And on the side surface of the docking plate, a storage plate is fixedly installed. Above the storage plate, a moving slide is arranged. And above the moving slide, a coating mechanism for automatically applying ultrasonic coupling agent to the ultrasonic probe is arranged.

[0009] Preferably, a transmission lead screw is rotatably installed inside the limit sliding groove. The transmission lead screw is threadedly connected through the foot support plate. And at the top end of the transmission lead screw, an adjustment motor located outside the positioning plate is installed. A decompression pad corresponding to the patient's thigh root is fixedly installed outside the rear end of the positioning plate. A positioning gyroscope is fixedly installed on the surface of the second support plate. The positioning gyroscope communicates with the controller through a Bluetooth signal. The controller controls the opening and closing of the adjustment motor. And on the upper surface of the controller, a display screen for displaying the real-time angle of the second support plate is arranged.

[0010] Preferably, the tightening mechanism includes a first airbag fixedly installed on the rear side surface of the second support plate and a second airbag fixedly installed inside the limit sliding groove. And the position of the first airbag corresponds to the position of the restraint belt.

[0011] Preferably, the restraint belt is in a ring structure and slides through the second support plate. The first airbag and the second airbag are interconnected through a connecting hose. And on the lower side surface of the foot support plate, a pressing plate for pressing the second airbag is fixedly installed.

[0015] Preferably, buffer springs are installed outside the front and rear ends of the guiding slide rod, and the smearing sponge is communicated with the storage tank through a delivery hose. The storage tank stores ultrasonic coupling agent inside and is fixedly installed on the upper surface of the docking plate.

[0016] Preferably, the delivery hose is connected to a delivery pump, and a stirring rod for stirring the ultrasonic coupling agent is rotatably installed inside the storage tank, and a transmission roller located outside the storage tank is coaxially and fixedly installed at the top end of the stirring rod.

[0017] Preferably, a heater is fixedly installed inside the storage tank, and the transmission roller is in contact friction with the upper surface of the guiding chute.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: This musculoskeletal ultrasound examination position fixing and assisting device adopts a novel structural design, and the specific content is as follows: 1. The doctor controls the adjusting motor through the controller to drive the transmission lead screw to rotate, and thus, due to the through-threaded connection between the transmission lead screw and the foot support plate, the foot support plate slides in the limit chute, and the first support plate and the second support plate are driven to rotate by the foot support plate, so that the first support plate and the second support plate support the patient's leg, facilitating the doctor to perform an ultrasound examination on the knee joint position of the patient. At the same time, the binding belt outside the second support plate is used to bind and fix the patient's calf position to prevent the patient's leg from moving randomly. Furthermore, when the angles of the first support plate and the second support plate are adjusted, the positioning gyroscope fixedly installed on the inner surface of the second support plate can real-time locate its angle data, transmit the data to the controller through Bluetooth signals and display it on the display screen, helping the doctor to understand the precise bending angle of the patient's knee in real time, so as to achieve a better examination effect. Furthermore, when the foot support plate slides in the limit chute, the extrusion plate fixedly installed on the lower side surface of the foot support plate squeezes the second airbag inside the limit chute. At this time, the air in the second airbag is transported to the first airbag through the connecting hose, causing the first airbag to expand. Under the expansion effect of the first airbag, the restraint belt is tightened, enabling the restraint belt to automatically restrain and fix the patient's leg without manual operation. Similarly, when the second support plate rotates to the lower side, the restraint belt can be automatically loosened. This process realizes automatic fixation and loosening, reducing manual operation.

[0019] 2. The pulling effect of the connecting spring on the fixing plate causes the fixing plate to slide relative to the connecting rod. Finally, the fixing plate is used to clamp the left and right ends of the examination hospital bed, achieving the purpose of fixing the entire device.

[0020] 3. The storage plate is installed and connected to the entire device through the docking plate. The position of the storage plate can be changed by the sliding of the docking plate in the guiding chute, facilitating the operation of the doctor. At the same time, a moving slide is arranged above the storage plate, and the ultrasonic probe for examination can be placed on the ultrasonic probe bracket on the moving slide, facilitating taking. The moving slide can slide on the guiding slide rod, enabling it to switch between the left and right sides of the device, facilitating the doctor to operate at different positions; Further, after the ultrasonic probe is placed on the ultrasonic probe bracket, its bottom contacts the coating sponge. The ultrasonic coupling agent in the storage box is transported to the coating sponge through the transport hose under the action of the transport pump, so that the coating sponge can be used to coat the ultrasonic probe. At the same time, the heater in the storage box can heat the ultrasonic coupling agent to avoid causing greater irritation to the patient when used at a lower temperature.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1: Please refer to Figures 1 - 3, in order to achieve the purpose of facilitating the examination by supporting the patient's leg in this embodiment, the following technical solutions are provided, and specifically disclosed: a mounting plate 1 installed on the examination bed, two positioning plates 2 are fixedly installed on the upper surface of the mounting plate 1, a first support plate 3 is rotatably installed on the upper surface of the positioning plate 2, a second support plate 4 is rotatably installed at the top of the first support plate 3, and a foot support plate 5 is rotatably installed at the bottom end of the second support plate 4. A sliding adjustment structure is formed between the foot support plate 5 and the limit sliding groove 7 opened on the upper surface of the positioning plate 2. A transmission screw rod 8 is rotatably installed inside the limit sliding groove 7, and the transmission screw rod 8 is threadedly connected through the foot support plate 5. And a regulating motor 9 located outside the positioning plate 2 is fixedly installed at the top end of the transmission screw rod 8. A positioning gyroscope 34 is fixedly installed on the surface of the second support plate 4, and the positioning gyroscope 34 communicates with the controller 32 through a Bluetooth signal. The controller 32 controls the opening and closing of the regulating motor 9, and a display screen 33 for displaying the real-time angle of the second support plate 4 is arranged on the upper surface of the controller 32. A decompression pad 6 corresponding to the patient's thigh root is fixedly installed outside the rear end of the positioning plate 2. Inverted "L"-shaped fixing plates 15 are installed on both the left and right sides of the mounting plate 1. The fixing plates 15 clamp the left and right ends of the examination bed, and a rubber friction pad 1501 is fixedly installed inside the lower end of the fixing plates 15. The fixing plates 15 are slidably connected through the connecting rod 16, and the connecting rod 16 is fixedly installed outside the side surface of the positioning plate 2. And a connecting spring 17 that provides a pulling force to the fixing plates 15 is arranged outside the connecting rod 16.

[0025] When using the device, first place the mounting plate 1 on the examination bed. At this time, under the elastic pulling action of the connecting spring 17, the fixing plate 15 is pulled towards the middle position, so as to cooperate with the friction pad 1501 on its inner side to achieve the purpose of clamping and fixing. Then the patient lies on the examination bed with the legs corresponding to the positioning plate 2 (at this time, the decompression pad 6 is used to reduce the pressure on the patient's thigh root to avoid discomfort), and the feet are placed on the foot support plate 5. Then the doctor controls the rotation of the regulating motor 9 through the controller 32 as needed. Rotate 9, drive the transmission screw rod 8 to rotate by using the regulating motor 9, so that the transmission screw rod 8 drives the foot support plate 5 threadedly installed outside it to slide relative to the limit sliding groove 7, so that the foot support plate 5 drives the first support plate 3 and the second support plate 4 to rotate, arching the patient's leg (the first support plate 3 supports the patient's thigh, and the second support plate 4 supports the patient's calf), which is convenient for the doctor to perform knee joint ultrasound examination. The positioning gyroscope 34 on the inner surface of the second support plate 4 determines its angle in real time, and transmits the angle to the controller 32 through a Bluetooth signal and displays it on the display screen 33. The doctor can accurately understand the adjusted angle through the display screen 33 to achieve the purpose of accurate control.

[0026] Embodiment Two: Please refer to Figures 4 - 6, in order to achieve the purpose of automatic binding and loosening in this embodiment, the following technical solutions are provided, and specifically disclosed: A binding strap 10 for fixing the patient's calf is installed outside the second support plate 4, and a tensioning mechanism for automatically tightening the binding strap 10 is arranged behind the second support plate 4. The tensioning mechanism includes a first airbag 11 fixedly installed on the rear surface of the second support plate 4 and a second airbag 12 fixedly installed inside the limit sliding groove 7. The position of the first airbag 11 corresponds to the position of the binding strap 10. The binding strap 10 is in a ring structure and slides through the second support plate 4. The first airbag 11 and the second airbag 12 are interconnected through a connecting hose 13. And a pressing plate 14 for pressing the second airbag 12 is fixedly installed on the lower side surface of the foot support plate 5.

[0027] When the foot support plate 5 slides in the limit sliding groove 7 and drives the second support plate 4 to rotate upward, the pressing plate 14 fixedly installed on the lower side surface of the foot support plate 5 presses the second airbag 12. When the second airbag 12 is pressed, the air inside it is transported to the first airbag 11 through the connecting hose 13. At this time, the first airbag 11 expands. When the first airbag 11 expands, it pulls the binding strap 10 to move backward, making the binding strap 10 tighten and fix the patient's calf, avoiding involuntary movement of the patient's legs during the examination. In this process, there is no need for the doctor to manually operate the binding strap 10, and the whole is automatically bound.

[0028] Embodiment Three: Please refer to Figures 7 - 10 , in order to achieve the purpose of automatically applying ultrasonic coupling agent in this embodiment, the following technical solutions are provided, and specifically disclosed: A docking plate 18 is arranged at the middle position of the upper surface of the mounting plate 1. The docking plate 18 and the guiding sliding groove 27 arranged on the side surface of the positioning plate 2 form a sliding structure. And a placing plate 19 is fixedly installed on the side surface of the docking plate 18. Above the placing plate 19, there is a moving sliding table 21. And above the moving sliding table 21, there is an applying mechanism for automatically applying ultrasonic coupling agent to the ultrasonic probe. The applying mechanism includes a applying sponge 24 fixedly installed on the upper surface of the moving sliding table 21 and an ultrasonic probe bracket 22. The moving sliding table 21 and the guiding sliding rod 20 fixedly installed on the upper surface of the placing plate 19 form a penetrating sliding structure. Buffer springs 23 are installed outside the front and rear ends of the guiding sliding rod 20. And the applying sponge 24 is interconnected with the storage tank 26 through a delivery hose 25. The storage tank 26 stores ultrasonic coupling agent and is fixedly installed on the upper surface of the docking plate 18. The delivery hose 25 is connected to a delivery pump 28. And a stirring rod 30 for stirring the ultrasonic coupling agent is rotatably installed inside the storage tank 26. And a transmission roller 29 located outside the storage tank 26 is coaxially fixedly installed at the top end of the stirring rod 30. A heater 31 is fixedly installed inside the storage tank 26. And the transmission roller 29 is in contact friction with the upper surface of the guiding sliding groove 27.

[0029] When examining a patient, first move the moving slide 21 to the side close to the doctor's operation (the moving slide 21 slides outside the guiding slide bar 20. When it moves to the outermost position, the buffer spring 23 buffers the moving slide 21 to avoid damage caused by impact during long-term use). When the doctor needs to perform other tasks during the examination, place the ultrasonic probe used for examination on the ultrasonic probe bracket 22. At this time, the bottom of the ultrasonic probe contacts the sponge 24 for smearing. The delivery pump 28 is turned on in advance. Under the action of the delivery pump 28, the ultrasonic coupling agent in the storage tank 26 is delivered to the sponge 24 for smearing through the delivery hose 25, so that the ultrasonic coupling agent is smeared on the surface of the ultrasonic probe by the sponge 24 for smearing. The placement plate 19 is connected to the whole device through the docking plate 18, and the docking plate 18 can slide in the guiding chute 27 on the side of the positioning plate 2 to adjust the position of the placement plate 19. When the docking plate 18 slides in the guiding chute 27, the driving roller 29 outside the storage tank 26 moves relative to the upper surface of the guiding chute 27, so that the driving roller 29 drives the ultrasonic coupling agent stirring rod 30 inside the storage tank 26 to rotate under the action of friction (the heater 31 inside the storage tank 26 can heat the ultrasonic coupling agent, so as to reduce the stimulation to the patient when used at a lower temperature. The stirring rod 30 is used to stir the ultrasonic coupling agent to make it heat more evenly during heating).
