As a type of ultrasonic probe, a volume ultrasonic probe generally includes a sound head assembly and a housing. The sound head assembly is arranged in a sealed space formed by the housing, and the sealed space is filled with a coupling liquid. The function of the coupling liquid is to fill the gap between the sound head and the housing to conduct ultrasonic waves.

[0036] An embodiment provides an ultrasonic imaging device.

[0037] Please refer to Figures 1-4 , the ultrasonic imaging device includes a volumetric ultrasonic probe 1000, an ultrasonic host (not shown), and a display device (not shown).

[0038] Please refer to Figure 1 , the volumetric ultrasonic probe 1000 is used to emit ultrasonic waves to a target tissue and receive corresponding echo signals. The ultrasonic host is connected to the volumetric ultrasonic probe 1000, and the ultrasonic host is used to process the echo signals to generate ultrasonic images. The display device is connected to the ultrasonic host, and the display device is used to display the ultrasonic images.

[0039] 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 the corresponding echo signals are received through the volumetric ultrasonic probe 1000. Then, the echo signals are processed by the ultrasonic host to generate ultrasonic images, and finally the ultrasonic images are displayed on the display device.

[0040] On the other hand, this embodiment further provides a volumetric ultrasound probe 1000, which can be applied to the above-mentioned ultrasound imaging device.

[0041] Please refer to Figures 1-4 , the volumetric ultrasound probe 1000 includes a probe housing 100, a sound head assembly 200 and a compensator 300.

[0042] Please refer to Figures 1-4 , the probe housing 100 has a sealed first cavity 110, the sound head assembly 200 is installed in the first cavity 110, and the sound head assembly 200 is used to emit ultrasonic waves to a target tissue and receive echo signals of the ultrasonic waves. The compensator 300 is arranged in the first cavity 110, the compensator 300 has a compensation cavity 310, and the compensation cavity 310 is hermetically separated from the first cavity 110. The compensation cavity 310 has a vent 320, and the vent 320 communicates with the external space of the compensation cavity 310, so that the gas in the compensation cavity 310 can flow between the compensation cavity 310 and the external space. At least part of the compensator 300 is a flexible part, and the flexible part can deform under the action of the pressure change of the coupling liquid in the first cavity 110 to change the volume of the compensation cavity 310. The compensator 300 has a mating side 330, and the inner wall of the probe housing 100 has a mating portion 120. The shape of the mating side 330 is adapted to the shape of the mating portion 120, and the mating side 330 fits with the mating portion 120, that is, when the compensator 300 is arranged in the probe housing 100, the installation between the mating side 330 and the mating portion 120 is adapted and matched.

[0043] When the compensator 300 is installed in the first cavity 110, the mating side 330 of the compensator 300 fits with the mating portion 120 on the inner wall of the probe housing 100. Since the shapes of the mating side 330 and the mating portion 120 are similar, the degree of fit between the mating side 330 and the mating portion 120 is higher, which is beneficial to reducing the dead space between the mating side 330 and the mating portion 120. This not only improves the space utilization rate in the first cavity 110, but also is beneficial to increasing the volume of the compensator 300. After the volume of the compensator 300 increases, the compensation ability of the compensator 300 will be improved, and the coupling liquid to be filled in the first cavity 110 will be reduced, which is beneficial to reducing the weight of the volumetric ultrasound probe 1000.

[0044] Please refer to Figure 1 、 2With reference to FIGS. 3 and 4, it should be noted that in actual application scenarios, when the coupling liquid in the enclosed space expands and contracts with temperature changes, the pressure of the coupling liquid in the first cavity 110 will change. At this time, at least part of the compensating member 300 will deform under the action of the pressure change to change the volume of the compensation cavity 310, so as to compensate for the change in the pressure of the coupling liquid in the first cavity 110. It can be seen that the compensation ability of the compensating member 300 is directly related to the volume of the compensation cavity 310. Therefore, the solution in this embodiment improves the utilization rate of the dead space, thereby increasing the volume of the compensating member 300, which is conducive to improving the compensation ability of the compensating member 300. Moreover, after the volume of the compensating member 300 increases, the amount of coupling liquid to be filled in the first cavity 110 will be reduced, which is also conducive to reducing the weight of the volumetric ultrasound probe 1000.

[0045] Please refer to Figure 1 、 2 and 4, in one embodiment, the mating side 330 is in shape-fitting contact with the mating portion 120.

[0046] Since the shapes of the mating side 330 and the mating portion 120 are similar, when the mating side 330 contacts the mating portion 120, the two can achieve a fit, avoiding the formation of dead space due to shape mismatch, which is conducive to maximizing the use of the space between the mating side 330 and the mating portion 120 to increase the volume of the compensating member 300, and thus is conducive to further improving the compensation ability of the compensating member 300 and reducing the weight of the volumetric ultrasound probe 1000.

[0047] Please refer to Figure 1 、 2 and 4, in one embodiment, the mating portion 120 includes an adjacent first mating portion 121 and a second mating portion 122. The second mating portion 122 is closer to the acoustic head assembly 200 than the first mating portion 121. The probe housing 100 has a central axis. The perpendicular distance between the first mating portion 121 and the central axis gradually decreases in the direction approaching the second mating portion 122. The mating side 330 includes adjacent first and second regions 331 and 332. The second region 332 is closer to the acoustic head assembly 200 than the first region 331. The perpendicular distance between the first region 331 and the central axis gradually decreases in the direction approaching the second region 332. The first region 331 fits with the first mating portion 121, and the second region 332 fits with the second mating portion 122.

[0048] On the one hand, both the first mating part 121 and the first region 331 gradually contract towards the central axis in the direction close to the acoustic head assembly 200, so that the shapes of the first mating part 121 and the first region 331 are adapted to each other. On the other hand, when the volumetric ultrasound probe 1000 is applied to the examination of the human body cavity, the part of the connection housing 140 close to the acoustic head assembly 200 needs to extend into the human body. Therefore, both the first mating part 121 and the first region 331 gradually contract towards the central axis in the direction close to the acoustic head assembly 200, so that the radial dimension of the part of the connection housing 140 close to the acoustic head assembly 200 is smaller, thus facilitating entry into the human body cavity. Specifically, please refer to Figure 2 , the central axis can be regarded as Figure 2 the axis L1 in

[0049] Please refer to Figure 1 、 2 and 4. In one embodiment, both the first mating part 121 and the second mating part 122 are configured as arc-shaped structures, and the radian of the first mating part 121 is greater than that of the second mating part 122. Both the first region 331 and the second region 332 are configured as arc-shaped structures, and the radian of the first region 331 is greater than that of the second region 332.

[0050] Since the radian of the first mating part 121 is greater than that of the second mating part 122, and the radian of the first region 331 is greater than that of the second region 332, the shapes of the first mating part 121 and the first region 331 are adapted to each other, and the shapes of the second mating part 122 and the second region 332 are similar.

[0051] Please refer to Figure 1 and 2 . In one embodiment, the probe housing 100 includes an acoustic head housing 130 and a connection housing 140. The connection housing 140 has a first end, and the acoustic head housing 130 is connected to the first end. The acoustic head assembly 200 is located in the internal space of the acoustic head housing 130, the compensating member 300 is located in the internal space of the connection housing 140, and the mating part 120 is located on the inner wall of the connection housing 140. The internal space of the acoustic head housing 130 is connected to the internal space of the connection housing 140 and together form a first cavity 110.

[0052] On the one hand, the compensating member 300 is arranged in the connection housing 140 with a larger space, so as to facilitate leaving more space for installing the acoustic head assembly 200 in the acoustic head housing 130, thus reasonably distributing the space in the first cavity 110. On the other hand, since the internal space of the acoustic head housing 130 is connected to the internal space of the connection housing 140, when the coupling liquid fills the first cavity 110, the compensating member 300 can compensate for the change in the coupling liquid pressure in the entire first cavity 110.

[0053] Please refer to Figures 1-3, in one embodiment, the probe housing 100 further includes a handle housing 150. The connecting housing 140 has a second end disposed opposite to the first end, and the handle housing 150 is connected to the second end. The internal space of the handle housing 150 is hermetically separated from the internal space of the connecting housing 140.

[0054] On the one hand, when using the volumetric ultrasound probe 1000, the handle housing 150 can be used for a user to hold. On the other hand, since the internal space of the handle housing 150 is hermetically separated from the internal space of the connecting housing 140, the coupling liquid in the first cavity 110 will not leak into the handle housing 150, so that some waterproof components can be arranged in the handle housing 150, for example, the drive motor 610.

[0055] Please refer to Figure 1 , in one embodiment, the transducer head housing 130 and the connecting housing 140 are used to extend into the human body cavity during ultrasonic examination, and the handle housing 150 is used to provide a holding part outside the human body cavity.

[0056] In an actual application scenario when performing an intracavitary examination on a subject to be detected, the user can hold the handle housing 150 and extend the transducer head housing 130 and the connecting housing 140 into the human body, so as to facilitate the examination of the target tissue in the human body through the transducer head assembly 200 in the transducer head housing 130, and it is also convenient for the user to perform various operations on the volumetric ultrasound probe 1000 through the handle housing 150 located outside the human body.

[0057] Please refer to Figure 1 、 2 and 4, in one embodiment, the volumetric ultrasound probe 1000 further includes a handle base 400. The handle base 400 is disposed between the internal space of the connecting housing 140 and the internal space of the handle housing 150, and hermetically separates the internal space of the connecting housing 140 from the internal space of the handle housing 150. The handle housing 150 and the handle base 400 enclose a second cavity 160. The compensating member 300 is connected to the handle base 400, and the vent port 320 of the compensating member 300 communicates with the second cavity 160.

[0058] By providing the handle base 400 between the connecting housing 140 and the handle housing 150, the first cavity 110 and the second cavity 160 can be hermetically isolated by the handle base 400, and an installation position for mounting the compensating member 300 is provided by the handle base 400. Specifically, the compensating member 300 can be connected to the side of the handle base 400 facing the first cavity 110, and the compensation cavity 310 of the compensating member 300 communicates with the second cavity 160 through the vent port 320.

[0059] Please refer to Figures 1-4, in one embodiment, the volumetric ultrasound probe 1000 further includes a transducer head base 500, the transducer head base 500 is connected to the inner wall of the transducer head housing 130 and / or the connection housing 140, the transducer head assembly 200 is rotatably connected to the transducer head base 500, a driving assembly 600 is further provided on the handle base 400, the driving assembly 600 is used to drive the transducer head assembly 200 to rotate, the compensating member 300 further has an avoidance side 340, and there is a gap between the avoidance side 340 and the driving assembly 600.

[0060] When it is necessary to adjust the detection range of the transducer head assembly 200, the driving assembly 600 drives the transducer head assembly 200 to rotate on the transducer head base 500, thereby changing the detection range of the transducer head assembly 200. The handle base 400 not only realizes the function of carrying the compensating member 300, but also realizes the function of carrying the driving assembly 600. By providing the avoidance side 340 on the compensating member 300 and having a gap between the avoidance side 340 and the driving assembly 600, the compensating member 300 can be effectively prevented from interfering with the operation of the driving assembly 600.

[0061] Please refer to Figure 1 、 3 and 4, in one embodiment, the avoidance side 340 includes a first avoidance side 341 and a second avoidance side 342, and the first avoidance side 341, the second avoidance side 342 and the mating side 330 enclose to form a compensation cavity 310.

[0062] The compensation cavity 310 is formed by the enclosure of the first avoidance side 341, the second avoidance side 342 and the mating side 330. A gap is formed between both the first avoidance side 341 and the second avoidance side 342 and the driving assembly 600, thereby preventing the compensating member 300 from interfering with the operation of the driving assembly 600. The mating side 330 is fitted in a shape-conforming manner with the mating portion 120 of the probe housing 100, thereby increasing the utilization rate of the dead space between the mating side 330 and the mating portion 120, and further facilitating an increase in the volume of the compensating member 300.

[0063] Please refer to Figure 1 、 3 and 4, in one embodiment, both the first avoidance side 341 and the second avoidance side 342 are configured as planar structures.

[0064] By configuring both the first avoidance side 341 and the second avoidance side 342 as planar structures, the first avoidance side 341 and the second avoidance side 342 are substantially parallel to the central axis of the probe housing 100, thereby facilitating ensuring that when the compensating member 300 is installed, gaps are formed between both the first avoidance side 341 and the second avoidance side 342 of the compensating member 300 and the driving assembly 600.

[0065] Please refer to Figure 1 、 3And 4. In one embodiment, the shape of the vent 320 is configured as a sector. The first avoidance side 341 and the second avoidance side 342 are respectively located on the two straight sides of the sector, and the mating side 330 is located on the arc side of the sector.

[0066] On the one hand, by respectively arranging the first avoidance side 341 and the second avoidance side 342 on the two straight sides of the sector, the idle space on the handle base 400 where the driving component 600 is not installed can be utilized to the greatest extent, and it is convenient to further set the first avoidance side 341 and the second avoidance side 342 as planar structures. On the other hand, by arranging the mating side 330 on the arc side of the sector, it is convenient to achieve the fit between the mating side 330 and the mating portion 120 of the arc surface structure.

[0067] Please refer to Figure 1 , in one embodiment, the driving component 600 includes a driving motor 610, a transmission member 620, and a driving wheel 630. The driving motor 610 is connected to the handle base 400. One end of the transmission member 620 is connected to the driving motor 610 through the driving wheel 630, and the other end is connected to the sound head assembly 200. The driving motor 610 is used to drive the driving wheel 630 to rotate, so as to drive the sound head assembly 200 to rotate through the transmission member 620.

[0068] When it is necessary to drive the sound head assembly 200 to rotate on the sound head base 500, the driving motor 610 can be used to drive the driving wheel 630 to rotate, and then the driving wheel 630 drives the transmission member 620 to move, and further drives the sound head assembly 200 to rotate through the transmission member 620. Specifically, the transmission member 620 can be a steel wire rope or a transmission belt. The driving wheel 630 can be a wire rope sheave for driving the steel wire rope to move, or a pulley for driving the transmission belt to move. The steel wire rope or the transmission belt can be directly connected or indirectly connected to the sound head assembly 200. For example, it can be indirectly connected through a rotating shaft.

[0069] The above uses specific examples to elaborate on the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the technical field to which the present invention belongs, according to the idea of the present invention, several simple deductions, deformations or substitutions can also be made.
