Method for circular stapler control algorithm adjustment based on situational awareness

A method of adjusting a cutting parameter of a circular surgical stapler, the method comprising:

• receiving, by a control circuit of the circular surgical stapler, a sensor output signal from a sensor of the circular surgical stapler during a tissue clamping motion;
• determining, by the control circuit, a tissue toughness parameter associated with clamping of an end effector of the circular surgical stapler during the tissue clamping motion, based on the sensor output signal;
• and
• controlling, by the control circuit, a torque applied to a cutting member of the circular surgical stapler, wherein a motor of the circular surgical stapler moves the cutting member between a first position and a second position by applying the torque to the cutting member, wherein the torque corresponds to a first velocity profile when the tissue toughness parameter is less than a threshold parameter, and wherein the torque corresponds to a second velocity profile when the tissue toughness parameter is greater than the threshold parameter.

A method of controlling a circular surgical stapler, the method comprising:

• receiving, by a control circuit of the circular surgical stapler, a sensor output signal from a first sensor of the circular surgical stapler;
• determining, by the control circuit, a parameter associated with operation of the circular surgical stapler, based on the sensor output signal;
• determining, by the control circuit, an anvil gap of an anvil of the circular surgical stapler, wherein the anvil clamps tissue;
• comparing, by the control circuit, the anvil gap to a predetermined gap;
• and
• executing, by the control circuit, an electronic lockout to prevent actuation of the circular surgical stapler based on the comparison and the determined parameter, wherein the electronic lockout corresponds to a compulsory lockout when the comparison falls within a first range, and wherein the electronic lockout corresponds to a discretionary lockout when the comparison falls within a second range.
