Description

Technical Field

[0001] This invention relates to the field of thyroid and lymph node scanning devices, specifically a longitudinal automatic ultrasound concave multi-probe scanning device for thyroid and lymph nodes. Background Technology

[0002] In the field of medical imaging, thyroid and cervical lymph node ultrasound, as a non-invasive imaging technique, has become a core method for diagnosing thyroid and cervical lymph node-related diseases due to its significant advantages such as convenient and rapid operation and real-time dynamic imaging. From a clinical application perspective, thyroid and cervical lymph node ultrasound can provide a comprehensive assessment of the thyroid gland's morphology, size, and structure, clearly showing the presence of lesions within the thyroid gland. It can also accurately determine the location, number, border clarity, morphological regularity, internal echo characteristics, and lymph node metastasis of lesions, providing important references for subsequent examinations or surgical treatment.

[0003] However, in current clinical applications, existing ultrasound scans usually rely on the ultrasound physician to manually operate the probe. The ultrasound physician needs to perform both scanning and diagnosis simultaneously, which is a heavy workload. Furthermore, single-probe automatic scanning devices cannot perfectly cover lymph node scanning, and are prone to scanning blind spots, reducing the completeness and accuracy of the examination. In addition, the physiological characteristics of the patient's neck (neck length, width, and curve) vary, which makes it difficult for the probe to fit effectively on the neck of some patients, easily forming air gaps that lead to poor ultrasound coupling and affect image quality. Summary of the Invention

[0004] This invention aims to provide an automated longitudinal ultrasound scanning device for thyroid and lymph nodes using a multi-probe concave surface. It solves the problems of existing ultrasound scanning methods that rely on manual operation by the ultrasound physician holding the probe, which cannot separate scanning from diagnosis and results in a large workload; single-probe automated scanning devices that cannot perfectly cover lymph node scanning, easily leading to blind spots and reducing the completeness and accuracy of the examination; and the technical problem that conventional linear array probes cannot effectively fit the curve of the patient's neck.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A multi-probe longitudinal automatic ultrasound scanning device for thyroid and lymph nodes includes an arc-shaped ultrasound guide pad and a scanning assembly. The scanning assembly includes a support frame, one end of which is connected to a first housing. A driving assembly is housed within the first housing, and an ultrasound probe is connected to the driving end of the driving assembly. The ultrasound guide pad is positioned between the patient's neck and the ultrasound probe. The driving assembly drives the ultrasound probe to slide longitudinally along the patient's neck. Second housings are connected to both sides of the first housing, and each second housing contains a driving assembly with an ultrasound probe connected to its driving end. Three ultrasound probes are laterally distributed along the patient's neck, with the surface of each probe away from the support frame being an arc-shaped concave surface. The curvature of the ultrasound guide pad is adapted to match the ultrasound probe, ensuring close contact between the ultrasound probe and the ultrasound guide pad. The support frame includes a controller connected to the driving assembly.

[0007] Furthermore, the drive assembly includes a lead screw, a nut, and a motor. The lead screw is rotatably connected to the first housing or the second housing. The nut is threadedly connected to the lead screw and is slidably connected to the first housing or the second housing along the axial direction of the lead screw. The nut is connected to the ultrasonic probe. The motor is used to drive the lead screw to rotate. The controller is connected to the motor.

[0008] Furthermore, the first housing has a groove along the axial direction of the lead screw, the nut is connected to a matching slide rail, the slide rail is slidably connected in the groove, and the nut is connected to the ultrasonic probe.

[0009] Furthermore, two arc-shaped guide rods are rotatably connected to both sides of the first housing, and sliders are slidably connected to the arc-shaped guide rods. The second housing is connected to the two sliders. The first housing is rotatably connected to a first telescopic member, and the telescopic end of the first telescopic member is rotatably connected to the second housing. The nut inside the first housing is connected to the ultrasonic probe through a second telescopic member.

[0010] Furthermore, the first housing is provided with a through groove, one end of the second telescopic member is connected to a nut, and the other end of the second telescopic member passes through the through groove and is connected to the ultrasonic probe.

[0011] Furthermore, a limiting element is connected to the end of the arc-shaped guide rod away from the first housing.

[0012] Furthermore, the nut inside the second housing is connected to the ultrasonic probe via a third telescopic component.

[0013] Furthermore, the third telescopic component is a hydraulic telescopic rod or an electric telescopic rod.

[0014] Furthermore, it also includes an adjustment component for adjusting the height of the first housing.

[0015] Furthermore, it also includes a support base, which is connected to a telescopic rod, the telescopic end of which is connected to the end of the support frame away from the first housing.

[0016] The principles and beneficial effects of the technical solution are as follows:

[0017] 1. The present invention provides a longitudinal automatic ultrasound concave multi-probe scanning device for thyroid and lymph nodes. The inner and outer walls of the arc-shaped ultrasound guide pad are both arc-shaped, which is adapted to the human neck and conforms to ergonomics. It is made of agar and is similar to transparent jelly. When placed on the neck of the examinee, it conforms to the neck and changes the curvature. During use, coupling agent needs to be applied to the contact surface. Coupling agent is applied between the examinee's neck and the ultrasound guide pad to avoid air gaps. Coupling agent is applied between the probe and the ultrasound guide pad to avoid gaps and lubricate so that the probe can slide. The device is placed between the patient's neck and the ultrasound probe, ensuring a seamless and tight contact between the probe and the neck for optimal ultrasound coupling. One end of the support frame is fixed to a bed board, examination device, table, or other fixed object, while the other end connects to the first housing. Second housings are connected to both sides of the first housing. Drive components are housed within the first housing and the two side second housings. The drive end of each drive component is connected to the ultrasound probe, which automatically scans the neck longitudinally. A controller controls the longitudinal scanning range and speed of the drive component, eliminating the need for manual operation by the ultrasound physician holding the probe. This method is convenient, provides excellent scanning results, and reduces the workload of the ultrasound physician. The central ultrasound probe is used for scanning... The ultrasound probes are used to scan the thyroid region in the midline of the neck, with two additional probes on either side to supplement the scan of the lateral lobes of the thyroid gland and the lateral cervical lymph nodes. This allows for simultaneous scanning of both the thyroid and lymph node areas, improving the completeness and accuracy of the examination. Furthermore, the three ultrasound probes are arranged horizontally side-by-side along the patient's neck, covering both the thyroid and lymph node areas. This avoids the blind spots that can occur with single-probe automatic scanning devices, which often struggle to perfectly cover all lymph nodes, further enhancing the accuracy and completeness of the scan. Additionally, the surface of the ultrasound probe furthest from the support frame is designed with a concave arc, and the curvature of the ultrasound guide pad is adapted to match the ultrasound probe, ensuring a close fit between the probe and the guide pad. This provides a better fit to the neck curve than traditional linear array probes, increasing scanning accuracy.

[0018] 2. The present invention provides a longitudinal automatic ultrasound concave multi-probe scanning device for thyroid and lymph nodes. The driving component includes a lead screw, a nut, and a motor. The motor drives the lead screw to rotate. Under the action of the housing and the thread, the nut drives the ultrasound probe to move linearly along the axis of the lead screw. That is, the ultrasound probe can move linearly along the longitudinal direction of the examinee's neck to achieve automatic scanning of the thyroid and lymph node areas in the neck. It has a high degree of automation, avoids scanning blind spots, and the controller can control the speed, number of rotations, and direction of rotation of the motor to adjust the scanning speed, scanning distance, and scanning direction, further increasing the scanning accuracy. In addition, the second housings on both sides are slidably connected to the first housing along the outer circumference of the ultrasonic guide pad to facilitate adjustment of the position of the ultrasonic probe on the ultrasonic guide pad. Specifically, each side of the first housing is rotatably connected to an arc-shaped guide rod (when the ultrasonic guide pad is placed on the patient's neck, it will conform to the neck and change its curvature, causing deformation; the arc-shaped guide rod is rotatably connected to the first housing to conform to the neck). The arc-shaped guide rod is slidably connected to a slider, and the second housing is connected to the two sliders. A first telescopic component is connected between the first housing and the second housing. The first telescopic component is used to drive the second housing to slide along the arc-shaped guide rod. In addition, the nut inside the first housing is connected to the ultrasonic probe through the second telescopic component. After the ultrasonic probe in the middle is scanned, it can be retracted upwards using the second telescopic component to release space and adjust the position of the ultrasonic probes on both sides. Then, the first telescopic component is used to drive the second housings on both sides to move closer to the middle along the arc-shaped guide rod, so that the scanning area of ​​the probes on both sides covers the edge of the scanning area of ​​the probe in the middle, further avoiding scanning blind spots at adjacent points of different probes. Furthermore, the two arc-shaped guide rods serve to guide and limit the probe, preventing it from rotating and affecting the scanning effect. The nut inside the second housing is connected to the ultrasonic probe via a third telescopic component, allowing for fine-tuning of the ultrasonic probes on both sides to better fit the ultrasonic sound guide pad and further increase scanning accuracy.

[0019] 3. The present invention provides a longitudinal automatic ultrasound concave multi-probe scanning device for thyroid and lymph nodes. The device also includes a support base, which is connected to a telescopic rod. The telescopic end of the telescopic rod is connected to the end of the support frame away from the first housing, which can fix the support frame. The telescopic rod can adjust the height of the probe so that the entire scanning assembly can be raised to release the space between the ultrasound probe and the examination bed, so that the examinee can lie in a suitable position. The position of the ultrasound probe can be adjusted by the telescopic rod to make it fit with the ultrasound sound guide pad. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0028] Example 1

[0029] like Figures 1 to 3As shown, a multi-probe longitudinal automatic ultrasound scanning device for thyroid and lymph nodes includes an arc-shaped ultrasound guide pad 1 and a scanning assembly. The scanning assembly includes a support frame 2, which is fixed to an operating table, support, or tabletop. The support frame can be configured as a telescopic structure (electric telescopic rod, hydraulic cylinder, or telescopic sleeve, etc.). One end of the support frame 2 is connected to a first housing 3, and a driving assembly is provided inside the first housing 3. The driving end of the driving assembly is connected to an ultrasound probe 14. The ultrasound guide pad 1 is positioned between the patient's neck and the ultrasound probe 14. The driving assembly is used to drive the ultrasound probe 14 to slide longitudinally along the patient's neck. The lower contact surfaces are coated with coupling agent to prevent air gaps and provide lubrication to facilitate the sliding of the ultrasonic probe 14; the drive assembly includes a lead screw 4, a nut 5, and a motor 7. The lead screw 4 is rotatably connected to the first housing 3. The nut 5 is threadedly connected to the lead screw 4, and the nut 5 is slidably connected to the first housing 3 along the axial direction of the lead screw 4. That is, the first housing 3 has a groove 6 along the axial direction of the lead screw 4. The nut 5 is connected to a matching slide rail, which is slidably connected in the groove 6. The nut 5 is connected to the ultrasonic probe 14; the motor 7 is connected to the second housing 10 and is used to drive the lead screw 4 to rotate; the support frame 2 is equipped with a controller 15, and the controller 15 is connected to the motor 7.

[0030] The first housing 3 is slidably connected to the second housing 10 on both sides. Specifically, two arc-shaped guide rods 8 are rotatably connected to both sides of the first housing 3, and sliders 9 are slidably connected to the arc-shaped guide rods 8. The end of the arc-shaped guide rod 8 away from the first housing 3 is connected to a limiter 19 to prevent the slider 9 from slipping off the arc-shaped guide rod 8 due to accidental circumstances. The second housing 10 is connected to the two sliders 9. The first housing 3 is rotatably connected to the first telescopic member 11. The telescopic end of the first telescopic member 11 is rotatably connected to the second housing 10. The nut 5 inside the first housing 3 is connected to the ultrasonic probe 14 through the second telescopic member 12. That is, the first housing 3 is provided with a through groove 18. One end of the second telescopic member 12 is connected to the nut 5, and the other end of the second telescopic member 12 passes through the through groove 18 and is connected to the ultrasonic probe 14. The first telescopic member 11 is used to drive the second housing 10 to slide along the arc-shaped guide rod 8, thereby driving the ultrasonic probe 14 to slide along the outer circumferential direction of the ultrasonic sound guide pad 1. In addition, each of the two second housings 10 has a drive assembly. The drive end of the drive assembly is connected to an ultrasonic probe 14. The connection between the drive assembly and the second housing 10 is the same as that between the first housing 3 and the second housing 10. That is, the second housing 10 has a groove 6 along the axial direction of the lead screw 4. The nut 5 is connected to a matching slide rail, which is slidably connected in the groove 6. The nut 5 in the second housing 10 is connected to the ultrasonic probe 14 through a third telescopic member 13. That is, the second housing 10 has a through groove 18. One end of the third telescopic member 13 is connected to the nut 5, and the other end of the third telescopic member 13 passes through the through groove 18 and is connected to the ultrasonic probe 14. The three ultrasonic probes 14 are positioned along the neck of the examinee. The ultrasonic probe 14 is laterally distributed, and the surface of the side away from the support frame 2 is set as an arc-shaped concave surface. The curvature of the ultrasonic sound guiding pad 1 is adapted to the ultrasonic probe 14 so that the ultrasonic probe 14 fits the ultrasonic sound guiding pad 1. The first telescopic member 11, the second telescopic member 12 and the third telescopic member 13 can be hydraulic telescopic rods or electric telescopic rods. The first telescopic member 11, the second telescopic member 12 and the third telescopic member 13 are connected to the controller 15, and the controller 15 controls their extension or shortening. The first telescopic member 11, the second telescopic member 12 and the third telescopic member 13 can also be a telescopic tube formed by two sleeves connected together, and the two sleeves are fixed by bolts.

[0031] Example 2

[0032] like Figure 4The difference between this embodiment and Embodiment 1 is that this embodiment further includes an adjustment component, which includes a support base 16 placed on the ground. The support base 16 is connected to a telescopic rod 17, and the telescopic end of the telescopic rod 17 is connected to the end of the support frame 2 away from the first housing 3, which can fix the support frame 2, thereby enabling the ultrasound probe 14 to perform scanning stably and reducing the burden on the ultrasound doctor. The telescopic rod 17 can be a hydraulic telescopic rod or an electric telescopic rod, and the telescopic rod 17 is connected to a controller 15, which controls its extension or retraction; the telescopic rod 17 can also be a telescopic tube formed by two sleeves connected together, and the two sleeves are fixed by bolts.

[0033] The specific implementation process is as follows:

[0034] When using this device, apply coupling agent to both the upper and lower contact surfaces of the ultrasonic guide pad 1, and place the ultrasonic guide pad 1 against the patient's neck so that the ultrasonic probe 14 is in contact with the outer surface of the ultrasonic guide pad 1. The controller 15 controls the central motor 7 to start. The motor 7 drives the ultrasonic probe 14 to scan the thyroid region along the longitudinal direction of the ultrasonic guide pad 1 through the lead screw 4 and nut 5. After the scan is completed, the second telescopic member 12 drives the central ultrasonic probe 14 to retract upward to release space. Then, the first telescopic member 11 drives the second housings 10 on both sides to slide towards the center so that the scanning areas of the probes on both sides cover the edge of the scanning area of ​​the central probe. The motors 7 on both sides are started. The motors 7 drive the ultrasonic probes 14 on both sides to scan the lymph node region along the longitudinal direction of the ultrasonic guide pad 1 through the lead screw 4 and nut 5.

[0035] The arc-shaped ultrasound guide pad 1 has arc-shaped inner and outer walls that conform to the human neck, conforming to ergonomics. It is placed between the patient's neck and the ultrasound probe 14. Coupling agent is applied to both the upper and lower contact surfaces of the guide pad to prevent air gaps and provide lubrication, facilitating probe sliding and ensuring seamless, tight contact between the probe and the neck for good ultrasound coupling. The drive assembly drives the ultrasound probe 14 to slide along the axial direction of the ultrasound guide pad 1 for automatic scanning. The controller 15 controls the longitudinal scanning range and speed of the drive assembly, avoiding manual operation by the ultrasound physician holding the probe, making operation convenient and improving scanning results. The central ultrasound probe 14 is used to scan the thyroid region in the center of the neck, and the two sides... The ultrasound probe 14 is used to scan the edge of the thyroid gland and the cervical lymph node area, and can scan the thyroid gland and lymph node area simultaneously, improving the completeness and accuracy of the examination. Moreover, the three ultrasound probes 14 are distributed horizontally side by side along the patient's neck, covering the thyroid gland and lymph node area of ​​the neck, avoiding the blind spots that are easily generated by the single probe automatic scanning device, which is difficult to perfectly cover the lymph node scanning. This further increases the accuracy and completeness of the scanning. In addition, the surface of the ultrasound probe 14 away from the support frame 2 is set as an arc concave surface, and the curvature of the ultrasound guide pad is adapted to the ultrasound probe, so that the ultrasound probe 14 fits the ultrasound guide pad 1 better than the traditional linear array probe, which fits the neck curve better and increases the scanning accuracy.

[0036] The drive assembly includes a lead screw 4, a nut 5, and a motor 7. Under the action of the housing and the thread, the ultrasound probe 14 can move linearly along the longitudinal direction of the examinee's neck to achieve automatic scanning of the thyroid and lymph node areas in the neck. This achieves a high degree of automation and avoids blind spots. The controller 15 can control the speed, number of rotations, and direction of rotation of the motor 7 to adjust the scanning speed, scanning distance, and scanning direction, further increasing scanning accuracy. In addition, the second housings 10 on both sides are slidably connected to the first housing 3 along the arc-shaped guide rod 8, and the arc-shaped guide rod 8 is rotatably connected to the first housing 3 to facilitate adjustment of the position of the ultrasound probe 14 on the ultrasound guide pad 1. After the ultrasound probe 14 in the middle has finished scanning, it is retracted upwards using the second telescopic member 12 to release space and adjust the position of the ultrasound probes 14 on both sides. Then, the first telescopic member 11 is used to make the scanning area of ​​the probes on both sides cover the edge of the scanning area of ​​the central probe, further avoiding blind spots at adjacent points of different probes. The nut 5 inside the second housing 10 is connected to the ultrasonic probe 14 through the third telescopic member 13, which can finely adjust the ultrasonic probes 14 on both sides to make them fit the ultrasonic sound guide pad 1 better, thereby further increasing the scanning accuracy.

[0037] The device also includes a support base 16, which is connected to a telescopic rod 17. The telescopic end of the telescopic rod 17 is connected to the end of the support frame 2 away from the first housing 3, which can fix the support frame 2. The telescopic rod 17 can adjust the height of the probe so that the entire scanning assembly can be raised to release the space between the ultrasonic probe 14 and the examination bed, so that the examinee can lie in a suitable position. Then, the position of the ultrasonic probe 14 can be adjusted by the telescopic rod 17 so that it fits against the ultrasonic sound guide pad 1.

[0038] The above descriptions are merely embodiments of the present invention, and common knowledge regarding specific technical solutions or characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
