Abstract
Description
Technical Field
[0001] The utility model relates to an early diagnosis device for identifying osteoporosis in combination with clinical CT. Background Art
[0002] Osteoporosis is a systemic bone disease characterized by decreased bone mass, damaged bone microstructure, increased bone brittleness, and susceptibility to fractures. With the aging of my country's population, the prevention and treatment of osteoporosis has become a serious social problem. The disease often has no obvious clinical manifestations in the early stages, so it is easy to be neglected. As the disease progresses, bone mass gradually decreases and bone microstructure is damaged, which in turn causes pain and spinal deformity. However, some patients still have no corresponding clinical symptoms and are only diagnosed after brittle fractures occur. Therefore, early diagnosis of osteoporosis is crucial.
[0003] Measuring bone density is the main means of diagnosing osteoporosis. There are two main methods for measuring bone density, namely dual-energy X-ray absorptiometry (DXA) and quantitative CT (QCT). At present, the diagnosis of osteoporosis is basically that the patient goes to the hospital for follow-up measurement, and then the diagnosis is made based on the measurement results. Since the measurement indicators of osteoporosis are related to the patient's age, gender, weight, and height, a single follow-up cannot accurately grasp the development of osteoporosis, and then make a 100% accurate early diagnosis of osteoporosis. Due to individual differences in some patients and the lack of corresponding clinical symptoms, it is easy to miss the diagnosis. Utility Model Content
[0004] The utility model aims to provide an early diagnosis device for identifying osteoporosis by combining clinical CT. The device organically combines clinical routine CT with follow-up CT to facilitate early diagnosis of osteoporosis.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0014] 1. Since the scanning range of different types of clinical CT (lung CT, abdominal CT, lumbar CT, etc.) generally includes the L1 vertebra, L1 is the most commonly used vertebral CT value measurement segment, and L1 is generally the first vertebra without ribs, which is easy to identify. Therefore, conventional clinical CT (such as lung CT, abdominal CT, lumbar CT, etc.) can be used for diagnosis or auxiliary diagnosis of osteoporosis. In particular, the utility model combines the completed conventional clinical CT and follow-up CT. Through comparison, it can effectively avoid the missed diagnosis of osteoporosis and understand the development of osteoporosis;
[0015] 2. The utility model has the advantages of adjusting the scanning position and reducing pain. The patient can lie flat for scanning examination through the bed board and the pillow. When lying flat, the patient can put his legs on the leg positioning plate, and the patient can be scanned and examined by the osteoporosis detector. The motor drives the threaded rod to rotate, and the bed board and all the structures on the bed board are driven to move left or right as a whole through the threaded sleeve and the movable block to fine-tune the scanning examination position. The patient does not need to move his body, thereby reducing the occurrence of pain in the patient's body caused by body movement, which is convenient for people to use;
[0016] 3. The utility model can ensure the normal operation of the movable block by setting the movable groove, can limit the threaded sleeve by setting the first slider and the first sliding groove, and can protect the motor by setting the protective shell; BRIEF DESCRIPTION OF THE DRAWINGS
