[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0021] Reference Figure 1-Figure 3 An ankle joint replacement measuring device includes a base plate 1. A second fixing block 13 is welded to the upper surface of the base plate 1. Round rods 15 are welded to both sides of the second fixing block 13. A connecting frame 14 is rotatably connected to the outer side of the round rods 15. A vertical plate 4 is welded to the top of the connecting frame 14. A fixing plate 5 is fixed to one side of the vertical plate 4 by bolts. A strap assembly for binding the leg and foot is provided on one side of the fixing plate 5 and the base plate 1. Angle scales 17 are provided on both sides of the connecting frame 14. A pointer 16 for indicating the angle scales 17 is provided on the outer side of the round rods 15. A sliding groove 21 is opened on one side of both the vertical plate 4 and the base plate 1. Two sliders 19 are slidably connected in both sliding grooves 21. A scale plate 22 is fixed to one side of each of the two sliders 19 by bolts. A scale plate 22 is fixed to one side of the other two sliders 19. Two limiting frames 20 are welded together, and the scale plate 22 passes through the limiting frames 20. An indicator strip for indicating the scale plate 22 is welded between two adjacent limiting frames 20. The upper surface of the base plate 1 is provided with a locking assembly to fix the rotation angle of the vertical plate 4. When the lower leg is placed against the fixed plate 5 and the foot is placed on the base plate 1, the bending angle between the lower leg and the foot will cause the vertical plate 4 to rotate on the round rod 15 through the connecting frame 14. When the vertical plate 4 stops rotating, the angle between the foot and the lower leg is measured by the pointer 16 on the angle scale 17. Then, the slider 19 is pulled to move in the slide groove 21. The length and height of the ankle joint are measured by the scale plate 22, so that the ankle joint can be accurately measured, improving the accuracy of ankle joint replacement.

[0022] In this utility model, the strap assembly includes multiple connecting blocks 2, which are uniformly and symmetrically welded to one side of the base plate 1 and the fixing plate 5. Each side of the multiple connecting blocks 2 is provided with a strap 3, and an anti-slip buckle 6 is provided between two adjacent straps 3 to tighten the strap 3. After the lower leg is placed on the fixing plate 5 and the foot is placed on the base plate 1, the foot and lower leg are tied and fixed by the strap 3, thereby preventing the foot and lower leg from moving.

[0023] The locking assembly includes a limiting groove 8, which is formed on the upper surface of the base plate 1. A sliding plate 10 is slidably connected within the limiting groove 8. A connecting plate 7 is rotatably connected to the upper surface of the sliding plate 10. A first fixing block 12 is rotatably connected to one side of the connecting plate 7 and is fixed to the vertical plate 4. A threaded hole is formed on the upper surface of the sliding plate 10, and a locking bolt 11 for locking the sliding plate 10 is threaded into the threaded hole. During the rotation of the vertical plate 4, the sliding plate 10 is pushed to move within the limiting groove 8 by the connecting plate 7. At the same time, the connecting plate 7 rotates between itself, the sliding plate 10, and the first fixing block 12. When the vertical plate 4 stops rotating, the locking bolt 11 is rotated to engage with the base plate 1. The sliding plate 10 is locked in tight contact, thereby supporting and fixing the vertical plate 4 through the connecting plate 7 to prevent the vertical plate 4 from rotating and ensuring the accuracy of the measurement. Two positioning posts are fixed in the limiting groove 8 by bolts. Both positioning posts pass through the sliding plate 10. Springs 9 are sleeved on the outside of the two positioning posts, and the two ends of the springs 9 are fixed to the sliding plate 10 and the base plate 1, respectively. A telescopic rod 18 is fixed to one side of the slider 19 by bolts. Since the foot and lower leg have thickness, the telescopic rod 18 can be pulled out after the slider 19 moves to the appropriate position. The telescopic rod 18 is used to determine whether the slider 19 has moved to the designated position. Rubber pads are glued to one side of the fixing plate 5 and the base plate 1.

[0024] Working principle: When needed, place the lower leg against the fixing plate 5 and the foot on the base plate 1. Then, use the straps 3 to secure the foot and lower leg. The bending angle between the lower leg and foot causes the vertical plate 4 to rotate on the round rod 15 via the connecting frame 14. During this rotation, the vertical plate 4 pushes the slide plate 10 within the limiting groove 8 via the connecting plate 7. Simultaneously, the connecting plate 7 rotates between itself, the slide plate 10, and the first fixing block 12. After the vertical plate 4 stops rotating, rotate the locking bolt 11 to make it tightly contact the base plate 1, locking and securing the slide plate 10. The vertical plate 4 is supported and fixed by the connecting plate 7 so that it no longer rotates. At this time, the angle between the foot and the lower leg can be measured by the pointer 16 on the angle scale 17. Then, the slider 19 is pulled to move in the slide groove 21. The length and height of the ankle joint are measured by the scale plate 22, so that the ankle joint can be accurately measured, which improves the accuracy of ankle joint replacement. Since the foot and the lower leg have thickness, after the slider 19 moves to the appropriate position, the telescopic rod 18 can be pulled out, so as to determine whether the slider 19 has moved to the designated position by the telescopic rod 18.

[0025] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
