[0061] Example 1

[0062] Please see Figure 1-3 Specifically, in the embodiment of this cervical spine lateral radiography positioning aid, the cervical spine lateral radiography positioning aid provided in this application specifically includes a base plate 1 and a pair of pull rope adjustment mechanisms 2. The pair of pull rope adjustment mechanisms 2 are spaced apart on the base plate 1, forming a standing area between the pair of pull rope adjustment mechanisms 2. Each pull rope adjustment mechanism 2 includes a housing 21, a length adjustment component 22, and an elastic rope 23. The housing 21 is fixed to the base plate 1 and has an accommodating space inside. A through hole 211 is provided at the top of the housing 21. The length adjustment component 22 is disposed in the accommodating space of the housing 21 and is rotatably connected to the housing 21. One end of the elastic rope 23 is fixedly connected to the length adjustment component 22, and the other end of the elastic rope 23 extends out of the through hole 211 of the housing 21 and is located outside the housing 21.

[0063] Specifically, this utility model embodiment provides a cervical spine lateral radiography positioning assistance device, including a base plate 1 and a pair of pull rope adjustment mechanisms 2. The pair of pull rope adjustment mechanisms 2 are spaced apart on the base plate 1, forming a standing area between them. The patient can stand in this standing area, with each hand holding one pull rope adjustment mechanism 2 to apply tension to the patient's shoulders and prevent shoulder shrugging. Each pull rope adjustment mechanism 2 includes a housing 21, a length adjustment component 22, and an elastic rope 23. The housing 21 is fixed to the base plate 1 and has an accommodating space inside. A through hole 211 is provided at the top of the housing 21. The adjustment component 22 is disposed within the accommodating space, and the length adjustment component 22 is rotatably connected to the housing 21. One end of the elastic rope 23 is fixedly connected to the length adjustment component 22, and the other end of the elastic rope 23 extends out of the through hole 211 of the housing 21 and is located outside the housing 21. When the patient stands on the base plate 1 and holds an elastic rope 23 in each hand, the length of the elastic rope 23 can be adjusted by the length adjustment component 22 so that the elastic rope 23 is in a stretched state when the patient holds the elastic rope 23, so as to form a downward pulling force on the patient's hands. This allows the patient to maintain a drooping shoulder position when taking lateral radiographs, thereby ensuring the accuracy of the examination results and avoiding misdiagnosis and missed diagnosis.

[0064] In one possible implementation, each pull cord adjustment mechanism 2 further includes a limiting component 24, which is movably disposed within the accommodating space of the housing 21 and movably connected to the length adjustment component 22, so as to limit the rotation direction of the length adjustment component 22 by means of the limiting component 24.

[0065] In one possible implementation, the length adjustment assembly 22 includes a pivot 221, a ratchet 222, and a crank 223. The pivot 221 is disposed within the accommodating space of the housing 21, and both ends of the pivot 221 are rotatably connected to the inner sidewall of the housing 21. One end of the elastic cord 23 is fixed to the pivot 221, and the other end of the elastic cord 23 extends out from the through hole 211 of the housing 21 after being wrapped around the pivot 221. The ratchet 222 is fixed to the pivot 221. The crank 223 includes a fixing part and a hand-held part. One end of the fixing part extends into the housing 21 and is fixedly connected to one end of the pivot 221 and rotatably connected to the housing 21. The hand-held part is fixed to the other end of the fixing part and is located outside the housing 21.

[0066] Specifically, the user can rotate the crank handle 223 to drive the rotating shaft 221 and ratchet 222 to rotate, thereby releasing and shortening the elastic rope 23 wrapped on the rotating shaft 221. The limiting component 24 contacts the ratchet 222 to limit the unidirectional rotation of the ratchet 222.

[0067] In one possible implementation, a limiting post 212 is provided laterally on the inner wall of the first side of the housing 21. The limiting post 212 has a shaft groove. A circular hole is provided through the second side of the housing 21 at the corresponding position of the shaft groove. The first side and the second side are arranged opposite to each other and parallel to each other. One end of the limiting component 24 is movably disposed in the shaft groove, and the other end of the limiting component 24 extends out from the circular hole and is movably disposed in the circular hole.

[0068] Furthermore, the limiting assembly 24 includes a connecting shaft 241, a pawl 242, a spring 243, and a spring plate 244. One end of the connecting shaft 241 is movably disposed in the shaft groove, and the other end of the connecting shaft 241 extends out of the circular hole and is located outside the housing 21. The pawl 242 is rotatably connected to the connecting shaft 241 and contacts the ratchet 222. The spring 243 is sleeved on the connecting shaft 241, one end of the spring 243 is fixed to the end of the shaft groove, and the other end of the spring 243 is fixed to the pawl 242. One end of the spring plate 244 is fixedly connected to the pawl 242, and the other end of the spring plate 244 is fixedly connected to the inner sidewall of the housing 21.

[0069] That is, the distance from the pawl 242 to the end of the connecting shaft 241 is less than the distance from the pawl 242 to the bottom of the shaft groove, so that the connecting shaft 241 has a pressing movement space.

[0070] In one possible implementation, the distance between one end of the connecting shaft 241 and the limiting block 245 is less than the distance between the bottom of the shaft groove and the limiting block 245. That is, the distance between the pawl 242 and the end of the connecting shaft 241 is less than the distance between the pawl 242 and the bottom of the shaft groove. This allows for a pressing movement space between one end of the connecting shaft 241 and the shaft groove in the unpressed natural state. When the connecting shaft 241 is pressed and pressed into the shaft groove, the pawl 242 is just separated from the ratchet 222, thereby releasing the unidirectional rotation restriction of the ratchet 222. At this time, the user can rotate the shaft 221 in the opposite direction through the crank 223 to release the elastic rope 23.

[0071] In one possible implementation, the pawl 242 includes a rotating connecting portion and a limiting abutment portion. The limiting abutment portion is fixedly connected to the outer wall of the rotating connecting portion and rotatably sleeved on the connecting shaft 241 via the rotating connecting portion. The limiting abutment portion abuts against the teeth of the ratchet 222. A spring plate 244 is fixedly connected to the limiting abutment portion, thereby limiting the pawl 242's unidirectional rotation through the spring plate 244. The spring plate 244 is a bending mechanism, used to limit the pawl 242, and it can only compress and not stretch, thus enabling... Figure 2 The ratchet 222 can only rotate counterclockwise under the limiting action of the pawl 242.

[0072] Furthermore, the limiting component 24 includes a limiting block 245, which is fixed to the other end of the connecting shaft 241 near the end and located inside the housing 21. The outer diameter of the limiting block is larger than the inner diameter of the circular hole. Under the elastic force of the spring 243, the limiting block 245 abuts against the inner wall of the circular hole to limit the position of the connecting shaft 241.

[0073] Furthermore, the spring 243 is in a compressed state to provide an outward elastic thrust to the connecting shaft 241.

[0074] Specifically, such as Figure 2-3 As shown, by movably setting the connecting shaft 241 within the laterally positioned limiting post 212, the connecting shaft 241 can move relative to the limiting post 212. A spring 243 is provided between the pawl 242 fixed on the connecting shaft 241 and the limiting post 212, and the spring 243 is in a compressed state. The elastic thrust of the spring 243 pushes the limiting block 245 at the other end of the connecting shaft 241 against the inner wall of the housing 21. At the same time, the other end of the connecting shaft 241 extends out from the round hole, and the user can press the extended connecting shaft 241 so that the connecting shaft 241 can move in the direction close to the bottom of the shaft groove, thereby causing the pawl 242 to leave the ratchet 222, so as to release the pawl 242's restriction on the unidirectional rotation of the ratchet 222.

[0075] In practical use, the crank handle 223 can be turned to drive the rotating shaft 221 to rotate. At this time, because the pawl 242 is in contact with the ratchet 222, based on the mechanical linkage between the pawl 242 and the ratchet 222, the crank handle 223 can only drive the rotating shaft 221 to rotate in one direction. Figure 2 As shown, the rotating shaft 221 can be driven to rotate counterclockwise, so that the elastic rope 23 is wrapped more around the rotating shaft 221 to shorten the length of the elastic rope 23; when the connecting shaft 241 is pressed to move the pawl 242 away from the ratchet 222, thereby releasing the restriction effect of the pawl 242 on the ratchet 222, the elastic rope 23 can be released by rotating the crank 223 in the opposite direction.

[0076] In one possible implementation, each pull cord adjustment mechanism 2 further includes a grip 25, which is fixed to the other end of the elastic cord 23.

[0077] Furthermore, the grip 25 includes a connecting ring 251 and a handle 252. The other end of the elastic cord 23 is fixed to the connecting ring 251 at a distance from the handle 252 so that the user can grip the handle 252. A silicone layer can be provided on the handle 252 to improve grip comfort and friction.
