Surgical Simulator System and Method

摘要

A surgical simulator comprising a haptic arm capable of simulating forces generated during surgery from interactions between a surgical tool and tissue operated upon. The simulator further comprises a visual display capable of depicting a three-dimensional image of the simulated surgical tool and a physics-based computer model of the tissue. The haptic arm controls the movement and orientation of the simulated tool in the three-dimensional image, and provides haptic feedback forces to simulate forces experienced during surgery. Methods for simulating surgery and training users of the simulator are also described.

1. A system for simulating a surgery, the system comprising:
a first haptic arm; a first haptic mechanism in mechanical communication with the first haptic arm, wherein the haptic arm and haptic mechanism are capable of providing haptic force feedback to a user of the system during simulation of a surgery; a haptic control unit capable of signaling to the first haptic mechanism a level of haptic force feedback; a first computer in electronic communication with the haptic control unit and comprising a software module capable of generating a physics-based model of a portion of the human body and calculating the haptic force feedback to be provided by the first haptic arm and first haptic mechanism, wherein the calculated haptic force feedback corresponds to substantially the same forces exerted on a surgical tool when it interacts with the portion of the human body during live surgery; and a simulated microscope capable of displaying a three-dimensional image of the portion of the human body and a simulated first surgical tool simulated by the haptic arm.
