SURGICAL LOCATION MONITORING SYSTEM AND METHOD WITH SURGICAL GUIDANCE GRAPHIC USER INTERFACE

摘要

A position monitoring system comprises a fiducial reference, a tracker for obtaining image information of surgical site, and a computer system with processor, memory, a software program, and access to a database with scan data of the surgical site with the fiducial reference fixed to the site. Uniquely identifiable tracking markers are fixed to the fiducial reference and to a surgical implement. The computer determines the relative positions and orientations of the markers based on live image information from the tracker, relates and displays on one or more display systems the current position and orientation of the fiducial reference and the surgical implement. The computer renders on the one or more display systems a surgical guidance graphic user interface showing planned and actual locations for the surgical implement to impinge on the area of surgical patient, an allowed range of angles of incidence for the surgical implement, and an actual instantaneous angle of incidence of the surgical implement. When the implement is a drill, the graphic user interface may display the drilling depth.

主权项

1. A method for monitoring a surgical site, comprising:
attaching a fiducial key to a location proximate to a surgical site; creating a first scan of the surgical site with the fiducial key attached to the location proximate to a surgical site; rigidly attaching a first tracking marker to the fiducial key; rigidly attaching a second tracking marker to a surgical implement; obtaining image information from an optical tracker proximate the surgical site; communicating the image information from the optical tracker to a computing device; calculating and displaying on a display system, using the computing device, a model of the surgical site based on the scan, the identity of the fiducial key, and the image information received from said tracker; and rendering on the display system a surgical guidance graphic user interface showing at least a planned location for the surgical implement to impinge on the area of surgical patient, an actual instantaneous impingement location for the surgical implement, an allowed range of angles of incidence for the surgical implement to impinge on the instantaneous impingement location, and an actual instantaneous angle of incidence of the surgical implement.
