Description

Technical Field

[0001] The invention relates to the technical field of fixing devices, in particular to a fixing device. Background Art

[0002] Whole-body bone imaging in nuclear medicine is used to screen whether cancer patients have bone metastasis and some benign lesions. Due to body position, most people's feet will be in an "outward eight" shape when standing upright or lying flat. In this body position, the tibia and fibula of the subject's bilateral lower limbs will overlap to a large extent during supine plane imaging, and the whole-body bone imaging results cannot clearly distinguish the location of the lesions in the two bones. If the subject is asked to actively maintain the "inward eight" body position, the subject's leg muscles need to remain contracted, which cannot be maintained for a long time and is prone to fatigue. In this way, changes in the position of the subject's lower limbs and feet during imaging may cause artifacts in the image, making it difficult to make a correct diagnosis.

[0003] Most of the existing fixation devices for nuclear medicine bone imaging fix the patient's feet on a special inclined board, and then use straps to restrain the feet. The help of both hands is required, the steps are cumbersome, and the help of both hands cannot be separated. The feet cannot be tilted and fixed in one step. Choosing the same fixation method and angle for different people will make some people feel uncomfortable, and the inspection efficiency is also low. Summary of the invention

[0004] In view of the problems that the prior art has low applicability and is inconvenient to use, the present invention provides a fixing device which has the advantages of high applicability and convenient use.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0007] Preferably, a semicircular turntable is provided on the front side of the fixing seat, a cylinder is provided on the front side of the connecting plate, and the front side of the cylinder is rotatably connected to the turntable.

[0008] Preferably, a groove is provided on the top of the first connecting device, and a second connecting device is placed in the groove. One end of the second connecting device is fixedly connected to a load-bearing device, and the other end of the second connecting device is rotatably connected to two plug pieces.

[0009] Preferably, the fixing device includes an outer shell, a third connecting device is arranged at the center of the front side surface of the outer shell, the outer shell and the third connecting device are fixedly connected, a movable groove is arranged at the center position of the third connecting device, a pusher is arranged in the movable groove, a fourth connecting device is fixedly connected to the rear side surface of the pusher, the device consisting of the fourth connecting device and the pusher is movably connected to the third connecting device, a threaded disk is fixedly connected to the back of the fourth connecting device, a limiter is fixedly connected to the back of the threaded disk, a limiter is fixedly connected to the back of the limiter, a rotating disk is rotatably connected to the back of the limiter, the rotating disk is fixedly connected to the front side surface of the first connecting device, and the third connecting device is slidably connected to the connecting disk.

[0010] Preferably, the shape of the limiter is an "I" shape, the second connecting device is arranged on the top of the limiter, and the limiter is movably connected to the second connecting device.

[0011] Preferably, sliding plates are provided on the left and right sides of the fixing device, the front end of the sliding plate is fixedly connected to a fixed square plate, the fixed square plate is slidably connected to the fixing device, the outer side of the sliding plate is provided with a fixed plate, the sliding plate and the fixed plate are slidably connected, the fixed plate is 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 fixed plate is fixedly connected to the connecting disk.

[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 on the top of the arc-shaped sliding block, and a limiting plate is arranged on the top of the middle connecting groove.

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

[0014] Nuclear medicine bone imaging 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 examination, it is usually necessary to fix the patient's foot at an angle. 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, it drives the threaded disk fixedly connected to the pusher to move forward. During the forward movement, the threaded disk drives the threaded rod to rotate on the rotating shaft through the threaded surface, thereby driving the sliding plate threadedly connected to the rotating shaft to move backward, and driving the fixed square plate fixedly connected to the sliding plate to move backward. The foot is fixed by the fixed square plate, instead of manual strapping, which is more convenient to use.

[0016] When the fixed square plate moves backward, the rotating disc arranged on its inner side surface will pass through the arc-shaped sliding block and reach the position of the middle connecting groove, and the foot will be further fixed by the connecting head. The sliding spring block can ensure the activity of the sixth connecting device to avoid jamming. The fixed disc and the sixth connecting device are connected to form a lever to transmit the movement state of the rotating disc to the position of the connecting head.

[0017] After fixation, the subject's feet need to be in an "inward-facing" position. At this time, there is a certain distance between the tibia and fibula of the bilateral lower limbs. The tibia and fibula are parallel in the whole-body bone plane imaging, and the positions of the tibia and fibula and the lesions can be easily distinguished. The second connecting device can be taken out, and the plug fixedly connected to the bottom of the second connecting device can be inserted into the limiter, and the second connecting device can be placed toward the center area. Weight blocks can be placed on the weight-bearing device as needed to increase the weight, so that the fixing device rotates inwardly through the rotating disk, so that the patient's feet can achieve the "inward-facing" position. When in use, the appropriate weight block can be selected according to the patient's body shape to achieve the "inward-facing" position. It is suitable for different people and can effectively improve the comfort of the patient.

[0018] Beneficial effects:

[0019] 1. This fixation device usually requires the patient's foot to be tilted and fixed during examination. When in use, the patient places the foot in the middle of the fixation device. After placement, the sole of the foot will push the pusher to move inward. During the inward movement of the pusher, it drives the threaded disk fixedly connected to the pusher to move forward. During the forward movement, the threaded disk drives the threaded rod to rotate on the rotating shaft through the threaded surface, thereby driving the sliding plate threadedly connected to the rotating shaft to move backward, and driving the fixed square plate fixedly connected to the sliding plate to move backward. The foot is fixed by the fixed square plate, which replaces manual strapping and is more convenient to use.

[0020] 2. In the process of the fixed square plate moving backward, the rotating disc arranged on the inner side of the fixing device will pass through the arc-shaped sliding block and reach the position of the middle connecting groove, and the foot will be further fixed by the connecting head. The sliding spring block can ensure the activity of the sixth connecting device to avoid jamming. The fixed disc and the sixth connecting device are connected to form a lever to transmit the movement state of the rotating disc to the position of the connecting head, thereby replacing manual fixation and improving inspection efficiency.

[0021] 3. The fixing device is manufactured by taking out the second connecting device, inserting the plug fixedly connected to the bottom of the second connecting device into the limiter, and placing the second connecting device toward the center area. A weight block can be placed on the weight-bearing device as needed to increase the weight, so that the fixing device rotates inwards through the rotating disk, thereby enabling the patient's feet to achieve an "inward eight" position. When in use, a suitable weight block can be selected according to the patient's body shape to achieve the "inward eight" position. This is suitable for different groups of people and can effectively improve the patient's comfort. BRIEF DESCRIPTION OF THE DRAWINGS
