Description

Technical Field

[0001] The utility model relates to the technical field of medical ultrasonic imaging, in particular to an ultrasonic transducer, an ultrasonic probe and an ultrasonic system. Background Art

[0002] In the medical field, it is often necessary to quickly screen for lesions in close-range tissues or microscopic tissues at the cellular level in the human body (such as blood vessels). Pulse Doppler (PW) has the ability to select by distance, and can set the size of the sampling volume, adjust its depth and position, and use the gap between emission and reflection to receive frequency-shifted signals, so the measured value is relatively accurate. However, if the small probe of the ultrasonic endoscope is to detect blood flow, the ultrasonic transducer needs to scan the blood vessels in a static state. Since the ultrasonic transducer is in the cavity, the detection end of the ultrasonic transducer only scans in a certain direction when it is static, and it is difficult to find the actual position of the blood vessel, so a single ultrasonic transducer cannot meet the doctor's needs for measuring blood flow in the cavity. Utility Model Content

[0003] Therefore, the technical problem to be solved by the present invention is that the conventional ultrasonic transducer in the prior art can only perform ultrasonic imaging and cannot meet the needs of doctors for measuring intracavitary blood flow.

[0004] To this end, the utility model provides an ultrasonic transducer, comprising:

[0005] The carrier is provided with a first mounting surface and a second mounting surface, and the axes of the first mounting surface and the second mounting surface are arranged to intersect;

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] Example 1

[0040] This embodiment provides an ultrasonic transducer, such as Figure 1 and Figure 2 As shown, it includes a carrier 1 and an ultrasonic transducer assembly 2. Specifically, the carrier 1 is provided with a first mounting surface 12 and a second mounting surface 14, and the axes of the first mounting surface 12 and the second mounting surface 14 are arranged crosswise; the ultrasonic transducer assembly 2 at least includes a first ultrasonic transducer 21 and a second ultrasonic transducer 22, the first ultrasonic transducer 21 is installed on the first mounting surface 12, and the second ultrasonic transducer 22 is installed on the second mounting surface 14.

[0041] The ultrasonic transducer of the above structure integrates the first ultrasonic transducer 21 and the second ultrasonic transducer 22. When in use, the carrier 1 is rotated, and the second ultrasonic transducer 22 is used to detect the tissue around the inner cavity and form a tissue structure diagram. The blood vessel position is obtained according to the tissue structure diagram. After the position of the blood vessel to be measured is found, the angle of the carrier 1 is adjusted, specifically, adjusted to the axis of the second mounting surface 14 to be perpendicular to the outer wall of the blood vessel, so that the emission direction of the second ultrasonic transducer 22 is perpendicular to the blood vessel. At this time, since the axis of the first mounting surface 12 and the axis of the second mounting surface 14 are cross-arranged, the angle between the first ultrasonic transducer 21 and the blood vessel can be obtained, which is convenient for obtaining blood flow information in the blood vessel through the first ultrasonic transducer 21 when the ultrasonic transducer is in pulse Doppler (PW) mode, thereby meeting the needs of doctors and improving the practicality of the ultrasonic transducer.

[0042] It can be explained that the ultrasonic transducer provided in this embodiment further explains the carrier 1. For example, the carrier 1 is a columnar structure, and a mounting groove 13 is provided on the side of the carrier 1. At this time, the second mounting surface 14 is located on the mounting groove 13. It should be explained that the axis of the first mounting surface 12 is defined as the first axis 11, and the axis of the second mounting surface 14 is defined as the second axis 15. The second axis 15 is arranged to intersect with the first axis 11; wherein, the carrier 1 rotates around the first axis 11 under the action of the transmission force or external force.

[0043] Furthermore, in this embodiment, the intersection degree between the first axis 11 and the second axis 15 is limited. Figure 1 and Figure 2 As shown, the range of one angle θ after the first axis 11 and the second axis 15 are intersected is 30° to 60°; preferably, the range of the angle θ after the first axis 11 and the second axis 15 are intersected is 40° to 50°.

[0044] like Figure 1 and Figure 2 As shown, the ultrasonic transducer provided in this embodiment has the first ultrasonic transducer 21 centrally mounted on the first mounting surface 12 , so that the vertical line where the geometric center of the first ultrasonic transducer 21 is located is colinear with the rotation axis of the carrier 1 .

[0045] The ultrasonic transducer of the above structure is configured such that the first ultrasonic transducer 21 is centrally mounted on the first mounting surface 12. When in use, even if the carrier 1 rotates, the first ultrasonic transducer 21 can still emit ultrasonic waves along the first axis 11. That is, during the rotation of the carrier 1, the first ultrasonic transducer 21 can still detect blood flow information, so that the blood flow information measured by the first ultrasonic transducer 21 is more accurate.

[0046] It can be explained that the ultrasonic transducer provided in this embodiment does not limit the structure of the mounting groove 13, and can be formed by one or a combination of V-shaped groove, U-shaped groove, square groove or circular groove. As one implementation method, Figure 1 and Figure 2 As shown, the mounting groove 13 is selected as a V-shaped groove.

[0047] Furthermore, the second mounting surface 14 is not limited and can be an arc-shaped surface or a sector-shaped surface. As one implementation, the second mounting surface 14 is a sector-shaped surface.

[0048] like Figure 1 and Figure 2 As shown, when installing the ultrasonic transducer provided in this embodiment, one end of the carrier 1 should be left empty and the other end should be used to connect with the catheter; and the first installation surface 12 should be set on the side of the carrier 1 away from the catheter.

[0049] like Figure 1 and Figure 2 As shown, in the ultrasonic transducer provided in this embodiment, the first mounting surface 12 is set as the end surface of the carrier 1. For example, the first mounting surface 12 is a circular surface.

[0050] like Figure 1 and Figure 2 As shown, the ultrasonic transducer provided in this embodiment does not limit the number of array elements in the first ultrasonic transducer 21 and the second ultrasonic transducer 22.

[0051] As one implementation manner, the first ultrasonic transducer 21 and / or the second ultrasonic transducer 22 is a single-element ultrasonic transducer.

[0052] As another embodiment, the first ultrasonic transducer 21 and / or the second ultrasonic transducer 22 is a multi-element ultrasonic transducer. When arranged, a plurality of elements are arranged in an array on the installation surface, such as a circular array or a matrix arrangement.

[0053] like Figure 1 and Figure 2 As shown, the ultrasonic transducer provided in this embodiment does not limit the operating frequencies of the multiple ultrasonic transducers in the ultrasonic transducer assembly 2.

[0054] As one of the implementation methods, the working frequencies of the first ultrasonic transducer 21 and the second ultrasonic transducer 22 are different. According to the actual use requirements, two ultrasonic transducers with different frequencies are selected, and the frequency of the selected ultrasonic transducer is between 2M and 60M. Further, the frequency of the ultrasonic transducer is between 10M and 30M. Since the higher the frequency of the ultrasonic wave, the higher the corresponding imaging accuracy; the lower the frequency, the deeper the corresponding penetration depth, therefore, when a more delicate near-field image is needed: for example, to detect lesions of the stomach wall or the inner wall of the blood vessel, a high-frequency ultrasonic transducer can be used; when a deeper far-field image is needed, a low-frequency ultrasonic transducer can be used.

[0055] Specifically, in this embodiment, the first ultrasonic transducer 21 is a high-frequency ultrasonic transducer, and the second ultrasonic transducer 22 is a low-frequency ultrasonic transducer. The ultrasonic transducer can generate ultrasonic waves of various frequencies, and obtain different ultrasonic images through filtering, amplification, sampling, and filtering. Of course, in other optional embodiments, the first ultrasonic transducer 21 is a low-frequency ultrasonic transducer, and the second ultrasonic transducer 22 is a high-frequency ultrasonic transducer.

[0056] In addition, in other optional implementations, the operating frequencies of the first ultrasonic transducer 21 and the second ultrasonic transducer 22 are the same.

[0057] It can be explained that any ultrasonic transducer provided in this embodiment is selected as an ultrasonic transducer of conventional technology. For example, in the first ultrasonic transducer 21 and the second ultrasonic transducer 22, any ultrasonic transducer includes a lens, a mirror, a matching layer and a backing layer.

[0058] It should be noted that, in this embodiment, the first ultrasonic transducer 21 and the second ultrasonic transducer 22 share a backing layer, so as to reduce the volume of the ultrasonic transducer.

[0059] Example 2

[0060] This embodiment provides an ultrasonic transducer, which is compared with the ultrasonic transducer provided in Embodiment 1. Figure 3 As shown, the difference is that a part of the mounting groove 13 is selected as a rectangular groove, so that the second mounting surface 14 in the carrier 1 is set as a stepped mounting surface.

[0061] Specifically, in this embodiment, the plane set on the side of the second mounting surface 14 close to the slot of the mounting groove 13 is higher than the plane set on the side of the second mounting surface 14 away from the slot of the mounting groove 13, and the second ultrasonic transducer 22 is installed on the plane set on the side of the second mounting surface 14 away from the slot of the mounting groove 13.

[0062] Example 3

[0063] This embodiment provides an ultrasonic transducer, which is compared with the ultrasonic transducer provided in Embodiment 1. Figure 4 As shown, the difference is that one of the cut-out surfaces forming the mounting groove 13 is the second mounting surface 14, and the second mounting surface 14 is arranged obliquely, and the other cut-out surface forming the mounting groove 13 is arranged vertically, so that the first mounting surface 12 is a sector-shaped surface.

[0064] Specifically, in this embodiment, after the first ultrasonic transducer 21 is mounted on the first mounting surface 12 , the vertical line where the geometric center of the first ultrasonic transducer 21 is located is collinearly arranged with the rotation axis of the carrier 1 .

[0065] Example 4

[0066] This embodiment provides an ultrasonic probe, including the ultrasonic transducer provided in Embodiment 1, Embodiment 2 or Embodiment 3.

[0067] Example 5

[0068] This embodiment provides an ultrasound system, including the ultrasound probe provided in Embodiment 4.

[0069] It can be explained that, in this embodiment, the carrier 1 is movably arranged on the catheter; the ultrasonic system also includes a driving member, the driving end of the driving member is rotatably arranged, and the driving end of the driving member is connected to the carrier 1 to facilitate subsequent driving of the carrier 1 to rotate around the first axis 11.

[0070] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
