[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.
[0022] like Figure 1-6 As shown, the utility model provides a technical solution: a bone orthosis, including a mounting block 1 and an operating table 5, one side of the mounting block 1 is fixedly connected with a fixing mechanism 4, the fixing mechanism 4 includes a slide groove 45 and a shell 46, a moving groove 43 is provided on the top of the shell 46, a pulling rod 41 is slidably arranged in the moving groove 43, one end of the pulling rod 41 is fixedly connected with a moving block 42, the moving block 42 is slidably connected to the slide groove 45, a spring 44 is arranged in the slide groove 45, one end of the spring 44 is fixedly connected to the shell 46, the other end of the spring 44 is fixedly connected to one side of the moving block 42, the other side of the moving block 42 is arranged in an inclined shape, a fixing belt outlet 47 is arranged on the side of the shell 46 close to the mounting block 1, and a fixing belt 3 is fixedly connected to the other side of the mounting block 1;
[0023] Rectangular teeth are provided on one side of the fixed belt 3, and the fixed belt 3 is limited and fixed by the moving block 42. One side of the moving block 42 is arranged in an inclined shape, which is more conducive to the rectangular teeth of the fixed belt 3 applying force. Under the action of the spring 44 and the rectangular teeth of the fixed belt 3, the moving block 42 reciprocates under the movement of the fixed belt 3, and the fixed belt 3 is limited and fixed.
[0024] The two mounting blocks 1 are symmetrical about the operating table 5. Two slidably connected gear bars 2 are inserted in the operating table 5. One end of the gear bar 2 is fixedly connected to the mounting block 1. Through the mutual cooperation between the gear bar 2 and the mounting block 1, in order to prevent the gear bar 2 from detaching from the operating table 5 during the extension and retraction process, a limiting tooth is set at the other end of the gear bar 2. Through the mutual cooperation between the operating table 5 and the gear bar 2, the operating table 5 provides support for the movement of the gear bar 2, and the operating table 5 provides an operating space for the movement and limitation of the gear bar 2.
[0025] A gear 7 is provided inside the operating table 5, one end of the gear 7 passes through the operating table 5 and is rotatably connected to the operating table 5, the gear 7 is meshed with two gear bars 2, one end of the gear 7 is fixedly connected with a turntable 6, and the gear 7 is driven to rotate by rotating the turntable 6. Due to the meshing action of the gear 7 and the gear bar 2, the two gear bars 2 respectively drive the mounting block 1 on one side to move.
[0026] A limit groove 61 is provided on the turntable 6, and a moving plate 63 is provided in the limit groove 61. A threaded rotating rod 62 connected by a thread is inserted into the moving plate 63. The threaded rotating rod 62 passes through both sides of the turntable 6 and is rotatably connected to the turntable 6. The moving plate 63 is fixedly connected to a limit shaft 64 facing one side of the operating table 5. Since the threaded rotating rod 62 is rotatably connected to the turntable 6, rotating the threaded rotating rod 62 will only drive the moving plate 63 threadedly connected to the threaded rotating rod 62 to move in the limit groove 61, thereby driving the limit shaft 64 to move. A plurality of evenly distributed limit holes 51 are provided on one side of the operating table 5, and the limit holes 51 are slidably connected to the limit shaft 64.
[0027] The limiting hole 51 is arranged on the outside of the turntable 6 and close to the side of the turntable 6, which is convenient for observing the corresponding position of the limiting shaft 64 and the limiting hole 51, and more convenient for fixing the orthosis. The cooperation between the limiting shaft 64 and the limiting hole 51 limits the telescopic movement of the orthosis.
[0028] A cushion 11 is provided on one side of the mounting block 1 and the operating table 5. Because of the cushion 11, the cushion 11 protects the user during use and can better fit the bones of different parts of the user.
[0029] The working principle of the utility model is:
[0030] First, determine the user's bone. When taking out the orthosis, the two gear strips 2 of the orthosis are in the initial state. The two gear strips 2 can no longer shrink, and one end of the limit shaft 64 is in the limit hole 51. The orthosis is adjusted according to the length of the bone. First, rotate the threaded rotating rod 62 counterclockwise to make the movable plate 63 move in the limit groove 61, thereby driving the limit shaft 64 to move away from the operating table 5. The limit shaft 64 is disengaged from the limit of the limit hole 51, so that the turntable 6 can rotate, and the gear 7 fixedly connected to the turntable 6 is driven to rotate. Through the meshing of the gear 7 and the gear strip 2, the two mounting blocks 1 move in the direction away from each other to reach a suitable position, and the threaded rotating rod 62 is rotated again. One end of the limiting shaft 64 moves into the limiting hole 51 to limit the gear bar 2, which is placed on the user's bone, and the fixing belt 3 is passed through the fixing belt outlet 47. Under the action of the fixing belt 3 and the spring 44, the moving block 42 reciprocates under the movement of the fixing belt 3. Under the action of the spring 44, the moving block 42 automatically limits the passing fixing belt 3, so that the fixing belt 3 can only be tightened to complete the fixation of the orthosis. After the orthosis is used, the pulling rod 41 is pulled to move in the moving groove 43 to the side away from the mounting block 1, thereby driving the moving block 42 fixedly connected to the pulling rod 41 to move, thereby releasing the restriction of the moving block 42 on the fixing belt 3, and the orthosis can be removed after pulling the fixing belt 3.
