摘要：
A surgical stapling apparatus, comprising: a first jaw member (508) having a channel； a second jaw member having an anvil with staple depressions； a cartridge (512) configured to selectively engage the first jaw member (508), the cartridge has fasteners and a pulse assembly, the pulse assembly includes a slide (515) that interacts with a plurality of pushers to drive fasteners out of the cartridge； a pulse member (505) movable through the channel from a retracted position to an advanced one, said pulse member is configured to push the slide (515), whereby the slide drives the pushers (517b, 518) and the pushers they push the fasteners (517a) towards the anvil as the impulse member advances； and a lock assembly (530) configured to lock the impulse member (505) to prevent a bad firing thereof when there is no cartridge (512) coupled to the first jaw member (508) or when a spent cartridge is attached to the first jaw member (508), characterized in that: said locking assembly comprises a locking lever (540) rotatably mounted on the first jaw member (508) and predisposed towards the channel and to the locked position； and said surgical stapling apparatus further comprises an actuator (532) in the cartridge (512) coupled to the slider (515), the actuator is configured to rotate the locking lever (540) from the channel away from the locked position when the cartridge is coupled to the first jaw member (508), the actuator is predisposed against one of said pushers (518), whereby the movement of said one of said pushers (518) by the slider (515) as advance the impulse member releases the locking lever.Un aparato de grapado quirúrgico, que comprende: un primer miembro de mordaza (508) que tiene un canal； un segundo miembro de mordaza que tiene un yunque con depresiones de formación de grapas； un cartucho (512) configurado para acoplarse selectivamente al primer miembro de mordaza (508), el cartucho tiene sujetadores y un conjunto de impulso, el conjunto de impulso incluye una
