A surgical instrument comprising a handle assembly, and actuation member, an elongated body portion, and a locking mechanism 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. The locking mechanism comprises a link, a bushing, and a connecting member. The link is configured for mechanical engagement with a portion of a loading unit. At least a portion of the busing 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.
1. 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 distal portion of the elongated body portion configured to
1. 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 distal portion of the elongated body portion configured to selectively engage a loading unit; anda locking mechanism disposed in mechanical cooperation with the actuation member, the locking mechanism 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, the locking mechanism comprising: a link disposed at least partially within the elongated body portion and configured for mechanical engagement with a portion of a 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; anda 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 a 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. 2. The surgical instrument of claim 1, wherein a distal face of the bushing abuts a proximal end of the link. 3. The surgical instrument of claim 1, wherein a proximal face of the bushing abuts a distal end of the connecting member. 4. The surgical instrument of claim 1, further comprising a control rod disposed at least partially within the elongated body portion, wherein longitudinal translation of the control rod effects a function of a loading unit when the loading unit is engaged with the elongated body portion. 5. The surgical instrument of claim 4, wherein the control rod is longitudinally translatable with respect to the link, with respect to the bushing and with respect to the connecting member. 6. The surgical instrument of claim 4, wherein the control rod is longitudinally translatable through an aperture in the bushing. 7. The surgical instrument of claim 4, wherein the control rod is longitudinally translatable through the connecting member. 8. The surgical instrument of claim 1, wherein a transverse dimension of a contacting portion of a proximal surface of the bushing is between about 2 to about 10 times larger than a distal end of a wall of the connecting tube. 9. The surgical instrument of claim 1, wherein a transverse dimension of a contacting portion of a distal surface of the bushing is between about 1 to about 6 times larger than a proximal end of the link. 10. 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; anda 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 comprising: 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; anda 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. 11. The surgical instrument of claim 10, wherein a distal face of the bushing abuts a proximal end of the link. 12. The surgical instrument of claim 10, wherein a proximal face of the bushing abuts a distal end of the connecting member. 13. The surgical instrument of claim 10, further comprising a control rod disposed at least partially within the elongated body portion, wherein longitudinal translation of the control rod effects a function of the loading unit when the loading unit is engaged with the elongated body portion. 14. The surgical instrument of claim 13, wherein the control rod is longitudinally translatable with respect to the link, with respect to the bushing and with respect to the connecting member. 15. The surgical instrument of claim 13, wherein the control rod is longitudinally translatable through an aperture in the bushing. 16. The surgical instrument of claim 13, wherein the control rod is longitudinally translatable through the connecting member. 17. The surgical instrument of claim 10, wherein a transverse dimension of a contacting portion of a proximal surface of the bushing is between about 2 to about 5 times larger than a distal end of a wall of the connecting tube. 18. The surgical instrument of claim 10, wherein a transverse dimension of a contacting portion of a distal surface of the bushing is between about 2 to about 5 times larger than a proximal end of the link.
