Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an integrated device for brachytherapy and CT equipment. Background Technology

[0002] In the current medical environment, the CT room is typically used for medical imaging, while the brachytherapy room is used for treatment, and the two are often separate. Traditional high-precision CT scanners are usually fixed in the CT room and cannot be moved. In contrast, brachytherapy equipment typically uses high-dose-rate radiation sources, and during treatment, the radiation source leaves the reservoir and generates high-energy rays, therefore, the protection requirements for its treatment room are extremely high.

[0003] When a patient undergoes brachytherapy, after the applicator or needle is inserted, the patient is transferred from the operating room to the CT scan table in the CT room via a transport bed. After the scan, the patient is transferred from the CT table to the transport bed and then to the treatment room entrance to await treatment. Based on the CT data, the physician delineates the target area, identifies organs at risk (such as the bladder, small intestine, and rectum), and designs a radiotherapy plan. The entire process typically takes about 40 minutes. Several issues arise during this process: 1. Patients need to be transferred between the CT room and the treatment room multiple times, which not only increases their physical discomfort but may also affect their mental and physical health; 2. The radiotherapy plan is based on the position of the applicator or implanted needle in the CT scan image. During patient transfer, the position of the applicator may shift, resulting in reduced treatment accuracy. 3. During the treatment waiting period, physiological factors such as intestinal peristalsis and rectal insufflation may cause changes in the target area, organs at risk, and applicator position, thereby affecting the radiotherapy effect and accuracy; 4. If image-guided therapy is to be performed, the position of the applicator or implanted needle must be confirmed before each treatment to ensure it has not shifted. The patient must be returned to the CT room for another scan. This is both time-consuming and labor-intensive, and the transport itself carries the risk of the applicator or implanted needle shifting.

[0004] To address the above issues, this invention proposes an innovative design that integrates brachytherapy equipment and CT equipment within the same room, constructing an integrated room according to brachytherapy protection standards. Through a combination of an automated protection system and a track-based movement system, the brachytherapy equipment is normally stored in a protective compartment. Only during treatment does the protective barrier automatically open, and the equipment is automatically moved to the CT bedside via the track system. This design ensures the safety of operators and other patients during CT scans, avoiding unnecessary radiation exposure. It also eliminates the risk of applicator displacement due to patient transport, facilitating image-guided brachytherapy and improving treatment accuracy. Summary of the Invention

[0005] This invention provides an integrated design for a brachytherapy device and a CT scanner that meet brachytherapy protection standards. The aim is to achieve an efficient and safe treatment process through the combination of a track system and an automated protection system. The integrated treatment room is designed according to brachytherapy protection standards, ensuring that both devices meet radiation protection requirements during use. In this standardized protective environment, the brachytherapy device and the CT scanner can work seamlessly together within the same room, avoiding frequent patient transfers before and after treatment, improving treatment efficiency, and reducing patient positioning errors.

[0006] In the design, when treatment is required, the automated protection system automatically opens the protective barrier, and the brachytherapy equipment automatically moves from the protective compartment to the CT bed via a track system. After connecting the applicator or insertion needle, the operator leaves the machine room to remotely operate the treatment equipment and perform the treatment. After treatment, the operator removes the tubing, and the treatment equipment automatically moves back to the protective compartment via the track system. The automated protection system automatically closes the protective barrier, ensuring the safety of the treatment equipment during normal storage, without affecting normal CT scanning operations, and minimizing radiation exposure. To address the problems existing in the background technology, the present invention provides an integrated design of a brachytherapy device and a CT device that combines automated protection and a track system. The specific technical solution is as follows: An integrated brachytherapy and CT device includes a ground structure, a moving component, and a brachytherapy component. The CT device is mounted on the upper right side of the ground structure. A frame is fixedly connected to the upper rear part of the ground structure. A partition is fixedly connected to the upper middle part of the ground structure. An electric push rod is fixedly connected to the upper rear part of the partition. A fixing plate is fixedly connected to the left front part of the partition.

[0007] Limiting rods are fixedly connected to the upper and lower rear ends of the fixed plate. A baffle is sleeved on the outer surface of the two limiting rods. A push block is fixedly connected to the middle of the upper end of the baffle, and the push block is fixedly connected to the output end of the electric push rod. A track groove is opened at the upper end of the ground structure. A track is fixedly connected to the inner wall of the track groove. The brachytherapy component is mounted on the moving component. The moving component is slidably connected to the track groove and is used to drive the brachytherapy component to move along the track.

[0008] Preferably, the moving component includes a support portion, the lower end of which is fixedly connected to a connecting frame, and two driving devices are provided on both the lower left and lower right sides of the support portion.

[0009] Preferably, the brachytherapy component is installed at the upper middle part of the support, and the connecting frame is interlocked with the track groove.

[0010] Preferably, the connecting frame is sleeved with the track.

[0011] Preferably, the baffle is interlocked with the card frame.

[0012] Preferably, the end of the track away from the CT equipment is also provided with an isolation and protective cabinet for storing brachytherapy components.

[0013] By adopting the above technical solution, the entire mobile component is moved to a different position by a driving device, and the connecting frame is connected to the track on the ground structure. This limits the movement of the mobile component and ensures the precise positioning of the treatment device during the movement.

[0014] Preferably, the connecting frame is sleeved with the track system, and the opening and closing of the protective baffle is automatically adjusted by an electric push rod. Preferably, the baffle is interlocked with the retaining frame to ensure the effectiveness and stability of the protective system. Preferably, the end of the track away from the CT equipment is also equipped with an isolation protective cabinet for storing brachytherapy components. This protective cabinet is designed according to the protection standards for brachytherapy to ensure safe storage of the treatment equipment when not in use and to prevent unnecessary radiation leakage.

[0015] Preferably, the isolation and protection cabinet includes a protective cavity 15 and a sealing door that can close or open the protective cavity.

[0016] Preferably, the end of the track away from the CT equipment extends to a corner of the CT room away from the CT equipment, and the bottom surface of the protective cavity is provided with a guide rail that matches the track groove structure, with the guide rail flush with the top surface of the track.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a moving component with a connecting frame, and connecting the connecting frame to the track, the position of the brachytherapy component can be adjusted through the drive of two drive devices, so that patients can complete the treatment process without getting out of bed after CT.

[0024] In this invention, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0025] Please see Figure 1-5This invention provides an integrated device for brachytherapy and CT equipment 3, including a ground structure 1, a moving component 2, and a brachytherapy component 22. The CT equipment 3 is mounted on the upper right side of the ground structure 1. A frame 4 is fixedly connected to the upper rear part of the ground structure 1. A partition 5 is fixedly connected to the upper middle part of the ground structure 1. An electric push rod 6 is fixedly connected to the upper rear part of the partition 5. A fixing plate 9 is fixedly connected to the left front part of the partition 5.

[0026] In this embodiment, the upper and lower rear ends of the fixed plate 9 are both fixedly connected to limit rods 7. The outer surfaces of the two limit rods 7 are jointly fitted with baffles 10. The upper middle part of the baffles 10 is fixedly connected to a push block 8, and the push block 8 is fixedly connected to the output end of the electric push rod 6. The upper end of the ground structure 1 is provided with a track groove 11. The inner wall of the track groove 11 is fixedly connected to a track 12. The brachytherapy component 22 is mounted on the moving component 2. The moving component 2 is slidably connected to the track groove 11 and is used to drive the brachytherapy component 22 to move along the track 12.

[0027] Specifically, the baffle 10 and the frame 4 are interlocked to ensure the effectiveness and stability of the protection system. Both the baffle 10 and the partition 5 can be made of lead plate, and their thickness is set according to actual conditions, generally between 5mm and 10mm.

[0028] In this invention, the automatic movement of the brachytherapy component is achieved by controlling the movement of the mobile component along the track. A partition is located in the center of the ground structure, on which an electric push rod and a protective baffle are mounted. The protective baffle can be automatically opened and closed under the control system, allowing for automatic switching of the protected area between treatment and non-treatment states.

[0029] The above scheme uses two limiting rods 7 to limit and support the movement of the baffle 10, and the electric push rod 6 to push the push block 8, which can push the baffle 10 to its working position, thereby completing the separation and connection of the left and right sides of the ground structure 1.

[0030] In this embodiment, the end of the track 12 furthest from the CT equipment 3 is also equipped with an isolation and protective cabinet 13 for housing the brachytherapy component 22. The isolation and protective cabinet 13 includes a protective cavity 15 for housing the brachytherapy component 22 and a sealed door 14 (including but not limited to a manually operated swing door or an electrically operated sliding door) that can close or open the protective cavity 15. The sealing door 14 and the side walls of the protective cavity 15 can both be made of lead plate with a thickness between 5mm and 10mm. By placing the brachytherapy component 22 inside the isolation and protective cabinet 13, the lead protection properties of the isolation and protective cabinet 13 can be used to prevent the radiation that may be generated by the brachytherapy equipment body 221 from spreading outward, thus ensuring the personal safety of medical personnel.

[0031] The protective cabinet is designed according to the protection standards for brachytherapy, ensuring safe storage of treatment equipment when not in use and preventing unnecessary radiation leakage.

[0032] Preferably, the end of the track 12 away from the CT equipment 3 extends to the corner of the CT room away from the CT equipment 3. The bottom surface of the protective cavity 15 of the isolation cabinet 13 is provided with a guide rail that matches the structure of the track groove 11. The guide rail is flush with or slightly lower than the top surface of the track 12, so as to facilitate the brachytherapy equipment assembly to be pushed into the isolation cabinet 13 along the track 12, or to push out the brachytherapy equipment assembly in the isolation cabinet 13 and move it along the track 12 to the side of the CT equipment 3. The other end of the track 12 extends to one side of the CT equipment 3, so that after the brachytherapy equipment assembly moves to the other end of the track 12, intubation radiotherapy can be performed on the patient on the CT bed.

[0033] Specifically, a recess of a certain height can be made in a corner of the CT room away from the CT equipment 3 to house the isolation and protective cabinet 13. The height of the recess should be such that the guide rail is flush with or slightly lower than the top surface of the track 12. To facilitate the closing or opening of the sealing door 14 of the protective cavity 15, the distance between the guide rail and the end of the track 12 away from the CT equipment 3 should be slightly greater than the thickness of the sealing door 14.

[0034] In this embodiment, as Figure 6 As shown, the moving component 2 includes a support part 21, and a connecting frame 24 is fixedly connected to the lower end of the support part 21. The connecting frame 24 is sleeved with the track 12 and inserted into the track groove 11. Two drive devices 23 are provided on both the lower left and lower right sides of the support part 21.

[0035] A brachytherapy assembly 22 is fixedly mounted on the upper end of the support 21. The brachytherapy assembly 22 generally includes a base, a brachytherapy device body 221, and a pull ring 222, and its telescopic lifting function is achieved through a telescopic cylinder. The moving assembly 2 can be installed at the bottom of the base, and when the connecting frame 24 is engaged with the track 12, the rollers on both sides of the base of the brachytherapy assembly 22 contact the ground. The drive device 23 can be configured as a structure combining a drive motor and rotating wheels connected to the drive motor. The drive motor drives the rotating wheels to rotate, driving the moving assembly 2 and the brachytherapy assembly 22 to move along the track 12.

[0036] On both sides of the base, telescopic lifting mechanisms, such as telescopic rods, can be installed to drive the rollers to rise and fall. When the brachytherapy component 22 is removed from the track 12, the rollers are driven by the telescopic lifting mechanism to lower the rollers and bring them into contact with the ground. At the same time, the connecting block in the moving component 2 is disengaged from the ground, facilitating the movement of the brachytherapy component 22.

[0037] Thus, the rollers under the brachytherapy device body 221 can ensure that the brachytherapy device body 221 moves stably along the track 12 and avoids shaking. They can also facilitate pushing the brachytherapy component 22 and moving it into the protective cavity 15 of the isolation cabinet 13.

[0038] Since the brachytherapy component 22 is an afterloading device, its structure is a conventional technique in this field, and therefore will not be described in detail here.

[0039] By using the above solution, the connecting frame 24 on the moving component 2 is connected to the track 12, the support part 21 is driven by two driving devices 23, and the moving component 2 is limited by the connecting frame 24, so as to avoid the moving component 2 from deviating during the movement and improve stability.

[0040] Preferably, the end of the track 12 away from the CT equipment 3 is also provided with an isolation and protective cabinet 13 for storing the brachytherapy component 22.

[0041] By adopting the above technical solution: the entire mobile component 2 and the brachytherapy component 22 are moved to their positions by the drive device 23, and the connecting frame 24 is connected to the track 12 on the ground structure 1, which can limit the movement of the mobile component 2 and ensure the precise positioning of the treatment equipment during the movement.

[0042] Preferably, the connecting frame 24 is sleeved with the track 12 system, and the opening and closing of the protective baffle 10 is automatically adjusted by the electric push rod 6.

[0043] It should be noted that the present invention is an integrated device for brachytherapy and CT equipment 3. During use, when the device is not in use, that is, when the moving component 2 does not need to work, it is located on the left side of the ground structure 1. At this time, the baffle 10 and the frame 4 are interlocked. This connection method allows the baffle 10 to effectively close and isolate the channel between the frame 4 and the partition 5. The partition 5 itself serves to separate the treatment area, and the closure of the baffle 10 further ensures the independence between different areas, preventing unauthorized personnel or objects from entering the specific treatment area, and also prepares for the subsequent movement and use of the moving component 2.

[0044] When treatment is needed for a patient who has completed a CT scan and the moving component 2 is required, the electric push rod 6 is activated. The electric push rod 6 begins to work, applying a pulling force to the push block 8. Driven by the push block 8, the connection between the baffle 10 and the frame 4 gradually separates. This process releases the baffle 10 from the closed isolation of the channel, opening a passage for the moving component 2 to move smoothly along the track 12. The connecting frame 24 on the moving component 2 is fitted onto the track 12. After the baffle 10 separates from the frame 4, the two drive devices 23 are activated simultaneously, driving the support 21. Under the action of the driving force, the moving component 2 moves along the track 12 from the left side of the ground structure 1 to the right side area. The track 12 provides a stable path and guidance for the movement of the moving component 2, ensuring the accuracy and smoothness of the movement process, enabling the moving component 2 to quickly and accurately reach the area where the patient needs treatment.

[0045] In summary, this invention integrates CT equipment and brachytherapy equipment within the same room and is designed according to the protection standards for brachytherapy. Through the coordinated control of an automated protection system and a track system, automatic positioning, precise movement, and safety protection of the treatment equipment are achieved. This design allows brachytherapy to be performed directly within the CT room, avoiding applicator displacement caused by patient transfer between the CT and treatment rooms. It also facilitates pre-treatment image guidance, improving treatment safety and efficiency, optimizing the treatment process, and saving construction costs. Simultaneously, it effectively reduces radiation exposure risks and ensures the safety of operators and other patients during non-treatment periods. The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
