Abstract

A method of surgery includes inserting a surgical instrument into a surgical site, supplying energy from a surgical generator to tissue at the surgical site via the surgical instrument to treat the tissue, sensing at least one property of smoke at the surgical site, and determining at least one parameter of smoke at the surgical site based upon the at least one property. The method further includes controlling the supply of energy from the surgical generator based upon the at least one parameter and/or providing an output based upon the at least one parameter.

First claim

What is claimed is:

1 . A method of surgery, comprising:
inserting a surgical instrument into a surgical site; supplying energy from a surgical generator to tissue at the surgical site via the surgical instrument to treat the tissue; sensing at least one property of smoke at the surgical site; determining at least one parameter of smoke at the surgical site based upon the at least one property; and controlling the supply of energy from the surgical generator based upon the at least one parameter.

2 . The method according to claim 1 , wherein sensing the at least one property includes sensing an optical property, a chemical property, an electrical property, or a smell-based property.

3 . The method according to claim 1 , wherein determining the at least one parameter includes determining presence of smoke, presence of a type of smoke particle, an amount of smoke particles, or a ratio of smoke to steam.

4 . The method according to claim 1 , wherein determining the at least one parameter includes determining temperature of smoke, density of smoke, or color of smoke.

5 . The method according to claim 1 , wherein the sensing is performed by a device separate from the surgical instrument.

6 . The method according to claim 1 , wherein controlling the supply of energy includes at least one of: starting, modifying, continuing, or stopping the supply of energy from the surgical generator to the surgical instrument.

7 . The method according to claim 1 , wherein the at least one parameter is determined using a machine learning algorithm.

8 . The method according to claim 1 , further comprising determining a type of the tissue being treated based upon the at least one parameter, wherein controlling the supply of energy includes controlling the supply of energy based upon the type of the tissue being treated.

9 . The method according to claim 1 , further comprising determining a state of the tissue being treated based upon the at least one parameter, and wherein controlling the supply of energy includes controlling the supply of energy based upon the state of the tissue being treated.

10 . The method according to claim 1 , further comprising determining a status of tissue treatment based upon the at least one parameter, and wherein controlling the supply of energy includes controlling the supply of energy based upon the status of tissue treatment.

11 . A method of surgery, comprising:
inserting a surgical instrument into a surgical site; supplying energy from a surgical generator to tissue at the surgical site via the surgical instrument to treat the tissue; sensing at least one property of smoke at the surgical site; determining at least one parameter of smoke at the surgical site based upon the at least one property; and providing an output based upon the at least one parameter.

12 . The method according to claim 11 , wherein sensing the at least one property includes sensing an optical property, a chemical property, an electrical property, or a smell-based property.

13 . The method according to claim 11 , wherein determining the at least one parameter includes determining presence of smoke, presence of a type of smoke particle, an amount of smoke particles, or a ratio of smoke to steam.

14 . The method according to claim 11 , wherein determining the at least one parameter includes determining temperature of smoke, density of smoke, or color of smoke.

15 . The method according to claim 11 , wherein the sensing is performed by a device separate from the surgical instrument.

16 . The method according to claim 11 , wherein providing the output includes providing at least one of an audible output, a visual output, or a tactile output.

17 . The method according to claim 11 , wherein the at least one parameter is determined using a machine learning algorithm.

18 . The method according to claim 11 , further comprising determining a type of the tissue being treated based upon the at least one parameter, and wherein providing the output includes indicating the type of the tissue being treated.

19 . The method according to claim 11 , further comprising determining a state of the tissue being treated based upon the at least one parameter, and wherein providing the output includes indicating the state of the tissue being treated.

20 . The method according to claim 11 , further comprising determining a status of tissue treatment based upon the at least one parameter, and wherein providing the output includes indicating the status of tissue treatment.
