Description

Medical ultrasound probes, ultrasound head modules and ultrasound equipment Technical Field

[0001] This application relates to the field of medical devices, specifically to the structure of a medical ultrasound probe. Background Technology

[0002] Medical ultrasound probes are important components of ultrasound equipment (such as ultrasound diagnostic imaging equipment). Their working principle is to use the piezoelectric effect to convert the excitation electrical pulse signal of the whole ultrasound machine into an ultrasonic signal that enters the patient's body, and then convert the ultrasonic echo signal reflected by the tissue into an electrical signal, thereby realizing the detection of the tissue.

[0003] However, existing medical ultrasound probes have a relatively limited detection depth in the target area, making it difficult to obtain richer information for doctors to refer to. Summary of the Invention

[0004] One of the purposes of this application is to provide a medical ultrasound probe, a head module, and an ultrasound device that can detect different depths of the same target area.

[0005] To achieve the above objectives, some embodiments of this application provide a medical ultrasound probe, including a probe control unit and a head segment for insertion into the body cavity of a target. The head segment has a head base, a first head, and a second head. The first head and the second head are both located on the outer side of the head base, so that the first head and the second head can be directed toward the same detection area by changing the position of the head base. The first head and the second head have different center frequencies, so that the first head and the second head can detect different depths.

[0006] Both the first and second acoustic probes are communicatively connected to the probe control unit; the medical ultrasound probe has a first detection mode and a second detection mode; in the first detection mode, the probe control unit controls the first acoustic probe to emit an ultrasound signal for detection; in the second detection mode, the probe control unit controls the second acoustic probe to emit an ultrasound signal for detection.

[0007] According to the medical ultrasound probe shown in the above embodiment, the probe segment simultaneously has a first acoustic head and a second acoustic head. Both the first and second acoustic heads are located on the outer surface of the probe base. Therefore, the operator can change the position of the probe base to make the first and second acoustic heads face the same detection area sequentially. Furthermore, the medical ultrasound probe has a first detection mode and a second detection mode. In the first detection mode, the probe control unit can control the first acoustic head to emit an ultrasound signal towards the same detection area for detection; in the second detection mode, the probe control unit can control the second acoustic head to emit an ultrasound signal towards the same detection area for detection. Because the center frequencies of the first and second acoustic heads are different, the first and second acoustic heads can detect the same detection area sequentially, and the depth of detection of the same detection area is different.

[0008] In some embodiments, in the first detection mode, the probe control unit controls the second acoustic head not to emit ultrasonic signals for detection; in the second detection mode, the probe control unit controls the first acoustic head to emit ultrasonic signals for detection.

[0009] In some embodiments, the first sound head and the second sound head are located at different positions in the circumferential direction of the sound head base, and when the sound head base is static, the emitting surfaces of the first sound head and the second sound head face different detection directions, so that when the sound head base rotates, the emitting surfaces of the first sound head and the second sound head can face the same detection area one after the other.

[0010] In some embodiments, at least a portion of the emitting surfaces of the first and second sound heads are located along the same length segment in the axial direction of the sound head base.

[0011] In some embodiments, the emitting surfaces of the first and second sound heads are located on the same length segment along the axial direction of the sound head base; or, the length segment containing the emitting surface of the first sound head is located within the length segment containing the emitting surface of the second sound head along the axial direction of the sound head base; or, the length segment containing the emitting surface of the second sound head is located within the length segment containing the emitting surface of the first sound head along the axial direction of the sound head base.

[0012] In some embodiments, the emitting surfaces of the first and second sound heads are circumferentially opposite to each other on the sound head base.

[0013] In some embodiments, the first sound head and the second sound head are located at different positions along the axial direction of the sound head base, so that when the sound head base moves along its axial direction, the emitting surfaces of the first sound head and the second sound head can face the same detection area sequentially.

[0014] In some embodiments, the emitting surfaces of the first and second sound heads are located in the same circumferential direction of the sound head base.

[0015] In some embodiments, the first sound head is located in front of the second sound head in the axial direction of the sound head base.

[0016] In some embodiments, the first acoustic head is a convex array acoustic head, and the second acoustic head is a linear array acoustic head.

[0017] In some embodiments, the center frequency of the first microphone is 5-10 MHz, and the center frequency of the second microphone is 12-20 MHz.

[0018] Based on the above objectives, some embodiments of this application provide a medical ultrasound probe, including a probe control unit and a head segment for insertion into the body cavity of the object being tested. The head segment has a head base, a first head, and a second head. The first head and the second head are both located on the outer side of the head base, and the center frequencies of the first head and the second head are different, so that the first head and the second head can detect different depths.

[0019] According to the medical ultrasound probe shown in the above embodiment, the probe segment simultaneously has a first acoustic head and a second acoustic head. Both the first and second acoustic heads are located on the outer surface of the probe base. Therefore, the operator can change the position of the probe base to make the first and second acoustic heads face the same detection area sequentially, thus enabling sequential detection of the same detection area. Furthermore, the first and second acoustic heads have different center frequencies, allowing them to detect different depths within the same detection area.

[0020] In some embodiments, the first sound head and the second sound head are located at different positions in the circumferential direction of the sound head base, and when the sound head base is static, the emitting surfaces of the first sound head and the second sound head face different detection directions, so that when the sound head base rotates, the emitting surfaces of the first sound head and the second sound head can face the same detection area one after the other.

[0021] In some embodiments, at least a portion of the emitting surfaces of the first and second sound heads are located along the same length segment in the axial direction of the sound head base.

[0022] In some embodiments, the emitting surfaces of the first and second sound heads are circumferentially opposite to each other on the sound head base.

[0023] In some embodiments, the first sound head and the second sound head are located at different positions along the axial direction of the sound head base, so that when the sound head base moves along its axial direction, the emitting surfaces of the first sound head and the second sound head can face the same detection area sequentially.

[0024] In some embodiments, the emitting surfaces of the first and second sound heads are located in the same circumferential direction of the sound head base.

[0025] In some embodiments, the first sound head is located in front of the second sound head in the axial direction of the sound head base.

[0026] In some embodiments, the first acoustic head is a convex array acoustic head, and the second acoustic head is a linear array acoustic head; or, the first acoustic head is a linear array acoustic head, and the second acoustic head is a convex array acoustic head.

[0027] In some embodiments, the center frequency of the first sound head is 5-10MHz and the center frequency of the second sound head is 12-20MHz; or, the center frequency of the first sound head is 12-20MHz and the center frequency of the second sound head is 5-10MHz.

[0028] Based on the above objectives, some embodiments of this application provide a sound head module for a medical ultrasound probe, including at least one first sound head unit and at least one second sound head unit; the first sound head unit includes a first backing layer, a first positive electrode lead-out circuit layer, a first array element layer, a first negative electrode lead-out circuit layer and a first matching layer arranged sequentially, and the second sound head unit includes a second backing layer, a second positive electrode lead-out circuit layer, a second array element layer, a second negative electrode lead-out circuit layer and a second matching layer arranged sequentially, wherein the center frequencies applicable to the first array element layer and the second array element layer are different;

[0029] The first and second sound head units are arranged side by side, and the first and second backing layers are an integral structure.

[0030] According to the ultrasound probe module shown in the above embodiment, the first array element layer and the second array element layer have different applicable center frequencies, thus enabling detection at different depths of the same detection area. The resulting images originate from tissues at different depths, and therefore the image content is also different, allowing for a more comprehensive examination of organs to assist doctors in making diagnoses. Moreover, unlike other methods that simultaneously set at least two ultrasound probes, this ultrasound probe module integrates two ultrasound probe units, and its first and second backing layers are a single structure. This not only enables detection of tissues at different depths within the detection area but also allows for a more compact ultrasound probe.

[0031] In some embodiments, there are at least two first sound head units, wherein the two first sound head units are symmetrically arranged on both sides of at least one second sound head unit, such that, in a static state, the detection area of ​​the second sound head unit located between the two first sound head units can at least partially overlap with the detection areas corresponding to the two first sound head units.

[0032] In some embodiments, at least one first positive lead-out circuit layer of a first sound head unit and at least one second positive lead-out circuit layer of a second sound head unit are integral structures.

[0033] And / or, at least one first negative lead-out circuit layer of a first sound head unit and at least one second negative lead-out circuit layer of a second sound head unit are integral structures.

[0034] In some embodiments, the thicknesses of the first array element layer and the second array element layer are different, wherein:

[0035] At least one first sound head unit has a position compensation member on the positive and / or negative electrode surface of the first element layer, the position compensation member being a conductive material, so that the positive and / or negative electrode surface of the first sound head unit can be flush with the positive and / or negative electrode surface of the second element layer of at least one second sound head unit.

[0036] And / or, at least one second acoustic head unit has a position compensation element on the positive and / or negative electrode surface of the second element layer, the position compensation element being a conductive material, so that the positive and / or negative electrode surface of the second acoustic head unit can be flush with the positive and / or negative electrode surface of the first element layer of at least one first acoustic head unit.

[0037] In some embodiments, the thicknesses of the first array element layer and the second array element layer are different, wherein the first backing layer of at least one first sound head unit protrudes relative to the second backing layer of at least one second sound head unit, or the second backing layer of at least one second sound head unit protrudes relative to the first backing layer of at least one first sound head unit, such that the positive electrode surface of the first array element layer of the first sound head unit is flush with the positive electrode surface of the second array element layer of the second sound head unit.

[0038] In some embodiments, at least one of the first negative lead-out circuit layer, the first array element layer, the first positive lead-out circuit layer, and the first matching layer of the first sound head unit is an independent structure;

[0039] And / or, at least one of the second negative lead-out circuit layer, the second array element layer, the second positive lead-out circuit layer, and the second matching layer of the second sound head unit is an independent structure.

[0040] Based on the above objectives, some embodiments of this application provide an ultrasonic probe head module, including at least one first acoustic head unit and at least one second acoustic head unit; the first acoustic head unit includes a first array element layer, and the second acoustic head unit includes a second array element layer; the first acoustic head unit and the second acoustic head unit can independently perform ultrasonic detection, and the center frequencies applicable to the first array element layer and the second array element layer are different; the first acoustic head unit and the second acoustic head unit are independent of each other and arranged side by side.

[0041] According to the ultrasound probe module shown in the above embodiment, the first and second ultrasound probe units have different center frequencies, thus enabling detection at different depths within the same detection area. The resulting images originate from tissues at different depths, and therefore the image content is also different, allowing for a more comprehensive examination of organs and assisting doctors in making diagnoses. Furthermore, unlike modules that simultaneously use at least two ultrasound probes, this ultrasound probe module integrates two ultrasound probe units, with the first and second units arranged side-by-side. This improves the overall structural compactness of the ultrasound probe module, enabling detection of tissues at different depths within the detection area while also making the ultrasound probe more compact. Moreover, the first and second ultrasound probe units are independent and can be manufactured separately, simplifying the manufacturing process.

[0042] In some embodiments, there are at least two first sound head units, wherein the two first sound head units are symmetrically arranged on both sides of at least one second sound head unit, such that, in a static state, the detection area of ​​the second sound head unit located between the two first sound head units can at least partially overlap with the detection areas corresponding to the two first sound head units.

[0043] In some embodiments, the thicknesses of the first array element layer and the second array element layer are different, and the emitting surfaces of the first sound head unit and the second sound head unit are flush.

[0044] For the above purposes, some embodiments of this application provide a medical ultrasound probe, including:

[0045] Probe housing;

[0046] And a head module as described in any of the above, the head module being mounted on the probe housing.

[0047] For the above purposes, some embodiments of this application provide a medical ultrasound probe, including:

[0048] Probe housing;

[0049] At least one first acoustic head, which is mounted on the probe housing;

[0050] At least one second acoustic head is mounted on the probe housing. The first acoustic head and the second acoustic head have different center frequencies, so that the first acoustic head and the second acoustic head can detect different depths.

[0051] The device also includes a switching mechanism that can switch the position of the first sound head and / or the second sound head between a detection position and a non-detection position, so that the operator can control the emitting surfaces of the first sound head and the second sound head to face the same detection area sequentially.

[0052] The medical ultrasound probe described in the above embodiment can switch the position of the first and / or second ultrasound head between a detection position and a non-detection position via a switching device. This allows the first and second ultrasound heads to face the same detection area sequentially. Because the center frequencies of the first and second ultrasound heads are different, they can detect different depths within the same detection area, resulting in different image contents. This allows for a more comprehensive examination of organs, aiding doctors in making diagnoses.

[0053] In some embodiments, the switching device includes a movable connecting seat, on which the first sound head and / or the second sound head are rotatably mounted. During movement of the connecting seat, it can drive the first sound head and / or the second sound head to switch positions between a detection position and a non-detection position.

[0054] In some embodiments, the connecting seat rotates about a fulcrum, and the first and second sound heads are respectively connected to both sides of the fulcrum, so that when the connecting seat swings about the fulcrum, the first and second sound heads move in opposite directions.

[0055] In some embodiments, the first and / or second sound heads are connected to the connecting seat via a universal bearing so that they can move relative to the connecting seat in multiple directions.

[0056] In some embodiments, the switching device includes a rotatable rotating member, with the first sound head and the second sound head disposed on the rotating member along the circumference of the rotating member. When the rotating member rotates, it can drive the first sound head and the second sound head to switch positions between a detection position and a non-detection position.

[0057] In some embodiments, the switching device further includes a transmission assembly comprising an active member and a driven member for inputting driving force, the driven member being connected to the rotating member, and the active member and the driven member forming a force-saving structure; the active member is driven by a motor or manually operated by an operator.

[0058] In some embodiments, the switching device includes a press-and-rebound mechanism, wherein the first sound head and the second sound head are respectively connected to a press-and-rebound mechanism, and the press-and-rebound mechanism is driven by a motor or manually operated by an operator.

[0059] In some embodiments, the switching device includes a driving component and a sound head connection switching mechanism. The sound head connection switching mechanism is capable of switching the connection relationship between the first sound head and the second sound head and the driving component. The driving component is used to drive the first sound head or the second sound head connected to it to switch positions between a detection position and a non-detection position.

[0060] In some embodiments, the switching device includes a rotatable component and a screw, the screw being connected to a corresponding first sound head and / or second sound head. Rotating the rotatable component can drive the screw to reciprocate along its axial direction, thereby causing the corresponding first sound head or second sound head to switch positions between a detection position and a non-detection position.

[0061] In some embodiments, the switching device includes a rotatable component with a spiral guide groove inside. The first sound head and / or the second sound head are mounted in the spiral guide groove via guide protrusions. Rotating the rotatable component can drive the corresponding first sound head or second sound head to switch between a detection position and a non-detection position.

[0062] In some embodiments, the switching device includes a telescopic connecting mechanism connected to the corresponding first sound head and / or second sound head. When the first sound head and / or second sound head is driven to move, the telescopic connecting mechanism can extend and retract, so that the corresponding first sound head or second sound head switches between a detection position and a non-detection position.

[0063] In some embodiments, the switching device includes a track on which the first sound head and / or the second sound head are mounted in a relatively movable manner. When the first sound head and / or the second sound head is driven to move, the first sound head and / or the second sound head can move relative to the track to switch positions between a detection position and a non-detection position.

[0064] In some embodiments, the track is tilted, and the first and second sound heads are located on opposite sides of the track and can extend in opposite directions to their respective detection positions.

[0065] In some embodiments, the switching device includes a telescopic connection mechanism, the probe housing has a telescopic portion, the first acoustic head and the second acoustic head are connected through the telescopic connection mechanism, and the first acoustic head, the second acoustic head and the telescopic connection mechanism are installed inside the probe housing; the telescopic portion and the telescopic connection mechanism form a linkage structure, when the telescopic portion is stretched and retracted, the telescopic connection mechanism is stretched and retracted synchronously, and drives the corresponding first acoustic head and / or second acoustic head to extend to the detection position and retract to the non-detection position.

[0066] In some embodiments, the first and second sound heads are arranged side by side facing the same direction, facing opposite directions, or at a certain angle.

[0067] For the purposes described above, some embodiments of this application provide an ultrasonic device, including:

[0068] The host computer has a main control unit and an instruction input component;

[0069] And medical ultrasound probes as described in any of the above;

[0070] The main control unit is communicatively connected to the probe control unit, and the command input component allows the operator to input ultrasound operation commands.

[0071] In some embodiments, the ultrasound operation commands include a first detection mode command and a second detection mode command;

[0072] When the main control unit receives the first detection mode instruction, the main control unit controls the probe control unit to send a first control signal to the first acoustic head or the first acoustic head unit to drive the first acoustic head or the first acoustic head unit to emit an ultrasonic signal for detection;

[0073] When the main control unit receives the second detection mode command, the main control unit controls the probe control unit to send a second control signal to the second acoustic head or the second acoustic head unit to drive the second acoustic head or the second acoustic head unit to emit ultrasonic signals for detection.

[0098] 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.

[0099] 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.

[0100] 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. Unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections (linkages).

[0101] In order to obtain a clearer picture of a certain area of ​​the object being tested (human or animal), some embodiments of this application provide a medical ultrasound probe. This medical ultrasound probe uses at least two sound heads with different center frequencies to probe different depths of the area, thereby obtaining more comprehensive test results, comprehensively screening organs, helping doctors to complete the diagnosis, improving the success rate of surgery, and bringing better prognosis to patients.

[0102] Please refer to Figure 1. This medical ultrasound probe is an intracavitary ultrasound probe capable of acquiring information about a specific area within the body cavity (such as the abdominal cavity or esophagus) of a subject (human or animal). It includes a probe control unit 1 (see Figure 6) and an acoustic probe segment 2 for insertion into the body cavity of the subject. The acoustic probe segment 2 can be inserted into the body cavity of the subject for detection. The probe control unit 1 is used to control the various acoustic probes on the acoustic probe segment 2.

[0103] In addition, in other embodiments, the medical ultrasound probe may also have other components as needed. For example, referring to Figure 1, in some embodiments, the medical ultrasound probe may also include a bending section 3 for bending the head segment 2, a handle assembly 4 for controlling the bending of the bending section 3 and the movement of the head segment 2, an insertion section 5 connecting the handle assembly 4 and the bending section 3, and a connecting cable 6, etc.

[0104] Referring to Figures 2 and 3, in some embodiments, the probe segment 2 has a probe base 21, a first probe 22 (at least one), and a second probe 23 (at least one). Both the first probe 22 and the second probe 23 are communicatively connected to the probe control unit 1. The first probe 22 and the second probe 23 have different center frequencies, enabling them to detect different depths. In other embodiments, the probe base 21 may also have a third or more probes. These probes can be mounted on the probe base 21 and have different center frequencies.

[0105] Referring to Figures 2 and 3, in some embodiments, the acoustic head segment 2 can rotate or move back and forth along its length under the control of an operator (who may be a doctor or another person). For example, in some embodiments, the rotation can be around the axis of the acoustic head base 21, and the length direction can be the axial direction of the acoustic head base 21. The first acoustic head 22 and the second acoustic head 23 are both located on the outer surface of the acoustic head base 21. The outer surface of the acoustic head base 21 refers to the circumferential outer wall surrounding the axis of the acoustic head base 21. Based on this, the operator can change the position of the acoustic head base 21 (e.g., by controlling the rotation or back and forth movement of the acoustic head base 21 via the handle assembly 4) to make the first acoustic head 22 and the second acoustic head 23 face the same detection area successively, thereby enabling the same detection area to be detected sequentially. Facing the same detection area means that the emitting surface of each acoustic head (i.e., the side of the acoustic head that emits and receives ultrasound signals) is set facing the same detection area. The same detection area is a certain area on the inner wall surface of the target body cavity. When the first acoustic probe 22 and the second acoustic probe 23 face the same direction within the body cavity, the surface areas of the inner cavity wall detected by the first acoustic probe 22 and the second acoustic probe 23 at least partially overlap, and this overlapping portion constitutes the same detection area. Since the center frequencies of the first acoustic probe 22 and the second acoustic probe 23 are different, when the first acoustic probe 22 and the second acoustic probe 23 face the same detection area, they can respectively detect different depths within the same detection area, thereby obtaining images of the tissue corresponding to different depths within the same detection area.

[0106] Among the transducers used in this application, those with a lower center frequency have better penetration, a wider imaging range, and can probe deeper tissues, such as clearly seeing deep lesions in the liver. Transducers with a higher center frequency, on the other hand, produce better images and can be used to detect superficial tissues, such as small lesions in the superficial areas of the liver, such as the liver capsule.

[0107] Specifically, referring to Figures 2 and 4, in some embodiments, by manipulating the position of the acoustic probe segment 2, the first acoustic probe 22 can be directed toward the detection area for the first image detection. Subsequently, referring to Figures 3 and 5, by manipulating the position of the acoustic probe segment 2, the second acoustic probe 23 can be directed toward the detection area for the second image detection. Although both image detections target the same detection area, the resulting images originate from tissues at different depths, and therefore the image content differs, allowing for a more comprehensive examination of organs and assisting doctors in making a diagnosis.

[0108] Referring to Figures 2-5, in some embodiments, the center frequency of the first acoustic probe 22 is 5-10 MHz, and the center frequency of the second acoustic probe 23 is 12-20 MHz. In this embodiment, the center frequency of the first acoustic probe 22 is lower than the center frequency of the second acoustic probe 23. That is, the first acoustic probe 22 is used for depth scanning, and the second acoustic probe 23 is used for shallow scanning. Of course, in other embodiments, the center frequency of the first acoustic probe 22 may be higher than the center frequency of the second acoustic probe 23.

[0109] Please refer to Figures 2-5. In some embodiments, the first sound head 22 may be a convex array sound head, and the second sound head 23 may be a linear array sound head. In other embodiments, the first sound head 22 and the second sound head 23 may both be linear array sound heads, or both may be convex array sound heads, or the first sound head 22 and the second sound head 23 may be other types of sound heads.

[0110] On the other hand, the first sound head 22 and the second sound head 23 can be arranged arbitrarily on the outer wall of the sound head base 21, as long as the operator can change the position of the sound head base 21 (such as by controlling the sound head base 21 to rotate or move back and forth through the handle assembly 4) so ​​that the first sound head 22 and the second sound head 23 face the same detection area one after the other, and thus can detect the same detection area one after the other.

[0111] Referring to Figures 2 and 3, in some more specific embodiments, the first sound head 22 and the second sound head 23 are located at different circumferential positions on the sound head base 21, for example, the positions of the first sound head 22 and the second sound head 23 are distributed around the axis of the sound head base 21. When the sound head base 21 is static, the emitting surfaces of the first sound head 22 and the second sound head 23 face different detection directions, so that when the sound head base 21 rotates, the emitting surfaces of the first sound head 22 and the second sound head 23 can face the same detection area sequentially.

[0112] In specific operation, please refer to Figure 2. In some embodiments, by manipulating the position of the acoustic head segment 2, the first acoustic head 22 can be oriented towards the detection area for the first image detection. Subsequently, referring to Figure 3, the acoustic head segment 2 can be rotated using the handle assembly 4 (and the acoustic head base 21 can be adjusted to move along its axial direction if necessary), thereby moving the first acoustic head 22 away from the detection area and the second acoustic head 23 towards the detection area for the second image detection. Although both image detections target the same detection area, the resulting images originate from tissues at different depths, and therefore the image content is different, allowing for a more comprehensive examination of organs and assisting doctors in making a diagnosis.

[0113] Furthermore, in some embodiments, at least a portion of the emitting surfaces of the first sound head 22 and the second sound head 23 lie on the same length segment along the length direction (i.e., axially) of the sound head base 21. That is, as shown in Figures 2 and 3, the emitting surfaces of the first sound head 22 and the second sound head 23 overlap at least partially in the length direction of the sound head base 21. Thus, when the sound head base 21 rotates to a set angle, the emitting surfaces of the first sound head 22 and the second sound head 23 can at least cover a portion of the same area, reducing the need for other adjustment actions by the operator.

[0114] In some embodiments, the emitting surfaces of the first sound head 22 and the second sound head 23 are located in the same length segment along the length direction (i.e., axial direction) of the sound head base 21; or, the length segment containing the emitting surface of the first sound head 22 is located within the length segment containing the emitting surface of the second sound head 23 along the length direction (i.e., axial direction) of the sound head base 21; or, the length segment containing the emitting surface of the second sound head 23 is located within the length segment containing the emitting surface of the first sound head 22 along the length direction (i.e., axial direction) of the sound head base 21. In these embodiments, when the sound head base 21 rotates to a set angle, the emitting surfaces of the first sound head 22 and the second sound head 23 can face the same area, without the need for additional back-and-forth adjustments to the position of the first sound head 22 or the second sound head 23 along the sound head axial direction.

[0115] Furthermore, in some embodiments, the angle difference between the first sound head 22 and the second sound head 23 can be arbitrarily set. Referring to Figures 2 and 3, in some embodiments, the emitting surfaces of the first sound head 22 and the second sound head 23 are circumferentially opposite to each other on the sound head base 21. That is, rotating the sound head base 21 by 180° will make the emitting surface of the second sound head 23 face the same direction as the emitting surface of the first sound head 22. When the emitting surfaces of the first sound head 22 and the second sound head 23 are circumferentially opposite to each other on the sound head base 21, the circumferential space of the sound head base 21 can be fully utilized, allowing for a greater distance between the first sound head 22 and the second sound head 23. This facilitates the installation of the first sound head 22 and the second sound head 23 on the sound head base 21 and reduces installation difficulty.

[0116] Please refer to Figures 4 and 5. In some embodiments, the first sound head 22 and the second sound head 23 are located at different positions along the length of the sound head base 21, so that when the sound head base 21 moves along its axial direction, the emitting surfaces of the first sound head 22 and the second sound head 23 can face the same detection area one after the other.

[0117] In specific operation, please refer to Figure 4. In some embodiments, by manipulating the position of the acoustic head segment 2, the first acoustic head 22 can be oriented towards the detection area for the first image detection. Subsequently, referring to Figure 5, the acoustic head segment 2 can be moved axially along its axis using the handle assembly 4 (and the acoustic head base 21 can be adjusted to rotate if necessary), thereby moving the first acoustic head 22 away from the detection area and causing the second acoustic head 23 to face the detection area for the second image detection. Although both image detections target the same detection area, the resulting images originate from tissues at different depths, thus the image content differs, allowing for a more comprehensive examination of organs and assisting doctors in making a diagnosis.

[0118] Furthermore, referring to Figures 4 and 5, in some embodiments, the emitting surface of the first sound head 22 and the emitting surface of the second sound head 23 are located on the same side of the sound head base 21. Thus, the operator only needs to move the sound head segment 2 along its axial direction to make the emitting surfaces of the first sound head 22 and the second sound head 23 face the same area, eliminating the need to adjust the rotation of the sound head base 21, simplifying the operation and making it easier to use.

[0119] In some embodiments, referring to Figures 4 and 5, the first sound head 22 is located in front of the second sound head 23 along the length of the sound head base 21. Alternatively, in other embodiments, the second sound head 23 may also be located in front of the first sound head 22. Here, "front and back" refers to the end of the sound head base 21 away from the handle assembly 4 being the front end, and the end closer to the handle assembly 4 being the rear end.

[0120] On the other hand, in some embodiments, in order to control the first acoustic probe 22 and the second acoustic probe 23, the medical ultrasound probe has a first detection mode and a second detection mode. In the first detection mode, the probe control unit 1 controls the first acoustic probe 22 to emit an ultrasound signal for detection. In the second detection mode, the probe control unit 1 controls the second acoustic probe 23 to emit an ultrasound signal for detection. By setting the first detection mode and the second detection mode, the operator can selectively activate the first detection mode or the second detection mode according to the position of the first acoustic probe 22 and the second acoustic probe 23 to prevent the first acoustic probe 22 or the second acoustic probe 23 from being activated ineffectively and wasting energy.

[0121] Furthermore, in some embodiments, in the first detection mode, the probe control unit 1 controls the second acoustic head 23 not to emit ultrasonic signals for detection; in the second detection mode, the probe control unit 1 controls the first acoustic head 22 to emit ultrasonic signals for detection.

[0122] Specifically, in some embodiments, when the first ultrasound head 22 is facing the detection area, the operator can activate the first detection mode. In this mode, the probe control unit 1 controls the first ultrasound head 22 to emit ultrasound signals for detection, and the resulting image is the image detected by the first ultrasound head 22. At this time, the second ultrasound head 23 is not activated, and there is no image feedback, thus preventing the image detected by the second ultrasound head 23 from affecting the doctor's judgment of the image detected by the first ultrasound head 22. Conversely, when the second ultrasound head 23 is facing the detection area, the operator can activate the second detection mode. In this mode, the probe control unit 1 controls the second ultrasound head 23 to emit ultrasound signals for detection, and the resulting image is the image detected by the second ultrasound head 23. In this mode, the first ultrasound head 22 is not activated, and there is no image feedback, thus preventing the image detected by the first ultrasound head 22 from affecting the doctor's judgment of the image detected by the second ultrasound head 23.

[0123] In other embodiments, this application also provides other medical ultrasound probes that can detect conditions at different depths of a detection area using sound waves with different center frequencies, thereby assisting doctors in making diagnoses, improving surgical success rates, and leading to better prognoses for patients. These medical ultrasound probes can be used for surface detection of the target body, as well as for intracavitary ultrasound probes as described in the foregoing embodiments or ultrasound probes in other scenarios.

[0124] Figures 7-21 illustrate various embodiments of medical ultrasound probes, each including a probe housing 24, at least one first acoustic head 22, at least one second acoustic head 23, and a switching device. Similarly, in addition to these components, the medical ultrasound probe may also include other components as needed.

[0125] The first acoustic probe 22 and the second acoustic probe 23 are mounted on the probe housing 24. This includes direct mounting of the first acoustic probe 22 and the second acoustic probe 23 to the probe housing 24, and indirect mounting via other structures, such as brackets. The switching device can switch the position of the first acoustic probe 22 and / or the second acoustic probe 23 between a detection position and a non-detection position. When the first acoustic probe 22 or the second acoustic probe 23 is in the detection position, it can be used for normal ultrasonic testing. When the first acoustic probe 22 or the second acoustic probe 23 is in the non-detection position, it is generally not used for ultrasonic testing.

[0126] The switching device mentioned here can drive the first sound head 22 and / or the second sound head 23 to switch positions between the detection position and the non-detection position. This includes the switching device being connected to both the first sound head 22 and the second sound head 23 at the same time, and one switching device can simultaneously control the first sound head 22 and the second sound head 23 to switch positions between the detection position and the non-detection position. It also includes a switching device being connected to only the first sound head 22 or the second sound head 23, and only driving the first sound head 22 or the second sound head 23 to switch positions between the detection position and the non-detection position. In this case, the first sound head 22 and the second sound head 23 can each be equipped with a corresponding switching device for control.

[0127] In the medical ultrasound probes shown in these embodiments, there are both a first acoustic probe 22 and a second acoustic probe 23. The operator can change the position of the first acoustic probe 22 and the second acoustic probe 23 by using a switching device, so that the first acoustic probe 22 and the second acoustic probe 23 face the same detection area one after the other. Since the center frequencies of the first acoustic probe 22 and the second acoustic probe 23 are different, the first acoustic probe 22 and the second acoustic probe 23 can detect different depths of the same detection area.

[0128] In some embodiments, the first sound head 22 and the second sound head 23 are arranged side by side facing the same direction, facing opposite directions, or at a certain angle.

[0129] The following examples illustrate the design of the switching device.

[0130] Referring to Figure 7, in some embodiments, the switching device includes a movable connector 251. The first sound head 22 and / or the second sound head 23 are rotatably mounted on the connector 251. During movement of the connector 251, it can drive the first sound head 22 and / or the second sound head 23 to switch between a detection position and a non-detection position.

[0131] Specifically, in Figure 7, taking the first sound head 22 as an example (the same applies to the second sound head 23), the first sound head 22 is in the non-detection position. When the left end of the connecting seat 251 moves upward, it can drive the first sound head 22 to move upward, thereby moving to the detection position. This detection position can be when the first sound head 22 (or the second sound head 23) is flush with or extends beyond the end face of the probe housing 24. Of course, in some embodiments, the detection position can also be when the first sound head 22 (or the second sound head 23) is lower than the end face of the probe housing 24.

[0132] In this embodiment, since the first acoustic head 22 (or the second acoustic head 23) can rotate relative to the connecting seat 251, the position of the first acoustic head 22 (or the second acoustic head 23) relative to the connecting seat 251 can also be adjusted. In particular, in some embodiments, the movement of the connecting seat 251 is an oscillation around a fulcrum. In this case, if the rotation axis of the first acoustic head 22 (or the second acoustic head 23) relative to the connecting seat 251 is parallel to the rotation axis of the connecting seat 251 about the fulcrum (e.g., perpendicular to the plane of the drawing), the operator can adjust the emitting surface angle of the first acoustic head 22 (or the second acoustic head 23) by rotating it. For example, it can be adjusted to a position parallel to the end face of the probe housing 24 or to a more closely fit angle to the patient's skin for better ultrasound detection.

[0133] In Figure 7, the connecting seat 251 rotates about a pivot point, which can be formed by a shaft or other structure (such as the universal bearing 2522 shown later). This axis of rotation is at least parallel to the axis of rotation of the first sound head 22 (or the second sound head 23). Of course, in other embodiments, the connecting seat 251 may also be designed for translation or other modes of movement.

[0134] Furthermore, in some embodiments, referring to Figure 7, the first sound head 22 and the second sound head 23 share a connecting seat 251, which is connected to both sides of the fulcrum, forming a seesaw-like structure. This ensures that when the connecting seat 251 swings around the fulcrum, the first sound head 22 and the second sound head 23 move in opposite directions. In this case, if the first sound head 22 is driven towards the detection position, the second sound head 23 will move towards the non-detection position, and vice versa.

[0135] In addition, in other embodiments, the first sound head 22 and the second sound head 23 may also be provided with corresponding connecting seats 251, and their movement is driven by the movement of the corresponding connecting seats 251, instead of sharing a single connecting seat 251.

[0136] To allow the first sound head 22 and / or the second sound head 23 to have more degrees of freedom for adjustment in multiple directions, please continue to refer to Figure 7. In some embodiments, the first sound head 22 and / or the second sound head 23 can be connected to the connecting seat 251 via a universal bearing 2521, so that it can move relative to the connecting seat 251 in multiple directions, thereby adjusting the angle of the emitting surface of the first sound head 22 and / or the second sound head 23. The universal bearing 2521 may include, but is not limited to, a universal ball bearing or other structures capable of rotation in any direction. In Figure 7, both the first sound head 22 and the second sound head 23 are provided with universal bearings 2521, and the connecting seat 251 also has a universal bearing 2522. The universal bearings 2521 and 2522 can be connected to each other via a connecting shaft 2523.

[0137] In addition, in some embodiments, the connector 251 may be directly or indirectly mounted on the probe housing 24 or other components. To provide more angle adjustment variations, the connector 251 may also be directly or indirectly mounted on the probe housing 24 or other components (base 2524 connected to the probe housing 24) via a universal bearing 2522, which can serve as a fulcrum for the connector 251.

[0138] Referring to Figure 7, when the first acoustic probe 22 and the second acoustic probe 23 move relative to the probe housing 24, a flexible material 253 can be provided between the first acoustic probe 22 and the second acoustic probe 23 and the probe housing 24 to improve sealing. This flexible material 253 is elastic and can be made of materials such as silicone. This flexible material 253 achieves both sealing and reduces wear on the first acoustic probe 22 and the second acoustic probe 23. The flexible material 253 can be provided on the first acoustic probe 22 and the second acoustic probe 23, or on the probe housing 24.

[0139] In the embodiment shown in Figure 7, the connector 251 can be manually driven by the operator or electrically driven by a motor or other power source.

[0140] Furthermore, in the embodiment shown in FIG7, the first acoustic probe 22 and the second acoustic probe 23 may be arranged side by side, which can form a compact structure and reduce the overall size of the probe.

[0141] Referring to Figures 8-10, in some embodiments, the switching device includes a rotatable rotating member 254. A first acoustic probe 22 and a second acoustic probe 23 are disposed circumferentially on the rotating member 254. When the rotating member 254 rotates, it can drive the first acoustic probe 22 and the second acoustic probe 23 to switch positions between a detection position and a non-detection position. As shown in Figures 8 and 10, at this time, the first acoustic probe 22 is in the detection position, and the second acoustic probe 23 is in the non-detection position. By rotating the rotating member 254 counterclockwise, the first acoustic probe 22 can move to the non-detection position, and the second acoustic probe 23 can move to the detection position. If it is necessary to return the first acoustic probe 22 to the detection position, the rotating member 254 can be rotated clockwise. The detection position can be when the first acoustic probe 22 (or the second acoustic probe 23) is flush with or extends beyond the end face of the probe housing 24. Of course, in some embodiments, the detection position can also be when the first acoustic probe 22 (or the second acoustic probe 23) is lower than the end face of the probe housing 24.

[0142] The rotating component 254 can be a disc, a wheel, or other shapes and structures. The rotating component 254 can be manually driven by an operator or electrically driven by a motor or other power source.

[0143] Further, referring to Figures 8 and 9, in some embodiments, the switching device further includes a transmission assembly 255, which includes an active member 2551 and a driven member 2552 for inputting driving force. The active member 2551 and the driven member 2552 form a force-saving structure. The active member 2551 is driven by a motor 256 or manually operated by an operator. For example, the active member 2551 may be provided with a handle for operating and rotating the active member 2551. This transmission assembly 255 facilitates the operator or motor to drive the switching of the first sound head 22 and the second sound head 23 with less driving force.

[0144] In Figures 8 and 9, the driving element 2551 and the driven element 2552 are a gear transmission assembly, wherein the driving element 2551 is a large gear and the driven element 2552 is a small gear. In other embodiments, the driving element 2551 and the driven element 2552 may also be a synchronous belt or synchronous chain structure.

[0145] Referring to Figure 10, in some embodiments of this application, a modified scheme is also provided. The transmission assembly 255 can be designed as a Geneva wheel transmission mechanism 257. Compared to the gear transmission assembly shown in Figure 8, this Geneva wheel transmission mechanism 257 does not require back-and-forth rotation; it only rotates in the same direction to complete the movement of the first sound head 22 and the second sound head 23 towards the detection position. The Geneva wheel transmission mechanism 257 is provided with levers 2571 and 2571 so that the operator can manually control it. Of course, in other embodiments, the Geneva wheel transmission mechanism 257 can also be replaced with an incomplete gear transmission mechanism.

[0146] Furthermore, in the embodiments shown in Figures 8-10, the first sound head 22 and the second sound head 23 may be arranged in different directions, but are not limited to.

[0147] Referring to Figure 11, in some embodiments, the switching device includes a press-and-rebound mechanism 258. The first sound head 22 and the second sound head 23 are each connected to a press-and-rebound mechanism 258. The press-and-rebound mechanism 258 operates on the same principle as a ballpoint pen press mechanism; when pressed, it pushes the corresponding first sound head 22 or second sound head 23 out, and the press-and-rebound mechanism 258 self-locks. When pressed again, the press-and-rebound mechanism 258 automatically rebounds, the first sound head 22 retracts, and returns to the non-detection position. The press-and-rebound mechanism 258 is driven by a motor or manually operated by the operator. The detection position can be flush with or extend beyond the end face of the probe housing 24; however, in some embodiments, the detection position can also be where the first sound head 22 (or second sound head 23) is below the end face of the probe housing 24.

[0148] Furthermore, in the embodiment shown in FIG11, the first acoustic probe 22 and the second acoustic probe 23 may be arranged side by side, which can form a compact structure and reduce the overall volume of the probe.

[0149] Referring to Figure 12, in some embodiments, the press-and-rebound mechanism 258 may include a spring 2581, a spring-limiting sleeve 2582, a guide sleeve 2583, and a push rod 2584 (which may also be integrated with a button). The push rod 2584 is inserted into the guide sleeve 2583 and abuts against the spring-limiting sleeve 2582. The inner wall of the guide sleeve 2583 has a limiting guide groove 2583a to guide the movement of the push rod 2584. The guide sleeve 2583 may be integrated into the probe housing 24 or be a separate component. The spring-limiting sleeve 2582 is connected to the corresponding first sound head 22 or second sound head 23 via a connecting shaft 259. When the push rod 2584 is pressed, the spring-limiting sleeve 2582 and the corresponding first sound head 22 or second sound head 23 can be pushed out, and the press-and-rebound mechanism 258 achieves self-locking. When the press-rebound mechanism 258 is pressed again, it achieves contact self-locking. Under the action of the spring 2581, the press-rebound mechanism 258 automatically rebounds, and the first sound head 22 or the second sound head 23 retracts back to the non-detection position. The detection position can be flush with or beyond the end face of the probe housing 24. Of course, in some embodiments, the detection position can also be that the first sound head 22 (or the second sound head 23) is lower than the end face of the probe housing 24.

[0150] Referring to Figures 13 and 14, in some embodiments, the switching device includes a drive assembly 259 and a probe connection switching mechanism 260. The probe connection switching mechanism 260 can switch the connection relationship between the first probe 22 and the second probe 23 and the drive assembly 259, for example, connecting the first probe 22 to the drive assembly 259, or connecting the second probe 23 to the drive assembly 259. The drive assembly 259 is used to drive the first probe 22 or the second probe 23 connected to it to switch positions between a detection position and a non-detection position. In this embodiment, the detection position can be flush with or extending beyond the end face of the probe housing 24; however, in some embodiments, the detection position can also be where the first probe 22 (or the second probe 23) is below the end face of the probe housing 24. The drive assembly 259 can be a structure driven by a motor or other power source.

[0151] Furthermore, in the embodiment shown in FIG13, the first acoustic probe 22 and the second acoustic probe 23 may be arranged side by side, which can form a compact structure and reduce the overall volume of the probe.

[0152] More specifically, referring to Figures 13 and 14, in some embodiments, the first sound head 22 and the second sound head 23 are respectively provided with a connecting component 261, which includes a rack 2611. The first sound head 22 and the second sound head 23 are fixed to the corresponding rack 2611. The driving component 259 includes a motor 2591 and a driving gear set, which has a first driving gear 2592 for driving the first sound head 22 to move and a second driving gear 2593 for driving the second sound head 23 to move. The sound head connection switching mechanism 260 includes a first intermediate gear 2601 and a second intermediate gear 2602. The sound head connection switching mechanism 260 can be moved such that the first intermediate gear 2601 connects the first driving gear 2592 to the rack 2611 corresponding to the first sound head 22, or the second intermediate gear 2602 connects the second driving gear 2593 to the rack 2611 corresponding to the second sound head 23. As shown in Figure 13, at this time, the first intermediate gear 2601 simultaneously meshes with the first drive gear 2592 and the rack 2611 corresponding to the first sound head 22. The power output by the motor 2591 can then be transmitted to the rack 2611 corresponding to the first sound head 22, driving the rack 2611 to move, thereby causing the first sound head 22 to extend and retract. Similarly, when the second intermediate gear 2602 connects the second drive gear 2593 to the rack 2611 corresponding to the second sound head 23, the power output by the motor 2591 can be transmitted to the rack 2611 corresponding to the second sound head 23, driving the rack 2611 to move, thereby causing the second sound head 23 to extend and retract.

[0153] Please refer to Figure 14. In some embodiments, in order to make the movement of the first sound head 22 and the second sound head 23 smoother, the rack 2611 is provided with a guide rail 2612, and the rack 2611 is slidably mounted on the guide rail 2612.

[0154] Referring to Figure 13, in some embodiments, the sound head connection switching mechanism 260 further includes an electromagnetic module 2603, a connecting shaft 2604 with a permanent magnet base, and a guide rail 2603. When energized, the electromagnetic module 2603 drives the connecting shaft 2604 to move axially. The first intermediate gear 2601 and the second intermediate gear 2602 are mounted on the connecting shaft 2604, thereby changing their positions. The guide rail 2603 guides the reciprocating motion of the connecting shaft 2604. Of course, the sound head connection switching mechanism 260 can also drive the first intermediate gear 2601 and the second intermediate gear 2602 to reciprocate in other ways, such as using a linear motor, a cylinder, or a hydraulic cylinder.

[0155] Referring to Figure 15, in some embodiments, the switching device includes a rotatable rotating member 262 and a screw 263. The screw 263 is connected to the corresponding first sound head 22 and / or second sound head 23, for example, via a support base 264. Rotating the rotating member 262 drives the screw 263 to reciprocate along its axial direction. For example, the rotating member 262 and the screw 263 form a lead screw and nut pair to switch the corresponding first sound head 22 or second sound head 23 between a detection position and a non-detection position. The detection position can be flush with or beyond the end face of the probe housing 24. Of course, in some embodiments, the detection position can also be where the first sound head 22 (or second sound head 23) is below the end face of the probe housing 24. The driving assembly 259 can be a structure driven by a motor or other power source.

[0156] In Figure 15, the first sound head 22 and the second sound head 23 can each be equipped with their own corresponding screw 263 and rotating member 262, meaning that the extension and retraction of the first sound head 22 and the second sound head 23 can be controlled independently. Furthermore, in other embodiments, the first sound head 22 and the second sound head 23 can also share the same set of screw 263 and rotating member 262. For example, the screw 263 can be connected to both the first sound head 22 and the second sound head 23 simultaneously, and the screw 263 can be connected to the same rotating member 262. By rotating the same rotating member 262 in different directions, the movement of the first sound head 22 and the second sound head 23 can be controlled.

[0157] Furthermore, in the embodiment shown in FIG11, the first acoustic head 22 and the second acoustic head 23 may be arranged in opposite directions, but not limited to, which can form a compact structure and reduce the overall volume of the probe.

[0158] Referring to Figures 16 and 17, some embodiments also provide another rotary drive method. This switching device includes a rotatably mounted rotating member 262, which may be part of or rotatably mounted on the probe housing 24. The rotating member 262 has a helical guide groove 2621 inside, and the first acoustic probe 22 and / or the second acoustic probe 23 are mounted within the helical guide groove 2621 via a guide protrusion 2641. The guide protrusion 2641 is provided on a support seat 264, but may also be directly provided on the first acoustic probe 22 or the second acoustic probe 23. The first acoustic probe 22 and the second acoustic probe 23 are mounted in the probe housing 24 in an axially movable manner, for example, mounted on a support shaft 265. Similar to a lipstick's rotating opening mechanism, when the rotating component 262 is rotated, the first sound head 22 and the second sound head 23 can move axially along the support shaft 265 in cooperation with the guide protrusion 2641 and the spiral guide groove 2621, thereby driving the corresponding first sound head 22 or second sound head 23 to switch between a detection position and a non-detection position. The detection position can be flush with or extend beyond the end face of the probe housing 24; in some embodiments, the detection position can also be where the first sound head 22 (or second sound head 23) is below the end face of the probe housing 24. The driving assembly 259 can be a structure driven by a motor or other power source.

[0159] In the embodiment shown in Figure 16, the first sound head 22 and the second sound head 23 may be arranged in opposite directions, which can form a compact structure and reduce the overall volume of the probe.

[0160] Referring to Figure 18, in some embodiments, the switching device includes a telescopic connecting mechanism 266. This telescopic connecting mechanism 266 is a structure capable of extending and retracting under external force, such as the quadrilateral linkage mechanism shown in Figure 18. Alternatively, it can be a link (as shown in Figures 20 and 21) or a chain structure. The telescopic connecting mechanism 266 is connected to the corresponding first sound head 22 and / or second sound head 23. When the first sound head 22 and / or second sound head 23 are driven to move, the telescopic connecting mechanism 266 extends and retracts, allowing the corresponding first sound head 22 or second sound head 23 to switch positions between a detection position and a non-detection position. The detection position can be flush with or extend beyond the end face of the probe housing 24. Of course, in some embodiments, the detection position can also be where the first sound head 22 (or second sound head 23) is lower than the end face of the probe housing 24.

[0161] The first sound head 22 and the second sound head 23 may also be directly or indirectly equipped with levers 2571 and 2571, so that the operator can manually control the movement of the first sound head 22 and the second sound head 23. Of course, the extension and retraction of the telescopic connecting mechanism 266 can also be performed by a motor or other power source.

[0162] In the embodiment shown in Figure 18, the first sound head 22 and the second sound head 23 may be arranged in opposite directions, which can form a compact structure and reduce the overall volume of the probe.

[0163] Please refer to Figure 19. In some embodiments, the switching device includes a track 267. The first sound head 22 and / or the second sound head 23 are mounted on the track 267 in a relatively movable manner. When the first sound head 22 and / or the second sound head 23 are driven to move by an operator's external force or a motor, the first sound head 22 and / or the second sound head 23 can move relative to the track 267 to switch positions between a detection position and a non-detection position.

[0164] Further, referring to Figure 19, in some embodiments, the track 267 is inclined, and the first sound head 22 and the second sound head 23 are respectively located on both sides of the track 267 and can extend to their respective detection positions in opposite directions.

[0165] More specifically, referring to Figure 19, the track 267 is a rack with teeth on both sides. The first sound head 22 and the second sound head 23 are each equipped with a rotatable gear 268. When the first sound head 22 and / or the second sound head 23 are driven by external force from the operator or by a motor, they can move on the track 267 via the gears 268. Of course, in other embodiments, the rack serving as the track 267 can be replaced with a slide rail or other structures.

[0166] In Figure 19, the first sound head 22 and / or the second sound head 23 are provided with a lever 2571, which protrudes from the limiting hole 241 on the probe housing 24, so that the operator can directly control the movement of the first sound head 22 and / or the second sound head 23 by pushing the lever 2571. Of course, the movement of the first sound head 22 and the second sound head 23 can also be performed by a motor or other power source.

[0167] Referring to Figures 20 and 21, in some embodiments, the switching device includes a telescopic connecting mechanism 266. The probe housing 24 has a telescopic portion 242. The first acoustic probe 22 and the second acoustic probe 23 are connected via the telescopic connecting mechanism 266, and the first acoustic probe 22, the second acoustic probe 23, and the telescopic connecting mechanism 266 are installed inside the probe housing 24. The telescopic portion 242 and the telescopic connecting mechanism 266 form a linkage structure. When the telescopic portion 242 is stretched and retracted, the telescopic connecting mechanism 266 is stretched and retracted synchronously, driving the corresponding first acoustic probe 22 and / or second acoustic probe 23 to extend to the detection position and retract to the non-detection position. The stretching and retraction of the telescopic portion 242 can be manually operated by an operator or driven by a motor or other power source.

[0168] The telescopic section 242 can be a folding structure to facilitate extension and retraction. Of course, it can also be implemented using other telescopic structures in the prior art.

[0169] In the embodiments shown in Figures 20 and 21, the first acoustic probe 22 and the second acoustic probe 23 may be arranged in opposite directions, which can form a compact structure and reduce the overall volume of the probe.

[0170] The above embodiments illustrate the structures of various switching devices to achieve the purposeful switching of the first sound head 22 or the second sound head 23 for detection. The first sound head 22 and the second sound head 23 also employ the structures shown in any of the foregoing embodiments.

[0171] In addition, in order to address the problem that existing medical ultrasound probes have a limited range of detection depths for the target area, some embodiments of this application also provide a solution from another perspective.

[0172] Referring to Figures 22-27, in some embodiments, a medical ultrasound probe head module 100 is also provided, which includes at least one first head unit 110 and at least one second head unit 120. Both the first head unit 110 and the second head unit 120 can independently perform ultrasound examinations.

[0173] The first sound head unit 110 includes a first backing layer 111, a first positive lead-out circuit layer 112 (such as a flexible circuit board), a first array element layer 113, a first negative lead-out circuit layer 114 (such as a flexible circuit board or copper foil), and a first matching layer 115 arranged sequentially. The first backing layer 111, the first positive lead-out circuit layer 112, the first array element layer 113, the first negative lead-out circuit layer 114, and the first matching layer 115 are stacked. The first negative lead-out circuit layer 114 is electrically connected to the negative terminal of the first array element layer 113, and the first positive lead-out circuit layer 112 is electrically connected to the positive terminal of the first array element layer 113.

[0174] The second sound head unit 120 includes a second backing layer 121, a second positive lead-out circuit layer 122 (such as a flexible circuit board), a second array element layer 123, a second negative lead-out circuit layer 124 (such as a flexible circuit board or copper foil), and a second matching layer 125 arranged sequentially. The second backing layer 121, the second positive lead-out circuit layer 122, the second array element layer 123, the second negative lead-out circuit layer 124, and the second matching layer 125 are stacked. The second negative lead-out circuit layer 124 is electrically connected to the negative terminal of the second array element layer 123, and the second positive lead-out circuit layer 122 is electrically connected to the positive terminal of the second array element layer 123.

[0175] The first element layer 113 and the second element layer 123 have different applicable center frequencies. For example, the first element layer 113 and the second element layer 123 have different thicknesses, allowing the first acoustic head unit 110 and the second acoustic head unit 120 to detect different depths of the same detection area. The acoustic head unit with a lower center frequency has better penetration, a larger imaging range, and can detect deeper tissues, such as deep lesions. Conversely, the acoustic head unit with a higher center frequency produces better images and can be used to detect superficial tissues, such as small lesions in superficial areas.

[0176] For example, in some embodiments, the center frequency of the first acoustic module 110 is 5-10 MHz, and the center frequency of the second acoustic module 120 is 12-20 MHz. In this embodiment, the center frequency of the first acoustic module 110 is lower than the center frequency of the second acoustic module 120. That is, the first acoustic module 110 is used for depth scanning, and the second acoustic module 120 is used for shallow scanning. Of course, in other embodiments, the center frequency of the first acoustic module 110 may also be higher than the center frequency of the second acoustic module 120. For example, the center frequency of the first acoustic module 110 is 12-20 MHz, and the center frequency of the second acoustic module 120 is 5-10 MHz.

[0177] In addition, in some embodiments, the first array element layer 113 may be a convex array element and the second array element layer 123 may be a linear array element; or, the second array element layer 123 may be a convex array element and the first array element layer 113 may be a linear array element.

[0178] By manipulating the position of the ultrasound probe, the first ultrasound head unit 110 of the ultrasound head module 100 can be oriented towards the detection area for the first image detection. Subsequently, by changing the position of the ultrasound probe, the second ultrasound head unit 120 of the ultrasound head module 100 can be oriented towards the detection area for a second image detection. Although both image detections target the same detection area, the resulting images originate from tissues at different depths, thus producing different image content. This allows for a more comprehensive examination of organs, aiding doctors in making a diagnosis.

[0179] Unlike other embodiments that simultaneously provide at least two ultrasound probes, this application integrates two ultrasound probe units in a single ultrasound probe module 100. This allows for the detection of tissues at different depths within the detection area and also makes the ultrasound probe more compact.

[0180] Further, referring to Figures 22-27, in some embodiments, in order to make the entire head module 100 structure more compact and reduce the volume of the head module 100, the first head unit 110 and the second head unit 120 are arranged side by side, and the first backing layer 111 and the second backing layer 121 are an integral structure.

[0181] Further, referring to Figures 22-27, in some embodiments, there are at least two first acoustic head units 110, wherein the two first acoustic head units 110 are symmetrically arranged on both sides of at least one second acoustic head unit 120, so that in a static state, the detection area of ​​the second acoustic head unit 120 located between the two first acoustic head units 110 can at least partially overlap with the detection areas corresponding to the two first acoustic head units 110. For example, the focal points of the first acoustic head unit 110 and the focal points of the second acoustic head unit 120 are approximately converged on the same axis. When the operator uses an ultrasonic probe with this acoustic head module 100 for detection, there is no need to frequently change the position of the ultrasonic probe. The operator only needs to switch the control signal to make the first acoustic head unit 110 and the second acoustic head unit 120 detect the target detection area.

[0182] To simplify the structure, please refer to Figures 22, 23, and 25. In some embodiments, the first positive lead-out circuit layer 112 of at least one first head unit 110 and the second positive lead-out circuit layer 122 of at least one second head unit 120 are integrally formed; and / or, the first negative lead-out circuit layer 114 of at least one first head unit 110 and the second negative lead-out circuit layer 124 of at least one second head unit 120 are integrally formed. This integral structure not only simplifies the structure of the first head unit 110 and the second head unit 120, but also reduces the number of lead-out circuit layers, and simplifies the assembly of the first head unit 110 and the second head unit 120.

[0183] In some embodiments, such as those shown in Figures 22, 23, and 25, the thicknesses of the first array element layer 113 and the second array element layer 123 are different. In this case, in order to make the first positive electrode lead-out circuit layer 112 and the second positive electrode lead-out circuit layer 122 an integral structure, and / or to make the first negative electrode lead-out circuit layer 114 and the second negative electrode lead-out circuit layer 124 an integral structure, a position compensation member 116 is provided on the positive and / or negative electrode surfaces of the first array element layer 113 of at least one first sound head unit 110. The position compensation member 116 is made of conductive material so that the positive and / or negative electrode surfaces of the first sound head unit 110 can be flush with the positive and / or negative electrode surfaces of the second array element layer 123 of at least one second sound head unit 120. And / or, at least one second sound head unit 120 has a position compensation member 126 on the positive and / or negative electrode surface of the second element layer 123, the position compensation member 126 being a conductive material, so that the positive and / or negative electrode surface of the second sound head unit 120 can be flush with the positive and / or negative electrode surface of the first element layer 113 of at least one first sound head unit 110.

[0184] Please refer to Figures 24, 26, and 27. Even if the first positive lead-out circuit layer 112 and the second positive lead-out circuit layer 122 are not integrated, and the first negative lead-out circuit layer 114 and the second negative lead-out circuit layer 124 are not integrated, position compensation components 116 and 126 can be used to make the positive and / or negative surfaces of the first sound head unit 110 flush with the positive and / or negative surfaces of the second element layer 123 of at least one second sound head unit 120, and / or make the positive and / or negative surfaces of the second sound head unit 120 flush with the positive and / or negative surfaces of the first element layer 113 of at least one first sound head unit 110, so as to form a more neat structure and make it easier to cooperate with other components.

[0185] Furthermore, referring to Figures 22-27, in some embodiments, at least one of the first negative electrode lead-out circuit layer 114, the first array element layer 113, the first positive electrode lead-out circuit layer 112, and the first matching layer 115 of the first sound head unit 110 is an independent structure. And / or, at least one of the second negative electrode lead-out circuit layer 124, the second array element layer 123, the second positive electrode lead-out circuit layer 122, and the second matching layer 125 of the second sound head unit 120 is an independent structure.

[0186] Further, referring to FIG34, in some embodiments, the thicknesses of the first element layer 113 and the second element layer 123 are different, wherein the first backing layer 111 of at least one first sound head unit 110 protrudes relative to the second backing layer 121 of at least one second sound head unit 120, or the second backing layer 121 of at least one second sound head unit 120 protrudes relative to the first backing layer 111 of at least one first sound head unit 110, so that the positive electrode surface of the first element layer 113 of the first sound head unit 110 is flush with the positive electrode surface of the second element layer 123 of the second sound head unit 120.

[0187] To address the issue of limited detection depth in existing medical ultrasound probes for the target area, other embodiments also provide additional head modules 100.

[0188] Referring to Figures 28-32, in some embodiments, the sound head module 100 includes at least one first sound head unit 110 and at least one second sound head unit 120. The first sound head unit 110 includes a first array element layer 113, and the second sound head unit 120 includes a second array element layer 123.

[0189] The first acoustic probe unit 110 and the second acoustic probe unit 120 are capable of independent ultrasonic detection, and the first array element layer 113 and the second array element layer 123 have different applicable center frequencies (refer to the description of different center frequencies above). The first acoustic probe unit 110 and the second acoustic probe unit 120 are independent of each other and arranged side by side. The first acoustic probe unit 110 and the second acoustic probe unit 120 can be connected or fixed in relative position by different methods such as bonding, welding, and fixing.

[0190] In these embodiments, the first sound head unit 110 and the second sound head unit 120 are independent of each other and can be manufactured separately, which simplifies manufacturing. Furthermore, the side-by-side arrangement of the first sound head unit 110 and the second sound head unit 120 improves the structural compactness of the entire sound head module 100, thus reducing the overall size of the sound head module 100.

[0191] Referring to Figure 28, in some embodiments, there are at least two first acoustic head units 110, wherein the two first acoustic head units 110 are symmetrically arranged on both sides of at least one second acoustic head unit 120, so that in a static state, the detection area of ​​the second acoustic head unit 120 located between the two first acoustic head units 110 can at least partially overlap with the detection areas corresponding to the two first acoustic head units 110. For example, the focal points of the first acoustic head unit 110 and the focal points of the second acoustic head unit 120 are approximately converged on the same axis. When the operator uses an ultrasonic probe with this acoustic head module 100 for detection, there is no need to frequently change the position of the ultrasonic probe. The operator only needs to switch the control signal to make the first acoustic head unit 110 and the second acoustic head unit 120 detect the target detection area.

[0192] Please refer to Figures 31 and 32. In some embodiments, the thicknesses of the first array element layer 113 and the second array element layer 123 are different, and the emitting surfaces of the first sound head unit 110 and the second sound head unit 120 are flush. Please refer to Figure 28. In some embodiments, the emitting surfaces of the first sound head unit 110 and the second sound head unit 120 may also have a height difference.

[0193] Please continue referring to Figures 28-32. In some embodiments, the first positive lead-out circuit layer 112 of the first sound head unit 110 located on both sides can be led out from the outside of the first sound head unit 110 away from the second sound head unit 120, while the second positive lead-out circuit layer 122 of the second sound head unit 120 can extend from the middle of the two first sound head units 110. The first negative lead-out circuit layer 114 of the first sound head unit 110 and the second negative lead-out circuit layer 124 of the second sound head unit 120 are led out from the side of the first sound head unit 110 and the second sound head unit 120 through the flexible circuit board 131 (see Figure 32). This structure is more compact and is conducive to the miniaturization of the overall structure.

[0194] Furthermore, some embodiments of this application also provide a medical ultrasound probe, which includes a probe housing 24 and a head module 100 as shown in any of the above embodiments, the head module 100 being mounted on the probe housing 24.

[0195] Furthermore, some embodiments of this application provide an ultrasound device for intracavitary detection, which includes a main unit and a medical ultrasound probe as described above. The main unit has a main control unit and a command input component. The command input component may employ, but is not limited to, physical buttons, virtual buttons, a voice control unit, a posture capture unit, or other structures capable of command input. The main control unit is communicatively connected to the probe control unit 1, and the command input component allows the operator to input ultrasound operation commands.

[0196] Furthermore, in some embodiments, the ultrasound operation command may include a first detection mode command and a second detection mode command:

[0197] When the main control unit receives the first detection mode command, the main control unit controls the probe control unit 1 to send a first control signal to the first acoustic head 22 or the first acoustic head unit 110 to drive the first acoustic head 22 or the second acoustic head unit 120 to emit ultrasonic signals for detection.

[0198] When the main control unit receives the second detection mode command, the main control unit controls the probe control unit 1 to send a second control signal to the second acoustic head 23 or the second acoustic head unit 120 to drive the second acoustic head 23 or the second acoustic head unit 120 to emit ultrasonic signals for detection.

[0199] 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.
