OBJECTIVES/HYPOTHESIS: To introduce a novel method of combining robotics and the CO(2) laser micromanipulator to provide excellent precision and performance repeatability designed for surgical applications.
Pilot feasibility study.
We developed a portable robotic controller that appends to a standard CO(2) laser micromanipulator. The robotic accuracy and laser beam path repeatability were compared to six experienced users of the industry standard micromanipulator performing the same simulated surgical tasks. Helium-neon laser beam video tracking techniques were employed.
The robotic controller demonstrated superiority over experienced human manual micromanipulator control in accuracy (laser path within 1 mm of idealized centerline), 97.42% (standard deviation [SD] 2.65%), versus 85.11% (SD 14.51%), P = .018; and laser beam path repeatability (area of laser path divergence on successive trials), 21.42 mm(2) (SD 4.35 mm(2) ) versus 65.84 mm(2) (SD 11.93 mm(2) ), P = .006.
Robotic micromanipulator control enhances accuracy and repeatability for specific laser tasks. Computerized control opens opportunity for alternative user interfaces and additional safety features.
目的/假设：介绍一种将机器人技术与 CO2 激光微操纵器相结合的新方法，旨在为手术应用提供卓越的精度和性能重复性。
试点可行性研究。
我们开发了一种便携式机器人控制器，可附加到标准的 CO2 激光微操纵器上。将机器人的准确性和激光束路径重复性与六位经验丰富的行业标准微操纵器用户进行比较，这些用户执行相同的模拟手术任务。采用氦氖激光束视频跟踪技术。
机器人控制器在准确性（激光路径与理想化中心线相差 1 毫米以内）方面优于经验丰富的人工手动微操纵器控制，97.42%（标准差 [SD] 2.65%），而 85.11%（SD 14.51%），P =.018；以及激光束路径重复性（连续试验中激光路径发散的面积），21.42 平方毫米（SD 4.35 平方毫米），而 65.84 平方毫米（SD 11.93 平方毫米），P =.006。
机器人微操纵器控制可提高特定激光任务的准确性和重复性。计算机控制为替代用户界面和附加安全功能提供了机会。
