Ophthalmic orbital surgery apparatus and method and image-guide navigation system
First Claim
1. An apparatus for collecting and processing physical space data for use while performing image-guided surgery with an instrument, the apparatus comprising:
- (a) an endoscope including;
(i) a probe housing having a proximal end, a distal end and a lumen extending between the proximal end and the distal end;
(ii) an image fiber disposed in the lumen that communicates image information from the distal end;
(iii) a purge fluid/gas port disposed at the proximal end of the probe that accepts purge fluid/gas;
(iv) a purge fluid/gas conduit disposed in the lumen and in fluid communication with the purge fluid/gas port, the conduit delivering purge fluid/gas to the distal end of the endoscope; and
(v) an access conduit disposed in the lumen which receives the instrument;
(b) a magnetic tracking system that includes a magnetic tracking tip disposed proximate the distal end of the probe housing and that is configured to detect the magnetic tracking tip in a three dimensional (3-D) physical space; and
(c) an image data processor configured toobtain an image space having a plurality of tomographic images each containing all image information;
determine point-based registrations mapping the 3-D physical space to the image space based on points in the 3-D physical space and corresponding points in the image space;
determine a location and an orientation of the instrument in the image space based on magnetic tracking tip location data generated by the magnetic tracking tip in the 3-D physical space and the point-based registrations; and
dynamically display, while performing the image-guided surgery, (i) a selected one of the plurality of the tomographic images that overlaps the location of the instrument in the image space and (ii) indications of the location and orientation of the instrument in the image space.

Abstract
A flexible endoscope for ophthalmic orbital surgery includes a flexible probe housing having a proximal end, a distal end and a lumen extending between the proximal end and the distal end. The endoscope also includes an image fiber disposed in the lumen that communicates image information from the distal end of the flexible probe, a purge fluid/gas port disposed at the proximal end of the flexible probe that accepts purge fluid/gas and a purge fluid/gas conduit disposed in the lumen and in fluid communication with the purge fluid/gas port. The fluid/gas conduit delivers purge fluid/gas to the distal end of the endoscope. The endoscope also includes an access conduit disposed in the lumen that receives one of an ablation instrument, a coagulating instrument and a medication delivery instrument.
