Description

Technical Field

[0001] The present application relates to the field of medical imaging, and in particular to a coupling agent coating mechanism and an ultrasonic imaging system. Background Art

[0002] Ultrasound imaging is an important method for imaging the interior of a patient's body. Typically, ultrasound imaging systems use an ultrasonic transducer to convert electrical energy into ultrasonic pulses. These pulses are transmitted into the patient's body, generating echo signals. These echo signals are received by the transducer elements and converted into electrical signals. These signals are then processed by specialized equipment to form the desired ultrasound image.

[0003] Ultrasound imaging systems are used in many body parts. For example, full-field breast ultrasound scanners can be used to image breast tissue in one or more planes. During full-field breast ultrasound scans, a coupling agent is typically applied to the patient before the scan.

[0004] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art. Summary of the Invention

[0048] Features described and / or illustrated with respect to one embodiment may be used in the same or similar manner in one or more other embodiments, combined with features in other embodiments, or substituted for features in other embodiments.

[0049] Figure 1 1 shows a perspective view of an ultrasound imaging system 102 according to some embodiments. Figure 1 As shown, the ultrasound imaging system 102 may include a main unit, a display 110, an adjustable arm 106, and a scanning assembly 108. The main unit may include a main frame 104, an ultrasound processor housing 105, and an ultrasound processor within the housing 105. The specific structure of each component will be explained in detail below.

[0050] A body frame 104, an ultrasound processor housing 105 containing an ultrasound processor, a movable and adjustable support arm (e.g., an adjustable arm) 106 including a hinge joint 114, a scanning assembly 108 connected to a first end 120 of the adjustable arm 106 via a ball and socket connector (e.g., a spherical joint) 112, and a display 110 connected to the body frame 104. The display 110 is connected to the body frame 104 at an interface where the adjustable arm 106 enters the body frame 104. By being directly connected to the body frame 104 rather than the adjustable arm 106, the display 110 does not affect the weight of the adjustable arm 106 and the balance mechanism of the adjustable arm 106. In one example, the display 110 is rotatable in horizontal and lateral directions (e.g., rotatable about a central axis of the body frame 104), but is not movable vertically. In an alternative example, the display 110 may also be movable vertically. Although Figure 1 The display 110 is depicted connected to the body frame 104 , but in other examples, the display 110 may be connected to a different component of the imaging system 102 , such as to the ultrasound processor housing 105 , or located remotely from the imaging system 102 .

[0051] In one embodiment, the adjustable arm 106 is configured and adapted so that the compression / scanning assembly 108 (i) is neutrally buoyant in space, or (ii) has a light net downward weight (e.g., 1-2 kg) for breast compression while allowing easy user operation. In an alternative embodiment, the adjustable arm 106 is configured so that the scanning assembly 108 is neutrally buoyant in space during positioning of the scanner on the patient tissue. Then, after positioning the scanning assembly 108, the internal components of the imaging system 102 can be adjusted to apply the desired downward weight for breast compression and increased image quality. In one example, the downward weight (e.g., force) can be in the range of 2-11 kg.

[0052] As described above, the adjustable arm 106 includes a hinge joint 114. The hinge joint 114 divides the adjustable arm 106 into a first arm portion and a second arm portion. The first arm portion is connected to the scanning assembly 108 and the second arm portion is connected to the body frame 104. The hinge joint 114 allows the second arm portion to rotate relative to the second arm portion and the body frame 104. For example, the hinge joint 114 allows the scanning assembly 108 to translate laterally and horizontally but not vertically relative to the second arm portion and the body frame 104. In this way, the scanning assembly 108 can be rotated toward or away from the body frame 104. However, the hinge joint 114 is configured to allow the entire adjustable arm 106 (e.g., the first arm portion and the second arm portion) to move vertically together as one piece (e.g., translate up and down together with the body frame 104).

[0053] The scanning assembly 108 may include a membrane assembly 118 of an at least partially conformable membrane in a substantially taut state for compressing the breast, the membrane assembly 118 having a bottom surface that contacts the breast while the transducer sweeps across its top surface to scan the breast. In one example, the membrane is a taut piece of fabric.

[0054] The membrane assembly 118 may further include an outer frame and a membrane. The membrane is fixedly mounted within the outer frame, which is removably connected to the scanning assembly. During ultrasound imaging by the ultrasound imaging system, one side of the membrane can at least partially contact the ultrasound transducer, while the other side of the membrane can at least partially contact the tissue to be scanned. This arrangement ensures that the ultrasound transducer transmits and receives signals with minimal attenuation and secures the breast to be scanned for easier scanning.

[0055] Optionally, the adjustable arm may include a potentiometer (not shown) to allow for position and orientation sensing of the compression / scanning assembly 108, or other types of position and orientation sensing may be used (e.g., gyroscope, magnetic, optical, radio frequency (RF)). A fully functional ultrasound engine may be provided within the ultrasound processor housing 105 for driving the ultrasound transducer and generating volumetric breast ultrasound data from the scan in conjunction with associated position and orientation information. In some examples, the volumetric scan data may be transmitted to another computer system for further processing using any of a variety of data transmission methods known in the art, or the volumetric scan data may be processed by the ultrasound engine. A general-purpose computer / processor integrated with the ultrasound engine may also be provided for general user interface and system control. The general-purpose computer may be a self-contained, stand-alone unit, or may be remotely controlled, configured, and / or monitored by a remote station connected across a network.

[0056] Figure 2 2 is a block diagram 200 schematically illustrating various system components of the ultrasound imaging system 102. Figure 2 As shown, the ultrasound imaging system 102 includes a scanning assembly 108, a display 110, and a scan processor 210. In one example, the scan processor 210 can be included in the ultrasound processor housing 105 of the imaging system 102. Figure 2 As shown, the scanning component 108, display 110, and scan processor 210 are separate components that communicate with each other; however, in some embodiments, one or more of these components may be integrated (eg, the display and scan processor may be included in a single component).

[0057] exist Figure 2 In the example of FIG, the scanning assembly 108 includes at least a transducer module 220 and a driving device 240. The transducer module 220 includes a transducer array of transducer elements, such as piezoelectric elements, which convert electrical energy into ultrasonic waves and then detect reflected ultrasonic waves.

[0058] Scan component 108 can communicate with scan processor 210 to send raw scan data to the image processor. Scan component 108 can optionally communicate with display 110 to notify the user to reposition the scan component as described above, or to receive information from the user (via user input 244).

[0059] exist Figure 2In the example of FIG. 1 , the scan processor 210 includes an image processor 212, a memory 214, a display output 216, and an ultrasound engine 218. The ultrasound engine 218 can drive the activation of the transducer elements of the transducer module 220 and, in some embodiments, can activate the drive device 240. In addition, the ultrasound engine 218 can receive raw image data (e.g., ultrasound echoes) from the scanning assembly 108. The raw image data can be sent to the image processor 212 and / or a remote processor (e.g., via a network) and processed to form a displayable image of the tissue sample. It should be understood that in some embodiments, the image processor 212 can be included in the ultrasound engine 218.

[0060] exist Figure 2 In an example, information can be transmitted from the ultrasound engine 218 and / or the image processor 212 to a user of the imaging system 102 via a display output 216 of the scan processor 210. In one example, the user of the ultrasound imaging system can include an ultrasound technician, a nurse, or a physician such as a radiologist. For example, a processed image of the scanned tissue can be sent to the display 110 via the display output 216. In another example, information related to the parameters of the scan (such as the progress of the scan) can be sent to the display 110 via the display output 216. The display 110 may include a user interface 242, which is configured to display images or other information to the user. In addition, the user interface 242 can be configured to receive input from the user (such as through a user input unit 244) and send the input to the scan processor 210. In one example, the user input unit 244 can be a touch screen of the display 110. However, other types of user input mechanisms are also possible, such as a mouse, a keyboard, etc.

[0061] The scan processor 210 may further include a memory 214. The memory 214 may include removable and / or permanent devices and may include optical memory, semiconductor memory, and / or magnetic memory, among others. The memory 214 may include volatile, non-volatile, dynamic, static, read / write, read-only, random access, sequential access, and / or additional memory. The memory 214 may store non-transitory instructions executable by a controller or processor (such as the controller or image processor 212) to perform one or more methods or routines. The memory 214 may store raw image data received from the scan assembly 108, processed image data received from the image processor 212 or a remote processor, and / or additional information.

[0062] An embodiment of the present application provides a coupling agent coating mechanism.

[0063] Figure 3 is a schematic diagram of a coupling agent coating mechanism according to an embodiment of the present application. Figure 4This is a schematic diagram of the installation position of the coupling agent coating mechanism of an embodiment of the present application. Figure 5 FIG. 4 is a schematic diagram of the coupling agent coating mechanism viewed from another angle.

[0064] like Figures 3 to 5 As shown, the coupling agent coating mechanism 400 of the present embodiment includes a snap-fit ​​portion 410 that snaps into the scanning probe P and a receiving portion 420 connected to the snap-fit ​​portion 410. The snap-fit ​​portion 410 is provided with a first channel 411. The receiving portion 420 includes a main body 421 for receiving the coupling agent. The interior space of the main body 421 is connected to the first channel 411, and the coupling agent received in the main body 421 flows out along the first channel 411.

[0065] According to the above embodiment, by adding a coupling agent coating mechanism to the scanning probe, automatic application of the coupling agent is achieved, which saves scanning time, avoids waste of coupling agent, improves scanning efficiency, and improves user experience.

[0066] In the above embodiment, there is no restriction on the engagement method between the coupling agent coating mechanism and the scanning probe. It can be achieved by interference fit or by setting an engagement component. Any existing engagement method is applicable to the above structure of the present application.

[0067] With the above structure, the operator only needs to install the coupling agent coating mechanism on the scanning probe to realize automatic coating of the coupling agent, which improves the convenience of coating. In addition, since the coupling agent coating mechanism is engaged with the scanning probe, the coupling agent coating mechanism can be easily removed from the scanning probe when the coupling agent coating mechanism is not needed, thereby improving the convenience of use.

[0068] In some embodiments, as Figure 3 As shown, the scanning probe P is part of the scanning assembly 108. The scanning assembly 108 includes a housing 310, a transducer module 220, and a module receiver 230. The transducer module 220 and the module receiver 230 constitute the aforementioned scanning probe P.

[0069] The housing 310 includes a frame 322 and a handle portion 324, which includes two handles 312. The two handles 312 are opposite each other across the transverse axis of the scanning assembly 108, which is centered on the adjustable arm 106 and is defined relative to the transverse axis 308. The frame 322 is rectangular, and the inner periphery of the frame 322 defines an opening 314. The opening 314 provides space (e.g., a void volume) for translating the module receiver 230 and the transducer module 220 during the scanning process. In another example, the frame 322 can be another shape, such as a square with a square opening 314. In addition, the frame 322 has a thickness defined between the inner periphery and the outer periphery of the frame 322.

[0070] The frame 322 includes four sets of side walls (e.g., a set including inner side walls and outer side walls, the inner side walls defining the opening 314). Specifically, the frame 322 includes a front side wall 326 and a rear side wall 328, the rear side wall 328 being directly connected to the handle portion 324 of the housing 310, and the front side wall 326 being opposite the rear side wall 328 relative to the horizontal axis 306. The frame 322 also includes a right side wall and a left side wall, the respective side walls being opposite each other and both being in a plane defined by the vertical axis 304 and the transverse axis 308.

[0071] The frame 322 of the housing 310 also includes a top side and a bottom side, which are defined relative to the vertical axis 304. The top side faces the adjustable arm 106. The membrane 118 is disposed across the opening 314. More specifically, the membrane 118 is connected to the bottom side of the frame 322. In an example, the membrane 118 is a diaphragm that is held taut across the opening 314. The membrane 118 can be a flexible but non-stretchable material that is thin, waterproof, durable, highly acoustically transparent, chemically resistant, and / or biocompatible. As described above, the bottom surface of the membrane 118 can contact tissue (e.g., a breast) during scanning, and the upper surface of the membrane 118 can at least partially contact the transducer module 220 during scanning. Figure 3 As shown, the membrane 118 is permanently connected to a hard shell clamping portion 119 that surrounds the perimeter of the membrane 118. The clamping portion 119 is connected to the bottom side of the frame 322. In one example, the clamping portion 119 can snap onto a lip on the bottom side of the frame 322 of the housing 310 so that the membrane 118 does not become disconnected during scanning, but is still removably connected to the frame 322. The membrane 118 may not be permanently connected to the hard shell clamping portion 119, and thus the membrane 118 may not be connected to the frame 322 via the hard shell clamping portion 119. Instead, the membrane 118 may be directly and removably connected to the frame 322.

[0072] The handle portion 324 of the housing 310 includes two handles 312 for moving the scanning assembly 108 in space and positioning the scanning assembly 108 on tissue (e.g., on a patient). In alternative embodiments, the housing 310 may not include handles 312. In one example, the handles 312 may be integrally formed with the frame 322 of the housing 310. In another example, the handles 312 and the frame 322 may be formed separately and then mechanically connected together to form the entire housing 310 of the scanning assembly 108.

[0073] exist Figure 3In an example of the embodiment, the scanning assembly 108 can be connected to the adjustable arm 106 via a ball joint 112 (e.g., a ball and socket connector). Specifically, the top dome portion of the handle portion 324 is connected to the ball joint 112. The top of the handle portion 324 includes a depression forming a socket, and the ball of the ball joint 112 fits into the socket. The ball joint 112 can move in multiple directions. For example, the ball joint 112 provides rotational movement of the scanning assembly relative to the adjustable arm 106. The ball joint 112 includes a locking mechanism for locking the ball joint 112 in place, and thereby keeping the scanning assembly 108 stationary relative to the adjustable arm 106. In addition, the ball joint 112 can also be configured to only rotate without moving in multiple directions such as swinging.

[0074] In addition, if Figure 3 As shown, handle 312 of handle portion 324 includes buttons for controlling scanning and adjusting scanning assembly 108. Specifically, the first handle of handle 312 includes a first weight adjustment button 316 and a second weight adjustment button 318. First weight adjustment button 316 can reduce the load applied to scanning assembly 108 from adjustable arm 106. Second weight adjustment button 318 can increase the load applied to scanning assembly 108 from adjustable arm 106. Increasing the load applied to scanning assembly 108 can increase the pressure and amount of compression applied to the tissue on which scanning assembly 108 is placed. In addition, increasing the load applied to the scanning assembly increases the effective weight of the scanning assembly on the tissue to be scanned. In one example, increasing the load can compress a patient's tissue, such as a breast. In this way, varying amounts of pressure (e.g., load) can be applied consistently to scanning assembly 108 during scanning to obtain high-quality images using transducer module 220.

[0075] Prior to a scanning procedure, a user (e.g., an ultrasound technician or physician) may position the scanning assembly 108 on the patient or tissue. Once the scanning assembly 108 is correctly positioned, the user may adjust the weight of the scanning assembly 108 on the patient (e.g., adjust the amount of compression) by using the first weight adjustment button 316 and / or the second weight adjustment button 318. The user may then initiate a scanning procedure using additional controls on the handle portion 324 of the housing 310. For example, Figure 3 As shown, the second handle of the handle 312 includes two additional buttons 330 (not shown separately). The two additional buttons 330 can include a first button for initiating a scan (e.g., once the scanning assembly has been placed on the tissue / patient and the amount of compression has been selected) and a second button for stopping the scan. In one example, once the first button is selected, the ball joint 112 can be locked, thereby stopping the lateral and horizontal movement of the scanning assembly 108.

[0076] The module receiver 230 is positioned within the housing 310. Specifically, the module receiver 230 is mechanically connected to a first end of the housing 310 at a rear sidewall 328 of the frame 322, the first end being closer to the adjustable arm 106 than the second end of the housing 310. The second end of the housing 310 is located at a front sidewall 326 of the frame 322. In one example, the module receiver 230 is connected to the first end via a protrusion of the module receiver 230 that is connected to a motor of the module receiver 230.

[0077] As described above, housing 310 is configured to remain stationary during scanning. In other words, once the weight applied to scanning assembly 108 is adjusted via adjustable arm 106 and ball joint 112 is then locked, housing 310 can remain in a stationary position without translating in the horizontal or lateral directions. However, housing 310 can still translate vertically with the vertical movement of adjustable arm 106.

[0078] In contrast, the module receiver 230 is configured to translate relative to the housing 310 during scanning. Figure 3 As shown, the module receiver 230 translates horizontally relative to the housing 310 along the horizontal axis 306. The motor of the module receiver 230 can slide the module receiver 230 along the upper surface of the first end of the housing 310.

[0079] The transducer module 220 is removably connected to the module receiver 230. Thus, during scanning, the transducer module 220 and the module receiver 230 translate horizontally. During scanning, the transducer module 220 is swept horizontally across the breast under the control of the motor of the module receiver 230 while the contact surface of the transducer module 220 contacts the membrane 118. The transducer module 220 and the module receiver 230 are connected together at the module interface 320. The module receiver 230 has a width that is the same as the width of the transducer module 220. In alternative embodiments, the width of the module receiver can be different from the width of the transducer module 220. In some embodiments, the module interface 320 includes a connector between the transducer module 220 and the module receiver 230, the connector including mechanical and electrical connections.

[0080] The above is an exemplary description of the structure of the scanning component 108 , but the present application is not limited thereto. The coupling agent coating mechanism of the embodiment of the present application can also be engaged with the scanning probe of a scanning component with other structures.

[0081] Figure 6 2 is an exploded schematic diagram of a coupling agent coating mechanism according to an embodiment of the present application.

[0082] like Figure 6As shown, in some embodiments, the receiving portion 420 further includes an extension portion 422 connected to the main body portion 421. The extension portion 422 is provided with a second channel 423 that communicates with the interior space of the main body portion 421. The interior space of the main body portion 421 communicates with the first channel 411 through the second channel 423. Thus, the coupling agent contained in the main body portion 421 can flow into the first channel 411 along the second channel 423 and out.

[0083] In some embodiments, as Figure 6 As shown, the extension portion 422 includes two oppositely disposed extension portions, each of which is provided with the aforementioned second channel 423. As a result, the coupling agent contained within the main body 421 of the receiving portion 420 can flow out from both sides in the direction of movement of the scanning probe P, thereby improving the uniformity and stability of the coupling agent coating.

[0084] In some embodiments, as Figure 6 As shown, the engaging portion 410 has two wall portions 410a and 410b. The space between the two wall portions 410a and 410b is used to accommodate the scanning probe P. That is, after the coupling agent coating mechanism is assembled to the scanning probe P, the two wall portions 410a and 410b are respectively located on both sides of the moving direction of the scanning probe P. Figure 4 As shown, in Figure 4 , the left and right directions are the moving directions of the scanning probe P.

[0085] In some embodiments, as Figure 6 As shown, the first channel 411 is provided as a plurality of channels extending from top to bottom. Figure 6 By providing multiple first channels 411 , the uniformity of coupling agent extrusion can be ensured and the amount used can be reduced as much as possible.

[0086] In the above embodiment, the number of the second channels 423 provided on each extension portion 422 is the same as the number of the first channels 411 provided on the wall portion on the corresponding side. Figure 6 As shown, the number of second channels 423 is the same as the number of first channels 411, both being 8. The number of second channels 423 and first channels 411 provided on the extensions 422 and wall portions on different sides may be the same or different. For example, the number of second channels 423 and first channels 411 on one side may be 8, while the number of second channels 423 and first channels 411 on the other side may be 7. This number may be set as required.

[0087] In the above embodiment, if Figure 6As shown, the width of the first channel 411 can be greater than the width of the second channel 423, and the vertical projection of the second channel 423 falls within the range of the first channel 411. Therefore, when the coupling agent flows out of the main body 421 of the accommodating portion 420, it can first flow out along the second channel 423 with a smaller width, and then flow out along the first channel 411 with a larger width, ensuring smooth outflow of the coupling agent and avoiding blockage during the coupling agent flow.

[0088] The above is just an example, and the present application is not limited thereto. The width of the first channel 411 and the width of the second channel 423 may also be the same and completely connected to each other, which can also ensure the smooth flow of the coupling agent and avoid blockage.

[0089] In the above embodiment, there is no restriction on the connection method between the extension portion 422 and the engaging portion 410 , as long as the second channel 423 and the first channel 411 can be connected, the coupling agent can enter the first channel 411 from the second channel 423 and then flow out from the coupling agent outlet 412 along the first channel 411.

[0090] In some embodiments, as Figure 6 As shown, the extended ends of the two wall portions 410a and 410b each have a coupling agent outlet 412 that communicates with the first channel 411. The through-type coupling agent outlet 412 ensures that even a small amount of coupling agent is evenly dispersed after passing through the first channel 411, thereby achieving a uniform coating effect even when a small amount of coupling agent is used.

[0091] In the above embodiment, if Figure 6 As shown, the coupling agent outlet 412 may be an integral structure formed along the extended ends of the wall portions 410a and 410b. That is, the coupling agent outlet 412 is through-connected. No matter which first channel 411 the coupling agent flows out from, it flows into the coupling agent outlet 412 and is applied to the patient's skin surface from the coupling agent outlet 412. For example, when the scanning probe P is moved in one direction (e.g. Figure 4 As the couplant moves from Figure 4 The coupling agent outlet 412 on the right side of the figure is shown; when the scanning probe P is moved in another direction (eg Figure 4 As the couplant moves from Figure 4 The couplant outlet 412 on the left is shown.

[0092] In some embodiments, as Figure 5 As shown, the curvature of the coupling agent outlet 412 matches the curvature of the extended end of the scanning probe P. Thus, it can be ensured that the coupling agent outlet 412 does not affect the scanning of the patient during the scanning process.

[0093] In some embodiments, as Figure 5 As shown, the height of the coupling agent outlet 412 is higher than the height of the extended end of the scanning probe P. Thus, it can be further ensured that the coupling agent outlet 412 does not affect the scanning of the patient during the scanning process.

[0094] Figure 7 Schematic diagram of a partial structure of the accommodating portion 420 of the coupling agent coating mechanism according to an embodiment of the present application.

[0095] like Figure 6 and Figure 7 As shown, in some embodiments, the housing 420 further includes a pressing portion 424 disposed within the main body 421 and a driving portion 425 for driving the pressing portion 424 to move. Driven by the driving portion 425, the pressing portion 424 moves, thereby squeezing the coupling agent within the main body 421. As a result, the coupling agent contained within the main body 421 can flow into the coupling agent outlet 412 along the second channel 423 and the first channel 411, thereby achieving automatic coating of the coupling agent.

[0096] In some embodiments, as Figure 6 and Figure 7 As shown, the extrusion unit 424 includes a first flip plate 424a and a second flip plate 424b that divide the interior space of the main body 421 into two parts. The driving unit 425 includes a first motor 425a and a second motor 425b. The first motor 425a can drive the first flip plate 424a to move, causing the coupling agent on one side of the first flip plate 424a to flow out. The second motor 425b can drive the second flip plate 424b to move, causing the coupling agent on the other side of the second flip plate 424b to flow out.

[0097] Figure 8 is another schematic diagram of the coupling agent coating mechanism of the embodiment of the present application, showing the coupling agent coating mechanism from the side where the motor is located (eg Figure 6 Left side shown or Figure 6 (right side shown) to observe the coupling agent coating mechanism; Figure 9 This is another schematic diagram of the coupling agent coating mechanism according to an embodiment of the present application, showing the coupling agent coating mechanism from the side where the wall portion 410a or 410b of the engaging portion 410 is located (eg Figure 4 Left side shown or Figure 4 The coupling agent coating mechanism is observed (on the right side shown).

[0098] like Figure 8 and Figure 9 As shown, when the scanning probe moves in the first direction, for example, the scanning probe P moves in the first direction. Figure 4When the left side moves as shown, the first motor 425a drives the first flip plate 424a to rotate, and the coupling agent flows downward along the second channel 423 and the first channel 411 under the pressure of the first flip plate 424a, and then flows out from the coupling agent outlet 412 and is applied to the patient's skin surface; similarly, when the scanning probe moves in the second direction, for example, the scanning probe P moves in the second direction. Figure 4 During the rightward movement shown, second motor 425b drives second flip plate 424b to rotate. The coupling agent, squeezed by second flip plate 424b, flows downward along second channel 423 and first channel 411, then flows out of coupling agent outlet 412 and is applied to the patient's skin. This coupling agent application mechanism thus enables automatic application of coupling agent, saving scanning time, avoiding coupling agent waste, improving scanning efficiency, and enhancing the user experience.

[0099] According to the above embodiment, in some possible implementations, the driving portion 425 drives the pressing portion 424 earlier than the movement of the scanning probe P. For example, Figure 4 As shown, before the scanning probe P moves to the left, the first motor 425a operates. After the couplant flows out of the couplant outlet 412 on the left, the scanning probe P moves to the left and begins operation. When the scanning probe P reaches the far left, the first motor 425a stops, while the second motor 425b starts. After the couplant flows out of the couplant outlet 412 on the right, the scanning probe P moves to the right and begins operation. This enables automatic couplant application during the scanning process. The above is merely an example; in a specific implementation, the drive unit 425 and the scanning probe P can operate simultaneously, depending on specific requirements.

[0100] In some embodiments, as Figures 4 to 6 As shown, the main body 421 is provided with two openings 426. These openings 426 communicate with the two internal spaces divided by the first flip plate 424a and the second flip plate 424b, respectively, for an operator to inject coupling agent into the main body 421. The present application does not impose any restrictions on the location, size, or shape of the openings 426, which depend on specific needs.

[0101] In some embodiments, the main body 421 further includes an electrical connection portion (not shown in the figures), which is connected to the driving portion 425 to transmit electrical energy to the driving portion 425 .

[0102] In the above embodiment, the location of the electrical connection portion is not limited. In one possible implementation, the electrical connection portion includes an electrical receiving terminal, which can be located inside the main body 421 or the engaging portion 410 and cooperates with a power supply terminal of the scanning probe P to receive the aforementioned electrical energy. In another possible implementation, the electrical connection portion includes a cable that receives electrical energy from a source other than the coupling agent application mechanism.

[0103] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0104] In addition, the above description only describes the structure of the coupling agent coating mechanism related to the invention point of this application. In specific implementation, the coupling agent coating mechanism may also include other components to achieve other functions. Figure 6 As shown, the accommodating portion 420 of the coupling agent coating mechanism may further include a cover portion 427 located between the motor 425a / 425b and the main body 421 for covering both ends of the main body 421, and a sealing component 428 for sealing the opening 426, etc.

[0105] As can be seen from the above embodiment, by adding a coupling agent coating mechanism to the scanning probe, automatic application of coupling agent is achieved, saving scanning time, avoiding coupling agent waste, improving scanning efficiency, and enhancing the user experience. Furthermore, with this structure, the operator only needs to attach the coupling agent coating mechanism to the scanning probe to achieve automatic coupling agent application, improving the convenience of application. Furthermore, since the coupling agent coating mechanism is engaged with the scanning probe, it can be easily removed from the scanning probe when no longer needed, further enhancing user convenience.

[0106] The present application also provides an ultrasonic imaging system, which includes a scanning assembly and the coupling agent coating mechanism described in the aforementioned embodiment. The coupling agent coating mechanism has been previously described and will not be further elaborated here.

[0107] In the above embodiment, the scanning assembly may further include a frame, such as Figure 3 The frame 322 shown in FIG. 2 houses the scanning probe (transducer module 220 and module receiver 230) and a drive device 240. The drive device 240 drives the scanning probe to move within the frame 322 to perform ultrasonic scanning. The structure and operation of the scanning assembly have been described in the previous embodiment and will not be repeated here.

[0108] In an embodiment of the present application, the automatically driven scanning assembly and the coupling agent coating mechanism are combined to improve scanning efficiency while improving the user experience, especially compared to traditional handheld ultrasound probes. On the one hand, the upper surfaces of the scanning probe and the transducer in the scanning assembly provide a snap-in site for the coupling agent coating mechanism. However, the side opposite the transducer of the handheld probe usually has a cable or a part that needs to be gripped by the doctor, which makes it difficult to fix the coupling agent coating mechanism. On the other hand, the scanning probe in the scanning assembly is driven by a driving device, so the additional coupling agent coating mechanism will not cause the doctor to feel a decrease in user experience such as increased weight or increased volume. It is difficult for a handheld probe to achieve the above effects.

[0109] The present application has been described above in conjunction with specific embodiments. However, those skilled in the art should understand that these descriptions are merely illustrative and are not intended to limit the scope of protection of the present application.
