 17, and one end of the two groups of clamping columns 18 passes through the mounting plate 17 and is fixedly installed with an end plate 19. A clamping spring 20 is provided on the surface of the clamping column 18 located on the side of the mounting plate 17 away from the end plate 19, and a fixed hook 21 is fixedly installed on one end of the two groups of clamping columns 18 away from the end plate 19. By providing the clamping spring 20, the fixed hook 21 is pushed toward the top of the fixed clamping plate 10 under the rebound action of the clamping spring 20, thereby clamping and fixing the fixed clamping plate 10.

[0026] The working principle of the utility model is:

[0027] The two groups of pressure plates 7 are pushed downward to control the sliding block 6 to drive the connecting plate 9 to slide down on the surface of the mounting column 4 until the fixed card plate 10 contacts the top of the fixed hook 21, and the pressure plate 7 is continued to be pressed downward to make the fixed card plate 10 pass over the fixed hook 21, and the clamping spring 20 rebounds to push the fixed hook 21 to the top of the fixed card plate 10, and the fixed card plate 10 is clamped and fixed, and the dial plate 12 is pushed to drive the nail removal plate 13 to approach the connecting plate 9, and the patient's injured part is placed on the top of the elastic pad 2 so that the bone nail at the injured part corresponds to the nail removal groove 15, and the dial plate 12 is released. Under the rebound action of the compression spring 14, the nail removal plate 13 is pushed toward the bone nail, so that the nail removal groove 15 is stuck at the top of the bone nail, and the end plate 19 is pulled to drive the fixed hook 21 away from the fixed card plate 10, and under the elastic action of the lifting spring 8, the sliding block 6 is pushed toward the top plate 5, driving the nail removal plate 13 to move up and remove the bone nail.
