Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a safe compression system on an X-ray breast machine. Background Art

[0002] The existing X-ray mammography equipment is that medical staff control the lifting and lowering movement of the compression device through a foot switch to squeeze the breast of the examinee to improve the quality of X-ray imaging, but it has the following defects:

[0003] 1. Lack of real-time sensing function: Since the existing compression device cannot sense the stress state of the subject's breast and cannot make corresponding adjustments in advance, and the medical staff cannot sense the stress state of the subject's breast and cannot make corresponding operations in advance, the subject's breast is pinched by the compression device and hurts, causing the subject to complain to the medical staff due to the pain, and further causing the subject to fear and resist the detection of X-ray breast machine;

[0004] 2. Blind spot of medical operation: Medical staff take photos outside the shielded room and are not in the same room as the examinee. They cannot perceive pressure changes in real time and cannot respond to emergencies such as power outages, excessive squeezing of the examinee's lesions, and machine failures during the examination.

[0005] 3. Safety hazards: When the subject tries to break free from the compression device due to panic, there is a lack of emergency release mechanism, which puts the subject at risk of secondary injury.

[0006] Therefore, the compression device on the existing X-ray breast machine cannot safely and comfortably squeeze the breast of the subject. The above problems limit the popularization and application of X-ray breast machines. Therefore, the present application provides a safe compression system on an X-ray breast machine to solve the above problems. Summary of the invention

[0007] In order to solve the above problems, the present application provides a safe compression system on an X-ray breast machine, which realizes dual feedback of position and pressure through mechatronic design, realizes dynamic control and manual release functions, so as to improve patient comfort and reduce operation risks. The technical solution is as follows:

[0008] The present application provides a safe compression system on an X-ray breast machine, comprising a compressor assembly, an electric lifting mechanism and a controller, wherein the compressor assembly is used to squeeze the breast of a subject and feed back pressure information; the electric lifting mechanism is connected to the compressor assembly to drive the compressor assembly to move up and down and feed back position information; the controller is used to receive and process position information and pressure information and dynamically adjust the lifting speed of the electric lifting mechanism in real time and control the start and stop according to the collected position information and pressure information.

[0009] For example, in the safe compression system on the X-ray breast machine provided in one embodiment, the electric lifting mechanism includes a DC motor, a potentiometer assembly, a motor mounting seat, a pulley assembly, a screw mounting seat, a ball screw and a screw nut connected in sequence, the compressor assembly is connected to the screw nut, the DC motor drives the ball screw to rotate through the pulley assembly, and converts the rotational motion into linear motion through the screw nut and drives the compressor assembly to lift and lower.

[0010] For example, in the X-ray breast machine safety compression system provided in one embodiment, the potentiometer assembly is coaxially connected to the ball screw, and the real-time position information of the compressor assembly is generated by converting the number of rotations of the ball screw into an electrical signal, and transmitted to the controller for position closed-loop control.

[0011] For example, in the safe compression system on the X-ray breast machine provided in one embodiment, the compressor assembly includes a compressor lifting seat, a compressor bracket, a pressure sensor and a compression plate assembly, the compressor lifting seat is connected to the screw nut, the compressor bracket is hinged to the compressor lifting seat through a pin shaft, and the compression plate assembly is connected to the compressor bracket.

[0012] For example, in the safe compression system on the X-ray breast machine provided in one embodiment, the pressure sensor is arranged at the hinge of the compressor lifting seat and the compressor bracket to detect the compression pressure in real time, and when the compression disk assembly contacts the breast of the subject, the slight rotation between the compressor lifting seat and the compressor bracket triggers the pressure sensor to output a pressure signal, and the pressure signal is judged by the controller through a threshold value and the compression pressure is dynamically adjusted.

[0013] For example, in the safe compression system on the X-ray breast machine provided in one embodiment, the compressor assembly also includes a manual release device arranged between the compression disk assembly and the compressor bracket, which is used to release the compression in an emergency state, and the manual release device includes a spring cover, a compression spring, a manual handle, a slot block and a rotating block connected in sequence, the spring cover is connected to the compressor bracket, the slot block and the rotating block are connected by a movable pin, and the rotating block is connected to the compression disk assembly. By pushing the manual handle to disengage the movable pin from the slot block, the compression spring releases the elastic force to drive the rotating block to drive the compression disk assembly to rotate, thereby realizing mechanical emergency release of compression.

[0014] For example, in the X-ray breast machine safety compression system provided in one embodiment, the controller includes a shell assembly, a CPU board assembly, an input board assembly, a power board assembly, a drive board assembly, an electrical connector and a motherboard assembly. The input board assembly collects position information through the potentiometer assembly and collects pressure information through the pressure sensor. The CPU board assembly processes the collected position information and pressure information and converts the position information into compression amount according to the pressure information. The speed and pressure of the DC motor are controlled in advance according to the changes in the pressure information and the compression amount. The speed of the DC motor is adjusted and the start and stop are controlled through the drive board assembly, thereby realizing real-time dynamic control according to position feedback and pressure feedback.

[0015] For example, in the X-ray breast machine safety compression system provided in one embodiment, the CPU board component of the controller executes the following control logic: controlling the DC motor to run at high speed in the initial compression stage; switching to low speed operation when the pressure sensor feedback value reaches a first threshold; and immediately cutting off the power supply of the DC motor when the pressure sensor feedback value reaches a second threshold or a stop command is received.

[0016] For example, in one embodiment, the X-ray breast machine safe compression system also includes a display for displaying position information and pressure information in real time.

[0017] For example, in one embodiment, the X-ray breast machine safety compression system also includes a mounting frame, a C-shaped arm is provided on the mounting frame, a linear guide rail is provided on the C-shaped arm, the electric lifting mechanism is installed on the C-shaped arm, and the compressor assembly is installed on the linear guide rail and is lifted and lowered along the linear guide rail under the drive of the electric lifting mechanism.

[0018] The beneficial effects of a safe compression system on an X-ray breast machine provided by some embodiments of the present application are as follows:

[0019] 1) The machine tactile perception function of the compression system is realized through a mechatronic solution: the position information of the compressor assembly is mainly fed back through the potentiometer assembly on the electric lifting mechanism, and the pressure information is fed back through the pressure sensor on the compressor assembly. The controller controls the speed and pressure of the DC motor in real time through the position information and pressure information to avoid excessive compression and provide a safe and comfortable experience for the examinee.

[0020] 2) The visual interface assists medical staff in real-time monitoring: The display provides medical staff with position information and pressure information, allowing them to visually perceive the stress state of the subject's breast, so that they can control the lifting and lowering of the compressor assembly in time and improve operational safety.

[0021] 3) Manual release function of the compression assembly: When there is a power outage, excessive squeezing of the patient's lesion, machine failure or other emergencies, the subject can push the manual handle to release the compression of the compression plate assembly on the subject's breast, ensuring rapid emergency response in emergencies and reducing the risk of secondary injury.

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] The present application provides a safe compression system on an X-ray breast machine, such as Figure 1-2 As shown, including:

[0032] The compressor component 2 is used for squeezing the breast of the subject and feeding back pressure information;

[0033] An electric lifting mechanism 1, connected to the compressor assembly 2 to drive the compressor assembly 2 to move up and down and feedback position information;

[0034] The controller 3 is used to receive and process the position information and the pressure information and dynamically adjust the lifting speed of the electric lifting mechanism 1 in real time and control the start and stop according to the collected position information and pressure information.

[0035] After the medical staff steps on the compressor lifting switch, the controller 3 controls the electric lifting mechanism 1 to move linearly, and the electric lifting mechanism 1 drives the compressor assembly 2 to squeeze the breast of the subject. When the medical staff releases the compressor switch or the controller 3 detects that the feedback pressure is ≥20daN, the electric lifting mechanism 1 stops moving, and the medical staff goes outside the shielded room to perform the shooting operation.

[0036] For example, in the X-ray breast machine safety compression system provided in one embodiment, Figure 3As shown, the electric lifting mechanism 1 includes a DC motor 1.1, a potentiometer assembly 1.2, a motor mounting seat 1.3, a pulley assembly 1.4, a screw mounting seat 1.5, a ball screw 1.6 and a screw nut 1.7 connected in sequence, and the compressor assembly 2 is connected to the screw nut 1.7. The DC motor 1.1 converts electrical energy into rotational motion. After being decelerated by the pulley assembly 1.4, the DC motor 1.1 transmits the rotational motion to the ball screw 1.6 through the pulley assembly 1.4 and drives the ball screw 1.6 to rotate. The ball screw 1.6 converts the rotational motion into the linear motion of the screw nut 1.7 and drives the compressor assembly 2 to lift and lower.

[0037] The potentiometer assembly 1.2 is coaxially connected to the ball screw 1.6, and the potentiometer assembly 1.2 converts the number of rotations of the ball screw 1.6 into an electrical signal, generates real-time position information of the compressor assembly 2, and transmits it to the controller 3 for position closed-loop control.

[0038] For example, in the X-ray breast machine safety compression system provided in one embodiment, Figure 4 As shown, the compressor assembly 2 includes a compressor lifting seat 2.1, a compressor bracket 2.2, a pressure sensor 2.10 and a compression plate assembly 2.9. The compressor lifting seat 2.1 is connected to the lead screw nut 1.7 to transmit the linear motion and power of the lead screw nut 1.7. The compressor bracket 2.2 is hinged to the compressor lifting seat 2.1 through a pin shaft 2.11, and the compression plate assembly 2.9 is connected to the compressor bracket 2.2.

[0039] The pressure sensor 2.10 is arranged at the hinge of the compressor lifting seat 2.1 and the compressor bracket 2.2 to detect the compression pressure in real time. When the compression disk assembly 2.9 contacts the breast of the subject, the slight rotation between the compressor lifting seat 2.1 and the compressor bracket 2.2 triggers the pressure sensor 2.10 to output a pressure signal, thereby providing real-time feedback on the pressure information of the subject's breast. The pressure signal is judged by the controller 3 for threshold value and the compression pressure is dynamically adjusted.

[0040] For example, in the X-ray breast machine safety compression system provided in one embodiment, Figure 4As shown, the compressor assembly 2 also includes a manual release device arranged between the compression disk assembly 2.9 and the compressor bracket 2.2, which is used to release compression in an emergency state. The manual release device includes a spring cover plate 2.3, a compression spring 2.4, a manual handle 2.5, a slot block 2.7 and a rotating block 2.8 connected in sequence. The spring cover plate 2.3 is connected to the compressor bracket 2.2, the slot block 2.7 and the rotating block 2.8 are connected through an active bayonet 2.6, and the rotating block 2.8 is connected to the compression disk assembly 2.9. When an emergency occurs, the subject can push the manual handle 2.5 to disengage the active bayonet 2.6 from the slot block 2.7, and the compression spring 2.4 releases the elastic force to drive the rotating block 2.8 to drive the compression disk assembly 2.9 to rotate, thereby releasing the compression disk assembly 2.9 from squeezing the subject's breast, thereby realizing mechanical emergency compression relief.

[0041] For example, in the X-ray breast machine safety compression system provided in one embodiment, Figure 5 As shown, the controller 3 includes a shell component 3.1, a CPU board component 3.2, an input board component 3.3, a power board component 3.4, a drive board component 3.5, an electrical connector 3.6 and a motherboard component 3.7. The input board component 3.3 collects position information through the potentiometer component 1.2, and collects pressure information through the pressure sensor 2.10. The power board component 3.4 provides a DC power supply for the DC motor 1.1. The CPU board component 3.2 processes the collected position information and pressure information and converts the position information into a pressure amount according to the pressure information. The speed and pressure of the DC motor 1.1 are controlled in advance according to the changes in the pressure information and the pressure amount. The speed of the DC motor 1.1 is adjusted and the start and stop are controlled through the drive board component 3.5, thereby realizing real-time dynamic control according to position feedback and pressure feedback.

[0042] Among them, the CPU board component 3.2 of the controller 3 executes the following control logic: in the initial compression stage, the DC motor 1.1 is controlled to run at high speed; when the feedback value of the pressure sensor 2.10 reaches the first threshold value (5daN), it is switched to low-speed operation; when the feedback value of the pressure sensor 2.10 reaches the second threshold value (20daN) or a stop command is received, the power supply of the DC motor 1.1 is immediately cut off.

[0043] For example, in the X-ray breast machine safety compression system provided in one embodiment, Figure 1 As shown, a display 4 is also included for displaying position information and pressure information in real time, so that medical staff can observe data changes for reference.

[0044] For example, in the X-ray breast machine safety compression system provided in one embodiment, Figure 1 As shown, it also includes a mounting frame 5, on which a C-shaped arm 5.1 is provided, and on which a linear guide rail 5.2 is provided. The electric lifting mechanism 1 is installed on the C-shaped arm 5.1, and the compressor assembly 2 is installed on the linear guide rail 5.2 and is lifted and lowered along the linear guide rail 5.1 under the drive of the electric lifting mechanism 1.

[0045] Specifically, the compressor assembly 2 is mounted on the linear guide rail 5.1 and connected to the electric lifting mechanism 1 through screws, the controller 3 is mounted on the rear side of the mounting frame 5, and the display 4 is mounted on the front side of the mounting frame 5 to facilitate medical staff to observe data changes.

[0046] The workflow of the safe compression system on the X-ray breast machine of this application is as follows Figure 6 As shown: the medical staff steps on the compression lifting switch, and the controller 3 performs a power-on self-test to check the position information and pressure information; the controller 3 drives the DC motor 1.1 to start. At this time, the speed of the DC motor 1.1 is relatively fast, which is the fast stage, reducing the waiting time for the medical staff and the examinee; the electric lifting mechanism 1 drives the compressor component 2 to move up and down, and feeds back the position information; the compressor component 2 squeezes the examinee's breast and feeds back the pressure information; when the feedback pressure value reaches 5daN, the controller 3 controls the DC motor 1.1 to decelerate, which is the slow stage, and reserves reaction time for the electric lifting mechanism 1 to stop moving; when the medical staff releases the compressor lifting switch or the controller 3 detects that the feedback pressure is ≥20daN, the controller 3 controls the DC motor 1.1 to stop rotating.

[0047] The safe compression system on the X-ray breast machine of the present application realizes real-time feedback of position and pressure through the potentiometer component and the pressure sensor. The controller accurately controls and dynamically adjusts the motor speed to avoid excessive compression. The compressor component integrates a manual release mechanism to ensure rapid emergency response in sudden situations, which can quickly release the squeezing and reduce the risk of secondary injury. The visual interface assists medical staff in real-time monitoring and improves operational safety. This system solves the problems of patient discomfort and safety hazards caused by the lack of perception function of existing equipment, and has high safety and easy operation.

[0048] Although the implementation scheme of the present application has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes, and it can be fully applicable to various fields suitable for the present application. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present application is not limited to the specific details and the illustrations shown and described herein.
