Abstract
A system for use with a surgical instrument includes an end effector, a memory circuit to store computer-executable instructions, and a processor. The end effector comprises a cutting member and a load cell sensor configured to sense a measure of force used to advance the cutting member through captured tissue. The processor is configured to execute the computer-executable instructions to initiate a first treatment cycle, access the measure of force used during the first treatment cycle to advance the cutting member through the captured tissue, determine that the measure of force exceeds a predetermined threshold, and generate an alert to a user of the surgical instrument based on the determination that a value of the measure of force exceeds the predetermined threshold. The predetermined threshold is based on an accumulation of biological material on the cutting member and a normal operational parameter of the first treatment cycle.
