Minimally invasive surgical training using robotics and tele-collaboration
InactiveUS6852107B2Cosmonautic condition simulationsMechanical/radiation/invasive therapiesMini invasive surgeryEngineering
A medical system that allows a mentor to teach a pupil how to use a robotically controlled medical instrument. The system may include a first handle that can be controlled by a mentor to move the medical instrument. The system may further have a second handle that can be moved by a pupil to control the same instrument. Deviations between movement of the handles by the mentor and the pupil can be provided as force feedback to the pupil and mentor handles. The force feedback pushes the pupil's hand to correspond with the mentor's handle movement. The force feedback will also push the mentor's hand to provide information to the mentor on pupil's movements. The mentor is thus able to guide the pupil's hands through force feedback of the pupil handles to teach the pupil how to use the system.

System, method and devices for navigated flexible endoscopy
The invention provides a method and system for performing an image-guided endoscopic medical procedure. The invention may include registering image-space coordinates of a path of a medical instrument within the anatomy of a patient to patient-space coordinates of the path of the medical instrument within the anatomy of the patient. In some embodiments, the image space coordinates of the path of the medical instrument may be predicted coordinates such as, for example, a calculated centerline through a conduit-like organ, or a calculated “most likely path” of the medical instrument within the anatomy of the patient. In other embodiments, the path of the medical instrument may be an actual path determined using intra-operative images of the patient's anatomy with the medical instrument inserted therein. The registered instrument may then be navigated to one or more items of interest for performance of the endoscopic medical procedure.
