Classification: CPC A | IPC A

Claim 14:
15. A method comprising:
applying a force to tissue using an end effector of a surgical instrument;
measuring, by a processor, the force applied to the tissue;
comparing, by the processor, the measured force to a threshold minimum force value;
measuring, by the processor, a value of power by the end effector when the end effector applies the force to the tissue;
computing, by the processor, a coefficient of determination value using the value of power and the measured force;
determining, by the processor, a coefficient of friction of the tissue using the coefficient of determination value;
determining, by the processor, a type of tissue by comparing the determined coefficient of friction to a database relating stored coefficients of friction to predetermined types of tissue; and
selecting, by the processor, a power delivery profile for delivering energy from a generator to the end effector that is suitable for performing a surgical operation on the determined type of tissue; and
delivering the energy having the selected power delivery profile from the generator to perform the surgical operation on the determined type of tissue.
