Ophthalmic orbital surgery apparatus and method and image-guided navigation system
First Claim
1. A flexible endoscope for ophthalmic orbital surgery comprising:
- (a) a flexible probe housing having a proximal end, a distal end and a lumen extending between the proximal end and the distal end;
(b) an image fiber disposed in the lumen that communicates image information from the distal end of the flexible probe;
(c) a purge fluid/gas port disposed at the proximal end of the flexible probe that accepts purge fluid/gas;
(d) 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
(e) an access conduit disposed in the lumen that receives one of an ablation instrument, a coagulating instrument and a medication delivery instrument.

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.

19. A method of performing minimally invasive ophthalmic orbital surgery using an endoscope and an image-guided navigation system, the method comprising:
-
(a) scanning tissue of the patient using a scanning device to acquire, store and process a 3-D reference of tissue prior to the tissue being surgically exposed, wherein the image data processor creates a triangularized mesh based on the scanned tissue, determines the volumetric center of a particular portion of the tissue to be ablated, coagulated or medicated during the surgery, and implements an algorithm using the triangularized mesh and the physical space data collected by the instrument to determine the point-based registrations;
(b) surgically exposing an area of tissue proximate the ophthalmic orbit of a patient;
(c) inserting a distal end of the endoscope into the exposed area, the endoscope having a magnetic tracking tip disposed proximate the distal end of the endoscope;
(d) detecting the magnetic tracking tip using a magnetic scanner configured to detect the magnetic tracking tip in three dimensional space;
(e) communicating magnetic tracking tip location data to the image-guided navigation system;
(f) determining point-based registrations used to indicate surgical position in both image space and physical space; and
(g) using the registrations determined in step (f) to map into image space, image data describing the physical space of the endoscope used to perform the image-guided surgery and the tissue. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
