辅助腹腔镜手术机器人穿刺孔位置标定研究

从临床应用的角度出发,针对研制的带有主被动关节的辅助腹腔镜手术机器人被动姿态关节的特点,提出了一种标定患者腹壁穿刺孔位置相对机器人基础坐标系坐标的方法.在机器人小臂的下方安装2个不同倾角的激光源,通过几何关系间接测得患者穿刺孔相对机器人基础坐标系的位置,为机器人控制功能的实现提供了必要的腹腔镜姿态信息.对机器人标定系统进行了实验研究,分析了标定误差产生的原因,研究结果表明该方法可以准确标定出穿刺孔相对机器人基础坐标系的位置,机器人能够完成腹腔镜位姿控制的任务.

Study on assistant laparoscope surgical robot to calibrate puncture

Based on the requirement of clinical application,an assistant laparoscope surgical robot with active and passive joints was developed.The design of passive posture joints can make the robot accord with the demands for actual operation further.With the character of passive joints,a method to calibrate the relative position of patient's puncture to the basic coordinate system of the robot was provided.Two laser lights of different inclinations were installed below the small arm,and through the geometric relat...
