During freehand performance of vitreoretinal microsurgery the surgeon must perform precise and stable maneuvers that achieve surgical objectives and avoid surgical risk. Here, we present an improved smart handheld microsurgical tool which is based on a ball lens fiber optic sensor that utilizes common path swept source optical coherence tomography. Improvements include incorporation of a ball lens single mode fiber optic probe that increases the working angle of the tool to greater than 45 degrees; and increases the magnitude of the distance sensing signal through water. Also presented is a cutting function with an improved ergonomic design.
在进行徒手玻璃体视网膜显微手术时，外科医生必须执行精确且稳定的操作，以实现手术目标并避免手术风险。在此，我们展示一种改进的智能手持式显微手术工具，该工具基于一个利用共光路扫频源光学相干断层扫描技术的球透镜光纤传感器。改进之处包括采用了一个球透镜单模光纤探头，它将工具的工作角度增加到大于45度；并增强了通过水的距离传感信号的强度。还展示了一种具有改进人体工程学设计的切割功能。
