Abstract
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.
Claims12
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;
- and
- f. 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.
