Description

Technical Field

[0001] The utility model relates to the technical field of pelvic radiotherapy fixators, in particular to a portable fixator. Background Art

[0002] The main purpose of the pelvic radiotherapy fixator is to ensure the accurate positioning and stable posture of the patient during radiotherapy to obtain the best radiotherapy effect. At present, there are related adaptive pelvic radiotherapy fixators on the market, such as Civco Medical Solutions' Thermoplastic Qfix System and Orfit's bed-based pelvic radiotherapy fixator. These products have good adaptability and comfort, and are easy to operate.

[0003] After searching, in the prior art, Chinese patent application number: CN202122818038.8 discloses a prone position fixation device for pelvic radiotherapy, the utility model: comprises a bearing plate, the inner wall of the bearing plate is provided with an adjustment hole, a fixing belt is fixedly installed in the middle of the bearing plate, a fixing clip is fixedly installed on the outer wall of the fixing belt on the right side, and a protrusion is fixedly installed on the outer wall of the fixing belt. In the prone position fixation device for pelvic radiotherapy, the patient lies on the bearing plate with his legs spread outward in an "eight" shape, and the medical staff covers the patient's body with a thermoplastic film, and then adjusts the position of the leg separator and the adjustment hole according to the size of the patient's body. When adjusted to a suitable position, the thermoplastic film is fixed to the left and right fixing belts and the leg separator by fixing the plastic strip to fix the patient's device, thereby not only achieving the fixation of the patient, but also ensuring the good repeatability of the patient's pelvic position, greatly improving the treatment effect, and reducing the side effects of radiotherapy.

[0004] However, in current clinical work, the most commonly used pelvic radiotherapy fixators are Orfit frames, vacuum bags, and foam glue.

[0005] (1) The size of the Orfit frame is fixed and cannot be adjusted according to the height of each person;

[0006] (2) If the vacuum bag is not stored properly, it is easy to leak, requiring repositioning and remaking of the vacuum bag, which delays the continuity of the patient's treatment and increases the repetitive workload of doctors and therapists;

[0007] (3) In addition, the above three types of fixators are large in size and cannot be folded, which is not only inconvenient for patients to carry back and forth during treatment, but also greatly increases the space cost of storing fixators in the hospital.

[0008] (4) When using the above three types of fixators for fixation, the therapist is required to manually draw lines on the fixation device for marking. This manual marking not only has manual errors, but is also easily affected by the air temperature and humidity in the storage room, resulting in blurred lines and affecting the accuracy of treatment.

At the same time, the limiting sliders 18 arranged on both sides of the first bracket 19 slide in the limiting slide grooves arranged inside the placement groove 17, so that the first bracket 19 can be fixed in a limited position. After the limited position is fixed, the fixing frame 4 is rotated so that the second bracket 21 thereon is flipped and folded on the inner side of the first bracket 19 through the rotating rod 20, so that the fixing frame 4 is attached to the side of the third fixing seat 3, so as to reduce the volume of the pelvic fixator and facilitate transportation.

[0044] A placement pad 16 for placing the patient's head is fixedly installed at the center of the other end of the top of the fixing frame 4, and rubber clamping pads 15 for fixing the head are arranged at both ends of the placement pad 16. By setting the rubber clamping pads 15, it is convenient to play a role of limiting protection for the side of the patient's head; and the two ends of the bottom of the rubber clamping pad 15 are fixedly connected with a clamping block 14, and the clamping block 14 is clamped in the corresponding clamping slot 13 opened on the top of the fixing frame 4, and the clamping block 14 is adapted to the clamping slot 13. The utility model is provided by using the clamping slot 13 and the clamping block 14 and other components in coordination, so as to facilitate the disassembly and replacement of the rubber clamping pad 15.

[0045] During specific use, when the length of the pelvic radiotherapy fixator needs to be adjusted, the first fixing seat 1 is grasped by hand and pulled to one end, so that the first telescopic rod 5 on it and the second telescopic rod 6 on the third fixing seat 3 are slowly pulled out. At the same time, the moving block 12 arranged on the bottom of the first fixing seat 1 and the second fixing seat 2 slides in the moving groove arranged on the external lying table, thereby improving the stability during the telescopic adjustment. The reverse operation can reset it for easy storage.

[0046] When the fixing frame 4 needs to be flipped and folded, the fixing frame 4 is taken by hand and moved to the right end, so that the fixing frame 4 drives the first bracket 19 and the second bracket 21 thereon to be pulled out of the placement groove 17. At the same time, the limiting sliders 18 arranged on both sides of the first bracket 19 slide in the limiting slide grooves arranged inside the placement groove 17, so that the first bracket 19 can be fixed in a limited position. After the limited position is fixed, the fixing frame 4 is rotated so that the second bracket 21 thereon is flipped and folded on the inner side of the first bracket 19 through the rotating rod 20, so that the fixing frame 4 is attached to the side of the third fixing seat 3, so as to reduce the volume of the pelvic fixer and facilitate carrying.
