Detailed Description

For a further understanding of the objects, construction, features and functions of the utility model, reference should be made to the following detailed description of the preferred embodiments.

Referring to fig. 1A to 3, fig. 1A is a schematic diagram of an ultrasonic probe 100 according to an embodiment of the utility model, fig. 1B is a schematic diagram of the ultrasonic probe 100 of fig. 1A detecting a subject 10, fig. 2 is an exploded view of the ultrasonic probe 100 of fig. 1A, and fig. 3 is a schematic diagram of a connector 110 of fig. 1A.

As shown in fig. 1A and 2, the ultrasonic probe 100 includes a connector 110, an ultrasonic transducer assembly 120, and an electrical signal connector 130. The ultrasonic transducer assembly 120 has a sensing face 120e and a connecting side 120c. The connection side 120c and the sensing side 120E are two adjacent sides of the ultrasonic transducer assembly 120, wherein the sensing side 120E is configured to transmit an ultrasonic transmission signal E1 and correspondingly receive an ultrasonic reflection signal R1. The electrical signal connector 130 has a first end portion 131 and a second end portion 132, wherein the first end portion 131 is connected to the connector 110, and the second end portion 132 is connected to the connection side 120c of the ultrasonic transducer assembly 120 along a first connection direction D1.

As shown in fig. 1B, the ultrasonic detector 100 may face or be closely attached to the subject 10 on the sensing surface 120e of the ultrasonic transducer assembly 120 to detect the tissue condition on or in the subject. When the sensing surface 120e faces or is closely attached to the subject 10, a rubberized fabric (not shown) may be used to fix the relative positions of the ultrasonic transducer assembly 120 and the subject 10. For example, with adhesive tape, across the opposite face 120b of the ultrasound transducer assembly 120 and adhered to the subject 10. Since the connecting side 120c and the sensing surface 120e are respectively adjacent two surfaces of the ultrasonic transducer assembly 120, the adhesive tape can cross the opposite surface 120b of the ultrasonic transducer assembly 120 without interfering with the electric signal connector 130, so that the ultrasonic transducer assembly 120 is easily fixed on the object 10 (if the electric signal connector 130 is connected to the opposite surface 120b, the adhesive tape can interfere with the electric signal connector 130, which prevents the adhesive tape from fixing the ultrasonic transducer assembly 120 on the object 10), so that the user does not need to hold the ultrasonic detector 10 continuously, which increases the convenience of operating the ultrasonic detector 10. In addition, since the connecting side 120c and the sensing surface 120e are respectively adjacent two surfaces of the ultrasonic transducer assembly 120, when the sensing surface 120e faces or is closely attached to the object 10, the electric signal connector 130 can extend along the surface 10s of the object 10 without being folded back (if the electric signal connector 130 is connected to the opposite surface 120b of the sensing surface 120e, the electric signal connector 130 must be folded back to extend along the surface 10s of the object 10, but the folding back easily causes the electric signal connector 130 to be damaged, and the folding back also causes the ultrasonic transducer assembly 120 to be subjected to a turning moment, so that the ultrasonic transducer assembly 120 is difficult to be firmly fixed on the object 10).

The subject 10 is, for example, a living body (e.g., a human body or an animal) such as human skin, but may be a non-living body such as an industrial product. In the present embodiment, the electrical signal connector 130 is flexible and/or elongated, so that it is convenient to dispose (e.g., store, fix, paste, etc.) the ultrasonic probe 100 when detecting the subject 10. In one embodiment, the electrical signal connector 130 is, for example, a flexible circuit board, but the utility model is not limited thereto.

As shown in fig. 1A and 2, the ultrasonic probe 100 further includes a first connection port 140A and a second connection port 140B. The first connection port 140A is disposed on the ultrasonic transducer assembly 120. The second connection port 140B is disposed at the second end portion 132 of the electrical signal connector 130 and is used to connect with the first connection port 140A. The first connection port 140A and the second connection port 140B are detachably connected, so that the ultrasonic transducer assembly 120 and the electrical signal connector 130 are detachable. In another embodiment, the first connection port 140A and the second connection port 140B are non-detachably connected (e.g., welded) such that the ultrasonic transducer assembly 120 and the electrical signal connector 130 are non-detachable. In addition, one of the first connection port 140A and the second connection port 140B is, for example, a male connector, and the other of the first connection port 140A and the second connection port 140B is, for example, a female connector.

As shown in fig. 2, the ultrasonic transducer assembly 120 has a recess 120r, the recess 120r extending inwardly from the connection side 120c. The first connection port 140A is disposed in the recess 120r and exposed from the recess 120r to connect with the corresponding connection port. In another embodiment, the first connection port 140A may be configured with the connection side 120c and protrude opposite to the connection side 120c.

As shown in fig. 1A and 2, the ultrasonic probe 100 further includes a third connection port 140C and a fourth connection port 140D. The third port 140C is disposed on the connector 110. The fourth connection port 140D is disposed at the first end portion 131 of the electrical signal connector 130 and is used for connecting with the third connection port 140C. The third port 140C and the fourth port 140D are detachably connected to each other, so that the connector 110 and the electrical signal connector 130 are detachable. In another embodiment, the third port 140C and the fourth port 140D are non-detachably connected (e.g., welded) such that the connector 110 and the electrical signal connector 130 are non-detachable. In addition, one of the third port 140C and the fourth port 140D is, for example, a male connector, and the other of the third port 140C and the fourth port 140D is, for example, a female connector.

As shown in fig. 3, the connecting member 110 is made of plastic, metal, or the like. The connector 110 has low flexibility and high rigidity compared to the electrical signal connector 130. The connecting member 110 has an end face 110s and a groove 110r1, the groove 110r1 extending inward from the end face 110 s. The third connection port 140C is disposed in the recess 110r1 and exposed from the recess 110r1 to connect with the corresponding connection port. In another embodiment, the third connection port 140C may be disposed at the end face 110s and protrude opposite to the end face 110 s.

As shown in fig. 1A-2, in the present embodiment, the ultrasonic transducer assembly 120 is connected to the connector 110 through the electrical signal connector 130, but this is not a limitation of the present embodiment.

In another embodiment, the ultrasonic transducer assembly 120 and the connector 110 may be directly connected. In this example, referring to fig. 2, the third connection port 140C disposed on the connector 110 and the first connection port 140A disposed on the ultrasonic transducer assembly 120 may be directly connected, one of the first connection port 140A and the third connection port 140C is a male connector, the other of the first connection port 140A and the third connection port 140C is a female connector, or the ultrasonic transducer assembly 120 and the connector 110 may be temporarily connected by a clamping technique. For example, the ultrasonic transducer assembly 120 includes a first engaging portion (not shown) formed on the connecting side 120c, and the connecting member 110 includes a second engaging portion (not shown) formed on the end surface 110s (the end surface 110s is shown in fig. 3), and the first engaging portion and the second engaging portion can be temporarily engaged to temporarily fix the relative position between the ultrasonic transducer assembly 120 and the connecting member 110.

In another embodiment, the connector 110 may be connected to different surfaces of the ultrasonic transducer assembly 120. For example, referring to fig. 1A and 2, the ultrasonic transducer assembly 120 further includes an opposite surface 120b, and the opposite surface 120b and the sensing surface 120e are opposite surfaces of the ultrasonic transducer assembly 120, respectively. The connection member 110 may be selectively connected to the opposite surface 120b along the first connection direction D1. In this example, the ultrasonic transducer assembly 120 and the connector 110 may be temporarily connected using a snap-fit technique. For example, the ultrasonic transducer assembly 120 includes a third engaging portion (not shown) formed on the opposite surface 120b, and the connecting member 110 includes a fourth engaging portion (not shown) formed on the end surface 110s, where the third engaging portion and the fourth engaging portion can be temporarily engaged to temporarily fix the relative position between the ultrasonic transducer assembly 120 and the connecting member 110. In another embodiment, the connecting member 110 may replace the fourth engaging portion with the second engaging portion, and the second engaging portion and the third engaging portion (the third engaging portion and the first engaging portion have the same structure) may be temporarily engaged to temporarily fix the relative position between the ultrasonic transducer assembly 120 and the connecting member 110.

As shown in fig. 1A, the ultrasonic transducer assembly 120 has a plurality of adjacent sides 120s, wherein the adjacent sides 120s are adjacent to the sensing surface 120e and extend between the sensing surface 120e and the opposite surface 120b. The connecting side 120c is an adjacent side having a relatively long length. In other words, the electrical signal connector 130 is connected to a relatively long adjacent side of the plurality of adjacent sides of the ultrasonic transducer assembly 120 along the first connection direction D1. In another embodiment, the connecting side 120c is an adjacent side having a relatively short length. In other words, the electrical signal connector 130 is connected to a relatively short adjacent side of the plurality of adjacent sides of the ultrasonic transducer assembly 120 along the first connection direction D1, such as the adjacent side 120s1 (in this case, the connecting side 120c is the adjacent side 120s 1). In addition, the sensing surface 120e may be a one-dimensional array, a two-dimensional matrix, a concave surface or a convex surface, and the embodiment of the utility model is not limited thereto.

As shown in fig. 3, the connector 110 may further have a receiving slot 110r2, and the receiving slot 110r2 is configured to receive the electrical signal connector 130. In detail, in the case where the ultrasonic transducer assembly 120 is directly connected to the connector 110, the electric signal connector 130 can be received in the receiving slot 110r2 of the connector 110, so that the connection between the ultrasonic transducer assembly 120 and the connector 110 is not affected and the electric signal connector 130 can be moved along with the ultrasonic detector 100, thereby increasing portability of the electric signal connector 130. In the present embodiment, the electrical signal connector 130 is a flexible circuit board, which has flexibility or pliability, so that it can be deformed to be plugged into the receiving slot 110r 2. In the case where the third port 140C and the fourth port 140D are non-detachably connected (e.g., fixedly connected, such as welded), the electric signal connector 130 may also be directly received in the receiving slot 110r2 of the connector 110, and then the ultrasonic transducer assembly 120 is temporarily connected to the connector 110 by using a clamping technique.

Referring to FIG. 4, a cross-sectional view of the ultrasonic transducer assembly 120 of FIG. 2 along the direction 4-4' is shown. The ultrasonic transducer assembly 120 includes a housing 121, a piezoelectric material layer (Piezoelectric layer) 122, a matching layer (matching layer) 123, a backing layer (backing layer) 124, and an Acoustic lens (Acoustic lens) 125. The piezoelectric material layer 122 and the back layer 124 are disposed in the case 121. The piezoelectric material layer 122 is disposed between the matching layer 123 and the back layer 124. The acoustic lens 125 is disposed on the matching layer 123 and is the outermost optical element of the ultrasonic transducer assembly 120. In one embodiment, the thickness T1 of the back layer 124 may be between 0.2 mm and 10 mm. The thickness T1 of the back layer 124 of the embodiment of the present utility model is thinner than the thickness of the back layer of the conventional ultrasonic transducer assembly, so that the thickness T2 between the sensing surface 120e and the opposite surface 120b can be thinned.

Referring to fig. 5, a schematic diagram of an ultrasonic probe 200 according to another embodiment of the utility model is shown. The ultrasonic probe 200 includes a connector 110, an ultrasonic transducer assembly 120, and an electrical signal connector 230. The ultrasonic probe 200 of the present embodiment includes technical features similar to or identical to those of the ultrasonic probe 100, except that the structure of the electrical signal connector 230 of the ultrasonic probe 200 is different from that of the electrical signal connector 130.

As shown in fig. 5, the electrical signal connector 230 includes an adapter plate 231 and a circuit board 232. The interposer 231 is used for connecting the connection side 120c of the ultrasonic transducer assembly 120 along the first connection direction D1. The circuit board 232 is connected to the interposer 231 in the second connection direction D2. The circuit board 232 may have the same or similar structure as the electrical signal connector 130 described above, or the circuit board 232 may be an electrical signal connector 130. The first connection direction D1 is non-parallel to the second connection direction D2. Thus, the direction of the circuit board 232 (e.g., the direction of the outgoing line from the ultrasonic transducer assembly 120) can be changed by the adapter plate 231, so that the moment of the ultrasonic transducer assembly 120 being turned over by the electric signal connector 230 can be reduced. In one embodiment, the first connection direction D1 is substantially perpendicular to the second connection direction D2, or both form an acute angle or an obtuse angle, wherein the acute angle is, for example, between 10 degrees (including 10 degrees) and 90 degrees (excluding 90 degrees), and the acute angle is, for example, between 90 degrees (excluding 90 degrees) and 180 degrees (excluding 180 degrees).

The ultrasonic transducer assembly 120, the adapter plate 231, and the circuit board 232 are both detachably connected or non-detachably connected, as further illustrated below.

As shown in FIG. 5, the ultrasonic probe 200 further includes a fifth port 240A and a sixth port 240B. The fifth port 240A and the sixth port 240B are disposed on the adapter 231. The fifth port 240A is configured to connect with the first port 140A of the ultrasonic transducer assembly 120. The first connection port 140A is detachably connected to the fifth connection port 240A, so that the ultrasonic transducer assembly 120 and the adapter plate 231 are detachable. In another embodiment, the first connection port 140A and the fifth connection port 240A are non-detachably connected (e.g., fixedly connected) such that the ultrasonic transducer assembly 120 and the adapter plate 231 are non-detachable. In addition, in the present embodiment, the first connection port 140A is, for example, one of the male connector and the female connector, and the fifth connection port 240A is, for example, the other of the male connector and the female connector.

As shown in fig. 5, the sixth connection port 240B is configured to connect with the second connection port 140B disposed on the circuit board 232. The sixth connection port 240B is detachably connected to the second connection port 140B, so that the circuit board 232 and the adapter plate 231 are detachable. In another embodiment, the second connection port 140B and the sixth connection port 240B are non-detachably connected (fixedly connected), such that the circuit board 232 and the interposer 231 are non-detachable. In addition, in the present embodiment, the sixth connection port 240B is, for example, one of the male connector and the female connector, and the second connection port 140B is, for example, the other of the male connector and the female connector.

In summary, an embodiment of the present utility model provides an ultrasonic probe, in which an electrical signal connector is connected to a side surface adjacent to a sensing surface. Thus, when the sensing surface faces or is closely attached to the tested body, the electric signal connecting piece can extend along the surface of the tested body in a proper way without being folded back. Because the electric signal connecting piece is connected to the side surface adjacent to the sensing surface, the adhesive tape can cross the opposite surface of the ultrasonic transducer assembly and can not interfere with the electric signal connecting piece, so that the ultrasonic transducer assembly is easily fixed on a tested body, a user does not need to continuously hold the ultrasonic detector, and the convenience of operating the ultrasonic detector is improved. In one embodiment, the electrical signal connector is, for example, a flexible circuit board, so that handling (e.g., storage, fixing, adhering, etc.) is facilitated, and thus the ultrasonic probe does not need to be held in the hand for detecting the subject.

The utility model has been described with respect to the above-described embodiments, however, the above-described embodiments are merely examples of practicing the utility model.
