[0023] Existing breast ultrasound robots typically consist of a gantry, a robotic arm suspended from the gantry, and an ultrasound probe located at the free end of the robotic arm. The robotic arm moves to move the ultrasound probe and scan the patient's breast. The inventors discovered that due to the complex contours of the breast surface and the individual variations in shape, existing robotic arms restrict the movement of the ultrasound probe when it is brought into contact with the breast for scanning. This makes it difficult to precisely control the applied pressure during the scanning process, resulting in a poor patient experience. Furthermore, there are areas on the breast surface where the probe cannot fully contact the breast, leading to incomplete and inaccurate imaging data and affecting the detection accuracy of the breast ultrasound robot.

[0024] To address the aforementioned technical problems, the inventors unexpectedly discovered that by incorporating a linear drive mechanism and a robotic arm assembly on the frame, the ultrasound probe is provided with six degrees of freedom of movement. This allows for better adjustment of the ultrasound probe's motion trajectory and its angle of contact with the breast, preventing the inability to scan the entire breast surface due to limited motion trajectory. It ensures that the ultrasound probe maintains the optimal angle for contact with the breast surface, resulting in comprehensive and accurate imaging data, thus improving the detection accuracy of the breast ultrasound robot. Simultaneously, when the ultrasound probe is in contact with the breast, the elastic element in the clamping assembly provides a buffering and energy-absorbing effect, offering a suitable contact pressure and improving patient comfort during the scan. Based on these findings, this invention provides a breast ultrasound robot. Figures 1 to 8 This is a specific embodiment of the breast ultrasound robot provided by this utility model.

[0025] Please see Figure 1 and Figure 2The system comprises a frame 1, a linear drive mechanism 2, a robotic arm assembly 3, a clamping assembly 6, and an ultrasonic probe 4. The frame 1 is equipped with a mounting base 11. The linear drive mechanism 2 includes a transverse drive mechanism 21, a longitudinal drive mechanism 22, and a vertical drive mechanism 23 connected in sequence. The transverse drive mechanism 21, mounted on the mounting base 11, drives the longitudinal drive mechanism 22 to move laterally. The longitudinal drive mechanism 22 drives the vertical drive mechanism 23 to move longitudinally. (See also...) Figure 7 The robotic arm assembly 3 includes a first rotary drive mechanism 31, a second rotary drive mechanism 32, and a third rotary drive mechanism 33 connected in sequence. The first rotary drive mechanism 31 is connected to a vertical drive mechanism 23, which drives the first rotary drive mechanism 31 to move vertically. The first axis of the first rotary drive mechanism 31 is parallel to the longitudinal direction and drives the second rotary drive mechanism 32 to rotate about the first axis. The second axis of the second rotary drive mechanism 32 is parallel to the transverse direction and drives the third rotary drive mechanism 33 to rotate about the second axis. (See also...) Figure 8 The clamping assembly 6 includes a connector 61, a fixing member 62, and an elastic member 63. The fixing member 62 has a fixing cavity (not shown in the figure), within which the ultrasonic probe 4 is housed. The fixing member 62 is slidably connected to the connector 61. One end of the elastic member 63 is connected to the connector 61, and the other end is connected to the fixing member 62. The connector 61 is connected to the free end of the third rotary drive mechanism 33. The third axis of the third rotary drive mechanism 33 is parallel to the vertical and is used to drive the connector 61 to rotate around the third axis.

[0026] The breast ultrasound robot 100 provided by this utility model can drive the ultrasound probe 4 mounted on the robotic arm assembly 3 to move horizontally, vertically, and longitudinally through the horizontal drive mechanism 21, the longitudinal drive mechanism 22, and the vertical drive mechanism 23 in the linear drive mechanism 2. The first rotary drive mechanism 31, the second rotary drive mechanism 32, and the third rotary drive mechanism 33 on the robotic arm assembly 3 can drive the ultrasound probe 4 to rotate around the first axis, the second axis, and the third axis, giving the ultrasound probe 4 six degrees of freedom. This allows for better adjustment of the ultrasound probe 4's motion trajectory and the angle at which the ultrasound probe 4 contacts the breast, ensuring that the ultrasound probe 4 can scan the entire breast and always maintains the optimal angle for contact scanning, resulting in comprehensive and accurate imaging data. Simultaneously, when the ultrasound probe 4 contacts the breast, the elastic element 63 in the clamping assembly 6 provides a certain buffering and energy absorption effect, offering a relatively suitable contact pressure. Therefore, the breast ultrasound robot 100 provided by this application not only improves the detection accuracy of breast scanning but also enhances patient comfort.

[0027] It is worth mentioning that the linear drive mechanism 2 is composed of an independent transverse drive mechanism 21, a longitudinal drive mechanism 22, and a vertical drive mechanism 23. This design allows the ultrasonic probe 4 to be driven by independent drive mechanisms in the transverse, longitudinal, and vertical movements, which is conducive to programming control to achieve precise positioning.

[0028] The following will describe, through exemplary illustration, a further detailed or improved implementation or process of the breast ultrasound robot 100, in order to further improve its efficiency, reliability, or for other improvements.

[0029] For easy installation and removal of the ultrasonic probe 4, please refer to [link / reference]. Figure 8 The fixing member 62 includes a first housing 621 and a second housing 622. The first housing 621 and the second housing 622 are hinged to each other on one side and connected to each other on the other side by a snap-fit ​​structure 623. The first housing 621 and the second housing 622 together form a fixing cavity (not shown in the figure), and the first housing 621 is slidably connected to the connecting member 61.

[0030] In some embodiments, the clamping assembly 6 further includes a pressure sensor 64, which is disposed on the connector 61 or the fixing member 62. When the pressure sensor 64 is disposed on the connector 61, one end of the elastic member 63 is connected to the pressure sensor 64, and the other end is connected to the fixing member 62; when the pressure sensor 64 is disposed on the fixing member 62, one end of the elastic member 63 is connected to the pressure sensor 64, and the other end is connected to the connector 61. Thus, the pressure sensor 64 can detect the force data of the elastic member 63, allowing the breast ultrasound robot 100 to adjust the position and angle of the ultrasound probe 4 in real time based on this force data. This maintains a constant pressure between the ultrasound probe 4 and the breast surface, improving the accuracy of the imaging data acquired by the ultrasound probe 4 and thereby enhancing the detection accuracy of the breast ultrasound robot 100.

[0031] To improve the scanning efficiency of the breast ultrasound robot 100, in some embodiments, the number of longitudinal drive mechanism 22, vertical drive mechanism 23, robotic arm assembly 3, clamping assembly 6, and ultrasound probe 4 are set to two, and they are arranged in a one-to-one correspondence. The two longitudinal drive mechanisms 22 are respectively connected to the transverse drive mechanism 21, and the transverse drive mechanism 21 is used to drive the two longitudinal drive mechanisms 22 to move laterally. In this way, the ultrasound probes 4 clamped on the two robotic arm assemblies 3 can be used to scan the patient's left and right breasts simultaneously.

[0032] For details, please refer to Figure 4The transverse drive mechanism 21 includes two first linear slides 211 arranged side-by-side on the mounting base 11 along the longitudinal direction. Each first linear slide 211 includes a main slide 2112, a secondary slide 2113, a first slide rail 2111, a first ball screw (not shown in the figure), and a first motor 2114.

The main slide 2112 is connected to a first nut (not shown in the figure) on the first ball screw. The first motor 2114 is connected to a first screw (not shown in the figure) of the first ball screw and is used to drive the first screw to rotate around its own axis to drive the main slide 2112 to move laterally. Please refer to [link to relevant documentation]. Figure 4 and Figure 5 Two longitudinal drive mechanisms 22 are provided. Each longitudinal drive mechanism 22 includes a second linear slide 221. The second linear slide 221 includes a mounting beam 2211, a second slide rail 2212, a longitudinal slider 2213, a second ball screw (not shown in the figure), and a second motor 2214. The two mounting beams 2211 are arranged side by side in the transverse direction. One end of the mounting beam 2211 is connected to the main slider 2112 of one of the first linear slides 211, and the other end is connected to the auxiliary slider 2113 of the other first linear slide 211. In this way, the two mounting beams 2211 can be driven to move in the transverse direction by the main sliders 2112 of the two first linear slides 211 respectively. The second slide rail 2212 is longitudinally mounted on the mounting beam 2211. The longitudinal slider 2213 is slidably mounted on the second slide rail 2212 and connected to the second nut (not shown in the figure) of the second ball screw. The second motor 2214 is connected to the second screw (not shown in the figure) of the second ball screw through the first synchronous belt mechanism 2215, and is used to drive the second screw to rotate around its own axis to drive the longitudinal slider 2213 connected to the second nut to move linearly in the longitudinal direction. Two vertical drive mechanisms 23 are provided. Each vertical drive mechanism 23 includes a connecting seat 232 and a third linear slide 231. The third linear slide 231 includes a third slide rail 2311, a vertical slider 2312, a third ball screw (not shown in the figure), and a third motor 2313. The connecting seat 232 is connected to the longitudinal slider 2213. The third slide rail 2311 is vertically mounted on the connecting seat 232. The vertical slider 2312 is slidably mounted on the third slide rail 2311 and connected to the third nut (not shown in the figure) of the third ball screw. The third motor 2313 is connected to the third screw (not shown in the figure) of the third ball screw through a second synchronous belt mechanism 2314. It is used to drive the third screw to rotate around its own axis to drive the vertical slider 2312 connected to the third nut to move vertically. The first rotary drive mechanism 31 is connected to the vertical slider 2312.

[0033] In some embodiments, the breast ultrasound robot 100 further includes a first cable chain mechanism 81, a second cable chain mechanism 82, and a third cable chain mechanism 83. A first mounting plate 16 is provided on the frame 1, and a second mounting plate 17 is provided on the side of the second slide rail 2212. The fixed end of the first cable chain mechanism 81 is connected to the first mounting plate 16, and the movable end is connected to the second mounting plate 17; the fixed end of the second cable chain mechanism 82 is connected to the second mounting plate 17, and the movable end is connected to the third slide rail 2311; the fixed end of the third cable chain mechanism 83 is connected to the connecting seat 232, and the movable end is connected to the first rotary drive mechanism 31. It should be noted that each of the above cable chain mechanisms is composed of multiple flexibly rotatable unit links, which are detachable. In reciprocating motion, the cable chain mechanism can provide traction and protection for internal cables, oil pipes, air pipes, water pipes, etc.

[0034] In some embodiments, see Figure 7 The first rotary drive mechanism 31 includes a first rotary motor 311, the second rotary drive mechanism 32 includes a second rotary motor 321, and the third rotary drive mechanism 33 includes a third rotary motor 331. The output end of the first rotary motor 311 is connected to the main body of the second rotary motor 321 and is used to drive the main body of the second rotary motor 321 to rotate around a first axis. The output end of the second rotary motor 321 is connected to the main body of the third rotary motor 331 and is used to drive the main body of the third rotary motor 331 to rotate around a second axis. The output end of the third rotary motor 331 is connected to the clamping assembly 6 and is used to drive the clamping assembly 6 to rotate around a third axis. This design allows the three rotary motors to independently control the rotation of the three axes, greatly expanding the movement flexibility and working space range of the distal ultrasonic probe 4, and also facilitating programmable control to achieve precise positioning.

[0035] In some embodiments, please refer to Figure 1 and Figure 2 The frame 1 is equipped with a support platform 12, which is located below the ultrasound probe 4. The breast ultrasound robot 100 also includes a scanning bed 5, which is movably mounted on the support platform 12. The scanning bed 5 is used for patients to lie flat for easy scanning. The support platform 12 provides a stable support platform for the scanning bed 5 and shares some of the load, improving the stability of the equipment. Moreover, since the scanning bed 5 is movably mounted on the support platform 12, medical staff can adjust the position of the patient's breast relative to the ultrasound probe 4 on the scanning bed 5 as needed, performing a coarse adjustment of the ultrasound probe 4 position before scanning. This provides a good foundation for subsequent fine adjustment of the ultrasound probe 4 position using the linear drive mechanism 2 and the robotic arm assembly 3. This method of coarse adjustment followed by fine adjustment can improve positioning efficiency.

[0036] In some embodiments, see Figure 1A guide mechanism 13 is provided between the support platform 12 and the scanning bed 5 to guide the movement of the scanning bed 5. For example, the guide mechanism 13 includes a movable guide rail 131 and a movable slider (not shown in the figure). The movable guide rail 131 is embedded in the upper surface of the support platform 12, and the movable slider is provided at the bottom of the scanning bed 5. The movable slider is slidably connected to the movable guide rail 131. In addition, in order to ensure that the scanning bed 5 can be stably fixed in the preset position after it moves to the preset position, the scanning bed 5 is also provided with a locking mechanism to restrict the sliding of the slider.

[0037] In some embodiments, please refer to Figure 2 and Figure 3 The breast ultrasound robot 100 also includes three image acquisition devices 7, which, exemplarily, are 3D cameras. By placing the three image acquisition devices 7 on the top and sides of the inner side of the frame 1, images of the patient's breast can be acquired from three different angles in a comprehensive manner, thereby obtaining three-dimensional image information of the breast. This allows the breast ultrasound robot 100 to determine the optimal scanning trajectory of the ultrasound probe 4 based on the three-dimensional image information, thus improving the accuracy of the imaging data acquired by the ultrasound probe 4 and consequently enhancing the detection accuracy of the breast ultrasound robot 100.

[0038] In some embodiments, the bottom of the frame 1 is also provided with a plurality of casters 14. The plurality of casters 14 facilitates the transport of the breast ultrasound robot 100, and preferably, each caster 14 is provided with a braking mechanism.

[0039] In some embodiments, the breast ultrasound robot 100 further includes a display screen 15 mounted on the frame 1. Thus, ultrasound images can be displayed in real time on the display screen 15 for medical personnel to refer to.

[0040] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model.
