Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a patient protection device for tumor radiotherapy. Background Art

[0002] Tumor radiotherapy is a cancer treatment method that uses high-energy rays to kill cancer cells or prevent their growth. This therapy mainly destroys the DNA structure of tumor cells, causing them to lose their ability to proliferate, thereby achieving the purpose of reducing the size of the tumor, controlling the progression of the disease, or completely curing the tumor. Although radiotherapy has a certain therapeutic effect on tumor cells, it will also kill normal cells. Radiotherapy is also harmful to normal human tissues. Therefore, during radiotherapy, in order to protect the patient's healthy tissues from unnecessary radiation doses, it is necessary to ensure that the radiation can accurately irradiate the target tumor area.

[0003] After searching, the patent application number is (202111568581.5), which discloses "a tumor radiotherapy protection component and a tumor radiotherapy protection device", which includes a base plate, side plates are fixed on both sides of the top of the base plate, connecting plates are fixed on both sides of the rotating plate, and four rolling rods are slidably connected between the rotating plate and the rectangular plate. Every two corresponding rolling rods of the four rolling rods are set as a group, and a piece of radiation-proof cloth is rolled together on the outer sides of the two corresponding rolling rods. A fixing mechanism for fixing one end of the rolling rod is provided at one end of the rolling rod close to the rectangular plate, and a rotating mechanism for rotating the rolling rod is provided on the side of the rolling rod close to the rotating plate. By setting the rolling rod and the radiation-proof cloth, adjusting the distance between the two groups of rolling rods and the distance between the rolling rod and the corresponding connecting plate, the length of the two groups of radiation-proof cloth can be adjusted as needed, so that the radiation area at any position and any size can be adjusted, thereby improving the accuracy of the shielding protection area.

[0004] However, the above device has the following problems: during radiotherapy, the patient needs to repeat the same body position each time, and medical staff are needed to help the patient place his limbs in the correct posture to avoid irradiation deviation as much as possible and improve accuracy. The current fixation device used in clinical practice is relatively cumbersome, time-consuming and labor-intensive, and its repeatability needs to be improved. For this reason, we propose a tumor radiotherapy patient protection device to solve the above problems. Summary of the invention

[0020] The device solves the problems of the existing radiotherapy fixation device being relatively complicated, easily causing irradiation deviation, reducing accuracy, and having insufficient applicability through the provision of the limiting component 3.

Two sets of first slide grooves 41 are provided on the front and rear sides of the bed board 2, and the first slider 42 is movably connected in the first slide groove 41, and the positioning plate 43 is fixedly connected to the outer side of the first slider 42, and the positioning groove 44 is provided inside the positioning plate 43. Figure 2 and Figure 3 As shown, the structure is used to drive the first slider 42 to move along the first slide groove 41 by pulling the positioning plate 43, so as to facilitate moving the positioning groove 44 on the positioning plate 43 to the tumor position and ensure the radiation irradiation range.

[0022] Furthermore, a shielding assembly 5 is disposed inside the positioning groove 44, and the shielding assembly 5 includes a second slide groove 51, a second slider 52 and a baffle 53. The inner wall of the positioning groove 44 is provided with a second slide groove 51, and two groups of second sliders 52 are movably connected in the second slide groove 51. Two groups of baffles 53 are fixedly connected to the outer sides of the two groups of second sliders 52, and the diameter of the baffle 53 is adapted to the positioning groove 44. Figure 3 As shown, the structure is used to drive the second slider 52 to move along the second slide groove 51 by the baffle 53, and change the position and relative distance between the two baffles 53 according to the size and position of the tumor, so as to ensure that the radiation irradiation range coincides with the size and position of the tumor and reduce the impact on other healthy human tissues.

[0023] Furthermore, an adjustment assembly 6 is provided on the opposite side of the two baffles 53. The adjustment assembly 6 includes a rotating shaft 61, a knob 62, a gear 63, a first connecting plate 64, and a second connecting plate 65. The interior of the positioning plate 43 is rotatably connected to the rotating shaft 61, the right end of the rotating shaft 61 is fixedly connected to the knob 62, the left end of the rotating shaft 61 is fixedly connected to the gear 63, the rear end of the front baffle 53 is fixedly connected to the first connecting plate 64, the front end of the rear baffle 53 is fixedly connected to the second connecting plate 65, and the opposite side of the first connecting plate 64 and the second connecting plate 65 is provided with teeth meshing with the gear 63.

[0024] Furthermore, the inner wall of the positioning plate 43 is provided with two groups of slots 7, which are symmetrically distributed with the positioning slot 44 as the center, and airbags 8 are respectively installed in the two groups of slots 7. Figure 2 As shown, the structure is used to provide certain protection to both sides of the patient inside the positioning plate 43 through the airbag 8 at the slot 7, so as to avoid displacement of the patient's limbs during radiotherapy, thereby affecting the radiotherapy effect.

[0025] Furthermore, a protective layer is provided on the upper surface of the gasket 33, and the protective layer has a certain elasticity. Figure 4 As shown, the structure is used to improve the comfort of the device when the patient lies flat on the pad 33 through the protective layer at the pad 33.

When used for the first time, the pressure is detected by the pressure sensor 34 at the pad 33 below the limbs, and the corresponding electric telescopic rod 32 is controlled to descend to the corresponding scale according to the pressure detected by the pressure sensor 34, so as to form a contour matching the patient, and the patient's limb position is retained as a whole, and the descending position is recorded. The electric telescopic rod 32 that has not descended has a stabilizing effect on the limbs, so that the limbs are sunken in the three-dimensional needle-carved structure, and the patient is quickly fixed, so that the patient can maintain the correct limb placement position according to the record when using it next time. Figure 2 and Figure 3 As shown, the positioning plate 43 is pulled to drive the first slider 42 to move along the first slide groove 41, so as to facilitate moving the positioning groove 44 at the positioning plate 43 to the tumor position, thereby ensuring the radiation irradiation range. Figure 3 and Figure 5 As shown, the rotating knob 62 drives the gear 63 to rotate under the action of the rotating shaft 61, and the teeth at the first connecting plate 64 and the second connecting plate 65 are meshed with the gear 63, thereby driving the baffle 53 to move along the second slide groove 51 through the second slider 52, and changing the position and relative distance between the two baffles 53 according to the size and position of the tumor to ensure that the radiation irradiation range coincides with the size and position of the tumor, thereby reducing the impact on other healthy human tissues. The above is the entire working principle of the present invention.
