Description

Technical Field

[0001] This invention relates to the field of full-ring SPECT-CT equipment technology, specifically a probe mounting and dismounting device and method for full-ring SPECT-CT equipment. Background Technology

[0002] The full-ring SPECT-CT system is a gamma-ray detection device used for nuclear medicine imaging. Its core structure consists of nine probes and a circular mounting base. The nine probes are evenly distributed along the circumference of the mounting base and are all fixed in place by screws. Each probe consists of integrated front-end electronic circuitry, a photomultiplier tube sensor, a scintillation crystal, a collimator, and a radiation shielding device. These components work together to detect gamma rays and convert the signal. When it is necessary to replace the probes on the circular mounting base, the collimator and radiation shielding device must have high radiation blocking capabilities. These components are typically made of high-density lead or tungsten metal, which significantly increases the overall weight of a single probe. This not only requires more manpower and reduces operational efficiency during probe disassembly and installation, but also poses a safety hazard due to the risk of injury from handling heavy objects or assembly imbalances.

[0015] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] In the description of this invention, it should be understood that the terms "length", "middle", "upper", "lower", "left", "right", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0017] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "assembly," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0018] A probe mounting and dismounting device for a full-circle SPECT-CT device includes a lifting support frame 1, a driver 2, an L-shaped bracket 3, a connecting block 4, and a probe carrying assembly 5. The driver 2 is mounted on the lifting support frame 1, the L-shaped bracket 3 is slidably mounted on the lifting support frame 1, the connecting block 4 is fixed to the rear side of the L-shaped bracket 3, the driving end of the driver 2 is connected to the connecting block 4, and the probe carrying assembly 5 is disposed on the top surface of the L-shaped bracket 3. The probe carrying assembly 5 is used to carry the probe 61 of the full-circle SPECT-CT device 6.

[0019] This solution provides a probe mounting and dismounting device for a full-ring SPECT-CT device, such as... Figure 1-2As shown, in this embodiment, the actuator 2 is a hydraulic cylinder. The device also includes a first controller 7, which is electrically connected to the actuator 2. The operator presets the highest and lowest positions for probe loading and unloading on the first controller 7, and this information is synchronously transmitted to the actuator 2 for precise control. The full-ring SPECT-CT device 6 includes nine probes 61, a circular mounting base 62, a motor (not shown in the figure) for driving the circular mounting base 62 to rotate, and a second controller. The nine probes 61 are evenly distributed on the circular mounting base 62 along the circumference. The second controller is electrically connected to the motor, and the highest position for probe loading and unloading is also preset on the second controller. When it is necessary to remove a set of probes 61 from the annular mounting base 62, firstly, the motor receives a command from the second controller to drive the annular mounting base 62 to rotate, precisely rotating the probe 61 to be removed to the highest position for probe loading and unloading. Then, the operator pushes the lifting support frame 1 so that its bottom can enter the gap between the bottom of the full-ring SPECT-CT equipment 6 and the ground, achieving a tight fit between the probe loading and unloading device and the full-ring SPECT equipment 6, minimizing the operating space and significantly saving space in the hospital's nuclear medicine equipment examination room. Simultaneously, the L-shaped bracket 3 can extend into the inner cavity of the annular mounting base 62, accurately aligning the probe carrying assembly 5 on the L-shaped bracket 3 directly below the probe 61 to be removed, ensuring sufficient space for movement for the probe carrying assembly 5. Next, the driver 2 is activated. The driver 2 receives a feedback signal from the first controller 7 and drives the L-shaped bracket 3 to slide upwards along the lifting support frame 1, moving the probe carrying assembly 5 to the highest position for probe loading and unloading. At this point, the probe carrying assembly 5 can support the probe 61 to be removed. Then, the operator manually removes the fixing screws between the probe 61 to be removed and the annular mounting base 62. Subsequently, the actuator 2 receives the feedback signal from the first controller 7 again, driving the L-shaped bracket 3 to slide downwards along the lifting support frame 1, so that the probe carrying assembly 5 carrying the removed probe 61 moves to the lowest position for probe loading and unloading. Finally, the operator moves the probe loading and unloading device out of the area of ​​the full-ring SPECT-CT equipment 6, thus completing the removal of the probe 61 of the full-ring SPECT-CT equipment 6.

[0020] In this solution, the installation and removal of the probe 61 of the full-ring SPECT-CT equipment 6 are achieved through the coordinated operation of the lifting support frame 1, the driver 2, the L-shaped bracket 3, the connecting block 4, and the probe carrying assembly 5. During the installation and removal of the probe 61, the probe carrying assembly 5 installed on the L-shaped bracket 3 can stably support the probe 61, which not only eliminates the need for multiple operators to manually lift the probe for extended periods, reducing labor costs and improving loading and unloading efficiency, but also avoids accidental injury to personnel due to heavy object handling or assembly imbalance, ensuring operational safety.

[0021] Preferably, the probe support assembly 5 includes a lifting base plate 51, an aluminum support seat 52, and several buffer pads 53; the lifting base plate 51 is installed on the top surface of the L-shaped bracket 3, the aluminum support seat 52 is installed on the lifting base plate 51, and the buffer pads 53 are evenly distributed on the left and right inner sides of the aluminum support seat 52.

[0022] In this embodiment, as Figure 3 As shown, the lifting base plate 51 provides reliable support for the entire probe support assembly 5. The aluminum support base 52 is made of lightweight, high-strength aluminum, which effectively reduces the overall weight of the probe support assembly 5 while ensuring structural strength to stably support the probe 61. Since the buffer pads 53 are evenly distributed on the left and right inner sides of the aluminum support base 52, the elastic deformation of the buffer pads 53 absorbs the impact force during the placement of the probe 61, avoiding rigid collisions between the probe 61 and the aluminum support base 52, and preventing damage to the precision electronic components inside the probe 61 due to mechanical impact.

[0023] Preferably, the aluminum support base 52 includes a base plate 521, two first left upright plates 522, two second left upright plates 523, two first right upright plates 524, two second right upright plates 525, three left connecting plates 526, three right connecting plates 527, a left support plate 528, and a right support plate 529. The base plate 521 is mounted on the top surface of the lifting base plate 51. Two first left upright plates 522 and two second left upright plates 523 are mounted on the left side of the base plate 521. The two first left upright plates 522 are symmetrically distributed along the front-back direction of the base plate 521 on both sides. The two second left upright plates 523 are located between the two first left upright plates 522 and are symmetrically distributed front-back. One first left upright plate 522 and its adjacent second left upright plate 523, two second left upright plates 523, and another first left upright plate 522 and its adjacent second left upright plate 523 are respectively connected by the corresponding left connecting plate 526. The front and rear ends of the left support plate 528 are respectively connected to the corresponding first left upright plate 522, and the right side of the left support plate 528 is connected to the two second left upright plates 523. Two first right upright plates 524 and two second right upright plates 525 are installed on the right side of the base plate 521. The two first right upright plates 524 are symmetrically distributed along the front-back direction of the base plate 521 on both sides of its edge. The two second right upright plates 525 are located between the two first right upright plates 524 and are symmetrically distributed front-back. One first right upright plate 524 is connected to its adjacent second right upright plate 525, two second right upright plates 525, and another first right upright plate 524 is connected to its adjacent second right upright plate 525 through corresponding right connecting plates 527. The front and rear ends of the right support plate 529 are respectively connected to the corresponding first right upright plate 524, and the left side of the right support plate 529 is connected to the two second right upright plates 525. The left support plate 528 and the right support plate 529 are both inclined and are symmetrically distributed. The buffer pads 53 are evenly distributed on the right side of the left support plate 528 and the left side of the right support plate 529.

[0024] In this embodiment, as Figure 3 As shown, the combined frame structure of the base plate 521, the first left upright plate 522, the second left upright plate 523, the first right upright plate 524, the second right upright plate 525, the left connecting plate 526, and the right connecting plate 527, using lightweight aluminum, enhances the overall structural strength and deformation resistance of the aluminum support 52 through the rigid connection of each component. It also avoids local stress concentration by distributing the force, thus stably supporting the weight of the probe 61 and resisting external impacts during loading and unloading. The inclined symmetrical design of the left support plate 528 and the right support plate 529 allows for precise adaptation to the outer contour of the probe 61, thereby improving the stability of the probe 61 under load.

[0025] Preferably, the lifting support frame 1 includes a vertical guide frame 11 and a concave base 12. The concave base 12 is fixed to the bottom of the vertical guide frame 11, and the opening of the concave base 12 faces forward. The L-shaped bracket 3 is slidably mounted on the vertical guide frame 11. In this embodiment, as shown... Figure 1 As shown, when the operator pushes the lifting support frame 1 towards the full-ring SPECT-CT device 6, the concave base 12 can accurately insert into the gap between the bottom of the full-ring SPECT-CT device 6 and the ground, ensuring a tight fit between the probe mounting / unmounting device and the full-ring SPECT device 6, providing a precise positional reference for subsequent probe 61 mounting / unmounting operations. The vertical guide frame 11 provides vertical guidance and constraint for the L-shaped bracket 3, ensuring its stable vertical movement.

[0026] Preferably, it further includes a first controller 7, which is mounted on the bottom of the vertical guide frame 11 and is electrically connected to the driver 2. In this embodiment, as... Figure 1 As shown, the first controller 7 is configured to adjust the operating status of the driver 2 in real time, thereby achieving precise control of the lifting speed and position of the L-shaped bracket 3.

[0027] Preferably, it also includes a control button box 8, which is mounted on the vertical guide frame 11 and located above the first controller 7. The control button box 8 is electrically connected to the first controller 7. In this embodiment, as... Figure 1 As shown, the control button box 8 is configured to receive manual commands from the operator, such as lifting commands or start / stop commands. The manual commands are transmitted to the first controller 7, which processes them and then sends corresponding action signals to the driver 2.

[0028] Another aspect of this application provides a method for assembling and disassembling a probe for a full-ring SPECT-CT device, the method comprising a probe disassembly step S1 and a probe installation step S2 for the full-ring SPECT-CT device; Specifically, the probe disassembly step S1 of the full-ring SPECT-CT device includes the following sub-steps: Step S11: The first controller 7 presets the highest and lowest positions for probe loading and unloading; Step S12: By driving the circular mounting base plate 62 of the full-ring SPECT-CT device 6 to rotate, any group of probes 61 to be removed from the full-ring SPECT-CT device 6 is rotated to the highest position point for probe loading and unloading. Step S13: Push the probe mounting and dismounting device of the full-ring SPECT-CT equipment to the full-ring SPECT-CT equipment 6, so that the bottom of the lifting support frame 1 is inserted into the gap between the bottom of the full-ring SPECT-CT equipment 6 and the ground, and the L-shaped bracket 3 extends into the inner circular cavity of the annular mounting base plate 62. Step S14: Start the driver 2, which receives the feedback signal from the first controller 7 and drives the L-shaped bracket 3 to slide upward along the lifting support frame 1, so that the probe carrying assembly 5 moves to the highest position point for probe loading and unloading, so as to carry the probe 61 to be disassembled. Step S15: Manually remove the fixing screws between the probe 61 to be disassembled and the annular mounting base plate 62; Step S16: Restart the driver 2, which receives the feedback signal from the first controller 7 and drives the L-shaped bracket 3 to slide down along the lifting support frame 1, so that the probe carrying assembly 5 carrying the disassembled probe 61 moves to the lowest position point for probe loading and unloading. Step S17: Remove the probe mounting and dismounting device of the full-ring SPECT-CT equipment from the area of ​​the full-ring SPECT-CT equipment 6 to complete the disassembly of the probe 61. Step S18: By driving the circular mounting base plate 62 of the full-ring SPECT-CT device 6 to rotate, the next set of probes 61 to be removed will be rotated to the highest position for probe loading and unloading. Steps S13 to S17 will be repeated until the removal of all probes 61 to be removed is completed.

[0029] This solution provides a method for assembling and disassembling probes in a full-ring SPECT-CT device. By executing steps S11 to S18, all probes 61 to be disassembled in the full-ring SPECT-CT device can be disassembled.

[0030] Preferably, the probe installation step S2 of the full-ring SPECT-CT device specifically includes the following sub-steps: Step S21: The first controller 7 presets the highest and lowest positions for probe loading and unloading; Step S22: By driving the circular mounting base 62 of the full-ring SPECT-CT device 6 to rotate, any probe mounting position on the circular mounting base 62 is rotated to the highest position point for probe loading and unloading. Step S23: Push the probe mounting and dismounting device of the full-ring SPECT-CT equipment to the full-ring SPECT-CT equipment 6, so that the bottom of the lifting support frame 1 is inserted into the gap between the bottom of the full-ring SPECT-CT equipment 6 and the ground, and the L-shaped bracket 3 extends into the inner cavity of the annular mounting base plate 62. Step S24: Start the driver 2, which receives the feedback signal from the first controller 7 and drives the L-shaped bracket 3 to slide upward along the lifting support frame 1, so that the probe carrying assembly 5, which is pre-loaded with the probe 61 to be installed, moves to the highest position point for probe loading and unloading. Step S25: Fix the probe 61 to be installed to the corresponding probe mounting position on the annular mounting base plate 62 with screws; Step S26: Restart the driver 2, which receives the feedback signal from the first controller 7 and drives the L-shaped bracket 3 to slide down along the lifting support frame 1, so that the empty probe carrying assembly 5 moves to the lowest position point for probe loading and unloading. Step S27: Remove the probe mounting and dismounting device of the full-ring SPECT-CT equipment from the area 6 of the full-ring SPECT-CT equipment to complete the installation of the probe 61. Step S28: By driving the circular mounting base 62 of the full-ring SPECT-CT device 6 to rotate, the next probe mounting position is rotated to the highest position point for probe loading and unloading. Repeat steps S23 to S27 until the installation of all probes 61 to be installed is completed.
