Description

Technical Field

[0002] Radiation therapy has become one of the mainstays of cancer treatment. Statistics show that over 70% of cancer patients require treatment with radiotherapy alone or in combination with other therapies. Currently, the primary method of tumor radiotherapy is flash therapy, which reduces damage to normal tissue while maintaining tumor toxicity. Currently, clinical trials using electron, X-ray, and proton flash therapy have been successfully conducted. The ultra-high dose rates of flash therapy present unique challenges for dose measurement, beam control and verification, and treatment planning systems. In flash therapy, dose measurement typically requires exceptional ultra-high dose rate independence, excellent spatiotemporal resolution, and tissue equivalence.

[0003] Flash-RT (flash therapy) has been a cutting-edge technology and a research hotspot in recent years in international cancer radiotherapy research. It uses an extremely high dose rate (typically greater than 100 Gy / s) to deliver the entire radiation dose to the target area within a very short time (1 to 50 milliseconds). Studies have shown that it causes less damage to normal tissue and can significantly reduce radiation treatment time.

[0004] Currently, cancer radiotherapy equipment has begun to use new laser plasma acceleration technology to perform external irradiation radiotherapy by generating energy electron beams. Usually, the electron beams are accelerated by lasers and then introduced into the tumor site through a thin catheter. In existing technologies, the angle adjustment capability of electron flash therapy devices is limited, making it difficult to meet the requirements of precise irradiation of different parts and angles.

[0005] In view of the above technical problems, improvements need to be made. Utility Model Content

DETAILED DESCRIPTION

[0029] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings.

[0030] Example 1:

[0031] like Figures 1-4 As shown, Figure 1 This is a front view of the first embodiment of the present utility model; Figure 2 This is the first embodiment of the present invention Figure 1 AA cross-sectional view; Figure 3 This is a schematic structural diagram of the first embodiment of the present invention; Figure 4 This is a schematic structural diagram of a rotating assembly according to a first embodiment of the present invention;

[0032] Specifically, the variable-angle electronic flash therapy device includes an electronic flash therapy device base 1; an electronic flash therapy housing 2, which is rotatably mounted on the electronic flash therapy device base 1; a high-energy electron accelerator 100, which is built into the electronic flash therapy housing 2 and is used to provide a pulsed electron beam; an electronic flash therapy head 200, which is mounted on the end of the electronic flash therapy housing 1, and the distal end of the electronic flash therapy head 200 is used to irradiate an irradiation site 3; the irradiation site 3 is located on the electronic flash therapy device base 1 and is arranged corresponding to the electronic flash therapy head 200. The above scheme enables the electronic flash therapy housing 2 to irradiate at multiple angles: the electron beam generated by the high-energy electron accelerator 100 located in the electronic flash therapy housing 2 can swing at an angle of plus or minus 45 degrees, which can adapt to different lesion sites and treatment needs, thereby improving the accuracy of treatment.

[0033] The base 1 of the electronic flash therapy device includes a positioning seat 10 and a support frame 11; the electronic flash therapy shell 2 is rotatably assembled on one end of the support frame 11, and the irradiation part 3 is located at the other end of the support frame 11; specifically, the provision of the positioning seat 10 and the support frame 11 improves the stability and safety of the entire device, and at the same time, also improves operational flexibility: the angle of the electronic flash therapy shell 2 can be adjusted in real time according to actual conditions to provide patients with personalized treatment plans.

[0034] A rotating base 20 is fixed to the electronic flash therapy housing 2 near the support frame 11. A rotating assembly 4 is mounted between the support frame 11 and the rotating base 20. Specifically, the rotating assembly 4 includes a rotating shaft 42 with support bearings 40 mounted at both ends. A variable-angle microwave tube 41 is mounted within the rotating shaft 42, with the support bearings 40 and microwave tube 41 arranged concentrically. This structural design ensures the stability and precision of the rotating assembly 4 during operation.

[0035] An installation channel is formed in the rotating shaft 42, and a microwave tube 41 is installed in the channel. Specifically, the microwave tube 41 is a flexible conduit, which has the characteristics of small diameter and light transmission, and has a wider range of application functions.

[0036] The support frame 11 has an arc-shaped structure, and an inwardly concave arc-shaped guide opening 12 is formed on the top of the support frame 11. The rotating seat 20 moves up and down along the inwardly concave arc-shaped guide opening 12; the rotating seat 20 drives the electronic flash therapy shell 2 to move, which can adapt to different lesion sites and treatment needs and improve the accuracy of treatment.

[0037] The electron flash therapy shell 2 is designed as a hollow tubular structure, and the high-energy electron accelerator 100 is built into the hollow tube; for the electron flash therapy shell 2, preferably, it can be designed into a pipe shape, accordingly, the electrons with a divergent angle in the high-energy electron accelerator 100 can be quickly transmitted to the end to treat the irradiation part 3.

[0038] In addition, the high-energy electron accelerator 100 directly irradiates the irradiated part 3 to produce a therapeutic effect. The electron beam has high brightness and can meet the requirements of flash therapy. The treatment process is safer and more effective, and the number of treatments can be reduced, shortening the treatment cycle.

[0039] The electronic flash therapy head 200 can be detachably assembled on the electronic flash therapy housing 2. Through the above design, after one radiotherapy is completed, the electronic flash therapy head 200 can be replaced to carry out the next radiotherapy until all treatments are completed. The electronic flash therapy head 200 is located at the end of the electronic flash therapy housing 2, and the high-energy electron accelerator 100 interacts with the electronic flash therapy head 200 to generate plasma and electron beam.

[0040] The working gas used can be hydrogen or other types of gas. Different gas atoms produce different numbers of electrons. Before actual use, the appropriate density or pressure range can be set according to the gas type to obtain better results. For example, for hydrogen gas, it can be set to standard atmospheric pressure at room temperature.

[0041] The technical solution of the above embodiment, by designing the electronic flash therapy head 200, controls the high-energy electron beam input to the tumor site to match the shape of the tumor site, facilitates the conformal shaping of the high-energy electron beam to match the shape of the tumor, and can perform targeted and precise radiotherapy on tumor sites of various shapes, giving full play to the advantages of precise radiotherapy, avoiding radiation damage to normal tissues passed by the rays, making the treatment process safer and more effective, and facilitating the patient's postoperative recovery, with better treatment effects.

[0042] Example 2:

[0043] like Figure 5-Figure 6 As shown, Figure 5 This is a front view of the second embodiment of the present utility model; Figure 6 This is a schematic structural diagram of the second embodiment of the present utility model;

[0044] A variable-angle electronic flash therapy device includes an electronic flash therapy device base 1; an electronic flash therapy housing 2 rotatably mounted on the electronic flash therapy device base 1; a high-energy electron accelerator 100 built into the electronic flash therapy housing 2 and configured to provide a pulsed electron beam; an electronic flash therapy head 200 mounted at an end of the electronic flash therapy housing 1, the distal end of the electronic flash therapy head 200 configured to irradiate an irradiation site 3; the irradiation site 3 is located on the electronic flash therapy device base 1 and arranged corresponding to the electronic flash therapy head 200; and a guide rail 300 located between the electronic flash therapy device base 1 and the electronic flash therapy housing 2 and configured to adjust the positional relationship between the electronic flash therapy housing 2 and the irradiation site 3.

[0045] The above solution enables the electron flash therapy shell 2 to irradiate at multiple angles: the electron beam generated by the high-energy electron accelerator 100 located in the electron flash therapy shell 2 can swing at an angle of plus or minus 45 degrees. This design enables the electron beam to adjust its angle within a larger range to adapt to different treatment sites and needs.

[0046] For example, when irradiating different areas of the head, an angle swing range of plus or minus 45 degrees can more accurately irradiate the lesion site while reducing damage to surrounding normal tissues.

[0047] The above-mentioned structural design enables the device to work with the electronic flash therapy housing 2 to deliver electron beam irradiation at multiple angles and heights. This greatly enhances the effectiveness of electronic flash therapy, providing patients with more precise and effective treatment. For irregularly shaped tumors, adjusting the angle and height of the electronic flash therapy housing 2 allows for all-around irradiation, improving cure rates.

[0048] The base 1 of the electronic flash therapy device includes a positioning seat 10 and a support frame 11; the electronic flash therapy shell 2 is rotatably assembled on one end of the support frame 11, and the irradiation part 3 is located at the other end of the support frame 11; specifically, the provision of the positioning seat 10 and the support frame 11 improves the stability and safety of the entire device, and at the same time, also improves operational flexibility: the angle of the electronic flash therapy shell 2 can be adjusted in real time according to actual conditions to provide patients with personalized treatment plans.

[0049] The support frame 11 is an arc-shaped structure with a guide groove 13 formed therein. The guide rail 300 is also an arc-shaped structure, embedded in the guide groove 13 and moving along the guide groove 13. In this embodiment, the guide rail 300 enables an arc-shaped sliding movement between the bracket with the curved guide rail 300 and the support frame 11, thereby enabling the electron flash therapy housing 2 to be slid to different heights. In this way, the electron beam within the high-energy electron accelerator 100 can be irradiated at different heights, further enhancing the flexibility and adaptability of treatment.

[0050] For example, when treating tumors in different parts of the body, the height of the electronic flash therapy shell 2 is adjusted according to the location and depth of the tumor to ensure that the electron beam can accurately irradiate the target area.

[0051] The assembly method of the embodiment is as follows:

[0052] 1. Install the electronic flash therapy device base 1 in a suitable position and ensure its stability; then install the bracket with the arc guide rail 300 on the support frame 11 of the device, and check the smoothness of the arc sliding.

[0053] 2. Then install the rotating shaft 42, and concentrically install the variable-angle microwave tube 41 and the support bearing 40 at the rotating shaft 42, and connect the electronic flash therapy shell 2, the high-energy electron accelerator 100 and the electronic flash therapy head 200.

[0054] 3. Finally, debug to ensure that the electron beam of the high-energy electron accelerator 100 can accurately swing within a range of plus or minus 45 degrees, and that the electronic flash therapy shell 2 can smoothly slide to different horizontal heights on the bracket with the arc guide rail 300.

[0055] The operation method of the embodiment is as follows:

[0056] 1. When performing electronic flash therapy, first adjust the angle of the electronic flash therapy shell 2 according to the specific condition of the patient and the treatment needs, and control the high-energy electron accelerator 100 to make the electron beam irradiate the lesion site at a suitable angle.

[0057] 2. Then, according to the height of the lesion site, slide the electronic flash therapy shell 2 to the corresponding horizontal height through the bracket with the arc guide rail 300.

[0058] 3. During the treatment process, the angle and height can be adjusted in real time according to the actual situation to achieve the best treatment effect.
