[0028] like Figures 1 to 5As shown, a headrest positioning device for examination includes: a testing machine 1, with an examination bed 101 on one side of the testing machine 1; a support member 2, disposed on the outside of the testing machine 1, for providing support to the patient; and a positioning mechanism, disposed on the outside of the support member 2, for providing support to the patient's head. The positioning mechanism includes a support pad 3 and a clamping member 4. The support pad 3 is disposed on the outside of the support member 2 for providing support to the patient's head, and the clamping member 4 is disposed inside the support member 2 for limiting the position of the support pad 3. The support pad 3, in conjunction with the clamping member 4, positions the patient's head. Specifically, when an examination is required, the clamping member 4 first fixes the support pad 3 to prevent the support pad 3 from shifting during use, thereby positioning the patient's head during use and facilitating rapid examination of the patient's head by the testing machine 1. A control block is provided at the bottom of the examination bed 101. During the process, the position and angle of the support plate 201 can be adjusted according to needs, so as to cooperate with the detection machine 1 to examine the patient in different positions. The top of the examination bed 101 is also equipped with a sponge pad to improve the patient's comfort. The support pad 3 is made of sponge material to ensure support for the patient while improving the patient's experience during use. The support pad 3 has a positioning groove on the outside to guide the position of the patient's head during use, ensuring that the patient can accurately place the head in the middle of the detection machine 1. There are no restrictions on the shape of the support pad 3, which can be square or round, etc. During use, the detection machine 1 can digitize the two X-ray images taken before and after the injection of contrast agent and input them into the image computer. Then, through the subtraction, enhancement and re-imaging process, a clear pure vascular image is obtained, and the vascular image is displayed in real time. The detection machine 1 is existing technology and will not be explained in detail here.

[0029] like Figures 1 to 5 As shown, the support member 2 includes a support plate 201, a support seat on the outer side of the support plate 201, a groove 202 inside the support plate 201, and the groove 202 penetrates one side of the support plate 201. A first guide groove 203 and a second guide groove 204 are provided on the outer side of the support plate 201. There are multiple second guide grooves 204, which are distributed on both sides of the first guide groove 203. The first guide groove 203, the second guide groove 204 and the groove 202 are connected. A limiting plate 205 is also provided on the outer side of the support plate 201. Specifically, the support plate 201 is connected to the inspection bed 101 through a mounting bracket 208. The mounting bracket 208 and the inspection bed 101 can be connected by plastic buckles or plastic bolts. The limiting plate 205 blocks the position of the support pad 3 during use to prevent the support pad 3 from separating from the inspection machine 1 during use.

[0030] like Figures 1 to 5As shown, a baffle 206 is provided at the opening end of the groove 202. Specifically, during use, the baffle 206 blocks the clamping part 4 to prevent the clamping part 4 from directly contacting the air. The baffle 206 and the support plate 201 can be connected by plastic buckles or plastic bolts, which facilitates the adjustment and maintenance of the clamping part 4 during use.

[0031] like Figures 1 to 5 As shown, the clamping member 4 includes an adjusting block 406, which slides inside the first guide groove 203. Multiple connecting ropes 402 are provided on the outer side of the adjusting block 406, each corresponding to a second guide groove 204. A first pulley 404 and a second pulley 405 are respectively provided on the outer side of each connecting rope 402, and the first pulley 404 and the second pulley 405 are connected to the support plate 201. A sliding block 401 is provided at the end of each connecting rope 402, which slides inside the second guide groove 204. A connecting plate 403 is provided on the outer side of the sliding block 401, and an abutment plate 407 is provided on the outer side of the adjusting block 406. Specifically, when fixing the position of the support pad 3, the support pad 3 to be fixed is first placed between the connecting plates 403, and then the abutment plate 407, the adjusting block 406, and the connecting ropes 402 work together to move the support pad 3. The sliding block 401 and the connecting plate 403 move towards each other. During the movement of the connecting plate 403, the support pad 3 is clamped. While the abutment plate 407 moves, it pushes the support pad 3 against the limiting plate 205, thereby positioning the support pad 3 and ensuring that the patient's head can be accurately placed in the middle of the support plate 201 during the examination. The connecting rope 402 can slide inside the adjusting block 406. During use, the position of the abutment plate 407 and the sliding block 401 can be pre-adjusted by pulling the connecting rope 402. The connecting plate 403 and the sliding block 401 can be connected by plastic buckles or plastic bolts. The first pulley 404 and the second pulley 405 guide the connecting rope 402, so that the sliding block 401 moves towards each other as the adjusting block 406 pushes the support pad 3.

[0032] like Figures 1 to 5 As shown, the sliding block 401, the first pulley 404, the connecting rope 402, the second pulley 405, and the abutment plate 407 are all made of plastic. Specifically, the plastic sliding block 401, the first pulley 404, the connecting rope 402, the second pulley 405, and the abutment plate 407 are designed to avoid interfering with the inspection machine 1 during use, ensuring the imaging effect of the inspection machine 1 during use.

[0033] like Figures 1 to 5As shown, the support plate 201 has multiple fixing grooves 207 on its outer side, and the fixing grooves 207 are arranged in a straight line. The fixing grooves 207 are equipped with connecting rods, and the connecting rods are connected to the connecting plate 403. Specifically, during use, the connecting rods cooperate with the fixing grooves 207 to limit the position of the connecting plate 403 after adjustment, so as to prevent the connecting plate 403 from moving during use. The connecting rods and fixing grooves 207 are connected by slots or threads to ensure the stability of the connection between the connecting rods and fixing grooves 207.
