Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical equipment, and in particular to a probe device with a filtering structure and echo-guided collection and a use method thereof. Background Art
[0002] Ultrasound detection is a common method in medical technology and can be used in a variety of medical scenarios, such as physical examination, inspection, exploration, gynecological examination, obstetric examination, lesion location detection during surgery, etc. The main principle is to use the different strengths of ultrasound echo signals passing through tissues in different situations to achieve visual white intensity unequal layered imaging of tissues in the body.
[0003] At present, there are certain defects in the ultrasonic probes used for ultrasound. The main reason is that the probes collect sound wave reflections in a messy and unfocused manner, resulting in poor imaging of the probed part, certain overlapping signals and artifacts, which affect the doctor's accurate diagnosis and cannot be used in modern medical scenarios. The chip of the current probe often receives uniform echoes in parallel directions or arc-surface radial directions. However, around many different tissues, punctures, inspections, treatments, etc., echo signals in different directions are required to be more valuable. Bones and air cavities have the greatest impact on echoes. Parallel reception of echoes will make the echoes behind them unacceptable, that is, the image behind them cannot be displayed. (To obtain more images behind them, it is necessary to bypass bones, air, and metal from different directions to receive echoes.) The existing three-dimensional and four-dimensional can only display images within a plane within the graphic, and cannot display the three-dimensional image formed by all tissues in the entire image. Some operations require timely observation of the relationship between all tracheae and tissues (such as: various punctures, surgical guidance, delivery detection, and the relationship between the fetal head and the pelvis). By selecting the echo intensity, different colors and multiple different colors are displayed to better display the relationship between tissue structures and pelvis. At present, orthopedic surgery mainly uses X-rays to observe the relationship between bones. X-rays have radiation effects on the human body, while ultrasound has very little radiation to the human body. The existing observation of bone relationships generally uses two-dimensional ultrasound, which has poor overall observation. The existing three-dimensional ultrasound can only observe the front image, and it is not easy to find the back and narrow tissues (such as: joint cavity, intervertebral space, fracture and tissue in the fracture space). The multi-directional three-dimensional ultrasound can better observe the relationship between bones and bones and whether there are a large number of broken bones, muscles, blood vessels and nerves in the tissues between bones. At the same time, it can display different colors at different depths, which can also be convenient for observation. The existing CT and MRI for examining intervertebral discs are large in size and difficult to move. The examination is basically in a supine position. The patient's intervertebral disc compresses the nerves, which is most serious when standing. CT and MRI cannot be examined, while stereoscopic ultrasound can be examined when the patient is standing, so as to observe the compression of the spinal cord and nerve roots by the intervertebral disc; especially when the patient bends over, it has more diagnostic value.
[0004] To this end, we propose a probe device with a filtering structure and an echo collection guide and a method for using the probe device. Summary of the invention
[0005] The present invention mainly solves the technical problems existing in the above-mentioned prior art and provides a probe device with a filtering structure and echo-guided collection and a use method thereof.
[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a probe device with a filtering structure and an echo guide, comprising a filtering module, an imaging module and a puncture needle, the filtering module comprising a sound wave contact layer, a directional conduction layer is arranged at the bottom of the sound wave contact layer, a sound wave sensor is arranged at the bottom of the directional conduction layer, the bottom of the sound wave sensor is connected to a processor via a transmission line, the bottom of the processor is connected to a converter via a transmission line, the bottom of the converter is connected to a display screen via a transmission line, the display screen displays a stereoscopic image and a two-dimensional image respectively, the stereoscopic image and the two-dimensional image can be on the same screen, can be divided into an upper and lower screen, and at the same time, the two stereoscopic images can form an overall picture, such as: the relationship between the fetus and the pelvis during delivery, the stereoscopic image can display a left external deflection image, a median image, a right positive deflection image and a left positive deflection image.
[0007] Preferably, the present invention does not change the structure of the echo chip, but only adds an ultrasonic guiding structure, which greatly saves costs. At the same time, the technical difficulty is low and easy to complete.
[0008] Preferably, the display screen includes an echo intensity interval selection lever, a display area, a color interval selection lever and a color depth adjustment lever.
[0009] Preferably, the display area adopts a black-bottom display screen.
[0010] Preferably, the display area includes an anechoic area, a low-echoic area, a moderate-echoic area, and a high-echoic area.
[0011] Preferably, the anechoic area is displayed by being colorless and transparent.
[0012] Preferably, the low echo area is displayed in light cyan and green.
[0013] Preferably, the moderate echo area is displayed in white and yellow.
[0014] Preferably, the strong echo area is displayed in orange and red.
[0015] A method for using a probe device with a filter structure and an echo guide, comprising the above-mentioned probe device with a filter structure and an echo guide, specifically comprising the following steps:
[0016] Step 1: placing the probe device at the target site to make the acoustic wave contact layer on the probe device contact the target site;
[0017] Step 2: The directional conduction layer can filter out interfering acoustic oblique waves, ensuring that the ultrasonic echo received by the probe only contains the positive wave of the target acoustic wave, which can filter out clutter to the greatest extent and achieve clear imaging of the probed part;
[0018] Step 3: Based on the existing ultrasonic imaging principle, directly collect the echoes collected by each chip point after filtering at the exploration site, form the signal points of a straight line, and match the angle of the guide to display the data of the angle line of each chip point on the display screen. (The chip point corresponds to the chip point of the display screen, the echo line received by the chip point corresponds to the echo line of the display screen, and the angle of the echo line corresponds to the angle of the display screen, so that the three-dimensional image of the tissue can be reproduced on the display screen), and the three-dimensional image and plane image of the site are formed after processing and displayed on the display;
[0019] Step 4: Adjust, move, and rotate the probe to different angles to adjust the exploration area and position to facilitate the search for the target lesion that needs to be explored;
[0020] Step 5: Based on the existing ultrasound principle, use colors to distinguish echo areas with different intensities to achieve visual distinction between different areas;
[0021] Step 6: Set the filtering function and adjust the threshold to hide the colorless and black areas, that is, remove the non-target areas to further observe the target areas;
[0022] Step 7: Adjust the physical structure of the probe device so that some sound waves are emitted at an angle with other sound waves. This can assist in puncturing the target area with the puncture needle. Because the original sound waves were in the same plane and the echo of the puncture needle could not be obtained, this improved setting can make the puncture needle also generate echoes. By combining the echo position and the detected tissue position with imaging processing, navigation of the puncture needle can be achieved.
[0023] Beneficial Effects
[0024] The present invention provides a probe device with a filtering structure and echo-guided collection and a method of using the same. It has the following beneficial effects:
[0025] (1) The probe device with a filtering structure and echo-guided collection and its use method can filter out interfering sound wave oblique waves by adopting the design of a directional conductive layer, ensuring that the ultrasonic echo received by the probe only has the positive sound wave in the target direction, thereby significantly improving the imaging clarity and accuracy of the probed part, and helping doctors to make accurate diagnoses.
[0026] (2) The probe device with a filtering structure and echo-guided collection and the method of using the same use colors to distinguish echo areas of different intensities, so that the echo intensities of different areas can be clearly visualized on the display, and abnormal signals in the same area can be displayed, further improving the doctor's diagnostic efficiency.
[0027] (3) The probe device with a filtering structure and echo-guided collection and its use method can adjust the threshold to hide non-target areas by setting a screening function, retaining only the target area that needs to be observed and removing image interference from other areas, so that doctors can focus more on the detection of target lesions.
[0028] (4) The probe device with a filtering structure and echo-guided collection and its use method can receive echoes from multiple directions by adjusting the physical structure of the probe device, so that some sound waves are emitted at an angle with other sound waves, and the puncture needle that could not be displayed by the original parallel probe can now be displayed. The puncture needle is used to puncture the target part, realizing the navigation function of the puncture needle, and providing a more accurate and safe auxiliary means for medical surgery.
[0029] (5) The probe device with a filtering structure and echo-guided collection and the method of using the probe device can receive echoes from different directions with the same probe, and can receive echoes from more tissues such as joints, fractures, stones, intestinal cavities, stomachs, etc., which are difficult for frontal echoes to pass through. The tissues that will be tested in the future can be tested now, or more tissues can be tested.
[0030] (6) A probe device with a filtering structure and echo-guided collection, and a method for using the same, can be used for areas that are inconvenient to be probed by ultrasound, and can combine exploration images of the target area from multiple angles to form a three-dimensional image, which is convenient for subsequent diagnosis. For example, during childbirth, a probe can be placed at the xiphoid process and the perineum to obtain upper and lower three-dimensional images of the fetus. After splicing, a graphic of the entire delivery process can be obtained, so that obstetricians can judge the overall condition of the parturient.
[0031] (7) A probe device with a filtering structure and echo-guided collection and a method of using the same. The two-dimensional image generated by the device can display the plane as a dotted line in a three-dimensional figure, so that the operator can better find the target plane. At the same time, through tissue stereoscopic imaging and Doppler blood flow stereoscopic imaging, the three-dimensional conditions of tissues and blood vessels can be determined to determine the disease. At the same time, it can reduce and avoid damage to small and medium-sized blood vessels caused by puncture and surgical operations, reduce puncture bleeding, and ensure the safety of patients.
[0032] (8) A probe device with a filtering structure and echo-guided collection and a method of using the same device. The chip points on the straight line of the probe can receive echoes from tissues in multiple directions, which allows for a wider signal viewing angle. Multiple chip points receive echoes from a point on the same tissue, which can make the target tissue display clearer and more realistic, while also having an enhanced display effect. The device is also provided with an angle adjustment head that can guide the echo direction, making the target image clearer and more realistic. The adjustment device can also adjust the two-dimensional image display angle, which can be set not only to vertical or horizontal, but also to 15°, 30°, 45°, 60°, or multiple directions.
[0033] (9) Existing CT and MRI examinations of intervertebral discs are bulky and difficult to move. The patient is basically in a supine position during the examination. However, the patient's intervertebral disc compresses the nerves, which is most serious when the patient is standing. CT and MRI cannot be used for examination. However, stereoscopic ultrasound can be used when the patient is standing, so as to observe the compression of the intervertebral disc on the spinal cord and nerve roots, including when the patient bends over.
[0034] (10) By adjusting the echo intensity adjustment lever, stereo ultrasound can be used to diagnose fractures and guide orthopedic surgery. BRIEF DESCRIPTION OF THE DRAWINGS

The display area includes anechoic area, low echo area, moderate echo area and strong echo area. The anechoic area is displayed by colorless transparency, the low echo area is displayed by light cyan and green, the moderate echo area is displayed by white and yellow, and the strong echo area is displayed by orange and red. The design of directional conduction layer can filter out interfering sound wave oblique waves, ensuring that the ultrasonic echo received by the probe is only the target sound wave positive wave, thereby significantly improving the imaging clarity of the exploration site and helping doctors to make accurate diagnosis.
[0063] A method for using a probe device with a filtering structure and an echo guide, comprising the above-mentioned probe device with a filtering structure and an echo guide, specifically comprising the following steps: a first step: placing the probe device at a target site to be investigated, so that the sound wave contact layer on the probe device contacts the target site; a second step: filtering the interfering sound wave oblique wave through the directional conduction layer to ensure that the ultrasonic echo received by the probe only has the target sound wave positive wave, and can filter out clutter to the maximum extent, thereby achieving accurate imaging of the investigated site; a third step: based on the existing ultrasonic imaging principle, directly processing the filtered echo of the investigated site to form a three-dimensional image and a plan view of the site, and displaying them on a display; a fourth step: adjusting the filter channel of the directional conduction layer to different angles, To adjust the exploration area and position to facilitate the search for the target lesion that needs to be explored; the fifth step: based on the existing ultrasound principle, use color to distinguish echo areas of different intensities to achieve visual distinction between different areas; the sixth step: set the screening function, adjust the threshold to hide the colorless and black areas, that is, remove the non-target area to further observe the target area; the seventh step: adjust the physical structure of the probe device so that some sound waves are emitted at an angle to other sound waves, and cooperate with the puncture needle to assist in puncturing the target area. Because the original sound waves are in the same plane and the echo of the puncture needle cannot be obtained, this improved setting can make the puncture needle also generate echoes. According to the echo position and the detected tissue position, combined with imaging processing, the navigation of the puncture needle can be achieved.
[0064] Embodiment 2: Based on Embodiment 1, Figure 3-Figure 7As shown, the stereogram can display the left outer deflection image, the median image, the right positive deflection image and the left positive deflection image. The display screen includes an echo intensity range selection lever, a display area, a color range selection lever and a color depth adjustment lever.

The echo-free area is displayed by colorless transparency, the low echo area is displayed by light cyan and green, the moderate echo area is displayed by white and yellow, and the strong echo area is displayed by orange and red. By using colors to distinguish echo areas of different intensities, different areas show obvious visual differences on the display, which further improves the doctor's diagnostic efficiency.
[0065] Embodiment 3: Based on Embodiment 1 and Embodiment 2, Figure 4-Figure 7 As shown, the display screen includes an echo intensity interval selection lever, a display area, a color interval selection lever and a color depth adjustment lever. The display area adopts a black background display screen. The display area includes an echo-free area, a low echo area, a moderate echo area, and a strong echo area. The echo-free area is displayed by colorless transparency, the low echo area is displayed by light cyan and green, the moderate echo area is displayed by white and yellow, and the strong echo area is displayed by orange and red. By setting the filtering function, the threshold can be adjusted to hide the non-target area and only retain the target area that needs to be observed, so that the doctor can focus more on the exploration of the target lesion.

By adjusting the physical structure of the probe device, some sound waves are emitted at an angle to other sound waves, and the puncture needle is used to puncture the target site, thereby realizing the navigation function of the puncture needle, providing a more accurate and safe auxiliary means for medical surgery.
[0067] Embodiment 5: Based on Embodiment 1, Embodiment 2, Embodiment 3 and Embodiment 4, Figure 1-Figure 7 As shown, a method for using a probe device with a filter structure and an echo guide includes the above-mentioned probe device with a filter structure and an echo guide, and specifically includes the following steps:
[0068] Step 1: placing the probe device at the target site to make the acoustic wave contact layer on the probe device contact the target site;
[0069] Step 2: The directional conductive layer can filter out interfering acoustic oblique waves, ensuring that the ultrasonic echo received by the probe contains only the positive wave of the target acoustic wave, which can filter out clutter to the greatest extent and achieve clear imaging of the probed part;
[0070] Step 3: Based on the existing ultrasonic imaging principle, the filtered echoes of the probed part are directly processed to form a three-dimensional image and a plane image of the part, and displayed on the monitor;
[0071] Step 4: Adjust the filter channel of the directional conduction layer to different angles to adjust the detection area and position to facilitate the search for the target lesion to be detected;
[0072] Step 5: Based on the existing B-ultrasound principle, use colors to distinguish echo areas with different intensities to achieve visual distinction between different areas;
[0073] Step 6: Set the filtering function and adjust the threshold to hide the colorless and black areas, that is, remove the non-target areas to further observe the target areas;
[0074] Step 7: Adjust the physical structure of the probe device so that some sound waves are emitted at an angle with other sound waves. This can assist in puncturing the target area with the puncture needle. Because the original sound waves were in the same plane and the echo of the puncture needle could not be obtained, this improved setting can make the puncture needle also generate echoes. By combining the echo position and the detected tissue position with imaging processing, navigation of the puncture needle can be achieved.
[0075] See also Figure 8 The existing ultrasound probes cannot perform midline puncture, but some of our punctures require midline puncture (such as: intraspinal puncture: midline puncture, lateral approach, paralateral approach, among which midline puncture is the most common).
[0076] The reason is:
[0077] (1) Existing probes basically receive sound waves that are perpendicular to the probe surface. The midline approach is also perpendicular to the probe surface. The sound waves do not collide with the puncture needle and cannot form an echo, thus they cannot be detected by the ultrasound probe.
[0078] (2) In this case, we can only choose the lateral entry method, but the lateral entry method only shows a point on the two-dimensional ultrasound, which requires high operational skills to master. Any deviation will damage tissues other than the target.
[0079] Solution:
[0080] (1) The present invention arranges multiple rows of sound wave pressure elements to filter and guide the sound waves, forming the echo into a three-dimensional shape, and the echo can be obtained at any angle, so that it can be displayed on ultrasound;
[0081] (2) The probe is made into a small “h” shape, and midline puncture can be performed;
[0082] (3) Multiple rows of pressure elements are arranged to form a three-dimensional ultrasound display. Therefore, during the puncture process, no matter what angle is used, the puncture is in the plane, which reduces the difficulty of operation and increases the safety of operation.
[0083] See also Fig. 9 , Fig. 9 It is a double-headed, enlarged probe with a concave center. The two ends of the probe are enlarged and the middle is concave.
[0084] The probe chips at both ends are oriented as follows:
[0085] (1) Vertically downward, the tissue directly below the probe can be seen;
[0086] (2) Looking diagonally inward, one can see the internal tissue structure of the middle area.
[0087] The two ends of the vertical puncture probe can receive the echo of the middle tissue and the puncture needle, and can display the signal and relationship between the middle tissue and the puncture needle. (Vertical puncture is possible)
[0088] See also Fig.10 , Fig.10 This is a schematic diagram of the two ends of the concave probe being obliquely inwardly received. Question:
[0089] (1) All planar pressure elements are parallel to the probe surface, so the sound waves received are perpendicular to the probe direction;
[0090] (2) There is no sound wave guide on the surface of the pressure element, and the sound waves are mainly absorbed in the direction of the probe, and the sound waves cannot be absorbed in a directional manner;
[0091] (3) The sound waves sensed by the pressure element are mixed waves. As long as the sound waves can propagate to the pressure element, they will be displayed in the pressure element method.
[0092] (4) The sound waves in front of the ordinary ultrasonic pressure element are not filtered in the echo direction, so the recovery is inaccurate;
[0093] (5) Ordinary probes (including 3D and 4D) emit sound waves vertically, without multi-angle, 3D, or cross-recovery. They cannot display the approach and puncture needle well for spinal puncture. They cannot bypass kidney stones and bubbles well, and the structures behind them cannot be seen.
[0094] See also Fig.11 , Fig.11This is a diagram of the sound wave introduction layer, the micro-decomposition of the sound insulation material, and the sound filtering structure of the sound guiding material. The cylinder in the sound wave introduction layer is a sound guiding column made of a material that is easy to conduct sound (such as rubber material), and the sound guiding column is surrounded by sound insulation material. When the echo hits the sound insulation material, it will bounce back and will not enter the sound guiding column and will not be displayed, thereby filtering out some echoes in non-target directions. When the echo enters the sound guiding column, the echo will enter the sound wave introduction layer along the sound guiding column and be transmitted to the pressure element below. After conversion, it will be displayed on the monitor.
[0095] The sound insulation material is a material containing a large number of microbubbles in the middle (it can be a material composed of tiny bubbles produced by the reaction of rubber and chemical substances, and there are simpler materials, such as fir wood (the lightest type of wood, with many pores in the middle, and drilling holes in the middle to inject sound-conducting materials)).
[0096] When sound collides with the sound insulation material, it will continuously bounce back against the bubbles in the middle. In one case, it will bounce out of the sound insulation material, and in the other case, it will continuously bounce back in each bubble. As the sound continuously bounces back, its ability will continue to decay, and eventually disappear or weaken to the point where the pressure element will no longer sense it.
[0097] When the sound rebounds in the direction of the sound guide, it will directly enter the sound guide material, be transmitted to the pressure element, and be displayed on the display.
[0098] When sound that is not in the sound guiding direction rebounds, the sound will enter the sound guiding material and collide with the wall of the sound guiding column. There is vertical sound guiding material on the wall of the sound guiding column. The sound will enter the sound guiding material on the vertical wall and collide continuously to reduce the energy of the sound. After multiple vertical sound guiding materials, the non-target sound waves entering the sound guiding column will be greatly reduced to improve the echo in the target direction, making the target echo real and accurate (mainly filtering out two miscellaneous echoes, retaining the target echo, and accurately transmitting and displaying).
[0099] See also Fig.12 , Fig.12 This is an ultrasound-guided three-dimensional image. The columnar structure in the image is the sound-conducting material, and the outside of the columnar structure is the sound-proofing material (not shown for a good-looking image). The sensor (pressure element) is connected under the sound-conducting material, and the sensor corresponds to the transmission line, which is transmitted to the processor to obtain the corresponding value. The corresponding value is displayed on the display screen in the form of points through the converter, forming a three-dimensional result that the doctor can observe better, including: the value of the echo strength, direction, angle, level, color, etc.
[0100] See also Fig.13 , Fig.13This is a three-dimensional diagram of cross-guiding. In multiple vertical planes, the guidance is left-biased, right-biased, and centered. The guidance in multiple vertical planes does not intersect, so we can get images in multiple directions in multiple planes. This is very important in clinical processes, especially when the overall structure of the vertebral body is displayed during spinal puncture (because the vertebral body is bone, it often blocks the echo of ultrasound, making it impossible to display the structure behind it. Multi-direction can sense the echo in other directions to display the structure around the vertebral body, and display the puncture direction and puncture needle, which is beneficial for spinal puncture). An outward guide device can be set on the outermost side, so that outward images can be obtained. This phenomenon may not be very useful in actual processes.
[0101] See also Fig.14 , Fig.14 It is a long-axis side view of stereo ultrasound, that is, a schematic diagram of enhanced ultrasound. In the middle of the stereo ultrasound probe are multiple rows of fixed guiding chipsets, on both sides are multiple rows of adjustable guiding chipsets, above the multiple rows of adjustable guiding chipsets there is an angle adjuster, under the multiple rows of fixed guiding chipsets there are echo guiding devices, the echo guiding devices can be parallel, divergent, etc., and the direction of the echo guiding devices under the multiple rows of adjustable guiding chipsets on both sides is toward the middle, so that an area with crossed echoes will be obtained (the figure shows echoes in the left, right, and bottom directions, and there are actually crossed echoes in five directions of front and back). In this way, an enhanced stereo ultrasound area can be obtained. Due to the filtering effect of the ultrasound guiding device on the echo, the echo is more accurate and the tissue resolution is clearer. Coupled with the display in five directions, the enhanced ultrasound area display is more realistic, clear, and detailed.
[0102] The advantages of ultrasound: minimal radiation, continuous and timely images, and the ability to measure blood flow. Therefore, it has outstanding advantages in measuring blood vessels and blood flow. With its enhanced effect, we can do more things.
[0103] (1) Measurement and detection of coronary vessels and blood flow;
[0104] (2) measurement, detection, and guidance of tumor blood supply;
[0105] (3) detection and guidance of intravascular procedures;
[0106] (4) Extravascular procedures;
[0107] (5) Searching for bleeding points in blood vessels (of course, angiography is the best).
[0108] Measurement and detection of coronary vessels and blood flow:
[0109] (1) The coronary artery is not a planar structure, but also a continuous channel. More importantly, it is in motion, so it is difficult to detect in two, three, or even four dimensions.
[0110] (2) The present invention is a three-dimensional structure that can present the overall structure of the coronary artery;
[0111] (3) With its enhanced effect, it can better display the structure of the coronary artery and monitor blood flow;
[0112] (4) Through the filtering effect of echoes, the mixed echoes are eliminated and the target echo is better obtained, so that the target echo can be obtained more accurately and displayed, thereby better displaying the coronary artery.
[0113] Measurement, monitoring and guidance of tumor blood supply:
[0114] Due to the three-dimensionality and timeliness of ultrasound, all blood vessels supplying the tissue can be displayed, including the thick blood vessels with obvious blood supply (including: the shape of the blood vessels, the size of the blood vessels, the relationship and location of the blood vessels and tumors; the selection of the location for blood vessel ligation, etc.), which is very important for tumor surgery.
[0115] Detection and guidance of intravascular procedures:
[0116] Existing interventional displays are all two-dimensional (planar), while the present invention is three-dimensional, timely, and has extremely low radiation, so it has advantages. For example, during coronary angiography, sometimes the guidewire cannot enter the left or right main coronary artery from the aorta. The reasons are: 1. The displayed guidewire is in a vertical plane, but it may be tilted forward and backward. 2. The left and right main coronary artery openings are not on the left and right sides, and may also be tilted forward and backward, so they do not match up and cannot be inserted into the coronary artery. (There was a case: the guidewire was not inserted for more than an hour during coronary angiography, and it was repeatedly rotated, causing the guidewire to be entangled in the brachial artery.) If there is stereo ultrasound, we can obtain the three-dimensional spatial relationship between the guidewire and the left and right main coronary artery entrances, and can directly insert the corresponding guidewire into the coronary artery.
[0117] Extravascular procedures:
[0118] Blood vessels are three-dimensional and often not in the same plane, such as the radial artery and coronary artery. In addition, the outside of the plane is a point. The inside of the plane requires the puncture needle, probe, and target object to be in the same plane, which requires high operation and control. If it is a three-dimensional ultrasound, it is all in the same plane, and the puncture needle, target object, and surrounding tissues are clearly visible. In this way, the difficulty of puncture is reduced, the probability of successful puncture is increased, accidental injury to other tissues is reduced, and complications are reduced. At the same time, more people are learning and using it, and the popularity rate is higher.
[0119] See also Fig.15 , Fig.15This is a schematic diagram of the chips and echo directions on the front of a stereo ultrasound probe. In the schematic diagram of the chips on the front of the stereo ultrasound probe, a group of chips arranged side by side in the middle of the probe are fixed directional chipsets, and the two chips arranged side by side on both sides are adjustable directional chipsets.
[0120] The longitudinal echo diagram of the chipset shows vertical echo lines (black lines), left-leaning echo lines (red lines) and right-leaning echo lines (blue lines), which may not appear on ultrasound. The diagram is drawn for the sake of appearance.
[0121] If the chipset in the middle is in multiple directions + the upper and lower sides are also in multiple directions, our stereo ultrasound will eventually be more real, rich and all-round.
[0122] At the same time, the chipsets on both sides can be adjusted as needed to obtain enhanced regional target organization.
[0123] See also Fig.12 Schematic diagram of the principle of stereo ultrasound:
[0124] 1) When the echo bounces back from the tissue to the tissue surface, it is transmitted to the probe surface through the coupling agent;
[0125] 2) The contact layer on the probe surface receives the echo and transmits it to the guide conduction layer;
[0126] 3) The guiding conductive layer transmits the sound in the target direction to the sensing layer (i.e., the pressure element);
[0127] 4) The sensing layer is connected to a data line, and the other end of the data line is connected to a processor;
[0128] 5) The processor transmits the data obtained by the sensing layer to the converter;
[0129] 6) The converter displays the acquired data directly on the display screen, allowing the operator to observe the graph;
[0130] 7) The displayed graphics are divided into two-dimensional graphic screen and three-dimensional graphic screen.
[0131] The two-dimensional image and three-dimensional image screens can be combined into upper and lower screens. The two-dimensional image and three-dimensional image dual screen can increase the recognition effect of the operator, and increase the judgment and diagnosis effect. At the same time, it provides good guidance for beginners, making it easier for beginners to learn ultrasound, and also provides help for future AI ultrasound technology.
[0132] See also Fig.16 , Fig.16 The echo intensity color display key and various echo selection rods make it easy to observe through the color display of different echo intensities, which can improve the recognition rate of tissues:
[0133] (1) Color Key Bar:
[0134] From no echo to strong echo, the corresponding colors are 1. black (because the background color of the current display is black), 2. gray, 3. light cyan, 4. cyan, 5. light blue, 6. blue, 7. dark blue, 8. light yellow, 9. yellow, 9. orange, 9. light red, 10. red, 11. purple;
[0135] The color key corresponds to each color. The color key can be pressed and rebounded. Pressing: it can indicate the color of the echo of that intensity is displayed. Rebounding: it can indicate not to display the color of the echo of that intensity. The echo of that intensity is replaced by the color of the next color key. The purpose is to reduce the interference of other colors (too many colors may cause color dizziness to some operators).
[0136] In short, the color key can be turned on and off;
[0137] The color of the color key can be adjusted freely (you can choose your favorite color, because this color is designed by me, not the color that everyone likes and the color that is convenient, and there will be a consensus color key color in the end);
[0138] Generally, the echo intensity ranges from low to high, and the corresponding color key ranges from light to dark. (This makes it easier to display abnormal echoes in tissues in stereo ultrasound, such as stones in the urinary and digestive systems, the location of multiple calcification points in the thyroid gland, and bubbles in blood vessels (various air embolisms: laparoscopy, craniotomy, spine)).
[0139] Areas of certain echogenicity correspond to a color (which can be better represented by identical tissues).
[0140] (2) Select a certain interval to display, for the purpose of easy observation.
[0141] Middle display: Only the middle part of the original stereo image is displayed, so that the middle tissue image can be better observed (just like a rectangular cake cut vertically into three parts, with the front and back sides not displayed, only the middle area is displayed);
[0142] Front and rear oblique display: the original rectangular stereoscopic display image is cut off from the front and rear triangles, and the original rectangular parallelepiped is changed into a trapezoidal body. The purpose is to reduce the tissue image in front and better display the target tissue (which provides convenience for various punctures);
[0143] Various echo selector levers:
[0144] Intensity echo range display rod: removes low echoes or strong echoes to better display the target tissue. Generally, it mainly reduces low-echo images, better displays the target tissue, and makes the image clearer.
[0145] Color range selection lever: select the color of the echo area, which has actually been replaced by the color key
[0146] Color depth adjustment lever: darken or lighten the color of the image for better observation by the operator.
[0147] See also Figure 6 Three-dimensional muscle display diagram:
[0148] (1) The echo intensity in the fascia layer of the muscle is high, showing moderate echoes and appearing in yellow;
[0149] (2) At the two ends of the tendon, the echo intensity is higher, showing strong echoes and appearing as purple;
[0150] (3) In the middle of the muscles there are capsules of various muscle bundles, which appear as lower echoes and appear as small blue capsules.
[0151] See also Fig.17 , Ultrasound-guided design:
[0152] Solution 1: Drill holes in the filter material (which can be organic material or dry wood material), then inject sound-conducting material into the holes, and then use ultrasonic vibration to expel the gas in the sound-conducting material, and wait for the material to solidify.
[0153] Option 2: Use metal materials as sound-conducting materials (metals conduct sound quickly, have strong toughness, good continuity, and can be used for a longer time. Especially gold: better ductility and strong plasticity.)
[0154] First, shape the metal into the target shape (vertical parallel type, angle type, oblique type, vertical left and right oblique cross type)
[0155] Add sound insulation material into the shaping material, wait for the sound insulation material to solidify, grind the metal filtering sound-conducting material into the target shape and size, and connect it to the pressure sensor.
[0156] See also Fig.18 , select a partial area of the displayable stereoscopic image to display, reduce the interference of other images, and better display the target image, such as: the direction of puncture, the size, shape, blood flow relationship of the tumor, etc.
[0157] Displaying the middle longitudinal area image of the entire image and hiding the images of the areas on both sides can better display the three-dimensional graphics of the middle area (the area images can be widened or narrowed, either longitudinally or transversely).
[0158] See also Fig.19 , Fig.19To display the image in the ladder column area, select the bottom plane as the basis for the entire display image, adjust the height of the ladder column, select the width of the top surface, and form a ladder column display area (purpose: to reduce the interference of the tissue above, directly display the structure of the target layer, and better display the structure of the target area).
[0159] See also Fig. 20 , select different local fields of view for display, enhancement, echo intensity selection, color adjustment, increase inspection effect, and display effect, and at the same time increase ease of operation and controllability. Ultrasound has a good detection effect on blood vessels and blood flow. The vascular network is three-dimensional and of varying thickness. Because of the present invention, the accuracy, precision, multi-directionality and three-dimensionality of ultrasound are increased, and there are many breakthrough innovations in vascular inspection and detection, such as: ultrasound can examine coronary arteries and their branches, can detect tumor blood supply, and can ultrasonically locate tumors. Continuous detection and non-invasive detection will be two important points in the future.
[0160] See also Fig.21 The ultrasound probe of the present invention can also combine multiple perspective images to obtain a three-dimensional perspective. For example, the fetus must pass through the pelvic cavity during delivery, but the large volume of the pelvis prevents front and side ultrasound detection. Therefore, the probe on the pelvis can only see the image on the pelvis, and the probe under the pelvis can only see the lower part of the image. Therefore, the obtained ultrasound image is incomplete. By combining the upper and lower three-dimensional images, the entire three-dimensional image can be displayed, which is helpful to judge the overall condition of the fetus.
[0161] As an extension of the present invention, the two-dimensional image can display the plane as a dotted line in the three-dimensional figure, which can better help the operator find the target plane.
[0162] As another extension of the present invention, through tissue stereo imaging and Doppler blood flow stereo imaging, the three-dimensional conditions of tissues and blood vessels can be determined to judge diseases. At the same time, it can reduce and avoid damage to small and medium-sized blood vessels caused by puncture and surgical operations, reduce puncture bleeding, and ensure the safety of patients.
[0163] As another extension of the present invention, a chip point on a vertical straight line can receive echoes from tissues in multiple directions, thereby providing a wider signal viewing angle. Multiple chip points receiving echoes from the same tissue point can make the target tissue display clearer and more realistic, while also having an enhanced display effect (without increasing the acoustic wave power to achieve the enhanced effect). At the same time, if the signal from one chip point cannot be received, there are other chip points that can receive it (regardless of the existing three-dimensional or four-dimensional probes, plane reception or arc reception, the same tissue point can only receive one signal. If this echo signal is interfered with or blocked, the echo signal of this tissue point cannot be received, and the image of this tissue point cannot be displayed on the display screen).
[0164] As another extension of the present invention, the three-dimensional image is set to correspond to the dotted line of the two-dimensional image, and the two-dimensional image display can be set not only to longitudinal and transverse directions, but also to 15°, 30°, 45°, 60°, and multiple directions to observe tissue images.
[0165] As another extension of the present invention, when only strong echoes are displayed, the appearance of the bones can be displayed as a whole, which is of great help in diagnosing fractures and guiding treatment.
[0166] The working principle of the present invention is as follows: based on the propagation and reflection characteristics of ultrasound in human tissue, the precise design of the directional conduction layer is used to achieve fine control and filtering of ultrasound. Specifically, the role of the directional conduction layer is similar to a high-level "sound wave gate", which only allows the target sound wave to pass through, while effectively blocking and filtering out the interfering sound wave oblique wave. This design greatly improves the signal-to-noise ratio of ultrasound detection, ensuring that the received ultrasound echo is purer and clearer. Next, the filtered ultrasound echo is digitized using the existing B-ultrasound imaging principle to form a three-dimensional image and a plan view of the detection site. These images are intuitively displayed on the display, helping doctors to intuitively understand the pathological conditions in the patient's body. In terms of image display, the present invention uses color coding technology to distinguish echo areas of different intensities by different colors. This visualization processing method not only improves the image recognition, but also further improves the doctor's diagnostic efficiency. At the same time, by adjusting the color depth and selecting different echo intensity areas In the present invention, doctors can customize the image display effect more flexibly to meet different clinical needs. In terms of image search and navigation, the present invention allows doctors to change the exploration area and position by adjusting the filter channel of the directional conduction layer to different angles. This flexibility allows doctors to search for target lesions more conveniently and improves the accuracy and efficiency of exploration. The present invention also realizes the navigation function of the puncture needle by adjusting the physical structure of the probe device. This design allows the puncture needle to generate echoes during the puncture process, which are combined with the detected tissue position for processing and imaging, thereby guiding doctors to perform puncture operations more accurately. This function not only improves the accuracy and safety of the operation, but also reduces the surgical risks of patients. The present invention realizes the fine control and efficient use of ultrasound by adopting a variety of technical means such as the design of the directional conduction layer, color coding technology, image search and navigation functions, and puncture needle navigation functions, providing more accurate, reliable and convenient tools and methods for medical diagnosis and surgical treatment.
[0167] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
Claims
1. A probe device with a filtering structure and an echo guide, characterized in that: The invention comprises a filtering module, an imaging module and a puncture needle. The filtering module comprises an acoustic wave contact layer. A fixed guiding conduction layer is arranged at the bottom of the acoustic wave contact layer. An acoustic wave sensor is arranged at the bottom of the fixed guiding conduction layer. The bottom of the acoustic wave sensor is connected to a processor through a transmission line. The bottom of the processor is connected to a converter through a transmission line. The bottom of the converter is connected to a display screen through a transmission line. The display screen displays a stereoscopic image and a two-dimensional image respectively. The stereoscopic image can display a positive external deflection image, a positive median image, a right positive deflection image and a left positive deflection image. These four directions are a general direction relationship. There are various angles in each direction. The deflection angles in each row can be different, including but not limited to 5°, 10°, 15°20°, 30° and 45°. Different angles are selected according to needs to select the manufacturing angle, and the corresponding image is displayed by accurately corresponding to the image formation angle. There is not only one row at each angle, but multiple rows can be arranged in parallel at one angle, which can save costs. Ultrasonic guidance can keep the direction and structure of the crystal receptor below unchanged, and can accept echoes from different directions. Echoes from non-target directions are filtered through multi-directional echo correction, which can reduce mixed echoes and make the displayed tissue more realistic.
2. The probe device with filtering structure and echo guidance according to claim 1, characterized in that: The display screen comprises an echo intensity interval selection rod, a display area, a color interval selection rod and a color depth adjustment rod, so as to improve the effects of stereoscopic display and target object recognition.
3. The probe device with filtering structure and echo guidance according to claim 1, characterized in that: The conductor is a metal wire with a shaping effect, the filter structure material is rubber with tiny bubble cavities, and metal particles are added to the filter structure to filter sound waves in non-target directions.
4. The probe device with filtering structure and echo guidance according to claim 2, characterized in that: The display area adopts a black-bottom display screen, and the display area includes a non-echo area, a low-echo area, a medium-echo area, and a strong-echo area.
5. The probe device with filtering structure and echo guidance according to claim 4, characterized in that: The anechoic area is displayed as colorless and transparent and as a strong echo area, so that the relationship between the puncture object and the target object can be displayed; the display area can adjust the display range to filter out the target area.
6. The probe device with filtering structure and echo guidance according to claim 4, characterized in that: The hypoechoic areas are shown in light cyan and green.
7. The probe device with filtering structure and echo guidance according to claim 4, characterized in that: The moderately echoic areas are shown in white and yellow.
8. The probe device with filtering structure and echo guidance according to claim 4, characterized in that: The strong echo area is displayed in orange and red, and different colors can be selected according to the display of the echo intensity of each tissue.
9. A method for using a probe device with a filtering structure and an echo guide, characterized in that: A probe device with a filter structure and an echo guide according to any one of claims 1 to 8, specifically comprising the following steps: Step 1: placing the probe device at the target site to make the acoustic wave contact layer on the probe device contact the target site; Step 2: The directional conductive layer can filter out interfering acoustic oblique waves, ensuring that the ultrasonic echo received by the probe contains only the positive wave of the target acoustic wave, which can filter out clutter to the greatest extent and achieve clear imaging of the probed part; Step 3: Based on the existing ultrasonic imaging principle, the filtered echoes of the probed part are directly processed to form a stereogram and a plane diagram of the part, which are displayed on the display, and the plane diagram is marked on the stereogram with a dotted outline; Step 4: Adjust the filter channel of the directional conduction layer to different angles. The direction of the filter channel cannot be changed, but has been fixed during production. If the filter channel can change direction, it will increase production costs and technical difficulty, but it can be written into it as a technical innovation to adjust the exploration area and position to facilitate the search for the target lesion that needs to be explored. Adjusting the exploration area and position is a display effect of the display screen, which is to not display a certain area and only display the target area; Step 5: Based on the existing ultrasound principle, use colors to distinguish the echo intensity of different echo areas, realize the visualization of echo intensity in different areas, and better display the tissue structure. Because the original display is gray and white intensity, it can be distinguished on a plane. If there are many layers, forming a three-dimensional figure, the original gray and white are very easy to confuse. If different echo intensities are displayed in different colors, it will be easier to display, thus reducing confusion. Step 6: Set the filtering function and adjust the threshold to hide the colorless and black areas, that is, remove the non-target areas to further observe the target areas; Step 7: Adjust the physical structure of the probe device so that some sound waves are emitted at an angle with other sound waves. This can assist in puncturing the target area with the puncture needle. Because the original echo waves are parallel to the same plane, the echo of the puncture needle cannot be obtained. This improved setting can obtain echoes in multiple directions so that the puncture needle can also generate echoes. The puncture needle can be navigated based on the echo position and the detected tissue position combined with processing and imaging. Combined with the three-dimensional imaging of the target object, the relationship between the puncture needle and the target object is clearly visible, and puncture and adjustment are clearer and easier, with a higher success rate.
10. The method for using the probe device with a filtering structure and an echo guide according to claim 9, characterized in that: Exploration images of the same part at different angles can be combined to generate a stereoscopic image, which is used for further auxiliary diagnosis.
