[0002] Knee muscle ultrasound technology is a method that uses ultrasound technology to evaluate and diagnose knee diseases and injuries. It has the advantages of being non-invasive, real-time and radiation-free. Knee muscle ultrasound examination allows doctors to observe the dynamic changes inside the joint when the patient performs specific movements (such as bending), thereby more accurately evaluating the functional status and potential abnormalities of the joint.

Tension springs are respectively arranged between the two first limiting shells 8 and the two second limiting shells 9 and the adjacent limiting frames 12, and the initial state of the tension spring is a stretched state. The upper side of the second sliding frame 10 is provided with equidistantly distributed limiting grooves, and the limiting frame 12 is limitedly matched with the equidistantly distributed limiting grooves on the upper side of the adjacent second sliding frame 10.

[0028] like Figure 2 and Figure 4 As shown, the adjustment mechanism 13 includes a first fixed shell 1301, the first fixed shell 1301 is fixedly connected to the ultrasonic probe 2, the first fixed shell 1301 is slidably connected to a sliding frame 1302, the right side of the sliding frame 1302 is fixedly connected to an extrusion frame 1303, the extrusion frame 1303 is made of soft rubber material, and is used to fit the skin while scraping off excess coupling agent, the ultrasonic probe 2 is fixedly connected to two second fixed shells 1304 distributed in front and back mirror images through a mounting block, the second fixed shell 1304 is used to store coupling agent, and the second fixed shell 1304 is connected to the first fixed shell 1301 through a pipeline.

[0029] like Figure 2 and Figure 4 As shown, two first piston rods 1305 distributed in front and back mirror images are fixedly connected to the left side of the sliding frame 1302, and the two first piston rods 1305 are both slidably connected to the first fixed shell 1301. The ultrasonic probe 2 is fixedly connected to two third fixed shells 1306 distributed in front and back mirror images through the mounting block. The third fixed shell 1306 is filled with a coupling agent for providing pressure. The first piston rod 1305 is slidably connected to the adjacent third fixed shell 1306, and a tension spring is arranged between the two. Flanges are arranged on the left sides of the second fixed shell 1304 and the third fixed shell 1306, and valves for manual control are arranged in the flanges of the two, and the flanges of the two are connected through pipelines.

[0030] like Figure 2 and Figure 5 As shown, the limiting and fixing mechanism 14 includes two limiting rings 1401 distributed in left and right mirror images, the two limiting rings 1401 are respectively fixed to the opposite sides of the two rotating rods 6, and the opposite sides of the two rotating frames 7 are slidably connected to the limiting rods 1402, the opposite sides of the two limiting rings 1401 are provided with limiting holes distributed in a circumferential array, the opposite sides of the two limiting rods 1402 are provided with inclined surfaces, the limiting holes distributed in the circumferential array on the limiting rings 1401 are matched with the inclined surfaces on the adjacent limiting rods 1402, a tension spring is provided between the limiting rod 1402 and the adjacent rotating frame 7, and the opposite sides of the two limiting rods 1402 are fixed with the first fixing plate 1403.

[0031] When it is necessary to use the device to perform ultrasonic diagnosis of the patient's knee joint, the user first lets the patient lie on the upper side of the medical bed 3, and passes the patient's legs through the left and right first fixing frames 11 respectively. Taking the left leg as an example, when the suitable fixing position of the left calf (that is, the position cannot be too close to the knee) moves to the right into the right front first fixing frame 11, the user controls the right front first fixing frame 11 to fix the left calf, and the patient continues to control the left leg to move to the right, and the patient's left leg drives the right front first fixing frame 11 and the right front second sliding frame 10 to move to the right, until the patient's knee joint moves to the rotating frame 7, the patient's left leg stops moving to the right, and under the tension of the tension spring between the right front limiting frame 12 and the adjacent second limiting shell 9, the limiting frame 12 is driven to move downward and limit the second sliding frame 10, and then the user controls the left front The second sliding frame 10 and the first fixed frame 11 on the left side move to the left until the first fixed frame 11 on the right front side moves to the left to a suitable fixed position (that is, the position cannot be too close to the knee), and the user controls the fixing device in the first fixed frame 11 on the left front side to fix the patient's thigh. At the same time, the tension spring between the left front side limiting frame 12 and the first limiting shell 8 drives the left front side limiting frame 12 to move downward and limit the second sliding frame 10 on the left front side. Then the user injects the coupling agent into the second fixed shell 1304 and the third fixed shell 1306 through the flanges on the rear sides of the second fixed shell 1304 and the third fixed shell 1306 respectively. At this time, the preparation steps are completed, and the first limiting shell 8 and the second limiting shell 9 are respectively cooperated with the adjacent second sliding frame 10 to adjust the fixing position, thereby increasing the scope of application of the device and improving the practicality of the device.

[0032] When performing ultrasound examination on the patient's knee joint, the following operations are required to prevent the coupling agent from being difficult to reach some narrow areas and affecting the ultrasound detection effect:

[0033] After the preparation steps are completed, the user holds the ultrasonic probe 2 to monitor the patient's knee joint (taking the user controlling the ultrasonic probe 2 to move downward as an example). During this process, the squeezing frame 1303 first contacts the patient's skin. As the user continues to control the ultrasonic probe 2 to move downward, the squeezing frame 1303 and the sliding frame 1302 are squeezed and move upward. The sliding frame 1302 drives the two first piston rods 1305 to move upward, and at the same time stretches the tension spring between the first piston rod 1305 and the adjacent third fixed shell 1306. The first piston rod 1305 moves upward and squeezes the coupling agent in the adjacent third fixed shell 1306 into the adjacent second fixed shell 1304 through the pipeline, and the coupling agent in the second fixed shell 1304 is squeezed and moves downward through the pipeline into the first fixed shell 1301. The coupling agent entering the first fixed shell 1301 is pressed between the surface of the ultrasonic probe 2 and the patient's skin. The gap is filled, and then the user controls the ultrasonic probe 2 to perform ultrasonic detection on the patient's knee joint. When the ultrasonic probe 2 moves close to the skin, the squeezing frame 1303 close to the skin synchronously scrapes off the coupling agent remaining on the skin, thereby facilitating the subsequent cleaning of the coupling agent. During the monitoring process, if it is necessary to detect the patient's joint gap, the ultrasonic probe 2 moves downward, and the squeezing frame 1303 stops moving downward due to the limitation of the bones on both sides, that is, the squeezing frame 1303 drives the sliding frame 1302, which is equivalent to the first fixed shell 1301 moving upward. The sliding frame 1302 cooperates with the first piston rod 1305 and drives the coupling agent to move into the first fixed shell 1301, thereby increasing the coupling agent pressure in the first fixed shell 1301, increasing the fitting area between the coupling agent and the patient's skin, and preventing the gap between the ultrasonic probe 2 and the patient's skin from affecting the ultrasonic detection result.

[0034] When testing the patient's knee joint, the patient is usually asked to perform a series of specific knee joint movements, such as flexing to a specified angle. If the patient's knee joint feels pain or discomfort at a certain angle, the patient may subconsciously straighten the knee joint to avoid pain, causing the patient's knee bending angle to change, thereby affecting the work efficiency during the ultrasonic testing process and prolonging the patient's discomfort during the examination. To solve the above problem, the following operations are required:

[0035] When the patient's knee joint needs to bend, the user controls the patient's leg to curl up (that is, the knee is deflected to a specified angle). During this process (taking the patient's left leg as an example), the patient's leg drives the adjacent second sliding frame 10 to swing through the adjacent first fixed frame 11, and the left and right second sliding frames 10 simultaneously drive the front first limiting shell 8 and the second limiting shell 9 to deflect, the first limiting shell 8 drives the rotating rod 6 to rotate, and the second limiting shell 9 drives the rotating frame 7 to rotate, at this time, the rotating rod 6 and the rotating frame 7 rotate relative to each other, and during this process, the rotating rod 6 drives the limiting ring 1401 to rotate, and the rotating frame 7 drives the limiting rod 1402 to rotate, the limiting ring 1401 and the limiting rod 1402 rotate relative to each other, and the limiting ring 1401 squeezes and drives the limiting rod 1402 to move forward, and at the same time stretches the tension spring between the limiting rod 1402 and the rotating frame 7 until the limiting rod 1402 moves to the next limiting hole of the limiting ring 1401, and the tension spring between the limiting rod 1402 and the rotating frame 7 drives the limiting rod 1402 to rotate. The positioning rod 1402 moves backward and limits again until the patient's knee bends to a specified angle. At this time, the angle adjustment is completed, and the limiting rod 1402 cooperates with the limiting ring 1401 to limit the angle to prevent the patient from affecting the detection process due to pain. The user controls the ultrasonic probe 2 to continue ultrasonic detection of the knee joint until the detection is completed. Then the user pulls the first fixing plate 1403, and the first fixing plate 1403 drives the limiting rod 1402 to move forward until the limiting rod 1402 loses the limit on the limiting ring 1401. At this time, the angle fixation is released, and the user controls the two first fixing frames 11 to release the fixation of the patient's legs. The user then controls the left and right second sliding frames 10 to drive the left and right first fixing frames 11 to reset, and the patient pulls out his legs. At this time, the use of the device is completed, and the first limiting shell 8 and the second limiting shell 9 cooperate to fix the patient's knee joint angle to prevent the patient from affecting the detection result due to pain during the detection, thereby improving the accuracy of ultrasonic detection of the device.

[0040] In order to make the patient's leg fixation state automatically controlled by the patient's will (i.e., release the knee angle fixation when the pain becomes unbearable), the following operations are required:

[0041] When the user controls the first fixing frame 11 to fix the patient's legs (taking the patient's left calf as an example), the user controls the telescopic end of the first electric push rod 1504 to retract, and the first electric push rod 1504 drives the second fixing plate 1505 and the two second piston rods 1503 to move to the right, and the second piston rod 1503 squeezes and drives the air in the adjacent air storage shell 1502 to flow into the adjacent fixing tube 1507, and the gas flows into the adjacent air bag group 1506 after passing through the one-way valve in the fixing tube 1507, and the air flow is injected into the adjacent upper and lower air bag groups 1506 to expand and fix the patient's calf at the same time, until the upper and lower air bag groups 1506 have fixed the patient's calf, and the user controls the telescopic end of the first electric push rod 1504 to stop moving, at which time the patient's left calf is fixed.

As the second piston rod 1503 gradually moves to the right, the pressure in the air storage shell 1502 and the regulating shell 1514 increases synchronously, and the air drives the fourth piston rod 1515 to move upward, and squeezes the spring between the fourth piston rod 1515 and the regulating shell 1514, and the fourth piston rod 1515 drives the adjacent third fixed plate 1516 to move upward. , the third fixed plate 1516 drives the adjacent limit block 1517 to move upward synchronously, and stretches the tension spring between the fourth fixed shell 1508 and the sliding plate 1510. During the upward movement of the limit block 1517, the upper side of the limit block 1517 contacts and squeezes the adjacent limit groove on the second fixed frame 1518, and at the same time squeezes the spring between the adjacent limit block 1517 and the sliding plate 1510 until the limit block 1517 stops moving upward. In this process, the spring between the limit block 1517 and the sliding plate 1510 drives the limit block 1517 to move back and forth continuously and The sliding plate 1510 is limited by the adjacent limiting groove on the second fixing frame 1518, and when the sliding plate 1510 moves upward, the tension spring between the sliding plate 1510 and the fourth fixing shell 1508 is stretched, thereby enhancing the squeezing of the third piston rod 1509 by the sliding plate 1510 through the second fixing frame 1518. When air is injected into the airbag group 1506, since the fourth fixing shell 1508 is connected to the airbag group 1506 through a pipeline, the airbag group 1506 and the fourth fixing shell 1508 are in the same pressure environment. If the airbag group 1506 expands more (that is, the thinner the fixed part of the patient's leg is), the airbag group 1506 will be more likely to expand. ), the greater the pressure in the fourth fixed shell 1508, and at this time, the squeezing of the third piston rod 1509 by the sliding plate 1510 through the second fixed frame 1518 increases year-on-year (that is, the pressure in the fourth fixed shell 1508 is proportional to the squeezing force of the third piston rod 1509 on the fourth fixed shell 1508), and the blocking force between the third piston rod 1509 and the fourth fixed shell 1508 is proportionally adjusted according to the pressure in the airbag group 1506 through the cooperation of the limit block 1517 and the second fixed frame 1518, thereby ensuring that the status of legs of different thicknesses can be monitored.

[0043] If the patient's pain is unbearable, the patient will stretch his legs consciously or passively. During the stretching process, the patient's calf squeezes the upper airbag group 1506, and the airbag group 1506 is squeezed to increase its internal pressure. When the internal pressure increases, the third piston rod 1509 is driven by the air pressure to gradually move upward, and at the same time, the spring between the sliding plate 1510 and the fourth fixed shell 1508 is stretched until the upper end of the third piston rod 1509 contacts and squeezes the button on the second fixed frame 1511. After the button on the second fixed frame 1511 is squeezed, the telescopic end of the second electric push rod 1512 is controlled to extend, and the telescopic end of the second electric push rod 1512 squeezes and drives the first fixed plate 1403 to move forward, and the first fixed plate 1403 drives the limit rod 1402 to move forward until the limit ring 1401 fails. The limit rod 1402 is removed, and the patient's legs can move freely, thereby relieving the patient's pain. After the patient's pain is relieved, the user repeats the above-mentioned detection steps to continue detecting the patient's knee joint until the patient's knee joint detection is completed. The user controls the telescopic end of the first electric push rod 1504 to extend and reset. The telescopic end of the first electric push rod 1504 drives the two air bag groups 1506 to reset through the two air storage shells 1502, thereby losing the fixation of the patient's legs, and the air storage shells 1502 synchronously drive other parts to reset through airflow. After the device is used, the fourth fixed shell 1508 and the third piston rod 1509 are used to monitor the patient's condition, so that the patient can no longer bear it and the patient's subconscious reaction is used to change the tightening state at the first time, thereby quickly relieving the patient's pain.

[0044] If the patient does not feel any discomfort during the entire detection process, the user controls the parts of the device to reset, the pressure in the adjustment shell 1514 is restored, and the spring between the adjustment shell 1514 and the fourth piston rod 1515 drives the fourth piston rod 1515 to move downward. During this process, the fourth piston rod 1515 drives the limit block 1517 to move backward through the rope, and at the same time squeezes the spring between the limit block 1517 and the sliding plate 1510 until the second fixed frame 1518 loses the limit on the limit block 1517. At this time, the tension spring between the sliding plate 1510 and the fourth fixed shell 1508 drives the sliding plate 1510, the third fixed plate 1516 and the limit block 1517 to move downward and reset synchronously, and the spring between the limit block 1517 and the sliding plate 1510 drives the limit block 1517 to reset. At this time, the use of the device is completed.
