[0025] First embodiment

[0026] Please combine with reference to Figure 1 、 Figure 2 、 Figure 3 Among them, Figure 1 A structure schematic view of a first embodiment of the positioning device for target organs in tumor radiotherapy provided by the utility model is shown in the figure; Figure 2 For Figure 1 Another view structure schematic view shown in the figure; Figure 3 For Figure 1 A part enlarged schematic view shown in the figure. The positioning device for target organs in tumor radiotherapy includes: body 1, the bottom of the body 1 is fixedly installed with mounting plate 11;

[0027] Bottom plate 2, the bottom plate 2 is arranged at the bottom of the body 1, the bottom of the bottom plate 2 is fixedly installed with gyro wheel 21 around, the top of the bottom plate 2 is provided with sliding slot 22, one end of the bottom of the bottom plate 2 is fixedly installed with first fixed plate 23, the other end of the bottom of the bottom plate 2 is fixedly installed with second fixed plate 24, one side of the first fixed plate 23 is fixedly installed with drive motor 25, the output end of the drive motor 25 is fixedly installed with screw rod 26, the screw rod 26 is screw connected in the inside of the mounting plate 11;

[0028] The top plate 3 is located on the inner side of the body 1. Two slide rails 31 are fixedly installed on the top of the top plate 3. Slider 32 is slidably connected to the outer side of each slide rail 31. A placement plate 33 is fixedly installed on the top of each slider 32. Telescopic rods 35 are fixedly installed around the bottom of the top plate 3. Electric telescopic rods 36 are fixedly installed at both ends of the bottom of the top plate 3.

[0029] Body 1 is a commonly used tumor radiotherapy device in existing technology.

[0030] The mounting plate 11 is slidably connected to the inner side of the slide groove 22, and the two sides of the mounting plate 11 are respectively attached to the two sides of the inner side of the slide groove 11.

[0031] The mounting plate 11 slides on the inner side of the slide groove 22, which can limit the position of the base plate 2 during use. The roller 21 rolls on the ground, which can make the base plate 2 move left and right, thereby better positioning the position where the patient needs treatment.

[0032] The bottoms of the four telescopic rods 35 and the two electric telescopic rods 36 are all fixedly installed on the top of the base plate 2.

[0033] Handles 34 are fixedly installed on both sides of one end of the placement plate 33.

[0034] When moving the placement plate 33, the user can hold the handle 34 to move it, which makes it convenient for the user to operate.

[0035] The working principle of the target organ positioning device in tumor radiotherapy provided by this utility model is as follows:

[0036] In use, the patient who cannot move independently is moved to one side of the top plate 3 via the hospital bed. Then, the electric telescopic rod 36 is adjusted to retract, which moves the top plate 3 downward until the placement plate 33 is at the same height as the side of the hospital bed. The user then pushes the placement plate 33 to move it to one side of the hospital bed, and then moves the patient onto the placement plate 33. The placement plate 33 is then moved to the top of the top plate 3, and the height of the patient is adjusted by the electric telescopic rod 36. The drive motor 25 is then started, which drives the lead screw 26 to connect threadedly inside the mounting plate 11, thereby moving the patient on the placement plate 33 towards the inner side of the machine body 1 until the patient is moved to a suitable position.

[0037] Compared with related technologies, the target organ positioning device for tumor radiotherapy provided by this utility model has the following beneficial effects:

[0038] The structure, consisting of a top plate 3, a slide rail 31, a slider 32, a placement plate 33, a telescopic rod 35, and an electric telescopic rod 36, works together to allow the placement plate 33 to be adjusted to the same height as the hospital bed and moved to one side of the bed. Then, the patient is simply moved onto the placement plate 33, and the slider 32 slides along the outer side of the slide rail 31, extending the electric telescopic rod 36 to move the patient to the appropriate radiotherapy position. This eliminates the need for medical staff to lift or move the patient, thus reducing their physical exertion.

[0039] Second Embodiment

[0040] Please refer to the following: Figure 4 Based on the target organ positioning device provided in the first embodiment of this application for tumor radiotherapy, the second embodiment of this application proposes another target organ positioning device for tumor radiotherapy. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0041] Specifically, the second embodiment of this application provides a target organ positioning device in tumor radiotherapy, which differs in that the placement plate 33 has an internal threaded connection of a threaded rod 4 at one end.

[0042] The bottom of the threaded rod 4 is rotatably connected to a pad 41, and a rubber pad 42 is fixedly installed on the bottom of the pad 41.

[0043] A rotating plate 43 is fixedly installed on the top of the threaded rod 4.

[0044] The working principle of the target organ positioning device in tumor radiotherapy provided by this utility model is as follows:

[0045] When in use, if it is necessary to limit the placement plate 33, the user can rotate the rotating plate 43, so that the rotating plate 43 drives the threaded rod 4 to make a threaded connection inside the placement plate 33, and then the threaded rod 4 drives the pad 41 and the rubber pad 42 to move downward, so that the rubber pad 42 contacts the top plate 3, and then the placement plate 33 is limited.

[0046] Compared with related technologies, the target organ positioning device for tumor radiotherapy provided by this utility model has the following beneficial effects:

[0047] The threaded rod 4, pad 41, rubber pad 42 and rotating plate 43 work together to form a threaded connection inside the placement plate 33 during use. This causes the pad 41 and rubber pad 42 to move downwards, thus limiting the placement plate 33 and preventing it from moving left or right.

[0048] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
