Description

Technical Field

[0001] This utility model relates to the field of proton therapy equipment technology, specifically a protective cover for the rotating frame of a proton therapy device. Background Technology

[0002] Proton therapy, as an advanced tumor radiotherapy technology, leverages the physical properties of the Bragg peak to precisely deliver high-dose radiation to the tumor target area while minimizing damage to surrounding healthy tissues. In a proton therapy system, the rotating gantry is the core component enabling multi-angle irradiation. Its rotational motion allows the treatment head to be positioned around the patient, thus meeting the treatment needs at different angles.

[0003] However, the rotating frame presents the following technical challenges during operation:

[0004] 1. Radiation protection issues: Secondary radiation (such as neutrons and gamma rays) is generated during proton therapy, requiring strict radiation shielding of the rotating frame area. Traditional concrete protective structures are difficult to meet the dynamic sealing requirements of rotating components.

[0005] 2. Compatibility between mechanical movement and protection: The continuity and sealing of the protective shield must be ensured during frame rotation to prevent radiation leakage, while also adapting to changes in the position of the treatment head. Existing protective shields mostly use fixed lead plates or segmented shielding structures, which have problems such as insufficient shielding at seams and easy wear or jamming of flexible components.

[0006] 3. Structural stability and aesthetics: The protective cover needs to support heavy medical equipment and withstand long-term mechanical vibration, while traditional split designs are prone to loosening of the connection parts; in addition, exposed structures such as bolts may affect the overall aesthetics and cleanliness of the equipment. Utility Model Content

[0007] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a rotating frame protective cover for proton therapy equipment, which has significant advantages in terms of radiation protection, dynamic sealing, structural stability, ease of maintenance and aesthetics. It can effectively improve the safety, reliability and service life of proton therapy equipment, and has high clinical application value and market promotion potential.

[0008] The technical solution adopted by this utility model to achieve the above-mentioned objective is: a rotating frame protective cover for a proton therapy device, including a base and a wall panel and a mounting base fixed to the base. The wall panel has an arc-shaped opening, and the mounting base has an assembly plate that is coaxially arranged with the arc-shaped opening.

[0009] It also includes an outer protective plate, an inner protective plate, and a flexible protective plate. The outer and inner protective plates each consist of multiple sets of sealed splices. The outer edge of the outer protective plate is sealed and fixed to the arc-shaped opening, and the inner edge of the inner protective plate is sealed and fixed to the outer edge of the assembly plate. The bottom outer and inner protective plates are sealed and fitted to the base. The inner edge of each set of outer protective plates is fixed with an outer guide groove, and the outer edge of each set of inner protective plates is fixed with an inner guide groove. The base has a receiving groove, and the two sides of the receiving groove have an outer connecting groove and an inner connecting groove, respectively. The outer connecting groove and the inner connecting groove are matched and connected to the outer guide groove and the inner guide groove, respectively. The two sides of the flexible protective plate are slidably inserted into the outer guide groove and the inner guide groove, respectively. The bottom of the flexible protective plate is arranged in the receiving groove and is slidably inserted into the outer connecting groove and the inner connecting groove.

[0010] Based on the above technical solutions, in order to ensure the aesthetic effect of the connection between the outer guard plate and the arc-shaped opening and the connection between the inner guard plate and the assembly plate, the following technical solutions are provided.

[0011] A positioning arc plate is fixedly connected to the inner end of the arc-shaped opening, and a positioning arc groove is opened at the outer end of the arc-shaped opening. The outer edge of the outer guard plate is fixedly installed on the positioning arc plate, and an outer decorative plate is fixedly assembled in the positioning arc groove. The inner edge of the outer decorative plate is closely fitted with the outer edge of the outer guard plate.

[0012] The assembly plate has an outer step groove and an inner step groove. The inner edge of the inner guard plate is fixedly installed in the outer step groove. An inner decorative panel that fits snugly against the inner guard plate is fixedly installed in the inner step groove. The inner decorative panel includes multiple sets arranged in a ring array. A decorative plate arranged on the outside of the inner decorative panel is also fixedly installed in the inner step groove.

[0013] Based on the above technical solutions, in order to ensure that the active part of the proton therapy device can operate stably and to treat patients inside the opening of the device, the following technical solutions are provided.

[0014] It also includes two sets of arc-shaped guide rails fixedly installed on the base and arranged coaxially with the outer and inner protective plates. The two sets of arc-shaped guide rails are respectively arranged around the outer and inner protective plates. A rotating bracket is assembled between the two sets of arc-shaped guide rails, and the treatment head of the proton therapy device is fixedly installed on the rotating bracket.

[0015] Based on the above technical solutions, in order to ensure that the treatment connector can be arranged inside the outer protective plate, the inner protective plate and the flexible protective plate and to achieve effective treatment of the patient, the following technical solutions are provided.

[0016] The two ends of the flexible protective plate are fixedly connected to the treatment head, and the head of the treatment head is arranged on the inner side of the flexible protective plate.

[0017] Based on the above technical solutions, the outer guide groove provided on the outer protective plate is less restricted by the assembly characteristics and can fully wrap the upper and lower sides of the flexible protective plate. However, due to the limitation of the assembly space, the inner guide groove of the inner protective plate can only partially wrap one side of the flexible protective plate. In order to ensure the stability of the operation of the flexible protective plate, the following technical solutions are also required.

[0018] An arc-shaped pressure plate is also fixedly installed on the inner side of one of the arc-shaped guide rails. The arc-shaped pressure plate is arranged around the inner guide groove and fits against the outer wall of the flexible guard plate.

[0019] The beneficial effects of this utility model are:

[0020] 1. Excellent radiation protection performance: The base, wall panels, mounting base, and assembly plate are integrally cast with reinforced concrete, and lead plates or high-density shielding materials are built-in to ensure that the overall structure has extremely strong radiation protection capabilities, effectively blocking secondary radiation such as neutrons and gamma rays generated during proton therapy. The outer, inner, and flexible protective plates are all made of radiation-proof materials and feature a sealed splicing design to prevent radiation leakage and meet medical equipment safety standards.

[0021] 2. Dynamic sealing and stable operation: Through the sliding cooperation of the outer guide groove, inner guide groove, and flexible protective plate, the protective cover can dynamically adjust with the rotation of the treatment head, maintaining continuous shielding and avoiding the seam leakage problem of traditional segmented protective covers. The cooperation between the arc-shaped pressure plate and the inner guide groove further limits the displacement of the flexible protective plate, ensuring stable operation even at high speeds and reducing the risk of wear and jamming.

[0022] 3. Modular design facilitates installation and maintenance. The outer and inner protective panels adopt a fan-shaped splicing structure, which facilitates standardized production and on-site assembly, while reducing transportation and installation difficulties. The optimized design of the receiving groove, outer connection groove, and inner connection groove ensures that the flexible protective panel can still maintain stable sliding at the base, reducing the risk of deformation after long-term use.

[0023] 4. High structural strength and long-term durability: The base and wall panels are made of high-grade radiation-resistant concrete and reinforced with ribs to ensure the stability of the overall structure during heavy equipment operation and reduce the impact of vibration. The arc-shaped guide rail adopts a high-strength steel frame structure, combined with the load-bearing wheel design of the rotating bracket, enabling the treatment head to rotate smoothly and extending the service life of the equipment.

[0024] 5. Balancing aesthetics and functionality, the nested design of the exterior and interior decorative panels and decorative trays effectively conceals bolts and connectors, enhancing the overall appearance of the equipment while facilitating cleaning and maintenance. An LED light strip can be installed between the decorative tray and the interior decorative panel, not only enhancing the visual effect but also serving as an indicator of equipment status, thus improving the user experience.
