Description

医用光源装置 技术领域
本发明涉及医疗器械领域，特别是涉及一种医用光源装置。
背景技术
医用氙灯作为一种冷光源，可应用于硬管内窥镜，为硬管内窥镜提供照明。通过导光束将医用氙灯的输出端和硬管镜头连接，医用氙灯提供的照明光斑即可传递给硬管镜头。
一般而言，医用氙灯功率大，输出光斑的亮度很高，但是使用寿命较短，且随着寿命的损耗，输出光斑的亮度会逐渐降低。而在临床手术或检测等操作中往往需要的亮度基本是处在一个固定的范围，基于氙灯的生命周期内输出亮度的不稳定性，或者临床实际操作的需要，必须对到达硬管镜头的输出光斑的亮度进行调节。氙灯模组本身的功率是恒定的，并不能通过电路控制来调节亮度。目前普遍的做法是通过机械调光的方式来控制输出光斑进入导光束的量，以调节到达硬管镜头的输出光斑的亮度。
调节氙灯的亮度时，操作者一方面观察光输出的强度，另一方面也可观察操作面板上的调光指示以便得知调节的程度。例如，现有的一种操作方案中，通过按压按键来调光，且按键旁边的屏幕可显示对应的输出光斑的亮度数值。另外一种操作方案中，通过旋转旋钮来调光，而输出光斑的亮度通过丝印符号来表示。这些方案中虽都能实现输出光斑的亮度调节，但是未能将调光的强弱和调光指示很好的关联起来。
发明内容

具体实施方式
如图1、图2、图3中所示，本发明一实施例提供的一种医用光源装置用于为硬管内窥镜提供照明用光束。所述医用光源装置包括面板38、照明光源1、挡光片31、指示光源365、调节件361和传动机构30。
面板38上设有出光孔4和指示窗41。出光孔4供照明光源1提供的光束输出。出光孔4处可以设置连接结构，例如螺纹、卡扣等，用于与导光束的一端连接，而导光束的另一端可与硬管内窥镜的硬管镜头连接，从而出光孔4输出的光束可为硬管镜头提供照明。
指示窗41供指示光源365提供的光束输出，指示光源365在指示窗41处示出的光束面积大小，表征照明光源1从出光孔4输出的光强大小。例如，当指示窗41被全部点亮时，意味着照明光源1从出光孔4输出的光强最大，当指示窗41被点亮的面积减小时，则意味着照明光源1从出光孔4输出的光强减小。
一实施例中，所述指示窗41的尺寸在调节件361的运动方向上逐渐变化。更具体的，所述指示窗41为弧形槽，且槽宽度逐渐变化。通过设置逐渐变化的宽度，当指示窗41不同程度被点亮时，更容易形象的展示出光孔4所输出的光强大小。另外的一些实施例中，指示窗41可以为直线形槽，槽宽度可以均 匀，也可以由一端至另一端逐渐变化。指示窗41可以是去除部分面板38而形成的孔或槽结构，也可以是面板38上相应部位制作成光学透明而无需开孔。当指示窗41为光学透明面板时，指示窗41可以呈现出具有弧形槽或直线形槽等形状的轮廓。
进一步地，一些实施例中，还对应所述指示窗41处设有进度条37。进度条37设置在面板38与调节件361之间，可具有对指示光源365提供的光束进行加工处理功能，例如可以是具有折射、反射性能的光学元件。进度条37对指示光源365提供的光束进行导向，使指示光源365提供的光束按照预设角度从指示窗41输出，因而观察指示窗41时，可以发现明显的亮暗分界线，进而精确判断指示窗41被点亮的程度。
一些实施例中，所述进度条37本身可为不透光材料制成，而在进度条37上设置多个不连续的孔、槽以形成透光的窗口。亦或者在所述进度条37开设的透光的窗口处进一步设置导光件以对透出的光束进行调节，优化光束从指示窗41处透出的视觉效果。
照明光源1对应所述出光孔4设置。照明光源1可以是氙灯等形式的冷光源。进一步地，所述医用光源装置还包括透镜模组2，所述透镜模组2设置在照明光源1的光输出路径上，照明光源1提供的光束经透镜模组2聚焦后再到达所述面板38的出光孔4。进一步地，还可设置滤光片(图未示)等元件，以对照明光源1提供的光束进行特定波长的过滤。
挡光片31设置在面板38与照明光源1之间。挡光片31由非透光材料制成，同时参考图4，挡光片31上设有透光槽5，所述透光槽5的尺寸沿特定方向逐渐变化。所述照明光源1提供的光束可穿过所述透光槽5后到达所述面板38上的出光孔4。本实施例中，通过操作调节件361，借助传动机构30的带 动，可使挡光片31移动，进而在移动过程中，使透光槽5的不同尺寸部位对准出光孔4，从而可允许照明光源1提供的光束不同程度的通过，也即实现照明光源1输出至出光孔4的亮度调节。本实施例中，所述的特定方向也即挡光片31的移动方向。因透光槽5各部位的尺寸逐渐变化，通过改变挡光片31相对照明光源1的位置，可允许照明光源1提供的光束输出至出光孔4的量被逐渐改变，达到无级调节。在另外的一些实施例中，透光槽5的各部位的尺寸也可呈非连续变化，例如等级变化，从而对照明光源1提供的光束到达出光孔4的量实现不同档位调节。
一实施例中，所述挡光片31整体呈圆形片状，透光槽5呈弧形，且透光槽5的中心线51与以挡光片31中心为圆心的一圆弧重合。透光槽5的两个边缘轮廓均呈弧形，且两边缘之间的间距逐渐变化，从而使透光槽5的宽度沿着中心线51延伸的方向逐渐变化。所述挡光片31通过挡光片转轴32与面板38转动连接。挡光片31与面板38的转动连接可以直接由挡光片转轴32转动设置在面板38上，也可以借助其他中间件实现。通过对调节件361的操作，传动机构30可带动挡光片31绕挡光片转轴32转动，转动过程中，出光孔4、照明光源1与中心线51的不同部位共线。当透光槽5的不同宽度部位对准照明光源1时，则可不同程度地允许照明光源1的光束通过到达出光孔4。
挡光片31的边缘可设置两个限位缺口52，可在面板38上设置与限位缺口52配合的限位件，当挡光片31被旋转使限位缺口52与限位件抵持时，挡光片31不能再被旋转，因而可定位挡光片31的两个极限位置。
另外的一些实施例中，操作调节件361时，挡光片31可以被传动机构30带动作直线运动而非转动，例如挡光片31外形为矩形，挡光片转轴32上以及挡光片31边缘设置啮合的齿条，挡光片转轴32转动时，实现挡光片31平动。 此种情况下，透光槽5的边缘轮廓可以是直线形。
指示光源365用于点亮指示窗41，即指示光源365提供的光束可射出指示窗。指示窗41被点亮的面积大小与照明光源1输出至出光孔4的光强大小对应。指示光源365可以是LED等类型的光源。一实施例中，与指示窗41的形状对应，指示光源365可以呈弧线形排布。在另外的实施例中，指示光源365也可以是直线形排布。指示光源365也可以是矩阵式排布。
调节件361设置在所述面板38上，供使用者操作。所述传动机构30连接在调节件361和挡光片31之间。当操作调节件361时，一方面，所述指示光源365提供的光束射出指示窗41的量被改变，使操作者可观察到指示窗41被不同程度的点亮，与此同时，另一方面，所述传动机构30驱使所述挡光片31移动，使所述透光槽5的不同大小部位对正所述出光孔4，从而调节所述照明光源1提供的光束到达所述出光孔4的量。
本实施例中，当操作调节件361使指示光源365提供的光束射出指示窗41的量增加时(即指示窗的尺寸随调节件的运动变大、例如逐渐变大时)，传动机构30驱使挡光片31移动，使对应出光孔4的透光槽5的尺寸逐渐变大，从而使照明光源提供的光束到达出光孔4的量增大，即实现调亮照明光源并同步指示该调亮过程。当操作调节件361使使指示光源365提供的光束射出指示窗41的量减少时(即指示窗的尺寸随调节件的运动变小、例如逐渐变小时)，传动机构驱使挡光片31移动，使对应出光孔4的透光槽5的尺寸逐渐变小，从而使照明光源提供的光束到达出光孔4的量减小。因而本发明提供的技术方案可将指示窗41用于调光指示的信号与照明光源1输出光的调节较好的关联起来，让调光操作更直观更细致，从视觉上助益使用者对调光状态的判断。
所述指示光源365提供的光束射出指示窗41的量的调节，可以通过多种方式实现。例如，一些实施例中，所述指示光源365设置在所述调节件361上，当操作调节件361时，所述指示光源365相对所述面板38移动，从而使所述指示光源365在指示窗41内露出的面积被改变。
图3、图5、图6中示出了指示光源365结合设置在调节件361上的实施例。具体的，指示光源365设置在一电路板364上，电路板364再借助紧固件366例如螺钉固定于调节件361上。因而操作调节件361时，指示光源365同步移动，从而改变指示光源365相对面板38上的指示窗41的位置。
对应所述指示光源365，可在调节件361上设置开槽371。指示光源365的光束可经开槽371射出而到达指示窗41。进一步地，可在指示光源365上设置导光板363，所述导光板363的一端抵接在开槽371中，导光板363的另一端设置在指示光源365上。导光板363可对指示光源365发出的光束作出整形等调整，使指示光源365透出指示窗41的光束更加符合指向要求。经导光板363传输后的光束可进一步经前述进度条到达指示窗41，为调节件361的调光过程提供视觉效果更好的指示。
进一步地，还可在调节件361上设置位置指示灯367。一实施例中，位置指示灯367与指示光源365均设置在电路板364上。位置指示灯367用于指示调节件361指向指示窗41的具体位置，例如当位置指示灯367指向指示窗41的某一位置并被点亮时，指示窗41的所述某一位置到指示窗41的其中一端为点亮状态，而指示窗41的所述某一位置到指示窗41的另外一端为暗状态，因而位置指示灯367可以成为指示窗41亮暗分界点的标示。如图3中所示，所述调节件361上设有透光孔372，所述位置指示灯367正对所述透光孔372设置。进一步地，可在位置指示灯367上设置导光柱362，所述导光 柱362的一端抵接在透光孔372中，导光柱362的另一端设置在位置指示灯367上。导光柱362可对位置指示灯367发出的光束作出整形等调整，使位置指示灯367发出的光更加精准的从透光孔372射出。
所述指示光源365提供的光束射出指示窗41的量的调节方式还可以为，所述指示光源365相对面板38固定设置且对应所述指示窗41，所述调节件361上设挡光条(图未示)，当操作调节件361时，所述挡光条相对所述面板38移动并不同程度地遮挡所述指示光源365。换言之，指示光源365与面板38的相对位置固定不变，且指示光源365发出的光对准指示窗41。通过调节件361带动挡光条的移动，来改变挡光条遮挡指示光源365射向指示窗41的光的程度。
一实施例中，所述调节件361为旋钮，转动设置在所述面板38上。通过转动操作所述调节件361，来改变指示光源365提供的光束到达指示窗41的量，如图1中所示，通过旋转调节件361使位置指示灯367(与导光柱362对应)从位置A变换到位置B的过程中，指示光源365(与导光板363对应)逐渐露出在指示窗41(与进度条37对应)中，使指示窗41被点亮的面积逐渐变化。同时借助传动机构30带动挡光片31移动，以调节照明光源1输出至出光孔4的光强。
所述调节件361可以直接转动设置在面板38上。例如调节件361可以嵌套在出光孔4处，与出光孔4整合设置在一起。图中所示实施例为所述调节件361的转动中心与出光孔4中心间隔设置，也即与出光孔4分离设置。
如图2、图7和图8中所示，一实施例中，调节件361通过调节件转轴35设置在一载板39(图2、图8中未示出载板39)上，载板39再与面板38固定连接。进一步地，所述挡光片31通过挡光片转轴32也可转动设置在所述载 板39上。
调节件361并非限定为旋钮，还可以是拨杆等形式，对应调节件361的具体形式，指示窗41等元件可以适应变更和匹配，例如当调节件361为拨杆时，指示窗41可以是直线形而非曲线形。
上述实施例中，均是指示窗41设置在面板38上。在另外的一些实施例中，指示窗41也可设置在调节件361上。如图9所示的实施例中，面板38上开设有装配调节件361的装配孔40。调节件361转动设置在该装配孔40处，其中调节件361可包括固定部和调节部，固定部相对于面板固定设置，而调节部可相对于于面板和固定部运动。供指示光源365的光束通过的指示窗41开设在调节件361的固定部上。指示光源365可与调节部固定设置，当操作调节部时，指示光源365随调节部移动，使指示光源365在指示窗41内露出的面积发生变化，进而提供不能点亮程度的调节指示。与此同时，调节部通过前述传动机构带动挡光片运动，改变照明光源提供的光束射出出光孔的量。另外的一个实施例中，所示指示光源365设置在所述调节件361上并对应所述指示窗41。所述面板38上设置挡光条(图未示)，例如挡光条延伸在装配孔40内。当指示光源365与指示窗41之间无其他物件遮挡时，指示光源365点亮指示窗41所有面积。而当操作所述调节件361时，可使设置的所述挡光条不同程度地遮挡指示窗41，从而调节所述指示光源提供的光束射出指示窗的量。
该一实施例中，导光柱362、导光板363、电路板364、位置指示灯367、透光孔372等结构均可参照图3所示的实施例设置，此不一一赘述。需要指出的是，由于指示窗41设置在调节件361上，因而图3所示的实施例中，调节件361上开设的指示窗41即为向外透出指示光的开槽，而且导光板363的一 端抵接在指示窗41处，另一端设置在指示光源365上。
一实施例中，如图2和图7中所示，所述传动机构30为带传动机构，包括设置在调节件转轴35上的第一带轮341、设置在挡光片转轴32上的第二带轮342，以及套设在第一、第二带轮341、342上的传动带33。通过旋转调节件361，再利用传动带33的传动，可同步转动挡光片31。所述传动机构30还可以是齿轮等其他类型的传动机构。
以上所述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。
以上所述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。
