Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to a remotely controllable standing frame for full-length lower limb radiography. Background Technology

[0002] When performing full-length lower limb radiographs, different clinicians have different requirements regarding the position of the patella on the image. A standard full-length lower limb radiograph usually requires the patient to stand with both patellae facing forward. Therefore, the radiologist needs to inform the patient of their standing position, whether their legs are together or apart, whether they should be "pigeon-toed" or "outward-toed," and the angle of their feet, etc. Typically, taking a standard full-length lower limb radiograph often requires the radiologist to squat or bend down to manually assist the patient in positioning. With the increasing prevalence of full-length lower limb radiographs, the workload is constantly increasing, often causing considerable hardship for radiologists. Therefore, there is an urgent need to design a device that improves adjustment efficiency and imaging accuracy. Utility Model Content

[0003] The problem to be solved by this utility model is to propose a remotely operated standing frame for full-length lower limb radiography that does not require manual assistance in positioning the patient.

[0004] To achieve the above objectives, the present invention provides a remotely controlled lower limb full-length radiography stand, comprising:

[0005] The base has a cavity for accommodating the cavity;

[0006] The drive unit is located outside the base;

[0007] An angle adjustment structure is set inside the receiving cavity, and its input end is connected to the driving device, which drives it to rotate.

[0008] The foot pedal, located above the base, is connected to the output end of the angle adjustment structure, and its angle changes as the angle adjustment structure rotates.

[0009] According to this utility model, the angle adjustment structure further includes a horizontally placed worm gear disposed in the accommodating cavity of the base, with both ends fixed to the two opposite side walls of the base; the input end of the worm gear is connected to a servo motor via a coupling; a vertically upward worm wheel shaft is disposed on one side of the worm gear, the bottom of the worm wheel shaft is fixed to the bottom wall of the base, the top of the worm wheel shaft is connected to the foot pedal, and a worm wheel that cooperates with the worm gear is assembled on the outer periphery of the worm wheel shaft, and the worm wheel and the worm gear cooperate to realize motion transmission.

[0010] According to this utility model, the driving device is a servo motor, which is fixed to the outer peripheral wall of the base by a bracket.

[0011] According to this utility model, the output shaft of the servo motor is further connected to the input end of the angle adjustment structure via a coupling.

[0012] According to this utility model, the angle adjustment structure is further divided into two sets, and correspondingly there are two sets of servo motors, each controlling one set of angle adjustment structure, so that the position of one foot can be adjusted individually according to the filming requirements.

[0013] According to this utility model, the top of the base is open and a top cover plate is detachably and fixedly connected thereto. The foot pedal is set on the top of the top cover plate, and the top of the worm gear shaft passes through the top cover plate and is connected to the foot pedal. The top of the worm gear shaft is fixedly connected to the top cover plate through a bearing seat.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] The lower limb full-length radiography standing frame involved in this utility model allows patients to simply stand on the corresponding foot pedals of the frame. Radiology operators can remotely drive the motor to rotate the foot pedals in different directions and angles, thereby adjusting the position of the patient's lower limbs. This significantly reduces the operational difficulty for radiology operators, protects their health, and greatly reduces communication between doctors and patients, thus lowering risks.

[0016] This invention eliminates the need for doctors to bend over for adjustment; remote operation allows for accurate adjustment of the patient's standing position and angle, reducing the workload of radiology staff while ensuring the image quality required for clinical use. It significantly improves imaging efficiency and accuracy, and avoids excessive physical exertion by radiology personnel. Attached Figure Description
