具体实施方式
下面将结合附图，对本公开一些实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开所提供的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。
除非上下文另有要求，否则，在整个说明书和权利要求书中，术语“包括(comprise)”及其其他形式例如第三人称单数形式“包括(comprises)”和现在分词形式“包括(comprising)”被解释为开放、包含的意思，即为“包含，但不限于”。在说明书的描述中，术语“一个实施例(one embodiment)”、“一些实施例(some embodiments)”、“示例性实施例(exemplary embodiments)”、“示例(example)”、“特定示例(specific example)”或“一些示例(some examples)”等旨在表明与该实施例或示例相关的特定特征、结构、材料或特性包括在本公开的至少一个实施例或示例中。上述术语的示意性表示不一定是指同一实施例或示例。此外，所述的特定特征、结构、材料或特点可以以任何适当方式包括在任何一个或多个实施例或示例中。
术语“第一”、“第二”仅用于描述目的，而不能理解为指示或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，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。如在本说明书和所附的权利要求书中所使用的单数形式“一个”和“该”也包括复数个指示物，除非所述内容明确说明并非如此。在本公开实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
“A和/或B”，包括以下三种组合：仅A，仅B，及A和B的组合。
如本文所使用的那样，“约”或“近似”包括所阐述的值以及处于特定值的可接受偏差范围内的平均值，其中所述可接受偏差范围如由本领域普通技术人员考虑到正在讨论的测量以及与特定量的测量相关的误差(即，测量系统的局限性)所确定。例如，“约”可意味在一个或多个标准偏差内，或者 在所阐述值的±30％、±20％、±10％或±5％以内。
目前治疗肿瘤的治疗设备一般包括机架、治疗床以及激光定位装置。治疗床用来支撑和固定患者。激光定位装置能够发射激光，用以对患者的患病区进行定位。
在一些示例中，治疗设备的激光定位装置是安装在治疗房间的墙壁上，一般需要对墙壁进行改造，安装不便。而且这种方案以墙壁作为安装面，增加额外的安装位置，定位也不准确。在另一些示例中，治疗房间内设置有安装柱，治疗设备的激光定位装置安装在安装柱上。这种方案增加了额外的安装柱，使得整机的零部件增多，零部件较为零散。这两种方案中的激光定位装置均和机架分离，距离机架和治疗床的位置较远，激光照射的精度较低，从而降低定位精度。另外，当激光灯长时间工作时，激光灯会发热，进一步导致热漂移误差，在激光灯远距离照射时更加明显，精度降低得更明显。
图1是根据本公开实施例的激光灯组件100的立体图。图2是根据本公开实施例的激光灯组件100的爆炸图。本公开的实施例提供了一种激光灯组件100，如图1和图2所示，该激光灯组件100包括固定部150、安装部200和激光灯250。安装部200与固定部150转动连接，安装部200能够相对于固定部150绕多个沿不同方向延伸的轴线转动，从而能够调整安装部200相对于固定部150在不同方向上的角度的目的。激光灯250与安装部200相对固定，使得激光灯250可随安装部200一起转动，达到调整激光灯250在不同方向上的角度的目的，从而达到调整激光灯250的发射方向的目的。
需要说明的是，激光灯组件100一般在治疗设备首次安装或激光灯组件100出现较大误差时才进行调整。激光灯组件100正常工作时，激光灯250的发射方向是固定的。当对患者进行定位时，通过治疗床的偏摆，使患者的位置发生偏摆，最终使患者身上预设的标记与激光灯250发出的光线匹配，从而实现对患者的患病区的定位。
在一些实施例中，该激光灯组件100可通过固定部150安装到治疗设备的机架上，从而使得激光灯250的安装基准在机架上，无需增加额外的安装位置，也能够减小激光灯250与机架之间的距离，进而减小激光灯250照射的距离，提高激光灯250照射的精度，从而提高定位精度。另外，激光灯250近距离照射，降低了激光灯250的功率，降低了激光 灯250由于发热而导致的热漂移，进一步提高激光灯250的精度。
在一些实施例中，如图2所示，安装部200包括第一安装部300、第二安装部350和第三安装部400。第一安装部300转动连接于固定部150上，且相对于固定部150绕沿第一方向延伸的第一轴线A1转动(即可绕A1转动)，从而使得第一安装部300与固定部150实现相对转动。第二安装部350转动连接于第一安装部300上，且相对于第一安装部300绕沿第二方向延伸的第二轴线A2转动(即可绕A2转动)，从而使得第二安装部350与第一安装部300实现相对转动。第三安装部400转动连接于第二安装部350上，且相对于第二安装部350绕沿第三方向延伸的第三轴线A3转动(即可绕A3转动)，从而使得第三安装部400与第二安装部350实现相对转动。激光灯250与第三安装部400相对固定，这样一来，使得激光灯250相对于固定部150能够绕三个不同方向转动。
需要说明的是，为了使激光灯250的可调节角度尽量地多一些，第一轴线A1、第二轴线A2和第三轴线A3应不共面，即三者之间两两具有空间夹角，从而使得第一轴线A1、第二轴线A2以及第三轴线A3组成空间坐标系，激光灯250在绕第一轴线A1、第二轴线A2以及第三轴线A3分别转动时，可实现调整激光灯250在三维空间中的位置。
一般地，第一轴线A1、第二轴线A2和第三轴线A3两两之间相互垂直，以进一步提高激光灯250的可调节角度。以下实施例将以上述轴线两两之间相互垂直的方式进行说明。
在一些实施例中，如图1和图2所示，固定部150与第一安装部300之间设有转动调整件，可用来调整第一安装部300的转动角度。同样地，第一安装部300与第二安装部350之间、第二安装部350与第三安装部400之间也可设置转动调整件，分别用来调整第二安装部350、第三安装部400的转动角度。
需要说明的是，以上三处可只在任一处设置转动调整件，也可在其中两处设置转动调整件，还可三处都设置转动调整件，在此不做限定。
在一些实施例中，以上三处均设置有转动调整件，为了便于区分，将设置于固定部150与第一安装部300之间的转动调整件称为第一转动调整件450，将设置于第一安装部300与第二安装部350之间的转动调整件称为第二转动调整件500，将设置于第二安装部350与第三安装部 400之间的转动调整件称为第三转动调整件550。
在一些实施例中，如图1和图2所示，固定部150与第一安装部300之间设有锁紧件，可用来固定第一安装部300与固定部150的相对位置。同样地，第二安装部350与第一安装部300之间、第三安装部400与第二安装部350之间也设有锁紧件，分别用来固定第二安装部350与第一安装部300、第三安装部400与第二安装部350的相对位置。
需要说明的是，以上三处可只在任一处设置锁紧件，也可在其中两处设置锁紧件，还可三处都设置锁紧件，在此不做限定。
在一些实施例中，以上三处均设置有锁紧件，为了便于区分，将设置于固定部150与第一安装部300之间的锁紧件称为第一锁紧件600，将设置于第一安装部300与第二安装部350之间的锁紧件称为第二锁紧件650，将设置于第二安装部350与第三安装部400之间的锁紧件称为第三锁紧件700。
图3是根据本公开实施例的激光灯组件100的固定部150的结构图。图4是根据本公开实施例的激光灯组件100的第一安装部300的结构图。为了实现第一安装部300相对于固定部150的转动，在一些实施例中，如图1至图4所示，固定部150上开设有沿第一方向延伸的第一安装孔151，第一安装部300上开设有沿第一方向延伸的第二安装孔301，第一安装孔151与第二安装孔301通过转轴750转动连接，从而实现第一安装部300相对于固定部150绕沿第一方向延伸的第一轴线A1转动。
这里，描述用语“沿某一方向延伸的孔”，是指该孔的深度(即具有该孔的相应结构的厚度)沿该方向。
在一些实施例中，如图3所示，固定部150上设有沿第二方向延伸的安装块152，第一安装孔151设置于安装块152上。安装块152沿第一方向的尺寸小于固定部150除安装块152之外的其余部分沿第一方向的尺寸。这样，能够减小第一安装部300与固定部150连接后沿第一方向的尺寸，减小了激光灯组件100的整体尺寸。
在一些实施例中，如图4所示，第一安装部300包括第一支撑板302、第一侧板303和第二侧板304，第一侧板303和第二侧板304连接于第一支撑板302的同一侧。第一侧板303和第二侧板304间隔设置。第一侧板303和第二侧板304上都设有第二安装孔301，安装块152位于第 一侧板303和第二侧板304之间。第一安装孔151与第二安装孔301相对，如图1或图2所示，转轴750穿过第一安装孔151和第二安装孔301，实现第一安装部300与固定部150相对转动。
在一些实施例中，转轴750可与第一安装孔151固定连接，并与第二安装孔301转动连接。在另一些实施例中，转轴750可与第一安装孔151转动连接，并与第二安装孔301固定连接。这些方式都可实现第一安装部300相对于固定部150绕沿第一方向延伸的第一轴线A1转动。因此，可根据固定部150与第一安装部300的具体结构选择合适的连接方式。
图7是根据本公开实施例的激光灯组件100中的转轴750的结构图。图8是根据本公开实施例的激光灯组件100被通过第一轴线A1且平行于第三轴线A3的平面所截的截面图。在一些实施例中，如图3和图4所示，第一安装孔151为盲孔，第二安装孔301为通孔，第一安装孔151设有转轴固定螺纹孔157。转轴固定螺纹孔157与紧固件配合以将转轴750固定在第一安装孔151内。如图7和图8所示，转轴750设有固定孔751，转轴750位于第一安装孔151和第二安装孔301内，转轴固定螺钉760穿过固定孔751与转轴固定螺纹孔157配合，从而将转轴750固定在第一安装孔151内，并使转轴750与第二安装孔301转动连接。
在安装时，首先将第一安装孔151与第二安装孔301对齐，再将转轴750依次插入第二安装孔301、第一安装孔151，最后用转轴固定螺钉760将转轴750固定即可。这种方式结构简单，安装方便，便于操作。
为了便于调节第一安装部300与固定部150之间的转动角度，在一些实施例中，如图1和图2所示，激光灯组件100的第一转动调整件450可为螺钉、螺栓或螺柱等具有外螺纹的零件。如图3和图4所示，固定部150与第一侧板303相对的位置设有调整凹槽153，第一侧板303设有第一凸块307。第一凸块307伸入到调整凹槽153内，且与调整凹槽153的槽壁之间具有间隙，调整凹槽153的槽壁设有沿第三方向延伸的第一螺纹孔154，第一转动调整件450穿过第一螺纹孔154能够与第一凸块307抵接。
当顺时针转动第一转动调整件450时，第一转动调整件450能够沿第三方向靠近第一凸块307。当逆时针转动第一转动调整件450时，第 一转动调整件450能够沿第三方向远离第一凸块307。从而改变第一凸块307相对于固定部150的位置，从而使第一安装部300相对于固定部150转动。在这种方式下，用户只需调整第一转动调整件450即可达到改变第一安装部300与固定部150之间的转动角度的目的，便于操作。
当调节第一安装部300与固定部150达到所需的角度后，为了使第一安装部300与固定部150保持在所需的角度，二者需要相对固定。在一些实施例中，如图1至图4所示，激光灯组件100的第一锁紧件600可为螺钉、螺栓等具有螺帽的零件。安装块152靠近第一侧板303的一侧设有沿第一方向延伸的第二螺纹孔155，第一侧板303设有沿第一方向延伸的第一通孔305，第一锁紧件600的一端(这里指远离螺帽的一端)穿过第一通孔305与第二螺纹孔155配合，第一锁紧件600的另一端(这里指螺帽所在的一端)与第一侧板303抵接，从而使得第一侧板303与安装块152实现相对固定，即第一安装部300与固定部150之间实现相对固定。
当然，安装块152靠近第二侧板304一侧也可设置第二螺纹孔155，第二侧板304设置第一通孔305，从而实现第二侧板304与安装块152相对固定，在此不再详述。
需要说明的是，虽然第一安装部300相对于固定部150转动，但转动的角度很小，第一安装部300调整的范围也很小。因此，在一种可能的实现方式中，第一通孔305可为圆孔，该圆孔的孔径比第二螺纹孔155的孔径大，且孔径的差值允许第一安装部300相对于固定部150能够实现所需的角度的调整，使得第一锁紧件600仍然能够穿过第一通孔305与第二螺纹孔155配合。当然，该圆孔的孔径应小于第一锁紧件600的螺帽的尺寸，以避免螺帽不能与第一侧板303抵接的问题。
在另一种可能的实现方式中，第一通孔305可为弧形孔，弧形孔所对应的圆心位于第一轴线A1上，从而使得第一安装部300相对于固定部150转动后，弧形孔始终与第二螺纹孔155相对，第一锁紧件600可穿过第一通孔305与第二螺纹孔155配合。
上述的结构可实现第一安装部300与固定部150相对转动，并在转动到所需的角度后实现相对固定。
图5是根据本公开实施例的激光灯组件100的第二安装部350的结构图。 在一些实施例中，如图5所示，第二安装部350包括第二支撑板351、第三侧板352和第四侧板353，第三侧板352和第四侧板353连接于第二支撑板351的同一侧。第三侧板352位于第二支撑板351靠近第一支撑板302的一端，第四侧板353位于第二支撑板351远离第一支撑板302的一端。第一支撑板302上设有沿第二方向延伸的第三安装孔306，第三侧板352上设有沿第二方向延伸的第一安装轴354，第三安装孔306与第一安装轴354转动连接，从而实现第三侧板352相对于第一支撑板302转动，即实现第二安装部350相对于第一安装部300转动。
为了便于调节第二安装部350与第一安装部300之间的转动角度，在一些实施例中，如图1和图2所示，激光灯组件100的第二转动调整件500可为螺钉、螺栓或螺柱等具有外螺纹的零件。如图4所示，第一支撑板302上设有第二凸块308，第二凸块308向靠近第三侧板352的方向延伸，第二凸块308与第三侧板352沿第三方向的正投影具有重叠，第二凸块308设有沿第三方向延伸的第三螺纹孔309，第二转动调整件500穿过第三螺纹孔309能够与第三侧板352抵接。
当然地，第三螺纹孔309应位于第一安装轴354的外侧，即第三螺纹孔309与第一安装轴354的轴线(即第二轴线A2)沿第一方向的距离应大于第一安装轴354的半径，使得第二转动调整件500与第三侧板352的抵接力的作用点位于第一安装轴354的外侧，以增大转动力矩的半径，从而使第二转动调整件500抵接到第三侧板352上时能够带动第一安装轴354相对于第三安装孔306转动。
当顺时针转动第二转动调整件500时，第二转动调整件500能够沿第三方向靠近第三侧板352。当逆时针转动第二转动调整件500时，第二转动调整件500能够沿第三方向远离第三侧板352。从而改变第三侧板352相对于第一安装部300的位置，从而使第二安装部350相对于第一安装部300转动。在这种方式下，用户只需调整第二转动调整件500即可达到改变第二安装部350与第一安装部300之间的转动角度的目的，便于操作。
在一些实施例中，如图4所示，第一支撑板302可以包括两个第二凸块308，两个第二凸块308分别位于所述第一安装轴354的两侧，两个第二凸块308均设置有第三螺纹孔309。在这种情况下，激光灯组件 100应包括两个第二转动调整件500，两个第二转动调整件500分别抵接在第三侧板352上，且抵接在第一安装轴354的两侧的位置。利用两个第二转动调整件500分别控制第二安装部350相对于第一安装部300的顺时针和逆时针转动，使得第二安装部350与第一安装部300之间的转动调节更加精确和方便。
当调节第二安装部350与第一安装部300达到所需的角度后，为了使第二安装部350与第一安装部300保持在该角度，二者需要相对固定。在一些实施例中，如图1和图2所示，激光灯组件100的第二锁紧件650可为螺钉、螺栓等具有螺帽的零件。如图4和图5所示，第一支撑板302设有沿第二方向延伸的第四螺纹孔310，第三侧板352设有沿第二方向延伸的第二通孔355。第二锁紧件650的一端(这里指远离螺帽的一端)穿过第二通孔355与第四螺纹孔310配合，第二锁紧件650的另一端(这里指螺帽所在的一端)与第三侧板352抵接，从而使得第三侧板352与第一支撑板302实现相对固定，即第二安装部350与第一安装部300之间实现相对固定。
虽然第二安装部350相对于第一安装部300转动，但转动的角度很小，对第二安装部350调整的范围也很小。因此，第二通孔355可为圆孔或弧形孔，其设计原理与第一通孔305的设计原理类似，在此不再赘述。
上述的结构可实现第二安装部350与第一安装部300相对转动，并在转动到所需的角度后实现相对固定。
图6是根据本公开实施例的激光灯组件100的第三安装部400的结构图。为了便于将激光灯250安装到第三安装部400上，在一些实施例中，如图6所示，第三安装部400包括相互分离的第一盖体401和第二盖体402，第一盖体401和第二盖体402能够相互盖合并固定，例如可通过紧固件实现二者之间的固定。第一盖体401设有沿第二方向延伸的第一凹槽403，第二盖体402设有沿第二方向延伸的第二凹槽404，第一凹槽403和第二凹槽404相互对接，可形成用于容纳激光灯250的容纳孔405。在安装时，先将激光灯250放入第一凹槽403内，然后将第二盖体402盖合在第一盖体401上以使第一盖体401与第二盖体402将激光灯250夹持在中间，最后将第一盖体401和第二盖体402固定牢固，从而实现对激光灯250的固定。
为了实现第三安装部400与第二安装部350之间的转动，在一些实施例中，如图5和图6所示，第一盖体401上设有沿第三方向延伸的第二安装轴406，第二支撑板351上设有沿第三方向延伸的第四安装孔356，第四安装孔356与第二安装轴406转动连接，从而实现第三安装部400与第二安装部350之间的转动。
在一些实施例中，如图1、图2、图5和图6所示，第三安装部400位于第三侧板352和第四侧板353之间，第四侧板353上设有出光口357，激光灯250发射的光线可穿过该出光口357。
为了便于调节第三安装部400与第二安装部350之间的转动角度，在一些实施例中，如图1和图2所示，该激光灯组件100的第三转动调整件550可为螺钉、螺栓或螺柱等具有外螺纹的零件。如图5和图6所示，第四侧板353上设有沿第二方向延伸的第五螺纹孔358，第三转动调整件550可穿过第五螺纹孔358能够与第一盖体401抵接。
当然地，第五螺纹孔358应位于第二安装轴406的外侧，即第五螺纹孔358与第二安装轴406的轴线(即第三轴线A3)沿第一方向的距离应大于第二安装轴406的半径，使得第三转动调整件550与第一盖体401的抵接力的作用点位于第二安装轴406的外侧，以增大转动力矩的半径，从而使第三转动调整件550抵接到第一盖体401上时能够带动第二安装轴406相对于第四安装孔356转动。
当顺时针转动第三转动调整件550时，第三转动调整件550沿第二方向靠近第一盖体401。当逆时针转动第三转动调整件550时，第三转动调整件550沿第二方向远离第一盖体401。从而改变第一盖体401相对于第二安装部350的位置，从而使第三安装部400相对于第二安装部350转动。在这种方式下，用户只需调整第三转动调整件550即可达到改变第三安装部400与第二安装部350之间的转动角度的目的，便于操作。
在一些实施例中，如图5所示，第四侧板353可设有两个第五螺纹孔358，两个第五螺纹孔358分别位于第二安装轴406的两侧。在这种情况下，激光灯组件100应包括两个第三转动调整件550，分别抵接在第一盖体401上，且抵接在第二安装轴406的两侧的位置。利用两个第三转动调整件550分别控制第三安装部400相对于第二安装部350的顺 时针和逆时针转动，使得第三安装部400与第二安装部350之间的转动调节更加精确和方便。
当调节第三安装部400与第二安装部350达到所需的角度后，为了使第三安装部400与第二安装部350保持在该角度，二者需要相对固定。在一些实施例中，如图1、图2、图5和图6所示，激光灯组件100的第三锁紧件700可为螺钉、螺栓等具有螺帽的零件。第二支撑板351上设有沿第三方向延伸的第六螺纹孔359。第一盖体401存在超出第二盖体402的部分，该部分设有沿第三方向延伸的第三通孔407。第三锁紧件700的一端(这里指远离螺帽的一端)穿过第三通孔407与第六螺纹孔359配合，第三锁紧件700的另一端(这里指螺帽所在的一端)与第一盖体401抵接，从而使得第一盖体401与第二支撑板351实现相对固定，即第三安装部400与第二安装部350之间实现相对固定。
虽然第三安装部400相对于第二安装部350转动，但转动的角度很小，对第三安装部400调整的范围也很小。因此，第三通孔407可为圆孔或弧形孔，其设计原理与第一通孔305的设计原理类似，在此不再赘述。
上述的结构可实现第三安装部400与第二安装部350相对转动，并在转动到所需的角度后实现相对固定。
图9是根据本公开实施例的激光灯组件100被通过第二轴线A2且平行于第三轴线A3的平面所截的截面图。在一些实施例中，如图3、图5和图9所示，固定部150设有沿第二方向延伸的第五安装孔156，第一安装轴354和第三侧板352设有沿第二方向延伸的第六安装孔360，第五安装孔156、第六安装孔360均与容纳孔405同轴，激光灯250穿过第五安装孔156、第六安装孔360固定在容纳孔405内。这种方式使得激光灯250被固定部150、第一安装部300、第二安装部350以及第三安装部400所包裹，避免激光灯250受到碰撞，同时也提升了整个激光灯组件100的外观。
图10是根据本公开实施例的治疗设备800的主视图。图11是根据本公开实施例的治疗设备800的左视图。如图10和图11所示，本公开的实施例提供一种治疗设备800，包括机架850、滚筒900、治疗床950以及三个上述任一实施例所述的激光灯组件100。
机架850一般固定于地面上。滚筒900转动连接于机架850内，并可绕 机架850的轴线转动，滚筒900上安装有用于发射治疗束的治疗头。治疗床950用于承载患者，并将患者移动到滚筒900内。三个激光灯组件100用于对患者的患病区进行定位。三个激光灯组件100分别安装到机架850的0°、90°以及270°的位置。
如图10所示，这里的0°是指机架850最远离治疗床950的位置。在一些实施例中，治疗床950一般安装在地面上，0°即指机架850的最高点的位置。90°、270°分别为0°位置绕机架850的轴线顺时针(或逆时针)旋转90°、270°的位置。这三个位置以地面为参考，便于定位。
在使用该治疗设备800时，首先将患者固定在治疗床950上，并对患者的患病区做三个十字标记。然后移动治疗床950使患者的患病区靠近三个激光灯组件100组成的平面处。由于激光灯250发出的激光为出光方向相互交叉的两束光(即十字射线)，通过调节患者身上的三个十字标记，使其与激光灯250发出的十字射线对齐，完成对患者的患病区的定位。最后将治疗床950移动到滚筒900内，对患者的患病区进行治疗。
如图11所示，该治疗设备800的激光灯组件100直接安装在机架850靠近治疗床950的端面上，使得三个激光灯组件100对患者的患病区进行定位的虚拟等中心(B点)与滚筒900内的治疗头对患者的患病区进行治疗的实际等中心(C点)之间的距离H得以减小，使得治疗床950向滚筒900内移动的距离减小，降低了治疗床950移动时的误差，提升了对患者的患病区的定位精度和治疗精度。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
