The front and rear positions of the horizontal support plate are adjusted according to the patient's body shape, and the soft pads and the horizontal support plate are used to support the patient's legs in a normal state. When it is necessary to support the patient's legs in a flexed knee state, in addition to the above steps, it is also necessary to insert multiple pins into the corresponding pin slots, and use the flexed knee support pad to support the patient's legs in a flexed knee state.

[0016] In the utility model, the CT examination leg support device can not only support the patient's legs in a normal state, but also stably support the patient's legs in a flexed knee state according to the examination requirements, by means of a knee flexion support pad that can be detached and plugged on the top of the horizontal support plate, thereby expanding the scope of application and having strong feasibility.

[0017] In the utility model, the CT examination leg support device can change the front and rear position of the horizontal support plate on the CT examination bed by setting the front and rear position adjustment mechanism, and then support the legs of patients with different body shapes, and the use effect is good;

[0018] The utility model can not only support the patient's legs in a normal state, but also stably support the patient's legs in a flexed knee state according to examination requirements, thereby expanding the scope of application and having strong feasibility. BRIEF DESCRIPTION OF THE DRAWINGS
