Description

支撑装置及包含该装置的放射线照射系统 技术领域
本发明涉及医疗设备技术领域，特别是涉及一种支撑装置及包含该装置的放射线照射系统。
背景技术
随着原子科学的发展，例如钴六十、直线加速器、电子射束等放射线治疗已成为癌症治疗的主要手段之一。然而传统光子或电子治疗受到放射线本身物理条件的限制，在杀死肿瘤细胞的同时，也会对射束途径上大量的正常组织造成伤害。另外由于肿瘤细胞对放射线敏感程度的不同，传统放射治疗对于较具抗辐射性的恶性肿瘤的治疗成效往往不佳。
为了减少肿瘤周边正常组织的辐射伤害，化学治疗中的标靶治疗便被应用于放射线治疗中。而针对高抗辐射性的肿瘤细胞，目前也积极发展具有高相对生物效应的辐射源，如质子治疗、重离子治疗和中子捕获治疗等。其中，中子捕获治疗便是结合上述两种概念，如硼中子捕获治疗，借由含硼药物在肿瘤细胞的特异性聚集，配合精准的中子射束照射，提供比传统放射线更好的癌症治疗选择。
放射治疗设备主要用于恶性肿瘤的放射治疗，放射治疗的目的是给靶区最大的照射治疗，从而避免周围正常组织过多接受照射。现有的放射治疗设备中被照射体采用多种体位的治疗方式，而对于被照射体的支撑与定位最主要的部件是治疗床、治疗椅等，并且在治疗过程中都需要移动治疗承载装置。由于被照射体在接受治疗的同时，通常需要被固定在治疗承载装置上，如通过绑带、定制覆膜等的固定结构将被照射体进行束缚和限位，保证被照射体在治疗移动的过程中的安全以及在被治疗过程中接收剂量的精确，治疗承载装置在移动过程中存在碰撞的潜在可能，这种碰撞除了可能会危及被照射体或工作人员的安全，影响治疗，还可能会造成治疗承载装置本身及其附带的固定结构等、甚至放射治疗设备的严重损坏，导致巨大的生命及经济损失。
因此，提出一种支撑装置及包含该装置的放射线照射系统来解决上述问题。
发明内容
为解决上述问题，本发明的一方面提供一种支撑装置，包括载置台以及防撞组件，载置台用于承载被照射体，载置台限定有延伸方向，载置台包括沿延伸方向延伸的支撑表面以及与支撑表面相连的侧面；防撞组件包括设置于侧面的检测件以及突出于侧面设置的防撞件，防撞件用于接触碰撞物并触发检测件进行信号反馈。载置台包括支撑表面、支撑背面以及侧面，作为被照射体的承载平台，其中支撑表面支撑被照射体。防撞组件优选地设置在载置台 的侧面外围，当载置台移动时，防撞组件能够有效地避免载置台及其上的被照射体受到外力的碰撞。优选地，防撞件用于先于载置台承受外力的碰撞，同时起到联动触发检测件的作用。检测件用于根据碰撞件的碰撞动作发出触发信号并进行反馈，使得在移动过程中的载置台能够根据碰撞反馈及时停止运动，进而达到载置台的防碰撞效果。通过防撞件和检测件的设置，有效地保证了载置台以及载置台上被照射体的安全，以及能够避免放射治疗设备的损坏。
本发明一方面提供的支撑装置，通过在载置台侧面周向设置的防撞件以及检测件，极大地提高了在移动过程中的载置台的安全性能。防撞件用于接触碰撞物并触发检测件进行信号反馈，优选地，防撞件设置成先于载置台接触碰撞物，避免了载置台以及被照射体直接受到碰撞。检测件设置成根据碰撞动作接收防撞件触发的碰撞信号，从而控制载置台的进一步运动，避免了载置台与触碰物进一步产生碰撞，从而实现载置台的防碰撞功能。
在其中一个实施例中，载置台还包括与支撑表面相对设置的支撑背面，支撑背面用于与载置台定位装置结合，载置台定位装置用于移动并定位支撑装置。载置台定位装置可以设置在模拟定位室和/或治疗室中，载置台定位装置的活动端与载置台的支撑背面连接，起到移动载置台的作用。在模拟定位室中，结合影像系统、激光定位系统对被照射体的患部位置进行精准标记，同时通过载置台定位装置移动载置台对其进行定位。在治疗室中，结合激光定位系统在模拟定位室中做的标记，通过载置台定位装置对载置台进行配准定位，从而使得被照射体通过载置台移动到理想的照射位置，射束能够对准被照射体的患部位置进行照射治疗。
在其中一个实施例中，载置台定位装置与载置台之间设置有固定装置，固定装置可操作地锁紧和释放载置台定位装置及载置台。固定装置的一部分设置在载置台定位装置上，另一部分设置在载置台上，使得载置台定位装置和载置台之间能够可拆卸地连接。在载置台定位装置移动载置台之前，通过固定装置锁紧载置台定位装置和载置台，使得载置台能够被精准定位。当载置台需要与载置台定位装置分离时，通过释放固定装置解锁载置台定位装置和载置台，使得载置台被移动至其他位置。在模拟定位室中，利用固定装置快速地结合载置台定位装置和载置台，能够对载置台快速定位以获得精准的定位标记，从而节约在治疗室内进行照射治疗前对被照射体模拟定位的工作时间。在治疗室中，利用固定装置快速地结合载置台定位装置和载置台，能够根据根据模拟定位室中获取的定位标记对载置台以及被照射体进行快速精准地配准定位，可以有效地缩短治疗前的准备时间，同时还可以避免治疗室中被照射体以及医护人员非必要的粒子照射剂量。
在其中一个实施例中，载置台上设置有与检测件间隔设置的束缚件，束缚件用于固定被照射体。当束缚件固定被照射体时，束缚件穿过载置台和防撞件之间的区域并实现固定。束缚带与检测件间隔设置，这样既不会对检测件的离散设置造成干扰，同时也不会影响束缚件 固定被照射体。载置台与防撞件之间的区域能够给防撞件受碰撞后留出缓冲区域，使得防撞件受到外力碰撞时不会直接碰撞到载置台，从而可以保证载置台以及被照射体的安全。此外，载置台与防撞件之间的区域还有利于束缚件穿过以及实现固定，由此实现固定被照射体的功能。
在其中一个实施例中，防撞件至少部分沿平行于延伸方向延伸，并在垂直于延伸方向的方向上突出于侧面设置。优选地，防撞件设置在载置台两两相对相对的侧面，能够避免载置台的相对两侧受到不必要的碰撞。防撞件突出于侧面设置能够保证载置台以及被照射体的安全，避免载置台受到碰撞。
在其中一个实施例中，防撞件至少部分沿平行于延伸方向延伸，并在平行于延伸方向的方向或任意空间上突出于侧面的方向上设置。
在其中一个实施例中，防撞件沿侧面周向设置，防撞件包括沿平行于延伸方向的方向延伸的第一防撞部和第二防撞部，第一防撞部与第二防撞部平行，防撞件还包括沿垂直于延伸方向的方向延伸的第三防撞部和第四防撞部，第三防撞部与第四防撞部平行，第一防撞部的一端与第三防撞部的一端相连，第二防撞部的一端与第三防撞部的另一端相连，第二防撞部的另一端与第四防撞部的一端相连，第四防撞部的另一端与第一防撞部的另一端相连。沿平行于延伸方向延伸的第一防撞部、第二防撞部以及沿垂直于延伸方向延伸的第三防撞部以及第四防撞部，周向包绕地布设在载置台侧面外围。四个防撞部能够避免来自各个方向的碰撞物直接碰撞到载置台上的可能，保证了载置台以及被照射体的安全。优选地，防撞件可以包括多个离散设置的独立防撞部，也可以是一个整体式的防撞件。
在其中一个实施例中，防撞件通过设置于防撞件上的接触部与检测件连接，使得防撞件发生碰撞时，检测件能够采集防撞件触发的信号并进行反馈。接触部设置于防撞件和检测件之间，检测件通过接触部采集防撞件受到碰撞触发的信号。当防撞件先于载置台受到碰撞物碰撞时，防撞件的碰撞信号通过接触部传递给检测件，由此检测件能够采集防撞件触发的碰撞信号，并根据防撞件的碰撞动作进行信号反馈，控制载置台停止运动，实现防碰撞功能。
在其中一个实施例中，检测件设置为沿侧面周向设置并按照预设间隔离散设置的传感器。载置台在移动的过程中，可能会受到外部物件的碰撞，当防撞件受到碰撞时，此时检测件用于任意方向上的采集防撞件触发的碰撞信号，同时还能够进行信号反馈，使得载置台停止移动，从而达到避免载置台遭受碰撞的效果。检测件沿侧面周向设置能够全方位地反馈整个载置台四周的受碰撞情况，进而全面地保证载置台以及被照射体的安全。优选地，检测件可以包括离散设置的至少一个传感器，也可以是一个联动采集防撞件触碰信号的独立传感器。
在其中一个实施例中，检测件与控制系统连接，检测件根据采集到的防撞件触发的信号 向控制系统输入碰撞信号，控制系统根据碰撞信号进行判断并控制载置台停止运动。控制系统与载置台定位装置连接，控制系统用于通过载置台定位装置将载置台移动到指定的坐标位置。在移动的过程中，若载置台外围的防撞件接触到其他物体或者受到其他物体碰撞，此时传感器能够触发信号并传输到控制系统。控制系统根据碰撞的触发信号控制载置台定位装置停止运动，即防止载置台进一步移动，由此避免载置台的进一步碰撞。
本发明的另一方面提供一种放射线照射系统，包括放射源、照射室以及上述任一的支撑装置，放射源用于产生放射线，照射室具有射束出口，用于对被照射体进行放射性照射，支撑装置设置于照射室内。在照射室中，控制装置控制载置台定位装置将载置台移动到定位位置，同时确定被照射体的照射位置，以便载置台上的被照射体在照射位置进行射束的照射。在放射线照射系统中，通过控制载置台定位装置移动载置台，使得照射室的射束出口能够对准被照射体体内的肿瘤细胞，由此实现放射线照射系统对肿瘤细胞的精准治疗。
本发明另一方面提供的放射线照射系统，通过控制系统控制载置台定位装置，使载置台在照射室内移动并定位载置台到理想的照射位置，使得射束能够对准载置台上被照射体体内的肿瘤细胞，从而进行精准的射束治疗；同时能够最大程度地降低对被照射体肿瘤细胞周围正常组织的辐射损伤，给被照射体提供了更加安全、方便、快捷、精准的照射治疗。

参阅图1，图1示出了本发明一实施例中被照射体支撑装置的整体结构示意图，本发明一实施例提供的一种被照射体支撑装置，包括载置台100以及防撞组件200，载置台100用于承载被照射体101(患者)，载置台100限定有延伸方向，载置台100包括沿延伸方向延伸 的支撑表面100a以及与支撑表面100a相连的侧面100b，支撑表面100a用于支撑被照射体101；防撞组件200包括设置于侧面100b的检测件201以及突出于侧面100b设置的防撞件202，防撞件202接触碰撞物并触发检测件201进行信号反馈，优选地，防撞件202先于载置台100接触碰撞物并联动触发检测件201，检测件201根据碰撞动作进行信号反馈。
在一些实施例中，载置台100的支撑表面100a用于支撑被照射体101，载置台100的侧面100b用于安装防撞组件200。载置台100具有外轮廓线(图中未示出)，载置台100的支撑表面100a以及侧面100b在任意方向的投影均限定在外轮廓线的范围内。该被照射体支撑装置不限制载置台侧面100b的位置，例如，从正面(垂直于载置台的延伸方向)或者侧面(朝着载置台的延伸方向)观察载置台100，其侧面100b的竖直边线可以与载置台100的外边缘平齐、可以位于载置台100的外边缘外侧、也可以位于载置台100的外边缘内侧，只要侧面100b与载置台100的支撑表面100a连接即可。优选地，防撞件202突出设置于载置台100的外轮廓线。
在一些实施例中，防撞组件200用于防止外部物件碰撞到载置台100，防撞件202突出于载置台100侧面，即防撞件202超出载置台100边缘的外侧，即载置台100的外轮廓线。当碰撞物朝向载置台100碰撞时，会先触碰到位于载置台100边缘外侧的防撞件202，由此避免载置台100直接受到外部物件的碰撞。防撞件202可以为任意形状，本实施例中防撞件202为圆杆状。载置台100的侧面100b用于设置检测件201，检测件201用于采集防撞件202触发的碰撞信号，并进行信号反馈，使得在移动过程中载置台100能够及时停止移动，保证了载置台100以及被照射体的安全。
参阅图2、图3和图7，图2示出了本发明一实施例中被照射体支撑装置中的载置台与载置台定位装置结合的示意图，载置台100还包括与支撑表面100a相对设置的支撑背面100c，支撑背面100c用于与载置台定位装置300结合，载置台定位装置300用于移动并定位该被照射体支撑装置。在开始照射治疗前，先在模拟定位室(图中未示出)内根据预先制定的治疗计划对载置台100以及被照射体101进行模拟定位：将被照射体101放置到载置台100上，根据制定的治疗计划确定被照射体101的照射部位，根据照射部位对被照射体101进行摆位固定；通过载置台定位装置300将载置台100和被照射体101移动到指定位置，以获得载置台100在模拟定位室中的坐标位置。随后控制系统控制载置台定位装置300将载置台100移动至推车102上，载置台100与载置台定位装置300之间脱离，通过推车102将载置台100移动到照射室601中。到照射室601后进行照射定位：照射室601内的射束出口与定位装置设置与模拟定位室中一致，控制系统根据模拟定位室中及治疗计划中确定的坐标位置，控制载置台定位装置300对载置台100进行移动，移动到位后，载置台100到达照射位置，随后 便可对被照射体101进行照射治疗，进一步地，治疗完毕后控制系统控制载置台定位装置300移动载置台100至推车102上。上述载置台定位装置300在模拟定位室和/或照射室601内移动载置台100的过程中，防撞组件200起到保护载置台100以及被照射体101安全的作用，避免在移动过程中的载置台100受到碰撞。
参阅图3，图3示出了本发明一实施例中被照射体支撑装置中的载置台定位装置以及固定装置的示意图，载置台定位装置300与载置台100之间设置有固定装置400，固定装置400可操作地锁紧和释放载置台定位装置300及载置台100。载置台100定位时，载置台定位装置300通过固定装置400将载置台定位装置300和载置台100之间锁紧，以实现载置台100的定位。载置台100定位结束后，载置台定位装置300移动载置台100至推车102上，通过解锁固定装置400，将载置台定位装置300与载置台100之间脱离，从而将载置台100通过推车102推出模拟定位室或者照射室601。固定装置400能够快速锁紧载置台100和载置台定位装置300，节省了治疗时载置台100与载置台定位装置300之间非必要的锁紧步骤，能够为被照射体101提供快速精准的定位，节省了定位前的操作时间，从而有效地避免了非必要的粒子照射剂量。
再次参阅图1和图6，载置台100上设置有与检测件201间隔设置的束缚件500，束缚件500用于固定被照射体101。当束缚件500固定被照射体101时，束缚件500穿过载置台100和防撞件202之间的区域M并固定。束缚件500可以为弹性束缚件，能够被拉伸和收缩，也可以为非弹性的束缚件，用于将被照射体101的主体固定在载置台100上，便于照射治疗。由于防撞件202突出于载置台100，载置台100和防撞件202之间优选地形成的一个可供穿越的区域M，该区域定义了防撞件202与载置台100之间具有一段间隙，该间隙的设置有利于当防撞件202受到碰撞物碰撞时，该间隙能够间隔开外力对载置台100的影响，同时能够通过接触部203将防撞件202的碰撞动作传递给检测件201，便于检测件201及时采集防撞件202触发的碰撞信号；该间隙的设置还有利于让束缚件500从该间隙穿过，便于将束缚件500固定在载置台100上，对被照射体101进行安全束缚的同时，也不会触发检测件201，干扰到防撞件202的正常使用。在实际使用时，束缚件500的两端可以采用穿过间隙在载置台100两侧进行固定的方式；也可以是束缚件500的一部分位于支撑表面100a的一侧，束缚件500的两端位于并固定在支撑背面100c的一侧；还可以是束缚件500的两端穿过间隙，束缚件500的两端与束缚件500的一部分结合形成独立的束缚件500等。在防撞件202与载置台100之间设置间隙，有利于新增的防撞组件不会影响束缚件500固定被照射体101，还有利于用束缚件500固定被照射体101的同时可以规避对检测件201的影响。
参阅图4，图4示出了本发明一实施例中被照射体支撑装置中的载置台以及防撞件的俯 视图，防撞件202至少包括两根沿平行于延伸方向延伸的防撞杆，防撞件202在垂直于延伸方向的方向上突出于侧面100b设置。防撞件202设置在载置台100的两两相对的侧面，用于避免载置台100两侧受到碰撞。在一些实施例中，防撞件202还可以在平行于延伸方向的方向或任意空间上突出于侧面100b的方向上设置。
参阅图5，图5示出了本发明一实施例中被照射体支撑装置中的载置台以及周向设置的防撞件的俯视图，防撞件202沿侧面周向设置，防撞件202包括沿平行于延伸方向的方向延伸的第一防撞部202a和第二防撞部202b，第一防撞部202a与第二防撞部202b平行，防撞件202还包括沿垂直于延伸方向的方向延伸的第三防撞部202c和第四防撞部202d，第三防撞部202c与第四防撞部202d平行。优选地，第一防撞部202a的一端与第三防撞部202c的一端相连，第二防撞部202b的一端与第三防撞部202c的另一端相连，第二防撞部202b的另一端与第四防撞部202d的一端相连，第四防撞部202d的另一端与第一防撞部202a的另一端相连。防撞件202沿侧面周向设置，即防撞件202设置在载置台100的外围，优选地，本实施例中，防撞件202超出于载置台100的水平投影的外轮廓线，用于避免整个载置台100受到碰撞。第一防撞部202a与第三防撞部202c之间、第二防撞部202b与第三防撞部202c之间、第二防撞部202b与第四防撞部202d之间、以及第四防撞部202d与第一防撞部202a之间，均通过弧形连接部204连接，使得整个防撞件202连接为一个近似矩形的整体，能够全方位地对载置台100起到保护作用。
在一些实施例中，防撞件202还可以不限制为采用两个相对侧面的设置方式，以及采用四个防撞部的设置方式，同样能够达到相同的防碰撞效果。例如，防撞件202可以包括多个独立的防撞部，它们按照预设间隔离散的设置在载置台100的外围；此外，防撞件202还可以是一个整体结构，例如，该整体结构根据载置台100水平投影的外轮廓线设置为一个四边形。多个独立的防撞部组成的防撞件202，或者是呈整体结构的防撞件202，均能够避免来自各个方向的碰撞物直接碰撞到载置台100上，实现防碰撞的功能。
参阅图6，图6示出了本发明一实施例中被照射体支撑装置中的防撞件、检测件以及接触部的位置示意图，检测件201设置于防撞件202与载置台100之间，接触部203设置于防撞件202与检测件201之间，防撞件202发生碰撞时，检测件202能够采集防撞件202触发的信号并进行反馈。优选地，接触部203可用于安装防撞件202，使得防撞件202被固定在载置台100的外围。接触部203还可用于连接防撞件202和检测件201，防撞件202的碰撞动作通过接触部203传递给检测件201，这样检测件201能够实时采集防撞件202触发的信号，从而可以及时控制载置台100停止移动。接触部203可以为块/杆/板/连杆等形状，接触部203的使用形式不限，只要能够传递防撞件202的碰撞动作到检测件201即可。本实施例 中，在第一防撞部202a、第二防撞部202b、第三防撞部202c以及第四防撞部202d上，均设置了多个接触部203。当不同角度不同位置的触碰物触碰到载置台100时，通过接触部203的传递使得检测件201都可以及时检测到碰撞件202触发的信号，提高了检测件201的检测范围。
再次参阅图1，检测件201设置为沿侧面周向设置并按照预设间隔离散设置的传感器。检测件201用于检测防撞件202的触发信号，并进行信号反馈。检测件202可以是压力传感器、红外传感器等等，在实际使用时不限制传感器的类别，只要可以实现采集防撞件202位移和/或受力等信号并能够进行信号反馈即可。例如，当防撞件202受到碰撞时，压力传感器通过接触部203能够感受到防撞件202的受压信号，并能够按照规律将压力信号转换为电信号并输出。传感器按照预设间隔离散设置，优选地，接触部203也随传感器按照预设间隔离散设置。检测件201间隔设置不会影响束缚件500固定被照射体101，同时也有利于全方位分散地检测各个方向触碰物的碰撞。此外，检测件201可以包括离散设置的至少一个传感器，也可以是一个联动采集防撞件202触碰信号的独立传感器，其中通过将离散设置的接触部203设计成连杆的形式集中将多个方向防撞件202的碰撞信号传递到单独的传感器中。
再次参阅图2，检测件201与控制系统连接，检测件201根据采集到的防撞202件触发的信号向控制系统输入碰撞信号，控制系统根据碰撞信号判断并控制载置台100停止运动。控制系统与载置台定位装置300连接，即控制系统用于通过载置台定位装置300来控制载置台100进行移动。控制系统还与检测件201连接，用于接收检测件201输出的碰撞信号。当防撞件201受到碰撞时，检测件201将防撞件202的碰撞信号传递给控制系统，此时控制系统根据碰撞信号控制载置台定位装置300，使得载置台100停止移动，即阻止了载置台100的误碰撞。
参阅图7，图7示出了本发明一实施例中放射线照射系统的示意图，本发明提供一种放射线照射系统，包括放射源、照射室601以及上述任一的被照射体支撑装置，放射源用于产生放射线，照射室601具有射束出口，用于对被照射体101进行放射性照射，支撑装置设置于照射室601内。本实施例中放射线照射系统优选为硼中子治疗系统，放射线照射系统还包括射束产生装置，优选为中子产生装置602、射束整形体603和准直器604。中子产生装置602为放射源，由中子产生装置602产生如质子线的带电粒子线。中子产生装置602产生的中子束依次通过射束整形体603和准直器604照射向载置台100的被照射体101。被照射体支撑装置设置于照射室601内，用于根据模拟定位室中的标记将载置台以及被照射体定位到预设的位置。本领域技术人员知道的是，模拟定位室和照射室601中的治疗相关的装置具有相同的位置关系，即该被照射体支撑装置、射束出口也对应地设置在模拟定位室中。模拟定 位室和照射室内还分别设置有相同的位置关系的激光定位装置，激光定位装置在模拟定位室中给被照射体进行初步的位置标记，根据初步的位置标记能够确定被照射体在照射室601中具有与模拟定位室中相同的位置，随后能够通过射束对被照射体101进行照射治疗。
以上实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
