摘要: 微创手术给外科机器人提出了较高的灵活性要求,但是机器人很难具有完全灵 活的工作空间.首先提出象限分割的方法,即把手术工作空间分割为8个象限,确定微创外 科机器人所需灵活工作空间只需要为手术工作空间的1/8.然后,给出微创外科机器人灵活 工作空间与工作空间之间的解析关系, 从而确定机器人的运动学参数.在此基础上,对自行 设计的微创外科机器人结构进行了运动学参数优化设计.这种方法有效降低了微创外科机器 人的灵活性要求,解决了机器人结构尺寸与灵活性之间的矛盾.

Abstract: Although it is difficult for surgical robot to have full dexterous workspace, surgical robot must have high dexterity orienting to minimally invas ive surgery. Firstly, according to the practical requirement of surgery, quadran t segmentation principle was proposed. The surgical workspace was divided into 8 quadrants, so the dexterous workspace occupied only eighth workspace. And then, the analysis relation was derived between dexterous workspace and workspace of surgical robot. The workspace area of surgical robot could be obtained from the analysis relation, and then the kinematics parameters of surgical robot could be confirmed. Finally, kinematics parameters of the self-defined surgical robot w e re optimized. Therefore, this principle decreases the demand on dexterity of sur gical robot and resolves the conflict between structure and dexterity of robot.
