SURGICAL INSTRUMENT AND BUSHING A surgical instrument (10) comprising a handle assembly (20), and actuation member (22), an elongated body portion (30), and a locking mechanism (400) is disclosed. The locking mechanism (400) is disposed in mechanical cooperation with the actuation member (22) , and is configured to substantially prevent at least a partial movement of the actuation member (22) when the elongated body portion (30) is not engaged with a loading unit (500). The locking mechanism (400) comprises a link (402), a bushing (460), and a connecting member (406). The link (402) is configured for mechanical engagement with a portion of a loading unit (500). At least a portion of the bushing (460) is disposed proximally of at least a portion of the link (402). At least a portion of the connecting member (406) is disposed proximally of at least a portion of the bushing (460). Engagement between a loading unit (500) and the elongated body portion (30) causes proximal movement of the link (402), the bushing (460), and the connecting member (406). / >8 Lfl U, |
