SURGICAL STAPLER WITH ANVIL STATE INDICATOR

摘要

A surgical instrument includes a stapling head assembly, an anvil, an anvil adjustment assembly, and an indicator assembly. The anvil is configured to couple with the stapling head assembly. The anvil adjustment assembly includes a translating member, which is operable to translate relative to the body to thereby adjust a gap distance between the anvil and a distal surface of the stapling head assembly. The indicator assembly includes a first member and a second member. The first member is configured to translate in response to translation of the translating member relative to the body. The second member is configured to remain stationary relative to the body. The indicator assembly is configured to provide feedback indicating whether the gap distance is sized to release tissue from between the anvil and the distal surface based on positioning of the first member in relation to the second member.
