Abstract
Abstract A system for use in performing surgery comprises a video camera for generating a video signal encoding an image of organs of a patient, a display operatively connected to the video camera for displaying the image in response to the video signal, and an identification device operatively connected to the video camera for automatically analyzing the video signal to identify organs in the image. The identification device is operatively connected to the display for displaying symbols on the display to identify at least one of the organs in the image.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
138 words
A method for use in performing surgery, comprising the steps of: disposing a laparoscopic trocar sleeve in a skin surface of a patient; inserting at least a portion of a laparoscopic video camera device through said trocar sleeve and at least partially into the patient; upon insertion of said camera device through said trocar sleeve, operating said camera device to generate a video signal encoding video data pertaining to internal organs of the patient; displaying on a display a video image of said organs in response to said signal; automatically analyzing said signal to identify organs in said image; and while maintaining at least a substantial portion of said image on said display, displaying identification symbols on said display, in overlap with a portion of said image, to identify at least one of the organs in said image.
Claim 2
Independent Claim
138 words
A method for use in performing surgery, comprising the steps of: disposing a laparoscopic trocar sleeve in a skin surface of a patient; inserting at least a portion of a laparoscopic video camera device through said trocar sleeve and at least partially into the patient; upon insertion of said camera device through said trocar sleeve, operating said camera device to generate a video signal encoding video data pertaining to internal organs of the patient; displaying on a display a video image of said organs in response to said signal; automatically analyzing said signal to identify organs in said image; and while maintaining at least a substantial portion of said image on said display, displaying identification symbols on said display, in overlap with a portion of said image, to identify at least one of the organs in said image.
Claim 3
Dependent Claim
54 words

Claim 4
Dependent Claim
19 words
The method defined in claim 2, further comprising the step of signaling said computer to display said identification symbols.
Claim 5
Dependent Claim
18 words
The method defined in claim 1 wherein said symbols include a name for said one of said organs.
Claim 6
Dependent Claim
32 words
The method defined in claim 1, further comprising the steps of automatically identifying abnormal structural conditions of said organs and providing an alert signal upon detecting any one of said abnormal conditions.

Claim 10
Dependent Claim
55 words
The method defined in claim 1, further comprising the step of performing a laparoscopic surgical operation on the patient, said steps of operating, displaying said image, analyzing, and displaying identification symbols being executed during said operation,, whereby said steps of generating, displaying said image, analyzing, and displaying said identification symbols are performed in real time.
Claim 11
Dependent Claim
25 words
The method defined in claim 1 wherein said step of automatically analyzing includes the step of operating a computer to identify organs in said image.
Claim 12
Independent Claim
140 words
A method for use in performing surgery, comprising the steps of: disposing a laparoscopic trocar sleeve in a skin surface of a patient; inserting at least a portion of a laparoscopic video camera device through said trocar sleeve and at least partially into the patient; upon insertion of said camera device through said trocar sleeve, operating said camera device to generate a video signal encoding video data pertaining to internal organs of the patient; displaying on a display a video image of said organs in response to said signal; automatically analyzing said signal to detect an abnormal structural condition of said organs; and while maintaining at least a substantial portion of said image on said display, displaying an identification symbol on said display, in overlap with a portion of said image, to indicate a location of the detected abnormal condition.
