System and method of using simulation reload to optimize staple formation
The present disclosure is directed to a testing systems and methods for testing a powered surgical instrument. The powered surgical instrument includes a processor configured to control operation of the powered surgical instrument, a memory configured to store a tissue compression program, a reload configured to clamp tissue, a motor configured to control the reload to apply a compressive force to the tissue by the reload, and at least one sensor configured to measure a current draw on the motor. The processor executes the simulation program to measure the current draw on the motor through a nominal thickness firing and the measured current draw is used to adjust the tissue compression program.
1. A simulation system comprising:
a powered surgical instrument including:
a first processor configured to control operation of the powered surgical instrument;
a first memory configured to store a tissue compression program; and
a motor configured to control a reload to apply a compressive force to the tissue by the reload;
a simulation reload including:
a second memory configured to store a simulation program; and
a second processor configured to execute the simulation program,
wherein the second processor executes the simulation program to measure a current draw on the motor through a nominal thickness firing and wherein the measured current draw is stored in the second memory; and
a test platform including:
a first interface configured to be operatively connected to the powered surgical instrument; and
a second interface configured to be operatively connected to the simulation reload;
wherein the test platform is configured to adjust the tissue compression program stored in the first memory based on the measured current draw stored in the second memory.
2. The powered surgical instrument of claim 1 , wherein the tissue compression program includes programming code coefficients, and wherein the test platform adjusts the programming code coefficients based on the measured current draw.
3. The powered surgical instrument of claim 2 , wherein the test platform compares the measured current draw to a predetermined current draw associated with the nominal thickness firing.
4. The powered surgical instrument of claim 3 , wherein the difference between the measured current draw and the predetermined current draw is used to adjust the programming code coefficients.
