Abstract
A surgical instrument is disclosed including a housing, a shaft assembly extending distally from the housing, a stapling head assembly located at a distal end of the shaft assembly, an anvil couplable with the stapling head assembly, and an anvil adjustment assembly. The stapling head assembly includes a distal surface. The stapling head assembly is operable to drive an annular array of staples through the distal surface. The stapling head assembly includes a radio-frequency identification (RFID) scanner. The anvil is translatable relative to the stapling head assembly toward a closed configuration and the anvil includes an RFID tag. The anvil adjustment assembly includes a translating member operable to translate relative to the housing along a longitudinal axis to thereby adjust a longitudinal position of the anvil relative to the distal surface. The RFID tag is detectable by the RFID scanner at or below an attachment threshold distance.
