Description

Technical Field

[0001] This application relates to the field of medical devices, and particularly to a structure of a laparoscopic ultrasound probe for intracavitary detection. Background Art

[0002] An ultrasound probe is an important component of an ultrasound device (such as an ultrasound diagnostic imaging device). Its working principle is to use the piezoelectric effect to convert the excitation electrical pulse signal of the ultrasound whole machine into an ultrasonic wave signal and enter the patient's body, and then convert the ultrasonic echo signal reflected by the tissue into an electrical signal, so as to realize the detection of the tissue.

[0003] Among them, the laparoscopic ultrasound probe is a type of ultrasound probe, such as but not limited to a conventional transesophageal probe. The laparoscopic ultrasound probe is applied in the body cavity of a human or an animal to obtain intracavitary images. The laparoscopic ultrasound probe usually has an insertion component inserted into the body cavity of a human or an animal. A sound head is provided at the front end of the insertion component. The sound head can emit and receive ultrasonic waves, so as to detect a target detection area in the body cavity and form an image.

[0004] However, the detection depth of the existing laparoscopic ultrasound probe for the target detection area is relatively single, and it is difficult to obtain richer information for doctors to refer to. Summary of the Invention

[0005] This application provides a laparoscopic ultrasound probe and an ultrasound device for communicatively connecting with a laparoscope, which can detect different depths of the same detection area.

[0006] Based on the above purpose, in some embodiments of this application, a laparoscopic ultrasound probe is provided, including a sound head section, a bending section connected to the sound head section, an insertion section connected to the bending section, a handle assembly connected to the insertion section, and a probe control unit. The handle assembly includes a worm and gear transmission mechanism and a control component. The control component includes a control member for an operator to input an operation instruction. The control member forms a linkage structure with the worm of the worm and gear transmission mechanism to drive the worm to rotate, or the control member drives the worm of the worm and gear transmission mechanism to rotate by an electric control method; the turbine of the worm and gear transmission mechanism is connected to the insertion section to drive the insertion section, the bending section, and the sound head section to rotate as a whole;

[0007] The first sound head and the second sound head are arranged on different sides of the sound head base, so that when the sound head base rotates around its axis, the emission surfaces of the first sound head and the second sound head can successively face the same detection area; the center frequencies of the first sound head and the second sound head are different, so that the first sound head and the second sound head can detect different depths;

[0008] Both the first acoustic head and the second acoustic head are communicatively connected to the probe control unit; the laparoscopic 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 head to emit an ultrasonic signal for detection; in the second detection mode, the probe control unit controls the second acoustic head to emit an ultrasonic signal for detection.

[0009] According to the laparoscopic ultrasound probe shown in the above embodiments, the acoustic head section has both a first acoustic head and a second acoustic head at the same time. The first acoustic head and the second acoustic head are both provided on the outer side of the acoustic head base and on opposite sides of the acoustic head base. Based on this, the operator can rotate the acoustic head base to make the first acoustic head and the second acoustic head face the same detection area successively. Moreover, the laparoscopic 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 ultrasonic signal to the same detection area for detection; in the second detection mode, the probe control unit can control the second acoustic head to emit an ultrasonic signal to the same detection area for detection. Since the central frequencies of the first acoustic head and the second acoustic head are different, the first acoustic head and the second acoustic head can successively detect the same detection area, and the detection depths of the same detection area are different.

[0010] In some embodiments, in the first detection mode, the probe control unit controls the second acoustic head not to emit an ultrasonic signal for detection; in the second detection mode, the probe control unit controls the second acoustic head to emit an ultrasonic signal for detection.

[0011] In some embodiments, the first acoustic head and the second acoustic head are arranged on opposite sides of the acoustic head base, including: the first acoustic head and the second acoustic head are respectively located at different positions in the circumferential direction of the acoustic head base. When the acoustic head base is in a static state, the orientations of the first acoustic head and the second acoustic head are different, so that when the operator rotates the acoustic head base, the emission surfaces of the first acoustic head and the second acoustic head can successively face the same detection area.

[0012] In some embodiments, in the axial direction, at least a part of the first acoustic head and at least a part of the second acoustic head are located in the same length segment of the acoustic head base.

[0013] In some embodiments, in the axial direction, the first acoustic head and the second acoustic head are located in the same length segment of the acoustic head base; or, in the axial direction, the length segment of the first acoustic head in the acoustic head base is located within the length segment of the second acoustic head in the acoustic head base; or, in the axial direction, the length segment of the second acoustic head in the acoustic head base is located within the length segment of the first acoustic head in the acoustic head base.

[0014] In some embodiments, the emitting surfaces of the first acoustic head and the second acoustic head face away from each other in the circumferential direction of the acoustic head base.

[0015] 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.

[0016] In some embodiments, the central frequency of the first acoustic head is 5 MHz - 10 MHz, and the central frequency of the second acoustic head is 12 MHz - 20 MHz; or, the central frequency of the first acoustic head is 12 MHz - 20 MHz, and the central frequency of the second acoustic head is 5 MHz - 10 MHz.

[0017] For the above purposes, some embodiments of the present application provide an ultrasonic device for communicating and connecting with a laparoscope, including:

[0018] A host, the host having a main control unit and an instruction input component;

[0019] And the laparoscopic ultrasonic probe as described in any one of the above;

[0020] The main control unit is communicatively connected to the probe control unit, and the instruction input component is for an operator to input ultrasonic operation instructions.

[0021] According to the ultrasonic device shown in the above embodiments, wherein the acoustic head section of the laparoscopic ultrasonic probe simultaneously has a first acoustic head and a second acoustic head. Both the first acoustic head and the second acoustic head are provided on the outer side surface of the acoustic head base and are located on opposite sides of the acoustic head base. Based on this, the operator can rotate the acoustic head base to make the first acoustic head and the second acoustic head face the same detection area successively. Moreover, the main control unit can control the laparoscopic ultrasonic probe to execute a first detection mode or a second detection mode. In the first detection mode, the probe control unit can control the first acoustic head to emit ultrasonic signals to the same detection area for detection; in the second detection mode, the probe control unit can control the second acoustic head to emit ultrasonic signals to the same detection area for detection. Since the central frequencies of the first acoustic head and the second acoustic head are different, the first acoustic head and the second acoustic head can successively detect the same detection area, and the depths of detection of the same detection area are different.

[0022] In some embodiments, the ultrasonic operation instructions include a first detection mode instruction and a second detection mode instruction;

[0023] 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 to drive the first acoustic head to emit ultrasonic signals for detection;

[0024] When the main control unit receives the second detection mode instruction, the main control unit controls the probe control unit to send a second control signal to the second sound head to drive the second sound head to emit an ultrasonic signal for detection. Description of the Drawings

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings through specific embodiments. Similar elements in different embodiments are labeled with related similar element numbers. In the following embodiments, many details are described to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of these features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification to avoid the core part of the present application being overwhelmed by excessive description. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0030] In addition, 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 also be reordered or adjusted in a manner obvious to those skilled in the art. Therefore, the various sequences in the specification and drawings are only for clearly describing a certain embodiment and do not mean that they are necessary sequences, unless it is stated that a certain sequence must be followed.

[0031] The serial numbers assigned to components in this document itself, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in this application, unless otherwise specified, both include direct and indirect connection (coupling).

[0032] In order to be able to more clearly obtain the condition of a certain area (such as the liver) in the abdominal cavity of a detection object (human or animal), some embodiments of the present application provide a laparoscopic ultrasound probe. This laparoscopic ultrasound probe uses at least two acoustic heads with different center frequencies and, through a rotational change method, enables the two acoustic heads to detect at different depths for the same detection area, so as to obtain more comprehensive detection results, comprehensively check the internal organs, help doctors complete the diagnosis, improve the success rate of the operation, and bring better prognosis to patients.

[0033] Please refer to Figure 1 , this laparoscopic ultrasound probe includes a probe control unit 1 (please see Figure 4 ), an acoustic head section 2, a bending section 3 connected to the acoustic head section 2, an insertion section 5 connected to the bending section 3, and a handle assembly 4 connected to the insertion section 5. When the bending section 3 bends, the orientation of the acoustic head section 2 will also change accordingly. The handle assembly 4 includes a control component 41 and a worm and gear transmission mechanism 42. The worm wheel 422 of the worm and gear transmission mechanism 42 is connected to the insertion section 5. When the worm wheel 422 rotates, it can drive the insertion section 5, the bending section 3, and the acoustic head section 2 to rotate as a whole.

[0034] The control component 41 includes a control element 411 for the operator to input operation instructions. The control element 411 drives the rotation of the worm 421 of the worm and gear transmission mechanism 42 in an electric control manner. For example, the control element 411 is various physical buttons or virtual buttons, etc. The operator can input operation instructions, such as rotation instructions, through the control element 411. The control component 41 may further include a motor 412. The control element 411 can be electrically connected to the motor 412 to control the operation of the motor 412. The output end of the motor 412 can be linked with the worm 421, so that the motor 412 drives the worm 421 to rotate, and further drives the worm wheel 422 of the worm and gear transmission mechanism 42 to rotate.

[0035] Alternatively, the control element 411 can also form a linkage structure with the worm 421 of the worm and gear transmission mechanism 42, so that the operator can drive the rotation of the worm 421 in a manual driving manner, and further drive the worm wheel 422 of the worm and gear transmission mechanism 42 to rotate. In this manual driving method, the control element 411 can be a knob or other manual control elements.

[0036] The acoustic head section 2 can be inserted into the abdominal cavity of the detection object for detection. The probe control unit 1 is used to control each acoustic head on the acoustic head section 2. In some embodiments, the probe control unit 1 can be arranged in the handle assembly 4.

[0037] In addition, in other embodiments, the laparoscopic ultrasound probe may also include other components according to other requirements. For example, please refer to Figure 1 , in some embodiments, the laparoscopic ultrasound probe may further include a connecting cable 6, etc.

[0038] Please refer to Figure 2 and Figure 3 , in some embodiments, the probe head section 2 has a probe head base 21, a first probe head 22, and a second probe head 23. Both the first probe head 22 and the second probe head 23 are communicatively connected to the probe control unit 1 (see Figure 4 ). The center frequencies of the first probe head 22 and the second probe head 23 are different so that the first probe head 22 and the second probe head 23 can respectively detect different depths. In other embodiments, the probe head base 21 may also have a third probe head or more probe heads. These probe heads can be mounted on the probe head base 21 and have different center frequencies.

[0039] Please continue to refer to Figure 2 and Figure 3, in some embodiments, the acoustic head segment 2 can rotate axially under the control of an operator (which can be a doctor or other person). For example, in some embodiments, this rotation can be the rotation of the acoustic head segment 2 around the axis of the acoustic head base 21. The axial direction of the acoustic head segment 2 refers to the direction on the axis of the acoustic head base 21, pointing from one end close to the bending segment 3 to the end away from the bending segment 3. The first acoustic head 22 and the second acoustic head 23 are both arranged on the outer side surface of the acoustic head base 21 along the axial direction of the acoustic head base 21. The so-called outer side surface of the acoustic head base 21 refers to the circumferential outer wall surrounding the axis of the acoustic head base 21, excluding the end face of the acoustic head base 21 at the end away from the bending segment 3. At the same time, the first acoustic head 22 and the second acoustic head 23 are arranged on different sides (i.e., opposite sides) of the acoustic head base 21. Based on this, the operator can change the orientation of the acoustic head base 21 by rotating the acoustic head segment 2 (such as controlling the acoustic head base 21 to rotate by the handle assembly 4), so that the first acoustic head 22 and the second acoustic head 23 can successively face the same detection area, and then can successively detect the same detection area. The first acoustic head 22 and the second acoustic head 23 facing the same detection area means that the emission surfaces (i.e., the areas on the acoustic head that emit and receive ultrasonic signals) of each acoustic head face the same detection area. The same detection area is a certain area range A on the surface of the viscera (such as the liver) in the target abdominal cavity. When the first acoustic head 22 and the second acoustic head 23 face the same direction in the abdominal cavity, the surface ranges of the viscera wall detected by the first acoustic head 22 and the second acoustic head 23 at least partially overlap, and this overlapping part is the same detection area. Since the central frequencies of the first acoustic head 22 and the second acoustic head 23 are different, when the first acoustic head 22 and the second acoustic head 23 respectively face the same detection area, they can respectively detect different depths of the same detection area, so as to obtain the image conditions of the tissues corresponding to different depths in the same detection area.

[0040] Among these acoustic heads of the present application, the acoustic head with a smaller central frequency has better penetration, a larger imaging range, and can detect deeper tissues. For example, it can clearly see deep lesions in the liver. And the acoustic head with a larger central frequency has better images, but poorer penetration, and can be used to detect superficial tissues, such as detecting micro-lesions in superficial areas of the liver such as the liver capsule.

[0041] Specifically, please refer to Figure 2 , in some embodiments, by rotating the acoustic head segment 2, the first acoustic head 22 can be made to face the detection area A for the first image detection. After that, please refer to Figure 3 , the acoustic head segment 2 can be continuously rotated to make the second acoustic head 23 face the detection area A for the second image detection. Although these two image detections are both carried out for the same detection area A, the final obtained images are from tissues at different depths, so the image contents are also different, and the viscera can be more comprehensively screened to help the doctor complete the diagnosis.

[0042] Please refer to Figure 2 andFigure 3 In some embodiments, the central frequency of the first ultrasonic probe 22 is 5 MHz - 10 MHz, and the central frequency of the second ultrasonic probe 23 is 12 MHz - 20 MHz. In this embodiment, the central frequency of the first ultrasonic probe 22 is less than that of the second ultrasonic probe 23. That is, the first ultrasonic probe 22 is used for deep scanning, and the second ultrasonic probe 23 is used for superficial scanning. Of course, in other embodiments, the central frequency of the first ultrasonic probe 22 may also be greater than that of the second ultrasonic probe 23. For example, in some embodiments, the central frequency of the first ultrasonic probe 22 is 12 MHz - 20 MHz, and the central frequency of the second ultrasonic probe 23 is 5 MHz - 10 MHz.

[0043] Please refer to Figure 2 and Figure 3 In some embodiments, the first ultrasonic probe 22 may specifically be a convex array probe, and the second ultrasonic probe 23 may specifically be a linear array probe. In addition, in other embodiments, the first ultrasonic probe 22 may specifically be a linear array probe, and the second ultrasonic probe 23 may specifically be a convex array probe, or both the first ultrasonic probe 22 and the second ultrasonic probe 23 may be linear array probes, or both the first ultrasonic probe 22 and the second ultrasonic probe 23 may be convex array probes, or the first ultrasonic probe 22 and the second ultrasonic probe 23 may be other types of probes.

[0044] On the other hand, the first ultrasonic probe 22 and the second ultrasonic probe 23 can be arranged arbitrarily on the outer side surface of the probe base 21, as long as the operator can rotate the position of the probe base 21 (such as controlling the probe base 21 to rotate by itself through the handle assembly 4), so that the first ultrasonic probe 22 and the second ultrasonic probe 23 can face the same detection area A successively, and then can detect the same detection area A successively.

[0045] Please refer to Figure 2 and Figure 3 In some more specific embodiments, the first ultrasonic probe 22 and the second ultrasonic probe 23 are respectively located in different directions in the circumferential direction of the probe base 21. For example, the positions of the first ultrasonic probe 22 and the second ultrasonic probe 23 are distributed around the axis of the probe base 21. When the probe base 21 is static, the emission surfaces 221 of the first ultrasonic probe 22 and the emission surface 231 of the second ultrasonic probe 23 face different detection directions, so that the emission surfaces 221 of the first ultrasonic probe 22 and the emission surface 231 of the second ultrasonic probe 23 can face the same detection area A successively when the probe base 21 rotates.

[0046] Further, in some embodiments, in the axial direction of the probe base 21, at least a part of the first ultrasonic probe 22 and at least a part of the second ultrasonic probe 23 are located within the same length segment of the probe base 21. That is, as Figure 2 and Figure 3As shown, the set positions of the first acoustic head 22 and the second acoustic head 23 at least partially overlap axially on the acoustic head base 21. In this way, when the acoustic head base 21 rotates to a set angle, the emission surfaces 221 of the first acoustic head 22 and the emission surfaces 231 of the second acoustic head 23 can at least cover a part of the same area, reducing other adjustment actions of the operator.

[0047] In some embodiments, axially on the acoustic head base 21, the emission surfaces 221 of the first acoustic head 22 and the emission surfaces 231 of the second acoustic head 23 are located in the same length segment of the acoustic head base 21; or, axially on the acoustic head base 21, the length segment of the acoustic head base 21 where the emission surface 221 of the first acoustic head 22 is located is within the length segment of the acoustic head base 21 where the emission surface 231 of the second acoustic head 23 is located; or, axially on the acoustic head base 21, the length segment of the acoustic head base 21 where the emission surface 231 of the second acoustic head 23 is located is within the length segment of the acoustic head base 21 where the emission surface 221 of the first acoustic head 22 is located. In these embodiments, when the acoustic head base 21 rotates to a set angle, the emission surfaces 221 of the first acoustic head 22 and the emission surfaces 231 of the second acoustic head 23 can face the same area, and there is no need to additionally adjust the positions of the first acoustic head 22 or the second acoustic head 23 axially forward or backward, etc.

[0048] Furthermore, in some embodiments, the angle difference between the first acoustic head 22 and the second acoustic head 23 can be set arbitrarily. Please refer to Figure 2 and Figure 3 , in some embodiments, the emission surfaces 221 of the first acoustic head 22 and the emission surfaces 231 of the second acoustic head 23 face away from each other circumferentially on the acoustic head base 21. For example, by rotating the acoustic head base 21 by 180°, the emission surfaces 231 of the second acoustic head 23 can face the same direction as the emission surfaces 221 of the first acoustic head 22. Among them, when the emission surfaces 221 of the first acoustic head 22 and the emission surfaces 231 of the second acoustic head 23 are arranged to face away from each other circumferentially on the acoustic head base 21, the circumferential space of the acoustic head base 21 can be fully utilized, so that the first acoustic head 22 and the second acoustic head 23 are spaced farther apart, which is more convenient for the installation of the first acoustic head 22 and the second acoustic head 23 on the acoustic head base 21 and also reduces the installation difficulty.

[0049] On the other hand, in some embodiments, in order to control the first acoustic head 22 and the second acoustic head 23, the laparoscopic 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 head 22 to emit an ultrasonic signal for detection. In the second detection mode, the probe control unit 1 controls the second acoustic head 23 to emit an ultrasonic signal for detection. With the setting of 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 positions of the first acoustic head 22 and the second acoustic head 23 to prevent the first acoustic head 22 or the second acoustic head 23 from being invalidly activated and wasting energy.

[0050] Further, 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 not to emit ultrasonic signals for detection.

[0051] Specifically, in some embodiments, when the emitting surface 221 of the first acoustic head 22 faces the detection area, the operator can activate the first detection mode. At this time, the probe control unit 1 controls the first acoustic head 22 to emit ultrasonic signals for detection, and the obtained image is the image detected by the first acoustic head 22. At this time, the second acoustic head 23 is not activated and there is no image feedback, which can avoid the influence of the image detected by the second acoustic head 23 on the doctor's judgment of the image detected by the first acoustic head 22. On the contrary, when the emitting surface 231 of the second acoustic head 23 faces the detection area, the operator can activate the second detection mode. At this time, the probe control unit 1 controls the second acoustic head 23 to emit ultrasonic signals for detection, and the obtained image is the image detected by the second acoustic head 23. At this time, the first acoustic head 22 is not activated and there is no image feedback, which can avoid the influence of the image detected by the first acoustic head 22 on the doctor's judgment of the image detected by the second acoustic head 23.

[0052] In addition, some embodiments of the present application provide an ultrasonic device for communication connection with a laparoscope. The ultrasonic device includes a host and a laparoscopic ultrasonic probe as described in any one of the above. The host has a main control unit and an instruction input component. The instruction input component can adopt, but is not limited to, structures such as physical buttons, virtual buttons, voice control units, and gesture capture units that can implement instruction input. The main control unit is communicatively connected to the probe control unit 1, and the instruction input component is for the operator to input ultrasonic operation instructions.

[0053] Further, in some embodiments, the ultrasonic operation instructions include a first detection mode instruction and a second detection mode instruction:

[0054] When the main control unit receives the first detection mode instruction, the main control unit controls the probe control unit 1 to send a first control signal to the first acoustic head 22 to drive the first acoustic head 22 to emit ultrasonic signals for detection;

[0055] When the main control unit receives the second detection mode instruction, the main control unit controls the probe control unit 1 to send a second control signal to the second acoustic head 23 to drive the second acoustic head 23 to emit ultrasonic signals for detection.

[0056] The above uses specific examples to elaborate on the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the technical field to which the present invention belongs, according to the idea of the present invention, several simple deductions, deformations or substitutions can also be made.
