More Information
Summary:A powered surgical instrument (10; 100; 1000) comprising: a processor (202) configured to control operation of the powered surgical instrument and to place the powered surgical instrument in a simulation state; a memory (208) configured to store a tissue compression program that includes programming code coefficients; a reload (500; 3000), comprising a tool assembly (504; 3040), releasably attached to the distal end of the powered surgical instrument and configured to clamp tissue; a motor (212) configured to control the reload to apply a compressive force to the tissue by the reload; and at least one sensor (214) configured to measure a current draw on the motor, wherein, when the powered surgical instrument is placed in a reload simulation state to test the powered surgical instrument, the processor is operable to execute a simulation program stored in the memory to measure the current draw on the motor during the simulation state when the powered surgical instrument simulates a staple firing through a predetermined nominal thickness; and wherein the processor adjusts the programming code coefficients of the tissue compression program based on the measured current draw on the motor during the simulation state.
