A surgical instrument 10 comprising a handle assembly 20, and actuation member, an elongated body portion 30, and a locking mechanism 400 is disclosed. The locking mechanism is disposed in mechanical cooperation with the actuation member, and is configured to substantially prevent at least a partial movement of the actuation member when the elongated body portion is not engaged with a loading unit 500. The locking mechanism comprises a link 402, a bushing 460, and a connecting member 406. The link is configured for mechanical engagement with a portion of a loading unit. At least a portion of the bushing is disposed proximally of at least a portion of the link. At least a portion of the connecting member is disposed proximally of at least a portion of the bushing. Engagement between a loading unit and the elongated body portion causes proximal movement of the link, the bushing, and the connecting member. |
