Abstract

A method of resecting a portion of lung using an electrosurgical instrument is disclosed. The electrosurgical device clamps upon lung tissue and applies RF energy to create a cauterized zone within the clamped portion of the lung. At least one staple is placed within the cauterized tissue zone. The cauterized zone is cut adjacent to the at least one staple and the cut portion of the lung is removed.

Claims

1. A method for resecting a portion of lung, said method comprising the steps of:

a) clamping said portion of lung within an end effector of an electrosurgical instrument, said end effector having an upper jaw member and a lower jaw member being sufficiently stiff in order to provide pressure to said clamped portion of lung, said upper jaw member and said lower jaw member being spaced apart by said clamped portion of said lung when said end effector is clamped onto said portion of lung;

b) applying bipolar RF energy to said clamped portion of said lung to create a cauterized zone within said clamped portion of said lung;

c) stapling said cauterized zone with at least one staple;

d) cutting said cauterized zone adjacent to said at least one staple; and

e) removing said portion of said lung.

2. The method of claim 1, wherein said cauterized zone is stapled with at least one row of staples.

3. A method for resecting a portion of lung, said method comprising the steps of:

a) clamping said portion of lung within an end effector of an electrosurgical instrument, said end effector having an upper jaw member and a lower jaw member being sufficiently stiff in order to provide pressure to said clamped portion of lung, said upper jaw member and said lower jaw member being spaced apart by said clamped portion of said lung when said end effector is clamped onto said portion of lung;

b) applying bipolar RF energy to said clamped portion of said lung to create a cauterized zone in said clamped portion of said lung;

c) stapling said cauterized zone with at least one staple;

d) stapling said clamped portion of lung adjacent to said cauterized zone with at least another staple;

e) cutting said portion of lung within said cauterized zone adjacent to said at least one staple; and

f) removing said portion of said lung.

4. The method of claim 3, wherein said cauterized zone is stapled with at least one row of staples.

5. The method of claim 4, wherein said clamped portion of lung is stapled with at least another row of staples.

6. A method for resecting a portion of lung, said method comprising the steps of:

a) clamping said portion of lung with an end effector of an electrosurgical instrument, said end effector having an upper jaw member and a lower jaw member being sufficiently stiff in order to provide pressure to said clamped portion of lung, said upper jaw member and said lower jaw member being spaced apart by said clamped portion of said lung when said end effector is clamped onto said portion of lung;

b) applying bipolar RF energy to said clamped portion of said lung to create a cauterized zone in said clamped portion of said lung;

c) stapling said clamped portion of lung outside of said cauterized zone with at least one staple;

d) cutting said portion of lung within said cauterized zone; and

e) removing said portion of said lung.

7. The method of claim 6, wherein said clamped portion of lung is stapled with at least one row of staples.

8. A method for resecting a portion of lung, said method comprising the steps of:

a) clamping said portion of lung within an end effector of an electrosurgical instrument, said end effector having an upper jaw member and a lower jaw member being sufficiently stiff in order to provide pressure to said clamped portion of lung, said upper jaw member and said lower jaw member being spaced apart by said clamped portion of said lung when said end effector is clamped onto said portion of lung;

b) stapling said clamped portion of lung with at least one staple;

c) applying bipolar RF energy to said clamped portion of said lung to create a cauterized zone adjacent to said at least one staple;

d) cutting said portion of lung within said cauterized zone; and

f) removing said portion of said lung.

9. The method of claim 8, wherein said clamped portion of lung is stapled with at least one row of staples.

11. The method of claim 9, wherein said cauterized zone is stapled with at least one row of staples.

10. A method for resecting a portion of lung, said method comprising the steps of:

a) clamping said portion of lung with an end effector of an electrosurgical instrument, said end effector having an upper jaw member and a lower jaw member being sufficiently stiff in order to provide pressure to said clamped portion of lung, said upper jaw member and said lower jaw member being spaced apart by said clamped portion of said lung when said end effector is clamped onto said portion of lung;

b) applying bipolar RF energy to said clamped portion of said lung to create a cauterized zone in said clamped portion of said lung;

c) stapling said cauterized zone with at least one staple;

d) removing said end effector from said portion of lung;

e) cutting said cauterized zone adjacent to said at least one staple with a separate cutting instrument; and

f) removing said portion of said lung.

12. The method of claim 10, wherein said cutting instrument is a pair of surgical scissors.
