[0002] Knee joint ultrasound examination is a commonly used medical imaging diagnostic method, mainly based on the considerations of improving examination accuracy, reducing the impact of patient movement on image quality, and improving patient comfort. With the continuous improvement of ultrasound instruments and imaging technology, high-frequency ultrasound plays an increasingly important role in the diagnosis of superficial soft tissue diseases. In particular, in recent years, high-resolution musculoskeletal ultrasound has been widely used in the diagnosis of knee joint diseases and has become an important imaging examination method.

Two limit plates 247 are symmetrically fixedly connected to the first support plate 101 and the first adjustment plate 103 respectively, and the limit plates 247 are provided with a socket 248 that cooperates with the insert block 246.

[0059] When the rectangular frame 232 needs to be installed and fixed, the rectangular frame 232 is inserted into the rectangular opening 231, and then the rotating block 242 is twisted. The rotating block 242 drives the worm 241 to rotate, and the worm 241 drives the worm wheel 240 and the connecting rod 239 to rotate. The connecting rod 239 rotates to drive the third gear 243. The third gear 243 drives the two rack plates 244 to move in the same direction in the rectangular shell 238. The two rack plates 244 respectively drive the connecting rod 245 to move inward, and the two connecting rods 245 respectively drive the insert block 246 to be inserted into the corresponding socket 248 on the limit plate 247, so as to install and fix the rectangular frame 232, which is convenient for heat dissipation of patients in different body positions.

[0060] like Figure 7 As shown, the inner wall of the ultrasonic track 216 is slidably connected with a T-shaped slider 250 , and the bottom end of the fixing plate 217 is fixedly connected to the T-shaped slider 250 .

[0061] By providing a T-shaped slider 250, when the fixed plate 217 is sliding, it can drive the T-shaped slider 250 to slide in the ultrasonic track 216 on the elastic strip 215. Through the cooperation between the T-shaped slider 250 and the ultrasonic track 216, the clamping assembly can be limited, so that the ultrasonic detection head is more stable during the movement.

[0062] like Fig.14 As shown, a long plate 251 is fixedly connected to the right end of the second adjustment plate 104 , and a coordinate scale 252 is provided on the long plate 251 .

[0063] By providing the long board 251, it is convenient for staff who are not familiar with the ultrasonic operation of the knee joint to perform precise operation according to the coordinate scale 252 under the remote guidance of a senior doctor, thereby improving the accuracy of diagnosis.

[0064] The working process of the technical solution of the present invention is as follows:

[0065] When in use, the patient's legs are passed through the middle part of the device so that the patient's knee joint is placed between the second support plate 102 and the second adjustment plate 104, and then the screw block 212 is twisted, and the screw block 212 drives the screw rod 211 to rotate in the first rectangular block 210, and the screw rod 211 is rotated into the threaded hole 214 on the second rectangular block 213, so that the patient's body position is in contact with the first arc-shaped sponge block 105 and the second arc-shaped sponge block 106, and the patient's body position is fixed; the first support plate 101, the second support plate 102 and the first adjustment plate 103, the second adjustment plate 104 are connected by the connecting membrane 209, and the patient's body position can also be restricted and protected.

[0066] Then, the handle 203 is pulled, and the handle 203 drives the sliding block 202 to slide in the rectangular sleeve 201, the first spring 204 is compressed, the sliding block 202 drives the connecting block 205 to slide, and the connecting block 205 drives the insertion rod 206 to leave the socket 208 on the circular plate 207; then, the knob 111 is turned, the knob 111 drives the rotating shaft 110 to rotate, the rotating shaft 110 drives the socket 208 and the second gear 112 to rotate, the second gear 112 drives the first gear 109 and the rotating rod 107 to rotate, and the rotating rod 107 drives the first adjusting Plate 103 rotates to adjust the angle of the first adjustment plate 103. When the first adjustment plate 103 is adjusted to a position suitable for ultrasonic examination of the patient's knee joint, the handle 203 is released, the first spring 204 rebounds, and the sliding block 202 drives the connecting block 205 and the insertion rod 206, so that the insertion rod 206 is inserted into the socket 208 on the circular plate 207 to limit the rotating shaft 110 and prevent the rotating shaft 110 from rotating at will. Staff who are not familiar with knee joint ultrasonic operation can perform precise operations through the coordinate scale 252 to improve the accuracy of diagnosis.

[0067] Then, place the ultrasonic detection head on the top of the fixed plate 217, turn the rotary block 220, the rotary block 220 drives the bidirectional threaded rod 219 to rotate, the bidirectional threaded rod 219 drives the two clamping plates 221 and the rubber pad 222 to approach each other along the length direction of the limit rod 223, clamp and fix the ultrasonic detection head, and then, pull the pull block 226, the pull block 226 drives the sliding rod 225 to slide on the connecting plate 224, the sliding rod 225 drives the circular plate 227 to slide, the second spring 228 is compressed, and the circular plate 227 drives the pin 229 to leave the slot 230 on the elastic strip 215, and then, slide the fixed plate 217, the fixed plate 217 drives the T-shaped slider 250 to slide in the ultrasonic track 216 on the elastic strip 215.

[0068] During the sliding process of the fixed plate 217, when the ultrasonic detection head is driven to slide to the position where an ultrasonic examination of the patient's body is required, the pull block 226 is released, the second spring 228 rebounds, and the circular plate 227 drives the pin 229 to be inserted into the slot 230 on the elastic strip 215 to fix the fixed plate 217, thereby facilitating the ultrasonic detection head to perform an ultrasonic examination of the patient's body position.

[0069] When the temperature is high and the patient's body needs to be cooled, the rectangular frame 232 is inserted into the rectangular opening 231, and then the rotating block 242 is turned, the rotating block 242 drives the worm 241 to rotate, the worm 241 drives the worm wheel 240 and the connecting rod 239 to rotate, the connecting rod 239 rotates and drives the third gear 243, the third gear 243 drives the two rack plates 244 to move in the same direction in the rectangular shell 238, the two rack plates 244 respectively drive the connecting rod 245 to move inward, and the two connecting rods 245 are connected to the inner side of the rectangular shell 238. 45 respectively drives the plug block 246 to be inserted into the socket 248 on the corresponding limit plate 247 to install and fix the rectangular frame 232, and then starts the motor 235, and the motor 235 drives the fan blade 236 to rotate. Through the rotation of the fan blade 236, the gas passes through the rectangular frame 232 into the first arc-shaped sponge block 105, and is discharged through the first arc-shaped sponge block 105 to dissipate heat for the patient's body position. The hot air can be discharged through the heat dissipation hole 249, which is convenient for dissipating heat for different patient positions.
