具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
图1所示为本申请一实施例提供的连接组件、准直器以及射束整形体组件的结构示意图。如图1所示，本申请实施例所提供的连接组件6包括：内环结构1、与内环结构1套装的外环结构2以及安装结构3。内环结构1和外环结构2同心设置，且内环结构1和外环结构2通过安装结构3与准直器5装配，以便通过连接组件6将准直器5与射束整形体组件4可拆卸连接。
示例性地，内环结构1和外环结构2可以是薄片状的环状结构。内环结构1和外环结构2可以均为防止活化的材料，比如铝合金。内环结构1和外环结构2的材料也可以不一样，本申请对此不做具体限定，只要内环结构1和外环结构2是防止活化的材料即可。
示例性地，安装结构3可以是环扣或者锁扣等结构。只要安装结构3能够将准直器5装配到内环结构1和外环结构2上即可。
应当理解，外环结构2半径大于内环结构1半径，内环结构1半径大于准直器5连接端面半径。
本申请实施例提供的连接组件6，内环结构1和外环结构2同心设置，且内环结构1和外环结构2通过安装结构3与准直器5装配，从而实现准直器5和射束整形体组件4的可拆卸连接。在不使用其他任何工具的情况下，依靠单人操作便可完成对有脚准直器5的安装和拆卸，大幅度提高工作效率。除此之外，通过设置包括内环结构1、外环结构2以及安装结构3的连接组件6，对准直器5进行限位和固定，以取代原本需要人工拧紧螺栓7的操作，进一步提升拆卸安装的操作精度、更换的便利性、设备整体的使用寿命，以及中子捕获治疗装置进行放射治疗的可靠性，减少了更换过程中设备的磨损。
图2所示为本申请一实施例提供的准直器的结构示意图。图3所示为本申请一实施例提供的内环结构和外环结构的结构示意图。图4所示为本申请一实施例提供的连接组件和准直器的结构示意图。结合图1至图4所示，准直器5为有脚准直器，安装结构3包括三个环扣30，分别为上环扣30、左环扣30以及右环扣30，内环结构1固定连接射束整形体组件4上，三个环扣30通过螺栓7等间隔固定在射束整形体组件4上。当三个环扣30打开时，将外环结构2套装到内环结构1上。当内环结构1和外环结构2固定后，利用外环结构2和三个环扣30的相互配合，将外环结构2相对内环结构1运动，从而对有脚准直器5进行锁紧固定。
本申请实施例提供的连接组件6，外环结构2通过三个环扣30固定在内环结构1上，通过运动外环结构2对准直器5进行限位和固定，从而实现有脚准直器5和射束整形体组件4的可拆卸连接，使得准直器5的安装和拆卸过程更加简单方便，而且减少了现有技术中因频繁拆卸准直器5上的螺栓7造成的磨损。
在本申请其他实施例中，安装结构3也可以是四个环扣30或者五个环扣30等。本申请对环扣30的数量不做具体限定，只要内环结构1和外环结构2能够通过安装结构3与准直器5装配即可。
在一实施例中，如图2至图4所示，有脚准直器5包括至少一个连接部50，内环结构1包括至少一个限位块10以及与至少一个连接部50适配的至少一个预留槽9，连接部50用于插入预留槽9，限位块10用于限位外环结构2与内环结构1之间的运动。
示例性地，限位块10可以是限位开关，也可以是安装在内环结构1上的螺丝或者焊接在内环结构1上的凸起。限位块10用于限制外环结构2相对内环结构1的最大运动位置。
示例性地，预留槽9的数量可以设置为一个或多个。预留槽9的形状包括但不限于圆形、多边形、倒圆角以及倒斜角。预留槽9的形式可以是凸起或者凹陷。本申请对预留槽9的类型和数量不做具体限定，只要与有脚准直器5的连接部50相适配即可。
示例性地，连接部50为有脚准直器5的连接脚。连接部50的数量可以设置为一个或多个。连接部50的形状包括但不限于圆形、多边形、倒圆角、三角形以及倒斜角等。本申请对连接部50的数量和形状不做具体限定，只要与预留槽9相适配即可。
示例性地，外环结构2的运动轨迹可以为环形或直线。
在一实施例中，继续如图2至图4所示，有脚准直器5包括三个连接部50，三个连接部50等间隔设置在有脚准直器5的安装面上。内环结构1上 开设有三个预留槽9，三个预留槽9与三个连接部50一一相对应。将外环结构2向右转动，当触及到内环结构1上的限位块10时，将有脚准直器5的三个连接部50分别对应插入预留槽9中，然后将外环结构2向左运动，合紧并压住有脚准直器5，则有脚准直器5被锁死固定。
本申请实施例提供的连接组件6，通过外环结构2相对内环结构1运动，合紧并压住有脚准直器5的连接部50，实现有脚准直器5与内环结构1和外环结构2的固定安装。除此之外，进一步在内环结构1上设置限位块10，能够有效限制外环结构2相对内环结构1的运动行程。
本实施例中的有脚准直器5的安装过程大体如下：可以通过沿预定方向转动或移动外环结构2或环扣30，使外环结构2和与外环结构2固定的环扣30相对内环结构1发生运动，从而使预留槽9可以对外敞开形成足够容置连接部50的空间，然后，可以将有脚准直器5的连接部50插入预留槽9中，由此可以将有脚准直器5置于所述内环结构2内，接着，可以通过沿相反于预定方向转动或移动外环结构2或环扣30，这时环扣30可以带动有脚准直器5的连接部50运动，直至有脚准直器5的连接部50与预留槽9的一侧槽壁抵接。优选地，为了使预留槽9可以对外敞开形成足够容置连接部50的空间，并且使外环结构2相对内环结构1的运动处于较佳的可控状态，此时固定设置在内环结构1上的限位块10可以对外环结构1或环扣30抵接，这样可以设定外环结构1的运动最大幅度以及预留槽9对外敞开的空间体积，从而方便操作人员作业。
在一实施例中，如图3和图4所示，连接组件6还包括至少一个定位柱8，定位柱8配合内环结构1用于限位外环结构2相对内环结构1的运动。
示例性地，定位柱8的数量可以设置为一个或多个。定位柱8的形状可以是圆形、椭圆形或多边形。本申请对定位柱8的形状和数量不做具体限定，只要定位柱8能够配合内环结构1对外环结构2相对内环结构1的运动进行限位即可。
具体而言，外环结构2和内环结构1相互配合，合紧并压住有脚准直器5的三个连接部50，从而将有脚准直器5与内环结构1和外环结构2固定安装。按下内环结构1上的定位柱8，便可以对外环结构2相对内环结构1的运动进行限位，从而进一步实现对有脚准直器5的锁紧固定。当需要转动外环结构2时，只需要拔起定位柱8，便能够解除运动限位。换言之，在有脚准直器5安装前或对有脚准直器5拆除前，可以拔起定位柱8，使得外环结构2和内环结构1处于能够相对运动的状态。在有脚准直器5安装完成时，可以将定位柱8插入，使得外环结构2和内环结构1处于锁定状态。
本申请实施例提供的连接组件6，通过定位柱8配合内环结构1对外环结构2相对内环结构1的运动进行限位，从而使得外环结构2和内环结构1的相对位置固定，避免因相对位置发生偏移造成连接组件6的不稳定。

示例性地，环扣30可以是在外环结构2上枢转运动的卡扣。外环结构2与至少一个环扣30固定连接射束整形体组件4。
应当理解，外环结构2与至少一个环扣30可以是卡扣连接，也可以是通过螺栓连接。本申请对外环结构2与至少一个环扣30的连接方式不做具体限定，只要外环结构2与至少一个环扣30实现固定连接即可。
示例性地，紧固件31可以是滑块。滑块能够在外环结构2对应的槽内 沿着直线滑动或沿着外环圆周环形滑动。其中，紧固件31设置有凹槽32，便于用户通过凹槽32拉动紧固件31。如图8所示，环扣30与紧固件31装配完成。如图9所示，紧固件31在环扣30中向左滑动。应当理解，紧固件31的滑动方向可以是向左，也可以是向右，可以根据实际情况确定。紧固件31的形状可以是弧形，还可以是其他形状，只要与外环结构2对应的槽相适配即可，在此不做特殊限定。
具体而言，紧固件31和环扣30相适配，至少一个环扣30和至少一个紧固件31都固定安装在外环结构2上。外环结构2和至少一个环扣30固定在射束整形体组件4上，内环结构1通过至少一个环扣30套装到外环结构2上，然后将准直器5装配到内环结构1上，并利用紧固件31进一步锁紧固定准直器5。其中，准直器5和内环结构1可以是卡接，也可以是插接。本申请实施例提供的连接组件6，外环结构2和至少一个环扣30紧固在射束整形体组件4上，内环结构1通过至少一个环扣30固定在外环结构2上。将准直器5与内环结构1装配，通过至少一个紧固件31进一步锁紧固定准直器5，本申请使准直器5的安装和拆卸能够单人、无工具完成，进一步提高了工作效率，将原本需要人工拧螺栓7固定准直器的操作改为机械结构限位固定，提高了操作精度以及系统放射治疗的可靠性。
图10所示为本申请一实施例提供的内环结构的结构示意图。图11所示为本申请一实施例提供的内环结构和外环结构的结构示意图。图12所示为本申请又一实施例提供的连接组件和准直器的结构示意图。结合图2、图5至图12所示，准直器5为有脚准直器5，有脚准直器5包括三个连接部50，内环结构1包括与三个连接部50适配的三个预留槽9，连接部50用于插入预留槽9，紧固件31用于合紧并压住连接部50，以便锁死固定有脚准直器5。

本实施例中的有脚准直器5的安装过程大体如下：将内环结构1放入外环结构2内，将环扣30通过旋转或者卡扣或者螺栓的方式，将内环结构1与外环结构2固定；接着将有脚准直器5放入内环结构1的预留槽9内，然后使紧固件31发生运动，合紧并压住有脚准直器5，则有脚准直器5被锁死固定。

图13所示为本申请另一实施例提供的准直器的结构示意图。图14所示为本申请另一实施例提供的内环结构的结构示意图。图15所示为本申请一实施例提供的外环结构的结构示意图。图16所示为本申请一实施例提供的内环结构和准直器的结构示意图。图17所示为本申请另一实施例提供的外环结构和内环结构的结构示意图。图18所示为本申请又一实施例提供的连接组件和准直器的结构示意图。结合图13至图18所示，准直器5为无脚准直器5，内环结构1包括两个连接脚11，外环结构2包括与连接脚11适配的预留槽9，内环结构1与无脚准直器5的连接端卡接，连接脚11用于插入预留槽9，紧固件31用于合紧并压住连接脚11，以便锁死固定无脚准直器5。
示例性地，如图15所示，将内环结构1卡在无脚准直器5的连接端，从而实现内环结构1和无脚准直器5的固定装配。如图18所示，内环结构1的连接脚11对应插入外环结构2的预留槽9中，然后将内环结构1和无脚准直器5装配在外环结构2上。将紧固件31向左转动，合紧并压住内环 结构1的连接脚11，则无脚准直器5被固定在射束整形体组件4碳纤维板的表面上。
由于内环结构1和外环结构2都是薄片状的安装结构3，外环结构2与碳纤维板紧密安装配合或嵌合，内环结构1也基本与碳纤维面板齐平，所以本申请实施例提供的连接组件6，与射束整形体组件4装配的准直器5正下方高度没有突出的物体。当病人采取平躺的姿势接受照射时，其需要治疗的头颈部贴近准直器5出口，肩膀紧贴准直器5正下方，不受突出物体干扰，使病人在头部照射时能贴紧准直器5射束中心，保证病人受照射的射束强度效率。
本申请一实施例提供了一种连接组件的装配方法，连接组件6包括内环结构1、与内环结构1套装的外环结构2以及安装结构3，该方法包括：将内环结构1和外环结构2同心设置；将内环结构1和外环结构2通过安装结构3与准直器5装配，以便通过连接组件6将准直器5与射束整形体组件4可拆卸连接。本申请实施例提供的连接组件6，能够使准直器5稳固安置在射束整形体组件4上，在不使用其他任何工具的情况下，能单人操作实现准直器5的安装和拆卸。
在本申请一实施例中，连接组件6还包括至少一个定位柱8，准直器5为包括至少一个连接部50的有脚准直器5，安装结构3包括至少一个环扣30，内环结构1包括至少一个限位块10以及与至少一个连接部50适配的至少一个预留槽9，将内环结构1和外环结构2通过安装结构3与准直器5装配，以便通过连接组件6将准直器5与射束整形体组件4可拆卸连接，包括：将内环结构1和至少一个环扣30固定连接至射束整形体组件4。将外环结构2通过至少一个环扣30套装内环结构1。如图3所示，拔起至少一个定位柱8，将外环结构2相对内环结构1转动直至抵接限位块10，连接组件6未装入准直器5且处于旋开状态。如图4所示，将连接部50插入预留槽9后，将外环结构2复位，并按下至少一个定位柱8，以便锁紧固定有脚准直 器5。
具体而言，内环结构1和至少一个环扣30均固定连接至射束整形体组件4，当环扣30打开时，将外环结构2套装到内环结构1上。将外环结构2相对内环结构1转动，使外环结构2上的接合部随着外环结构2一起运动，到达内环结构1的限位块10时，合上环扣30，从而内环结构1和外环结构2实现固定装配，然后将准直器5的连接部50都插入内环结构1的预留槽9中，将外环结构2转动回到初始位置，合紧并压住准直器5的连接部50，则准直器5被固定。
在本申请一实施例中，安装结构3包括至少一个环扣30以及与至少一个环扣30滑动连接的至少一个紧固件31，准直器5为有脚准直器5，有脚准直器5包括至少一个连接部50，内环结构1包括与至少一个连接部50适配的至少一个预留槽9，将内环结构1和外环结构2通过安装结构3与准直器5装配，以便通过连接组件6将准直器5与射束整形体组件4可拆卸连接，包括：如图11所示，将外环结构2和至少一个环扣30固定连接至射束整形体组件4；将内环结构1通过至少一个环扣30和至少一个锁紧件固定连接外环结构2。如图12所示，将准直器5的至少一个连接部50插入至少一个预留槽9。如图5所示，将至少一个紧固件31相对外环结构2运动，合紧并压住至少一个连接部50，以便锁死固定有脚准直器5。
在本申请一实施例中，安装结构3包括至少一个环扣30以及与至少一个环扣30滑动连接的至少一个紧固件31，准直器5为无脚准直器5，内环结构1包括至少一个连接脚11，外环结构2包括与至少一个连接脚11适配的至少一个预留槽9，将内环结构1和外环结构2通过安装结构3与准直器5装配，以便通过连接组件6将准直器5与射束整形体组件4可拆卸连接，包括：如图17所示，将外环结构2和至少一个环扣30固定连接至射束整形体组件4；将内环结构1通过至少一个环扣30和至少一个锁紧件31固定连接外环结构2。如图18所示，将至少一个连接脚11插入至少一个预留槽9； 将至少一个紧固件31相对外环结构2运动，合紧并压住至少一个连接脚11，以便锁死固定无脚准直器5。
本申请一实施例提供了一种准直器5，包括上述任一实施例所提及的连接组件6，连接组件6用于固定准直器5。
应当理解，该准直器5中的连接组件6同样能够实现准直器5和射束整形体组件4的可拆卸连接。
本申请一实施例提供了一种中子捕获治疗装置，包括射束整形体组件；以及上述任一实施例所提及的准直器5。
在中子捕获治疗装置实际治疗过程中，不同患者的肿瘤大小和肿瘤位置也会不同，并且对中子射束的照射范围要求也不一样，而中子射束照射范围的限定与准直器5有直接的关系，因此不同情况的肿瘤需要采用不同口径的准直器5。同样，准直器5与肿瘤之间的相对位置也需要根据具体情况来进行调整，以利于中子捕获治疗装置对肿瘤的照射。在本申请实施例提供的中子捕获治疗装置中，在不使用其他任何工具的情况下，能单人操作实现准直器5的安装和拆卸能够实现拆卸，提高了工作效率。同时，将原本需要人工拧螺栓7的操作改为机械结构限位固定，提高了操作精度以及中子捕获治疗装置放射治疗的可靠性。除此之外，对于将准直器5从射束整形体组件多次拆卸所产生的磨损，可以通过定期更换磨损件来提高整个中子捕获治疗装置的经济性和稳定性。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或者暗示相对重要性或者隐含指明所指示的技术特征的数量，由此，限定“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内，所作的任何修改、等同替换等，均应包含在本申请的保护范围之内。
