Abstract
A surgical instrument is disclosed. The surgical instrument may be operated compensating for the effect of splay in flexible knife bands on transection length of a powered surgical instrument. The surgical instrument includes a processor and a memory. A relationship between articulation angle of an end effector and effective transection length distal of an articulation joint is characterized. The characterization data is accessed by the processor from the memory of the surgical instrument. The articulation angle of the end effector is tracked by the processor during use of the surgical instrument. The target transection length is adjusted by the processor based on the known articulation angle and the stored characterization data.
