Technical Field

[0001] The utility model relates to the field of X-ray photography auxiliary equipment, in particular to a hindfoot force line position X-ray photography auxiliary device. Background Art

[0002] Hindfoot alignment radiography, proposed and named by foot and ankle surgeon Saltzman, is commonly used to observe skeletal alignment and measure and assess alignment in the foot and ankle. It is currently a commonly used imaging procedure in foot and ankle surgery. In this examination, the patient stands on one leg with the calf perpendicular to the ground. The X-ray tube is placed behind the calf, with the centerline tilted 20° toward the foot and aimed directly at the midpoint between the medial and lateral malleolus.

[0003] In the past, patients were required to stand on one leg by themselves. During the standing process, it was easy for them to tilt, sway, or have their calves not perpendicular to the ground. This would lead to errors in force line measurement and examination failure. Utility Model Content

[0004] The purpose of the present invention is to provide a hindfoot force line X-ray photography auxiliary device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: it includes an external frame assembly, a calf fixing assembly is installed below the front end of the external frame assembly, and the calf fixing assembly includes a side plate, a second spring, a guide rod and a clamping plate, the second spring is connected to the middle part of the side of the side plate close to the central axis of the external frame assembly, and the guide rod is connected through the front and rear sides of the side of the side plate close to the central axis of the external frame assembly, and the second spring is connected to the clamping plate on the side away from the side plate.

[0006] Preferably, the outer frame assembly includes a base frame, a leg frame, a backrest and a rubber pad, and the rear end of the base frame is connected to the leg frame, the backrest is installed above the leg frame, and the rubber pad is laid above the base frame.

The outer frame assembly 1 also includes an adjusting cylinder 105, a pressure sensor 106 and a detector mounting bracket 107, and the front end of the base frame 101 is penetrated by the adjusting cylinder 105, the telescopic end of the adjusting cylinder 105 is installed with the pressure sensor 106, and the end of the pressure sensor 106 away from the adjusting cylinder 105 is connected to the detector mounting bracket 107;

[0022] The base frame 101 and the rubber pad 104 are both made of transparent material.

[0023] like Figure 2 and Figure 3 As shown, a leg support assembly 2 is installed behind the leg frame 102 , and armrest assemblies 3 are installed through the left and right sides of the backrest 103 .

[0024] like Figure 2As shown, the leg support assembly 2 includes a guide rail 201, a lifting slide block 202, a support frame 203 and a bracket 204, and the outside of the guide rail 201 is connected to the lifting slide block 202, one side of the lifting slide block 202 is connected to the support frame 203, and the side of the support frame 203 away from the lifting slide block 202 is connected to the bracket 204;

[0025] The equipment is provided with a bracket 204, and the height of the lifting sliding block 202 can be adjusted by the sliding structure between the lifting sliding block 202 and the guide rail 201. In addition, the bracket 204 and the support frame 203 are rotatably connected, and the support frame 203 and the lifting sliding block 202 are also rotatably connected. The position of the bracket is adjusted by two rotatable connections, which makes it convenient for the technician to place the patient's non-detection leg on the bracket, so that when the patient stands on one leg with the affected leg, the non-detection leg also has a support structure, which helps the human body to maintain stability.

[0026] like Figure 3 As shown, the handrail assembly 3 includes a handrail rod 301, a first spring 302, a connecting rod 303, a rubber triangular block 304 and an I-shaped sliding block 305, and the rear end of the handrail rod 301 is connected to the rubber triangular block 304, the first spring 302 is installed inside the handrail rod 301, and the rear end of the first spring 302 is connected to the connecting rod 303, and the rear end of the connecting rod 303 is connected to the I-shaped sliding block 305;

[0027] Pull the handrail 301 outward to separate the rubber triangle block 304 from the backrest 103. At this time, the height of the handrail 301 is adjusted by the sliding structure between the I-shaped sliding block 305 and the backrest 103. The handrail 301 is reset by the elastic structure formed between the first spring 302 and the connecting rod 303.

[0028] Working principle: First, install the equipment on the ground, the rear end of the equipment needs to be raised, and at the same time, the X-ray receiving end detector is installed at the lower end of the detector mounting frame 107. When the patient needs to use the equipment, first adjust the height of the bracket 204 according to his personal height. At this time, the height is adjusted by the sliding structure between the lifting sliding block 202 and the guide rail 201. When the bracket 204 is adjusted to the required height, the lifting sliding block 202 is fixed by the fixing bolt block on the lifting sliding block 202. The rotating structure between the bracket 204 and the support frame 203 and the rotating structure between the support frame 203 and the lifting sliding block 202 facilitates the technician to adjust the position of the bracket 204. When the adjustment of the bracket 204 is completed, the patient stands on the rubber pad 104 again, with his back leaning on the backrest 103 and his legs close to the leg frame 102. The clamping plate 404 is elastically retracted to the patient's calf part through the guide rod 403 and the second spring 402 and the side plate 401. The patient can hold the patient's legs perpendicular to the horizontal plane. When the patient stands up, he first pulls the handrail 301 outward with both hands to separate the rubber triangle block 304 from the backrest 103. At this time, the height of the handrail 301 can be adjusted by the sliding structure between the I-shaped sliding block 305 and the backrest 103 to facilitate the patient's support. When the handrail 301 is adjusted to the specified height, it is only necessary to release the handrail 301. At this time, the handrail 301 will be pulled up by the elastic structure formed by the first spring 302 and the connecting rod 303. Rod 301 is reset, allowing the rubber triangle 304 to re-engage the track on the backrest 103, making it easier for the patient to support himself. At the same time, the technician places the patient's non-test leg on the bracket 204 to lift it, allowing the patient to stand on one leg. Then, the technician adjusts the cylinder 105 to drive the detector mounting frame 107 to move until the detector mounting frame 107 is close to the toes. At this time, the value of the pressure sensor 106 changes, which immediately stops the adjustment of the cylinder 105, allowing the detector on the detector mounting frame 107 to just be close to the toes. The X-ray tube at the back of the device is then turned on, allowing the X-ray to irradiate the ankle from back to front and be received by the detector, thus completing the work. Figure 2 The leg frame 102 is shown with a hole at the rear to facilitate X-ray exposure.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
