Definitions
- the present invention relates to the field of medical devices, and more particularly to a radiotherapy machine. Background technique
- the existing radiotherapy machine consists of a vertical frame, a rotating frame, a treatment head, a collimator and a treatment bed.
- the vertical frame and the rotating frame are connected by bearings, the treatment head and the collimator are mounted on the rotating frame, and the pre-made lead block placed in the collimator has been conformed, and the treatment plan is planned for each shot. Wild needs to make a lead block, a patient usually needs
- An object of the present invention is to provide a radiotherapy apparatus which increases a cariboutic ratio by swinging two treatment heads in the direction of the axis of the drum, respectively.
- the present invention is achieved by a radiotherapy apparatus comprising a base, a roller, two treatment heads and a treatment bed, wherein the roller is mounted on the base, and the treatment head is mounted on the drum
- the utility model is characterized in further comprising two sets of driving devices mounted on the drum and respectively connected with two treatment heads; two sets of gears mounted on the drum and respectively connected with the driving device, a driving device drives the gear to rotate; two sets of curved racks are mounted on the treatment head to respectively mesh with the two sets of gears; when the driving device drives the gears, driven by the gears
- the two treatment heads fixed to the curved rack are respectively swung in the axial direction of the drum.
- the method further includes a curved guide rail mounted on the drum, a center of the curved guide rail coincides with a center of the curved rack and at least one slider mounted on the treatment head, The slider slides on the curved rail.
- the angle of the swing in the direction of the drum axis is 0 to 40 degrees.
- the treatment head 3, 3' is moved on the two rotation surfaces of the space by swinging the treatment head in the direction of the drum axis, thereby improving the coke ratio.
- the combination of dual treatment heads 3, 3 ' can also increase the dose rate at the tumor target.
- FIG. 1 is a schematic structural view of a radiotherapy apparatus according to an embodiment of the present invention
- FIG. 2 is a partial enlarged side view of a radiotherapy apparatus according to an embodiment of the present invention
- 4 is a cross-sectional view of a radiation therapy machine according to an embodiment of the present invention.
- the embodiment of the present invention provides a radiotherapy apparatus.
- the radiotherapy apparatus comprises a base 1, a roller 2, two treatment heads 3, 3' and a treatment bed 4.
- the treatment bed 4 is mounted on the base 1, and the drum 2 is also mounted on the base 1 and connected to the treatment bed 4.
- the treatment heads 3, 3' are mounted on the left and right sides of the drum 2.
- a radioactive source is placed on the treatment head 3, 3', which may be a cobalt source or other radioactive element.
- the radiotherapy apparatus further includes two sets of driving devices 5, 5' mounted on the drum 2 and respectively associated with the treatment heads 3, 3 ' Connected.
- the radiotherapy machine further comprises gears 14, 14', curved racks 13, 13' and curved guides 12, 12' and sliders 15, 15'.
- the gears 14, 14' are mounted on the drum 2 and are respectively connected to the drive means 5, 5', and the curved racks 13, 13' are mounted on the treatment heads 3, 3', the curved guides 12, 12' Mounted on the drum 2, the sliders 15, 15 are mounted on the drum 2 and are slidable on the curved rails 12, 12.
- the gears 14, 14' are respectively engaged with the curved racks 13, 13', and the centers of the curved guides 12, 12' coincide with the centers of the curved racks 13, 13'.
- the curved guides 12, 12' and the sliders 15, 15' function mainly to protect the head 3, 3'.
- the driving device 5, 5' drives the gears 14, 14' to rotate, in the teeth Driven by the wheels 14, 14', the curved racks 13, 13 that mesh with the gears 14, 14' are rotated, thereby making the treatment heads 3, 3' fixedly connected with the curved racks 13, 13'.
- the radiotherapy apparatus further includes weights 8, 8' mounted on the drum 2, symmetrically mounted with the treatment heads 3, 3' for maintaining the balance of the drum 2 during revolution.
- the treatment heads 3, 3' are moved in the direction of the axis of the drum, so that the treatment heads 3, 3' move on the two rotation surfaces of the space, thereby improving the coke ratio.
- the combination of the dual treatment heads 3, 3' can also increase the dose rate at the tumor target.
