[0002] Musculoskeletal ultrasound is a type of ultrasound, which refers to a diagnostic method of ultrasound applied to the musculoskeletal system. The main parts of the examination are the muscles and skeletal system, while the so-called ordinary ultrasound is to examine the abdomen, heart, blood vessels and other parts. Musculoskeletal ultrasound uses a high-frequency probe to scan the bone cortex and surrounding soft tissue lesions, and can comprehensively evaluate the synovial hyperplasia, pannus formation, joint effusion, cartilage and bone erosion, and inflammatory changes of the soft tissue around the joints of the diseased joints, and can be compared with the contralateral or other joints. In addition, the ultrasonic high-frequency probe can also clearly display the structure and running relationship of various parts such as muscles, tendons and ligaments, determine the extent of the lesions, and provide a new and effective imaging examination method for clinical use. At present, when performing musculoskeletal ultrasound examination on patients, the patient needs to keep the body position still for a period of time, and change the body position according to the needs.

DETAILED DESCRIPTION

[0030] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0031] like Figure 1-12As shown, the present invention provides a body position fixation auxiliary device for musculoskeletal ultrasonic examination, including a bed board 1, wherein two leg support devices are provided on the front side of the upper end of the bed board 1, and the leg support devices respectively include a rotatable thigh support plate 3, and the front end of the thigh support plate 3 is respectively provided with a support pad 8 that can move up and down, and the lower end of the support pad 8 is respectively provided with a calf support plate 9 that can swing up and down, and the leg support device also includes a locking mechanism that can be opened and closed, and when the locking mechanism is opened, it can limit and fix the thigh support plate 3, the support pad 8 and the calf support plate 9.

[0032] like Figure 1-5 As shown, the bed board 1 is an examination bed, and a plurality of supporting legs 2 are fixedly connected to the lower end surface of the bed board 1, and the supporting legs 2 are used to support and fix the bed board 1; the patient lies on the bed board 1 with his legs placed on the corresponding leg supporting device, and when the doctor performs an ultrasonic examination on the patient's lower limbs, a specific body position support can be provided for the patient to reduce the patient's physical exertion; the patient places the thigh on the thigh supporting board 3, the knee fossa on the supporting pad 8, and the calf on the calf supporting board 9. When the patient's lower limb position needs to be adjusted, the rotatable thigh supporting board 3 can assist the patient's legs to swing outward, that is, to swing left and right, and the supporting pad 8 that can move up and down can assist in driving the patient's knee to move up or down, and adjust the patient's lower limb to a bent or straight state. By setting the thigh supporting board 3 that can swing up and down, the position of the patient's calf can be specifically adjusted according to the needs of the ultrasonic examination, and the locking mechanism can be set to lock the positions of the thigh supporting board 3, the supporting pad 8 and the calf supporting board 9, that is, the patient can be stably supported during use, thereby maintaining a specific body position.

[0033] The lower end surface of the calf support plate 9 is fixedly connected to extension rods 12 on both sides, and the outer surfaces of the two extension rods 12 are respectively covered with limit seats 13 that can move forward and backward. The upper end surfaces of the two extension seats are fixedly connected to a footrest seat 14, and the footrest seats 14 are respectively provided with straps 24.

[0034] like Figure 5 As shown, the extension rod 12 is used to support the limited footrest 14. Even if the limited seat 13 and the footrest 14 can only move forward and backward at the front end of the two extension rods 12, the footrest 14 can support the patient's feet. The patient's feet can be fixed by the provided straps 24, so that the patient's calves are fixed on the calf support plate 9. The straps 24 are prior art and will not be described in detail. By providing a limited seat 13 that can move forward and backward, the position of the footrest 14 can be adjusted and adaptively adjusted according to the length of the patient's legs.

[0035] The middle part of the lower end surface of the footrest seat 14 is slidably connected with a pull plate 18, and the left and right sides of the lower end surface of the footrest seat 14 are slidably connected with a clamping seat 16, the outer ends of the two clamping seats 16 are respectively provided with an arc clamping plate 22, and the outer surface of the extension rod 12 is respectively provided with an arc clamping groove 23 matching the arc clamping plate 22, the inner ends of the two clamping seats 16 are respectively provided with a first sliding pin 17, and the pull plate 18 is respectively provided with a first inclined groove 19 matching the first sliding pin 17.

[0036] like Figure 6 As shown, the pull plate 18 can be slidably connected to the lower end surface of the pedal seat 14 forward and backward, so that the pull plate 18 can only move forward and backward, and the clamping seat 16 can be slidably connected to the lower end surface of the pedal seat 14 left and right, so that the clamping seat 16 and the arc clamping plate 22 can only move left and right at the lower end of the pedal seat 14; when the arc clamping plate 22 is at the outermost end and can engage with the arc clamping groove 23, the forward and backward movement of the pedal seat 14 can be restricted, that is, the position of the pedal seat 14 is fixed; when the arc clamping plate 22 is at the innermost end, it can be disengaged from the arc clamping groove 23, at this time The footrest seat 14 can slide back and forth on the outer surface of the extension rod 12, that is, adjust the position of the footrest seat 14; through the engagement of the first sliding pin 17 and the first inclined groove 19, when the pull plate 18 moves forward, the first sliding pin 17, the clamping seat 16, and the arc-shaped clamping plate 22 can be driven to move inward, that is, when the pull plate 18 moves backward, the first sliding pin 17, the arc-shaped clamping plate 22, etc. can be driven to move outward and reset, that is, when the pull plate 18 moves forward and backward, the arc-shaped clamping plate 22 can be controlled to engage or disengage with the arc-shaped clamping groove 23.

[0037] The lower end surfaces of the foot pedals are respectively fixedly connected with support pads 21 , the front end surfaces of the support pads 21 are respectively fixedly connected with first tension springs 20 , and the front ends of the first tension springs 20 are respectively fixedly connected to the corresponding pull plates 18 .

[0038] like Figure 6 As shown, the support pad 21 can support and fix the first tension spring 20, and the first tension spring 20 can have a backward pulling force on the pull plate 18, even if the pull plate 18 has a backward driving force under normal circumstances, that is, it can make the two arc-shaped clamping plates 22 at the outermost ends under normal circumstances, so that the arc-shaped clamping plates 22 and the arc-shaped clamping grooves 23 are stably engaged, even if the footrest 14 is in a stable state under normal circumstances, no further details are given; when it is necessary to adjust the position of the footrest 14, the pull plate 18 is driven to move forward so that the arc-shaped clamping plate 22 and the arc-shaped clamping groove 23 are disengaged, and the position of the footrest 14 can be adjusted at this time. When the pull plate 18 is released, the pull plate 18 can be moved backward and reset under the tension of the first tension spring 20, and the footrest 14 is limited and fixed again.

[0039] The lower end surfaces of the thigh support plates 3 are fixedly connected with L-shaped support plates 7, and the locking mechanisms include control boxes 30 slidably connected to the L-shaped support plates 7, and the upper end surfaces of the control boxes 30 are fixedly connected with vertical plates 31, and the vertical plates 31 are slidably connected with square columns 25, and the support pads 8 are fixedly connected to the upper end surfaces of the corresponding square columns 25, and the lower sides of the left and right end surfaces of the square columns 25 are fixedly connected with long pins 27, and the left and right sides of the lower end surface of the thigh support plates 3 are fixedly connected with side plates 28, and the side plates 28 are respectively provided with long oblique grooves 29 that match the long pins 27.

[0040] like Figure 6-7 As shown, the L-shaped support plate 7 is used to support and limit the locking mechanism, i.e., the control box 30 and other components. The control box 30 can slide forward and backward on the inner wall of the L-shaped support plate 7. The vertical plate 31 is used to support and limit the square column 25. The square column 25 can be slidably connected to the left and right end surfaces of the vertical plate 31; Figure 4 As shown, the inner wall of the front end of the thigh support plate 3 is also slidably connected to the limit plate 26, the square column 25 passes through the limit plate 26, and can be slidably connected to the inner wall of the limit plate 26 up and down, and the limit plate 26 can be slidably connected to the inner wall of the thigh support plate 3 front and back. Through the limit support of the limit plate 26, the square column 25 and the support pad 8 can be smoothly moved up and down or left and right; the installation and shape of the side plate 28 and the long pin 27 are as shown in FIG. Figure 7 As shown, when the control box 30 moves backward, it can drive the vertical plate 31, the square column 25, the support pad 8, the long pin 27, etc. to move backward synchronously. When the long pin 27 moves backward, it will engage with the long inclined groove 29, which will drive the long pin 27 to move backward and upward at the same time. That is, the corresponding square column 25 and the support seat move backward and upward at the same time. When the support pad 8 moves backward and upward at the same time, it can drive the patient's knee pit to move backward and upward at the same time, thereby assisting the patient's legs to bend or straighten their knees.

[0041] The control box 30 is provided with a rotatable handle 37 at the lower end, and a disc 38 is coaxially fixed to the upper end of the handle 37. The left and right inner walls of the control box 30 are slidably connected with second pins 42, and the inner ends of the two second pins 42 are fixed with second sliding pins 41. The disc 38 is provided with a second oblique key groove 40 matched with the second sliding pin 41, and the inner walls of the left and right ends of the lower side of the L-shaped support plate 7 are respectively provided with a plurality of second slots 49 matched with the second pins 42.

[0042] like Figure 7 , 12As shown, a rotating shaft is fixedly connected to the inner wall at the center of the disc 38 and the handle 37, and the rotating shaft is rotatably connected to the inner wall of the control box 30. The rotating shaft can limit the disc 38 and the handle 37 to rotate synchronously; the second bayonet 42 can be slidably connected to the inner wall of the control box 30 to the left and right. When the second bayonet 42 is at the outermost side, it can engage with the second slot 49, thereby limiting the left and right movement of the control box 30, that is, limiting the movement of the support pad 8. When the disc 38 rotates, the second sliding pin 41 is engaged with the second oblique key slot 40. When the handle 37 is driven, the disc 38 can be driven to rotate and the second pin 42 can move inwards or outwards, that is, the second pin 42 can be driven to move inwards or outwards. When the second pin 42 moves inwards, it can disengage from the second slot 49, and the control box 30 can move forwards and backwards. Therefore, when the handle 37 is driven, the disc 38 can be driven to rotate and the second pin 42 can move inwards. When the second pin 42 moves inwards, the second slot 49 will be disengaged, and the control box 30 can move forwards and backwards.

[0043] The upper end of the handle 37 is coaxially fixed with a crank 45 , one end of the crank 45 is rotatably connected with a second tension spring 46 , and the other end of the second tension spring 46 is fixed to the corresponding inner wall of the control box 30 .

[0044] like Fig.12 As shown, the crank 45 is fixedly connected to the outer surface of the rotating shaft. When the handle 37 and the crank 45 are rotated, the second tension spring 46 can be driven to extend. After the handle 37 is released, the crank 45, the handle 37 and other components can be driven to reset under the tension of the second tension spring 46, that is, the second bayonet 42 can be driven outward again, so that the second bayonet 42 can be stably engaged with the second slot 49, which will not be repeated.

[0045] The left and right sides of the upper end surface of the bed board 1 are respectively fixed with support shafts 4, and the thigh support plates 3 are respectively rotatably connected to the outer surfaces of the support shafts 4. The outer surfaces of the support shafts 4 are also respectively fixed with spur gears 5, and the lower end surfaces of the thigh support plates 3 are respectively provided with clamping strips 6 that match the spur gears 5.

[0046] like Figure 4 As shown, the support shaft 4 can limit the thigh support plate 3 to only swing left and right, and the clamping strip 6 can be slidably connected to the lower end surface of the thigh support plate 3 forward and backward; when the clamping strip 6 is engaged with the spur gear 5, the thigh support plate 3 can be limited to rotate, and when the clamping strip 6 moves forward and disengages from the spur gear 5, the thigh support plate 3 can be swung and adjusted.

[0047] The left and right sides of the inner wall at the lower end of the L-shaped support plate 7 are slidably connected with horizontal plates 43, and horizontal grooves 44 matching with the second sliding pins 41 are respectively opened on the horizontal plates 43. Extension pins 47 are fixedly connected to the rear sides of the upper end surfaces of the horizontal plates 43, and V-shaped grooves 48 matching with the extension pins 47 are respectively opened on the clamping strips 6.

[0048] like Figure 7-8 As shown, the horizontal plate 43 can be slidably connected to the inner wall of the L-shaped support plate 7, and the horizontal plate 43 passes through the control box 30, that is, the control box 30 can move forward and backward on the outer surface of the horizontal plate 43. Through the cooperation of the set horizontal groove 44 and the second sliding pin 41, when the second sliding pin 41 moves inward or outward, it can drive the horizontal plate 43 to move inward or outward, and when the second sliding pin 41 follows the control box 30 to move forward and backward, it can move forward and backward on the inner wall of the horizontal groove 44, and the two do not affect each other; when the horizontal plate 43 moves inward, Or when it moves outward, it will drive the extension pin 47 to move inward or outward. When the extension pin 47 moves inward, it will engage with the V-shaped groove 48, which will drive the clamping strip 6 to move forward. When the clamping strip 6 moves forward, it will disengage from the spur gear 5. At this time, the thigh support plate 3 can be adjusted to swing to the specified position; and when the handle 37 is released, the clamping strip 6 can be moved backward and reset under the pulling force of the second tension spring 46, that is, the clamping strip 6 is engaged with the spur gear 5 again, so that the thigh support plate 3 can be fixed.

[0049] The inner walls of the upper ends of the control box 30 are slidably connected with square sliders 36, the inner walls of the square sliders 36 are fixedly connected with vertical pins 35, and the discs 38 are respectively provided with first oblique key slots 39 that match the vertical pins 35; the inner walls of the square columns 25 are respectively slidably connected with vertical plates 32, and the vertical plates 32 are respectively sleeved on the outer surfaces of the corresponding vertical pins 35; the front end surfaces of the square columns 25 are respectively slidably connected with fixed seats 11, the front end surfaces of the fixed seats 11 are respectively hinged with first connecting rods 10, the upper ends of the first connecting rods 10 are respectively hinged on the corresponding calf support plates 9, the rear end surfaces of the fixed seats 11 are respectively fixedly connected with first bayonet pins 34, and the front end surfaces of the vertical plates 32 are respectively provided with a plurality of first bayonet slots 33 that match the first bayonet pins 34.

[0050] like Figure 5 , 9 As shown in -12, the fixed seat 11 can be slidably connected to the front end surface of the square column 25 up and down, and when the square column 25 moves forward and backward, it can drive the fixed seat 11 to move forward and backward; the rear end of the calf support plate 9 is hinged to the lower end surface of the support pad 8, and can limit the calf support plate 9 to swing up and down on the lower side of the front end of the support pad 8; when the fixed seat 11 moves up and down, it can drive the lower end of the first connecting rod 10 to move upward or downward, and the upper end of the first connecting rod 10 will drive the corresponding calf support plate 9 to swing downward or upward; Fig.10As shown, the first latch pin 34 can be limited by the engagement of the first latch pin 34 with the first latch slot 33, that is, when the first latch pin 34 is engaged with the first latch slot 33, the corresponding position of the fixed seat 11 is in a fixed state and will not move upward or downward, that is, the corresponding calf support plate 9 is in a fixed state and will not flip and swing up and down, on the contrary, when the first latch pin 34 is disengaged from the first latch slot 33, the corresponding calf support plate 9 can swing to adjust the position; the vertical plate 32 can be slidably connected to the inner wall of the square column 25 front and back, and the vertical plate 32 can be slidably connected to the outer surface of the vertical pin 35 up and down, that is, when the square column 25, the vertical plate 32, the fixed seat 11, and the calf support plate 9 move up and down, the corresponding parts can keep synchronously following the square column 25 and the support pad 8 to move up and down, and when the vertical pin 35 moves back and forth, the vertical plate 32 can be driven to move back and forth, that is, the vertical plate 32 can follow the square column 25 to move up and down, and can follow the vertical pin 35 to move back and forth, and the two do not affect each other; Fig.11 As shown, the square slider 36 can be slidably connected to the inner wall of the control box 30 forward and backward, and the square slider 36 can limit the vertical pin 35 to move forward and backward; through the engagement of the vertical pin 35 with the first oblique key groove 39, when the disc 38 rotates, the vertical pin 35 can be driven to move backward, and when the vertical pin 35 moves backward, it will drive the vertical plate 32 and the first slot 33 to move backward. When the first slot 33 moves backward to disengage from the first slot 34, the height of the fixed seat 11 can be adjusted, that is, the swing angle of the calf support plate 9 can be adjusted; when the handle 37 is rotated, the disc 38 can be driven to rotate, and when the disc 38 rotates, it will drive the second slot 34. 42 moves inwardly and disengages from the second slot 49, the vertical plate 32 and the first slot 33 move backward and disengage from the first latch pin 34, and the clamping strip 6 moves forward and disengages from the spur gear 5. At this time, the locking mechanism is in a closed state, and the height and front and rear position of the support pad 8, the up and down swing angle of the calf support plate 9, and the left and right rotation angle of the thigh support plate 3 can be synchronously adjusted to quickly adjust the inspection position and improve efficiency. When the handle 37 is released, it can be reset under the tension of the second tension spring 46, that is, the locking mechanism is opened, and the position of the thigh support plate 3, the position of the support pad 8, and the position of the calf support plate 9 are fixed.

[0051] When the present invention is in use, the patient lies on the bed board 1 with both legs placed on the corresponding leg support device. When the doctor performs an ultrasonic examination on the patient's lower limbs, a specific body position support can be provided for the patient to reduce the patient's physical exertion; the patient places the thigh on the thigh support board 3, the knee fossa on the support pad 8, and the calf on the calf support board 9. When the patient's lower limb position needs to be adjusted, the rotatable thigh support board 3 can assist the patient's legs to swing outward, that is, to swing left and right. The support pad 8 that can move up and down can assist in driving the patient's knee to move upward or downward, and adjust the patient's lower limbs to a bent or straight state. By setting the thigh support board 3 that can swing up and down, the position of the patient's calf can be specifically adjusted according to the needs of the ultrasonic examination.
