Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a breast imaging towing device for improving breast imaging effect. Background Art

[0002] The goal of breast imaging technology is to generate clear images of breast tissue using various physical principles to detect abnormalities such as lumps and microcalcifications. This thinning of the breast tissue reduces the attenuation and scattering of X-rays or sound waves, enhancing the contrast between lesions (such as microcalcifications) and surrounding tissue. The Kangda Intercontinental iMM-Nuance digital mammography system uses a thin film tow device that squeezes the breast up and down to stretch the breast, improving imaging quality.

[0003] In the existing technology, although the Kangda Intercontinental iMM-Nuance digital breast X-ray machine can achieve precise traction of the breast root, the parameters need to be preset in advance, and the traction direction cannot be adjusted in time according to the patient's actual situation during the traction process, resulting in the need to adjust the breast position multiple times before achieving the ideal imaging position.

[0004] In summary, how to solve the problem that the aforementioned device cannot be adjusted according to the patient's actual situation during the traction process, resulting in multiple adjustments of the breast position to achieve the ideal imaging position, has become a technical challenge that technicians in this field urgently need to solve. Therefore, it is necessary to propose a breast imaging traction device that improves breast imaging effects. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides a breast imaging towing device that improves the breast imaging effect. The first driving member and the second driving member respectively drive the first threaded rod and the second threaded rod to rotate, and the adsorption plate is driven to move horizontally by the same-direction rotation of the first threaded rod and the second threaded rod, and the adsorption plate is driven to move vertically by the opposite-direction rotation of the first threaded rod and the second threaded rod, so that it can be quickly adjusted according to the breast position of different patients, thereby improving the imaging efficiency of the patient's breast.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A breast imaging towing device for improving breast imaging performance comprises a support platform and a fixed plate, as well as an adjustment system. A telescopic assembly for adjusting the height of the fixed plate is disposed between the support platform and the fixed plate. The fixed plate is provided with a suction assembly for adsorbing the patient's breast, a suction assembly for generating negative pressure suction, an adjustment assembly for adjusting the position of the suction assembly, and a drive assembly for driving the adjustment assembly. Between the adjustment assembly and the suction assembly are a monitoring assembly for monitoring the tension of the suction assembly and a support assembly for supporting the suction assembly.

[0007] The drive assembly includes a controller, a first drive member, a second drive member, and a plurality of fixed blocks. The controller is used to control the operation of the first drive member and the second drive member respectively. The fixed blocks are fixedly connected to the fixed plate. The adjacent fixed blocks on the same horizontal plane are respectively rotatably matched with the first threaded rod and the second threaded rod. The first drive member is fixedly connected to the fixed block adjacent to it. The output shaft of the first drive member near one end of the fixed block passes through the fixed block and is coaxially fixedly connected to the first threaded rod. The second drive member is fixedly connected to the fixed block adjacent to it. The output shaft of the second drive member passes through the fixed block and is coaxially fixedly connected to the second threaded rod. A transmission assembly for transmitting power to the drive assembly is also provided on the fixed plate. The transmission assembly is located between the first threaded rod and the second threaded rod.

[0008] The technical principle of the above scheme is as follows: the operation of the first driving member and the second driving member is controlled respectively by the controller. The output shafts of the first driving member and the second driving member are coaxially connected to the first threaded rod and the second threaded rod respectively, thereby driving the first threaded rod and the second threaded rod to rotate in the same direction and in the opposite direction, thereby adjusting the position of the adsorption component, and realizing accurate adjustment of the position after the adsorption component adsorbs the breast, ensuring that the imaging area is fully exposed. The suction component sucks gas from the adsorption component, so that the patient's breast can fit on the adsorption component, reducing the movement or deformation of the patient's breast. The monitoring component monitors the pulling force of the adsorption component on the breast in real time, thereby reducing the damage to the patient's breast tissue caused by excessive pulling force.

[0009] The above scheme has the following beneficial effects:

[0010] 1. The present invention controls the operation of the first driving member and the second driving member through a controller, thereby controlling the first threaded rod and the second threaded rod to rotate in the same direction or in the opposite direction. The first threaded rod and the second threaded rod are rotated in the same direction to drive the horizontal displacement of the adjustment component, and are rotated in the opposite direction to drive the vertical displacement of the adjustment component. By increasing the displacement range of the adjustment component, the imaging blur or repeated scanning requirements caused by breast position deviation are reduced, thereby greatly improving the clarity of breast imaging and the diagnostic accuracy.

[0011] 2. The present invention utilizes a suction component and an adsorption component to coordinate and apply negative pressure to the mammary gland, tightly adhering to the surface of the adsorption component. This process effectively limits movement or deformation of the mammary gland during imaging, reducing the risk of imaging artifacts caused by voluntary or involuntary movement of the patient.

[0012] 3. The present invention uses a monitoring component to provide real-time feedback of the pulling force data of the adsorption component on the breast, thereby improving the safety of the patient's breast position during adjustment and reducing damage to the patient's breast tissue.

[0013] Furthermore, the transmission assembly includes a first gear positioned between the first and second threaded rods and slidably engaged with the fixed plate. Both the first and second threaded rods mesh with the first gear. A support rod is fixedly connected to the first gear on the side facing away from the fixed plate. A second gear is fixedly connected to the end of the support rod facing away from the first gear. The second gear meshes with the adjustment assembly.

[0014] Beneficial effect: Transmission is performed through the first gear. When the first threaded rod and the second threaded rod rotate in opposite directions, the first gear will be driven to rotate synchronously, thereby driving the second gear to rotate, and then driving the adjustment component to complete the vertical displacement, thereby improving the positioning accuracy of the target area during breast imaging and ensuring that the imaging area is completely exposed and without distortion.

[0015] Furthermore, the adjustment assembly includes a limit frame, a movable frame, and a plurality of limit plates. The limit plates are fixedly connected to the side of the fixed block away from the fixed plate. Each limit plate has a slide groove for the limit frame to slide, and the slide grooves slidably engage with the limit frame. The limit frame has a movable groove for the movable frame to move, and the movable groove slidably engages with the movable frame. A rack is fixedly connected to the movable frame, and the rack meshes with the second gear.

[0016] Beneficial Effects: Through the sliding cooperation of the limit frame and the movable frame, the adjustment assembly achieves dual-degree-of-freedom motion control. The limit frame slides directionally within the guide slot of the limit plate, providing horizontal linear motion. The movable frame slides within the movable slot of the limit frame, forming a vertical adjustment path. Furthermore, the restraint of the limit plate reduces vibration of the limit frame and movable frame during sliding, improving stability.

[0017] Furthermore, the support assembly includes a support frame, which is fixedly connected to the mobile frame, and a side of the support frame away from the mobile frame is fixedly connected to the monitoring assembly.

[0018] Beneficial Effects: The support frame is rigidly attached to the mobile frame, creating a direct path for force transmission. When the adsorption assembly applies tension to the mammary gland, this force is simultaneously transmitted through the support frame to the monitoring assembly, enabling the monitoring assembly to accurately capture the tension data in real time.

[0019] Furthermore, the monitoring component includes a tension sensor, and the controller is used to receive the tension change of the adsorption component monitored by the tension sensor, and the tension sensor is fixedly connected between the support frame and the adsorption component.

[0020] Beneficial effects: The tension sensor is located between the support frame and the adsorption component, which is conducive to real-time monitoring of the tension changes of the adsorption component and reduces the risk of patient injury due to delayed tension monitoring.

[0021] Furthermore, the adsorption component includes an adsorption plate, which is fixedly connected to the tension sensor. The adsorption plate is provided with a cavity and a plurality of adsorption ports, which are all connected to the cavity and the adsorption ports are connected to the suction component.

[0022] Beneficial effects: The patient's breast is adsorbed by the adsorption disk, and negative pressure suction is generated at the adsorption port by the suction component, thereby improving the stability of the patient's breast during the towing process.

[0023] Furthermore, the suction assembly includes a piston cylinder and a rotating disk. The rotating disk is coaxially fixedly connected to the end of the first drive member remote from the fixed block. A push rod is eccentrically hinged to the rotating disk. The piston cylinder is fixedly connected to the fixed plate. The piston cylinder has an air inlet and an air outlet. Both the air inlet and the air outlet are connected to a one-way valve. The air inlet is connected to the temporary storage assembly. A piston head is slidably fitted within the piston cylinder. The end of the piston head remote from the air inlet is hinged to the push rod.

[0024] Beneficial effect: When the first driving member drives the rotating disk to rotate, the eccentrically hinged push rod converts the rotational motion of the rotating disk into reciprocating linear motion of the piston head in the piston cylinder, thereby improving the efficiency of gas transmission, continuously and stably sucking air into the temporary storage component, and generating negative pressure suction.

[0025] Furthermore, the temporary storage component includes a negative pressure box, which is connected to the air inlet. A vent is opened on the negative pressure box, and a solenoid valve is fixedly connected to the vent. The controller is used to control the opening and closing of the solenoid valve. The vent is connected to an adsorption pipe, and the end of the adsorption pipe away from the vent is connected to the cavity.

[0026] Beneficial effect: The negative pressure box is connected to the cavity through the adsorption pipe, and the negative pressure suction of the negative pressure box to the cavity can be continuous and stable, reducing the possibility of the patient's breast falling off during the dragging process.

[0027] Furthermore, the telescopic assembly includes a plurality of telescopic parts, the controller is used to control the operation of the telescopic parts, the telescopic parts are fixedly connected to the support platform, and the output shafts of the telescopic parts are fixedly connected to the fixed plate.

[0028] Beneficial effect: The height of the fixed plate can be adjusted by controlling the extension and retraction of the telescopic member through the controller, so that the adsorption plate can be in a suitable position to adsorb the patient's breast, thereby improving the operation efficiency.

[0029] Furthermore, the adjustment system includes a data receiving module and a control module. The data receiving module is configured to receive the suction plate tension data monitored by the controller and transmit the tension data to the control module. The control module is configured to control the controller based on the tension data transmitted by the data receiving module. When the tension data is between 15N and 18N, the control module controls the solenoid valve to close via the controller. When the tension data exceeds 18N, the control module controls the first and second drive members to close via the controller.

[0030] Beneficial Effects: By adjusting the system to automate control of the device, when the pulling force reaches 15N, the system automatically closes the solenoid valve to interrupt the negative pressure supply, preventing microvascular rupture or nerve compression caused by continued traction on breast tissue. When the pulling force exceeds 18N, the first and second driving elements are immediately controlled to shut down, preventing breast tissue damage caused by strong pulling force.

[0031] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following is further described in detail through specific implementation methods:

[0039] Example 1:

[0040] As attached Figure 1The figure shows a breast imaging towing device for improving breast imaging. The device comprises a support platform 1 and a fixed plate 2, as well as an adjustment system. A telescopic assembly for adjusting the height of the fixed plate 2 is disposed between the support platform 1 and the fixed plate 2. The fixed plate 2 is equipped with a suction assembly for adsorbing the patient's breast, a suction assembly for generating negative pressure suction, an adjustment assembly for adjusting the position of the suction assembly, and a drive assembly for driving the adjustment assembly. Between the adjustment assembly and the suction assembly are a monitoring assembly for monitoring the tension of the suction assembly and a support assembly for supporting the suction assembly.

[0041] Specific, combined Figure 2 As shown, the drive assembly includes a controller, a first drive member, a second drive member, and several fixed blocks 3. In this embodiment, the first drive member is a double-headed motor 7, and the second drive member is a drive motor 4. The controller is used to control the operation of the double-headed motor 7 and the drive motor 4, respectively. The fixed blocks 3 are bolted to the fixed plate 2. A first threaded rod 6 and a second threaded rod 17 are respectively rotatably engaged between adjacent fixed blocks 3 on the same horizontal plane. The double-headed motor 7 is bolted to the adjacent fixed block 3. The output shaft of the double-headed motor 7 near one end of the fixed block 3 passes through the fixed block 3 and is coaxially bolted to the first threaded rod 6. The drive motor 4 is bolted to the adjacent fixed block 3. The output shaft of the drive motor 4 passes through the fixed block 3 and is coaxially bolted to the second threaded rod 17. The fixed plate 2 also has a transmission assembly for transmitting power to the drive assembly. The transmission assembly is located between the first threaded rod 6 and the second threaded rod 17. The transmission assembly includes a first gear 19, which is located between the first threaded rod 6 and the second threaded rod 17 and slides with the fixed plate 2. The first threaded rod 6 and the second threaded rod 17 are both engaged with the first gear 19. The first gear 19 is fixedly connected to the support rod on the side away from the fixing plate 2 with screws, and the end of the support rod away from the first gear 19 is fixedly connected to the second gear 14 with screws, and the second gear 14 is engaged with the adjustment assembly.

[0042] When the controller controls the double-headed motor 7 to start, the double-headed motor 7 will drive the first threaded rod 6 to rotate. When the controller controls the drive motor 4 to start, the drive motor 4 will drive the second threaded rod 17 to rotate. When the first threaded rod 6 and the second threaded rod 17 rotate in the same direction, because the first threaded rod 6 and the second threaded rod 17 are both engaged with the first gear 19, the first gear 19 will slide horizontally along the fixed plate 2 as the first threaded rod 6 and the second threaded rod 17 rotate. At this time, the first gear 19 will not rotate. When the first threaded rod 6 and the second threaded rod 17 rotate in opposite directions, the first gear 19 will rotate due to the opposite rotation of the first threaded rod 6 and the second threaded rod 17. The rotation of the first gear 19 will then drive the rotation of the second gear 14, and the rotation of the second gear 14 will drive the vertical movement of the adjustment assembly.

[0043] Specifically, the adjustment assembly includes a limit frame 9, a movable frame 12, and several limit plates 5. The limit plates 5 are bolted to the side of the fixed block 3 away from the fixed plate 2. Each limit plate 5 has a slot for the limit frame 9 to slide, and the slots slidably engage with the limit frame 9. The limit frame 9 has a movable slot for the movable frame 12 to move, and the movable slots slidably engage with the movable frame 12. A rack 13 is screwed to the movable frame 12, and the rack 13 meshes with a second gear 14.

[0044] Because the rack 13 is meshed with the second gear 14, when the second gear 14 rotates, the second gear 14 drives the rack 13 to move vertically. The vertical movement of the rack 13 drives the movable frame 12 to move vertically along the movable groove, thereby adjusting the vertical position of the adsorption assembly. When the first gear 19 slides along the fixed plate 2 and the first gear 19 does not rotate, the second gear 14 drives the rack 13 to slide horizontally, thereby driving the limit frame 9 to slide horizontally along the slide groove through the rack 13, thereby adjusting the horizontal position of the adsorption assembly.

[0045] Specific, combined Figure 3 As shown, the support assembly includes a support frame 11, which is bolted to a mobile frame 12. The side of the support frame 11 away from the mobile frame 12 is screwed to the monitoring assembly. The monitoring assembly includes a tension sensor 15. The controller is used to receive the tension changes of the adsorption assembly monitored by the tension sensor 15. The tension sensor 15 is screwed between the support frame 11 and the adsorption assembly. The adsorption assembly includes an adsorption plate 16, which is screwed to the tension sensor 15. The adsorption plate 16 has a cavity 22 and a plurality of adsorption ports 23. The adsorption ports 23 are all connected to the cavity 22, and the adsorption ports 23 are connected to the suction assembly.

[0046] The support frame 11 is fixedly connected to the tension sensor 15 by screws, and the tension sensor 15 is fixedly connected to the adsorption plate 16 by screws. At this time, when the support frame 11 moves with the movable frame 12, the tension applied to the adsorption plate 16 can be monitored by the tension sensor 15, and then the tension of the adsorption plate 16 on the patient's breast can be judged.

[0047] Specific, combined Figure 4 As shown, the suction assembly includes a piston cylinder 10 and a rotating disk 24. Rotating disk 24 is coaxially bolted to the end of the double-headed motor 7 away from the fixed block 3. A push rod 8 is eccentrically hinged to rotating disk 24. The piston cylinder 10 is bolted to the fixed plate 2. It has an air inlet and an air outlet, both of which are connected to one-way valves. The air inlet is connected to the temporary storage assembly. A piston head 21 slides within the piston cylinder 10, and the end of the piston head 21 away from the air inlet is hinged to the push rod 8.

[0048] When the double-headed motor 7 is running, the double-headed motor 7 will simultaneously drive the rotating disk 24 to rotate. As the rotating disk 24 rotates, the rotating disk 24 will drive the push rod 8 to continuously reciprocate, thereby driving the piston head 21 to slide back and forth in the piston cylinder 10. At this time, the air inlet of the piston head 21 will continuously draw gas from the temporary storage assembly, forming a negative pressure environment.

[0049] Specifically, the temporary storage component includes a negative pressure box 20, which is connected to the air inlet. A vent is opened on the negative pressure box 20, and a solenoid valve is fixedly connected to the vent by screws. The controller is used to control the opening and closing of the solenoid valve. The vent is connected to an adsorption pipe, and the end of the adsorption pipe away from the vent is connected to the cavity 22.

[0050] As the piston head 21 continues to slide within the piston cylinder 10, the air pressure within the negative pressure box 20 will continue to decrease. When the patient's breast needs to be adsorbed, the controller can be used to control the solenoid valve to open. At this time, the gas in the adsorption disk 16 will enter the negative pressure box 20 through the adsorption port 23 and the cavity 22. At this time, the patient's breast will be adsorbed on the adsorption disk 16 under the action of the negative pressure suction. Thus, it moves with the movement of the mobile frame 12, facilitating subsequent imaging of the patient's breast.

[0051] The specific implementation process is as follows: Figure 1 and Figure 2 For example, first, the medical staff can control the operation of the double-headed motor 7 and the drive motor 4 through the controller, and then drive the rotation of the first threaded rod 6 and the second threaded rod 17 through the operation of the double-headed motor 7 and the drive motor 4.

[0052] The first threaded rod 6 and the second threaded rod 17 rotate in the same direction to adjust the position of the first gear 19 horizontally, thereby adjusting the horizontal positions of the movable frame 12 and the support frame 11 so that the adsorption plate 16 can be aligned with the root of the patient's breast.

[0053] Combine Figure 3 and Figure 4 As shown, as the double-headed motor 7 runs, the piston cylinder 10 continuously draws air from the negative pressure box 20, thereby forming a negative pressure environment in the negative pressure box 20. The medical staff can then control the solenoid valve to open through the controller. At this time, the negative pressure box 20 is connected to the cavity 22 and the adsorption port 23 through the adsorption pipe. The patient's breast can then be stably adsorbed on the adsorption disk 16 under the action of the negative pressure suction of the negative pressure box 20. Since the volume of the negative pressure box 20 is ≥5 times the volume of the cavity 22, the negative pressure suction generated by the negative pressure box 20 is sufficient and the patient's breast will not fall off.

[0054] Then, the medical staff can control the double-headed motor 7 and the drive motor 4 to reverse through the controller according to the patient's physical condition. The reversal of the double-headed motor 7 and the drive motor 4 drives the first threaded rod 6 and the second threaded rod 17 to reverse, thereby driving the first gear 19 and the second gear 14 to rotate, and then driving the rack 13 to move vertically. At this time, the movable frame 12 can slide vertically along the movable groove, thereby adjusting the vertical position of the adsorption plate 16, stretching the patient's breast, and improving the imaging effect of the patient's breast.

[0055] During the process of stretching the patient's breast, the medical staff can monitor the tension received by the patient's breast in real time through the tension sensor 15, thereby reducing the situation where the patient's breast is overstretched and causes skin damage.

[0056] The present invention adjusts the horizontal displacement of the adsorption plate 16 by rotating the first and second threaded rods 6 and 17 in the same direction, and adjusts the vertical displacement of the adsorption plate 16 by rotating the first and second threaded rods 6 and 17 in opposite directions, thereby vertically stretching the patient's breast. The stretching position can be freely adjusted according to the patient's breast condition, reducing the need for multiple adjustments and adsorptions to the breast, thereby improving imaging quality.

[0057] Example 2:

[0058] like Figure 1 As shown, the difference from the above embodiment is that the telescopic assembly includes several telescopic parts. In this embodiment, the telescopic part is selected as an electric telescopic rod 18. The controller is used to control the operation of the electric telescopic rod 18. The electric telescopic rod 18 is fixedly connected to the support platform 1 with bolts, and the output shaft of the electric telescopic rod 18 is fixedly connected to the fixing plate 2 with screws.

[0059] The specific implementation process is as follows: medical staff can control the electric telescopic rod 18 through the controller to adjust the position of the fixing plate 2, thereby preliminarily aligning the adsorption disk 16 with the patient's breast position, further improving the efficiency of adsorption and imaging.

[0060] Example 3:

[0061] like Figure 5 As shown, the difference from the above embodiment is that the adjustment system includes a data receiving module and a control module. The data receiving module is used to receive the tension data of the suction plate 16 monitored by the controller and transmit the tension data to the control module. The control module is used to control the controller according to the tension data transmitted by the data receiving module.

[0062] When the tension data is between 15N-18N, the control module controls the solenoid valve to close through the controller. When the tension data exceeds 18N, the control module controls the double-headed motor 7 and the drive motor 4 to close through the controller.

[0063] The specific implementation process is as follows: The data receiving module continuously receives the tension data of the suction plate 16 monitored by the tension sensor 15 through the controller. Medical personnel can preset the tension threshold through the control module. When the tension of the suction plate 16 on the patient's breast exceeds 15N, the control module controls the solenoid valve to close, disconnecting the negative pressure tank 20 from the suction pipe, blocking the negative pressure supply. At this time, the suction force between the patient's breast and the suction plate 16 is reduced, thereby protecting the patient's breast.

[0064] When the pulling force of the suction plate 16 on the patient's breast exceeds 18N, the control module will control the double-headed motor 7 and the drive motor 4 to shut down through the controller. At this time, the first threaded rod 6 and the second threaded rod 17 both stop rotating, and the position of the suction plate 16 is locked, thereby avoiding further stretching of the patient's breast and causing damage to the breast tissue.

[0065] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
