A horizontally rotatable second support arm 14 is mounted on the first hinge seat 19. A second hinge seat 33 is provided at the free end of the second support arm 14. A vertically rotatable third support arm 15 is mounted on the second hinge seat 33. The free end of the third support arm 15 is connected to an adjusting rod 32. An ultrasonic probe 16 is connected; an arm support 20 is installed on the second support arm 14, and a second rotating rod 34 is fixed at one end of the third support arm 15 away from the ultrasonic probe 16. The second rotating rod 34 is rotatably installed in the second hinge seat 33; a third power assembly 28 is provided on one side of the second hinge seat 33, and one end of the second rotating rod 34 extends out of the second hinge seat 33 and is connected to the third power assembly 28 for transmission; adjusting the third power assembly 28 drives the third support arm 15 to rotate up and down, and the third support arm 15 drives the ultrasonic probe 16 to move up and down.

[0024] In this invention, the operator places their arm on the arm support 20 and holds the adjustment rod 32 to perform an ultrasound examination on the target area of ​​the patient. The first power component 26 can adjust the circumferential angle of the upright rod 12, thereby adjusting the horizontal position of the first support arm 13, the second support arm 14, the third support arm 15 and the ultrasound probe 16, and making a large-scale adjustment in the horizontal position.

[0025] The second power assembly 27 can adjust the rotation of the second support arm 14 along the first rotating rod 35 in the circumferential direction, thereby adjusting the horizontal position of the second support arm 14, the third support arm 15 and the ultrasonic probe 16, and realizing a small-amplitude adjustment in the horizontal position.

[0026] The first power assembly 26 and the second power assembly 27 work together to achieve adjustment at multiple positions, providing a large coverage area for the target to be inspected.

[0027] The third power assembly 28 can adjust the vertical position of the third support arm 15. In particular, when the operator needs to apply downward pressure to the target area of ​​the patient, by adjusting the third power assembly 28, the third support arm 15 can be rotated downward, driving the ultrasound probe 16 to press downward, thus obtaining a more realistic ultrasound image. This avoids the operator having to apply downward pressure with their wrist for a long time, reducing the probability of joint inflammation and protecting the operator's health while further ensuring the effectiveness of the patient examination.

[0028] Furthermore, the third power assembly 28 includes a third motor, a third worm, a third worm wheel, and a third worm support. The third motor is fixedly mounted on one side of the second hinge seat 33, and the third worm is installed at the output end of the third motor. The third worm is installed in the third worm support, and the third worm support is fixedly mounted on the second hinge seat 33. One end of the second rotating rod 34 extends out of the second hinge seat 33 and is fixedly mounted with the third worm wheel. The third worm wheel contacts and drives the third support arm 15 to rotate up and down.

[0029] Figure 1 and Figure 2 As shown, the third worm gear support of the third power assembly 28 is fixedly installed on the second hinge seat 33, and the third worm gear is installed in the third worm gear support through a bearing; the third worm gear support provides support and fixation for the third worm gear, the third worm gear is rotatable, and one end of the third worm gear extends out of the third worm gear support and is connected to the third motor for transmission; when the third motor starts, the third worm gear contacts the third worm wheel for transmission, driving the second rotating rod 34 and the third support arm 15 to rotate together, thereby realizing the up and down movement of the ultrasonic probe 16.

[0030] Furthermore, a second power assembly 27 is provided at the bottom of the first hinge seat 19. The second power assembly 27 includes a second motor, a second worm, a second worm wheel, and a second worm support. A first rotating rod 35 is fixedly installed at one end of the second support arm 14 away from the ultrasonic probe 16. The first rotating rod 35 is rotatably installed in the first hinge seat 19. A second motor is fixedly installed at the bottom of the first hinge seat 19. A second worm is installed at the output end of the second motor. The second worm is installed in a second worm support, which is fixedly installed at the bottom of the first hinge seat 19. A second worm wheel is installed at one end of the first rotating rod 35 after it extends out of the first hinge seat 19. The second worm wheel contacts the second worm, driving the second support arm 14 to rotate horizontally.

[0031] The second power assembly 27 operates on a similar principle to the third power assembly 28.

[0032] The second power assembly 27 can adjust the rotation of the second support arm 14 along the first rotating rod 35 in the circumferential direction, thereby adjusting the horizontal position of the second support arm 14, the third support arm 15 and the ultrasonic probe 16, and realizing a small-amplitude adjustment in the horizontal position.

[0033] Furthermore, the upright 12 is rotatably mounted on the base 11 via bearings, and a first power assembly 26 is installed between the bottom of the upright 12 and the base 11. The first power assembly 26 includes a first motor 22, a first worm 23, a first worm wheel 24, and a first worm support 25. The first motor 22 is fixedly mounted on the top of the base 11, and the first worm 23 is installed at the output end of the first motor 22. The first worm 23 is installed in the first worm support 25, and the first worm support 25 is fixedly mounted on the base 11. The first worm wheel 24 is fixedly installed at the bottom of the upright 12. The first worm wheel 24 contacts and drives the first worm 23 to rotate horizontally.

[0034] The first worm gear support 25 of the first power assembly 26 is fixedly installed on the base 11. The first worm gear 23 is rotatably installed in the first worm gear support 25 through a bearing. The first worm gear support 25 supports and fixes the first worm gear 23. The first worm gear 23 is rotatable. One end of the first worm gear 23 extends out of the first worm gear support 25 and is connected to the first motor 22 for transmission. When the first motor 22 starts, it drives the first worm gear 23 to contact and transmit power with the first worm wheel 24, thereby driving the upright 12 to rotate.

[0035] The upright 12 is rotated to adjust the horizontal position of the first support arm 13, the second support arm 14, the third support arm 15, and the ultrasonic probe 16, allowing for significant adjustments to the horizontal position.

[0036] The first power assembly 26 and the second power assembly 27 work together to enable multiple adjustments to the position of the ultrasonic probe 16, providing a large coverage area for the target to be examined.

[0037] It should be noted that the worm gear structure features a self-locking function, ensuring that the moving parts of the bracket will not shift position when the operator stops, thus providing strong stability. The slow transmission speed of the worm gear structure facilitates precise position adjustment of the ultrasonic probe 16.

[0038] Furthermore, the adjusting rod 32 includes a fixed rod 29, a universal joint 30, and a fixed base 31. One end of the fixed rod 29 is connected to the ultrasonic probe 16 by a screw connection. The end of the third support arm 15 near the ultrasonic probe 16 is connected to the fixed base 31 by a screw connection. The universal joint 30 is installed between the fixed rod 29 and the fixed base 31. The fixed rod 29 is provided with a control key 36.

[0039] One end of the fixing rod 29 is connected to the ultrasonic probe 16 by a screw connection.

The end of the third support arm 15 is provided with an internal thread, and the fixing seat 31 is provided with an external thread. The external thread on the fixing seat 31 is screwed to the internal thread of the third support arm 15 for detachable installation.

[0041] The fixed rod 29 and the fixed base 31 are connected by a universal joint 30. The universal joint 30 has a damping setting, which facilitates the adjustment of the ultrasonic probe 16 at multiple angles on the third support arm 15.

[0042] The fixed rod 29 is equipped with a control key 36, which can remotely control the first motor 22, the second motor and the third motor in the bracket, thereby adjusting the position.

[0043] Furthermore, the upright 12 is provided with several threaded holes 17 spaced apart, and the first support arm 13 is provided with through holes that match the threaded holes 17; the upright 12 and the through holes of the first support arm 13 are fixedly connected by knob bolts 18.

[0044] When adjusting the up and down position of the upright 13, align the threaded hole 17 with the through hole on the first support arm 13, and connect and fix it with the knob bolt 18 to complete the adjustment of the up and down position.

[0045] Furthermore, a locking strap 21 is fixed to the top of the third support arm 15, and Velcro is provided on the locking strap 21.

[0046] The locking strap 21 can fix the wrist to the third support arm 15; when in use, the third support arm 15 rotates downward to pull the wrist to move downward together, reducing excessive force on the wrist and reducing the risk of arthritis.

[0047] Alternatively, the mounting base 31 can be separated from the third support arm 15, and the position or angle of the ultrasonic probe 16 can be manually adjusted by holding the fixing rod 29.

[0048] Adjusting the control key 36 changes the position of the ultrasound probe 16. It can also adjust the third support arm 15 to rotate downwards, causing the ultrasound probe 16 to press down and contact the target area of ​​the patient, making the detection more accurate, saving time and effort, protecting the operator's arm, and preventing joint inflammation.

[0049] Furthermore, the armrest 20 has several ventilation holes (not shown in the figure), and the armrest 20 is made of silicone.

[0050] The armrest 20 features ventilation holes and is made of silicone material to enhance operator comfort.

[0051] The first motor 22, the second motor, and the third motor are all stepper motors, which have high positioning accuracy, self-locking capability, large torque, and good stability.

[0052] A hollow space is set inside the base 11, and a power supply (not shown in the figure) is set inside the hollow space. The power supply is electrically connected to the first motor 22, the second motor, the third motor, the remote control device, and the control key 36. All of the above components are commercially available and belong to the prior art, so they will not be described in detail here.
