System and method for using a haptic device in combination with a computer-assisted surgery system

摘要

In accordance with an embodiment of the present invention, attractive haptic objects are associated with a target region for performing a medical procedure and repulsive haptic objects are associated with anatomical features to be avoided during the medical procedure. A surgeon may perform surgical planning by moving the haptic device around. The surgeon moves the haptic device until a pose is found where haptic cues from the attractive haptic objects are active indicating that a medical device if attached to the haptic device would reach the target region, and haptic cues from the repulsive haptic objects are inactive indicating that the medical device would not penetrate any of the anatomical features to be avoided. During the planning process a virtual tool may be displayed on a display device to indicate the position and/or movement of the medical device if the medical device had been coupled to the haptic device.
