A recently granted patent (Publication Number: US11903634B2) discloses a method involving the application of force to tissue using a surgical instrument's end effector. The method includes measuring the force applied, comparing it to a minimum threshold value, determining the type of tissue based on the coefficient of friction calculated using power values, and selecting a suitable power delivery profile for performing a surgical operation on the identified tissue type. The processor dynamically adjusts the power delivery profile based on changes in the tissue's coefficient of friction, enhancing the accuracy of the procedure.

Furthermore, the method involves a learning mode to improve the accuracy of determining the tissue's coefficient of friction. By applying various forces to the tissue and measuring corresponding power values, the processor computes slope values and coefficients of determination to identify the best fit slope value with the highest coefficient of determination. This approach ensures precise determination of the tissue's coefficient of friction, enabling the selection of an optimal power delivery profile for effective surgical operations. The patent emphasizes the importance of adapting the power delivery profile based on real-time changes in the tissue's properties, highlighting the innovative and adaptive nature of the surgical method outlined in the patent.
