Description

Technical Field

[0001] The invention belongs to the technical field of medical body position fixation, and in particular relates to a patient body position fixation device for tumor radiotherapy. Background Art

[0002] Tumor radiotherapy is a local treatment method that uses radiation to treat tumors. The duration of a single radiotherapy session varies from a few minutes to more than ten minutes depending on the situation. The so-called fixation is to minimize the patient's movement during the treatment process, which will cause changes in body position and affect the accuracy of radiotherapy.

[0003] Traditional equipment does not have perfect fixation during use. For example, the legs or head are not fixed. If the patient moves during radiotherapy, it may cause overall errors. At the same time, traditional equipment cannot fix patients of different body shapes. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a patient position fixation device for tumor radiotherapy to solve the problems raised in the above background technology.

[0005] In the first aspect, to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a patient position fixation device for tumor radiotherapy, comprising a lying board and two groups of leg fixation mechanisms, one side of the lying board is fixedly connected with a rotating shaft fixing frame, the inner wall of the rotating shaft fixing frame is rotatably connected with a rotating shaft body, the outer walls of the rotating shaft body are movably connected with the inner walls of the leg fixation mechanisms, the outer wall of the rotating shaft body is fixedly connected with a fixing frame body, the inner wall of the fixing frame body is fixedly connected with a trunk fixing device, and there are four groups of trunk fixing devices.

[0006] Each group of the leg fixing mechanisms includes a driven transmission belt, the inner wall of each group of the driven transmission belt is transmission-connected to the outer wall of the rotating shaft body, each group of the inner wall of the driven transmission belt is transmission-connected to a steering bevel gear, each group of the steering bevel gear is provided with a transmission bevel gear at one end, the teeth of each group of the steering bevel gear are meshed with the teeth of the transmission bevel gear, each group of the outer wall of the transmission bevel gear is transmission-connected to a transmission transmission belt, each group of the inner wall of the transmission transmission belt is transmission-connected to a rotating shaft body, and there are four groups of rotating shaft bodies, each group of the inner wall of the rotating shaft body is fixedly connected to a meshing gear, the teeth of every two groups of the meshing gears are meshed with each other, the inner wall of the rotating shaft body is transmission-connected to a tightening belt, and each group of the outer wall of the rotating shaft body is rotationally connected to a rotating shaft fixing frame.

[0007] Each group of the torso fixing device includes a storage box, and there are eight groups of storage boxes in total. Each group is located on the inner wall of the storage box and is rotatably connected to a clockwork spring shaft, each group is located on the outer wall of the clockwork spring shaft and is fixedly connected to a clockwork spring body, and each group is located on one end of the clockwork spring body and is fixedly connected to an elastic fixing belt.

[0008] Through the above technical scheme, a more stable fixation effect can be achieved. When the patient enters the equipment, the fixing frame body is rotated to drive the rotating shaft body to rotate, and the driven transmission belt is driven to transmit the power, and at the same time, the driven transmission belt drives the steering bevel gear to rotate. Since the steering bevel gear is meshed with the transmission bevel gear, the transmission bevel gear will also rotate, and drive the transmission transmission belt to transmit the power, so that the rotating shaft body and the meshing gear rotate. Since the two sets of meshing gears rotate in opposite directions, the two sets of rotating shaft body bodies rotate in opposite directions, and the contraction of the tightening belt can be controlled. Through the setting of the clockwork spring body and the elastic fixing belt, it can be drawn out when needed to adapt to patients of different body shapes, thereby increasing the applicability of different patients.

[0009] Preferably, the outer wall of each group of the tightening belts is transmission-connected with a slider, and there are four groups of sliders in total, every two groups of sliders are slidably connected to each other, and the outer wall of each group of sliders is slidably connected to the inner wall of the fixing frame body.

[0010] Through the above technical solution, the effect of adapting to different patients is achieved. Through the setting of the slider, when the tightening belt contracts, the slider will be driven to move inward, and at the same time, the width of the tightening belt is reduced, so that it can adapt to different patients, further increasing the stability and applicability of fixation.

[0011] Preferably, the outer wall of the fixing frame body is fixedly connected with a support frame, and there are two groups of support frames, the top of each group of support frames is fixedly connected to the bottom of the rotating shaft fixing frame, and each group of outer walls located on the tightening belt are fixedly connected with a limiting block.

[0012] Through the above technical solution, the effect of increasing safety is achieved. The leg fixing mechanism is fixed on the surface by the setting of the support frame to avoid personal injury caused by falling out. The limiting block is set to prevent the restraining belt from detaching, thereby increasing the safety of the equipment.

[0013] Preferably, a neck pillow is fixedly connected to the outer wall of the lying board, a leg pillow is fixedly connected to the outer wall of the lying board, and an audio speaker is fixedly connected to the inner wall of the lying board.

[0014] Through the above technical solution, the effect of relaxing the patient is achieved. The setting of the neck pillow and the leg pillow makes the patient's experience during use more comfortable. The setting of the audio speakers allows the patient to relax and reduce tension.

[0015] Preferably, a lifting device is fixedly connected to the bottom of the lying board, and a moving device is rotatably connected to the bottom of the lifting device.

[0016] Through the above technical solution, the effect of convenient positioning is achieved. The lifting device can be used for lifting and lowering, so that the patient does not need auxiliary equipment when getting on the equipment. At the same time, the height is automatically adjusted during the alignment operation, thereby achieving more accurate radiotherapy. The equipment can be moved through the setting of the moving device, thereby achieving better positioning and reducing the possibility of errors.

[0017] Preferably, a head fixing device is fixedly connected to the top of the lying board.

[0018] Through the above technical solution, the effect of fixing the head is achieved. The patient's forehead can be fixed by setting the head fixing device. The inner wall is provided with a sponge pad. The flexible clamping will not hurt the patient and the error caused by the patient's movement can be minimized.

[0019] In the second aspect, the technical solution proposed in accordance with the first aspect further proposes: a method for using a patient position fixation device for tumor radiotherapy, comprising the following steps:

[0020] S1. Operate the leg fixation mechanism, head fixation device and torso fixation device to fix the patient.

[0021] a1. During operation, the rotating shaft body is driven to rotate by rotating the fixing frame body, and the driven transmission belt is driven to drive the steering bevel gear. Since the steering bevel gear is meshed with the transmission bevel gear, the transmission bevel gear will also rotate, and drive the transmission belt to drive, so that the rotating shaft body and the meshing gear rotate. Since the two sets of meshing gears rotate in opposite directions, the two sets of rotating shaft body bodies rotate in opposite directions, and the contraction of the tightening belt can be controlled. Through the setting of the main body of the spring and the elastic fixing belt, it can be drawn out when needed;

[0022] a2. Through the setting of the slider, when the tightening belt shrinks, it will drive the slider to move inward, and at the same time achieve the effect of reducing the width of the tightening belt;

[0023] a3. The patient's forehead can be fixed by the setting of the head fixing device. The inner wall is provided with a sponge pad. The flexible clamping will not hurt the patient and minimize the error caused by the patient's movement.

[0024] S2. Operate the lifting device and moving device to perform alignment operations.

[0025] b1. The device can be raised and lowered so that the patient does not need auxiliary equipment when getting on the device. The height can be automatically adjusted during the alignment operation, thus achieving more accurate radiotherapy.

[0026] b2. The device can be moved by setting up a mobile device, thereby achieving better positioning and reducing the possibility of error.

[0027] S3. Treat the patient with radiation therapy.

[0028] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0029] 1. The present invention provides a patient position fixing device for tumor radiotherapy, which drives the rotating shaft body to rotate by rotating the fixing frame body, and drives the driven transmission belt to transmit, and at the same time, the driven transmission belt drives the steering bevel gear to rotate. Since the steering bevel gear is meshed with the transmission bevel gear, the transmission bevel gear will also rotate, and drive the transmission transmission belt to transmit, so that the rotating shaft body and the meshing gear rotate. Since the two groups of meshing gears rotate in opposite directions, the two groups of rotating shaft body bodies rotate in opposite directions, and the contraction of the tightening belt can be controlled. Through the arrangement of the clockwork spring body and the elastic fixing belt, it can be drawn out when needed to adapt to patients with different body shapes, thereby increasing the applicability of different patients.

[0030] 2. Through the setting of the slider, when the contraction belt is contracted, the slider will be driven to move inward, and at the same time the width of the contraction belt is reduced, so that it can adapt to different patients, further increasing the stability and applicability of fixation.
