Technical Field

[0001] The utility model relates to the technical field of intracavitary ultrasonic equipment, in particular to an ultrasonic probe and an ultrasonic device. Background Art

[0002] At present, endoscopic examination is particularly important for the diagnosis of digestive and respiratory diseases. Endoscopic ultrasound equipment can clearly screen for lesions of various layers of tissue below the digestive tract mucosa, such as tumors and cysts, and can obtain tomographic images of nearby organs such as the mediastinum, pancreas, bile duct and lymph nodes.

[0003] Ultrasonic probes are an important part of endoscopic ultrasound equipment. Since clinical applications are performed in cavities, all ultrasonic probes are catheter-type. The field of view of existing ultrasonic probes is lateral, that is, the ultrasonic transducer is located on the side wall of the catheter. During clinical use, water is filled between the probe and the tissue, and then ultrasonic signals are emitted for inspection.

[0004] However, in actual operation, it is difficult to store water medium after water is injected into the cavity. When water shortage occurs, the only way is to adjust the bending direction or angle of the endoscope to increase the fit with the tissue. It can be seen that the transducer is located on the side wall of the catheter, which makes it difficult to fit the probe and the cavity tissue and inconvenient to use.

[0005] Therefore, the prior art still needs to be improved and developed. Utility Model Content

[0006] In view of the above-mentioned deficiencies of the prior art, the purpose of the present utility model is to provide an ultrasonic probe and an ultrasonic device, aiming to solve the problem that the existing ultrasonic probe has a transducer disposed on the side wall of a catheter, which is difficult to fit with tissues and inconvenient to use.

[0030] In order to enable those skilled in the art to better understand the solution of the utility model, the following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1 and Figure 2In one embodiment of the utility model application, an ultrasonic probe is disclosed, which includes a plug 10, a catheter 20, a transducer component 30 and a signal line (not shown in the drawings), wherein the signal line is located in the catheter 20, one end of the catheter 20 is connected to the plug 10, and the other end is provided with an assembly surface 21; the assembly surface 21 is provided with the transducer component 30, and the transducer component 30 is electrically connected to the plug 10 through the signal line.

[0032] The ultrasound probe disclosed in this embodiment is applied to the inspection or surgical process in the cavity. Specifically, the ultrasound probe can be carried in the instrument channel of the endoscope, inserted into the cavity through the endoscope, extended from the instrument channel of the endoscope, moved along the narrow cavity to the target position, and then attached to the wall of the cavity for inspection.

[0033] When in use, the plug 10 is plugged into the host of the ultrasound system to connect to the ultrasound processing system. The current endoscope device is generally provided with a movable base carrying the host, and the power harness, controller, display screen, data processing equipment and other components are integrated on the host to form an ultrasound processing system, which can be used to control the emission of ultrasound signals, as well as the collection and imaging of ultrasound signals. The existing ultrasound processing system is generally equipped with an adapter. In this embodiment, the plug 10 is plugged into the adapter and encapsulated by a shell to facilitate docking with the host for use and realize electrical adaptation and signal transmission.

[0034] Specifically, a signal line is arranged in the catheter 20 and extends to the end of the catheter 20, namely the assembly surface 21, and is connected to the transducer component 30. The signal of the transducer component 30 is transmitted to the ultrasonic processing system through the signal line to facilitate ultrasonic imaging.

[0035] In this embodiment, the transducer component 30 is arranged on the end face of the catheter 20, so that the ultrasonic signal is transmitted and received in the forward direction of the catheter 20. Compared with the traditional method of transmitting ultrasonic signals in the side direction, it can better fit the cavity surface, thereby increasing the fit with the tissue, and the data obtained when transmitting and receiving ultrasonic signals is more accurate, reducing the dependence on the conductive medium, and even in the case of water shortage in the surrounding environment, accurate ultrasonic signals can be collected, which is convenient for the use of the ultrasonic probe. In addition, the front end field of the catheter 20 is better, with a large viewing angle, and can realize the fan-shaped scanning in the forward direction, forming a fan-shaped ultrasonic slice image, which can increase the inspection range and the working range of the ultrasonic probe.

[0036] Specifically, in this embodiment, the catheter 20 is used to encapsulate the signal line and carry the transducer component 30, and plays the role of waterproof, pressure-resistant and biocompatible. The catheter 20 can be a polyamide catheter 20, a polyurethane catheter 20, a polypropylene catheter 20, etc., which can meet the requirements of softness and biocompatibility, and can be extruded and molded, which is convenient to manufacture.

[0037] like Figure 2 and Figure 3 As shown, as an embodiment of the present application, it is disclosed that the transducer component 30 includes any one of a linear array transducer and a convex array transducer. By using different types of transducers, it is possible to adapt to different working occasions and increase the flexibility of the use of the ultrasonic probe. Specifically, the linear array transducer is to arrange multiple transducer array elements in a straight line direction to form a one-dimensional long strip linear array transducer to increase the scanning range of the transducer component 30; the convex array transducer is to arrange multiple transducer array elements along a curved trajectory to form a convex array transducer with a convex shape as a whole to obtain a wide-angle observation area.

[0038] Specifically, the transducer components 30 are provided with at least two groups, and at least two groups of the transducer components 30 are cross-arranged on the assembly surface 21, and the intersection of any two groups of the transducer components 30 is located at the center point of the assembly surface 21. In this embodiment, the range that the ultrasound probe can detect is increased by setting multiple groups of transducer components 30. Specifically, any two groups of the transducer components 30 are cross-arranged, and ultrasound signals can be emitted in at least two dimensional directions, so that two-dimensional plane imaging in multiple directions can be performed, so that the imaging effect of the ultrasound probe is better, and more imaging information of the ultrasound probe can be obtained, further increasing the inspection range of the ultrasound probe.

[0039] Specifically, as an implementation of this embodiment, the angle between two adjacent groups of transducer components 30 is disclosed to be in the range of 45-90 degrees. If the angle between adjacent transducer components 30 is too small, the overlapping range during detection is large and the use efficiency is low, so the angle between two adjacent transducer components 30 is set to be at least 45 degrees.

[0040] Preferably, Figure 3 As shown, as an implementation of this embodiment, it is disclosed that two groups of transducer components 30 are provided, the angle between the two transducer components 30 is 90 degrees, and they are arranged in a cross shape on the assembly surface 21 for simultaneously emitting ultrasonic signals along the axial direction of the catheter 20.

[0041] In this embodiment, by setting up transducer components 30 arranged in different directions, ultrasonic signals are emitted in multiple directions, and two-dimensional or multi-dimensional scanning can be performed. When the transducer components 30 are arranged in a cross shape, the size of the tissue in the front-back and left-right dimensions can be measured, which is more helpful for discovering and measuring the size of diseased tissues such as tumors. In addition, the transducer components 30 arranged in a cross shape can basically cover the measurement of all dimensions on the two-dimensional plane. For the two-dimensional detection effect, there is no need to set the transducer components 30 in other directions, which improves the use efficiency of the transducer components 30 and simplifies the structure of the transducer components 30.

[0042] For example Figure 2 As shown, as another implementation of this embodiment, it is disclosed that the end of the catheter 20 away from the plug 10 is provided with two arched protrusions 22 arranged in a cross shape, and the top surfaces of the two arched protrusions 22 are combined to form the assembly surface 21; a plurality of the transducer components 30 are divided into two groups and arranged along the axial direction of the two arched protrusions 22.

[0043] In this embodiment, the transducer component 30 is arranged on the top surface of the arched protrusion 22, so that the transducer component 30 is arranged in an orderly manner in the three-dimensional space. The ultrasonic signal emission depths of the transducer component 30 at the center position of the assembly surface 21 and the transducer component 30 at the edge position are different, and the angles are also different. Therefore, when used in combination, the transducer component 30 can realize scanning in two directions and form dual-plane imaging along the directions of two orthogonal sections, so that the pathological condition of the tissue can be more intuitively reflected on the display screen.

[0044] like Figure 4 As shown, as an implementation of this embodiment, a plurality of transducer components 30 are provided, and the array is arranged on the assembly surface 21 to form a two-dimensional rectangular array transducer. By arranging the transducer components 30 in a rectangular array, phase delay is utilized to emit superimposed ultrasonic waves, so as to realize volume imaging and increase the use function of the ultrasonic probe.

[0045] like Figure 5 and Figure 6 As shown, as another implementation of this embodiment, it is disclosed that the transducer component 30 includes at least one group of annular array transducers, and at least one group of the annular array transducers is arranged in concentric circles on the assembly surface. The annular array transducer can perform a circular scanning exploration in the forward direction of the catheter 20, increase the exploration range, and obtain a good inspection effect. The annular array transducer is to arrange multiple transducer array elements in an annular shape, so as to obtain excellent ultrasonic focusing characteristics, which is conducive to improving the penetration characteristics of the transducer component 30 and improving the resolution of the final imaging.

[0046] The transducer component 30 disclosed in this embodiment is annular, and is composed of a plurality of concentric annular units, each of which is composed of a plurality of annular array elements (or fan-shaped array elements), and each annular array element has the same width or angle, so that the uniformity of the transmitted ultrasonic signal can be improved. Of course, this embodiment is only an example of the structural type of the transducer component 30. In the actual production process, the width or angle of each annular array element can also be set differently according to the clinical application scenario and image requirements.

[0047] In addition, the ultrasonic signals between multiple annular array elements are superimposed on each other. By flexibly controlling the signal emission time of each annular array element or part of the annular array elements and combining different ultrasonic waveforms, inspections of different depths and positions can be achieved. The beam can even be deflected to form two-dimensional ultrasonic cross-sections at different angles and three-dimensional ultrasonic images, thereby increasing the functionality of the ultrasonic probe and improving its use value.

[0048] Therefore, from a functional perspective, in this embodiment, a plurality of transducer components 30 are evenly arranged in a ring shape on the assembly surface 21, which is conducive to emitting ultrasonic waves in combination for inspection.

[0049] like Figure 6 As shown, as an implementation of this embodiment, it is disclosed that the assembly surface 21 is an arc-shaped stepped surface. The transducer component 30 disclosed in this embodiment is arranged at the front end of the catheter 20, and a sector scan can be performed by adjusting the ultrasonic signal, but the angle is limited. By setting the assembly surface 21 as an arc-shaped surface, protruding outward, and then the transducer component 30 is arranged in sequence along the bending direction of the assembly surface 21, a plurality of staggered annular array elements are formed. At this time, due to the staggered positions of the transducer components 30, the crosstalk between the annular array elements on adjacent steps will be small. When ultrasonic signals are emitted at the same time, the combined ultrasonic wave has a wider coverage range, a larger depth range that can be explored, a larger range of scanning can be performed, and volume imaging can be achieved, and three-dimensional image observation of the tissue can be performed, further improving the use value of the ultrasonic probe.

[0050] like Figure 7 As shown, as another embodiment of the present application, it is disclosed that the transducer component 30 includes a first transducer array 31 and a second transducer array 32. The first transducer array 31 is arranged around the side of the catheter 20, and is used to transmit ultrasonic signals toward the side of the catheter 20, that is, to transmit ultrasonic signals along the radial direction of the catheter 20; the second transducer array 32 is arranged on the assembly surface 21; the plane where the second transducer array 32 is located coincides with the axial direction of the catheter 20, and is used to transmit ultrasonic signals along the axial direction of the catheter 20.

[0051] The ultrasonic signal of the first transducer array 31 disclosed in this embodiment is directed toward the side of the catheter 20, so that an ultrasonic image of the tissue on the side of the catheter 20 can be obtained. Preferably, the shape of the first transducer array 31 is annular, so that the circumference of the catheter 20 can be scanned 360 degrees without blind spots, and a large range of detection can be performed. The second transducer array 32 is used to transmit ultrasonic signals in the forward direction of the catheter 20. The second transducer array 32 has a structure substantially the same as the aforementioned transducer component 30. Specifically, the shape of the second transducer array 32 can be one-dimensional linear or arched, so as to increase the range that the transducer component 30 can detect. By using the second transducer array 32 in combination with the first transducer array 31, the assembly conditions of the side and front of the front end of the catheter 20 can be covered and scanned, thereby improving the working efficiency of the ultrasonic probe.

[0052] Specifically, as another embodiment of the present application, it is disclosed that the second transducer array 32 includes any one of a linear array transducer, a convex array transducer, and a ring array transducer.

[0053] As another embodiment of the present application, an ultrasound device is also disclosed, which includes any ultrasound probe as described above.

[0054] In summary, the present application discloses an ultrasonic probe, which includes a plug 10, a catheter 20, a transducer component 30 and a signal line, wherein the signal line is located in the catheter 20, one end of the catheter 20 is connected to the plug 10, and the other end is provided with a mounting surface 21; the mounting surface 21 is provided with the transducer component 30, and the transducer component 30 is electrically connected to the plug 10 through the signal line. In this embodiment, the transducer component 30 is arranged on the end surface of the catheter 20, so that the ultrasonic signal is transmitted and received in the forward direction of the catheter 20. Compared with the traditional method of transmitting ultrasonic signals in the side direction, it can better fit the cavity surface, thereby increasing the fit with the tissue, and the data obtained when transmitting and receiving ultrasonic signals is more accurate, reducing the dependence on the ultrasonic signal transmission medium, and can also obtain accurate ultrasonic signals in the absence of water, which is convenient for the use of the ultrasonic probe.
