AI Technical Summary
Traditional CT scans cannot accurately reflect the deformities of the foot and ankle in a standing position, and existing standing weight-bearing CT scan equipment is expensive and has limited application.
Design a lower limb weight-bearing device for supine CT scans. By setting up an examination table assembly and a foot pedal, the patient lies on the transfer plate with knees bent, and the weight is provided by a return spring to simulate the examination in a standing position.
It enables simulated standing examination in a lying position, provides load-bearing capacity, has a simple structure, obvious effects, reduces equipment costs, and expands the scope of application.

Abstract
Claims
1. A lower extremity weight-bearing device for use in prone CT scanning, characterized in that, include: The base plate (1) has an examination table assembly slidably connected to one end of the base plate (1), and a foot pedal is provided at the other end of the base plate (1). In the initial state, the patient lies on the examination table assembly with knees bent, and the patient's feet are on the foot pedal. The inspection table assembly includes two parallel and spaced slide rails (2) and matching slide seats. The same transfer plate (3) is fixedly installed on the slide seats of the two slide rails (2). A support plate (4) is installed laterally at the end of the slide rail (2) away from the foot pedal. One end of the return spring (5) is installed on the support plate (4), and the other end of the return spring (5) is installed at the bottom of the transfer plate (3).
2. A lower extremity weight-bearing device for use in a prone CT scan as in claim 1, wherein: The transfer plate (3) is also provided with limiting baffles (6) at both ends, and the patient's shoulder can rest against the limiting baffles (6).
3. A lower extremity weight-bearing device for use in a prone CT scan as in claim 2, wherein: The bottom of the foot pedal is equipped with a reinforcing plate, and an electronic scale is also installed on the foot pedal.
4. A lower extremity weight-bearing device for use in a prone CT scan as claimed in claim 2 or 3, characterized in that: A cushioning pad is also installed where the limiting baffle (6) contacts the patient's shoulder.
5. A lower extremity weight-bearing device for use in prone CT scanning as claimed in claim 4, characterized in that: The transfer plate (3) is also provided with handles at both ends.
