Technical Field
[0001] The utility model relates to the field of lumbar vertebra dynamic position film shooting, in particular to a lumbar vertebra dynamic position film shooting auxiliary device. Background Art
[0002] In the treatment of patients with degenerative lumbar spondylolisthesis and spinal stenosis, due to the lack of standardized images to evaluate the presence of abnormal lumbar motion and define lumbar instability, there is still a lot of controversy about whether the surgery should be decompression alone or fusion after decompression. At present, the more consistent view is that for patients with lumbar instability, fusion surgery is required at the same time as decompression. Therefore, patients with degenerative lumbar spondylolisthesis and spinal stenosis should have their lumbar stability evaluated before surgery, and auxiliary devices should be used when taking lumbar dynamic radiographs;
[0003] For example, the Chinese utility model (publication number CN214965746U) discloses an auxiliary device for taking lumbar dynamic radiographs, including a supporting structure, a lifting platform that can be raised and lowered, and an auxiliary body. This technical solution can significantly improve the detection rate of lumbar instability in patients with lumbar spondylolisthesis by taking lumbar hyperextension and hyperflexion radiographs with the help of auxiliary tools.
[0004] However, the above technical solution still has the following technical problems in actual use: no corresponding lifting device is provided, and after the patient in the above technical solution lies on his back on the auxiliary body, the waist is in a bent and stretched state, and after the shooting is completed, the patient needs to exert force on his waist to stand up. Patients who need to take lumbar dynamic radiographs generally have certain problems with their waists, which makes it difficult for them to stand up, reducing the practicality of the device and making it inconvenient to use.

The fixed plate 7 is connected to a reinforcing rod 12, and the reinforcing rod 12 is connected to the support plate 3.
[0021] The support plate, support frame and lifting device involved in this application are exactly the same as the prior art (Chinese utility model with publication number CN214965746U) proposed in the background technology, and the connection structure and lifting principle therebetween are also exactly the same. The lifting principle is the principle of a scissors-type lifting device, and its structure and working principle are prior art well known to practitioners in this field, and will not be repeated here.
[0022] The present invention cites the description of the lifting device in the prior art (Chinese utility model with publication number CN214965746U) and the appendix of the manual.

".
[0023] The specific implementation process is as follows:
[0024] The following is an example of taking a photo of a patient lying on his back. Figure 1 As shown, when in use, the height of the mounting plate and the auxiliary circular plate 4 is adjusted by lifting and lowering, and the servo motor 14 is operated to drive the storage roller 10 to rotate to loosen the tensioning rope 8, and then the protective pad is placed on the left side of the auxiliary circular plate 4, and the patient stands on the right side, and then lies down with the back close to the auxiliary circular plate 4. After lying down, the auxiliary pad 5 contacts the patient's back, and the two tensioning ropes 8 are respectively located on the front and back sides of the human body, and the contacting part can be controlled behind the chest so that the auxiliary pad 5 can better pull the patient, and then the shooting can be carried out. After the shooting is completed, the servo motor 14 is controlled to drive the storage roller 10 to rotate and retract the tensioning rope 8, and the tensioning rope 8 is retracted on the storage roller 10, thereby pulling the auxiliary pad 5 to move to the upper right, and then a pulling force is applied to the patient's back through the auxiliary pad 5, thereby assisting the patient to stand up quickly and easily. The same is true when lying down, so that the auxiliary pad 5 contacts the patient's chest. During this period, the patient can also hold the handle 13 to assist himself in standing.
[0025] The technical solution is provided with an auxiliary pad 5. When in use, the auxiliary pad 5 is placed on the patient's back or chest (depending on whether the patient is lying on his back or prone). The servo motor 14 drives the storage roller 10 to rotate to pull the auxiliary pad 5. The auxiliary pad 5 applies a pulling force to the patient, thereby assisting the patient to easily recover to a standing state, which greatly improves the stability of the device. The overall structure is simple and easy to use. A rotating roller 11 is provided in the groove 9, thereby reducing the wear between the tensioning rope 8 and the side wall of the sliding groove, thereby improving the service life and stability of the tensioning rope 8. The handle 13 is used to facilitate the patient to assist in regaining a standing state. The reinforcing rod 12 is used to improve the stability of the fixing plate 7, thereby improving the stability of the tensioning rope 8 in transferring garbage.
