System and method for performing surgical procedure using drill guide and robotic device operable in multiple modes

摘要

System and method for performing a surgical procedure using a drill guide and a robotic device operable in multiple modes. The drill guide is mechanically coupled to the robotic device. A pre-defined virtual trajectory constrains movement of the drill guide. In a first mode, a user is able to manually manipulate the drill guide while movement of the drill guide is constrained by the pre-defined virtual trajectory. In a second mode, the robotic device operates autonomously, for instance, to perform service on the robotic device.

主权项

1. A computer-assisted surgery system for performing a surgical procedure at a target area on a patient's anatomy, said computer-assisted surgery system comprising:
a robotic device having a plurality of joints and a plurality of actuators; a drill guide mechanically coupled to said robotic device, wherein said robotic device is configured to constrain said drill guide according to a haptic object comprising a pre-defined virtual trajectory with said drill guide being movable along said pre-defined virtual trajectory toward the target area on the patient's anatomy; and a computer in communication with said robotic device and configured to command said robotic device to operate in one of a first mode in which said drill guide is manually manipulated by a user or a second mode in which said robotic device operates autonomously, wherein said robotic device is configured to be controlled by said computer to generate haptic feedback in said first mode in response to said drill guide being manually manipulated by the user in said first mode in order to maintain said drill guide along said pre-defined virtual trajectory.
