Problems solved by technology

[0002] When radiotherapy equipment is performing radiotherapy on patients, it is necessary to control the dose of treatment and the range of radiation exposure in order to achieve the best therapeutic effect and minimize the damage to healthy tissues. Therefore, the latest radiotherapy equipment is located at the radiation head That is, the accelerator is equipped with a grating that can adjust the ray passing area. The grating is provided with a through hole that can be adjusted in size and shape. The coaxial rotation needs to be maintained, so the distance between the radiation head and the lesion is basically fixed, so the distance between the grating and the lesion is also fixed, and the distance to the lesion after the ray passes through the through hole of the grating may be too long to collide with the air and cause Scatter, causing damage to normal tissue

Embodiment 1

[0022] Such as figure 1 As shown, a radiotherapy equipment includes a base 1, a rotating frame 2 connected to the base 1, a radiation head 3, a treatment couch 4 and a control device, and also includes a grating lifting device and a grating for adjusting radiation dose 5. The grating lifting device is provided with an electric control device electrically connected with the control device, a transmission device electrically connected with the electric control device and controlled by it, and a telescopic lifting arm connected with the transmission device 64. The grating 5 is fixedly connected to the lifting arm 6, and the lifting device is fixedly connected to the frame of the rotating machine 2, and can also be fixedly connected to the radiation head 3.

[0023] The transmission device includes a motor 61 and a speed change device connected to the motor shaft, and the lifting arm 64 is connected to the speed change device.

[0024] There are two electric motors 61, four lifti...

Embodiment 2

[0029] Such as figure 2 As shown, the rest are the same as in Embodiment 1, the difference is that the lifting arm includes an X-shaped telescopic frame 65 and a guide column 66, and the free end of the X-shaped telescopic frame 65 is provided with a nut, and the nut is screwed on a lifting arm. On the screw rod, the transmission device includes a motor and a reducer, and the lifting screw rod is in transmission connection with the rotation device. The guide column 66 is freely slidably sleeved in the sleeve fixedly connected to the rotating frame or the radiation head, and the motor drives the lifting screw to rotate, so that the free end of the X-shaped telescopic frame 65 is opened or approached, so that the X-shaped telescopic frame The height of 65 is elongated or contracted, and cooperates with the guide post 66 to adjust the height of the grating.

[0030] In the above-mentioned embodiment, there are one or more electric motors 61, one or more lifting arms, and the tr...

Embodiment 3

[0032] Such as image 3 and Figure 4 As shown, the transmission device is a cylinder, and the cylinder includes two groups, namely a first lifting cylinder 67 and a second lifting cylinder 68, and the lifting arm includes a corresponding first lifting arm 641 and a second lifting arm 642 , the grating lifting device is also provided with a first support plate 671 and a second support plate 681, the first lifting cylinder 67 is fixedly connected to the rotating frame 2 or the radiation head 3, and the first lifting arm 641 The free end of the free end is fixedly connected to the top of the first support plate 671, the second lifting cylinder 68 is fixed to the bottom of the first support plate 671, and the second lifting arm 642 is fixed to the top of the second support plate 681 , the grating 5 is fixedly installed under the second support plate 681 .

[0033] The working principle is that the two-section cylinder system can act simultaneously or separately to achieve a lon...

Abstract

The invention discloses radiotherapy equipment. The radiotherapy equipment comprises a machine base, a rotation machine frame which is in transmission connection with the machine base, a radiation head, a treatment table, a control device, a grating lifting device and a grating for adjusting radiation dose; the grating lifting device is provided with an electric control device which is electrically connected with the control device, a transmission device which is electrically connected with the electric control device, and controlled by the electric control device, and telescopic lifting arms which are in transmission connection with the transmission device; the grating is fixedly connected with the lifting arms; and the lifting device is fixedly connected to the rotation machine frame or the radiation head. The radiotherapy equipment has the advantages that: the grating lifting device can adjust the distance between the grating and lesion, and the phenomenon that rays collide air and are scattered due to the overlong distance between a grating through hole and the lesion, and damage the normal tissues can be avoided.
