Description

Technical Field

[0001] The utility model relates to the technical field of radiotherapy positioning devices, in particular to a radiotherapy auxiliary positioning device. Background Technique

[0002] During the radiotherapy process of specific cancers such as vulvar cancer, the stability of the patient's body position is crucial for ensuring the treatment accuracy and effect. Especially in the treatment of vulvar cancer, due to the particularity of its treatment position, it is usually required that the patient's legs maintain a relatively fixed position. In traditional treatment methods, a thermoplastic film is usually used to fix the patient's legs to ensure stability during the treatment process.

[0003] However, in practical applications, the traditional thermoplastic film fixing method has obvious limitations. First of all, although the thermoplastic film has a certain shaping and fixing ability, its fixing effect is not stable. Especially during a long-term treatment process, the position of the patient's sole may shift, which may then cause the legs to shift. This shift may not only lead to a decrease in treatment accuracy but also cause the thermoplastic film to not fit accurately during subsequent treatment, thereby affecting the treatment effect. Therefore, in order to solve the above problems, this device designs a radiotherapy auxiliary positioning device. Content of the Utility Model

[0029] The fixing component includes a fixing strap 21 fixedly installed on the side wall of the foot bracket 20. A fixing frame 22 is fixedly installed on the side wall of the foot bracket 20 away from the fixing strap 21. The free end of the fixing strap 21 away from the foot bracket 20 movably penetrates through the inside of the fixing frame 22, and the free end of the foot bracket 20 is fixed by an adhesive component. Among them, when the patient's foot is placed on the foot bracket 20, the foot can be fixed in the foot bracket 20 through the fixing strap 21, and the cooperation mode of the fixing strap 21 and the fixing frame 22 is similar to the fixing mode on shoes.

[0030] The adhesive component includes a male magic tape 23 and a female magic tape 24 fixedly installed on the outer wall of the fixing strap 21, and the male magic tape 23 and the female magic tape 24 are adhered to each other.

[0031] A plurality of notches 11 are respectively formed on the opposite side edges of the bed board 10. A bidirectional lead screw 31 is rotatably connected inside the mounting plate 30. One end of the bidirectional lead screw 31 movably penetrates through the side wall of the mounting plate 30 and extends outside the mounting plate 30. A turning handle 33 is fixedly installed at the end of the bidirectional lead screw 31 located outside the mounting plate 30. Threaded sliders 34 are respectively threadedly connected to the threads on both sides of different directions on the outer wall of the bidirectional lead screw 31. The side walls of the threaded sliders 34 are slidably connected to the inner wall of the mounting plate 30. A clamping block 32 (the shape and size of the clamping block 32 are adapted to the notch 11 and is semi-circular) is fixedly installed on the bottom wall of the threaded slider 34. The two clamping blocks 32 are respectively clamped and fixed inside the two notches 11. Among them, when installing the mounting plate 30 on the bed board 10, the turning handle 33 can be rotated clockwise. The turning handle 33 drives the bidirectional lead screw 31 to rotate. The threads on the outer wall of the bidirectional lead screw 31 are engaged with the threads on the inner walls of the two threaded sliders 34, so as to drive the two threaded sliders 34 to move towards each other until the two clamping blocks 32 are clamped and tightened inside the two notches 11, and then the fixing of the mounting plate 30 on the bed board 10 can be completed.

[0032] The adjusting mechanism includes two moving plates 40. The moving plates 40 are movably installed on the side wall of the mounting plate 30, and the foot bracket 20 is movably installed on the moving plates 40.

[0033] The side wall of the mounting plate 30 is provided with a first sliding groove 42. The end wall of the moving plate 40 is fixedly connected with a first moving block 41. The outer wall of the first moving block 41 is slidably connected to the inner wall of the first sliding groove 42. A first threaded hole 43 is provided on the top wall of the first moving block 41. A plurality of through holes 44 are provided on the top wall of the mounting plate 30. The inner parts of two of the through holes 44 are respectively provided with a first screw rod 45. The bottom end of the first screw rod 45 is threadedly connected to the inside of the first threaded hole 43. Among them, the position of the moving plate 40 on the mounting plate 30 can be adjusted. When adjusting the position of the moving plate 40, the first screw rod 45 can be rotated counterclockwise to remove the first screw rod 45 from the first threaded hole 43, releasing the fixation of the first screw rod 45 on the first threaded hole 43, and then moving the first moving block 41 to adjust the position of the first moving block 41. When the first moving block 41 is adjusted to a suitable position, the first screw rod 45 is reinstalled into the first threaded hole 43 to fix the moving plate 40.

[0034] A second moving block 51 is fixedly installed on the bottom wall of the foot bracket 20. A second threaded hole 52 is provided on the side wall of the second moving block 51. A second sliding groove 53 is provided on the side wall of the moving plate 40. The outer wall of the second moving block 51 is slidably connected to the inner wall of the second sliding groove 53. A through hole 54 is provided on the side wall of the second sliding groove 53. A second screw rod 55 is movably installed inside the second threaded hole 52. The end of the second screw rod 55 penetrates through the second threaded hole 52 and is threadedly connected to the inside of the through hole 54. Among them, the position of the foot bracket 20 on the mounting plate 30 can be adjusted. When adjusting, the second screw rod 55 can be rotated counterclockwise to remove the second screw rod 55 from the through hole 54, releasing the fixation of the second screw rod 55 on the second moving block 51, and then moving the position of the second moving block 51 in the second sliding groove 53 to adjust the position of the foot bracket 20. After adjusting to a suitable position, the second moving block 51 is locked and fixed again through the second screw rod 55.

[0035] In this embodiment, the working principle of the device is as follows: When using this device to fix the patient's feet, the patient can lie on the bed board 10, and then adjust the position of the foot bracket 20 according to the positions of the two soles of the feet after the patient lies on the bed, so that the patient's soles can step on the foot bracket 20.

[0036] Then assist the patient to step on the two soles on the foot bracket 20, and use the fixing belt 21 to bind and fix the feet on the foot bracket 20. At this time, the phenomenon that the patient's soles shift during radiotherapy can be avoided, and further the phenomenon that the thermoplastic film cannot be buckled during subsequent treatment can be avoided, indirectly improving the treatment effect.
