Description

Technical FieldThe utility model relates to a technical field for medical devices and relates specifically to a protection device for tumor radiotherapy.Background TechnologyRadiotherapy for tumors is a local treatment in which tumors are treated with radiation. During radiotherapy, it has always been an important issue in clinical practice how to effectively protect the patient's normal tissue from unnecessary radiation damage and ensure that the tumor site can be accurately irradiated.Some of the existing radiation therapy protection devices are complex in construction, inconvenient to operate and difficult to quickly and accurately set to a suitable protection position. Some of them have poor protective effect and cannot provide flexible and accurate protection depending on the position and shape of the patient's tumor.Therefore, there is an urgent need for a protection device for tumor radiotherapy which can overcome the above-mentioned deficiencies and improve the protection effect and comfort of radiotherapy.Content of the Utility ModelThe utility model discloses a technical object to be solved by overcoming the deficiencies of the above technology and providing a protection device for tumor radiotherapy.To achieve the object, the technical solution of the invention is a protection device for tumor radiotherapy, which includes two symmetrically disposed mounting rails, a slider, a protection main plate, and a protection sub-plate. Each of the mounting rails is provided with a folding seat along its extension direction. The folding seat is provided with a foldable connecting rod. The other end of the connecting rod is provided with a C-shaped clamping head. A threaded rod with a threaded connection is arranged on the C-shaped clamping head. The threaded rod passes through one side of the open end of the C-shaped clamping head. The other end of the threaded rod is provided with a clamping block. Each mounting rail is provided with a slide track No. 1 along its extension direction.Electric telescopic rods are provided at the four corners of the lower surface of the protection main plate, respectively, and a slider is provided at the lower end of each of the electric telescopic rods, respectively. An opening portion is provided which extends longitudinally through the main body of the protection main plate. The protective main plate is provided with a slide track No. 2 on the left and right sides of the opening portion, respectively. In the slideway No. 2, a plurality of uniformly distributed protective sub-plates are provided. Each of the protection sub-plates can respectively perform linear reciprocating motion along the extending direction of the slide track No. 2.Moreover, the connecting rod is firmly connected to the C-shaped clamping head.Moreover, a snap buckle is provided on the side wall of the mounting rail, and the snap buckle is disposed corresponding to the connecting rod.Moreover, the slide track No. 1 is arranged correspondingly with the slider.Moreover, the top surface of each protective sub-plate is provided with a firm grip, respectively.The advantages of the utility model over the prior art are:1) The position and height of the protective main plate can be quickly adjusted by the cooperation of the electric telescopic rod, the slider and the slide track. The medical worker can also easily adjust the position of the protection sub-panel via the handle, which greatly improves the operating efficiency.2) The design of the C-shaped clamping head, threaded rod and clamping block can firmly secure the mounting rail to the radiotherapy bed to ensure stability of the guard during use.3) Multiple guard sub-plates can be flexibly displaced within slideway No. 2 and individually adjusted to the shape and size of the patient's tumor. This achieves precise protection of the normal tissue of the patient and effectively reduces unnecessary radiation damage.Description with DrawingsFIG. 1 is a side view of the tumor radiotherapy protection device of the invention. FIG. 2 is a perspective view 1 of the tumor radiotherapy protection device of the invention. FIG. 3 is a perspective view 2 of the tumor radiotherapy protection device of the invention. FIG. 4 is an enlarged view of part A in FIG. 1 of the tumor radiotherapy protection device of the utility model.As shown in the figure: 1. mounting rail, 2. snap-fit buckle, 3. slideway no. 1, 4. folding seat, 5. connecting rod, 6. C-shaped clamping head, 7. threaded rod, 8. clamping block, 9. slider, 10. electric telescopic rod, 11. protective main plate, 12. opening area, 13. protective subplate, 14. handle, 15. slideway no. 2.The specific embodimentThe utility model discloses a protective device for tumor radiotherapy, which is described in more detail below in connection with the attached drawings.In connection with the accompanying figures, the invention discloses a protective device for tumor radiation therapy, provided that before use two mounting rails 1 have to be installed symmetrically at the appropriate position on the radiation therapy bed. The C-shaped clamping head 6 is clamped onto the support structure of the radiation therapy device, and the clamping block 8 is pressed firmly against the support structure by rotating the threaded rod 7, so that the mounting rail 1 is firmly fixed. If the guard does not need to be used temporarily, the connecting rod 5 can be rotated and the connecting rod 5 is clamped into the snap buckle 2 for storage;In use, depending on the position of the patient's tumor, first, they increase the height of the protection main plate 11, then adjust the position of the protection main plate 11 by sliding the slider 9 so that the opening portion 12 of the protection main plate 11 is aligned with the patient's tumor site, and then re-control the electric telescopic rod 10 to lower the protection main plate 11 to an appropriate position. Finally, the medical personnel push the protective base plate 13 with the handle 14 into the second rail 15 depending on the shape and size of the tumor in order to cover the normal tissue of the patient as far as possible and to achieve a precise protection. During radiation therapy, the positions of the protection main board 11 and the protection sub-board 13 may be adjusted according to actual needs to ensure the protection effect.In use, according to the position of the patient's tumor, first, the height of the protective main plate 11 is adjusted, then the position of the protective main plate 11 is adjusted by moving the slider 9, the opening portion 12 of the protective main plate 11 is aligned with the patient's tumor part, then the electric telescopic rod 10 is again controlled, the protective main plate 11 is dropped to an appropriate position, and finally, the medical worker slides the protective sub plate 13 in the slide No. 2 15 by the handle 14 according to the shape and size of the tumor, and the patient's normal tissue is shielded as much as possible to achieve precise protection.
