Description

一种放射治疗设备Radiotherapy equipment 技术领域Technical field
本发明涉及医疗器械技术领域，尤其涉及一种放射治疗设备。The present invention relates to the field of medical device technology, and in particular, to a radiation therapy device.
背景技术Background technique
肿瘤是一种常见的多发病，而放射治疗是一种常见的肿瘤治疗手段。Tumor is a common and frequently-occurring disease, and radiation therapy is a common treatment for cancer.
现有放射治疗设备，如图1所示，包括机架1、悬臂2(C形臂)、治疗头3以及治疗床4，其中，治疗头3能够发出放射束，机架1固定设置于地面上，悬臂2与机架1连接，且悬臂2可带动治疗头3沿旋转轴线11圆周旋转。放射束的中心与旋转轴线11的交点为“等中心12”，患者位于治疗床4上，将肿瘤与等中心12位置对应，以实现对肿瘤的放射治疗。The existing radiotherapy apparatus, as shown in FIG. 1, includes a frame 1, a cantilever 2 (C-arm), a treatment head 3, and a treatment bed 4, wherein the treatment head 3 is capable of emitting a radiation beam, and the frame 1 is fixedly disposed on the ground. Upper, the cantilever 2 is connected to the frame 1, and the cantilever 2 can drive the treatment head 3 to rotate circumferentially along the axis of rotation 11. The intersection of the center of the radiation beam and the axis of rotation 11 is "isocenter 12", the patient is located on the treatment bed 4, and the tumor is positioned corresponding to the isocenter 12 to effect radiation therapy of the tumor.
如图2所示，由于治疗头3的重量以及悬臂悬伸的尺寸过大，导致放射治疗设备在使用过程中出现治疗头不同程度的下垂，从而造成等中心12的非故意偏移，如图2所示，偏移距离为d。尤其在治疗头3圆周旋转的情况下，如图2所示，如虚线所示，当治疗头3旋转至底部时，等中心向另一方向偏移，即误差精度成倍降低。而等中心发生偏移，治疗头发出的放射束不仅没有照射到肿瘤，起不到治疗效果，而且治疗头发出的放射束照射人体正常组织或器官，产生额外辐射，还有可能引发二次肿瘤。As shown in FIG. 2, due to the weight of the treatment head 3 and the oversized cantilever overhang, the radiation treatment device has different degrees of sagging of the treatment head during use, thereby causing unintentional deviation of the isocenter 12, as shown in the figure. As shown in 2, the offset distance is d. Particularly in the case where the treatment head 3 is rotated circumferentially, as shown in FIG. 2, when the treatment head 3 is rotated to the bottom as shown by the broken line, the isocenter is shifted in the other direction, that is, the error precision is doubled. When the isocenter shifts, the radiation beam from the treatment of the hair not only does not irradiate the tumor, but also does not provide a therapeutic effect, and the radiation beam from the treatment of the hair irradiates the normal tissues or organs of the human body to generate additional radiation, and may cause secondary tumors. .
