Description

一种放射聚焦刀
交叉引用
本申请引用于2016年11月24日提交的专利名称为“一种放射聚焦刀”的第2016212652551号中国专利申请，其通过引用被全部并入本申请。
技术领域
本发明涉及一种医疗设备，具体涉及一种将钴-60等单个同位素密封放射源准直后，由机器人或机械臂操控，在体内要求的部位聚焦，从而对身体内肿瘤或其它病变施行立体定向放射治疗的放射聚焦刀。
背景技术
已知的立体定向放射治疗技术是利用放射线治疗肿瘤的一种局部治疗方法。放射线包括放射性同位素产生的α、β、γ射线和各类x射线治疗机或加速器产生的x射线、电子线、质子束及其他粒子束等。大约对70％的癌症患者在治疗癌症的过程中需要用放射治疗，放射治疗在肿瘤治疗中的作用和地位日益突出，已成为治疗恶性肿瘤的主要手段之一。立体定向放射治疗发展至今，比较成熟且被广泛使用的有伽玛刀、X-刀和射波刀等。伽玛刀、X-刀的聚焦原理是将范围大的射线束经准直器(准直器形状为中央带孔的柱状金属块)变为较细的射线束射出，然后从多个方向投射，会聚于一处。如伽玛刀由201个钴-60源和201个准直器组成201条射线束射向同一点。
CT检查、X线透视同样对人伤害不大，放射治疗的关键是怎样在不伤害正常组织的情况下杀灭病变组织，这是放射外科目前的一大技术瓶颈，也是目前亟待解决的问题。另外上述两种器械体积非常庞大、笨重。
发明内容
为了克服背景技术中的不足，本发明公开一种放射聚焦刀，通过单一的放射源围绕病变部位做任意方向的旋转放射，来杀死肿瘤，顶替现有笨重的设备。
为实现上述发明目的，本发明采用如下技术方案：
一种放射聚焦刀，包括辐射系统，所述辐射系统固定在机器人或机械臂上，机器人或机械臂控制辐射系统围绕病变部位做旋转放射。
所述旋转放射的轨迹是球形或类球形
所述辐射系统内部设有源容器，源容器内设有钴-“60”，源容器上设有一开口，滑块插在开口中，所述滑块向一侧滑动后形成放射孔，放射孔处对应设有准直器。
所述源容器上设置的开口为角形凹陷，所述钴-“60”设置在角形凹陷的角处，也就是源容器的中心位置，由角形滑块扣在所述角形凹陷上，在角形滑块的上下面上分别设有凸起条，角形凹陷的上、下壁对应角形滑块凸起条处分别设有滑槽，通过凸起条与滑槽的滑动配合获取滑块的移动。
所述钴-“60”放射源能够用镭-226源、铯-137源、铱-192源、碘-125，金-198源、锶-90同位素β源、锎-252中子源、X线治疗机、加速器产生的X线、电子束、高LET射线中的任意一种替换。
所述源容器为球形结构或多角形结构或柱形结构。
所述球形结构包括椭球形结构或棒状具有椭球形外缘面的结构。
所述多角形结构包括棒状具有多角形结构外缘面的结构。
由于采用如上所述的技术方案，本发明具有如下有益效果：
1、该设备将伽玛刀等庞大的辐射系统改为一个单一的放射源，轻便、灵活，使辐照设备可以随意操控。如按照球形或类球形，围绕病人以设计好的速度做扫描转动，虽然各个部位放射线都在转动中瞬间掠过，但球心焦点处始终被照射。焦点处可以得到以前无法达到的坏死剂量，即任何有生命的组织在此处均被杀灭。真正实现彻底杀灭靶区组织而周围组织不受损伤，这一放射外科追求的终极目标。
2、与目前的立体定向放射治疗设备(伽玛刀、X-刀和射波刀)相比，造价低廉，设备简单。
3.环保性能好。放射源的强度(也称活度)低，比起伽玛刀的总活度六千居里可以成百倍地下降。
4、辐射系统体积小，可以更好地与现有的影像定位及各种追踪系统匹配，不易遮挡追踪设备的扫描，以至于形成死角。
5.由于放射源强度低，放射线的防护更容易，不仅设备便宜，治疗室 的建筑费用也大幅缩减。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
结合附图1～4所述的放射聚焦刀，包括源容器1、钴-“60”2和滑块3，所述源容器1为球形结构或多角形结构或柱形结构，钴-“60”2设置在源容器1中部，在源容器3上设有一开口；所述源容器1上设置的开口为角形凹陷，所述钴-“60”2设置在角形凹陷的角处，也就是源容器1的中心位置，由角形滑块3扣在所述角形凹陷上，在角形滑块3的上下面上分别设有凸起条15，角形凹陷的上、下壁对应角形滑块凸起条15处分别设有滑槽14，滑块3插在角形凹陷“开口”中，通过凸起条15与滑槽14的滑动配合获取滑块3的移动；或在角形滑块的上下面上分别设有滑槽14，角形凹陷的上、下壁对应角形滑块3滑槽14处分别设有凸起条15，通过滑槽14与凸起条15的滑动配合获取滑块的移动，所述滑块3向一侧滑动后，滑块3与角形凹陷的间隙形成放射孔8，在对应放射孔8处设有一个准直器4，所述准直器4为管状结构，管状结构的准直器4为多个以备替换，准直器4包括小孔准直器5、中孔准直器6和大孔准直器7，由源容 器1、钴-“60”2、滑块3和准直器4形成辐射系统9，在源容器1上设有夹持端，所述夹持端连接辐射系统9的夹具；所述辐射系统为一个单一的放射源，辐射系统9由机器人或机械臂16操控，所述辐射系统9围绕病变部位12焦点连续旋转放射，如按照球形或类球形轨迹，围绕病人以设计好的速度做扫描转动，虽然各个部位放射线都在转动中瞬间掠过，但球心焦点处始终被照射。焦点处可以得到以前无法达到的坏死剂量，即任何有生命的组织在此处均被杀灭。真正实现彻底杀灭靶区组织而周围组织不受损伤，这一放射外科追求的终极目标。
其中所述钴-“60”2或替换为镭-226源、铯-137源、钴-“60”源、铱-192源、碘-125，金-198源、锶-90同位素β源、锎-252中子源、X线治疗机和加速器产生的X线、电子束或高LET射线的任意一种。
实施本发明所述的放射聚焦刀，结合附图1～5，本发明通过源容器1、钴-“60”2、滑块3和准直器4组合形成全新结构的辐射系统9，完全脱离了现有的多个辐射系统形成的笨重结构，本发明采用的结构为单一辐射系统9的放射性同位素源，如一个单一钴-60源，置于一个源容器1内，源容器4外观形状可以变化，源容器1前方加用一个准直器4，所述准直器4可根据病患11的病变部位12尺寸选取不同孔径的准直器4，所述准直器4的内孔直径每增加一公分为一个准直器；其中每增加的尺寸根据实际需要而定，所述一公分的增加量仅仅是一个例举；放射外科的准直器4，都是由防护材料制成的中央带有圆孔的圆柱体准直器4。为便于更换准直器4，上述辐射系统可以外加坚硬材料，前段制成与准直器形状相同的圆柱状的壳体，然后与机器人或机械臂、计算机工作站、影像定位及各种追踪系统等现有技术相结合，最大限度地对肿瘤等病变进行杀灭。
治疗之前，先使用高分辨率CT扫描患者并通过成像确定肿瘤的大小、形状和位置；之后，这些扫描的影像数据以数字形式传送至计算机工作站，在这里开始制定治疗计划；如肿瘤体积小可设置一个焦点覆盖肿瘤，如肿瘤体积较大且不规则，为方便起见，可将肿瘤分割成一定体积的多块，设置多个焦点逐一进行损毁；完整的治疗计划可使肿瘤完全被靶区覆盖，同时尽量减少对周边健康组织的覆盖。放射源运行的轨迹是沿球形的纬线转动，每转动一圈所间隔的距离，及转动的速度根据需要照射的时间而定。 治疗计划制定好后，便可以为患者进行治疗。病人到达治疗室后，舒适地躺在治疗床13上，之后计算机控制的聚焦刀机器人将会缓慢地移动至患者需要治疗的部位，操作辐射系统9用射线10照射肿瘤。
具体实施中，源容器和准直器由防护材料制成，常用的防护材料有铅，也可用钨或铀的合金以及其它材料。
优选地，在本发明的一个实施例中，只选取了一个钴-“60”源，其由机器人或机械臂操控沿球形轨迹运行，如循球形的纬线每隔1厘米转一圈，将球形运转一遍，以便在整个过程中，放射线始终指向球心。这样，既不损伤周围组织，球心的放射剂量又可被有效放大，可以一次将肿瘤杀死。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
