Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a fixing device for assisting in fixing the position of hips and legs for radiotherapy. Background Art

[0002] The supine position is one of the most common positions. The patient lies flat on the bed with the back close to the bed surface, and the head, neck, chest, abdomen, buttocks and legs are naturally stretched. This position is suitable for many pelvic or abdominal and lower limb radiotherapy. For example, for tumors in the pelvic cavity such as cervical cancer, rectal cancer, or soft tissue tumors in the thigh, the supine position can facilitate the accurate irradiation of the tumor from different angles above or around.

[0003] When the user is in a supine position, the user's lower limbs are required to be separated and lifted so that the part of the user's pelvis or abdomen that needs radiotherapy is exposed for radiotherapy. In the prior art, most of them directly adjust the supports on both sides of the end of the bed to an appropriate height, and the user lies on the bed and directly places the lower limbs on the supports for support. In this way, the position of the user's hips and legs is fixed, so that the part of the user's pelvis or abdomen that needs radiotherapy is exposed to the treatment environment for treatment. However, when the user's legs are placed on a support with a height for a certain period of radiotherapy, the user's legs will be lifted up for a long time, and maintaining the same action will cause the blood circulation in the user's legs to be too slow, and the legs will also become numb, which will cause the user's legs to be easily uncomfortable.

[0019] The present invention has the following beneficial effects:

[0020] 1. After the user's thigh near the knee joint is placed on the thigh placement frame of the present invention, the calf will be bent through the knee joint, so that the patient's calf is placed on the calf support wheel. During the user's radiotherapy, the electric push rod drives the connecting strip, the sliding hole frame, the sliding frame, the upper extension frame and the calf support wheel to rise and fall reciprocatingly. By placing the user's calf on the calf support wheel, the calf support wheel rolls on the user's calf and is dragged to the joint of the calf and thigh to move back and forth, thereby promoting blood circulation in the legs, reducing the discomfort of the patient's lower limbs caused by the user's leg joint being kept in one position for a long time, thereby improving the user's comfort when the hip and leg are fixed during radiotherapy, and after the mobile positioning frame is adjusted inside the lifting frame, the control strip is pulled to make the stretching slide bar slide down inside the contraction hole at the bottom of the connecting strip, and the connecting spring between the top of the stretching slide bar and the connection of the connecting strip is stretched, so that the positioning rod 2 is separated from the positioning hole 2, and the sliding frame is pushed to slide inside the sliding hole frame, so that the calf support wheel is adjusted accordingly according to the length of the user's calf after the mobile positioning frame is adjusted.

[0021] 2. In the present invention, when the user's lower limbs are placed on the thigh placement frame and separated, the motor drives the screw rod to rotate inside the moving groove, driving the sliding block to slide inside the moving groove, and the pushing bar is rotatably connected with the sliding block. The initial angle between the pushing bar and the sliding block is greater than thirty degrees. When the sliding block slides to the side away from the motor, the angle between the pushing bar and the sliding block will gradually increase, and then the arc-shaped pushing frame will push the two lifting frames to rotate on the two rotating connecting heads respectively, so that the end of the lifting frame away from the main body will tilt upward, and then the lifting mechanism and the leg separation mechanism can be driven to lift up, so as to lift the user's lower limbs, thereby making it convenient for the user to expose the pelvic or abdominal area that needs radiotherapy for radiotherapy. In this way, the user's legs are lifted, so that the legs can be moved through the joints of the thighs and the upper body. When the lower limbs are lifted during exercise, the upper body lying on the sliding board will generate a forward thrust, and the sliding column is driven by the user's upper body to move accordingly to the side of the lifting frame inside the movable groove according to the lifting range of the lower limbs. Not only can the patient's pelvis or abdomen that needs to be exposed for radiotherapy continue to move forward with the upper body, the bending range of the thighs and upper body is increased, and the range of the pelvis or abdomen exposed to the outside is increased, but it can also reduce the bending range of the user's upper body after the legs are lifted, so that the patient's waist is close to the top of the sliding board, and the patient's comfort after the lower limbs are lifted. The sliding column and the inner wall of the cylindrical groove have a friction resistance greater than the elastic force of the tension spring, so that after the sliding board moves inside the movable groove, when no external force is applied, the sliding board will not swing back and forth inside the movable groove.

[0022] 3. The present invention controls the manual screw rod to rotate, thereby driving the connection between the movable positioning frame and the adjusting slide groove to move inside the adjusting slide groove, adjusting the position of the movable positioning frame to the corresponding position, and then adjusting the position of the thigh placement frame so that a part of the user's thigh close to the joint is placed inside the thigh placement frame. After the patient lies on the top of the sliding reclining board, a part of the thigh close to the joint is placed inside the thigh placement frame. The position of the thigh placement frame can be adjusted according to the length of the user's thigh, and the handle frame is pulled downward to separate the positioning rod one from the positioning hole one. After the sliding frame loses the positioning force, the rotating frame can slide inside the strip sliding hole through the sliding frame, thereby relatively adjusting the positions of the two sets of thigh placement frames. After the adjustment is completed, the handle frame is released and the position is adjusted by pulling The restoring spring on the inner wall of the top of the extension slide and the retraction hole pulls the handle frame to reset. When the hole at the bottom of the sliding frame corresponds to one of the groups of positioning holes, the handle frame is reset and the positioning rod is inserted into it, thereby positioning the rotating frame of the adjustment axis, so that the spacing between the two groups of thigh placement frames can be adjusted according to the degree of separation required for the user's legs, and can be adjusted according to the user's height or leg length. After the two groups of thigh placement frames are adjusted, the patient's two lower limbs will be separated. Through the rotational connection between the thigh placement frame and the top of the rotating frame, the direction of the thigh placement frame can be adjusted accordingly during the process of relative adjustment of the two rotating frames on the top of the two moving positioning frames, so that the position of the thigh placement frame is in a straight line with the position of the patient's thigh, thereby improving the patient's comfort.

When the sliding block 309 slides to the side away from the motor 310, the angle between the push bar 308 and the sliding block 309 will gradually increase, and then the arc-shaped push frame 307 will push the two lifting frames 301 to rotate on the two rotating connectors 108 respectively, so that the end of the lifting frame 301 away from the main body 1 is tilted upward, and then the lifting mechanism 3 and the leg separation mechanism 4 can be driven to lift up, so as to lift the user's lower limbs and make the user's pelvis that needs radiotherapy be lifted. The pelvic cavity or abdomen of the patient who needs to be exposed for radiotherapy is exposed to carry out radiotherapy. In this way, the user's legs are lifted up, and when the legs move through the joints of the thighs and the upper body and the lower limbs are lifted up, the upper body lying on the sliding reclining board 204 will generate a forward thrust, and the sliding column 201 is driven by the upper body of the user to move in the movable groove 101 to one side of the lifting frame 301 according to the lifting amplitude of the lower limbs, which can not only make the pelvic cavity or abdomen of the patient who needs to be exposed for radiotherapy continue to move forward with the upper body, but also increase the bending amplitude of the thigh and the upper body, and the sliding column 201 and the inner wall of the cylindrical groove 103 have a friction resistance greater than the elastic force of the tension spring 203, so that after the sliding reclining board 204 moves in the movable groove 101, when no external force is applied, the sliding reclining board 204 will not swing back and forth in the movable groove 101;

[0043] By controlling the manual screw rod 303 to rotate, the connection between the movable positioning frame 304 and the adjusting slide groove 302 is driven to move inside the adjusting slide groove 302, and the position of the movable positioning frame 304 is adjusted to the corresponding position, and then the position of the thigh placement frame 402 is adjusted, so that the user's thigh near the joint is placed inside the thigh placement frame 402. After the patient lies on the top of the sliding reclining board 204, the thigh near the joint is placed inside the thigh placement frame 402. The position of the thigh placement frame 402 can be adjusted according to the length of the user's thigh, and the handle frame 405 is pulled downward to separate the positioning rod 1 406 from the positioning hole 1 306. After the sliding frame 401 loses the positioning force, the rotating frame 4011 can slide inside the strip sliding hole 305 through the sliding frame 401, thereby relatively adjusting the positions of the two sets of thigh placement frames 402. After the adjustment is completed, the handle frame is released. 405, by stretching the slider 404 and the return spring on the top inner wall of the shrinkage hole 4012, the handle frame 405 is pulled to reset. When the hole at the bottom of the sliding frame 401 corresponds to one of the positioning holes 306, after the handle frame 405 is reset, the positioning rod 406 is inserted therein, thereby positioning the rotating frame 4011 of the adjustment axis, so that the spacing between the two groups of thigh placement frames 402 can be adjusted according to the degree of separation required for the user's legs, and can be adjusted according to the user's height or leg length. After the two groups of thigh placement frames 402 are adjusted, the patient's two lower limbs will be separated. Through the rotation connection between the thigh placement frame 402 and the top of the rotating frame 4011, the direction of the thigh placement frame 402 can be adjusted accordingly during the process of relative adjustment of the two rotating frames 4011 at the top of the two movable positioning frames 304, so that the position of the thigh placement frame 402 is in a straight line with the position of the patient's thigh.
