The bottom of the fixing frame 2 is fixedly connected to the base 1; the arc-shaped telescopic frame 3 includes an arc-shaped fixing tube 31 and a sliding rod 32, the fixing tube 31 is fixedly connected to the upper part of the fixing frame 2, and the sliding rod 32 is partially slidably installed inside the fixing tube 31; the first support frame 4 is fixedly installed at one end of the fixing tube 31, and the first support frame 4 is used to position the patient's thigh; the second support frame 5 is fixedly installed on the sliding rod 32, and the second support frame 5 is used to position the patient's lower leg; the locking screw 33 is threaded onto the fixing tube 31, and the locking screw 33 is used to abut against the sliding rod 32 to lock the position of the sliding rod 32.
[0028] With the above setup, when in use, first place the patient's thigh on the first support frame 4, adjust the extension length of the sliding rod 32 until the patient's lower leg is placed on the second support frame 5, and then rotate the locking screw to press against the sliding rod 32, thereby locking the position of the sliding rod 32. The structure is simple, with few parts, reducing equipment costs, and has good stability. In addition, the locking screw 33 is close to the first support frame 4, making it easy for the patient to lock the second support frame 5 by themselves, making the operation more convenient.
[0029] In this embodiment of a leg positioning device for radiological examinations, two first support frames 4 and two second support frames 5 are provided. The two first support frames 4 are fixedly installed on opposite sides of the fixing tube 31, and the two second support frames 5 are fixedly installed on opposite sides of the sliding rod 32. One set of first support frames 4 and second support frames 5 is used to position one of the patient's legs, and the other set is used to position the other leg. This arrangement facilitates placing both of the patient's legs on the two sets of first support frames 4 and second support frames 5 together, improving patient comfort.
[0030] In a leg positioning device for radiological examinations according to this embodiment, a horizontal mounting rod 34 is fixedly installed on the fixing tube 31. The horizontal mounting rod 34 is perpendicular to the fixing tube 31, and its middle part is connected to the fixing tube 31. Two first support frames 4 are symmetrically fixedly installed at opposite ends of the horizontal mounting rod 34. This arrangement facilitates the installation of the two first support frames 4 and improves the installation stability of the first support frames 4.
[0031] In this embodiment of a leg positioning device for radiological examinations, the fixing tube 31 has two parallel sliding channels, and a sliding rod 32 is slidably installed in each sliding channel. Two second support frames 5 are respectively installed on the two sliding rods 32. This arrangement facilitates independent adjustment of the angles of the two second support frames 5 to meet the patient's comfort. The patient can position the affected leg on either set of first support frames 4 and second support frames 5 to meet various needs.
[0032] In a leg positioning device for radiological examinations according to this embodiment, the two ends of the horizontal mounting rod 34 are fixedly connected to the fixing frame 2 via diagonal rods 35. The horizontal mounting rod 34 is supported by the diagonal rods 35, and the horizontal mounting rod 34, diagonal rods 35, and fixing frame 2 form a triangular stable structure, improving the connection stability of the horizontal mounting rod 34.
[0033] In a leg positioning device for radiological examinations according to this embodiment, a plurality of positioning holes 321 are formed on the sliding rod 32 along its sliding path direction for the locking screw 33 to pass through. The locking screw 33 passes through any one of the positioning holes 321 to position the sliding rod 32 in the corresponding position. By using the locking screw 33 to position the sliding rod 32 through the positioning hole 321, the positioning stability of the sliding rod 32 is improved.
[0034] In a leg positioning device for radiological examinations according to this embodiment, a first support frame 4 is mounted on a fixed tube 31 via a first ball joint structure 41, and a second support frame 5 is mounted on a sliding rod 32 via a second ball joint structure 51. Positioning elements 44 are installed on both the first and second ball joint structures 41 to lock the first support frame 4 and the second support frame 5. This configuration, using the first ball joint structure 41 to mount the first support frame 4 and the second ball joint structure 51 to mount the second support frame 5, facilitates adjustment of the angles of the first and second support frames 4 and 5 to meet the needs of different patients.
[0035] In a leg positioning device for radiological examination in this embodiment, the first ball joint structure 41 and the second ball joint structure 51 both include a limiting sleeve 42 and a limiting ball 43. The limiting ball 43 is rotatably limited in the limiting sleeve 42. The limiting ball 43 is fixedly connected to the corresponding support frame. The limiting sleeve 42 is fixedly connected to the corresponding sliding rod 32.
[0036] In a leg positioning device for radiological examinations according to this embodiment, the positioning component 44 includes a positioning screw. A threaded hole is formed on the side wall of the limiting sleeve 42, and the positioning screw is installed in the threaded hole. The positioning screw is used to press against the limiting ball 43. With this configuration, after adjusting the position of the limiting ball 43, the limiting ball 43 is pressed and fixed by rotating the positioning screw. The structure is simple and the operation is convenient.
[0037] In this embodiment of a leg positioning device for radiological examination, two sliding rods 32 are fixedly connected by bolts 6 to achieve synchronous extension and retraction. This configuration allows for independent control of the extension length of the two sliding rods 32, and also enables simultaneous control of their extension lengths after the two sliding rods 32 are fixedly connected by bolts 6, making operation convenient.
