Description

Technical Field

[0001] The present invention relates to the technical field of fixing devices, and particularly to a fixing device. Background Art

[0002] Whole-body bone imaging examination in nuclear medicine departments is used to screen whether tumor patients have bone metastases and some benign lesions. Due to postural reasons, most people's feet will show an "outward-turning" shape when standing upright or lying flat. In this position, when imaging in the supine plane, a large part of the tibia and fibula of the bilateral lower limbs of the examinee will overlap, and the lesions of the two bones cannot be clearly distinguished in the whole-body bone imaging results. If the examinee is required to actively maintain an "inward-turning" position, the leg muscles of the examinee need to be in a contracted state, which cannot be maintained for a long time and is prone to fatigue. When imaging, the position changes of the lower limbs and feet of the examinee can cause artifacts in the image, bringing difficulties to correct diagnosis.

[0003] Most of the existing fixing devices for nuclear medicine bone imaging fix the feet of the patient on a special inclined plate and then use straps to bind the feet, which requires the help of both hands. The steps are relatively cumbersome and cannot be separated from the help of both hands. The feet cannot be tilted and fixed in one step. Using a unified fixing method and angle for different people will make some people feel uncomfortable, and the inspection efficiency is not high. Summary of the Invention

[0010] Preferably, the limiter is in the shape of a "work" character, the second connecting device is arranged at the top of the limiter, and the limiter is movably connected to the second connecting device.

[0011] Preferably, sliding plates are arranged on the left and right side surfaces of the fixing device, a fixing square plate is fixedly connected to the front end of the sliding plate, the fixing square plate is slidably connected to the fixing device, a fixing plate is arranged on the outer side surface of the sliding plate, the sliding plate and the fixing plate are slidably connected, the fixing plate is in a "7" - shaped structure, a rotating shaft is fixedly connected to the fixing plate, a threaded rod is rotatably connected to the rotating shaft, the threaded rod is threadedly connected to the sliding plate, and the fixing plate is fixedly connected to the connecting disc.

[0012] Preferably, arc - shaped sliding blocks are fixedly connected to the left and right side surfaces of the third connecting device, a middle connecting groove is arranged at the top of the arc - shaped sliding block, and a limiting plate is arranged at the top of the middle connecting groove.

[0013] Preferably, a fifth connecting device is fixedly connected to the inner surface of the fixing square plate, a connecting fixing disc is fixedly connected to the left side of the fifth connecting device, a sixth connecting device is rotatably connected to the central position of the connecting fixing disc, a connecting head and a sliding spring block are fixedly connected to the top end of the sixth connecting device, the other end of the sliding spring block is slidably connected to the third connecting device, and a rotating disc is rotatably connected to the bottom of the sixth connecting device.

[0014] Bone imaging in nuclear medicine is a commonly used imaging examination method in nuclear medicine, which can detect whether the morphology or metabolism of bone tissue is normal.

[0015] During the examination, it is usually necessary to tilt and fix the patient's foot. When in use, the patient places the foot in the middle of the fixing device.

[0016] During the backward movement of the fixed square plate, the rotating disk provided on its inner side will pass through the arc-shaped sliding block and reach the position of the middle connecting groove, and further fix the foot through the connecting head. The sliding spring block can ensure the mobility of the sixth connecting device and avoid jamming. The connecting fixed disk and the sixth connecting device form a lever to transmit the movement state of the rotating disk to the position of the connecting head.

[0017] After fixation, when it is necessary to place the subject's feet in the "pigeon-toed" position, there will be a certain distance interval between the tibia and fibula of both lower limbs at this time. In the whole-body bone planar imaging, the tibia and fibula are parallel. It is easy to distinguish the tibia, fibula and the location of the lesion. The second connecting device can be taken out, the insert fixedly connected to the bottom of the second connecting device can be inserted into the limiter, and the second connecting device can be placed towards the central area. Weight blocks can be placed on the loading device as needed to increase the load, so that the fixing device rotates inward through the rotating disk, thereby enabling the patient's feet to achieve the "pigeon-toed" position. When in use, appropriate weight blocks can be selected according to the patient's body posture to achieve the "pigeon-toed" position, which is suitable for different people and can effectively improve the comfort of the patient.

[0018] Beneficial effects:

[0019] 1. For this fixing device, during the examination, it is usually necessary to tilt and fix the patient's foot. When in use, the patient places the foot in the middle of the fixing device. After placement, the sole of the foot will push the pusher to move inward. During the inward movement of the pusher, the threaded disk fixedly connected to the pusher will be driven to move forward. During the forward movement of the threaded disk, the threaded surface drives the threaded rod to rotate on the rotating shaft, thereby driving the sliding plate threadedly connected to the rotating shaft to move backward, driving the fixed square plate fixedly connected to the sliding plate to move backward, and fixing the foot through the fixed square plate, replacing the manual strap fixation, which is more convenient to use.

[0020] 2. During the backward movement of the fixed square plate of this fixing device, the rotating disc provided on its inner side will pass through the arc-shaped sliding block and reach the position of the middle connecting groove, and further fix the foot through the connecting head. The sliding spring block can ensure the mobility of the sixth connecting device and prevent jamming. The connecting fixed disc and the sixth connecting device form a lever to transfer the movement state of the rotating disc to the position of the connecting head, thus replacing manual fixation and improving the inspection efficiency.

[0021] 3. For this fixing device, take out the second connecting device, insert the insert piece fixedly connected to the bottom of the second connecting device into the limiter, and place the second connecting device towards the central area. Weight blocks can be placed on the loading device as needed to increase the load, so that the fixing device rotates inwards through the rotating disc, thereby enabling the patient's foot to achieve an "in-toe" position.
