Abstract

A surgical system for use in a surgical procedure is disclosed. The surgical system includes a surgical visualization system and a control circuit configured to propose a portion of an organ to resect based on visualization data from the surgical visualization system, determine a first value of a non-visualization parameter of the organ prior to resection of the portion, and determine a second value of the non-visualization parameter of the organ after resection of the portion. Resection of the portion is configured to yield an estimated capacity reduction of the organ.

First claim

What is claimed is:

1. A surgical system for use in a surgical procedure, the surgical system comprising:
a surgical visualization system; and
a control circuit, configured to:
propose a portion of an organ to resect based on visualization data from the surgical visualization system, wherein resection of the portion is configured to yield an estimated capacity reduction of the organ;
propose a resection path based on the portion of the organ to resect and the visualization data;
determine a first value of a non-visualization parameter of the organ prior to resection of the portion; and
determine a second value of the non-visualization parameter of the organ after resection of the portion.

2. The surgical system of claim 1 , wherein the non-visualization parameter comprises a peak lung volume measured by a ventilator.

3. The surgical system of claim 1 , wherein the non-visualization parameter comprises PCO 2 measured by a ventilator.

4. The surgical system of claim 1 , wherein the control circuit is further configured to corroborate the estimated capacity reduction based on the first value of the non-visualization parameter and the second value of the non-visualization parameter.

5. The surgical system of claim 4 , wherein the estimated capacity reduction is equal to or less than a predetermined threshold.

6. The surgical system of claim 1 , wherein the organ comprises a lung.

7. The surgical system of claim 6 , wherein the control circuit is further configured to detect an air leak in the lung after the resection of the portion.

8. The surgical system of claim 7 , wherein the air leak is detected using dynamic visualization data of the lung from the surgical visualization system after the resection.

9. A surgical system for use in a surgical procedure, the surgical system comprising:
a surgical visualization system; and
a control circuit, configured to:
receive an input from a user indicative of a portion of an organ to resect;
estimate a capacity reduction of the organ from removing the portion based on visualization data from the surgical visualization system; and
propose a resection path based on the visualization data from the surgical visualization system and the input from the user.

10. The surgical system of claim 9 , wherein the control circuit is further configured to determine a first value of a non-visualization parameter of the organ prior to resection of the portion.

11. The surgical system of claim 10 , wherein the control circuit is further configured to determine a second value of the non-visualization parameter of the organ after resection of the portion.

12. The surgical system of claim 11 , wherein the control circuit is further configured to corroborate the estimated capacity reduction of the organ based on the first value of the non-visualization parameter and the second value of the non-visualization parameter.

13. The surgical system of claim 12 , wherein the non-visualization parameter comprises peak lung volume measured by a ventilator.

14. The surgical system of claim 12 , wherein the non-visualization parameter comprises PCO 2 measured by a ventilator.

15. The surgical system of claim 12 , wherein the organ comprises a lung.

16. The surgical system of claim 15 , wherein the control circuit is further configured to detect an air leak in the lung after the resection using dynamic visualization data of the lung from the surgical visualization system.

17. A surgical system for use in a surgical procedure, the surgical system comprising:
a surgical visualization system; and
a control circuit, configured to:
receive, during a surgical procedure, first visualization data from the surgical visualization system in a first state of an organ;
determine, during the surgical procedure, a first value of a non-visualization parameter of the organ in the first state;
receive, during the surgical procedure, second visualization data from the surgical visualization system in a second state of the organ;
determine, during the surgical procedure, a second value of the non-visualization parameter of the organ in the second state; and
detect, during the surgical procedure, a tissue abnormality based on the first visualization data, the second visualization data, the first value of the non-visualization parameter, and the second value of the non-visualization parameter.

18. The surgical system of claim 17 , wherein the non-visualization parameter comprises lung pressure measured by a ventilator.

19. The surgical system of claim 17 , wherein the non-visualization parameter comprises lung volume measured by a ventilator.

20. The surgical system of claim 17 , wherein the first visualization data and the second visualization data comprises surface geometry measurements by the surgical visualization system.

21. The surgical system of claim 17 , wherein the organ comprises a lung, wherein the first state comprises the lung in an inflated state, and wherein the second state comprises the lung in a deflated state.
