Description

Technical Field

[0001] The utility model belongs to the technical field of medical examination equipment, and in particular relates to a fixing device for nuclear medicine imaging. Background Art

[0002] Nuclear medicine whole body imaging is a method of examination that introduces radioactive nuclide-labeled bone-loving drugs into the human body, and then uses the corresponding instruments of the nuclear medicine department to detect the radiation emitted by the radioactive drugs in the human body. After computer processing, the whole body bone phenomenon is formed, and the whole body bone phenomenon is used for diagnosis. It is usually used to screen patients for bone metastasis and some benign lesions. During the whole body imaging of nuclear medicine, due to the body position, the position of the two feet of most people when standing upright and lying flat presents a habitual "outward eight" position. In this position, the tibia and fibula of the subject's bilateral lower limbs overlap to a large extent during the supine plane imaging, resulting in the whole body imaging results. The results cannot clearly distinguish the two bone lesion locations. Generally, the subject's feet are required to be in the "inward eight" position. At this time, there is a certain distance between the tibia and fibula of the bilateral lower limbs. The whole body bone plane imaging shows that the tibia and fibula are parallel, and the location of the tibia and fibula and the lesion can be easily distinguished. However, when the patient actively maintains the "inward eight" position for a long time, it is easy to cause leg soreness and fatigue.

[0003] After searching, it is found that the Chinese publicly authorized patent "A fixing device for nuclear medicine bone imaging" with the publication number "CN216675764U" includes a base plate, a fixing seat is fixedly installed on one end of the upper surface of the base plate, a support column is fixedly installed on the upper surface of the fixing seat, the base plate is installed on one side of the fixing seat, a protective plate is installed on one side of the base plate, and an elastic strap is installed on the side of the base plate; the patent installs the base plate on one side of the fixing seat, and then through the action of two groups of threaded rods, the bottom ends of the two groups of base plates are moved to both sides or to the middle at the same time, so that the patient's feet are in an "inward eight" position, and the feet can be supported for a long time to prevent the patient's foot position from changing due to fatigue during the autonomous control process, thereby making the imaging unclear and affecting the doctor's diagnosis.

[0004] However, in the above case, the fixation device used for nuclear medicine bone imaging had the following problems when in use:

[0005] 1. Since the midsole plate rotates with the fixed block, the spherical groove and the spherical rod as the center, the above device cannot drive the bottom end of the bottom plate to rotate through the adjustment mechanism. When the patient lies on his back on the bottom plate for nuclear medicine imaging examination, the bottom plate cannot be rotated to drive the patient's feet to be fixed in the pigeon-toed position, which affects the doctor's diagnosis;

[0006] (2) At the same time, the device is not designed with a support component for the calf. Therefore, when the patient lies on his back for examination, after the foot acts on the bottom plate, the back of the calf is suspended in the air, which can easily cause discomfort to the patient during a long examination.

[0007] Therefore, the utility model provides a fixing device for nuclear medicine imaging to solve the above problems. Utility Model Content

[0008] 1. Technical issues to be resolved

At this time, the patient puts both feet into the limit sleeves on the adjustment plate respectively. Then the medical staff drives the two threaded sleeves to move in opposite directions by rotating the bidirectional screw. Then the threaded sleeve drives the bottom end of the adjustment plate to rotate around the second rotating rod through the first rotating rod. At the same time, the adjustment plate will drive the movable sleeve to slide downward on the surface of the fixed rod through the second rotating rod until the patient's feet are in the pigeon-toed position. The pigeon-toed position of the patient's feet can be adjusted and fixed, which effectively ensures the accuracy of the nuclear medicine imaging examination.

[0017] As a preferred solution of the fixing device for nuclear medicine imaging described in the utility model:

[0018] The support assembly includes a support seat, the bottom of the support seat is connected to a slider via a connecting piece, the slider is slidably set in a slide groove on the bottom plate and slides along the length direction of the slide groove; a protective pad is provided on the inner wall of the support seat, and the cross-section of the protective pad is an arc-shaped structure.

[0019] Based on the above technical features: when the patient lies on his back, the two calves are respectively placed on the protective pads in the two support seats to improve the comfort of the patient's legs during nuclear medicine imaging examinations. At the same time, the patient's feet will be placed in the limiting sleeves during adjustment. When the adjustment plate is adjusted, the adjustment plate will drive the patient's feet and calves to move synchronously through the limiting sleeves, thereby playing a role of dynamic support and protection.

Then the medical staff drives the two threaded sleeves to move in opposite directions by rotating the bidirectional screw. Then the threaded sleeve drives the bottom end of the adjustment plate to rotate around the second rotation rod through the first rotation rod. At the same time, the adjustment plate drives the movable sleeve to slide downward on the surface of the fixed rod through the second rotation rod until the patient's feet are in the pigeon-toed position. Compared with the comparative case, the adjustment plate in this device can be adjusted normally, so that the patient's feet are fixed in the pigeon-toed position when undergoing nuclear medicine imaging examination, which can effectively ensure the accuracy of nuclear medicine imaging examination;

[0024] 2. Through the setting of the support component, when the patient lies on his back, his two calves are placed on the protective pads in the two support seats respectively, so as to improve the comfort of the patient's legs during nuclear medicine imaging examinations. At this time, his feet will be placed in the limiting sleeves. When the adjustment plate is adjusted, the adjustment plate will drive the patient's feet and calves to move through the limiting sleeves. Subsequently, when the nuclear medicine imaging examination is performed, the patient's calves will drive the slider to slide on the inner wall of the slide groove through the support seat until it is adjusted to a suitable position, thereby facilitating the adjustment of the position of the support seat and improving the practicality of the device; the purpose of positioning the patient's feet for examination posture and ensuring the patient's examination comfort is achieved.
