Zusammenfassung:A trocar assembly for releasable engagement with an adapter assembly of a surgical stapling instrument includes housing, a trocar member slidably supported within the housing between a retracted position and an advanced position, and a chive member rotatably supported within the housing and in operable engagement with the trocar member to cause longitudinal movement of the trocar member relative to the housing between an advanced position and a retracted position. The housing includes a tubular body having a distal portion and an end cap assembly secured to the distal portion. The trocar member includes a proximal portion and at least one tab disposed on the proximal portion. The at least one tab is configured to engage the end cap assembly when the trocar member is in the advanced position to prevent further advancement of the trocar member.
