Abstract

A method includes providing a graphical representation of a surgical site, grasping the tissue of the patient with first and second jaw members of an end effector including a location sensor, illuminating optical light into the grasped tissue at the first jaw member, receiving the optical light that has passed through the grasped tissue, at the second jaw member, processing the received light to identify a vessel, which is encompassed within the grasped tissue, receiving location information of the end effector from the location sensor, synchronizing a location of the identified vessel within the graphical representation based on the location information, and displaying the identified vessel at the synchronized location in the graphical representation.

First claim

What is claimed is:

1. A method for identifying a vessel within tissue, the method comprising:
providing a graphical representation of a surgical site;
grasping the tissue of the patient with first and second jaw members of an end effector including a location sensor;
illuminating optical light into the grasped tissue via an optical light source disposed on the first jaw member;
receiving, at a light sensor disposed on the second jaw member, the optical light that has passed through the grasped tissue;
processing the received light to identify a vessel, which is encompassed within the grasped tissue;
receiving location information of the end effector from the location sensor;
synchronizing a location of the identified vessel within the graphical representation based on the location information; and
displaying the identified vessel at the synchronized location in the graphical representation.

2. The method of claim 1 , further comprising:
supplying energy to the tissue through the end effector to seal the identified vessel;
illuminating the optical light into the identified vessel after supplying the energy; and
receiving the optical light that has passed through the identified vessel.

3. The method of claim 2 , further comprising:
processing the received optical light during or after supplying the energy.

4. The method of claim 3 , further comprising:
confirming whether or not the identified vessel is sealed.

5. The method of claim 4 , wherein the identified vessel is confirmed to be sealed by comparing the identified vessel before supplying the energy with the identified vessel after supplying the energy.

6. The method of claim 1 , wherein the graphical representation is a 3D model or a video image.

7. The method of claim 1 , wherein the vessel is selected from the group consisting of a bile vessel, a lymph vessel, and a blood vessel.

8. The method of claim 1 , further comprising:
generating an electromagnetic wave.

9. The method of claim 8 , further comprising:
sensing the electromagnetic wave, wherein the location information is based on the sensed electromagnetic wave.

10. The method of claim 9 , wherein the identified vessel is displayed in an augmented manner in the graphical representation.

11. A method for identifying a vessel within tissue, the method comprising:
receiving, at a light sensor disposed on a first jaw member of an end effector, optical light illuminated by an optical light source disposed on a second jaw member of the end effector and that has passed through tissue grasped between the first and second jaw members;
processing the received light to identify a vessel, which is encompassed within the grasped tissue;
receiving location information of the end effector from a location sensor disposed on the end effector;
synchronizing a location of the identified vessel within a graphical representation of a surgical site based on the location information; and
displaying the identified vessel at the synchronized location in the graphical representation.
