Abstract

The present invention relates to a interactive computer system for use in training persons in surgical procedures in remote locations. The system employs visual, audio and/or textual data bases to provide training to students of such procedures using a personal computer based system with graphics and multimedia capabilities.

Claims

1. A method for providing a user with training in a surgical procedure utilizing a self-contained interactive computer system having a video display, a user interface device, and a memory storage device including a plurality of stored video footage relating to various steps in the surgical procedure, wherein a user selects from among a plurality of available actions relating to the various steps in the surgical procedure, said method comprising the steps of:

(a) providing a plurality of predetermined available actions relating to the surgical procedure on a first portion of the video display;

(b) detecting which of the plurality of such predetermined available actions was selected by the user with the user interface device;

(c) displaying on a second portion of the video display portion of the plurality of stored video footage in the memory storage device corresponding to the predetermined available action selected by the user; and

(d) repeating steps (a) through (c) until either all scenarios relating to the surgical procedure are displayed on the video display, or an erroneous available action is selected by the user.

2. The method of claim 1 wherein the plurality of predetermined available actions provided in step (a) further include a plurality of erroneous surgical actions for testing the user'"'"'s knowledge of the surgical procedure, and the method further comprising the steps of:

providing an error message on the first portion of the video display upon the selection of an erroneous surgical action by the user; and

providing a return option on the first portion of the video display to enable the user to return to a previously depicted scenario.

3. The method of claim 2 wherein the surgical procedure is an ophthalmic surgical procedure.

4. The method of claim 3 wherein the ophthalmic surgical procedure is a PHACO/IOL procedure comprising the steps of incision, capsulotomy, nucleus removal, lens implantation and closure.

5. A method for training users in an ophthalmic surgery procedure with an interactive computer system having a plurality of stored video footage and stored data corresponding to various steps in the ophthalmic surgery procedure, a video display and a user interface device, said method comprising the steps of:

(a) providing an initial main menu on the video display prompting a user to select between a plurality of available procedures displayed on the main menu for treating an ophthalmic condition;

(b) detecting which of the plurality of available procedures is selected by the user with the user interface device;

(c) displaying a video image of an area of an eye on which the selected procedure is to be performed on a first portion of the video display and a plurality of actions corresponding to the selected procedure on a second portion of the video display;

(d) detecting which of the plurality of actions was selected by the user with the user interface device;

(e) updating the first portion of the video display with a portion of the plurality of stored video footage relating to the selected action;

(f) updating the second portion of the video display with a portion of the stored data corresponding to the selected action instructing a user as to the results of the selected action; and

(g) repeating steps (c) through (f) for each subsequent step in the ophthalmic surgery procedure.

6. The method of claim 5 wherein the video display is further provided with a review button, a pause button and forward button display for rewinding, pausing and forwarding the video footage in the first portion of the video display.

7. A method for using an interactive computer system including an output video display, a user interface device and a memory storage system, including a video footage storage portion, a text storage portion and a program data storage portion, to provide training for a surgical procedure selected by a user, said method comprising the steps of:

(a) retrieving a program data from the memory storage system corresponding to the surgical procedure selected by the user;

(b) updating the output video display to display a main menu relating to a plurality of steps corresponding to the surgical procedure selected by the user;

(c) detecting which one of the plurality of surgical steps displayed on the main menu is selected by the sure with the user interface device;

(d) retrieving a video image and video footage from the video footage storage portion of the memory storage system, and program data from the program data storage portion of the memory storage system corresponding to the step selected from the main menu;

(e) displaying the video image on a first portion of the output video display corresponding to the video image retrieved from the video footage storage portion, and a plurality of selectable actions on a second portion of the output video display corresponding to the program data retrieved from the program data storage portion;

(f) detecting a selected one of the plurality of selectable actions displayed on the second portion of the output video display with the user interface device;

(g) displaying updated video footage on the first portion of the output video display corresponding to the selected one of the plurality of selectable actions whereby the output video display is updated with video footage stored in the video footage portion of the memory storage device corresponding to the selected one of the plurality of selectable actions;

(h) updating the second portion of the output video display with text data corresponding to the selected one of the plurality of selectable actions; and

(i) repeating steps (f) through (h) until either all scenarios relating to the surgical procedure are completed or until an erroneous action for the scenario is selected.

8. The method of claim 7 wherein steps (g) and (h) are performed simultaneously on the output video display.

9. The method of claim 7 wherein video footage is displayed on the first portion of the output video display prior to displaying the video image of step (e).

10. The method of claim 7 wherein continuous video footage is displayed on the first portion of the video display instead of displaying the video image in step (e).

11. The method of claim 10 wherein steps (g) and (h) of claim 7 are performed simultaneously on the output video display.
