[0033] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connections (couplings).

[0034] This embodiment provides an ultrasonic imaging device.

[0035] Please refer to Figures 1-3, the ultrasonic imaging device includes a volumetric ultrasonic probe 1000, an ultrasonic main unit (not shown), and a display device (not shown).

[0036] The volumetric ultrasonic probe 1000 is used to emit ultrasonic waves to a target tissue and receive corresponding echo signals. The ultrasonic main unit is connected to the volumetric ultrasonic probe 1000, and the ultrasonic main unit is used to process the echo signals to generate ultrasonic images. The display device is connected to the ultrasonic main unit, and the display device is used to display the ultrasonic images.

[0037] When using the ultrasonic imaging device for examination, ultrasonic waves are emitted to the target tissue of the person to be examined through the volumetric ultrasonic probe 1000, and corresponding echo signals are received through the volumetric ultrasonic probe 1000. Then, the echo signals are processed by the ultrasonic main unit to generate ultrasonic images, and finally the ultrasonic images are displayed on the display device.

[0038] On the other hand, the present embodiment also provides a volumetric ultrasonic probe 1000, which can be applied to the above ultrasonic imaging device.

[0039] Please refer to Figures 1-3 , the volumetric ultrasonic probe 1000 includes a probe housing 100, a sound head base 200, a sound head assembly 300, a sound head rotating shaft 400, and a driving assembly 500.

[0040] The sound head base 200 is disposed inside the probe housing 100 and is integrally formed with or fixedly connected to the probe housing 100. The sound head assembly 300 is used to emit ultrasonic waves to the target tissue and receive the echo signals of the ultrasonic waves. The sound head rotating shaft 400 rotatably connects the sound head assembly 300 to the sound head base 200. The driving assembly 500 includes a driving motor 510, a first pulley 520, a second pulley 530, and a transmission belt 540. The output shaft of the driving motor 510 is connected to the first pulley 520, the second pulley 530 is connected to the sound head rotating shaft 400, and the transmission belt 540 drives and connects the first pulley 520 and the second pulley 530. The driving motor 510 can drive the first pulley 520 to rotate, so as to drive the sound head rotating shaft 400 and the sound head assembly 300 to rotate on the sound head base 200.

[0041] When it is necessary to adjust the detection range of the sound head assembly 300, the driving motor 510 is used to drive the first pulley 520 to rotate. The first pulley 520 drives the second pulley 530 to rotate through the transmission belt 540. Then, the second pulley 530 drives the sound head rotating shaft 400 to rotate, and finally, the sound head assembly 300 is driven to rotate through the sound head rotating shaft 400, thereby changing the detection range of the sound head assembly 300. On the one hand, the use of the transmission belt 540 has higher transmission accuracy than the wire rope transmission, and the material of the transmission belt 540 generally has stronger anti-rust and anti-corrosion capabilities than the wire rope. On the other hand, since the transmission belt 540 is indirectly connected to the sound head assembly 300 through the sound head rotating shaft 400, compared with the way of directly connecting the transmission belt 540 to the sound head assembly 300, there is no need to set a complex structure for fixing the transmission belt 540 on the sound head assembly 300, and the occupied surface mounting space of the sound head assembly 300 is also reduced.

[0042] Please refer to Figure 1 and 2 , in an embodiment, a rotating shaft seat 210 is provided on one side of the sound head base 200 facing the sound head assembly 300, and the sound head rotating shaft 400 is rotatably connected to the rotating shaft seat 210. Both the sound head assembly 300 and the second pulley 530 are fixedly connected to the sound head rotating shaft 400, and the center line of the second pulley 530 coincides with the center line of the sound head rotating shaft 400.

[0043] The rotatable bearing of the sound head rotating shaft 400 is realized through the rotating shaft seat 210. On the one hand, since both the sound head assembly 300 and the second pulley 530 are fixedly connected to the sound head rotating shaft 400, when the driving assembly 500 works, the transmission belt 540 can drive the sound head rotating shaft 400 to rotate on the rotating shaft seat 210 through the second pulley 530, and then drive the sound head assembly 300 to rotate through the sound head rotating shaft 400. On the other hand, since the center line of the second pulley 530 coincides with the center line of the sound head rotating shaft 400, that is, the second pulley 530 and the sound head rotating shaft 400 are coaxially arranged, the transmission stability between the second pulley 530 and the sound head rotating shaft 400 is relatively good.

[0044] Please refer to Figure 1 and 2 , in an embodiment, an installation groove 310 is provided on one side of the sound head assembly 300 facing the rotating shaft seat 210. The opposite ends of the sound head rotating shaft 400 are respectively fixedly connected to the two opposite inner walls of the installation groove 310 correspondingly, and at least part of the second pulley 530, the transmission belt 540, and the rotating shaft seat 210 are located in the installation groove 310.

[0045] By providing an installation groove 310 on the side of the sound head assembly 300 facing the rotating shaft seat 210, on the one hand, it is beneficial to increase the installation space of the sound head assembly 300, facilitating the connection of the sound head rotating shaft 400 to the sound head assembly 300 and the connection of the second pulley 530 to the sound head rotating shaft 400. On the other hand, by arranging at least part of the second pulley 530, the transmission belt 540, and the rotating shaft seat 210 within the installation groove 310, the space utilization rate within the installation groove 310 is improved, and the exposure of the transmission structure on the outer surface of the sound head assembly 300 is reduced.

[0046] Please refer to Figure 1 and 2 , in an embodiment, the rotating shaft seat 210 includes a first connection portion 211 and a second connection portion 212. The first connection portion 211 is connected to the sound head base 200. One end of the second connection portion 212 is connected to the first connection portion 211, and the other end extends towards the sound head assembly 300. The second connection portion 212 has a rotating shaft hole (not shown), and the sound head rotating shaft 400 is rotatably inserted into the rotating shaft hole.

[0047] Through the cooperation of the first connection portion 211 and the sound head base 200, the installation of the rotating shaft seat 210 on the sound head base 200 is achieved. Through the rotatable cooperation of the sound head rotating shaft 400 and the rotating shaft hole, the rotatable connection between the sound head rotating shaft 400 and the rotating shaft seat 210 is achieved. Specifically, the first connection portion 211 can be connected to the sound head base 200 by screw connection, glue bonding, welding, or other suitable connection methods. The sound head rotating shaft 400 is fixedly connected or integrally formed with the sound head assembly 300. Under the action of the belt 540, the sound head rotating shaft 400 rotates around the sound head base, thereby driving the sound head assembly 300 to rotate relative to the sound head base 200 along the rotation axis of the sound head rotating shaft 400, that is, the axis of the rotating shaft 400.

[0048] Please refer to Figure 1 and 2 , in an embodiment, two rotating shaft seats 210 are configured. The two rotating shaft seats 210 are respectively rotatably connected to the opposite ends of the sound head rotating shaft 400, and there is an installation gap 220 between the two rotating shaft seats 210. At least part of the second pulley 530 and the transmission belt 540 are located within the installation gap 220.

[0049] On the one hand, the two rotating shaft seats 210 carry the acoustic head rotating shaft 400 from the opposite ends of the acoustic head rotating shaft 400, so that the installation and rotation stability of the acoustic head rotating shaft 400 on the acoustic head base 200 is better. On the other hand, at least part of the second pulley 530 and the transmission belt 540 are arranged in the installation gap 220, which not only improves the space utilization rate of the installation gap 220, makes the structure of the volumetric ultrasound probe 1000 more compact, but also makes the second pulley 530 and the transmission belt 540 roughly located in the middle of the acoustic head rotating shaft 400, thus facilitating to improve the transmission stability.

[0050] Please refer to Figure 1 and 2 , in one embodiment, the probe housing 100 includes an acoustic head housing 110 and a connection housing 120. The acoustic head housing 110 is connected to one end of the connection housing 120. The internal space of the acoustic head housing 110 and the internal space of the connection housing 120 together form a first cavity 130. The first pulley 520, the second pulley 530 and the transmission belt 540 are all located in the first cavity 130.

[0051] By connecting the internal space of the acoustic head housing 110 with the internal space of the connection housing 120, the internal space of the acoustic head housing 110 and the internal space of the connection housing 120 together form a first cavity 130. The first cavity 130 can be filled with a coupling liquid to transmit ultrasonic waves. And since the first pulley 520, the second pulley 530 and the transmission belt 540 are all located in the first cavity 130, it is convenient to seal the first cavity 130, and thus it is beneficial to reduce the risk of leakage of the coupling liquid in the first cavity 130.

[0052] Please refer to Figure 1 and 2 , in one embodiment, the volumetric ultrasound probe 1000 further includes a handle base 600. The probe housing 100 further includes a handle housing 140. The handle housing 140 is connected to the end of the connection housing 120 away from the acoustic head housing 110. The handle base 600 is connected between the connection housing 120 and the handle housing 140. The internal space of the handle housing 140 forms a second cavity 150. The handle base 600 seals and isolates the first cavity 130 and the second cavity 150. The drive motor 510 is connected to the side of the handle base 600 facing the second cavity 150.

[0053] When using the volumetric ultrasound probe 1000, the probe housing 100 can be used for the user to hold. By providing a handle base 600 between the connection housing 120 and the handle housing 140, the first cavity 130 and the second cavity 150 can be hermetically isolated through the handle base 600, and an installation position for mounting the drive motor 510 is provided through the handle base 600. Moreover, since the drive motor 510 is connected to the side of the handle base 600 facing the second cavity 150, that is, the drive motor 510 is located within the second cavity 150, the drive motor 510 is isolated from the coupling liquid within the first cavity 130, thereby preventing the coupling liquid from entering the drive motor 510 and causing damage to the drive motor 510.

[0054] Please refer to Figure 1 and 2 , in one embodiment, the volumetric ultrasound probe 1000 is an endocavity ultrasound probe, and the acoustic head housing 110 and the connection housing 120 form an insertion housing 160 of the endocavity ultrasound probe. The insertion housing 160 is used to be inserted into the human body when the endocavity ultrasound probe performs ultrasonic imaging, and the handle housing 140 is used for the user to hold when the insertion housing 160 is inserted into the human body.

[0055] In an actual application scenario when performing an endocavity examination on a subject to be detected, the user can hold the handle housing 140 and extend the insertion housing 160 formed by the acoustic head housing 110 and the connection housing 120 into the human body, so as to facilitate the examination of the target tissue in the human body through the acoustic head assembly 300 within the insertion housing 160, and facilitate the user to perform various operations on the volumetric ultrasound probe 1000 through the handle housing 140 located outside the human body.

[0056] Please refer to Figure 1 and 3 , in one embodiment, the drive assembly 500 further includes a commutation assembly 550. The commutation assembly 550 includes a first bevel gear 551, a second bevel gear 552, a commutation shaft 553, and a commutation seat 554. The commutation seat 554 is connected to the handle base 600, and the commutation shaft 553 is rotatably connected to the commutation seat 554. The first bevel gear 551 is connected to the output shaft of the drive motor 510, the second bevel gear 552 is connected to one end of the commutation shaft 553, and the first pulley 520 is connected to the other end of the commutation shaft 553. The first bevel gear 551 meshes with the second bevel gear 552, and the rotation axis of the first bevel gear 551 is perpendicular to the rotation axis of the second bevel gear 552.

[0057] When the driving assembly 500 is working, the first bevel gear 551 is driven to rotate by the driving motor 510, and then the second bevel gear 552 is driven to rotate by the first bevel gear 551, and then the reversing shaft 553 is driven to rotate by the second bevel gear 552, and then the first pulley 520 is driven to rotate by the reversing shaft 553. Since the rotation axis of the first bevel gear 551 is perpendicular to the rotation axis of the second bevel gear 552, that is, the conversion of the rotation direction can be achieved through the cooperation of the first bevel gear 551 and the second bevel gear 552, so that the installation position and orientation of the driving motor 510 can be configured more flexibly without being limited by the rotation direction. In the volumetric ultrasound probe 1000, the driving motor 510 is arranged along the longitudinal direction of the volumetric ultrasound probe 1000. Because the intracavitary probe is a probe inserted into the human body, in order to avoid causing discomfort to the human body, the radial direction of the probe is generally not too large. In this case, the arrangement of the driving motor 510 inside the intracavitary probe can only be longitudinal, which can also be understood as being arranged along the axial direction of the probe, and can be specifically regarded as being arranged along Figure 1 In this case, a belt drive must be used to perform a reversal. Otherwise, if the output shaft of the drive motor 510 is directly connected to the drive belt 540, it will take up a larger volume on the one hand, and it will be inconvenient to transmit force on the other hand.

[0058] Please refer to Figure 1 and 2 In one embodiment, the drive assembly 500 also includes a driving shaft 560 and a coupling 570, the coupling 570 coaxially connects the driving shaft 560 with the output shaft of the drive motor 510, and the driving shaft 560 extends sealedly from the side of the handle base 600 toward the second cavity 150 to the side of the handle base 600 toward the first cavity 130, and the first bevel gear 551 is connected to one end of the driving shaft 560 located in the first cavity 130.

[0059] On the one hand, the output shaft of the driving motor 510 is connected to the driving shaft 560 through the coupling 570, so that the driving motor 510 can drive the driving shaft 560 to rotate, and the transmission between the driving motor 510 and the driving shaft 560 is relatively stable. On the other hand, because the driving shaft 560 passes through the handle base 600 in a sealed manner, the power output by the driving motor 510 can be transmitted from the second cavity 150 to the first cavity 130 without causing leakage of the coupling fluid in the first cavity 130.

[0060] Please refer to Figure 1 and 2 In one embodiment, the volumetric ultrasound probe 1000 further includes a belt adjusting member 700, which is pressed against the transmission belt 540. The belt adjusting member 700 can move in the direction of the pressing force between the belt adjusting member 700 and the transmission belt 540 to change the tightness of the transmission belt 540.

[0061] The user can adjust the drive belt 540 to an appropriate tightness degree through the belt adjusting member 700, which is beneficial to ensuring the transmission stability of the drive belt 540 and improving the service life of the drive belt 540. Specifically, the belt adjusting member 700 can be a belt adjusting block, and the belt adjusting block can move in a direction perpendicular to the extending direction of the drive belt 540 to change the magnitude of the pressing force between the belt adjusting block and the drive belt 540, thereby changing the tightness degree of the drive belt 540.

[0062] The above uses specific examples to elaborate on the present utility model, which is only used to help understand the present utility model and is not intended to limit the present utility model. For those skilled in the technical field to which the present utility model pertains, several simple deductions, deformations or substitutions can also be made according to the idea of the present utility model.
