Surgical instrument and bushing

A surgical instrument, comprising:

• a handle assembly;
• an actuation member disposed in mechanical cooperation with the handle assembly;
• an elongated body portion extending distally from the handle assembly and defining a longitudinal axis;
• a loading unit including a proximal body portion and a tool assembly, the proximal body portion configured for selective engagement with the elongated body portion;
• and
• a locking mechanism disposed in mechanical cooperation with the actuation member, the locking mechanism configured to enable movement of the actuation member when the elongated body portion and the loading unit are engaged, the locking mechanism including:
• a link disposed at least partially within the elongated body portion and configured for mechanical engagement with a portion of the loading unit, at least a portion of the link being longitudinally translatable with respect to the elongated body portion;
• a bushing, at least a portion of the busing disposed proximally of at least a portion of the link, at least a portion of the bushing being longitudinally translatable with respect to the elongated body portion, the bushing including a body portion and finger extending distally from the body portion, the finger including a tongue configured to engage an engagement structure of the link;
• and
• a connecting member, at least a portion of the connecting member disposed proximally of at least a portion of the bushing, the connecting member being disposed in mechanical cooperation with the actuation member;
• wherein engagement between the loading unit and the elongated body portion causes proximal movement of the link, proximal movement of the bushing, and proximal movement of the connecting member.
