Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-4 As shown, this utility model provides a technical solution: an adjustable fracture reduction device, including a fracture reduction device assembly 1, with adjustment components 2 at both ends of the fracture reduction device assembly 1, and a support component 3 at the top of the fracture reduction device assembly 1. The fracture reduction device assembly 1 includes a support column 101, with support rings 102 symmetrically installed on the outer side of the support column 101. The adjustment component 2 includes two adjustment rods 201, which are movable at both ends of the support column 101. Multiple friction pads 202 are distributed on the top of the adjustment rods 201, and connecting rings 203 are fixedly installed on the outer side of the adjustment rods 201. Fastening bolts 204 are installed at both ends of the top of the support column 101, and buckles 103 are symmetrically installed on the outer side of the support column 101. The side of the buckles 103 is connected to the reduction ring 104, and a fastener 105 passes through the interior of the reduction ring 104. The fasteners 204 are connected to the friction pads 202.

[0023] In this embodiment, by rotating the fastening bolt 204 to loosen it, the adjusting rod 201 slides inside both ends of the support column 101, which is beneficial for timely adjustment according to the patient's body shape. When the adjusting rod 201 moves to the appropriate position, rotating the fastening bolt 204 connects the fastening bolt 204 with the friction pad 202, which helps to limit the adjustment rod 201. The operation is convenient and quick to adjust to the appropriate length, accurately fitting the needs of the surgical operation, thereby ensuring the accuracy of fracture reduction instrument assembly 1 for fracture reduction. It does not require complicated tools or long-term cooperation from multiple people, thus improving the accuracy of reduction.

[0024] Example 2: As Figures 1-4 As shown, the support assembly 3 includes two movable rods 302, with support rods 301 movably connected to both ends of the movable rods 302. Guide members 303 are symmetrically installed on the outer side of the connecting ring 203. The movable rods 302 are set on the support ring 102, and one end of the support rod 301 passes through the interior of the guide member 303.

[0025] In this embodiment, rotating the fastener 105 helps to fix the patient's fracture point. The support rod 301 moves inside the movable rod 302, and one end of the support rod 301 passes through the guide member 303, which helps to guide the support rod 301. The support rod 301 and the movable rod 302 help to improve the stability of the fracture reduction device assembly 1, ensuring the stability and reliability of the fracture reduction device assembly 1 during use, greatly improving the accuracy of fracture reduction, and reducing reduction deviation caused by unstable operation.

[0026] The working principle of this embodiment is as follows: In use, firstly, rotating the fastening bolt 204 loosens the adjusting rod 201, allowing it to slide inside both ends of the support column 101. This facilitates timely adjustment according to the patient's body shape. When the adjusting rod 201 moves to the appropriate position, rotating the fastening bolt 204 connects the fastening bolt 204 with the friction pad 202, which helps to limit the adjustment rod 201. This convenient and quick adjustment to the appropriate length precisely meets the needs of surgical operations. Rotating the fastener 105 helps to fix the patient's fracture point. The support rod 301 moves inside the movable rod 302, and one end of the support rod 301 passes through the guide 303, which helps to guide the support rod 301. The support rod 301, in conjunction with the movable rod 302, helps to improve the stability of the fracture reduction instrument assembly 1, ensuring the stability and reliability of the fracture reduction instrument assembly 1 during use.
