[0032] In order to provide a further understanding of the purpose, structure, features and functions of the present invention, the following detailed description is given in conjunction with the embodiments.

[0033] Please also see Figure 1 , Figure 2A , Figure 2B , Figure 2C and Figure 3 , Figure 1 is a functional block diagram of a multifunctional probe according to an embodiment of the present invention, Figure 2A is a schematic diagram of the appearance of a multifunctional probe according to an embodiment of the present invention, Figure 2B : is a schematic diagram of the appearance of a multifunctional probe (configured with an array probe and an electronic stethoscope / electrocardiogram electrode patch) according to another embodiment of the present invention. Figure 2C is a multifunctional probe according to another embodiment of the present invention, Figure 3 1 is a schematic diagram of the appearance of a signal detector according to an embodiment of the present invention. The multifunctional probe 100 includes a hand-held housing 110, a signal detector 120, an array probe 130, a multiplexer 140, a switching circuit 150, a transmitting circuit 160, a receiving circuit 170 and a processor 180. The signal detector 120 is flexibly arranged on the hand-held housing 110, and the array probe 130 is arranged at one end or the second end of the hand-held housing 110. For example, the signal detector 120 is flexibly arranged at the first end of the hand-held housing 110, that is, the array probe 130 and the signal detector 120 are respectively arranged at opposite ends of the hand-held housing 110. In addition, the signal detector 120 can also be flexibly arranged at other parts of the hand-held housing 110, such as the middle part of the hand-held housing 110, or the arrangement position can be close to the array probe 130 or far away from the array probe 130, depending on the design requirements of the industry.

[0034] See also Figure 2A , Figure 2B , Figure 2CThe signal detector 120 is fixed on the hand-held housing 110 or the first end in a flexible configuration. In other words, the flexible configuration includes flexibility in addition to the wire. Flexibility refers to the ability of an object to maintain its shape before deformation after the force is lost. For example, the outer sheath material of the wire is rubber, which has good elasticity. It will deform after being subjected to stress, but the shape will return to its original state after the stress disappears, which effectively increases the flexibility of the signal detector 120. The signal detector 120 can be applied to a one-dimensional array transducer, a 1.5D transducer, a two-dimensional array transducer, an array transducer of two or more dimensions, a linear transducer, an arc transducer, a circular transducer, a hyperbolic transducer, a transducer with two or more curvatures, a spherical transducer, an aspherical transducer or a composite transducer, wherein the composite transducer can be an array transducer that combines an arc and a linear shape, and the user can replace the type of transducer as needed, which effectively increases flexibility.

[0035] In one embodiment, if Figure 1 As shown, the array probe 130 is electrically coupled to the signal detector 120, the multiplexer 140 is electrically coupled to the array probe 120 and the signal detector 130, the switching circuit 150 is electrically coupled to the multiplexer 140, the transmitting circuit 160 is electrically coupled to the switching circuit 150, the receiving circuit 170 is electrically coupled to the switching circuit 150, and the processor 180 is electrically coupled to the array probe 130 and the signal detector 120. Further, in the field of circuits, coupling includes direct coupling and indirect coupling, that is, it includes whether there are other components between the coupling of two electronic components. In other words, electronic component A is indirectly coupled to electronic component C through electronic component B, that is, electronic component A is directly coupled to electronic component B and electronic component B is directly coupled to electronic component C.

[0036] In one embodiment, if Figure 1As shown, the first contact time of the signal detector 120 contacting the biological body can at least partially overlap with the second contact time of the array probe 130 contacting the biological body, and the signal detector 12 and the array probe 130 generate a first electronic signal 1ES. Further, the signal detector 12 and the array probe 130 can simultaneously send and / or receive signals to the tissue of the biological body, for example, the above-mentioned signal can be an ultrasonic signal or an ultrasonic echo signal. The multiplexer 140 is used to at least include the function of receiving and transmitting the first electronic signal 1ES. The signal detector 120 and the array probe 130 can convert the first electronic signal 1ES into an ultrasonic signal, and can also convert it into the first electronic signal 1ES according to the ultrasonic echo signal reflected by the tissue of the biological body, and send and receive it to the multiplexer 140, wherein the processor 180 provides a detection result according to the first electronic signal 1ES, and the processor 180 calculates the detection result of the first electronic signal 1ES according to the built-in hardware or software, wherein the detection result includes the position, distance or depth information of at least a part of the biological tissue. The switching circuit 150 can switch the multi-function probe 100 to a transmitting mode or a receiving mode, and the switching circuit 150 at least transmits and receives the second electronic signal 2ES; in other words, the switching circuit 150 can also have two modes, a transmitting mode and a receiving mode, so that the multi-function probe 100 is in a transmitting mode or a receiving mode.

[0037] In one embodiment, when the signal detector 120 is, for example, a blood flow meter, the signal detector 120 penetrates into the superficial layer of human tissue in an invasive manner. When the switching circuit 150 is in the transmitting mode, the switching circuit 150 receives the transmitting signal 1LS generated by the transmitting circuit 160, and causes the signal detector 120 to generate an ultrasonic signal and send it to the tissue of the organism. When the switching circuit 150 is in the receiving mode, the array probe 130 can receive the ultrasonic echo signal reflected by the tissue of the organism, and obtain the position, distance or depth information of at least a part of the tissue of the organism through the coupled multiple functional circuits (such as the multiplexer 140, the switching circuit 150, the transmitting circuit 160, the receiving circuit 170 and the processor 180), thereby effectively increasing the detection accuracy. In addition, the signal detector 120 and the array probe 130 of the present invention share multiple functional circuits (such as a multiplexer 140, a switching circuit 150, a transmitting circuit 160, a receiving circuit 170 and a processor 180) to achieve the function of simultaneously detecting the position, distance or depth information of at least a part of the biological tissue, thereby effectively reducing the circuit cost and volume.

[0038] In one embodiment, if Figure 1As shown, the detection result provided by the processor 180 according to the first electronic signal 1ES includes the distance between the signal detector 120 and the tissue, wherein when the distance between the signal detector 120 and the tissue is lower than the preset distance value, a first sound signal is generated, and the frequency of the first sound signal is negatively correlated with the distance between the signal detector 120 and the tissue. For example, the characteristics of the first sound signal show that when the signal detector 120 is too close to the target object, a warning sound is issued like a reversing radar, and the distance between the signal detector 120 and the tissue is inversely proportional to the sound frequency (for example, the closer the distance, the higher the sound frequency).

[0039] In one embodiment, the signal detector 120 may be a bio-sound monitor, wherein the first electronic signal 1ES is a second sound signal or an electronic sound signal. Figure 2B The bio-sound monitor includes an electronic stethoscope or an electrocardiogram (ECG) electrode patch. The electrocardiogram (ECG) electrode patch is a diagnostic technology that records the electrophysiological activity of the heart in time units through the body wall and captures and records it through electrodes in contact with the skin. The multi-function probe 100 proposed by the present invention includes an array probe 120 and a signal detector 130 on or at both ends of its handheld shell, which effectively increases its applicability.

[0040] In one embodiment, see Figure 2A , Figure 2B , Figure 2C and Figure 3 The signal detector 120 and the array probe 130 are detachable configurations. For example, the signal detector 120 can be a blood flow meter 121, an electronic stethoscope or an electrocardiogram electrode patch. The array probe 130 can be a one-dimensional array transducer, a 1.5D transducer, a two-dimensional array transducer, an array transducer of two or more dimensions, a linear transducer, an arc transducer, a circular transducer, a hyperbolic transducer, a transducer of two or more curvatures, a spherical transducer, an aspherical transducer or a composite transducer, wherein the composite transducer can be an array transducer that is a combination of an arc and a linear transducer. For example, the blood flow meter 121 can be a measuring instrument of the model Transonic HT 300 designed for the needs of various surgeries, and its function is to measure and monitor the blood flow of various blood vessels, including arteries, veins, and catheters used during surgery. Therefore, the blood flow of the blood vessels or organs connected during surgery can be accurately evaluated. Simply hook the measuring probe onto the blood vessel to be measured, and you can see the quantitative data (ml / min) of the blood vessel on the instrument. If you use an in vitro pipeline measurement sensor, clip the sensor onto the pipeline, and you can also clearly see the flow rate of the liquid flowing in the pipeline. Figure 2CAs shown, in another embodiment of the present application, the position of the signal detector 120 is not limited to a specific position of the hand-held housing 110 , and the signal detector can be located anywhere on the hand-held housing, such as being configured at the middle position of the hand-held housing 110 .

[0041] In one embodiment, see Figure 3 The outer part of the blood flow meter 121 is covered with an outer sleeve needle 123, and the outer sleeve needle 123 can fix the position of the blood flow meter 121. The blood flow meter 121 obtains the A mode signal (waveform) and the blood flow signal (waveform), and converts the A mode signal and the blood flow signal into a first sound signal or displays a numerical value. This reminds the user of the proximity or distance between the needle of the blood flow meter 121 and the target object. The ultrasonic probe is used to detect specific human tissues such as nerves, fat tissues, etc. Because of different frequency characteristics, the blood flow meter 121 uses the Doppler principle to obtain blood flow characteristics. The blood flow meter 121 generates an ultrasonic signal, and the array probe 130 receives the ultrasonic echo signal. The processor 180 of the multi-function probe 100 can determine whether the heart is beating through an electrocardiogram based on the ultrasonic signal generated by the blood flow meter 121 and the ultrasonic echo signal received by the array probe 130, especially in the situation where the pulse cannot be felt. The array probe 130 can be used to determine whether there is pericardial effusion in the structure through images, with emphasis on the pericardium with high echo in the outer circle and the diameter of the aortic root to see whether there is obvious enlargement (for example, blood reflux or high resistance).

[0042] In one embodiment, the first electronic signal 1ES includes at least one of an A-mode signal, a B-mode imaging signal, and a blood flow signal. The A-mode signal is a simple ultrasound wave type. A single sensor scans a line through the body, and the echo is plotted on the screen as a function of depth. The therapeutic ultrasound for specific tumors or stones is also an A-mode signal mode, which can accurately locate the destructive wave energy. In B-mode imaging ultrasound, the signal detector 120 simultaneously scans a plane through the body through a linear array of transducers, and a two-dimensional image can be seen on the screen, effectively increasing the applicability of the multifunctional probe 100. For example, the array probe 130 obtains a B-mode image to obtain the initial relevant position of the affected part, and penetrates the superficial layer of the human tissue through the outer cannula needle 123. Then, the blood flow meter 121 (for example, yellow) in the outer cannula needle 123 can obtain waveform signals such as medical imaging information related to blood vessels and nerve tissues. The signal detector 120 uses the Doppler effect to measure and display blood flow, which can be used to evaluate whether the structure (such as blood) moves toward or away from the probe, and the relative speed of blood and blood vessels. For another example, the array probe 130 obtains a B-mode image to obtain the preliminary relative position of the affected part, and penetrates the superficial layer of the human tissue through the outer sheath needle 123. Then, the blood flow meter 121 in the outer sheath needle 123 sends an ultrasonic signal, and the array probe 130 receives the ultrasonic echo signal reflected by the ultrasonic signal, thereby accurately obtaining the relative position of the outer sheath needle 123 and the blood flow meter 121 in the B-mode image.

[0043] It should be noted that in the above embodiments, the description of the multiplexer 140, the switching circuit 150, the transmitting circuit 160, the receiving circuit 170, and the processor 180 does not limit the technical scope of the present invention. In practice, as long as the first contact time of the signal detector contacting the biological body can at least partially overlap with the second contact time of the array probe contacting the biological body and generate a first electronic signal, it can be used. That is, the present invention can be summarized as: a multifunctional probe, including a hand-held shell, a signal detector and an array probe, wherein the signal detector is flexibly configured on the hand-held shell or the first end, the array probe is configured at one end of the hand-held shell, the array probe is electrically coupled to the signal detector, the first contact time of the signal detector and the array probe contacting the biological body at least partially overlaps with the second time of the array probe, and the signal detector and the array probe generate a first electronic signal. In this way, the detection efficiency and accuracy can be effectively increased.

The third contact time of the bio-sound monitor 590 contacting the biological body can at least partially overlap the first contact time of the signal detector 120 contacting the biological body and the second contact time of the array probe 130 contacting the biological body. The signal detector 120, the array probe 130 and the bio-sound monitor 590 generate a first electronic signal 1ES. Furthermore, the signal detector 120, the array probe 130 and the bio-sound monitor 590 can simultaneously send and / or receive a signal to the tissue of the organism. For example, the bio-sound monitor 590 includes an electronic stethoscope or an electrocardiogram (ECG) electrode patch. The electrocardiogram (ECG) electrode patch is a diagnostic technology that records the electrophysiological activity of the heart in units of time through the body wall and captures and records it through electrodes that contact the skin. The electrophysiological activity of the heart recorded by the multi-function probe 500 can be converted into an electrocardiogram. Other related technical features such as Figure 1 The embodiments are described in detail and will not be repeated here.
