[0002] In 4D mechanical probes, a stepper motor is typically used to drive the acoustic head to swing within a certain angle, scanning and imaging the human body from multiple angles within this swing range to construct a 3D / 4D image of the human tissue. In 3D mechanical probes, the transmission system generally uses a synchronous belt and steel cable to transmit the motor's motion to the acoustic head, thereby achieving the swinging of the acoustic head. However, whether it's a 4D or 3D mechanical probe, the existing ultrasonic probe structure is not compact enough and can be further optimized. Summary of the Invention

A portion of the probe base protrudes towards the concave space to form a protrusion. At least a portion of the gear transmission assembly is accommodated within the recessed cavity formed by the protrusion. The concave space of the probe head provides a larger space on the side of the probe base facing the probe head, thereby allowing space between the probe base and the probe head to form the protrusion protruding towards the probe head. The cavity formed by the protrusion accommodates a portion of the gear transmission assembly, making the structure between the probe head and the probe head drive assembly more compact, and thus reducing the overall volume and size of the ultrasonic probe.

A portion of the transmission mechanism is housed in the recessed cavity.

[0024] In the ultrasonic probe shown in this embodiment, a concave space is formed on the side of the probe head facing the probe base. A portion of the probe base protrudes towards the concave space to form a protrusion. At least a portion of the transmission mechanism is accommodated within the recessed cavity formed by the protrusion. The concave space of the probe head provides a larger space on the side of the probe base facing the probe head, thereby allowing space between the probe base and the probe head to form the protrusion protruding towards the probe head. The cavity formed by the protrusion accommodates a portion of the transmission mechanism, making the structure between the probe head and the probe head drive assembly more compact, and thus reducing the overall volume and size of the ultrasonic probe.

[0043] In the ultrasonic probe shown in this embodiment, its transmission mechanism includes a synchronous wheel mechanism. The rotation axes of each synchronous wheel, the swing axis, and the rotation axis of the output shaft of the drive motor are parallel to each other. This allows the space between the drive motor, the transmission mechanism, and the probe base to form a mounting cavity for the control unit. The control unit is integrated into the overall structure formed by the drive motor, transmission mechanism, and probe base, improving the overall compactness of the ultrasonic probe and reducing its volume and size. Furthermore, the center distance between the rotation axes of the synchronous wheels in this structure is adjustable. Therefore, the size of the mounting cavity can be adjusted by changing the center distance according to the components to be accommodated within the cavity, allowing for more flexible cavity design.

The gear transmission group is a cylindrical helical gear transmission group or a cylindrical spur gear transmission group.

[0059] In the ultrasonic probe shown in this embodiment, its transmission mechanism includes a synchronous pulley mechanism and a gear transmission group. The rotation axes of the synchronous pulleys in the synchronous pulley mechanism, the rotation axes of the gears in the gear transmission group, the output shaft of the drive motor, and the swing axis are parallel to each other.

[0071] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of this application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to this application are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0072] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0073] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0074] Some embodiments of this application provide an ultrasonic probe, which is a type of probe with a swingable head, such as a 4D mechanical probe or a 3D mechanical probe. The 4D or 3D mechanical probe typically uses a drive motor to drive the head, allowing it to swing within a certain angle and scan the human body at multiple angles within the swing range, thereby constructing a three-dimensional / four-dimensional image of human tissue.

[0075] Please refer to Figure 1-4 In some embodiments, the ultrasonic probe includes a housing 100, a head base 200, a head 300, a head drive assembly 400, and a control unit 500. The control unit 500 may be, but is not limited to, a control circuit board or other structures with control circuitry. The control unit 500 is used to control the head 300 to emit ultrasonic waves and also to form images based on the ultrasonic echoes received by the head 300. Of course, in other embodiments, the ultrasonic probe may also have other components as needed, such as a cable 600 or a cable sheath 700, which will not be elaborated upon here. This application mainly describes content primarily related to the concept of this application.

[0076] The housing 100 serves as a support structure for the ultrasonic probe and also provides a cavity for the probe, which can be used to mount and house the head base 200, the head 300, the head drive assembly 400, and other components. The head base 200, the head 300, and the head drive assembly 400 are directly or indirectly mounted on the housing 100. The housing 100 is typically composed of two or more sub-housings, for example, joined together. Of course, if the manufacturing process allows, the housing 100 can be a single, integrally molded structure, for example, manufactured using 3D printing.

[0077] Please refer to Figure 1 and 2 In some embodiments, the housing 100 includes a main housing 110 and an acoustic window 120. The main housing 110 and the acoustic window 120 can form the aforementioned cavity. The acoustic window 120 is positioned opposite to the acoustic head 300, and its location is where the ultrasonic probe emits and receives ultrasonic waves. The main housing 110 and the acoustic window 120 can also be integrally formed or assembled from multiple parts. Furthermore, where other requirements exist, the housing 100 may also include components other than the main housing 110 and the acoustic window 120, which together with the main housing 110 and the acoustic window 120 constitute the housing 100 of the ultrasonic probe. In some embodiments, such as... Figure 1 As shown, the main housing 110 can serve as a gripping part for the ultrasonic probe when the operator holds it. Therefore, the main housing 110 can have a shape that meets the gripping requirements, such as being concave.

[0078] The head base 200 is used to provide movable support for the head 300, allowing the head 300 to swing on the head base 200. Please refer to... Figure 2-3 In some embodiments, the acoustic head base 200 is located within the housing 100 and forms an acoustic head receiving cavity with the housing 100. The acoustic head 300 is used to transmit and receive ultrasonic signals, and it is disposed in the acoustic head receiving cavity in a swingable manner, for example, it is rotatably connected to the acoustic head base 200.

[0079] The function of the sound head drive assembly 400 is to drive the sound head 300 to oscillate according to a set pattern. Please refer to... Figure 2-4 In some embodiments, the acoustic head drive assembly 400 is installed within the housing 100. The acoustic head drive assembly 400 includes a drive motor 410 and a transmission mechanism 420. The transmission mechanism 420 is connected between the output shaft of the drive motor 410 and the acoustic head 300 to transmit the motion output by the drive motor 410 to the acoustic head 300, thereby driving the acoustic head 300 to oscillate around its oscillation axis. The transmission mechanism 420 and its mating structure with the drive motor 410 can be any structure found in existing ultrasonic probes with an oscillating acoustic head 300, and are not limited to this type. Figure 2-4 The structure shown.

[0080] Please refer to Figure 3 In some embodiments, a coupling fluid is provided within the acoustic head housing cavity. To prevent the coupling fluid from flowing from the acoustic head housing cavity into the space where the drive motor 410 is located, the acoustic head base 200 separates the acoustic head drive assembly 400 from the acoustic head 300. This separation can be achieved through a sealed separation. The acoustic head 300 can be separated by a sealed connection structure penetrating the acoustic head base 200 (e.g., ...). Figure 6 The transmission shaft 910 shown is connected to the transmission mechanism 400.

[0081] To improve the structural compactness of the ultrasonic probe and reduce its overall volume, some embodiments are described below. Figure 3-4 The sound head 300 is recessed inward on the side facing the sound head base 200 to form a concave space. For example, in Figure 4 In the illustrated embodiment, the bottom surface of the sound head 300 in the illustrated direction is recessed into the sound head 300 to form a concave surface 310, which encloses a concave space. A portion of the sound head base 200 protrudes towards the concave space and forms a protrusion 210. A recessed cavity 211 is formed on the side of the protrusion 210 facing the transmission mechanism 420, and a portion of the transmission mechanism 420 is accommodated within the recessed cavity 211. In this embodiment, after the acoustic probe 300 forms a concave space on the side facing the acoustic probe base 200, a larger reserved space is formed between the portion of the acoustic probe base 200 opposite to the concave space and the acoustic probe 300. This allows space to be formed between the acoustic probe base 200 and the acoustic probe 300 to form a protrusion 210 protruding towards the acoustic probe 300. The cavity formed by the protrusion 210 protruding towards the acoustic probe 300 then accommodates part of the transmission mechanism 420, making the structure between the acoustic probe 300 and the acoustic probe drive assembly 400 more compact. The ultrasonic probe in the length direction (i.e., Figure 3-4 The dimensions shown in the diagram (vertical direction) are shorter, thus reducing the overall volume and size of the ultrasound probe.

[0082] In some embodiments, please refer to Figure 3and 4 At least a portion of the protrusion 210 is inserted into the concave space, that is, the protrusion 210 is inserted into the concave space in the front-to-back direction toward the most prominent point of the sound head 300 (in this embodiment, the side where the sound window 120 is located is defined as the front side, and the side where the cable 600 is located is defined as the rear side, and the most prominent point is equivalent to the most front end of the protrusion 210). This structure can more effectively utilize the concave space to accommodate the transmission mechanism 420, reduce the distance between the sound head 300 and the protrusion 210, and thus improve the compactness of the structure.

[0083] In some further embodiments, at least a portion of the outer wall of the protrusion 210 facing the concave surface 310 may also be adapted to the outer wall of the concave surface 310, or to the trajectory surface formed by the swing of the sound head 300 (the side of the sound head 300's movement trajectory facing the protrusion 210), so as to bring the protrusion 210 as close as possible to the sound head 300 without affecting the swing of the sound head 300, thereby providing a more compact structure. This adaptation means that at least a portion of the protrusion 210 facing the concave surface 310 has the same shape as the concave surface 310 or the trajectory surface formed by the swing of the sound head 300. For example, when the concave surface 310 or the trajectory surface is an arc surface or other shape, at least a portion of the protrusion 210 may also be an arc surface or other shape of the same shape.

[0084] Of course, in some other embodiments, the protrusion 210 may not be inserted into the concave space as a whole; that is, the most prominent point of the protrusion 210 is located completely behind the concave space in the anteroposterior direction of the ultrasound probe and does not extend into the concave space. The concave space increases the spatial distance between the head 300 and the head base 200, which is sufficient to allow the head base 200 to form the protrusion 210 in the direction of the head 300 even if the protrusion 210 is not inserted into the concave space.

[0085] Specifically, in some embodiments, please refer to Figure 2 and 5 The sound head base 200 has a separator 220. The separator 220 separates the sound head drive assembly 400 from the sound head 300. The side of the sound head 300 facing the separator 220 is recessed inward to form a concave space, and a portion of the separator 220 protrudes inward toward the concave space to form a protrusion 210. The separator 220 is a partition structure transversely disposed between the sound head 300 and the transmission mechanism 420, and its specific shape can be designed into various shapes and structures according to actual functional requirements.

[0086] Please refer to Figure 2 and 5In some embodiments, the sound head base 200 may further include an annular structure 230 surrounding the partition 220, the annular structure 230 being arranged circumferentially around the partition 220. The annular structure 230 increases the area of ​​the sidewall of the sound head base 200, thereby facilitating easier fixing of the sidewall to the housing 100, for example, by screws, clips, adhesives, or welding. Simultaneously, the increased area of ​​the sidewall also allows for a better sealing connection with the inner wall of the housing 100. Of course, in other embodiments, the sound head base 200 may also adopt other shapes and is not limited to these. Figure 2 and 5 The shape and structure shown.

[0087] Furthermore, in some embodiments, the output shaft of the drive motor 410 is arranged parallel to the swing axis of the sound head 300. Figure 4 In the illustrated embodiment, the drive motor 410 is arranged laterally relative to the housing 100 to shorten the overall length of the ultrasonic probe in the front-to-back direction. Of course, in other embodiments, the drive motor 410 may also be arranged along the front-to-back direction (i.e., the length direction of the ultrasonic probe).

[0088] Furthermore, in some embodiments, please refer to Figure 4 The transmission mechanism 420 includes a synchronizer pulley mechanism 421 and at least one stage gear transmission group 422. The synchronizer pulley mechanism 421 includes a master synchronizer pulley 4211, a slave synchronizer pulley 4212, and a transmission element 4213 disposed between the master synchronizer pulley 4211 and the slave synchronizer pulley 4212. The synchronizer pulley mechanism 421 includes, but is not limited to, at least one of a synchronizer belt drive mechanism and a synchronizer chain drive mechanism. Depending on the specific type of the synchronizer pulley mechanism 421, the type of its transmission element 4213 also varies. For example, as... Figure 4 As shown, when the synchronous pulley mechanism 421 adopts a synchronous belt drive mechanism, the transmission component 4213 is a synchronous belt. When the synchronous pulley mechanism 421 adopts a synchronous chain mechanism, the transmission component 4213 is a synchronous chain. Each stage of gear transmission group 422 includes an input gear 4221 and an output gear 4222 for meshing transmission. There is usually one input gear 4221 in each stage of gear transmission group 422, but in some embodiments there may be two or more. There is usually one output gear 4222 in each stage of gear transmission group 422, but in some embodiments there may be two or more. Figure 4 In the illustrated embodiment, the gear transmission group 422 is a single-stage gear transmission group, achieving single-stage reduction. In other embodiments, the gear transmission group 422 can also be configured with two or more stages, thereby forming multi-stage reduction. When the gear transmission group 422 is multi-stage, along the direction of motion transmission, the gear transmission group 422 located at the forefront of the transmission direction is the first-stage gear transmission group, and the gear transmission group 422 located at the rearmost end of the transmission direction is the last-stage gear transmission group. When the gear transmission group 422 has only one stage (e.g.... Figure 4 As shown in the figure, at this time, the first stage gear transmission group is also the last stage gear transmission group.

[0089] Please refer to Figure 4 In this embodiment, the main synchronous pulley 4211 of the synchronous pulley mechanism 421 is fixed to the output shaft of the drive motor 410. The driven synchronous pulley 4212 of the synchronous pulley mechanism 421 is coaxially fixed to the input gear 4221 of the first-stage gear transmission group (i.e., gear transmission group 422). The output gear 4222 of the last-stage gear transmission group (i.e., gear transmission group 422) is connected to the sound head 300 to drive the sound head 300 to swing. In this embodiment, the synchronous pulley mechanism 421 is connected to the drive motor 410 (i.e., a connection capable of transmitting motion and force), and the last-stage gear transmission group is connected to the sound head 300.

[0090] Of course, in other embodiments, the first-stage gear transmission group can be connected to the drive motor 410 (i.e., a connection capable of transmitting motion and force), and the synchronous pulley mechanism 421 can be connected to the sound head 300. Specifically, in some embodiments, the output shaft of the drive motor 410 is fixed or meshed with the input gear 4221 of the corresponding gear transmission group 422, the output gear 4222 of the last-stage gear transmission group is connected to the main synchronous pulley 4211 of the synchronous pulley mechanism 421, and the slave synchronous pulley 4212 of the synchronous pulley mechanism 421 is connected to the sound head 300 to drive the sound head 300 to swing.

[0091] In the above embodiments, when the transmission mechanism 420 includes a synchronous pulley mechanism 421 and at least one stage gear transmission group 422, specifically, a part of the gear transmission group 422 (such as the output gear 4222) may extend into the recessed cavity 211, or a part of the synchronous pulley mechanism 421 (such as the driven pulley) may extend into the recessed cavity 211.

[0092] Furthermore, such as Figure 4 As shown, when the transmission mechanism 420 includes a synchronous pulley mechanism 421 and at least one stage gear transmission group 422, the rotation axis of the main synchronous pulley 4211, the rotation axis of the secondary synchronous pulley 4212, the rotation axis of the input gear 4221, the rotation axis of the output gear 4222, the rotation axis of the output shaft of the drive motor 410, and the swing axis of the ultrasound head 300 are parallel to each other, thus forming a structure in which the drive motor 410 is placed laterally, the synchronous pulley mechanism 421 is arranged along the front-back direction of the probe, and the gear transmission group 422 is also arranged along the front-back direction of the probe. This layout structure can make the structure of the entire ultrasound head drive assembly 400 more compact, which is beneficial to reducing the volume and size of the ultrasound probe.

[0093] Further, please refer to Figure 4In some embodiments, the gear transmission assembly 422 is a cylindrical helical gear transmission assembly or a cylindrical spur gear transmission assembly, that is, the gears in the gear transmission assembly 422 are cylindrical helical gears or cylindrical spur gears. Compared with other wire ropes or other transmission structures, this cylindrical helical gear transmission assembly or cylindrical spur gear transmission assembly has higher transmission accuracy and lower processing cost.

[0094] For the arrangement of the gear transmission assembly 422 and the synchronous pulley mechanism 421, please refer to... Figure 4 In some embodiments, the input gear 4221 and the drive motor 410 are located on both sides of the synchronous pulley mechanism 421 in the transverse direction. The transverse direction of the synchronous pulley mechanism 421 refers to the direction along the rotation axis of each synchronous pulley, that is... Figure 4 The drive motor 410 is shown axially, and the drive motor 410 and the input gear 4221 are located on the left (or right) and right (or left) sides of the synchronous pulley mechanism 421, respectively. In this structure, a space can be formed between the area below the input gear 4221 and the right (or left) side of the synchronous pulley mechanism 421, which can be used to place other components to increase the compactness of the structure.

[0095] Please refer to Figure 6 In other embodiments, the input gear 4221 and the drive motor 410 are located on the same side of the synchronous gear mechanism 421 in the transverse direction. That is... Figure 6 Along the axial direction of the drive motor 410, the input gear 4221 and the drive motor 410 are simultaneously located on the left (or right) side of the synchronous pulley mechanism 421. In this structure, the entire gear transmission assembly 422 is located on the left side of the entire synchronous pulley mechanism 421, making full use of the space on the left side of the synchronous pulley mechanism 421, resulting in a more compact structure. The space on the right side of the synchronous pulley mechanism 421 is left free, which can be used to place other components to save space in other locations and improve the compactness of the structure. Alternatively, no components may be provided, thereby reducing the size of the ultrasonic probe in the lateral direction of the synchronous pulley mechanism 421.

[0096] Furthermore, the transmission mechanism 420 can be directly or indirectly mounted on the housing 100. Please refer to [reference needed]. Figure 4 and 5In some embodiments, the sound head drive assembly 400 includes a support assembly 800. The support assembly 800 is fixedly connected to the housing 100 and has a main synchronous pulley mounting cavity 810 and a driven synchronous pulley mounting cavity 820. The main synchronous pulley 4211 of the synchronous pulley mechanism 421 is located in the main synchronous pulley mounting cavity 810, and the driven synchronous pulley 4212 of the synchronous pulley mechanism 421 is located in the driven synchronous pulley mounting cavity 820. The drive motor 410 is fixedly mounted on the support assembly 800, and the output shaft of the drive motor 410 extends into the main synchronous pulley mounting cavity 810 and is fixedly connected to the main synchronous pulley 4211. The input gear 4221 of the gear transmission set 422 is located in the driven synchronous pulley mounting cavity 820 and is coaxially fixedly connected to the driven synchronous pulley 4212. Of course, the synchronous pulley mechanism 421 and the gear transmission set 422 can also be mounted on the housing 100 using other structures.

[0097] Of course, in other embodiments of the transmission mechanism 420, the transmission mechanism 420 may also include at least one stage of the aforementioned gear transmission group 422. In this case, the transmission mechanism 420 may or may not include the aforementioned synchronous pulley mechanism 421. In order to form a more compact transmission mechanism 420 that can utilize the space in the front-back direction of the probe, in some embodiments, the rotation axis of each gear in the gear transmission group 422, the swing axis of the sound head 300, and the rotation axis of the output shaft of the drive motor 410 are parallel to each other, thereby forming a compact structure in which the drive motor 410 is arranged laterally and the gear transmission group 422 is arranged along the front-back direction of the probe.

[0098] Furthermore, in some embodiments of the transmission mechanism 420, the transmission mechanism 420 includes the aforementioned synchronous pulley mechanism 421. In this case, the transmission mechanism 420 may or may not include the aforementioned gear transmission assembly 422. In order to form a more compact transmission mechanism 420 that can utilize the space in the probe's front-back direction, in some embodiments, the rotation axis of each synchronous pulley in the synchronous pulley mechanism 421 is parallel to the swing axis and the rotation axis of the output shaft of the drive motor 410, thereby forming a compact structure in which the drive motor 410 is arranged laterally and the synchronous pulley mechanism 421 is arranged along the probe's front-back direction.

[0099] On the other hand, in order to form a more compact probe structure and thus reduce the overall volume of the ultrasonic probe, some embodiments of this application also provide another ultrasonic probe. Please refer to... Figure 1 and 2In some embodiments, the ultrasonic probe includes components such as a housing 100, a head base 200, a head 300, and a head drive assembly 400. The head base 200 is located within the housing 100 and forms a head receiving cavity with the housing 100. The head 300 is used to emit and receive ultrasonic signals and is disposed within the head receiving cavity in a swingable manner. The head drive assembly 400 is installed within the housing 100 and includes a drive motor 410 and a transmission mechanism 420. The drive motor 410 is located on the side of the head base 200 opposite to the head 300, and the transmission mechanism 420 is connected between the output shaft of the drive motor 410 and the head 300 to drive the head 300 to swing around its swing axis.

[0100] Please refer to Figure 4 and 6 In this embodiment, the transmission mechanism 420 includes a synchronous pulley mechanism 421. The rotation axis, swing axis and output shaft of each synchronous pulley in the synchronous pulley mechanism 421 are parallel to each other. A mounting cavity A for mounting the control unit 500 (such as a control circuit board) is formed between the drive motor 410, the transmission mechanism 420 and the head base 200.

[0101] In the ultrasonic probe shown in this embodiment, a mounting cavity A for mounting the control unit 500 is formed by utilizing the space between the drive motor 410, the transmission mechanism 420, and the acoustic head base 200. The control unit 500 is integrated into the overall structure formed by the drive motor 410, the transmission mechanism 420, and the acoustic head base 200. The control unit 500 is mounted using the existing gap between the drive motor 410, the transmission mechanism 420, and the acoustic head base 200, thereby improving the structural compactness of the entire ultrasonic probe. Consequently, there is no need to reserve mounting space for the control unit 500 in other parts, reducing the overall volume and size of the ultrasonic probe. Moreover, the center distance between the rotation axes of the synchronous pulleys of the synchronous pulley mechanism 421 in this structure is adjustable. Therefore, the size of the mounting cavity A can be adjusted by adjusting the center distance according to the size of the component to be accommodated in the mounting cavity A. This allows for more flexible setting of the size of the mounting cavity A without affecting the transmission ratio of the transmission mechanism 420, thus accommodating objects of different sizes.

[0102] In this embodiment, the housing 100, the sound head 300, the sound head base 200, and the sound head driving assembly 400 can adopt the structures shown in the foregoing embodiments. For example, the sound head 300 may have a concave space, the sound head base 200 may have a protrusion 210, and the transmission mechanism 420 of the sound head driving assembly 400 can be partially accommodated in the recessed cavity 211 of the protrusion 210. For example, please refer to... Figure 4In some embodiments, the sound head base 200 has a partition 220 that separates the sound head drive assembly 400 from the sound head 300; the sound head 300 is recessed inward on the side facing the partition 220 to form a concave space, a portion of the partition 220 protrudes in the direction of the concave space to form a protrusion 210, and the side of the protrusion 210 facing the transmission mechanism 420 forms a recessed cavity 211, a portion of the transmission mechanism 420 is accommodated in the recessed cavity 211.

[0103] Of course, since the drive motor 410, the transmission mechanism 420 and the sound head base 200 form a mounting cavity A for mounting the control unit 500, this structure has improved the compactness of the structure to a certain extent. Therefore, in some other embodiments, the sound head 300 may not have a recessed space, and the sound head base 200 may not have a protrusion 210.

[0104] Furthermore, in some embodiments, the sound head 300, the sound head base 200, and the sound head drive assembly 400 may also adopt some of the structures shown in the prior art, provided that the mounting cavity A can be formed as described above.

[0105] In some more specific embodiments, the transmission mechanism 420 has at least one gear transmission group 422, and the synchronizing pulley mechanism 421 is connected to the gear transmission group 422 in a transmission manner. A portion of the gear transmission group 422 or a portion of the synchronizing pulley mechanism 421 extends into the recessed cavity 211.

[0106] Alternatively, in some more specific embodiments, the transmission mechanism 420 includes at least one gear transmission group 422, in which the rotation axis of the gears is parallel to the swing axis of the head 300 and the output shaft of the drive motor 410.

[0107] Furthermore, in order to form a more compact probe structure and thus reduce the overall size of the ultrasonic probe, some embodiments of this application also provide another type of ultrasonic probe. Please refer to... Figure 1 and 2 In some embodiments, the ultrasonic probe includes a housing 100, a head base 200, a head 300, and a head drive assembly 400. The head base 200 is located inside the housing 100 and forms a head receiving cavity with the housing 100; the head 300 is used to emit and receive ultrasonic signals and is disposed in the head receiving cavity in a swingable manner; the head drive assembly 400 is installed inside the housing 100 and includes a drive motor 410 and a transmission mechanism 420, with the drive motor 410 located on the side of the head base 200 away from the head 300.

[0108] Please refer to the following: Figure 4 and 6The transmission mechanism 420 is connected between the output shaft of the drive motor 410 and the sound head 300. The transmission mechanism 420 includes a synchronous pulley mechanism 421 and a gear transmission group 422. The synchronous pulley mechanism 421 and the gear transmission group 422 form a transmission connection to drive the sound head 300 to swing around its swing axis. The rotation axes of each synchronous pulley in the synchronous pulley mechanism 421, the rotation axes of each gear in the gear transmission group 422, the output shaft of the drive motor 410, and the swing axis are parallel to each other. The gear transmission group 422 is a cylindrical helical gear transmission group or a cylindrical spur gear transmission group.

[0109] In the ultrasonic probe shown in this embodiment, the rotation axes of the synchronous pulleys in the synchronous pulley mechanism 421, the rotation axes of the gears in the gear transmission group 422, the output shaft of the drive motor 410, and the swing axis are parallel to each other. This layout structure makes the entire ultrasonic head drive assembly 400 more compact, which is beneficial for reducing the volume and size of the ultrasonic probe. Moreover, the transmission mechanism 420 adopts a combination of the synchronous pulley mechanism 421 and a cylindrical helical gear transmission group or a cylindrical spur gear transmission group, which simplifies the transmission structure. Compared with the traditional steel wire rope or other gear transmission structures, the cylindrical helical gear transmission group or cylindrical spur gear transmission group has higher transmission accuracy and lower processing cost.

[0110] Furthermore, in other further embodiments, the housing 100, the head base 200, the head 300, and the head driving assembly 400 may adopt the structures shown in the foregoing embodiments. Of course, in other embodiments, the housing 100, the head base 200, the head 300, and the head driving assembly 400 may also adopt other structures.

[0111] In some more specific embodiments, please refer to Figure 4 The synchronizing pulley mechanism 421 includes a main synchronizing pulley 4211, a driven synchronizing pulley 4212, and a transmission component 4213 disposed between the main synchronizing pulley 4211 and the driven synchronizing pulley 4212. The main synchronizing pulley 4211 is coaxially fixed with the output shaft of the drive motor 410. The gear transmission group 422 includes an input gear 4221 and an output gear 4222 that mesh with each other. The input gear 4221 is coaxially fixed with the driven synchronizing pulley 4212. In the transverse direction of the synchronizing pulley mechanism 421, the input gear 4221 and the drive motor 410 are respectively located on both sides of the synchronizing pulley mechanism 421.

[0112] Furthermore, in some other embodiments, the input gear 4221 and the drive motor 410 are located on the same side of the synchronous gear mechanism 421 in the transverse direction of the synchronous gear mechanism 421.

[0113] Some embodiments of this application also provide an ultrasound device, which includes an ultrasound host and an ultrasound probe as shown in any of the above embodiments. The ultrasound host has a main control unit for controlling the operation of the ultrasound probe. For example, the main control unit can communicate with the control unit 500 of the ultrasound probe via wired or wireless means to exchange signals.

[0114] The ultrasonic device shown in this embodiment has the various ultrasonic probe structures described above. These ultrasonic probes have a more compact structure and smaller size, which improves the ease of use of the ultrasonic probes.

[0115] The above examples illustrate the present invention only to aid in understanding it and are not intended to limit the scope of the invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the principles of this invention.
