ROBOTICALLY CONTROLLING REMOTE CENTER OF MOTION WITH SOFTWARE AND GUIDE TUBE

摘要

A robotic surgical system includes a surgical robot and a guide tube. The surgical robot includes a robot arm and a controller. The controller is configured to establish a software-based remote center of motion of a surgical instrument attached to the robot arm based on a location of a surgical portal in a patient through which the surgical instrument is inserted. The guide tube having a trailing end supported by the robot arm of the surgical robot, a leading end inserted in the surgical portal and maintaining alignment between the robotic arm and the surgical portal during a surgical instrument exchange, and an elongated tubular body through which an elongated shaft of the surgical instrument is inserted or removed during the surgical instrument exchange.
