Abstract | A cannula system and method for accessing a blood mass in the brain. The system comprises a cannula with a camera mounted on the proximal end of the cannula with a view into the cannula lumen and thesurgical field below the lumen. A prism, reflector or other suitable optical element is oriented between the camera and the lumen of the cannula to afford the camera a view into the cannula while minimizing obstruction of the lumen. The system may also include an obturator with a small diameter shaft and a large diameter tip which is optically transmissive, so that a surgeon inserting or manipulating the assembly can easily see that the obturator tip is near brain tissue (which is white) or blood (which is red).
用于进入大脑中血块的套管系统和方法。该系统包括套管,该套管具有安装在套管近端上的摄像机,其中可看到套管内腔和内腔下方的手术区域。棱镜、反射器或其他合适的光学元件定向在摄像机和套管的内腔之间,以使摄像机能够看到套管,同时最小化内腔的阻塞。该系统还可以包括具有小直径轴和大直径尖端的阻塞器,该尖端是光学透射的,使得插入或操纵组件的外科医生可以容易地看到阻塞器尖端靠近脑组织(白色)或血液(红色)。 |
