The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0021] First embodiment:

[0022] See also Figure 1 to Figure 4 ,in Figure 1 This is a front view of the first embodiment of the utility model. Figure 2 The utility model Figure 1 The cross-sectional view along the AA line. Figure 3 The utility model Figure 1 A partial enlarged view of point B in the middle. Figure 4 The utility model Figure 2 A partial enlarged view of point C in the middle.

[0023] The utility model provides a hallux valgus osteotomy guide plate, comprising a left guide plate 101, a right guide plate 102 and a binding mechanism, wherein the binding mechanism comprises a fixing belt 108, a rotating rod 109, a storage block 110 and two fixing rings 113, and the rotating member comprises two rotating blocks 114 and a rotating ring 115. The above-mentioned scheme solves the problem that the device needs to use the fixing belt 108 to fix to the patient's foot, and the binding method of the fixing belt 108 is more complicated, which makes it inconvenient to quickly disassemble and assemble the device, and when not in use, the fixing belt 108 is prone to be randomly placed. It can be understood that the above-mentioned scheme can be used in the scene of hallux valgus osteotomy surgery, and can also be used to solve the problem that the binding belt is inconvenient to store.

[0024] According to this specific embodiment, a sliding frame 103 is provided above the left guide plate 101, a fixing belt 108 slot 104 is provided below the left guide plate 101, and the outer ends of the left guide plate 101 and the right guide plate 102 have the same structure, a connecting slot 105 is provided at one end of the left guide plate 101, and a fastening rod 106 is provided above the connecting slot 105, and a telescopic rod 107 is provided at one end of the right guide plate 102, and the telescopic rod 107 is connected to the connecting slot 105. The connecting groove 105 is slidably connected and located in the connecting groove 105, and the fastening rod 106 and the telescopic rod 107 are mutually abutted. The setting of the connecting groove 105 facilitates the telescopic rod 107 to be slidably installed in the connecting groove 105. The telescopic rod 107 is fixed in position by rotating the fastening rod 106 so as to extend and shorten the device as a whole to adapt to the transverse guidance of the first metatarsal bones of different lengths of different patients, and the device is convenient for telescopic storage.

[0025] Among them, a rectangular block 111 is provided at one end of the rotating rod 109, and a rotating member is sleeved on the rectangular block 111. An annular clamping block 112 is provided at one end of the fixing belt 108 groove 104. The fixing belt 108 is fixedly connected to the fixing belt 108 groove 104 and is located on one side of the fixing belt 108 groove 104. The fixing belt 108 is also fixedly connected to the rotating rod 109 and is located in the middle of the rotating rod 109 and passes through the other side of the fixing belt 108 groove 104. The rotating rod 109 is rotatably connected to the fixing belt 108 groove 104 and is located in the fixing belt 108 groove 104. The rotating rod 109 is also rotatably connected to the storage block 110 and is located in the storage block 110. The storage block 110 is fixedly connected to the fixing belt 108 groove 104 and is located in the fixing belt 108 groove 104. The fixing belt 108 can be used to easily bind the device to the patient's foot. The rotating rod 109 can easily store the fixing belt 108 in the storage block 110. The rotating member cooperates with the rectangular block 111 to facilitate the rotation of the rotating rod 109. Finally, the annular clamping block 112 is used to clamp and fix it, thereby preventing the fixing belt 108 from loosening.

[0026] Secondly, the two fixing rings 113 are respectively fixedly connected to the rotating rod 109 and are located at both ends of the rotating rod 109, and the two fixing rings 113 are also respectively abutted against the fixing belt 108 groove 104 and are located on both sides of the fixing belt 108 groove 104. The fixing rings 113 can be used to easily limit the rotation of the rotating rod 109, so that the rotating rod 109 can rotate in the storage block 110.

[0027] Again, the two rotating blocks 114 are respectively fixedly connected to the rotating ring 115 and are located on the outside of the rotating ring 115. The rotating ring 115 is slidably connected to the rectangular block 111 and is sleeved on the rectangular block 111. The two rotating blocks 114, the rotating ring 115 and the annular clamping block 112 cooperate with each other, so as to prevent the fixing belt 108 from loosening.

[0028] When the utility model is used to store or fix the fixing belt 108, the fixing belt 108 is matched with the rectangular block 111 by rotating the rotating part, thereby transmitting the rotating rod 109, and the rotating rod 109 winds up the fixing belt 108 and stores the fixing belt 108 in the storage block 110. When it is wound to a suitable length, the rotating part slides on the rectangular block 111 and is clamped and fixed with the annular clamping block 112, thereby preventing the fixing belt 108 from loosening. This fixing method is simple and convenient and worthy of promotion. In this way, the need to use the fixing belt 108 to fix the patient's foot is solved. Since the bundling method of the fixing belt 108 is more cumbersome, it is not convenient to quickly disassemble and assemble the device, and when not in use, the fixing belt 108 is prone to being randomly placed. Technical problems.
