Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to an ultrasound detection device and a medical system. Background Technology

[0002] With the advancement of medical technology, ultrasound-assisted interventional therapy is increasingly being used in clinical diagnosis and treatment. An ultrasound probe is inserted into the cavity being examined to explore the lesion site, and the doctor then uses a biopsy needle or other instruments to take samples or perform other treatments on the lesion site.

[0003] Because the ultrasound probe is located inside the cavity being examined, and the ultrasound scan produces a tomographic image of that cavity, it is difficult for doctors to pinpoint the exact location of the probe within the cavity, and consequently, the location of any lesion. Therefore, doctors sometimes need to press on the outer wall of the cavity to locate the probe. However, this method of locating the probe is neither accurate nor fast, and may cause additional harm to the patient. Summary of the Invention

[0004] To at least partially address the problems existing in the prior art, according to one aspect of the present invention, an ultrasonic testing device is provided. The ultrasonic testing device includes an insertion end inserted into a cavity to be tested along an insertion direction. An optical component and an ultrasonic component are disposed within the insertion end. The ultrasonic component transmits and receives ultrasonic signals to form an ultrasonic imaging area. Light emitted from the optical component passes through the ultrasonic imaging area and penetrates the cavity to form a visible optical marking area on its outer wall surface.

[0005] The ultrasound detection device provided by this invention has an insertion end equipped with an optical component and an ultrasound component. Light emitted from the optical component passes through the ultrasound imaging area and penetrates the examined cavity, forming a visible optical marker area on its outer wall. After determining the specific location of the optical marker area, the ultrasound imaging area can be located, thereby pinpointing the exact location of the lesion area within the examined cavity, and also locating the insertion end within the examined cavity. When this ultrasound detection device is used for ultrasound-assisted interventional therapy, the physician can observe the outer wall of the examined cavity and, by locating the visible optical marker area on the outer wall, infer the location of the insertion end of the ultrasound detection device and the lesion area. Using this ultrasound detection device, physicians can more conveniently and non-invasively locate the insertion end and the lesion area, and the location can be more precise.

[0006] For example, the ultrasonic component includes a transducer whose ultrasonic signal emission direction is toward the side of the insertion direction.

[0007] For example, the optical component includes a mirror, through which light rays emitted from the optical component are directed to pass through the ultrasound imaging area.

[0008] For example, the reflector includes at least one of a reflecting prism and a reflecting plane mirror.

[0009] For example, the optical component includes a focusing element.

[0010] For example, the focusing element includes at least one of a self-focusing lens and a focusing mirror.

[0011] For example, the ultrasonic testing device includes a probe and a light source. The probe is provided with an optical fiber that guides the light emitted from the light source to the insertion end. The light power of the light source is set such that the light emitted from the optical component penetrates the cavity under test and forms a visible optical marking area on its outer wall surface.

[0012] For example, the optical component includes a light-emitting element, the light power of which is set such that light emitted from the optical component penetrates the cavity under test and forms a visible optical marking area on its outer wall surface.

[0013] According to another aspect of the present invention, a medical system is provided, the medical system including a display device and an ultrasound detection device as described above, the display device being communicatively connected to the ultrasound detection device for displaying an ultrasound image formed by ultrasound signals acquired by the ultrasound detection device.

[0014] For example, the medical system also includes a control device that is communicatively connected to the ultrasound detection device for controlling the light emitted from the optical components.

[0015] For example, the control device controls the light emitted by the optical components based on features identified from the ultrasound image.

[0016] A series of simplified concepts are introduced in the description of the invention, which will be further explained in detail in the detailed description section. This description is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0024] In the following description, numerous details are provided to enable a thorough understanding of the invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the invention, and that the invention can be practiced without one or more of these details. Furthermore, to avoid obscuring the invention, some technical features well-known in the art have not been described in detail.

[0025] According to one aspect of the present invention, an ultrasound detection device is provided. The ultrasound detection device can be applied to any suitable system, including but not limited to medical systems. Therefore, according to another aspect of the present invention, a medical system is provided. The medical system may include an endoscope and any of the ultrasound detection devices described below.

[0026] See also Figures 1 to 3 The ultrasonic testing device may include an insertion end 100 that is inserted into the cavity 200 being tested along the insertion direction. An optical component 110 and an ultrasonic component 120 may be disposed within the insertion end 100.

[0027] The cavity 200 being examined can be a blood vessel or esophagus, or it can be an abdominal cavity, gallbladder, etc. The size and shape of the insertion end 100 can be adapted to the characteristics of the cavity 200 being examined, or it can be set to be applicable to various cavities 200 being examined simultaneously. The cavity 200 being examined has a cavity wall 210, which has an outer wall surface 212 and an inner wall surface 211.

[0028] The ultrasonic component 120 transmits and receives ultrasonic signals to form an ultrasonic imaging region C. Light rays emitted from the optical component 110 pass through the ultrasonic imaging region C and penetrate the tested cavity 200, forming a visible optical marking region on its outer wall 212. The light rays can penetrate from the inner wall 211 to the outer wall 212 of the tested cavity 200. This requires the light power to meet a set threshold to penetrate the cavity wall 210 of the tested cavity 200. Different light powers can be used to irradiate different tested cavities 200, or a light power suitable for all types of tested cavities 200 can be set. The optical marking region can be manifested as a visible light spot formed on the outer wall 212 of the tested cavity 200. Of course, the optical marking region can also be manifested in any suitable form. It is understood that the optical marking region formed on the tested cavity 200 can be located within the ultrasonic imaging region C. The positions and light emission angles of the optical component 110 and the ultrasonic component 120, as well as the ultrasonic signal emission angle, can be adapted to ensure that the optical marking area formed on the cavity under test 200 is located within the ultrasonic imaging area C. When the insertion end 100 of the ultrasonic testing device rotates or moves within the cavity under test 200, the optical component 110 and the ultrasonic component 120 within the insertion end 100 can rotate or move synchronously, thereby maintaining the optical marking area formed on the cavity under test 200 within the ultrasonic imaging area C.

[0029] When such an ultrasound detection device is applied to a medical system, the medical system may include an endoscope. The endoscope can be used to observe a visible light spot outside the cavity 200 being examined, in order to locate the ultrasound detection device inside the cavity 200. The endoscope can be a laparoscope or any other suitable type. For a laparoscope, it can be inserted through an access channel created by a small incision. The endoscopic images acquired by the laparoscope are used to locate the visible light spot on the outer wall surface 212 of the cavity 200 being examined, and the insertion end 100 of the ultrasound detection device inside the cavity 200 can be located by the position of the visible light spot on the outer wall surface 212. Furthermore, a suitable medical instrument can be inserted through the endoscope's channel to treat the visible light spot location, which helps the inserted medical instrument quickly and accurately find the treatment area. If the inserted medical instrument needs to pass through the outer wall of the cavity 200 being examined, the ultrasound image formed by the ultrasound imaging area C can be used simultaneously to more accurately guide the treatment process in real time.

[0030] The ultrasound detection device provided by this invention has an optical component 110 and an ultrasound component 120 disposed within the insertion end 100. Light emitted from the optical component 110 passes through the ultrasound imaging area C and penetrates the examined cavity 200, forming a visible optical marker area on its outer wall surface 212. After determining the specific location of the optical marker area, the ultrasound imaging area C can be positioned, thereby determining the specific location of the lesion area within the examined cavity 200 and also positioning the insertion end 100 within the examined cavity 200. When this ultrasound detection device is used for ultrasound-assisted interventional therapy, the physician can observe the outer wall surface 212 of the examined cavity 200 and, by locating the visible optical marker area on the outer wall surface 212, infer the location of the insertion end 100 and the lesion area. Using this ultrasound detection device, the physician can more conveniently and non-invasively locate the insertion end 100 and the lesion area, and the positioning can be more precise.

[0031] In one embodiment of the present invention, the light emitted from the optical component 110 and the ultrasonic signal emitted from the ultrasonic component 120 can be oriented in the same direction. Specifically, the light emitted from the optical component 110 and the ultrasonic signal emitted from the ultrasonic component 120 can be coaxial, and the light can penetrate the tested cavity 200 to form a visible optical marking area on its outer wall surface 212, and the optical marking area is located within the ultrasonic imaging area C. Alternatively, the light emitted from the optical component 110 and the ultrasonic signal emitted from the ultrasonic component 120 can be non-coaxial, and the light can penetrate the tested cavity 200 to form a visible optical marking area on its outer wall surface 212, and the ultrasonic signal can form an ultrasonic imaging area C on the tested cavity 200, and the optical marking area can be located within the ultrasonic imaging area C. It can be understood that the light and the ultrasonic signal intersect on the tested cavity 200. Thus, by observing the optically marked area on the outer wall surface 212 of the cavity under examination 200, it is easy to infer the specific location of the ultrasound imaging area C and the detected lesion area from the outside of the cavity under examination 200, thereby facilitating surgical treatment of the lesion area. During the assembly process, the assembly precision requirements for the optical component 110 are relatively low. As long as light can pass through the ultrasound imaging area C and form a visible optically marked area on the outer wall surface 212 of the cavity under examination 200, the lesion area on the cavity wall 210 of the cavity under examination 200 can be identified, facilitating the insertion of treatment instruments, such as biopsy needles or other suitable treatment instruments, and then combined with real-time ultrasound imaging guidance for puncture and other operations.

[0032] In one embodiment of the present invention, the ultrasonic component 120 may include a transducer. The ultrasonic signal emission direction of the transducer may be towards the side of the insertion direction. Specifically, the insertion end 100 may be a tubular structure. The ultrasonic signal of the transducer may pass through the side wall of the insertion end 100. Understandably, the light from the optical component 110 may also pass through the side wall of the insertion end 100 and irradiate the cavity wall 210 of the cavity under test 200. In this way, it is ensured that the light emitted by the optical component 110 and the ultrasonic signal emitted by the ultrasonic component 120 are oriented in the same direction. The transducer's transceiver surface faces at least partially the side wall of the insertion end 100. The transducer may be elongated, and the length direction of the elongated transducer may be consistent with the insertion direction. In this way, a larger transducer can be installed in a smaller diameter insertion end 100, and the assembly accuracy requirement of the transducer can be lower, without requiring absolute precision in the installation angle of the transducer, thereby reducing the assembly difficulty.

[0033] In one embodiment of the present invention, see [reference] Figure 2 and Figure 3 The optical component 110 may include a reflector 113. Light rays emitted from the optical component 110 are directed by the reflector 113 to pass through the ultrasonic imaging region C. The reflector 113 facilitates adjustment of the light emission direction during assembly, making it suitable for scenarios where the emission direction is not easily adjusted directly. This allows the optical marking area formed on the inspected cavity 200 to be located within the ultrasonic imaging region C.

[0034] In one embodiment of the present invention, the reflector 113 may include at least one of a reflecting prism and a reflecting plane mirror. Understandably, a reflecting prism may be disposed within the insertion end 100. A reflecting prism provides better light reflection, and when adjusting the light emission direction using a reflecting prism, it is easier to ensure that the optical marking area formed on the tested cavity 200 is located within the ultrasonic imaging area C. A reflecting plane mirror may also be disposed within the insertion end 100. A reflecting plane mirror has a simpler structure, and when adjusting the light emission direction using a reflecting plane mirror, the overall structure of the ultrasonic testing device can be simpler, and the cost can be lower. Both a reflecting prism and a reflecting plane mirror may be disposed within the insertion end 100 to suit various scenarios. The reflector 113 may also include other arbitrary forms, as long as it ensures that the optical marking area formed on the tested cavity 200 is located within the ultrasonic imaging area C.

[0035] In one embodiment of the present invention, see [reference] Figure 2 and Figure 3The optical component 110 may include a focusing element 112. This facilitates the focusing of light, ultimately forming a light spot on the outer wall surface 212, improving light penetration and thus enhancing the visibility of the optically marked area, thereby improving the accuracy of marking the location of the lesion area. Due to the inclusion of the focusing element 112, the required divergence angle of the light emitted from the optical component 110 can be lowered, allowing for the selection of more types of structural components for generating light in the ultrasound detection device, thus broadening its applicability. Specifically, the focusing element 112 can focus the light emitted from the optical component 110 onto the inner wall surface 211. The focusing element 112 can be positioned at different locations and angles. The light emitted from the optical component 110 can be focused by the focusing element 112, and the focusing element 112 and its upstream light-emitting structural components (such as...) can be adjusted to... Figure 2 The light-emitting element 111 shown or as shown Figure 3 By adjusting the relative positions of the optical fiber 1011 (as shown) and the light emission angle of the structure emitting the light from its upstream component and the angle of the focusing component 112, the light emitted from the optical component 110 can form a focal point G on the inner wall surface 211. This makes the light emitted from the optical component 110 more concentrated on the inner wall surface 211 of the cavity under test 200, making it easier to penetrate the cavity under test 200 and form a visible light spot on the outer wall surface 212. This simplifies the positioning of the insertion end 100 by observing the position of the visible light spot outside the cavity under test 200.

[0036] In one embodiment of the present invention, the focusing element 112 may include at least one of a self-focusing lens and a focusing mirror. Understandably, a self-focusing lens can be provided within the insertion end 100, resulting in a simpler structure, easier implementation, easier installation, and easier assembly and production. A focusing mirror can also be provided within the insertion end 100, which can not only focus the light but also adjust the light emission direction, allowing for a smaller size of the insertion end 100, thus enabling its use in minimally invasive surgery. The insertion end 100 can also include both a self-focusing lens and a focusing mirror to suit a wider range of scenarios. The focusing element 112 can also be a conventional focusing lens, a focusing lens assembly, or any other form. Thus, with proper design, the converged light formed after passing through the focusing element 112 irradiates the ultrasound imaging area C, allowing the converged light to penetrate the examined cavity 200 and form a visible optical marking area on its outer wall surface 212. The brightness per unit area of ​​the light converged by the focusing element 112 is greater than the brightness per unit area of ​​the light before convergence. By increasing the brightness of light per unit area through the light-concentrating element 112, the light is less likely to be diffused by the cavity wall 210 when it passes through the cavity wall 210, thereby enhancing the visibility of the optical marking area.

[0037] For example, the magnification of the focusing element 112 can be greater than 1. The rear working distance of the focusing element 112 with a magnification greater than 1 can be greater than the front working distance. Such a focusing element 112 can be closer to its upstream light-emitting structure, so the overall structure can be more compact, and the overall space occupied by such an ultrasonic testing device can be smaller.

[0038] like Figure 2 and Figure 3 In the illustrated embodiment, the converged light emitted from the focusing element 112 can be reflected by the reflector 113 and then directed toward the ultrasonic imaging region C. In an embodiment not shown, the converged light emitted from the focusing element 112 can be directed toward the ultrasonic imaging region C directly. The light emission direction of the focusing element 112 itself or the bending direction of the optical fiber 1011 can also replace the function of the reflector 113 to adjust the direction of the light emission so that it falls into the ultrasonic imaging region C.

[0039] In one embodiment of the present invention, the ultrasound detection device may include a probe 101 and a light source (not shown in the figure). The probe 101 may be provided with an optical fiber 1011, which guides the light emitted from the light source to the insertion end 100. Understandably, the insertion end 100 may be externally connected to a light source via the optical fiber 1011. The optical power of the light source may be set such that the light emitted from the optical component 110 penetrates the examined cavity 200 and forms a visible optical marking area on its outer wall surface 212. Thus, since the insertion end 100 uses an external light source, the size of the insertion end 100 can be smaller, thereby enabling its use in minimally invasive surgery or for detecting small examined cavities 200. In this embodiment, the external light source can be configured more flexibly, and its optical power or other parameters (e.g., color) can be adjusted over a wider range to suit the actual conditions of the examined cavity 200.

[0040] like Figure 3In the illustrated embodiment, the optical component 110 may include a focusing element 112 and a reflector 113. An optical fiber 1011 guides the light emitted from the light source to the insertion end 100. One end of the optical fiber 1011 is connected to the light source, and the other end is close to the focusing element 112. Because the light emitted from the optical fiber 1011 has a small divergence angle, a smaller focusing element 112 can be used to converge the light emitted from the optical fiber 1011, thereby reducing the size of the insertion end 100 and making it more suitable for minimally invasive surgery. Let ray L1 represent the light path emitted from the optical fiber 1011, ray L2 represent the light path converged by the focusing element 112, and ray L3 represent the light path reflected by the reflector 113. With proper design, the light emitted from the light source is guided by the optical fiber 1011 to the insertion end 100. The light emitted from the optical fiber 1011 near the insertion end 100 first passes through the focusing element 112, and the converged light is reflected by the reflector 113, illuminating the ultrasound imaging area C. This not only allows the light emitted from the optical component 110 to illuminate the ultrasonic imaging area C, ensuring that the optical marking area formed on the tested cavity 200 is located within the ultrasonic imaging area C, but also allows the light emitted from the optical component 110 to form a focal point G on the inner wall surface 211, and makes it easier for the light emitted from the optical component 110 to penetrate the tested cavity 200 to form a visible light spot on the outer wall surface 212. The reflector 113 allows for adjustment of the angle of the light emitted from the optical component 110. Therefore, the light emitted from the optical fiber 1011, after being focused by the focusing element 112, does not need to be aligned with the ultrasonic imaging area C. This allows for more choices in the size, angle, and type of the focusing element 112. Similarly, there are more choices in the size of the light source, the angle of the light exit surface, and the light divergence angle. Thus, such an ultrasonic testing device is easier to implement and has a wider range of applications. In an embodiment not shown, the light emitted from the optical fiber 1011, after being focused by the focusing element 112, can directly illuminate the ultrasonic imaging area C. The light emitted from the optical fiber 1011 can also be directed towards the ultrasound imaging area C by adjusting the emission direction through the reflector 113. It should be noted that this method requires a large optical power.

[0041] In one embodiment of the present invention, the optical component 110 may include a light-emitting element 111. A cable 114 may be electrically connected to the light-emitting element 111, providing power to the light-emitting element 111 via an external power source, such as when the ultrasonic testing device is connected to the host computer, where it is powered by a corresponding port of the host computer; alternatively, power may be supplied to the light-emitting element 111 via wireless power supply or other methods, in which case a device such as a coil for receiving power is required. That is, a light-emitting element 111 for emitting light is provided within the insertion end 100. The optical power of the light-emitting element 111 can be set such that the light emitted from the optical component 110 penetrates the tested cavity 200 and forms a visible optical marking area on its outer wall surface 212. By emitting light through the light-emitting element 111 within the insertion end 100, light loss is reduced, making it easier to ensure that the optical marking area formed on the tested cavity 200 is located within the ultrasonic imaging area C. The light-emitting element 111 may include a light-emitting chip, which may be an LED chip, an LD chip, or any other suitable form.

[0042] like Figure 1 In the illustrated embodiment, the light-emitting element 111 is a light-emitting chip. Let ray L1 represent the light path of the beam emitted by the light-emitting chip. The light-emitting surface of the chip can be aligned with the ultrasonic imaging region C. The light emitted by the chip under the excitation of the electrical signal transmitted via cable 114 can form an optical marking region on the outer wall surface 212, and the optical marking region is located within the ultrasonic imaging region C. Preferably, the light-emitting chip here can be an LD chip. LD chips emit light with a smaller divergence angle and concentrated brightness, making it easier for the emitted light to penetrate the tested cavity 200 and form a visible light spot on the outer wall surface 212.

[0043] like Figure 2In the illustrated embodiment, the optical component 110 may include a light-emitting element 111, a focusing element 112, and a reflector 113. The light-emitting element 111 is a light-emitting chip. Let ray L1 represent the light path of the beam emitted by the light-emitting chip, ray L2 represent the light path of the beam converged by the focusing element 112, and ray L3 represent the light path of the beam reflected by the reflector 113. With proper design, the light-emitting chip emits light when excited by an electrical signal transmitted via cable 114. The emitted light first passes through the focusing element 112, and after convergence, the light is reflected by the reflector 113, illuminating the ultrasonic imaging area C. This not only allows the light emitted from the optical component 110 to illuminate the ultrasonic imaging area C, ensuring that the optical marking area on the tested cavity 200 is located within the ultrasonic imaging area C, but also allows the light emitted from the optical component 110 to form a focal point G on the inner wall surface 211, and makes it easier for the light emitted from the optical component 110 to penetrate the tested cavity 200 to form a visible light spot on the outer wall surface 212. Preferably, the light-emitting chip here can be an LED chip. LED chips emit light with a large divergence angle, resulting in higher brightness and better adaptability to structural space constraints. The LED chip, in conjunction with the focusing element 112, concentrates the light, further enhancing the brightness. The reflector 113 allows adjustment of the angle of the light emitted from the optical component 110. Therefore, the light emitted by the light-emitting chip, after being focused by the focusing element 112, does not need to be aligned with the ultrasonic imaging area C. This allows for more choices in the size, angle, and type of the focusing element 112. Similarly, the size of the light-emitting chip, the angle of the light exit surface, and the light divergence angle can all be more varied. Consequently, such an ultrasonic testing device is easier to implement and has a wider range of applications.

[0044] According to another aspect of the present invention, a medical system is provided. The medical system may include a display device and an ultrasound detection device as described above. The display device may be communicatively connected to the ultrasound detection device for displaying an ultrasound image formed by ultrasound signals acquired by the ultrasound detection device. Thus, by combining the ultrasound image with an optically marked area, the location of a lesion area can be quickly determined outside the examined cavity 200, thereby effectively performing surgical treatment.

[0045] For example, the medical system may also include a control device. The control device may be communicatively connected to the aforementioned ultrasound detection device and used to control the light emitted from the optical component 110. Specifically, in different embodiments, the control device may control the light source or light-emitting element 111 to turn on or off, adjust the light power, adjust the color, etc., to adapt to different examined cavities 200.

[0046] The control device can also be communicatively connected to the ultrasound component 120 to control the ultrasound component 120 to transmit and receive ultrasound signals, thereby realizing the functions of optical detection and ultrasound detection. To display the detection results, the medical system may also include an image processor. Specifically, the ultrasound component 120 can be connected to the control device, under which it can transmit and receive ultrasound signals. For example, the control device may include an ultrasound transmitting module and an ultrasound receiving module. The ultrasound signal transmitted by the ultrasound transmitting module can be transmitted to the observed object via a transducer, thus generating an ultrasound echo. The transducer can receive the ultrasound echo and form an ultrasound echo signal. The ultrasound receiving module can receive the ultrasound echo signal transmitted from the transducer, and then the data can be processed by the image processor and displayed on a display device as an ultrasound image of the observed object. The control device can also control the ultrasound component 120 to adjust the power of the ultrasound signal, etc., to facilitate the detection of different examined cavities 200, thus expanding the application range of the medical system. Users can set or adjust the ultrasound component 120 and the optical component 110 according to the parameters required for different examined cavities 200 through the control device. Of course, the control device can also automatically set or adjust the ultrasonic component 120 and the optical component 110 by recognizing the cavity 200 under test.

[0047] For example, the control device can control the light emitted by the optical component 110 based on features identified from the ultrasound image. For instance, when the location of a lesion or suspected lesion is identified by AI, the control device automatically controls the light emitted by the optical component 110 to be turned on; when no lesion is identified, the control device controls the light emitted by the optical component 110 to be turned off. This avoids the adverse effects on patients or medical staff caused by continuously emitting high-power light.

[0048] Of course, when it is necessary to position the insertion end 100, the light emitted by the optical component 110 can also be manually turned on or off. For example, when a doctor discovers a lesion by observing ultrasound images and wants to treat it with medical instruments, the doctor can manually turn on the light source or light-emitting element 111. The adjustment of light power or color can also be set to manual or automatic. For example, the medical system analyzes the type of human organ or tissue corresponding to the examined cavity 200 through ultrasound images, or sets the required light power or color by the optical imaging mode currently used by the endoscope participating in the diagnosis and treatment. Therefore, the control device can also communicate with the endoscope to manage the ultrasound, endoscope motion control, image display, etc. in the medical system.

[0049] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front", "rear", "up", "down", "left", "right", "horizontal", "vertical", "horizontal", "top", and "bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0050] For ease of description, relative terms such as "above," "over," "on the upper surface of," and "above" are used here to describe the regional positional relationship of one or more components or features shown in the figures to other components or features. It should be understood that relative terms include not only the orientation of the component as depicted in the figure but also different orientations during use or operation. For example, if the components in the figures are inverted as a whole, "above" or "above other components or features" will include cases where the component is "below" or "under" other components or features. Thus, the exemplary term "above" can include both "above" and "below." Furthermore, these components or features may also be positioned at other different angles (e.g., rotated 90 degrees or other angles), and this document intends to include all such cases.

[0051] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of features, steps, operations, parts, components, and / or combinations thereof.

[0052] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in sequences other than those illustrated or described herein.
