1. A method for obviating spline crash in a surgical stapler utilizing a motor of the surgical stapler, the method comprising:
during approximation of an anvil assembly of the surgical stapler and a shell assembly of the surgical stapler, a processing unit detecting an impact of an anvil spline of the anvil assembly with a shell spline of the shell assembly of the surgical stapler;
then, oscillating an anvil retainer of the surgical stapler in a longitudinal direction between extension and retraction with the motor such that an anvil of the surgical stapler moves towards and away from the shell assembly of the surgical stapler in a first oscillation pattern;
oscillating the anvil retainer in the longitudinal direction between extension and retraction such that the anvil moves towards and away from the shell assembly in a second oscillation pattern after the first oscillation pattern; and
retracting the anvil retainer until the anvil is in a clamped position relative to the shell assembly after the second oscillation pattern.
