Description

一种调节机构、光距尺系统和医疗设备 技术领域
本发明涉及医疗器械领域，尤其涉及一种调节机构、光距尺系统和医疗设备。
背景技术
医用加速器光学距离指示尺,简称光距尺(ODI，Optical Distance Indicator)。它是以可见光的形式，指示某一垂直于束流轴的平面至辐射源距离的一种光学装置，在临床上，通过光距尺指示治疗床上的患者与辐射源之间的距离，用于患者的辅助摆位。如果面对光距尺竖立一个包含束流轴的平面，光距尺在该面上投射出一个距离标尺，表示以辐射源为原点的束流轴坐标，如图1所示，光距尺投射出的距离标尺上的刻度表明患者距离辐射源距离。实际光距尺在医疗设备的安装过程中可能会出现一定的偏差，所以需要对其位置和姿态进行一定调整看，但是目前的光距尺系统中不存在用于调节光距尺位置或姿态的调节机构或者存在的调节机构调节能力有限，所以目前需要在光距尺初装后反复的调整，费时费力且不够准确。

具体实施方式
下面将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，所描述的实施例仅仅是本发明一部分实施例，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。
需要说明的是，本发明实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本发明实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
还需要说明的是，本发明实施例中，“的(英文：of)”，“相应的(英文：corresponding，relevant)”和“对应的(英文：corresponding)”有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。
为了便于清楚描述本发明实施例的技术方案，在本发明的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分，本领域技术人员可以理解“第一”、“第二”等字样并不是在对数量和执行次序进行限定。
现有的医疗设备中的光距尺系统在安装完成后缺乏对光距尺位置或姿态调整的有效手段，从而使得光距尺的使用过程中可能存在较大误差。
针对上述问题，本发明实施例提供一种医疗设备，包括一种光距尺系统，参照图2所示，本发明实施提供的医疗设备中的光距尺系统10，包括光距尺11和调节机构12，光距尺11安装在调节机构12上，光距尺11通过调节机构12可以安装在医疗设备上使用，同时可以通过调节机构12对光距尺11的位置和姿态进行调整。
其中光距尺由照明系统、掩模版和投影系统三部分组成，其中，照明系统由光源和照明光学镜头组成，掩模版是用微电子技术在镀膜的光学玻璃上刻出的距离指示刻线和数字，掩模版上的刻线和数字间距等通过成像原理确定；投影系统用于将掩模版上的图案倾斜投射到束流轴所在的竖直平面上，从而达到指示患者和辐射源之间距离的目的；现有的光源一般采用卤素光源，但是卤素光源存在光源因发射较 大引起的寿命较短的缺陷，所以本发明实施例提供的光距尺中的光源采用激光光源或LED(Light Emitting Diode，发光二极管)光源。
由于光距尺投影的像仅在束流轴上是真实的，所以光距尺在垂直于束流轴平面上的投影距离指示仅一点是准确的，即与十字叉丝在垂直于束流轴平面上的交点投影重合的那一点。十字叉丝设置于辐射源外，用来指示束流轴。光距尺在该点指示的距离即是辐射源到该表面的距离。临床上利用这一原理来确定患者体表的辐照入射点到辐射源的距离。在设备安装调试过程中，需要调节光距尺在垂直于束流轴平面上的投影与十字叉丝在该平面上的交点投影重合。在调节过程中不仅需要调整光距尺的整体安装位置，还需要调节光距尺的投影角度。本发明实施例提供的光距尺系统10则可以通过调节机构12的调节作用达到调节光距尺11的位置相对投影面的距离和投影角度的目的。
参照图3所示，本发明实施例的调节机构12，包括光距尺安装架13、第一驱动装置14、第二驱动装置15和安装座16；
光距尺安装架13用于安装光距尺11；
第一驱动装置14与光距尺安装架13连接，第一驱动装置14用于驱动光距尺安装架13绕第一轴线旋转，第一轴线与光距尺11的出光方向垂直；
第二驱动装置15与第一驱动装置14连接，第二驱动装置15用于驱动第一驱动装置14和光距尺安装架13沿第二轴线移动，第二轴线与第一轴线垂直；第二驱动装置15固定于安装座16上。
参照图3和图4所示，第一驱动装置14包括翻转支架141和第一驱动件142；
光距尺安装架13铰接在翻转支架141上，可相对于翻转支架141绕第一轴线旋转；第一驱动件142设置在翻转支架141上，用于驱动光距尺安装架13相对于翻转支架141绕第一轴线旋转。
具体的，参照图4所示，一种可实现的方式中，光距尺安装架13可以为中心带有通孔具有一定厚度的板材，其中通孔用于夹设光距尺11，其中光距尺11可以如图5所示，其安装配合面用于与光距尺安装架13中的通孔配合，安装止口则用于限制光距尺11的安装位置；为了保证光距尺安装架13可以更好的夹设光距尺11，光距尺安装架13的一角断开形成第一夹紧端131和第二夹紧端132，这断开的两部分 上则设置有相对的螺纹孔，其中第一夹紧端131的螺纹孔为通孔，通过螺栓和螺纹孔的配合便可以实现对光距尺安装架13的放松或锁紧，以达到固定或放松光距尺11的目的，当然，此处光距尺安装架13采用其余的断开方式和锁紧结构均可，此处仅为一种可实现的方式。
参照图4和图8所示，为了实现光距尺安装架13和翻转支架141之间的铰接关系，光距尺安装架13相对的两侧正对设置有第一过孔133和第二过孔134(图8中示出)；第一过孔133和第二过孔134的孔径中心的连线为第一轴线；
翻转支架141包括支撑臂1411以及正对设置的第一限位臂1412和第二限位臂1413，第一限位臂1412上设置有第三过孔1414，第一过孔133和第三过孔1414通过第一销轴17配合铰接；第二限位臂1413上设置有与第三过孔1414正对的第四过孔1415，第二过孔134和第四过孔1415通过第二销轴18配合铰接；
实际中铰接的方式不限于使用销轴和通孔配合，还可以采用其他任意方式，只要能达到使光距尺安装架13相对于翻转支架141旋转即可，此处仅为一种实现方式的示例，不做具体限制；
因为在实际旋转过程中为了保证销轴不脱落且光距尺安装架13可以自由旋转，第三过孔1414的孔径大于第一过孔133且第四过孔1415的孔径大于第二过孔134；或者，第一销轴17位于第一过孔133的部分的直径大于位于第三过孔1414的部分的直径，且第二销轴18位于第二过孔134的部分的直径大于位于第四过孔1415的部分的直径。
可选的，参照图4和图8所示，为了进一步保证光距尺安装架13在旋转过程中销轴不脱落，该调节机构还包括第一锁紧销19和第二锁紧销20；翻转支架141上还设置有垂直于第一过孔133的第五过孔1416和垂直于第二过孔134的第六过孔1417；第一锁紧销19(图8中未示出)与第五过孔1416配合用于相对于翻转支架141锁紧第一销轴17，第二锁紧销20(图8中未示出)与第六过孔1417配合用于相对于翻转支架141锁紧第二销轴18。
进一步的，参照图4、图6和图7所示，为了实现光距尺安装架13可相对于翻转支架141旋转的目的，在一种可实现的方式中，翻转支架141的支撑臂1411上设置有和第一过孔133垂直的第一螺纹通孔14111，光距尺安装架13除设置有第一过孔133和第二过孔134的两 侧以外的，靠近支撑臂1411的一侧设置有和第一螺纹通孔14111相对的翼部135；为了保证调节过程中的平衡，第一螺纹通孔14111一般设置在支撑臂1411的中心位置；
第一驱动件142包括形成有螺纹的第一驱动杆1421(螺纹未图示)，第一驱动杆1421通过螺纹旋设于第一螺纹通孔14111中，驱动杆穿过第一螺纹通孔14111的一端与翼部135抵接；
第一驱动件142用于通过旋转第一驱动杆1421以驱动光距尺安装架13相对于翻转支架141绕第一轴线转动，以达到对光距尺11出射光的俯仰角度的调整；一种可实现的方式中，第一驱动件142可以为螺栓。
可选的，为了保证在对光距尺安装架13和光距尺11的调节完成后固定位置，该调节机构还包括第一锁紧件21，用于相对于第一驱动装置14松开或锁紧光距尺安装架13；一种可实现的方式中，参照图4、图6和图7所示，第一锁紧件21包括第一螺栓211、第二螺栓212和拉杆213，拉杆213上设置有第二螺纹通孔2131和第三螺纹通孔2132；
支撑臂1411上还设置有平行于第一螺纹通孔14111的第四螺纹通孔14112和第五螺纹通孔14113，翼部135上还设置有正对第四螺纹通孔14112的第一通孔1351(图4未示出)和正对第五螺纹通孔14113的第二通孔1352(图4未示出)；因为旋转过程中翼部135必然会和支撑臂1411的位置产生偏差，如果采用完全相同的正对通孔(螺纹通孔和通孔)会导致调节受阻，所以这里第一通孔1351的孔径大于第四螺纹通孔14112，第二通孔1352的孔径大于第五螺纹通孔14113；
可选的，这里第四螺纹通孔和第五螺纹通孔也可以为通孔，只要能起到配合锁紧功能即可；
拉杆213设置在翼部135远离支撑臂1411的一面或设置在支撑臂1411远离翼部135的一面；
第二螺纹通孔2131、第一通孔1351和第四螺纹通孔14112通过第一螺栓211配合，第三螺纹通孔2132、第二通孔1352和第五螺纹通孔14113通过第二螺栓212配合；第一螺栓211和第二螺栓212通过对拉杆213、翼部135和支撑臂1411的锁紧或放松，以相对于翻转支架141松开或锁紧第一驱动装置14；
具体的，为了保证锁紧过程中，光距尺安装架13不会产生除需 要调节的方向以外的倾斜偏差，第四螺纹通孔14112和第五螺纹通孔14113分别位于第一螺纹通孔14111的两边且以第一螺纹通孔14111为对称中心轴对称。
可选的，一种可实现的方式中，参照图3和图4所示，第二驱动装置15包括支架安装板151和第二驱动件152；
支架安装板151固定于安装座16上；第一驱动装置14活动组装在支架安装板151上，可相对于支架安装板151沿第二轴线移动；第二驱动件152设置在支架安装板151上，用于驱动第一驱动装置14和光距尺安装架13相对于支架安装板151沿第二轴线移动。
进一步可选的，参照图4和图7所示，在一种可实现的方式中，为了保证第一驱动装置14和其上安装的光距尺安装架13可以沿光距尺11光出射的方向移动以调整光距尺11位置，第一驱动装置14上设置有凸起部1418；参照图4所示，支架安装板151上开设有导槽1511，凸起部1418伸入导槽1511中且能够沿导槽1511运动；导槽1511的中轴线为第二轴线；一种可实现的方式中，导槽1511可以为U形导槽。
进一步的，参照图4所示，为了保证达到对第一驱动装置14和光距尺安装架13的驱动，支架安装板151相对于导槽1511的一端还设置有第六螺纹通孔1512，第二驱动件152包括形成有螺纹的第二驱动杆1521，第二驱动杆1521通过螺纹旋设于第六螺纹通孔1512中，第二驱动杆1521穿过第六螺纹通孔1512伸入导槽1511中与凸起部1418抵接；

可选的，参照图4所示，为了保证第二驱动件152在使用过程中，不从第六螺纹通孔1512中滑出，第二驱动件152还包括设置第二驱动杆1521上且与支架安装板151抵接的螺母1522。
可选的，参照图4和图7所示，该调节机构还包括第二锁紧件22，用于相对于第二驱动装置15松开或锁紧第一驱动装置14；一种可实现的方式中，第二锁紧件22包括垫片221和第三螺栓222；凸起部1418上设置有第一螺纹孔14181(图10和图11中示出)，第三螺栓222从 支架安装板151远离第一驱动装置14的一侧穿过垫片221旋设于第一螺纹孔14181中，用于相对于支架安装板151松开或锁紧第一驱动装置14。
示例性的，第二锁紧件22、凸起部1418、第一驱动装置14和第二驱动装置15的具体结构如图11所示。
在一种可实现的方式中，第一驱动装置14、第二驱动装置15、光距尺安装架13和光距尺11安装完成后的立体图如图12所示。
在一种可实现的方式中，第一驱动装置14、第二驱动装置15、安装座16和光距尺安装架13安装完成后的主视图和对应的剖面图如图9和图10所示，其中各部分的标号可参照图4，图9和图10中未全示出。
可选的，参照图3所示，安装座16包括光尺安装座161和光尺转接板162；第二驱动装置15固定安装在光尺安装座161上；光尺安装座161固定安装在光尺转接板162上。
进一步可选的，光尺转接板162的第一端固定安装有光尺安装座161，光尺转接板162的第二端设置有腰型槽，以使光尺转接板162通过螺栓固定安装在医疗设备上；参照图2、图3和图4所示，在一种可实现的实现方式中，安装座16包括光尺安装座161和光尺转接板162，光尺安装座161可以为存在四面壁的箱体，第二驱动装置15中的支架安装板151位于导槽1511的两侧通过螺栓和螺纹通孔(或通孔)的配合，安装在光尺安装座161正对的两壁上，其余两壁中的一壁则通过螺栓和螺纹通孔(或通孔)的配合安装在光尺转接板162上；
光尺转接板162则包括第一安装板1621、承接板1622和第二安装板1623，承接板1622位于第一安装板1621和第二安装板1623之间，第一安装板1621和承接板1622之间存在第一预设角度，第二安装板1623和承接板1622之间存在第二预设角度，第一安装板1621、承接板1622和第二安装板1623之间形成Z形结构；第二安装板1623用于通过螺栓和螺孔与光尺安装座161的一壁固定，第一安装板1623则通过腰型槽和螺栓安装在医疗设备上，这里腰型槽可以为四个；因为腰型槽和螺栓配合安装后可以沿腰型槽轴线方向进行移动，所以这样设计也可以对光距尺11的位置和姿态进行一定的调整。
需要说明的是，本发明实施例中提供的第一驱动杆1421和第二驱动杆1521既可以是人工转动，也可以是电机驱动驱动杆转动，驱动过 程不做具体限制。
具体的，在前述实施例中，因为通过第一驱动杆1421上的螺纹每转一圈引起的驱动杆的移动距离、第一轴线距离第一驱动杆1421和凸起部1418抵接点的距离，是可以计算得出相应的光距尺11俯仰角的调整角度的，所以本发明实施例提供的方案可以对光距尺11的俯仰角度进行精确调节；而第二驱动杆1521上的螺纹每转一圈引起的驱动杆的移动距离则为第一驱动装置14移动的距离，所以本发明实施例提供的方案可以对光距尺11的移动距离进行精确调节；另外光尺转接板162上的腰型槽对光距尺11位置的改变也是可以直接获知的，所以综上，本发明实施例提供的技术方案，不仅可以实现对光距尺11位置和姿态的调整，也可以精确的控制调整角度或距离的大小(例如，可以在第一驱动件142和第二驱动件152上标刻度指示调整角度或距离的大小)。
本发明实施例提供的调节机构、光距尺系统和医疗设备，该调节结构包括：光距尺安装架、第一驱动装置、第二驱动装置和安装座；光距尺安装架用于安装光距尺；第一驱动装置与光距尺安装架连接，第一驱动装置用于驱动光距尺安装架绕第一轴线旋转，第一轴线与光距尺的出光方向垂直；第二驱动装置与第一驱动装置连接，第二驱动装置用于驱动第一驱动装置和光距尺安装架沿第二轴线移动，第二轴线与第一轴线垂直；第二驱动装置固定于安装座上。本发明实施例提供的技术方案中，在光距尺系统中增加调节机构，其中，第一驱动装置可以调节光距尺绕第一轴线旋转，而第一轴线与光距尺的出光方向垂直，从而可以调整光距尺的出射光的俯仰角度；第二驱动装置则可以驱动第一驱动装置和安装光距尺的光距尺安装架沿第二轴线移动，而第二轴线与第一轴线垂直，也就是说第二驱动装置可以使得光距尺沿着出射光方向(平行于第二轴线的出射光方向)进行运动；所以上述实施例提供的技术方案可以对光距尺进行两个方向上的调整，保证光距尺在使用时的位置准确和姿态准确；进一步的，因为旋转角度和移动距离是可以精确控制的，所以上述实施例能够达到对光距尺位置和姿态的精确调整。
以上所述，仅为本发明的具体实施方式，但本发明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发明揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以权利要求的保护范围为准。
