[0026] In order to thoroughly understand the implementation of the utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the utility model is not limited to the specific details familiar to those skilled in the art. The preferred implementation of the utility model is described in detail below, but in addition to these detailed descriptions, the utility model can also have other implementations.

[0027] An ultrasonic probe 10 is provided in one embodiment of the utility model, and the ultrasonic probe 10 can be used in the medical field, the mechanical manufacturing field, etc. The following will introduce an ultrasonic probe 10 according to an embodiment of the utility model in detail with reference to the accompanying drawings. Taking the ultrasonic probe 10 used in the medical field as an example, the ultrasonic probe 10 can be installed at the end of an ultrasonic endoscope probe to detect and inspect the internal organs of the patient's body.

[0028] See also Figure 1 The ultrasonic probe 10 includes a detection part 111, a first base 112 and a pressure detection part 12. The detection part 111 and the first base 112 enclose a receiving cavity 113. The pressure detection part 12 is disposed in the receiving cavity 113 and contacts the detection part 111.

[0029] The shape of the first base 112 can be circular, plate-shaped or long strip-shaped. The cross-sectional shape of the detection portion 111 can be arc-shaped, rectangular or square-shaped, etc., preferably arc-shaped. When the cross-sectional shape of the detection portion 111 is arc-shaped, the specific shape of the detection portion 111 can be arched. The detection portion 111 is used to contact the detection position. When the detection portion 111 is subjected to pressure, the detection portion 111 transmits the pressure to the pressure detection portion 12, and the pressure detected by the pressure detection portion 12 can sense the magnitude of the pressure.

[0030] When the number of the pressure detecting portion 12 disposed in the accommodating cavity 113 is one, the pressure detecting portion 12 may be disposed at a middle position of the first base 112 .

[0031] Combined with reference Figure 1 and Figure 3 , the detection part 111 and the first base 112 can be connected by a connecting plate 114. The detection part 111, the first base 112 and the connecting plate 114 cooperate to form a receiving cavity 113, and one or more supporting members 1131 can be arranged in the receiving cavity 113. The setting direction of the supporting member 1131 is perpendicular to the setting direction of the pressure detection part 12, and the two ends of the supporting member 1131 are respectively fixed to the connecting plate 114, so that the supporting member 1131 can prop up the receiving cavity 113 and have a higher strength, thereby increasing the stability of the ultrasonic probe 10 and effectively improving the accuracy of the detection result.

[0032] In the ultrasonic probe 10 of the utility model, when the detection part 111 is subjected to pressure, the pressure can be transmitted to the pressure detection part 12 in contact with the detection part 111. The pressure detection part 12 can detect and record the pressure in real time, thereby facilitating calculations based on the recorded pressure, such as calculating the shear modulus using the strain caused by the pressure, thereby effectively improving the accuracy of the detection results of the ultrasonic probe 10.

[0033] In one embodiment of the present invention, refer to Figure 2 There are multiple pressure detection parts 12, and the multiple pressure detection parts 12 are arranged on the first base 112 at intervals.

[0034] The multiple pressure detection parts 12 can adjust the specific position of the pressure detection part 12 on the first base 112 according to the shape of the detection part 111.

[0035] Exemplarily, when the cross-sectional shape of the detection part 111 is rectangular, multiple pressure detection parts 12 can be arranged in the central area of ​​the first base 112, so that when the detection part 111 contacts the detection position, multiple pressure detection parts 12 can detect the pressure applied to ensure the accuracy of the detection result.

[0036] The average value or median value of the pressures acquired by the multiple pressure detection parts 12 may be used as the overall pressure acquired by the ultrasound probe 10 .

[0037] With such an arrangement, the overall pressure exerted on the ultrasonic probe 10 can be comprehensively determined based on the pressure exerted on the multiple pressure detection parts 12, thereby further improving the accuracy of the detection result of the ultrasonic probe 10.

[0038] In one embodiment of the present invention, refer to Figure 2 , multiple pressure detection parts 12 are evenly distributed on the first base 112 according to a preset arrangement.

[0039] The preset arrangement is represented by determining the positions of the plurality of pressure detection parts 12 according to different detection targets.

[0040] Exemplarily, when the detection target is of irregular shape, multiple pressure detection parts 12 can be evenly arranged with the first base 112 as the center, so that when the detection target is detected at different angles, the ultrasonic probe 10 can detect the pressure results, effectively ensuring the accuracy of the detection results.

[0041] With such a configuration, the pressure detection part 12 can be arranged according to the actual needs, thereby avoiding the accuracy of the detection result being affected by the arrangement position of the pressure detection part 12, and effectively ensuring the reliability and accuracy of the detection result of the ultrasonic probe 10.

[0042] In one embodiment of the present invention, refer to Figure 2 The detection part 111 has an inner wall facing the first base 112 , the pressure detection part 12 includes a pressure sensor 121 and a second base 122 , the pressure sensor 121 and the second base 122 are elastically connected, and the pressure sensor 121 contacts the inner wall of the detection part 111 .

[0043] The elastic connection can be used to apply force to the pressure sensor 121, so that the pressure sensor 121 is stably in contact with the detection part 111. The pressure sensor 121 can achieve point contact with the inner wall of the detection part 111, thereby reducing the contact area between the two, reducing friction, and increasing the accuracy of the detection result.

[0044] The second base 122 may be in a circular, plate-shaped, or long strip shape, etc. The size of the second base 122 is smaller than that of the first base 112 .

[0045] With such arrangement, when the pressure sensor 121 is subjected to pressure, it can move toward the second base 122 , so that the pressure sensor 121 has sufficient elastic deformation space, thereby making the ultrasonic probe 10 have a reasonable and compact structural layout.

[0046] In one embodiment of the present utility model, in conjunction with reference to Figure 2 and Figure 3 The pressure detection part 12 also includes a guide rod 123. A through hole (not shown in the through hole diagram) is provided on one side of the pressure sensor 121 close to the guide rod 123. One end of the guide rod 123 is provided in the through hole, and the other end of the guide rod 123 is connected to the second base 122.

[0047] The guide rod 123 has a first end 1231 and a second end 1232. The pressure sensor 121 is disposed at the first end 1231 of the guide rod 123, and the second base 122 is disposed at the second end 1232 of the guide rod 123. When the pressure sensor 121 is subjected to an external force, the pressure sensor 121 can move along the guide rod 123 toward the second base 122, thereby avoiding the situation in which the pressure detected by the pressure detection part 12 is inaccurate due to the pressure sensor 121 moving to other positions or directions in the accommodating cavity 113.

[0048] A gap is provided between the through hole and the guide rod 123 so as to avoid inaccurate detection results due to the friction force generated between the two when the pressure sensor 121 moves along the guide rod 123 .

[0049] In this arrangement, the pressure sensor 121 and the second base 122 are connected by a guide rod 123, which has a guiding function, so that the pressure sensor 121 can move vertically along the direction of the guide rod 123 when subjected to pressure, so as to conveniently and accurately record the pressure received by the pressure sensor 121, thereby improving the accuracy of the detection results of the ultrasonic probe 10.

[0050] In one embodiment of the present utility model, in conjunction with reference to Figure 2 and Figure 3 An elastic member 13 is disposed on the outer sleeve of the guide rod 123 , one end of the elastic member 13 abuts against the second base 122 , and the other end abuts against the pressure sensor 121 .

[0051] The elastic member 13 may be connected to the pressure sensor 121 and the second base 122 respectively, so as to stabilize the abutment between the components of the pressure detection part 12 .

[0052] The elastic member 13 may be a spring or an elastic gasket, etc. In the embodiments of the present application, no limitation is imposed on the type of the elastic member 13. Any device that can be compressed by force to accumulate elastic potential energy is within the protection scope of the present application.

[0053] When external pressure is applied, the elastic member 13 can buffer and absorb part of the pressure, preventing the pressure sensor 121 from being damaged by excessive impact, effectively extending the service life of the pressure sensor 121 and improving its reliability. The elastic member 13 can also enable the pressure sensor 121 to achieve a larger displacement within a certain range, effectively expanding the measurement range of the pressure sensor 121, making it suitable for a wider range of application scenarios. In addition, the elastic member 13 can make the pressure sensor 121 more sensitive to pressure changes, thereby improving the sensitivity and accuracy of the sensor.

[0054] With such arrangement, the elastic member 13 sleeved on the outside of the guide rod 123 enables the pressure sensor 121 to better adapt to contact surfaces of different shapes and curvatures, thereby ensuring close contact between the pressure sensor 121 and the object to be measured, thereby improving the accuracy of the detection result.

[0055] In one embodiment of the present utility model, in conjunction with reference to Figure 2 and Figure 3 The pressure sensor 121 has an arc-shaped portion abutting against the detection portion 111 , and an inner wall of the detection portion 111 is formed with an arc surface, and the arc surface of the detection portion 111 abuts against the arc-shaped portion of the pressure sensor 121 .

[0056] The arcuate portion of the pressure sensor 121 abuts against the inner wall of the detection portion 111 , and the contact position between the two is arc-shaped, thereby better detecting the pressure applied to the pressure sensor 121 and improving the sensitivity and accuracy of the detection result.

[0057] In this way, the arc surface of the detection part 111 abuts against the arc portion of the pressure sensor 121, so that the pressure received can be evenly distributed on the contact surface of the pressure sensor 121, and the received pressure can be better dispersed and balanced, thereby improving the accuracy and stability of the detection result. In addition, it can better adapt to the curvature and deformation of the object being measured, thereby improving the sensitivity and response speed of the pressure sensor 121 to external pressure changes.

[0058] In one embodiment of the present invention, an acoustic window (not shown in the figure) is formed on the detection part 111, and the pressure detection part 12 is in contact with the inner wall of the acoustic window.

[0059] The pressure detection part 12 can be in contact with the inner wall of the acoustic window on the detection part 111, and the position on the inner wall of the acoustic window that is not in contact with the pressure detection part 12 can be sequentially provided with a matching layer, a piezoelectric layer and a backing. The matching layer can be used to improve the transmission efficiency of ultrasonic energy, the piezoelectric layer can be used to generate and receive ultrasonic waves, and the backing layer can be used to absorb backward scattering. The synergistic effect of the above-mentioned matching layer, piezoelectric layer and backing can improve the accuracy of the detection result of the ultrasonic probe 10.

[0060] Optionally, a connection portion may be provided at a position on the inner wall of the acoustic window that is not in contact with the pressure detection portion 12, and a matching layer, a piezoelectric layer, and a backing are sequentially provided in the connection portion. In this way, it is possible to ensure that the matching layer, the piezoelectric layer, and the backing are in closer contact, thereby improving the energy transfer efficiency of the ultrasonic wave, and reducing the gap between the layers, thereby reducing the energy loss and reflection of the ultrasonic wave, and effectively improving the sensitivity and accuracy of the ultrasonic probe 10.

[0061] In this way, an acoustic window is set on the detection part 111, and is in contact with the pressure detection part 12 through the inner wall of the acoustic window. The acoustic window can reduce the attenuation of ultrasonic waves during transmission, and can effectively reduce the reflection and scattering of ultrasonic waves between the pressure detection part 12 and the detection target, thereby improving the accuracy of the detection results.

[0062] In one embodiment of the present invention, the acoustic window is made of elastic material.

[0063] With such a configuration, the acoustic window made of elastic material can better adapt to the irregular shape of the detection target, thereby providing better acoustic coupling, effectively reducing the gap between the ultrasonic probe 10 and the detection target, and greatly improving the transmission efficiency of the ultrasonic wave.

[0064] In one embodiment of the present invention, the first base 112 and the second base 122 are detachably connected.

[0065] The first base 112 and the second base 122 can be connected by threaded connection or snap connection, etc. The detachable connection can flexibly configure the number of pressure detection parts 12, so that the ultrasound probe 10 can be more easily adapted to different needs.

[0066] The detachable connection makes the maintenance or replacement of the ultrasound probe 10 more convenient, effectively saving the user's time and cost, and making the maintenance or replacement process more efficient.

[0067] In this way, the number of pressure detection parts 12 can be flexibly set according to actual usage. In addition, when a component of the pressure detection part 12 fails, it can be convenient for users to repair or replace it in time, effectively improving the practicality of the ultrasonic probe 10.

[0068] An embodiment of the present invention further provides an ultrasonic diagnostic device, which includes the ultrasonic probe 10 as described above.

[0069] The ultrasonic diagnostic device may include an ultrasonic host, and the ultrasonic probe 10 is connected to the ultrasonic host via a cable.

[0070] Optionally, the ultrasonic probe 10 may be a convex array probe, a linear array probe, a phased array probe, a circular array probe, etc. The present application does not impose any limitation on the type of the ultrasonic probe 10 .

[0071] The ultrasonic diagnostic device of the present invention includes the ultrasonic probe 10 as described above. Since the ultrasonic probe 10 has the beneficial effects as described above, the ultrasonic diagnostic device including the ultrasonic probe 10 must also have the beneficial effects as described above.

[0072] An embodiment of the present invention further provides an ultrasonic endoscope, which includes the ultrasonic probe 10 as described above.

[0073] The ultrasonic endoscope may include an insertion portion and a head portion, and the ultrasonic probe 10 may be disposed at the head portion. The ultrasonic probe of this embodiment may be any type of probe mentioned above, such as a convex array probe.

[0074] The detection part 111 of the ultrasonic probe 10 may include an acoustic window, a matching layer, a piezoelectric layer and a backing. The pressure detection part 12 may be disposed in the accommodating cavity 113 formed by the detection part 111 and the first base 112, and abut against the backing of the detection part 111 or the inner wall of the acoustic window of the detection part 111.

[0075] In this way, when the acoustic window of the detection part 111 is subjected to pressure, the pressure can be transmitted to the pressure detection part 12 in contact with the detection part 111, so as to calculate the pressure on the detection part 111. Therefore, when the ultrasonic endoscope is in use, when the acoustic window is deformed to a certain extent, the pressure detection part 12 can calculate the pressure value, effectively ensuring the accuracy and reliability of the ultrasonic endoscope detection results. The acoustic window can be made of a material with a certain elasticity. There is no limitation on the material of the acoustic window, as long as it can meet the pressure provided by the organ tissue measured by the pressure detection part 12.
