Technical Field

[0002] Radiotherapy has become one of the main ways to treat cancer. According to statistics, more than 70% of cancer patients need to be treated with radiotherapy alone or in combination with radiotherapy. At present, the main method of tumor radiotherapy is flash therapy, which can reduce damage to normal tissues while maintaining its lethality to tumors. At present, clinical trials based on electron, X-ray and proton flash therapy have been successfully carried out. The ultra-high dose rate of flash therapy brings unique challenges to dose measurement, beam control and verification, and treatment planning systems. In flash therapy, dose measurement usually requires excellent ultra-high dose rate independence, excellent spatiotemporal resolution, and tissue equivalence.

[0003] Flash-RT is a cutting-edge technology and research hotspot in recent years in international tumor radiotherapy research. It uses ultra-high dose rates (usually greater than 100Gy / s) to inject the entire radiotherapy dose into the target area in a very short time (1 to 50ms). Studies have found that it causes less damage to normal tissues and can significantly reduce the radiotherapy time.

[0004] Currently, cancer radiotherapy equipment has begun to use a new laser plasma acceleration technology to generate energy electron beams for external irradiation radiotherapy. Lasers are usually used to accelerate the electron beams, which are 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 precise irradiation requirements for different parts and angles.

[0005] In view of the above technical problems, improvements need to be made. Summary of the invention

DETAILED DESCRIPTION

[0029] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] Embodiment 1:

[0031] like Figure 1-Figure 4 As shown, Figure 1 is a front view of the first embodiment of the present invention; Figure 2 Embodiment 1 of the present invention Figure 1 AA section view; Figure 3 is a schematic structural diagram of Embodiment 1 of the present invention; Figure 4 is a structural schematic diagram of a rotating assembly according to an 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 shell 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 shell 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 shell 1, and the 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; by adopting the above scheme, the electronic flash therapy shell 2 can irradiate at multiple angles: the electron beam generated by the high-energy electron accelerator 100 located in the electronic flash therapy shell 2 can swing at an angle of plus or minus 45 degrees, which can adapt to different lesion sites and treatment needs, and improve the accuracy of treatment.

[0033] The electronic flash therapy device base 1 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 positioning seat 10 and the support frame 11 improve the stability and safety of the entire device, and at the same time, also improve the 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 seat 20 is fixedly provided on one side of the electronic flash therapy housing 2 close to the support frame 11, and a rotating assembly 4 is installed between the support frame 11 and the rotating seat 20; specifically, the rotating assembly 4 includes a rotating shaft 42, and support bearings 40 are installed at both ends of the rotating shaft 42. A microwave tube 41 with a variable angle is installed in the rotating shaft 42, wherein the support bearing 40 is concentrically arranged with the microwave tube 41. Such a structural design ensures the stability and accuracy 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 in the hollow tube; for the electron flash therapy shell 2, preferably, it can be designed into a pipe shape, based on which the electrons with a divergent angle in the high-energy electron accelerator 100 can be quickly transmitted to the end to treat the irradiated part 3.

[0038] In addition, the high-energy electron accelerator 100 directly irradiates the irradiation site 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, thereby shortening the treatment cycle.

[0039] The electronic flash therapy head 200 can be detachably mounted 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 the 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 the 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 carry out 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] Embodiment 2:

[0043] like Figure 5-Figure 6 As shown, Figure 5 is a front view of the second embodiment of the present invention; Figure 6 is a structural diagram of Embodiment 2 of the present invention;

[0044] The variable-angle electronic flash therapy device comprises an electronic flash therapy device base 1; an electronic flash therapy shell 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 shell 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 shell 1, and the 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; and a guide rail 300, which is located between the electronic flash therapy device base 1 and the electronic flash therapy shell 2 and is used to adjust the positional relationship between the electronic flash therapy shell 2 and the irradiation site 3.

[0045] By adopting the above scheme, the electron flash therapy shell 2 can 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 allows 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, the angle swing range of plus or minus 45 degrees can more accurately irradiate the lesion while reducing damage to surrounding normal tissues.

[0047] The above structural design enables the device to cooperate with the electronic flash therapy housing 2 to complete the electron beam irradiation function at multiple angles and different heights. The realization of this function can greatly improve the effect of electronic flash therapy and provide patients with more accurate and effective treatment; for some irregularly shaped tumors, by adjusting the angle and height of the electronic flash therapy housing 2, all-round irradiation of the tumor can be achieved, thereby improving the cure rate.

[0048] The electronic flash therapy device base 1 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 positioning seat 10 and the support frame 11 improve the stability and safety of the entire device, and at the same time, also improve the 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, and a guide groove 13 is formed inside the support frame 11. The guide rail 300 is an arc-shaped structure, and the guide rail 300 is built in the guide groove 13 and moves along the guide groove 13. In this embodiment, by setting the guide rail 300, an arc-shaped sliding can be generated between the bracket with the arc guide rail 300 and the support frame 11, so that the electron flash therapy housing 2 can be slid to different levels. In this way, the electron beam in the high-energy electron accelerator 100 can be irradiated at different heights, further improving the flexibility and adaptability of the treatment.

[0050] For example, when treating tumors in different parts of the body, the height of the electron flash therapy housing 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 this embodiment is as follows:

[0052] 1. Install the electronic flash therapy device base 1 in a suitable position to 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, install the variable-angle microwave tube 41 and the support bearing 40 concentrically on the rotating shaft 42, and connect the electron flash therapy housing 2, the high-energy electron accelerator 100 and the electron flash therapy head 200.

[0054] 3. Finally, debugging is performed 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 electron flash therapy housing 2 can smoothly slide to different levels on the bracket with the curved guide rail 300.

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

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

[0057] 2. Then, according to the height of the lesion, the electronic flash therapy housing 2 is slid to a corresponding horizontal height through the bracket with the curved guide rail 300.

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