[0002] Radiation therapy is one of the three major methods for treating tumors and plays a vital role in tumor treatment. Teaching radiation therapy for tumors to medical students is extremely important and necessary.
[0003] Intensity-modulated radiotherapy (IMRT) is an advanced technology in the field of radiotherapy. IMRT medical devices adjust the angle and intensity of the radiation beams to make the high-dose area match the shape of the tumor, while the surrounding normal tissues receive a lower radiation dose.
[0004] However, because radiotherapy equipment cannot be truly demonstrated in the classroom and there is a lack of corresponding teaching aids in the existing technology, students lack an intuitive understanding of intensity-modulated radiotherapy (IMRT) and find it difficult to comprehend the principles of IMRT by relying solely on the teacher's verbal explanation. Summary of the Invention

[0017] It should be noted that, unless otherwise specified, all components in this invention are known in the prior art. For example, the laser light uses a commonly known laser light.
[0018] The following are specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments. All equivalent modifications made based on the technical solutions of this application fall within the protection scope of the present invention.
[0019] In existing technologies, tumor treatment equipment includes external beam radiation therapy (EPR) devices, which are also the main radiotherapy equipment.
[0020] Existing radiotherapy equipment includes a treatment gantry, specifically a bed for the patient to lie on, with a ring frame fixedly mounted on one side of the bed. An annular track is provided within the inner circle of the ring frame, and at least one sealed radiation head is slidably mounted on the track. The radiation head is a linear accelerator, and when the patient is lying on the bed, the area requiring treatment is located at the center of the ring frame. The radiation head delivers radiotherapy to the area requiring treatment. It rotates 360 degrees around the patient, continuously emitting fan-shaped rays to irradiate the tumor from multiple angles and in all directions. Throughout this process, the patient remains stationary.
[0021] Because radiotherapy equipment cannot be truly demonstrated in the classroom, existing technologies lack corresponding teaching aids. However, the intensity-modulated radiotherapy (IMRT) demonstration teaching aid for classroom teaching of tumor radiotherapy proposed in this application can intuitively demonstrate the principles of IMRT technology. By changing the number of radiation sources and the fixing and movement of the radiation sources, it can deepen students' understanding of IMRT methods.
[0022] Based on existing radiotherapy equipment, the following is a simplified radiotherapy teaching aid for classroom instruction according to this embodiment: like Figure 1 As shown, a simple radiotherapy teaching aid for classroom teaching includes a base 1, on which a fixing ring 2 is detachably mounted; The inner ring of the fixed ring 2 is provided with an annular track 3, the outer diameter of the annular track 3 matches the inner diameter of the fixed ring 2, and the bottom of the annular track 3 is provided with an opening; the bottom of the inner ring of the fixed ring 2 is also provided with a base 4, and the bottom of the base 4 enters the opening of the annular track 3 and is detachably connected to the bottom of the inner ring of the fixed ring 2. The base 4 is a quadrangular pyramid shape, and the bottom of the base 4 has an arc, which matches the arc of the inner ring of the fixing ring 2. A target ball 5 is set on the top of the base 4, and the center of the target ball 5 and the center of the fixed ring 2 are at the same point.
[0023] A sliding block 6 is slidably mounted on the circular track 3, and a laser light 7 is mounted on the sliding block 6.
[0024] The target ball 5 simulates the irradiated target. It slides on the circular track 3 via the slider 6, changing the irradiation direction of the laser lamp 7 to simulate the adjustment of different angles of the beam in intensity-modulated radiotherapy (IMRT). Changing the specifications of the laser lamp 7 allows for the simulation of beams of different intensities, deepening students' understanding of IMRT.
[0025] In addition, this device has a convenient structure, is easy to install and disassemble, and is convenient for intuitively demonstrating the principles and conducting teaching in the classroom, making it suitable for large-scale use and promotion.
[0026] The following provides a further explanation of how the device in this embodiment enables classroom teaching: The above content mentions that: the device in this embodiment uses the target sphere 5 to simulate the part of the human body that requires radiotherapy. During the treatment process, the human body is fixed, so the device in this embodiment is equipped with a target ball 5 fixed on the top of the base 4, wherein the base 4 plays a supporting role, and the target ball 5 is used to simulate the part of the human body that needs radiotherapy.
[0027] Based on this, the fixed ring 2 is used to simulate the ring frame of the radiotherapy equipment, and the ring track 3 opened in the inner circle of the fixed ring 2 is used to simulate the track of the inner circle of the ring frame. The target ball 5 is set with the fixed ring 2 at the same center, which is consistent with the location of the human body that needs radiotherapy and the position of the ring frame in the prior art.
[0028] Next, a laser lamp 7 is used to simulate the radiation head of a radiotherapy device. The laser lamp 7 can slide on the annular track 3 along with the sliding block 6, which is consistent with the fact that the radiation head in the prior art can slide on the track in the inner circle of the annular frame.
[0029] In summary, the device of this embodiment provides a suggested simulation of existing radiotherapy equipment, simplifying the core principles of radiotherapy equipment and making it suitable for teachers to demonstrate the operating principles of the device to students in the classroom. Since the overall operating logic of the device and the coordination between its parts are similar to those of actual treatment equipment, those skilled in the art can understand the connection between the device of this embodiment and actual treatment equipment in terms of core principles.
[0030] As a preferred option, such as Figure 3 and Figure 4 As shown, the base 1 has a mounting slot 8; The bottom of the fixing ring 2 is fixedly connected to a mounting block 9 that matches the mounting groove 8.
[0031] In use, the retaining ring 2 can be detachably installed inside the mounting groove 8 of the base 1 via the mounting block 9.
[0032] As a preferred option, such as Figure 2As shown, multiple sliding blocks 6 are slidably arranged on the circular track 3.
[0033] This setup allows for the simultaneous installation of several sliding blocks 6 on the circular track 3, with the distance between each sliding block 6 being adjustable. This further simulates the actual operation scenario, facilitating teacher explanation and student comprehension.
[0034] As a specific implementation method, such as Figure 6 As shown, the slider 6 has an arc, and the arc of the slider 6 matches the arc of the circular track 3; this arrangement makes it easier to connect the slider 6 and the circular track 3.
[0035] The bottom of the sliding block 6 is provided with a sliding groove 10 that matches the annular track 3, and the sliding block 6 is slidably connected to the annular track 3 through the sliding groove 10.
[0036] Further preferably, handles 11 are installed on both sides of the upper end face of the sliding block 6. This facilitates the operator's movement of the sliding block 6.
[0037] As a preferred embodiment, the laser lamp 7 is connected to a laser lamp switch. The laser lamp switch is used to control the laser lamp's on / off state.
[0038] Specifically, base 1 is a truncated quadrangular shape to ensure the stability of the overall device.
