[0002] A radiation localization device is a medical device used to precisely locate and target a tumor during radiation therapy for oncology. It uses a variety of technologies to ensure that the treatment dose is delivered accurately and focused to the tumor area while minimizing damage to surrounding healthy tissue.

[0003] The traditional positioning device softens the heat shrink film and applies it to the treatment area of ​​the human body, and forms a fixed cover after hardening. A fixing plate is installed around the heat shrink film, and the heat shrink film is fixed by connecting the fixing plate to the bed, thereby achieving its fixation effect on the human body. However, this may result in insufficient fit and comfort for patients with different body shapes and affected areas.

DETAILED DESCRIPTION

[0036] The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention can be implemented in various forms, so the present invention is not limited to the embodiments described below. In addition, in order to more clearly describe the present invention, components that are not connected with the invention will be omitted from the drawings.

[0037] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0038] Please refer to Figure 1 - Figure 3 As shown, this embodiment introduces a specific structure of a radiotherapy positioning device for tumor radiotherapy, including a detection bed 1, a fixing component 2, a mounting component 3, and an air-drying component 4. The detection bed 1, the fixing component 2, the mounting component 3, and the air-drying component 4 are all arranged on the upper side of the detection bed 1. The fixing component 2 is used to clamp the heat shrink film, the mounting component 3 is used to fix the fixing component 2 on the upper side of the detection bed 1, and the air-drying component 4 is used to air-dry the heat shrink film.

[0039] Each set of fixing components 2 includes two upper clamping plates 201 and two lower clamping plates 202. The upper clamping plates 201 and the lower clamping plates 202 are provided with sliding grooves 203 inside. The sliding grooves 203 are slidably connected with sliding bars 204 inside. A hinge 205 is fixedly connected between the opposite ends of two adjacent sliding bars 204.

[0040] When clamping the heat shrink film, the heat shrink film is cut into the required size and shape according to the position of the patient's surgical area, and then the edge of the heat shrink film is placed between the upper and lower clamps 201 and the lower clamp 202. The heat shrink film is clamped and fixed by the upper and lower clamps 201 and the lower clamp 202. Since the shapes of the heat shrink films are different, when the edges of the heat shrink films are long, the distance between the adjacent upper clamps 201 or the lower clamps 202 can be lengthened to extend the length of each group of fixing components 2. In addition, the angles between the adjacent sliding bars 204 can be adjusted by the hinges 205, and then the angles between the adjacent upper clamps 201 or the lower clamps 202 can be adjusted, so as to clamp the edges of the heat shrink film well and ensure that the surgical area is effectively covered to ensure accurate positioning.

[0041] Please refer to Figure 1 - Fig.10 As shown, the mounting assembly 3 includes a fixing hole 301, which is provided on the side of the upper clamping plate 201 and the lower clamping plate 202 away from the sliding bar 204, and a fixing hole 302 is provided in the middle of the hinge 205. The middle of the fixing hole 301 and the fixing hole 302 are penetrated by an outer rod 303, and the inner sliding rod 304 is slidably connected to the inner sliding rod 304. The middle of the inner sliding rod 304 is fixedly connected to a protrusion 305, and a slot 306 is provided in the middle of the protrusion 305. A plurality of placement grooves 307 are provided in an annular manner in the middle of the outer rod 303, and the interiors of the plurality of placement grooves 307 are all slidably connected to limit ball 306. 08. A spring 1 309 is arranged inside the outer rod 303. A limit ring 1 310 is fixedly connected to the lower inner side of the outer rod 303. The spring 1 309 is arranged between the opposite ends of the convex block 305 and the limit ring 1 310. The spring 1 309 is arranged outside the lower side of the inner slide bar 304. The bottom end of the inner slide bar 304 passes through the middle part of the limit ring 1 310 and the bottom end of the outer rod 303. The top of the outer rod 303 is fixedly connected to the limit ring 2 311. A plurality of card slots 2 312 are provided at the top of the detection bed 1. A card groove 313 is provided inside the card slots 2 312. The outer rod 303 is arranged inside the card slots 2 312.

[0042] When the upper clamping plate 201 and the lower clamping plate 202 need to be fixed on the top of the detection bed 1, the fixing assembly 2 is first placed on the top of the detection bed 1, and the fixing hole 1 301 and the fixing hole 2 302 are aligned with the corresponding position of the card slot 2 312, and then the lower side of the outer rod 303 is passed through the upper clamping plate 201, the upper end fixing hole 1 301 of the lower clamping plate 202 or the fixing hole 2 302 in the middle of the hinge 205 so that the bottom of the outer rod 303 enters the inside of the card slot 2 312. When the limiting ball 308 in the middle of the outer rod 303 contacts the edges of the fixing hole 1 301 and the fixing hole 2 302, Because the portion of the limiting ball 308 protruding from the outer wall of the outer rod 303 blocks the outer rod 303 from moving downward, the limiting ball 308 is also blocked by the outer wall of the protrusion 305 and cannot gather inward, so the outer rod 303 cannot continue to move downward. Therefore, the inner slide bar 304 is pressed, and the inner slide bar 304 moves downward to drive the slot 1 306 to move downward, and at the same time drives the protrusion 305 to move downward and then compress the spring 1 309 with the limiting ring 1 310 to contract. When the slot 1 306 and the limiting ball 308 are in the same position, the limiting ball 308 is at the edge of the fixing hole 1 301 and the fixing hole 2 302. When the locking nut 306 is fully reset, a portion of the locking nut 308 is released. The first and second clamping plates 301 and 302 are respectively located in the upper and lower parts of the test bed 1 and the lower and second clamping plates 302. The first and second clamping plates 301 and 302 are respectively located in the upper and lower parts of the test bed 1 and the lower and second clamping plates ...

[0043] Please refer to Figure 1 - Fig.12As shown, the air-drying component 4 includes an air pump 401, which is fixedly connected to the upper side of the detection bed 1, and the output end of the air pump 401 is fixedly connected to a connecting pipe 402, an airway 1 403 is provided inside the top of the detection bed 1, and the connecting pipe 402 is connected to the airway 1 403, and two air holes 1 404 are provided between the airway 1 403 and the plurality of second card slots 312, and a spring 2 405 is provided inside the second card slot 312, and an air-blocking block 406 is slidably connected inside the second card slot 312, The air-blocking block 406 is arranged at the top of the second spring 405, the middle of the air-blocking block 406 is provided with a second air hole 407, the middle of the inner slide bar 304 is provided with a second air passage 408, the upper side of the inner slide bar 304 is provided with a third air hole 409, the upper side of the outer sleeve rod 303 is provided with a fourth air hole 410, the interior of the upper splint 201 and the lower splint 202 are provided with a third air passage 411, the opposite ends of the adjacent upper splint 201 and the lower splint 202 are provided with exhaust grooves 412, and the upper splint 201 and the lower splint 202 are provided with exhaust grooves 413. The top is provided with an exhaust hole 413, the airway 1 403 is connected with the air hole 1 404, the airway 2 408, the air hole 3 409, and the air hole 410 are connected in sequence, the airway 3 411 is connected with the exhaust groove 412, and the airway 3 411 is connected with the exhaust hole 413. The inner lower side of the outer sleeve rod 303 is fixedly connected with two sliders 1 414 set opposite to each other, and the upper outer side of the air-blocking block 406 is provided with two slideways 1 415 set opposite to each other. The two slideways 1 415 are designed to spiral downward, and the two slideways 1 415 are designed to spiral downward. The travel angle of the two end points of the slideway 1 415 when viewed from the top is 90°. Two sliders 2 416 are fixedly connected to the middle of the outer side of the air-blocking block 406. Two slideways 2 417 are opened on the lower inner side of the slot 2 312 and are relatively set. The two slideways 2 417 are designed to be spiral downward. The travel angle of the two end points of the two slideways 2 417 when viewed from the top is 90°. The two sliders 2 416 move inside the adjacent slideways 2 417 respectively. A proximity switch 418 is fixedly connected to the lower end of one side of the slideway 2 417.

[0044] The heat shrink film needs to be softened by hot water. When the softened heat shrink film with hot water is applied to the human body, it needs to be quickly air-dried and cooled to solidify. When the upper splint 201 and the lower splint 202 are fixed, the outer rod 303 moves downward in the second card slot 312, and the protruding part of the upper side of the air-tight block 406 enters the inner part of the outer rod 303, and the two sliders 414 on the lower side of the inner part of the outer rod 303 respectively enter the inner parts of the two slideways 415. Under the continuous downward pressure of the outer rod 303, the two sliders 414 move in the inner parts of the two slideways 415 respectively. Since the two slideways 415 are designed to spiral downward, the two sliders 414 move in the two slideways 415 respectively. When the slider 1 414 moves inside, it is blocked by the inner wall of the slideway 1 415. On the one hand, the slider 1 414 pushes the air-blocking block 406 to move downward. On the other hand, under the constraint of the slideway 1 415 and the constraint of the slideway 2 417 on the slider 2 416, the slider 1 414 and the slider 2 416 slide inside the adjacent slideway 1 415 and the slideway 2 417 respectively. However, since the slideway position of the slideway 2 417 is in a fixed position, the slideway 2 417 constrains the slider 2 416 to rotate along the track direction of the slideway 2 417 while moving inside it, thereby driving the air-blocking block 406 to rotate 90°. When the installation component 3 fixes the upper clamping plate 201 and the lower clamping plate 202 to the detection When the bed 1 is at the top, the air hole 2 407 is just connected with the air hole 1 404 through the downward movement and rotation of the air-blocking block 406. The air-blocking block 406 compresses the spring 2 405 while moving downward. Moreover, the air hole 410 is also connected with the airway 3 411 inside the upper clamping plate 201 and the lower clamping plate 202 outside the airway 1 403. In addition, when the slide block 2 416 moves to the bottom of the adjacent slideway 2 417, it will contact the proximity switch 418 and then start the air pump 401 through the proximity switch 418. The air pump 401 starts to deliver gas through the connecting pipe 402 into the interior of the airway 1 403. The gas passes through the air hole 1 404, the air hole 2 407, the airway 2 408, the air hole 3 409, and the air hole 410 in turn. 410, air channel three 411, and finally discharged from the exhaust hole 413. The moisture and heat of the heat shrink film clamped between the upper clamping plate 201 and the lower clamping plate 202 can be taken away and discharged from the exhaust hole 413 through the exhaust groove 412. In addition, the gas blown out through the exhaust hole 413 can quickly dry and cool the surrounding thermoplastic film to save time. According to the setting, the air pump 401 automatically shuts down after working for a period of time. Within the time period, it is enough to dry the heat shrink film with gas. In addition, it should be noted that the inner wall of the fixing hole 2 302 is in a closed state, and its inner wall is tightly fitted with the outer wall of the outer rod 303, so it will block the discharge of the gas in the internal air hole 410, thereby avoiding other wastes.

[0045] Please refer to Figure 8 , Fig. 9 and Fig.13As shown, a cutting opening 5 is provided at the bottom of the outer rod 303, a pricking needle 6 is fixedly connected to the bottom end of the inner slide rod 304, a rotating groove 7 is provided on both sides of the pricking needle 6, a rotating shaft 8 is fixedly connected inside the two rotating grooves 7, a barbed hook 9 is rotatably connected to the outside of the two rotating shafts 8, and a torsion spring 10 is sleeved on the outside of the two rotating shafts 8;

[0046] The heat shrink film is clamped by the upper clamping plate 201 and the lower clamping plate 202. When the outer sleeve rod 303 passes through the fixing hole 1 301 and the fixing hole 2 302, it will be blocked by the heat shrink film between the upper clamping plate 201 and the lower clamping plate 202, so that it cannot pass through. Therefore, through the design of the cutting opening 5, when the outer sleeve rod 303 passes through the fixing hole 1 301 and the fixing hole 2 302, the heat shrink film is cut off by the cutting opening 5 through the force of human body pressing. When pressing, the inner slide bar 304 will drive the pricking needle 6 to pierce the heat shrink film first. When the heat shrink film passes through the barbed hook 9, the heat shrink film squeezes the barbed hook 9 to flip, so that the upper side of the barbed hook 9 is collected in the inside of the rotating groove 7. When the heat shrink film completely passes through the barbed hook 9, the torsion spring 10 rebounds and pushes the barbed hook 9 to reset, and then the cut heat shrink film is taken out from the inside of the second card slot 312 through the barbed hook 9, thereby avoiding blockage.

[0047] In summary, it should be noted that, when the heat shrink film is formed, the outer wall of the protrusion 305 is released from the squeezing of the limiting ball 308 by pressing the inner slide rod 304. When the outer rod 303 is moved upward, the inner wall of the second slot 312 will push the limiting ball 308 to shrink to the inside of the first slot 306 again, and then release the movement restriction of the limiting ball 308 on the outer rod 303, so that the outer rod 303 can be moved out of the second slot 312. When the outer rod 303 moves out of the second slot 312, the barbed hook 9 will cut the heat shrink film cut off by the cutting opening 5. The film is taken out from the inside of the second slot 312, and the upper side of the barbed hook 9 is manually squeezed to release the restriction of the barbed hook 9 on the heat shrink film residue, so that the heat shrink film residue can be removed from the needle 6. When the outer outer sleeve rod 303 moves out of the second slot 312, the second spring 405 pushes the air-blocking block 406 to move upward, and the second air hole 407 is reset, and the air hole 1 404 is closed by the outer wall of the air-blocking block 406. At the same time, the air-blocking block 406 moves the slider 2 416 upward and moves away from the proximity switch 418 again, thereby restoring the proximity switch 418 to the state to be triggered for the next use.

[0048] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
