Image-guided surgery (IGS) is any surgical procedure where the surgeon uses tracked surgical instruments in conjunction with preoperative or intraoperative images in order to directly or indirectly guide the procedure. Image guided surgery systems use cameras,ultrasonic, electromagnetic or a combination or fields to capture and relay the patient's anatomy and the surgeon's precise movements in relation to the patient, to computer monitors in the operating room. This is generally performed in real-time though there may be delays of seconds or minutes depending on the modality and application.
Methods and systems for setting trajectories and target locations for image guided surgery
A system for performing image-guided surgery includes an instrument having a first portion configured to define a trajectory into the body of a patient, a marker device and a user-interface component. A sensing device receives electromagnetic signals that are reflected or emitted from the marker device, and a processing system, coupled to the sensing device, includes at least one processor configured with processor-executable instructions to perform operations that include tracking the position and orientation of the instrument relative to the patient based on the signals received at the sensing device, receiving a signal from the user-interface component of the instrument indicating a user-input event, and saving the trajectory into the body of the patient defined by the first portion of the instrument in response to receiving the signal.
