Abstract

A method includes receiving image data, receiving surgical procedure data, and generating an operation plan. The image data is associated with anatomical structures in a nasal cavity of a patient. The image data and the surgical procedure data are received through a computing system. The act of generating an operation plan includes identifying a path for a surgical instrument in accordance with the image data and in accordance with the surgical procedure data. The act of generating the operation plan is performed through a computing system. The act of generating an operation plan further includes generating one or more instructional images depicting the identified path for the surgical instrument in a depiction of anatomical structures in the nasal cavity of the patient.

First claim

I/We claim:

1 . A method comprising:
(a) receiving image data, wherein the image data is associated with anatomical structures in a nasal cavity of a patient, wherein the image data is received through a computing system; (b) receiving surgical procedure data, wherein the surgical procedure data is received through a computing system; and (c) generating an operation plan, wherein the act of generating the operation plan is performed through a computing system, wherein the act of generating an operation plan comprises:
(i) identifying a path for a surgical instrument in accordance with the image data and in accordance with the surgical procedure data, and
(ii) generating one or more instructional images depicting the identified path for the surgical instrument in a depiction of anatomical structures in the nasal cavity of the patient.

2 . The method of claim 1 , wherein the image data comprises data from a plurality of CT images.

3 . The method of claim 1 , further comprising processing the image data to generate a three-dimensional image of anatomical structures in the nasal cavity of the patient.

4 . The method of claim 1 , wherein the one or more instructional images include a three-dimensional image of anatomical structures in the nasal cavity of the patient.

5 . The method of claim 4 , wherein the one or more instructional images further include a three-dimensional arrow indicating the identified surgical instrument path in the three-dimensional image of anatomical structures in the nasal cavity of the patient.

6 . The method of claim 1 , wherein the act of receiving surgical procedure data comprises receiving input indicating selection of a surgical procedure.

7 . The method of claim 6 , wherein the act of receiving surgical procedure data further comprises retrieving surgical data from a database in accordance with the received input indicating selection of a surgical procedure.

8 . The method of claim 1 , wherein the act of receiving surgical procedure data comprises receiving a selection of a transparency level for one or more anatomical structures in the nasal cavity of the patient in at least one of the one or more instructional images.

9 . The method of claim 1 , wherein the act of receiving surgical procedure data comprises receiving a selection of a field of view to be depicted in at least one of the one or more instructional images.

10 . The method of claim 1 , wherein the act of receiving surgical procedure data comprises receiving input indicating a path for a surgical instrument relative to one or more anatomical structures in the nasal cavity of the patient.

11 . The method of claim 1 , further comprising applying a sino-nasal structure recognition algorithm to the received image data.

12 . The method of claim 1 , further comprising manipulating the image data to highlight an outflow tract associated with at least one paranasal sinus of the patient.

13 . The method of claim 1 , further comprising:
(a) receiving an endoscopic video image from an endoscope inserted into the nasal cavity of the patient; and (b) presenting the endoscopic video image while simultaneously presenting the one or more instructional images.

14 . The method of claim 13 , wherein the one or more instructional images and the endoscopic video image are presented simultaneously through a single display screen.

15 . The method of claim 14 , wherein the one or more instructional images and the endoscopic video image are presented simultaneously through separate image panels of the same display screen.

16 . The method of claim 13 , wherein the act of presenting the endoscopic video image while simultaneously presenting the one or more instructional images comprises superimposing an instrument path indicator on the endoscopic video image.

17 . The method of claim 1 , further comprising:
(a) receiving position data from a position sensor of a surgical instrument; and (b) incorporating the position data into the one or more instructional images to depict actual positioning of the surgical instrument in relation to planned positioning of the surgical instrument, wherein the planned positioning of the surgical instrument is based on the identified path.

18 . The method of claim 1 , wherein at least one of the one or more instructional images comprises a video image.

19 . A method comprising:
(a) receiving image data, wherein the image data is associated with anatomical structures in a nasal cavity of a patient, wherein the image data is received through a computing system; (b) receiving surgical procedure data, wherein the surgical procedure data is received through a computing system; and (c) generating at least one instructional image identifying a path for a surgical instrument in accordance with the image data and in accordance with the surgical procedure data, wherein the act of generating the at least one instructional image is performed through a computing system; wherein the at least one instructional image includes a representation of a surgical instrument positioned and oriented in accordance with the identified path in a depiction of anatomical structures in the nasal cavity of the patient.

20 . A method comprising:
(a) receiving image data, wherein the image data is associated with anatomical structures in a nasal cavity of a patient, wherein the image data is received through a computing system; (b) receiving surgical procedure data, wherein the surgical procedure data is received through a computing system; and (c) generating at least one instructional image identifying a path for a surgical instrument in accordance with the image data and in accordance with the surgical procedure data, wherein the act of generating the at least one instructional image is performed through a computing system; wherein the at least one instructional image shows a moving representation of a surgical instrument along the identified path in a depiction of anatomical structures in the nasal cavity of the patient.
