Description

Technical Field

[0001] The present invention relates to the technical field of tumor radiotherapy, and in particular to an auxiliary imaging device for tumor radiotherapy. Background Art

[0002] Auxiliary imaging devices for tumor radiotherapy are mainly used to provide high-precision image guidance during radiotherapy to ensure that the radiation can be accurately irradiated to the tumor site while minimizing the impact on surrounding healthy tissues.

[0003] During tumor radiotherapy, precise patient positioning and fixation are crucial to ensure the effectiveness and safety of treatment. However, in actual practice, many medical institutions do not fully apply effective limiting measures when performing radiotherapy on patients, resulting in slight body movements of patients during treatment, especially in areas such as the head, neck or chest that are easily affected by breathing or other physiological activities. These tiny movements will introduce motion artifacts during the imaging process. Motion artifacts will cause the edges of the image to become unclear, making it difficult for doctors to accurately distinguish between the tumor boundary and the surrounding healthy tissue, thus affecting the accuracy of diagnosis.

[0004] In view of the above problems, it is necessary to design an auxiliary imaging device for tumor radiotherapy that limits the position of the patient's body. Summary of the invention

[0037] like Fig.11 As shown, it also includes a push-up mechanism 8, which is arranged on the upper side of the support plate 401. The push-up mechanism 8 includes a connecting rod 801, a guide plate 802, an inclined plate 803, a guide rod 804, a screw 805 and an extrusion block 806. The front and rear sides of the outer side of the pillow pad 403 are symmetrically connected to the connecting rod 801. The movement of the connecting rod 801 can drive the pillow pad 403 to move. The front and rear sides of the outer side of the support plate 401 are symmetrically connected to the guide plate 802. The connecting rod 801 and the guide plate 802 are slidably matched. The guide plate 802 provides a sliding path for the connecting rod 801. The bottom of the pillow 403 is connected with an inclined plate 803, and the right side of the support plate 401 is symmetrically connected with a guide rod 804, the guide rod 804 can provide a sliding path for the extrusion block 806, and the right side of the support plate 401 is threadedly connected with a screw rod 805, and the screw 805 is slidably connected with an extrusion block 806, the extrusion block 806 is slidably connected to the two guide rods 804, the extrusion block 806 moves to contact the inclined plate 803, and lifts up the inclined plate 803, so as to facilitate the adjustment of the height of the pillow 403 and ensure that the patient's head is at the most suitable treatment height.

[0038] During the process of tumor radiotherapy, when the device is needed for auxiliary imaging, before starting the tumor radiotherapy, the patient needs to take off his shoes and lie flat on the mattress 402 on the treatment bed 3, with his head resting on the special pillow 403. Then the doctor turns the screw 805 to make the screw 805 rotate. The rotation of the screw 805 drives the extrusion block 806 to move to the left along the two guide rods 804. The extrusion block 806 moves to contact the inclined plate 803 and lift it up, causing the inclined plate 803 to drive the pillow 403 and the two connecting rods 801 to move upward along the corresponding guide plates 802. When the patient's head is at the most suitable treatment height, the screw 805 is stopped. Then the doctor connects a small suction pump to the flange interface. After the pump is connected externally, the doctor opens the multiple valves 407 and starts the small suction pump at the same time. The suction force generated by the small suction pump causes the gas in the multiple air bags 405 to be pumped into the corresponding connecting tubes 406, and then pumped into the air inlet pipe 409 through the corresponding connecting tubes 406, and then pumped into the small suction pump and discharged, so that the multiple air bags 405 gradually fit the patient's head and body contours, and adjust the tightness of the multiple air bags 405 according to the patient's body shape to provide the best support and fixation effect. When the tightness of the multiple air bags 405 is adjusted, the multiple valves 407 are closed, and the small suction pump is turned off and disassembled. Then the doctor pulls the strap 603 to pass through the fixing groove on the lower side of the second fixing block 604, the buckle 602, and the second The doctor then moves the first hinged plate 504 and the second hinged plate 504 to the treatment bed 3. The doctor then moves the first hinged plate 504 and the second hinged plate 504 to the treatment bed 3. The doctor then moves the first hinged plate 504 and the second hinged plate 504 to the treatment bed 3. The doctor then moves the first hinged plate 504 and the second hinged plate 504 to the treatment bed 3. The doctor then moves the first hinged plate 504 and the second hinged plate 504 to the treatment bed 3. The second connecting plate 707 moves to the left, and the spring 710 is stretched. At this time, the extrusion rod 709 applies pressure to the rotating frame 704, causing the rotating frame 704 to rotate along the first connecting plate 703, and the torsion spring 706 is deformed until the rotating frame 704 rotates to contact and fit with the patient's chest. When the respiratory curve acquisition module 506 moves above the patient's chest, the electric slide rail 502 is closed, and then the doctor presses the button 508 to activate the respiratory curve acquisition module 506, so that the probe 507 starts to move downward until the probe 507 lightly touches the patient's chest. Once the probe 507 fits with the patient's chest, the probe 507 starts to monitor and record the patient's breathing process and generate a respiratory curve. These data are immediately transmitted to the monitoring terminal used by the doctor.This allows the doctor to view the breathing curve in real time during the treatment. When the doctor observes that the patient's breathing curve tends to be stable and flat, it indicates that the patient is in an ideal breathing state. Then the treatment bed 3 automatically drives the support plate 401 and all the components thereon to move to the right. When the patient's head moves to the bottom of the tumor emission treatment device 2, the treatment bed 3 stops moving. Then the doctor starts the tumor emission treatment device 2. The tumor emission treatment device 2 first performs a high-precision scan on the patient's head to obtain detailed images of the tumor and its surrounding structures. These images will be transmitted to the doctor's monitoring terminal in real time for verification and adjustment of the treatment plan. After the doctor confirms that the location of the tumor is correct, the doctor starts the built-in Linear accelerator, the linear accelerator starts to emit high-energy X-rays to the patient's head. High-energy X-rays can penetrate tissues to reach the tumor location. After the high-energy X-rays reach the tumor cells, they will release energy to destroy the DNA structure of cancer cells, prevent their growth or cause cell death, and minimize the impact on surrounding healthy tissues. After the treatment is over, the doctor turns off the tumor emission treatment device 2 and the linear accelerator, and the treatment bed 3 automatically drives the support plate 401 and all components thereon to move to the left. When the treatment bed 3 moves to the initial position, the treatment bed 3 automatically closes, and then repeats the opposite operation of limiting the patient, so that the patient is no longer restricted from moving. Then the doctor carefully checks the patient's condition and safely transfers the patient to the ward for rest. ,
