[0018] Embodiment 1

[0019] This embodiment provides a whole body fixation device for radiotherapy of pediatric tumors. Please refer to Figures 1-6 , which includes a base 1, a vacuum negative pressure bag 2, a body handle 107 and a leg splitter 108; the base 1 has a head, neck and shoulder fixing position 109, a chest and abdomen fixing position 110, a pelvic cavity fixing position 111 and a lower limb fixing position 112 arranged in sequence; the head, neck and shoulder fixing position 109 is used for detachably placing a headrest; a plurality of vacuum negative pressure bags 2 are arranged and can be detachably placed on the head, neck and shoulder fixing position 109, the chest and abdomen fixing position 110, the pelvic cavity fixing position 111 and the lower limb fixing position 112; a plurality of body handles 107 are arranged and can be detachably arranged on both sides of the base 1; the leg splitter 108 can be detachably arranged on the base 1 and is used for separating the legs of the patient.

[0020] On the base 1, a head-neck-shoulder fixation position 109, a chest-abdomen fixation position 110, a pelvic fixation position 111, and a lower limb fixation position 112 are sequentially arranged. A headrest is detachably arranged at the head-neck-shoulder fixation position 109 for fixing the head; and vacuum negative pressure bags 2 are detachably arranged at the head-neck-shoulder fixation position 109, the chest-abdomen fixation position 110, the pelvic fixation position 111, and the lower limb fixation position 112, which can fix the whole body or local postures of the patient as needed; by detachably arranging body handles 107 on both sides of the base 1, it is convenient for the patient to hold for body fixation; a leg separator 108 is detachably arranged, which can separate the patient's legs for leg fixation; thus, local fixation or whole body fixation can be carried out as needed, improving adaptability and flexibility; a scale is arranged on the periphery of the base, which is convenient for medical staff to determine the size.

[0021] Specifically, the headrest is fixed by a fixing pin 105. The vacuum negative pressure bag 2 is set as a conventional structure. Negative pressure is pumped through the air nozzle 21, and then the patient's body is fixed. It can be set to three. One is covered on the head-neck-shoulder fixation position 109, the chest-abdomen fixation position 110, and the pelvic fixation position 111, as Figure 4 and Figure 6 shown, and there are holes for the leg separator 108 to pass through on it. The other two are covered on the lower limb fixation position 112 to fix the lower limbs, as Figure 5 and Figure 6 shown;

[0022] Furthermore, the head-neck-shoulder fixation position 109 is also used for detachably placing a head-neck-shoulder fixation film; the chest-abdomen fixation position 110 and / or the pelvic fixation position 111 are used for detachably setting a body fixation film. The leg separator 108 can be detachably connected to the body fixation film; the lower limb fixation position 112 is used for detachably setting a lower limb fixation film; by setting the head-neck-shoulder fixation film, the body fixation film, and the lower limb fixation film as needed, it further plays a role in fixing the patient; specifically, a first fixing hole 101 is arranged on the head-neck-shoulder fixation position 109 to be detachably connected to the head-neck-shoulder fixation film, a second fixing hole 102 is arranged on the chest-abdomen fixation position 110 and the pelvic fixation position 111 to be detachably connected to the body fixation film, and the lower limb fixation position 112 is detachably connected to the lower limb fixation position 112 through a third fixing hole 103.

[0023] Furthermore, fixing strips 106 are also arranged on the chest-abdomen fixation position 110 and / or the pelvic fixation position 111. By arranging the fixing strips 106 on the chest-abdomen fixation position 110 and the pelvic fixation position 111, they can be embedded into the outer wall of the vacuum negative pressure bag 2 after the vacuum negative pressure bag 2 is pumped with negative pressure to fix the vacuum negative pressure bag 2 and prevent it from shifting; a head handle 104 is arranged on the head-neck-shoulder fixation position 109, which is convenient for the patient to grab or limit the fixation of the head.

[0024] Furthermore, please refer to Figure 2, the body handle 107 is composed of a handle body 1071, a handle base 1072 and a locking knob 1073. The handle base 1072 has a locking groove 1074 for embedding and mating with the flash 113. The locking knob 1073 is threadedly connected to the handle base 1072. Rotating the locking knob 1073 moves the lower end of the locking knob 1073 up and down so as to be able to press against or disengage from the flash 113, thereby realizing the locking and unlocking of the body handle 107 and the flash 113.

[0025] Further, please refer to Figure 3 , the leg splitter 108 is composed of an eccentric knob 1081, a floating shaft 1082, a fixed column 1083 and a leg splitter base 1084. The eccentric knob 1081 is rotatably connected to the leg splitter base 1084. When the eccentric knob 1081 is in the vertical state, the floating shaft 1082 and the fixed column 1083 are aligned with the stepped hole 114 of the base 1 and inserted. Rotating the eccentric knob 1081 to the horizontal state, the rotation of the eccentric button drives the floating shaft 1082 to move vertically and clamp in the stepped hole 114. At this time, rotating the eccentric knob 1081 is in the locked state, and the leg splitter 108 is fixed on the base 1; a film buckling hole 1085 capable of detachably connecting with the body fixing film is further provided on the leg splitter base 1084; for the structure of the stepped hole 114, please refer to Figure 7 , the upper half of the stepped hole 114 has a small diameter, and the lower half has a large diameter. Silicone rings are provided on the outer peripheries of the lower ends of the floating shaft 1082 and the fixed column 1083, and can be fixed when the silicone rings are embedded in the large-diameter part of the stepped hole 114.

[0026] In the present utility model, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model.
