A surgical stapler having a supporting frame, replaceable staple cartridge, an anvil, a mechanism for approximating the cartridge relative to the anvil, and a mechanism for firing the device so as to crimp the staples against the anvil in a manner to enable the surgeon to substantially simultaneously place one or more rows of surgical staples in organs or tissue. The device, while at all times permitting approximation of the cartridge relative to the anvil, provides a novel lockout feature for positively preventing retiring if the staple cartridge is spent. In this way, unlike the prior art devices, the device of the present invention can be used as a clamping mechanism even after the staples have been fired.

[ We claim:] [1.] An apparatus for simultaneously securing a plurality of surgical staples in tissue comprising:a supporting frame;a staple cartridge containing a plurality of staples receivable into said frame;an anvil mounted on said supporting frame for engagement by said staples;approximation means for moving said staple cartridge within said supporting frame from a retracted position to a clamping position proximate said anvil;a pusher member positioned at least partially within said staple cartridge and movable relative thereto into driving engagement with said staples;an operating member movable within said supporting frame for advancement of said pusher member relative to said staples so as to drive said staples into engagement with said anvil; andlocking means for releasably locking said operating member against movement relative to said supporting frame, said locking means including a locking element connected to said approximation means and having a locking protuberance for engaging said approximation means, said locking protuberance moveable from a first position relative to said operating member to a second position, wherein said locking element blocks movement of said operating member toward said staple cartridge.
