[0038] The utility model discloses a 4D ultrasonic probe, which is convenient for an operator to hold and use.

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] like Figure 1 As shown, an embodiment of the utility model provides a 4D ultrasound probe, including a first base 2, an acoustic function module 1, a driving device 4, a transmission device 6, a handle housing and a circuit board assembly, wherein the first base 2 has a first side and a second side opposite to each other; the acoustic function module 1 includes a transducer, which is rotatably arranged on the first side of the first base 2; the driving device 4 is arranged on the second side of the first base 2, and a first gap is provided between the driving device 4 and the first base 2; the transmission device 6 is arranged on the first base 2 and transmission-connects the driving end of the driving device 4 and the transducer, and the transmission device 6 has a transmission part located on the second side of the first base 2; the handle housing is located on the second side of the first base 2 and is connected to the first base 2, and the transmission part and the inner wall of the handle housing enclose the first gap to form a first accommodation space; the circuit board assembly includes at least two boards 3 in a relatively placed state, and the circuit board assembly is arranged in the first accommodation space.

[0041] The 4D ultrasonic probe provided by the embodiment of the utility model has a first gap between the driving device 4 and the first base 2 due to the setting of the transmission device 6, and the transmission part and the inner wall of the handle shell enclose the first gap to form a first accommodation space. By setting the circuit board assembly as at least two boards 3, at least two boards 3 are arranged in a relative state, so as to match the structure of the first accommodation space, so as to further improve the structural compactness of the circuit board assembly and avoid the excessive size of the circuit board assembly in a single direction; and by setting the circuit board assembly in the first accommodation space, the compactness between the first base 2, the circuit board assembly and the driving device 4 is improved, so as to reduce the space requirement for accommodating parts in the handle shell, so as to reduce the size of the handle shell, thereby reducing the overall size of the 4D ultrasonic probe, so as to facilitate the operator to use it by hand.

[0042] It should be noted that the first accommodation space formed by the first gap enclosed by the inner wall of the transmission part and the handle shell is not a closed space, but a first accommodation space is formed between the drive device 4, the first base 2, the transmission part and the inner wall of the handle shell based on the arrangement of components.

[0043] It can be understood that the housing of the 4D ultrasound probe may include an acoustic window and a handle housing, the acoustic window may be located on the first side of the first base 2 and connected to the first base 2, and the transducer is located in the acoustic window.

[0044] Among them, the connection between the acoustic window and the first base 2 can be provided with a plug-in slot or a glue storage slot or other structures, so as to ensure the sealing effect between the acoustic window and the first base 2, and prevent impurities such as gel or external dust from entering the acoustic window during the use of the 4D ultrasonic probe. Similarly, the connection between the handle shell and the first base 2 can be provided with a plug-in slot or a glue storage slot or other structures, so as to ensure the sealing effect between the handle shell and the first base 2, so as to ensure effective protection of the components (drive device 4 and circuit board assembly) in the handle shell.

[0045] like Figure 1 In the first embodiment, at least two boards 3 in a relative placement state in the circuit board assembly are arranged along the first direction Z, that is, the relative placement state is arranged along the first direction Z. The first direction Z is the arrangement direction of the first base 2 and the driving device 4. Since the thickness dimension of the board 3 is generally the minimum dimension of the board 3, and the thickness dimension of the board 3 is smaller than the length dimension and the width dimension of the board 3, by arranging at least two boards 3 along the first direction Z, the number of boards 3 can be adjusted according to the size of the first gap and the thickness of the board 3, so as to facilitate the design of the circuit board assembly and the assembly of the 4D ultrasound probe.

[0046] like Figure 2 and Figure 3 As shown, in the second embodiment, at least two boards 3 in a relative arrangement state in the circuit board assembly are arranged along the second direction Y, and the second direction Y is perpendicular to the arrangement direction of the first base 2 and the driving device 4. In this embodiment, the axes of the board 3 and the driving end of the driving device 4 are parallel. Through the above arrangement, the width direction of the board 3 is the dimension direction of the first gap.

[0047] Preferably, the number of boards 3 can be adjusted according to the thickness of the boards 3 and the size of the main body of the driving device 4 in the second direction Y to ensure that the outermost boards 3 do not exceed the outer surface of the main body of the driving device 4 in the second direction Y.

[0048] Of course, the board card 3 and the drive end axis of the drive device 4 can also be made perpendicular.

[0049] It is also possible to arrange some of the boards 3 in the circuit board assembly along the first direction Z, and the other part along the second direction Y. Alternatively, the boards 3 in the circuit board assembly are arranged along a third direction, and the angles between the third direction and the first direction Z and the second direction Y are all acute angles.

[0050] In the 4D ultrasound probe provided by the embodiment of the utility model, at least two boards 3 in the circuit board assembly are stacked. That is, two adjacent boards 3 are in contact, or two adjacent boards 3 are supported by a support member. Through the above arrangement, the structural compactness of the circuit board assembly can be further improved.

[0051] Of course, the boards 3 in the circuit board assembly can also be relatively separated and connected via transmission components (such as cables, etc.).

[0052] like Figure 1 As shown, the transmission part is located on one side of the driving device 4, and the driving end of the driving device 4 is located at one end of the main body of the driving device 4 facing the transmission part. Through the above arrangement, the outer peripheral surface of the main body of the driving device 4 faces the first base 2, the circuit board assembly can be located on the side of the outer peripheral surface of the main body of the driving device 4 facing the first base 2, and the transmission part is located outside the first gap, thereby expanding the size of the first accommodation space. Through the above arrangement, the orthographic projection of the transmission part to the second side of the first base 2 and the orthographic projection of the main body of the driving device 4 to the second side of the first base 2 are relatively independent or partially overlapped.

[0053] It is also possible to make the driving end of the driving device 4 face the first base 2, and the driving end of the driving device 4 is also located in the first gap.

[0054] Preferably, the arrangement direction of the main body of the driving device 4 and the driving end of the driving device 4 is perpendicular to the first direction Z; the first direction Z is the arrangement direction of the first base 2 and the driving device 4. Figure 1 Through the above arrangement, when the arrangement direction of the first base 2 and the driving device 4 is vertically arranged, the center line of the driving device 4 is horizontally arranged relative to the surface of the second side of the first base 2, so as to form a first gap with a constant size, which is more convenient for placing multiple boards 3 in the circuit board assembly.

[0055] The surface of the driving device 4 facing the first base 2 can be used to support and fix the circuit board assembly, and the surface of the second side of the first base 2 can also be used to support and fix the circuit board assembly.

[0056] The 4D ultrasound probe provided in the embodiment of the utility model further includes a second base 5, which is arranged on the second side of the first base 2 and connected to the first base 2; the main body of the driving device 4 is arranged on the second base 5. The second base 5 is arranged to facilitate the installation of the driving device 4.

[0057] The driving device 4 is preferably a motor. By providing the second base 5, the existing motor can be directly used as the driving device 4 in the 4D ultrasound probe. The structure of the driving device 4 can also be adjusted to connect it to the first base 2 or the handle housing.

[0058] Furthermore, the main body of the driving device 4 can be adjustably arranged on the second base 5 along the first direction Z; the first direction Z is the arrangement direction of the first base 2 and the driving device 4. That is, the first gap between the driving device 4 and the first base 2 needs to be adjusted according to the actual thickness of the circuit board assembly (the size of the multiple boards 3 in the stacking direction). While ensuring the space requirements of the circuit board assembly, the structure of the transmission device 6 can be appropriately adjusted (such as adjusting the position of the transmission device 6 on the first base 2 and the transmission ratio of the transmission device 6). The length and width of the circuit board assembly (board 3) can be adjusted according to the length and width of the first base 2 and the driving device 4 to ensure that the space volume required to accommodate the circuit board assembly and the driving device 4 is reduced as much as possible, so as to reduce the size design of the handle shell and reduce the size of the 4D ultrasound probe.

[0059] For the convenience of arrangement, the transmission part is arranged on the second base 5. The transmission device 6 includes components such as a gear assembly and a transmission belt. The transmission part is located on the second side of the first base 2, and the transmission part may include a gear and a transmission belt, wherein the transmission belt is connected between the gear and the driving end of the driving device 4, and the gear can be rotatably arranged on the second base 5. Through the above arrangement, the structural stability of the transmission part in the handle housing is improved.

[0060] In order to further optimize the structure, the orthographic projection of the board card 3 to the second side surface of the first base 2 is located inside the second side surface of the first base 2. Through the above arrangement, the structural adjustment of the handle housing is avoided.

[0061] The orthographic projection of the board 3 onto the second side surface of the first base 2 can also be located within the orthographic projection area of ​​the drive device 4 onto the second side surface of the first base 2. The above arrangement prevents the board 3 from extending out of the outer peripheral surface of the drive device 4 in a direction perpendicular to the orthographic projection.

[0062] In this embodiment, the board 3 has a first connection portion that can be electrically connected to the acoustic function module 1, wherein the first connection portion can be a socket or a pad, etc. The first connection portion can be connected to the acoustic function module 1 through a transmission component such as a transmission cable.

[0063] The board 3 has a second connection portion that can be electrically connected to other boards 3 in the circuit board assembly. Similarly, the second connection portion can be a socket or a pad, etc. Preferably, the second connection portion is a socket, and the second connection portions of two adjacent boards 3 can be connected relative to each other.

[0064] The board 3 has a third connection portion that can be electrically connected to a cable, wherein the cable can be electrically connected to an ultrasound device connected to a 4D ultrasound probe.

[0065] For the convenience of processing, all the boards 3 in the circuit board assembly have the same size, that is, the length and width of the boards 3 are the same, so that all the boards 3 can be aligned and arranged.

[0066] The sizes of some boards 3 in the circuit board assembly may be the same, and the sizes of the boards 3 in the circuit board assembly may be different. No detailed description is given and they are all within the scope of protection.

[0067] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0068] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
