Description

带照明的插管
技术领域
以下描述的发明涉及用于治疗肿瘤的微创手术的领域。
背景技术
中风是导致死亡和致残的神经系统疾病的常见原因。在美国，每年约有700,000名患者患有中风。出血性中风占每年中风人数的20％。出血性中风源自脑部中的血管破裂，从而导致血流到脑组织中并导致脑部中出现血肿(血块)。及时清除血块对于限制或预防长期脑损伤是必要的。
血块和任何周围手术区域的清晰显影和成像有助于去除血块。在美国专利10,172,525中，我们公开了在插管的近端上安装有摄像头的插管，以观察插管导管腔以及管腔内和下方的组织。在该系统中，照明由安装于插管的远端的LED提供或通过从插管的近端延伸到其远端的光纤提供。
发明内容
下面描述的装置和方法使用插管系统提供了体内病变组织的改良显影，该插管系统包括具有近侧安装的摄像头的插管，其中，由安装到插管的近端的光源提供照明。插管系统包括插管导管，在插管导管的近端上安装有摄像头组件，视轴被指向插管的远端，以获得插管导管的远端附近的手术工作空间的视图。为了提供充足的照明，同时最大限度地减少眩光，该插管系统包括具有宽光束角的效力大的封装LED，其结合额外的透镜以将LED的输出聚焦到窄光束角。包括LED、基板/芯片和主透镜在内的市售的封装LED配备有包含窄聚焦透镜的辅助光学器件，以减小整个组件的光束角。辅助光学器件可包括GRIN透镜，其被配置成将来自LED的光聚焦到窄光束角以通过插管传输到插管的远端处的工作空间。例如，对于内径为9mm的13cm长的插管，透镜可被配置成提供约3.5°的输出光束角。
附图说明
图1示出了一名需要手术干预的脑部中有血块的患者，其中，插管已被插入到脑部中，插管的远端靠近该血块。
图2、图3和图4示出了具有LED和聚焦透镜的插管系统，这些聚焦透镜被配置成使传输到插管导管中的光的光束角变窄。
图5示出了图1、图2和图3所示的照明组件的细节。
图6、图7和图8示出了没有棱镜的照明组件，其中，光轴与插管导管的长度对齐。
具体实施方式
图1、图2和图3示出了可被方便地用在微创手术中的插管系统。图1示出需要进行外科手术干预的脑部3中具有病变组织2的患者1，其中，插管4已被插入到病变组织中，插管的远端靠近病变组织。病变组织可以是脑部中的神经胶质瘤或成恶性胶质瘤、脊柱中的室管膜瘤或其他病变组织。
摄像头5被安装在插管的近侧边缘上，摄像头的一部分悬置在插管的边缘并被设置在插管的管腔的上方，并且可操作以获得插管远端的视频或静止图像，其包括插管远端处的目标组织，例如脑部和脑部中的任何病变组织。如图1、图2和图3所示，插管包括具有远端6d的插管导管6，该远端6d适于插入到患者体内。摄像头组件5被固定到插管的近端6p。摄像头组件包括成像传感器7和棱镜、反射器或其他反射镜结构或光学元件8，其悬置在插管导管的管腔9。优选地，为了在脑部中使用，摄像头组件的一部分(例如棱镜、反射器或反射镜)延伸到由插管导管的管腔限定的圆柱形空间中并且向近侧延伸超过插管的近端，并且与插管的近端隔开，并且仅略微延伸到圆柱形空间中。摄像头组件的最远侧光学表面(无论它是在没有棱镜的情况下使用的棱镜8的远侧表面，还是视轴指向插管的远端的物镜的远侧表面)都位于插管导管的近端，且优选地被设置在插管导管的近端的近侧。
如图2和图3所示，插管还包括一个或多个具有输出光束轴11的照明组件10。照明组件包括光源12和相关的光学器件，如果存在的话，其在图示中包括具有输出轴14的棱镜13(在本实施例中，输出轴14与照明组件的输出光束轴11重合)以及透镜15和16，其可在此配置中用于将来自光源的光引导到管腔中，瞄准插管导管的远端的工作空间并朝向目标组织瞄准。图1还示出了控制系统17，其被配置成且可操作以操作光源，获得由摄像头捕获的视频图像数据，并生成/转换相应的视频图像数据以在显示屏18上显示。摄像头组件和照明组件可被在插管导管的近端的近侧支撑和保持在安装结构19上，在该实施例中，安装结构19包括被固定在插管导管的近端上方的直径大于插管的环。
图2、图3、图4和图5示出了照明组件10的结构。这些照明组件包括光源12、棱镜13和位于透镜和棱镜之间的透镜16。光源的特征在于光束轴12B和宽光束角α，该宽光束角α可能是未带透镜的LED或具有被配置成将来自LED的光聚焦成宽光束角的透镜的封装LED的结果。封装LED通常以包括基板、发光二极管本身和覆盖该发光二极管的透镜的形式提供。在白光LED的情况下，封装LED还可包括磷光体(以将来自二极管的一些蓝光转换成红光和绿光，以产生发出白光的封装件)。封装LED的典型光束角可处于30°到180°的范围内。当在图1到图4的插管系统中使用时，该宽光束角将会导致过度眩光，该过度眩光使得使用摄像头组件获得的图像模糊。为了减少这种眩光，透镜15是以凸透镜或梯度折射率透镜(GRIN透镜)或准直透镜的形式提供的聚焦透镜，其用于将来自封装LED的光聚焦成更窄的光束角。封装LED和透镜的适用组合是(1)
Figure BDA0003508112690000031
XQEAWTLED和(2)Edmunds#64-520 GRIN透镜，其可从爱特蒙特光学有限公司(Edmunds Optics)获得。GRIN透镜因其对于给定聚焦能力的小横截面(垂直于其光轴的横截面)而是优选的，这有助于将照明组件放置在插管导管的近端上。棱镜优选地为直角棱镜，但可以使用不同形式的棱镜，以适应GRIN透镜的光轴(在本示例中为长轴)16L、输出光束轴11和插管导管的中心轴6L之间的不同角度。整个照明组件具有对应于棱镜的视轴的输出光束轴，并且输出光束轴11与聚焦透镜的光轴16L成一角度(在图2、图3、图4所示的示例中)。在直角棱镜的情况下，聚焦透镜的光轴可垂直于棱镜的视轴。照明组件的最远侧光学表面(无论它是棱镜13的远侧表面还是聚焦透镜的远侧表面(其中，在不使用棱镜的情况下，聚焦透镜光轴指向插管的远端，如图6和图7所示)位于插管导管的近端，并且优选地被设置在插管导管的近端的近侧。
照明组件可在封装LED和透镜之间配置有气隙20并在透镜和棱镜之间配置有气隙21。通过使用
Figure BDA0003508112690000032
XQEAWT led和Edmunds#64-520 GRIN透镜的这种组合，以照明组件光束轴10B为中心的合成光束角β为约3.5°。
图6和图7示出了没有棱镜的照明组件，其中，(聚焦透镜的)光轴16L与插管导管6的长度对齐。该实施例的其他特征类似于图2至图4的特征，其包括插管4和插管导管6、摄像头组件5和棱镜8。LED被布置成使得光束轴12B向远侧指向插管管腔并朝向插管导管的远端，其中，透镜16被设置成其光轴16L与LED光束轴对齐并且还朝向插管管腔和插管导管的远端指向远侧。在该配置中，棱镜不是必需的。本实施例中的整体照明组件具有与聚焦透镜的光轴相对应的输出光束轴，并且该输出光束轴被指向插管导管的远端。
在图7的俯视图中，示出了光源和相应的透镜16和LED光源12以及摄像头组件5和摄像头棱镜8的位置，其中，光源和摄像头棱镜以有限程度悬置于插管导管6的管腔9，从而允许照明和显影插管导管的远端处的工作空间，同时还允许工具通过插管导管插入到工作空间中。图8示出了具有光源12的照明组件10与其光束角α之间的关系，其将光传输到GRIN透镜16中，光以窄光束角β沿着照明组件光束轴11离开GRIN透镜。
取决于插管的尺寸，输出光束角可稍大或稍小。对于例如长7cm、内径为16mm的相对短而宽的插管，约10°至15°、更为优选地为约13°的窄光束角将在眩光减少的情况下提供良好的照明。对于内径为9mm、长14cm的插管，约3°至5°、更为优选地约3.1°的窄光束角将在眩光减少的情况下提供良好的照明。更一般地，光源和提供小于约20°的输出光束角的聚焦透镜的配置可被用于提供具有最小眩光的良好照明。
图示示出了与GRIN透镜的光轴重合的GRIN透镜的光束轴(离开透镜的光的中心)，可以通过将LED相对于GRIN透镜的纵向中心(其通常为光轴)偏心定位来改变光束轴。这将致使图6和图7中的GRIN透镜的输出光束轴相对于与光轴平行的方向偏离。因此，LED被放置成使得LED的光束轴相对于GRIN透镜的光轴偏离，这将致使GRIN透镜的输出光束轴位于与光轴相同的轴线上。输出光束轴因此可瞄准插管的远侧开口的中心，以与插管导管的中心轴线(或其他特征)相交，而照明组件输出保持在插管导管的圆周附近。
照明组件和插管的配置使得照明组件的最远侧光学表面进入插管管腔或管腔上方的空间的侵入最小，使得外科医生可将手术工具穿过插管，同时照明组件被设置在插管导管的近端上以照亮插管的远端处的手术区域，并且摄像头还具有最远侧的光学表面，其被设置为对插管管腔或管腔上方的空间的侵入最小，使得外科医生可将手术工具穿过插管，同时将摄像头设置在插管的近端上方。提供窄输出光束的照明组件的益处允许在插管的末端提供摄像头和一个或多个照明组件，并且仍然允许手术导管进入到插管中，该插管系统可被配置有一个或多个照明组件，其在摄像头的近端上并未设置摄像头，以在待与其他位置提供的摄像头或显微镜一起使用的插管中提供具有最少眩光的照明。
尽管已经参考研发装置和方法的环境描述了装置和方法的优选实施例，但它们仅是对本发明的原理的说明。多种实施例的元件可被结合到其他种类中的每一个中以获得与这些其他种类相组合的这些元件的益处，并且可以在实施例中单独或彼此组合地使用多种有益特征。在不脱离本发明的精神和所附权利要求的范围的情况下，可以设想到其他实施例和配置。
