Technical Field
[0001] The utility model relates to a positioning body frame, in particular to a conveniently disassembled chest and abdomen radiotherapy positioning body frame. Background Art
[0002] Radiotherapy is one of the main methods that cannot be ignored in curing malignant tumors, and positioning is the first step in radiotherapy. The results of the CT positioning scan of the patient serve as the basis for delineating the target area and establishing the patient's body coordinate system. During the CT positioning scan, the doctor draws skin marks for the patient and uses the skin marks as positioning reference points during radiotherapy.

DETAILED DESCRIPTION
[0023] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0024] Embodiment 1: The utility model provides a conveniently disassembled chest and abdomen radiotherapy positioning frame, such as Figure 1-4As shown, it includes a fixed platform 1, a first shaft seat 2, a mounting guide groove plate 3, a positioning component, a guide component, a guide rod 31, a push plate 32, a cross bar 33 and a lifting frame 34. The bottom of the fixed platform 1 is hollow, and the middle part of the front side of the fixed platform 1 is provided with a first shaft seat 2, and a mounting guide groove plate 3 for fixing one side of the buckle film is rotatably sleeved on the first shaft seat 2. The fixed platform 1 is provided with a positioning component for clamping and limiting the other side of the buckle film, and a guide component for guiding and limiting the two sides of the buckle film is provided between the mounting guide groove plate 3 and the positioning component. A customized groove is opened on the top of the fixed platform 1 to fix Guide rods 31 are vertically slidably arranged at the four corners of the customized groove of the table, a pushing plate 32 is arranged between the top ends of the four guide rods 31, the shape of the pushing plate 32 is consistent with the customized groove, the pushing plate 32 is located in the customized groove, a cross bar 33 is connected between the bottom ends of two adjacent guide rods 31, the cross bar 33 is located at the lower part of the fixed table 1, and sliding grooves are symmetrically opened at the lower parts of the front and rear side walls of the fixed table 1. A lifting frame 34 is slidably connected in the sliding groove of the fixed table 1, and the lifting frame 34 is connected to the two cross bars 33 at the lower part of the fixed table 1. A U-shaped groove is opened on the left side of the top of the fixed table 1, and an N-shaped frame 35 is rotatably arranged in the U-shaped groove of the fixed table 1.
[0025] Further, such as Figure 2 As shown, the locking assembly includes a fixing frame 6, a locking seat 7 and a first rubber spring 8. The fixing platform 1 is provided with a fixing frame 6. The fixing frame 6 is slidably provided with a locking seat 7 that can slide up and down. The first rubber spring 8 is connected between the locking seat 7 and the fixing frame 6. The first rubber spring 8 is a compression spring, which is used to provide a downward clamping force to the locking seat 7. The locking seat 7 cooperates with the first rubber spring 8 to clamp and limit one side of the buckle film, which is simple to operate and easy to disassemble.
[0026] Further, such as Figure 2 As shown, the guide assembly includes a bracket 4 and a roller 5. The bracket 4 is respectively arranged on the guide groove plate 3 and the fixed frame 6. The roller 5 is rotatably sleeved on the bracket 4. Through the pushing action of the roller 5, the two sides of the buckle membrane can be pressed and guided respectively, which is conducive to the buckle membrane being closely attached to the patient's chest and abdomen, and is convenient for auxiliary radiotherapy of the patient.
[0027] First, the thermoplastic membrane plate is softened, and then the softened thermoplastic membrane plate is placed in the customized groove of the fixed table 1. The patient lies flat on the thermoplastic membrane plate, and then one side of the buckle film can be inserted into the installation guide groove plate 3 so that the buckle film can cover the patient's chest and abdomen. Under the compression of the clamping seat 7 and the first rubber spring 8, the other side of the buckle film can be clamped and limited, and then through the squeezing action of the two rollers 5, the squeezing force can be applied to both sides of the buckle film so that the buckle film can fit tightly with the patient's chest and abdomen. In this way, the two sides of the buckle film can be conveniently fixed to prevent the patient from rotating. Since the hand cannot form a model, the staff can rotate the N-shaped frame 35 to a vertical shape, and the patient holds the N-shaped frame 35 to prevent the hand from squeezing the thermoplastic membrane plate. The patient's contour is sunk into the thermoplastic membrane plate to form the body contour. When the temperature of the thermoplastic membrane plate is reduced and hardened, the thermoplastic membrane plate positioning frame is hardened and formed. At this time, it is only necessary to lift the locking seat 7 upward to separate the locking seat 7 from the buckle film, and then pull out the buckle film to achieve convenient disassembly of the buckle film. The patient leaves the thermoplastic membrane plate frame, and the medical staff lifts the lifting frames 34 on both sides upward, and the cross bar 33 pushes the guide rod 31 to move upward, and the guide rod 31 drives the pushing plate 32 to move upward, which can quickly lift up and take out the hardened thermoplastic membrane plate frame. During radiotherapy, the patient can be perfectly positioned by lying flat on the special thermoplastic membrane plate frame, which is convenient for multiple radiotherapy sessions on the same patient and can achieve the purpose of easy use. When other patients need to use it, the above actions can be repeated to quickly disassemble the radiotherapy positioning frame that suits the patient.
[0028] Embodiment 2: Based on Embodiment 1, Figure 3 As shown, it also includes a second shaft seat 9, a mounting frame 10, a pressure plate 11 and a plastic screw 12. The second shaft seat 9 is arranged in the middle of the fixing frame 6, and the second shaft seat 9 is sleeved with a flippable mounting frame 10. The mounting frame 10 is threaded with a plastic screw 12, and a pressure plate 11 is rotatably arranged at the end of the plastic screw 12, and the pressure plate 11 abuts against the blocking seat 7. By rotating the plastic screw 12 so that the pressure plate 11 presses the blocking seat 7 downward, the blocking seat 7 can be further reinforced, which is beneficial to further reinforce the buckle film.
[0029] Further, such as Figure 3 As shown, it also includes a mounting seat 13, a fixing rod 14 and a second rubber spring 15. The mounting seat 13 is arranged on the fixing frame 6 near the second shaft seat 9. The fixing rod 14 is slidably penetrated on the mounting seat 13. The second rubber spring 15 is sleeved on the fixing rod 14, and one end of the second rubber spring 15 is connected to the mounting seat 13, and the other end is connected to the fixing rod 14. The second rubber spring 15 is also a compression spring, which is used to provide a pressing force to the fixing rod 14.
[0030] In addition, if Figure 1As shown, a fixing block 16 is also included. The fixing block 16 is rotatably arranged on the front side of the fixing platform 1. By rotating the fixing block 16, the guide groove plate 3 can be clamped and limited, which is beneficial to further reinforce the other side of the buckle membrane. The operation is simple and easy to use.
[0031] By twisting the plastic screw 12 so that the pressure plate 11 on it can move downward to squeeze the clamping seat 7, it is beneficial to tighten and reinforce the clamping seat 7, so as to achieve the purpose of reinforcing the buckle film; and by rotating the fixing block 16 so that it can be against the mounting guide groove plate 3, the mounting guide groove plate 3 can be clamped and limited, which is beneficial to further reinforce the buckle film and is easy to use.
