Embodiment 1

[0025] Embodiment one: by Figure 1-10 As shown, the present invention comprises positioning bed 1, and described positioning bed 1 is provided with the first bed board 2 that can slide back and forth to adjust, and described first bed board 2 is provided with the second bed board 3 that can slide left and right, described positioning The bottom end of the bed 1 is provided with a rotatable first rotating shaft 4, on which the first rotating shaft 4 is fixedly connected with a first worm 5 and a second worm 6, and a first worm wheel 7 is meshed under the first worm 5, A second worm wheel 8 is meshed below the second worm 6, the first worm 5 and the second worm 6 have the same direction of rotation, and the first worm 7 is fixedly connected with a first double-ended screw 9, so The second worm wheel 8 is fixedly connected with a second double-ended screw 10, the first double-ended screw 9 and the second double-ended screw 10 are rotatably connected with the positioning bed 1, a...

Embodiment 2

[0027] Embodiment two: on the basis of embodiment one, by Figure 6 , Figure 7 , Figure 8 As shown, in order to realize the front and rear sliding adjustment of the first bed board 2, the positioning bed 1 is provided with a rotatable second rotating shaft 20, and the second rotating shaft 20 is slidably provided with a third worm 21, and the first The bed board 2 is fixedly connected with a first positioning block 22, the first positioning block 22 is provided with a rotatable third worm wheel 23, the third worm 21 is connected with the first positioning block 22 in rotation, and the first positioning block 22 is slidingly connected with the second rotating shaft 20, and the third worm wheel 23 is fixedly connected with a rotating arm 24, and the rotating arm 24 is hingedly provided with a positioning rod 25, and the positioning rod 25 is hinged with the positioning bed 1.

[0028] When it is necessary to slide back and forth to adjust the first bed board 2, the second ro...

Embodiment 3

[0029] Embodiment three: on the basis of embodiment one, by Figure 5 As shown, in order to realize the left and right sliding adjustment of the second bed board 3, the bottom end of the second bed board 3 is fixedly connected with a rack 26, and the first bed board 2 is provided with a rotatable third rotating shaft 27. The three rotating shafts 27 are fixedly provided with a gear 28, and the gear 28 and the rack 26 are meshed with each other. The front end of the third rotating shaft 27 is fixedly connected with a worm gear mechanism. Fixed connection.

[0030] The second bed board 3 can move forward and backward together with the first bed board 2. After the front and rear positions are adjusted to an appropriate position, the worm gear mechanism is rotated. Since the worm gear mechanism has self-locking properties, the third rotating shaft 27 is driven to rotate by rotating the worm gear mechanism. , can be locked at any position at any time, and the gear 28 on the third ...

Abstract

A positioning device for the treatment of esophageal cancer, which solves the problem that the positioning bed is not easy to operate to cooperate with the instrument to find the lesion position during the treatment of esophageal cancer; it includes a positioning bed, a first bed board that can be adjusted back and forth, and a second bed board that can be slid left and right. The bottom of the positioning bed is hinged with four support frames, which can be rotated and adjusted at the same time. Each support frame is provided with a vertically sliding support rod, and the bottom end of each support rod is fixedly connected with a roller. The two support rods on the side or the right side can be lifted and lowered at the same time to make the positioning bed offset, and a limb fixing device is arranged on the second bed board, and a locator is arranged on the limb fixing device; the present invention improves positioning accuracy, improves The stability of the body position during radiotherapy and the purpose of more accurate treatment.

Description

technical field [0001] The invention belongs to the field of medical technology, in particular to a positioning device for treating esophageal cancer. Background technique [0002] The commonly used radiotherapy techniques in the radiotherapy of esophageal cancer include: front-to-back, left-right, right-front, left-back, cross-irradiation, three-field irradiation with one front, two back, and conformal radiation therapy (3D-CRT). Post-three field irradiation and 3D-CRT. Only one front, two back and three field photos and 3D-CRT can reach the lethal dose of tumor and at the same time, make the surrounding normal tissues not or less damaged to the greatest extent. In radiation therapy, the level of simulated positioning directly affects the effect of radiation therapy. Contents of the invention [0003] In view of the above technical problems, the purpose of the present invention is to provide a positioning device for esophageal cancer treatment, which solves the problem ...
