Description

Technical Field

[0001] This invention relates to the technical field of medical devices, and more specifically to an auxiliary system for ultrasound examination. Background Technology

[0002] Currently, when ultrasound physicians perform ultrasound examinations, if they hold the ultrasound probe to examine the patient's area, their arms are in a suspended, unsupported state. After working for a long time, this can easily cause muscle fatigue in the ultrasound physician's arms, which may reduce the efficiency of the ultrasound examination and even affect the image quality.

[0003] Therefore, a hand support device that can be controlled by an ultrasound probe is needed to provide support for the ultrasound physician's arm during the examination. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the above-mentioned background technology and provide an auxiliary system for ultrasound examination, which can reduce the fatigue of ultrasound physicians and solve the technical problems of existing hand support devices, such as the need for ultrasound physicians to move them manually, low flexibility, and inconvenience in operation.

[0005] To achieve the above objectives, the present invention provides an auxiliary system for ultrasound examination, comprising a movable robotic arm, wherein the movable robotic arm comprises a first arm segment, a second arm segment, a third arm segment, a fourth arm segment, a fifth arm segment, and a sixth arm segment that are rotatably connected in sequence; the first arm segment has a plurality of mounting holes at its head end, and a transfer plate is hinged to the end of the sixth arm segment, wherein a hand rest is mounted on the transfer plate.

[0006] Furthermore, the ultrasound examination auxiliary system also includes an ultrasound probe, which includes a probe body and a start button and a reset button.

[0007] Furthermore, a gyroscope is installed inside the probe body.

[0008] Furthermore, the first arm segment has a large-diameter end and a small-diameter end, and the diameter of the first arm segment gradually decreases from the large-diameter end to the small-diameter end to form a trumpet-shaped structure. The mounting holes are arranged at intervals along the circumference of the large-diameter end of the first arm segment.

[0009] Furthermore, the second arm segment is an L-shaped structure formed by connecting the first and second branches, the first branch of the second arm segment is rotatably connected to the small-diameter end of the first arm segment, and the second branch of the second arm segment is rotatably connected to the third arm segment.

[0010] Furthermore, the third arm segment is a U-shaped structure formed by connecting the third, fourth, and fifth branches in sequence. The third branch of the third arm segment is rotatably connected to the second arm segment, and the fifth branch of the third arm segment is rotatably connected to the fourth arm segment.

[0011] Furthermore, the fourth arm segment is a U-shaped structure formed by connecting the sixth, seventh, and eighth branches in sequence. The sixth branch of the fourth arm segment is rotatably connected to the third arm segment, and the eighth branch of the fourth arm segment is rotatably connected to the fifth arm segment.

[0012] Furthermore, the fifth arm segment is an L-shaped structure formed by connecting the ninth and tenth branches, with the ninth branch of the fifth arm segment rotatably connected to the fourth arm segment, and the tenth branch of the fifth arm segment rotatably connected to the sixth arm segment.

[0013] Furthermore, the sixth arm segment has a cylindrical structure, and the middle part of the sixth arm segment is rotatably connected to the fifth arm segment.

[0014] Furthermore, the hand rest is in the shape of an arc plate, and a flexible pad is provided on the hand rest, with ventilation holes opened on the flexible pad.

[0015] Furthermore, the hand rest is positioned above the adapter plate and is connected to it via damping rotation.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] Firstly, the movable robotic arm of the ultrasound examination auxiliary system of this invention can be installed in various ways, such as flat mounting, upside down mounting, or side mounting. By holding the ultrasound probe with a gyroscope, the movable robotic arm can be controlled to quickly and accurately move the hand support to the examination site. During the movement, the hand support supports the arm, which greatly reduces the arm muscle fatigue of the ultrasound physician, improves the efficiency of ultrasound examination, and at the same time maintains the stability of operation and ensures the quality of ultrasound images.

[0018] Secondly, the auxiliary system for ultrasound examination of the present invention is used in conjunction with an ultrasound probe equipped with a gyroscope. The robotic arm has six degrees of freedom, the adapter plate is installed at the end of the robotic arm, the tray is installed on the adapter plate, the tray can rotate on the adapter plate, and there is damping in the rotation process.

[0019] Thirdly, when using the auxiliary system for ultrasound examination of the present invention, the ultrasound physician adjusts the bottom of the ultrasound probe to point to the examination site of the patient, and then presses the start button of the ultrasound probe. The robotic arm will move the hand support to the examination site, and then the start button is released to examine the patient. This allows the ultrasound physician to have a hand support to support the arm when examining any part of the body, which makes it easier for the ultrasound physician to examine the examination site and greatly reduces the fatigue of the ultrasound physician.

[0024] The following examples illustrate the implementation of the present invention in detail, but they do not constitute a limitation on the invention and are merely illustrative. Furthermore, the advantages of the present invention will become clearer and easier to understand by explaining them.

[0025] like Figure 1 The illustrated auxiliary system for ultrasound examination includes a movable robotic arm 1. The movable robotic arm 1 comprises a first arm segment 1.1, a second arm segment 1.2, a third arm segment 1.3, a fourth arm segment 1.4, a fifth arm segment 1.5, and a sixth arm segment 1.6, which are rotatably connected in sequence. The first arm segment 1.1 has several mounting holes 1.11 at its tip. A transition plate 2 is hinged to the end of the sixth arm segment 1.6, and a hand rest 3 is mounted on the transition plate 2. The movable robotic arm 1 has six arm segments and six degrees of freedom. Depending on the actual usage requirements and available space, it can be mounted horizontally, upside down, or sideways via the mounting holes in the first arm segment 1.1. The hand rest 3 is an arc-shaped plate with a flexible pad 5. The flexible pad 5 has ventilation holes and can be made of silicone to improve comfort and increase breathability. The hand rest 3 is positioned above the transition plate 2 and is rotatably connected to it. During the examination, the arm can rotate the hand rest on the transition plate, and damping occurs during this rotation. The support for the tray can be replaced with a wide rope handle, which can also reduce the fatigue of ultrasound physicians.

[0026] like Figure 2As shown, the auxiliary system for ultrasound examination also includes an ultrasound probe 4, which comprises a probe body 4.1. The probe body 4.1 has a start button 4.2 and a reset button 4.3. A gyroscope is installed inside the probe body 4.1 to detect changes in the angle of the ultrasound probe, thereby determining the direction of movement of the robotic arm.

[0027] like Figure 3 As shown, the first arm segment 1.1 has a large-diameter end and a small-diameter end. The diameter of the first arm segment 1.1 gradually decreases from the large-diameter end to the small-diameter end, forming a trumpet-shaped structure. Mounting holes 1.11 are arranged at intervals along the circumference of the large-diameter end of the first arm segment 1.1. The second arm segment 1.2 is an L-shaped structure formed by connecting the first branch segment 1.21 and the second branch segment 1.22. The first branch segment 1.21 of the second arm segment 1.2 is rotatably connected to the small-diameter end of the first arm segment 1.1, and the second branch segment 1.22 of the second arm segment 1.2 is rotatably connected to the third arm segment 1.3. The third arm segment 1.3 is a U-shaped structure formed by connecting the third branch segment 1.31, the fourth branch segment 1.32, and the fifth branch segment 1.33 of the third arm segment 1.3 is rotatably connected to the second arm segment 1.2, and the fifth branch segment 1.33 of the third arm segment 1.3 is rotatably connected to the fourth arm segment 1.4. The fourth arm segment 1.4 is a U-shaped structure formed by the sequential connection of the sixth branch segment 1.41, the seventh branch segment 1.42, and the eighth branch segment 1.43. The sixth branch segment 1.41 of the fourth arm segment 1.4 is rotatably connected to the third arm segment 1.3, and the eighth branch segment 1.43 of the fourth arm segment 1.4 is rotatably connected to the fifth arm segment 1.5. The fifth arm segment 1.5 is an L-shaped structure formed by the connection of the ninth branch segment 1.51 and the tenth branch segment 1.52 of the fifth arm segment 1.5. The ninth branch segment 1.51 of the fifth arm segment 1.5 is rotatably connected to the fourth arm segment 1.4, and the tenth branch segment 1.52 of the fifth arm segment 1.5 is rotatably connected to the sixth arm segment 1.6. The sixth arm segment 1.6 has a cylindrical structure, and its middle part is rotatably connected to the fifth arm segment 1.5.

[0028] The working principle of the ultrasound examination auxiliary system of this invention:

[0029] The movable robotic arm is installed upside down. It is fixed to the ceiling or the support on the top of the hospital bed through the mounting hole 1.11. At this time, the hand support device is folded up when the reset button 4.3 of the ultrasound probe 4 is pressed. When folded up, the hand support device occupies less space. The movable robotic arm consists of a first arm segment 1.1, a second arm segment 1.2, a third arm segment 1.3, a fourth arm segment 1.4, a fifth arm segment 1.5, and a sixth arm segment 1.6. The movable robotic arm allows for more flexible movement of the hand support. During use, when the ultrasound physician's arm 6 is placed on the hand support 3, and the bottom of the ultrasound probe body 4.1 is aligned with the area to be examined, pressing the start button 4.2 will move the movable robotic arm towards the area to be examined. Once the hand support reaches the area, releasing the start button 4.2 will stop its movement. The ultrasound physician can then examine the area. During the examination, the physician can swing their arm 6 to rotate the hand support 3 relative to the adapter plate 2 to facilitate the examination. After the examination, pressing the reset button 4.3 will automatically return the hand support to its initial state.

[0030] The ultrasound probe 4 is equipped with a gyroscope. The x, y, and z axes of the gyroscope's xyz coordinate system are in the same direction as those of the movable robotic arm. When the ultrasound physician's arm 6 changes the bottom orientation of the ultrasound probe 4's probe body 4.1, the gyroscope measures the angle change of the ultrasound probe 4 and transmits this angle parameter to the movable robotic arm. When the start button 4.2 is pressed, the movable robotic arm will move the hand support according to the angle parameter. When the start button 4.2 is released, the hand support device stops moving.

[0031] The above are merely specific embodiments of the present invention. It should be noted that any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the protection scope of the present invention. Any other aspects not described in detail are prior art.
