[0002] The hip joint is composed of the femoral head and the acetabulum, and is a ball-and-socket joint. Only the lunate surface in the acetabulum is covered with articular cartilage, and the acetabular fossa is filled with fat, also known as the Haversian gland, which can be squeezed out or inhaled as the intra-articular pressure increases or decreases to maintain the balance of the intra-articular pressure. In order to facilitate the magnetic resonance scanning of the hip joint, the hip joint angle needs to be positioned before this, so a locator is needed. The existing locator only has the effect of positioning the hip joint angle, but it is not convenient to measure the hip joint angle, so there are limitations in use. Based on this, it is necessary to provide a locator that can both locate the hip joint angle and measure it at the same time to enhance practicality. In addition, the existing locator is inconvenient to wear, so it is inconvenient to use. Based on this, it is necessary to provide a locator that is easy to wear and use and improves ease of use.

[0020] See also Figure 1-3 , the utility model provides a magnetic resonance scanning hip joint angle locator, comprising a fixing component 100 and a positioning component 200;

[0021] The fixing assembly 100 includes a waist belt 101, a first Velcro 102 and a second Velcro 103 are sewn on the side surface of one end of the waist belt 101, and the other end of the waist belt 101 is fixedly connected to a limit buckle rod 104;

[0022] The positioning assembly 200 includes two mounting blocks 201 sleeved on the side surfaces of the belt 101, and the interiors of the two mounting blocks 201 are rotatably connected with positioning blocks 202. The surfaces of the positioning blocks 202 are provided with mating grooves 203. The side surfaces of the mounting blocks 201 are fixedly connected with scale flanges 204, and the upper ends of the positioning blocks 202 are fixedly connected with pointers 205.

[0023] In a specific embodiment, the fixing component 100 cooperates with the positioning component 200 to not only locate the patient's hip joint, but also measure the angle of the hip joint, thereby enhancing the practicality of the positioner. In addition, through the cooperation of the above structures, not only can the positioner and the hip of patients with different waist circumferences be quickly installed, thereby improving the convenience and versatility of use, but also the position of the positioning component 200 and the contact degree with the hip joint can be adjusted, thereby improving the accuracy of angle measurement. When in use, first wrap the belt 101 around the patient's hip, then pass one end of the belt 101 through the sliding sleeve 231 and the limiting buckle rod 104, and adhere the first Velcro 102 and the second Velcro 103 to each other, so that the fixing component 100 and the positioning component 2 00 and the patient's hip. In addition, by controlling the length of the waist belt 101 passing through the limiting buckle rod 104, the contact degree between the positioning block 202 and the patient's hip can be adjusted at the mutually bonded portion of the first Velcro 102 and the second Velcro 103. Finally, by controlling the sliding sleeve 231 to move along the waist belt 101, the position of the positioning block 202 at the patient's hip joint can be adjusted, thereby improving the measurement accuracy. At this time, the patient's hip joints on both sides are fitted and snapped into the fitting groove 203, and the hip joint can be positioned by the positioning block 202. At the same time, the patient's hip joint can rotate with the positioning block 202. As the positioning block 202 rotates, the pointer 205 points to different positions of the scale flange 204, thereby being able to measure the angle of the hip joint, thereby enhancing the practicality of the locator.

[0024] See also Figure 2 A waist pad 111 is sewn on the side surface of the waist belt 101, and the waist pad 111 is made of pure cotton.

[0025] In a specific embodiment, the waist pad 111 made of pure cotton material can not only enhance the installation stability of the waist belt 101 and the patient's hips, but also protect the patient's lower back, thereby improving wearing comfort.

[0026] See also Figure 3 One end of the mounting block 201 is provided with a mounting groove 211 , and the positioning block 202 is rotatably mounted inside the mounting groove 211 .

[0029] In a specific embodiment, the limiting block 222 is clamped in the limiting groove 221, so that the positioning block 202 can be limited to prevent the positioning block 202 from rotating at will, thereby facilitating the measurement of the hip joint angle.

[0030] See also Figure 2 and Figure 3 One end of the mounting block 201 is fixedly connected with a sliding sleeve 231 , and the waist belt 101 is movably inserted into the inside of the waist belt 101 .

[0031] In a specific embodiment, the waist belt 101 is inserted into the interior of the sliding sleeve 231, so that the sliding sleeve 231 can be controlled to move along the waist belt 101, and then the position of the positioning block 202 can be adjusted to improve the measurement accuracy.

[0032] See also Figure 2 and Figure 3 The waist belt 101 is made of rubber, and the positioning block 202 is made of polyethylene. The side surfaces of the waist belt 101 and the positioning block 202 are both covered with cotton sleeves that fit the two.

[0033] In a specific embodiment, the rubber belt 101 is elastic, so it is easy to connect the positioner to the hips of patients with different waist circumferences, thereby enhancing versatility. The polyethylene positioning block 202 can enhance the positioning effect on the hip joint, and the presence of the cotton sleeve can improve the comfort of the belt 101 and the positioning block 202 when worn.

[0034] Working principle: When in use, firstly wrap the waist belt 101 around the patient's hip, then pass one end of the waist belt 101 through the sliding sleeve 231 and the limiting buckle rod 104 and adhere the first Velcro 102 and the second Velcro 103 to each other, so that the fixing component 100 and the positioning component 200 and the patient's hip can be installed. In addition, by controlling the length of the waist belt 101 passing through the limiting buckle rod 104 and the part where the first Velcro 102 and the second Velcro 103 are adhered to each other, the contact degree between the positioning block 202 and the patient's hip can be adjusted. Finally, By controlling the sliding sleeve 231 to move along the waist belt 101, the positioning block 202 can be adjusted at the patient's hip joint, thereby improving the measurement accuracy. At this time, the patient's hip joints on both sides are engaged and snapped into the engagement groove 203, and the hip joint can be positioned by the positioning block 202. At the same time, the patient's hip joint can rotate with the positioning block 202. As the positioning block 202 rotates, the pointer 205 points to different positions of the scale flange 204, so the angle of the hip joint can be measured, thereby enhancing the practicality of the locator.
