In accordance with the present invention there is provided a surgical fastening instrument. The instrument includes a handle and a shaft extending from the handle. The shaft contains a plurality of surgical fasteners therein. The instrument also has a mechanism for first distally deploying a penetrating member from the distal end of the shaft and thereafter feeding at least one of the surgical fasteners distally from the penetrating member. The instrument further includes a lockout mechanism for preventing the penetrating member from deploying from the shaft upon feeding all of the plurality of surgical fasteners from the shaft.
1. A surgical fastening instrument comprising:a. a handle;b. a shaft extending from the handle and containing a plurality of surgical fasteners therein;c. a penetrating member separate and distinct from said surgical fasteners for penetrating tissue, and a mechanism for first distally deploying said
1. A surgical fastening instrument comprising:a. a handle;b. a shaft extending from the handle and containing a plurality of surgical fasteners therein;c. a penetrating member separate and distinct from said surgical fasteners for penetrating tissue, and a mechanism for first distally deploying said penetrating member from said distal end of said shaft and thereafter feeding at least one of said surgical fasteners distally from said penetrating member;d. a means for preventing said penetrating member from deploying from said shaft upon feeding all of said plurality of surgical fasteners from said shaft;e. a trigger pivotally extending from said handle, said trigger operably coupled to said mechanism and actuatable from a first position to a second position and back to the first position to feed a surgical fastener from said shaft for each actuation of said trigger; andf. wherein said means for preventing said penetrating member from deploying from said shaft upon feeding all of said plurality of surgical fasteners from said shaft comprises a wheel which incrementally rotates in a first direction with each actuation of said trigger, and locks said trigger when all of said fasteners are delivered. 2. The surgical fastener instrument of claim 1 wherein said wheel has a plurality of ratchet teeth extending outwardly around a rim of said wheel. 3. The surgical fastener instrument of claim 2 wherein said trigger further includes a lockout arm contacting said rim of said wheel, wherein upon each actuation of said trigger brings said lockout arm into contacts with a successive tooth of said lockout wheel. 4. The surgical fastener instrument of claim 1 further including a means for preventing rotation of said locking wheel in a direction opposite to the first direction. 5. The surgical fastener instrument of claim 2 wherein the number of teeth on said locking wheel is the same as the number of fasteners within the instrument. 6. The surgical fastener instrument of claim 4 wherein one of said ratchet teeth has a locking tab extending therefrom for locking said lockout arm and said trigger in said triggers second position when said last surgical fastener is fed from said shaft. 7. A surgical fastening instrument comprising:a. a handle;b. a shaft extending from the handle and containing a plurality of surgical fasteners therein;c. a penetrating member separate and distinct from said surgical fasteners for penetrating tissue, and a mechanism for first distally deploying said penetrating member from said distal end of said shaft and thereafter feeding at least one of said surgical fasteners distally from said penetrating member;d. a lockout mechanism for preventing said penetrating member from deploying from said shaft upon feeding all of said plurality of surgical fasteners from said shaft;e. a trigger pivotally extending from said handle, said trigger operably coupled to said mechanism and actuatable from a first position to a second position and back to the first position to feed a surgical fastener from said shaft for each actuation of said trigger; andf. wherein said a lockout mechanism includes a wheel which incrementally rotates in a first direction with each actuation of said trigger, and locks said trigger when all of said fasteners are delivered. 8. The surgical fastener instrument of claim 7 wherein said wheel has a plurality of ratchet teeth extending outwardly around a rim of said wheel. 9. The surgical fastener instrument of claim 8 wherein said trigger further includes a lockout arm contacting said rim of said wheel, wherein upon each actuation of said trigger brings said lockout arm into contacts with a successive tooth of said lockout wheel. 10. The surgical fastener instrument of claim 8 further including a means for preventing rotation of said locking wheel in a direction opposite to the first direction. 11. The surgical fastener instrument of claim 8 wherein the number of teeth on said locking wheel is the same as the n umber of fasteners within the instrument. 12. The surgical fastener instrument of claim 9 wherein one of said ratchet teeth has a locking tab extending therefrom for locking said lockout arm and said trigger in said triggers second position when said last surgical fastener is fed from said shaft.
