Abstract
Description
Technical Field
[0001] This invention relates to the field of radiotherapy monitoring technology, specifically to a device for real-time monitoring of the radiotherapy process. Background Technology
[0002] Radiation therapy for tumors is a local treatment method that uses radiation to treat tumors. Radiation includes alpha, beta, and gamma rays produced by radioactive isotopes, as well as X-rays, electron beams, proton beams, and other particle beams produced by various X-ray therapy machines or accelerators. Approximately 70% of cancer patients require radiation therapy during cancer treatment, and about 40% of cancers can be cured with radiation therapy. The role and importance of radiation therapy in tumor treatment is increasingly prominent, and it has become one of the main methods for treating malignant tumors. With the help of advancements in CT imaging and computer technology, current radiation therapy techniques have evolved from two-dimensional to three-dimensional and four-dimensional radiation therapy. Radiation dose distribution has also evolved from point dose to volumetric dose distribution, and dose adjustment within volumetric dose distribution. Current mainstream radiation therapy techniques include stereotactic radiotherapy and stereotactic radiosurgery. Stereotactic radiotherapy includes three-dimensional conformal radiotherapy and three-dimensional conformal intensity-modulated radiotherapy (IMRT). Stereotactic radiosurgery includes X-Knife, Gamma Knife, and CyberKnife. These devices all fall under the category of stereotactic radiotherapy, characterized by three-dimensional, small-field, focused, fractionated, and high-dose irradiation. It requires higher precision in targeting and faster dose decay outside the target area. The efficacy of radiotherapy depends on radiosensitivity. Different tissues and organs, as well as various tumor tissues, exhibit varying degrees of change in response after irradiation. Radiosensitivity is related to the tumor cell proliferation cycle and pathological grade; that is, actively proliferating cells are more sensitive than non-proliferating cells, and the higher the degree of cell differentiation, the lower the radiosensitivity, and vice versa.
[0003] During radiotherapy, the patient is located in the treatment room, while the doctor is located in the observation room, operating the radiotherapy machine to administer the treatment. The doctor monitors the patient's condition in real time via a monitor. If the patient experiences discomfort that causes excessive movement, the doctor needs to stop the treatment and enter the treatment room to check. In the chaos, the monitor may be bumped, and existing monitors generally lack collision protection, making them susceptible to damage. Therefore, a device for real-time monitoring of the radiotherapy process is needed to address these issues. Summary of the Invention
[0004] The purpose of this invention is to provide a device for real-time monitoring of the radiotherapy process, which has the advantage of providing anti-collision protection for radiotherapy monitoring equipment and solves the problem that existing radiotherapy monitoring equipment is easily damaged after being impacted.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a device for real-time monitoring of radiotherapy process, comprising a monitoring display for real-time monitoring of the internal condition of the treatment room and a support leg for supporting the monitoring display. The back of the monitoring display has two symmetrically distributed movable slots, and a movable plate is slidably installed inside the movable slots. The bottom end of the movable plate is fixedly connected to a movable rod that slides through the bottom side wall of the monitoring display, and the bottom end of the movable rod is fixedly connected to a collision rod that is perpendicular to the movable rod.
[0006] The movable plate is provided with a sliding plate that slides vertically, and a pressing plate is fixedly connected to the bottom end of the movable plate on the side near the back of the monitoring display. A buffer spring is fixedly connected between the sides of the sliding plate and the pressing plate that are close to each other, and a second blocking block is fixedly connected to the bottom end of the sliding plate near the back of the monitoring display. A support rod is rotatably installed on the back of the monitoring display, and a first blocking block is fixedly installed at the bottom end of the support rod on the side near the sliding plate to block the second blocking block.
[0007] By adopting the above technical solution, when the monitoring monitor is impacted and tilted, the impact rod contacts the desktop and is squeezed. The impact rod pushes the movable rod, causing the movable rod to push the movable plate to slide inside the movable groove. Due to the obstruction of the first and second blocking blocks, when the movable plate slides inside the movable groove, it drives the compression plate to squeeze the buffer spring. The elastic force of the buffer spring protects the entire monitoring monitor, allowing the monitoring monitor to automatically reset as much as possible through the elastic force of the buffer spring. This provides initial buffer protection for the monitoring monitor.
[0008] Furthermore, the movable plate has a groove on the side near the back of the monitoring display for the slide plate to slide stably, and both the slide plate and the groove have a T-shaped cross-section when viewed from above.
[0009] By adopting the above technical solution, the T-shaped arrangement of the slide plate and the chute can ensure the stability when the movable plate moves upward along the movable chute.
[0010] Furthermore, a limiting rod is fixedly connected to the bottom end of the slide plate, and the limiting rod is slidably connected to the extrusion plate. The buffer spring is sleeved on the outside of the limiting rod, and an anti-detachment block is fixedly connected to the bottom end of the limiting rod to prevent the limiting rod from detaching from the extrusion plate.
[0011] By adopting the above technical solution, the limiting rod can ensure the stability of the skateboard when it moves on the moving board, and the anti-detachment block can prevent the skateboard from detaching from the squeezing plate during subsequent movements.
[0012] Furthermore, the bottom ends of both the extrusion plate and the support rod are wedge-shaped, and the extrusion plate and the bottom end of the support rod are in sliding contact. An movable block located above the slide plate is slidably installed inside the movable groove, and a connecting rod is hinged between the top end of the movable block and the support rod.
[0013] By adopting the above technical solution, when the pressing plate on the movable plate contacts the end of the support rod, since both the bottom ends of the pressing plate and the support rod are wedge-shaped, the pressing plate will push the support rod, causing the support rod to rotate slightly. This allows the first blocking block to disengage from the blocking state of the second blocking block. At this time, the elastic force of the buffer spring is released instantaneously, pushing the slide plate to move quickly. The slide plate then pushes the movable block, causing the movable block to push the connecting rod. The connecting rod then pushes the support rod, causing the support rod to unfold. This provides support for the entire monitoring display, preventing it from falling directly onto the table and damaging the monitoring display.
[0014] Furthermore, a limiting block two is fixedly connected to the side of the movable block near the front of the monitoring display, and a limiting groove two is provided on the inner side of the monitoring display near the movable groove for the limiting block two to slide.
[0015] By adopting the above technical solution, the sliding of the second limiting block inside the second limiting groove can ensure the stability of the moving block when it moves in the vertical direction.
[0016] Furthermore, slots are provided on both sides of the support rod, and two sets of insert plates that match the slots are slidably installed on the back of the monitoring display. A rectangular groove is provided on the insert plate that penetrates its body, and a drive component that cooperates with the rectangular groove is provided on the side of the movable plate near the back of the monitoring display.
[0017] Furthermore, the drive assembly includes a fixed rod that is fixedly installed on the side of the movable plate near the back of the monitoring display, and a drive plate that is perpendicular to the fixed rod is fixedly connected to the end of the fixed rod, and the top of the drive plate is wedge-shaped.
[0018] By adopting the above technical solution, when the collision rod pushes the movable rod, and the movable rod pushes the movable plate to slide inside the movable slot, providing initial buffer protection for the monitoring display, in order to avoid the situation where the support rod rotates due to the monitoring display tipping over, causing the first blocking block to prematurely disengage from the blocking state of the second blocking block, the insertion plate inserted into the slot can effectively avoid the above situation. Furthermore, when the movable plate moves a certain distance and the elastic force of the buffer spring cannot reset the monitoring display, the movable plate drives the fixed rod, and the fixed rod drives the drive plate. Through the cooperation of the drive plate and the rectangular slot, the insertion plate can be driven to move away from the slot until the insertion plate is completely disengaged from the slot. Then, the contact between the pressing plate and the end of the support rod causes the support rod to rotate, and then the above-mentioned operation of rotating and unfolding the support rod is performed, providing support and protection for the monitoring display.
[0019] Furthermore, a limiting block is fixedly installed on the insert plate, and a limiting groove is provided on the back of the monitoring display for the limiting block to slide.
[0020] By adopting the above technical solution, the sliding of the limiting block 1 inside the limiting groove 1 can ensure the stability of the insert plate when it moves laterally.
[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0022] This invention uses the contact between the collision rod and the tabletop to push the movable rod, which in turn pushes the movable plate. Then, the blocking block on the support rod blocks the second blocking block on the sliding plate, causing the compression plate on the movable plate to compress the buffer spring. The spring force provides initial cushioning protection when the monitor tipps over, allowing it to automatically reset as much as possible.
[0023] The wedge-shaped arrangement of the pressing plate on the movable plate and the end of the support rod allows the support rod to rotate slightly by the pressing plate, causing the first blocking block to disengage from the second blocking block. The instantaneous elastic force of the buffer spring then quickly pushes the movable block, which in turn pushes the connecting rod, which in turn pushes the support rod to rotate and open, thus supporting and protecting the monitor and preventing it from being damaged by collision with the desktop.
[0024] In summary, this device not only provides initial cushioning protection for monitors used in radiotherapy after a collision and tipping, but also provides stable support and protection if the monitor cannot be reset, preventing it from falling directly onto the table and causing damage.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0035] Please see Figures 1-4 and Figure 6The present invention provides a technical solution: a device for real-time monitoring of radiotherapy process, including a monitoring display 1 for real-time monitoring of the internal condition of the treatment room and a support leg 2 for supporting the monitoring display 1. Two symmetrically distributed movable slots 5 are opened on the back of the monitoring display 1, and a movable plate 7 is slidably installed inside the movable slot 5. A movable rod 4 that slides through the bottom side wall of the monitoring display 1 is fixedly connected to the bottom end of the movable plate 7, and a collision rod 3 that is perpendicular to the movable rod 4 is fixedly connected to the bottom end of the movable rod 4.
[0036] Reference Figures 2-4 and Figure 6 The movable plate 7 is provided with a sliding plate 18 that slides vertically. The movable plate 7 has a groove 8 on the side near the back of the monitor 1 for the sliding plate 18 to slide stably. The top view of the sliding plate 18 and the groove 8 are both T-shaped, which can ensure the stability of the movable plate 7 when it moves upward along the movable groove 5. The bottom end of the side of the movable plate 7 near the back of the monitor 1 is fixedly connected to a pressing plate 9. A buffer spring 11 is fixedly connected between the side of the sliding plate 18 and the pressing plate 9 that are close to each other. The bottom end of the sliding plate 18 near the back of the monitor 1 is fixedly connected to a second blocking block 25. A support rod 6 is rotatably installed on the back of the monitor 1. A first blocking block 24 is fixedly installed at the bottom end of the support rod 6 near the side of the sliding plate 18 to block the second blocking block 25.
[0037] Reference Figure 2 , Figure 3 , Figure 6 and Figure 7 The support rod 6 has slots 13 on both sides, and two sets of insert plates 14 that match the slots 13 are slidably installed on the back of the monitoring display 1. Limiting blocks 16 are fixedly installed on the insert plates 14, and limiting grooves 17 for the limiting blocks 16 to slide are opened on the back of the monitoring display 1. The sliding of the limiting blocks 16 inside the limiting grooves 17 can ensure the stability of the insert plates 14 when they move laterally.
[0038] Reference Figure 2 , Figure 3 , Figure 6 and Figure 7 The insert plate 14 has a rectangular slot 15 that runs through its body, and the movable plate 7 has a drive assembly that cooperates with the rectangular slot 15 on the side near the back of the monitor 1. The drive assembly includes a fixed rod 23 that is fixedly installed on the side of the movable plate 7 near the back of the monitor 1, and a drive plate 12 that is perpendicular to the fixed rod 23 is fixedly connected to the end of the fixed rod 23. The top of the drive plate 12 is wedge-shaped. When the insert plate 14 is inserted into the slot 13, it can effectively prevent the support rod 6 from rotating when the monitor 1 is tilted, so that the support rod 6 drives the first blocking block 24 to rotate and the first blocking block 24 is disengaged from the blocking state of the second blocking block 25.
[0039] The specific implementation of this device for real-time monitoring of the radiotherapy process, which provides initial buffer protection for the monitoring display 1 used to monitor the internal conditions of the treatment room during radiotherapy, is as follows:
[0040] When the monitor 1 is knocked over by a collision, the insert plate 14 is first inserted into the slot 13 of the support rod 6 to limit and fix the support rod 6. When the collision rod 3 comes into contact with the table and is squeezed, the collision rod 3 pushes the movable rod 4, which pushes the movable plate 7 to slide inside the movable groove 5. At this time, due to the obstruction of the first blocking block 24 against the second blocking block 25, the slide plate 18 will not be displaced in the vertical direction. Therefore, when the movable plate 7 slides inside the movable groove 5, it will drive the pressing plate 9 to move and cooperate with the slide plate 18 to compress the buffer spring 11. The elastic force of the buffer spring 11 protects the monitor 1 as a whole, so that the monitor 1 can automatically reset as much as possible through the elastic force of the buffer spring 11, thereby providing initial buffer protection for the monitor 1.
[0041] Example 2
[0042] If the spring force of the buffer spring 11 is insufficient to automatically reset the monitoring display 1, this embodiment adds a support and protection operation to the monitoring display 1 that continues to tilt, based on embodiment one. (Refer to...) Figures 2-4 and Figure 6 The specific structure includes: a limiting rod 10 is fixedly connected to the bottom end of the slide plate 18, and the limiting rod 10 is slidably connected to the extrusion plate 9; a buffer spring 11 is sleeved on the outside of the rod body of the limiting rod 10; and an anti-detachment block 26 is fixedly connected to the bottom end of the limiting rod 10 to prevent the limiting rod 10 from detaching from the extrusion plate 9. The limiting rod 10 can ensure the stability of the slide plate 18 when it moves on the movable plate 7, and the anti-detachment block 26 can prevent the slide plate 18 from detaching from the extrusion plate 9 during subsequent movements.
[0043] Reference Figure 4 and Figure 5 The bottom ends of the extrusion plate 9 and the support rod 6 are both wedge-shaped, and the extrusion plate 9 and the bottom ends of the support rod 6 slide in contact. The movable block 20 located above the slide plate 18 is slidably installed inside the movable groove 5, and a connecting rod 19 is hinged between the top of the movable block 20 and the support rod 6.
[0044] Reference Figure 4 and Figure 5 The movable block 20 is fixedly connected to the side of the monitoring display 1 near the front of the monitoring display 1. The monitoring display 1 is provided with a limiting groove 21 for the limiting block 22 to slide on the inner side of the movable groove 5. The sliding of the limiting block 22 inside the limiting groove 21 can ensure the stability of the movable block 20 when it moves in the vertical direction.
[0045] The specific implementation method for supporting and protecting the monitoring display 1 in this embodiment is as follows:
[0046] When the movable plate 7 slides along the inside of the movable groove 5, the movable plate 7 drives the fixed rod 23 to move, and the fixed rod 23 then drives the drive plate 12. The drive plate 12, with its wedge-shaped top, and its inclined surface engaging with the rectangular groove 15, allows the insert plate 14 to move away from the slot 13, and drives the limiting block 16 to slide inside the limiting groove 17. When the insert plate 14 is completely disengaged from the slot 13, and when the pressing plate 9 on the movable plate 7 contacts the end of the support rod 6, due to the pressure plate 9 and the bottom of the support rod 6... Both ends are wedge-shaped, so the pressing plate 9 will push the support rod 6, causing the support rod 6 to rotate slightly, thereby allowing the blocking block 1 24 to disengage from the blocking block 25. At this time, the elastic force of the buffer spring 11 is released instantly, pushing the slide plate 18 to move quickly. The slide plate 18 then pushes the movable block 20, causing the movable block 20 to push the connecting rod 19. The connecting rod 19 then pushes the support rod 6, causing the support rod 6 to unfold. This provides support for the entire monitoring display 1, preventing it from falling directly onto the table and causing damage to the monitoring display 1.
[0047] Working principle: This device for real-time monitoring of radiotherapy processes, when the monitoring display 1 is impacted and tipped over, firstly, the insert plate 14 is inserted into the slot 13 of the support rod 6 to limit and fix the support rod 6. When the impact rod 3 contacts the table and is squeezed, the impact rod 3 pushes the movable rod 4, causing the movable rod 4 to push the movable plate 7 to slide inside the movable groove 5. At this time, due to the obstruction of the first blocking block 24 against the second blocking block 25, the slide plate 18 will not be displaced in the vertical direction. Therefore, when the movable plate 7 slides inside the movable groove 5, it will drive the compression plate 9 to move and cooperate with the slide plate 18 to compress the buffer spring 11. The elastic force of the buffer spring 11 protects the entire monitoring display 1, allowing the monitoring display 1 to automatically reset as much as possible through the elastic force of the buffer spring 11, thereby providing initial buffer protection for the monitoring display 1.
[0048] To further enhance the multi-directional protection function of the monitoring display 1, the aforementioned protective structures can also be installed on both sides of the monitoring display 1 during actual use, ensuring that the monitoring display 1 can also receive effective collision protection when tilted to the sides, thus preventing damage to the monitoring display 1.
[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
