Surgical stapling apparatus

摘要

A surgical stapling apparatus (10) comprising: a) a handle assembly (12) including a movable handle (24), the movable handle being movable through an actuation stroke; b) an elongated body (14) extending distally from the handle assembly and defining a longitudinal axis, the elongated body having a distal end adapted to releasably engage both articulating and non-articulating disposable loading unit types (16); c) an actuation shaft (46) supported at least in part within the handle assembly and mounted for longitudinal movement in response to manipulation of the movable handle; d) an articulation mechanism (120) including an articulation lever (30) mounted adjacent the handle assembly and an articulation link (123), the articulation link having a proximal end operatively connected to the articulation lever and a distal end positioned adjacent the distal end of the elongated body; and e) a sensing mechanism (176) positioned within the elongated body and operatively associated with the articulation mechanism, the sensing mechanism including a sensing member for sensing the type of disposable loading unit engaged with the elongated body.
