摘要：
A stapling head assembly of a suturing and cutting apparatus for endoscopic surgery includes a cartridge, a cartridge support detachably connected to the cartridge, an actuating block including an unlocking component set movably in the cartridge, a cutter, and a lockout mechanism. The cutter is adapted to move longitudinally along the cartridge, between a first position and a second position. The mechanism includes a lockout block set in said cartridge support and transversely movable with respect to the support between third and fourth positions, and a flexible component set between the support and the lockout block and actuating the lockout block to move from the third to the fourth positions. When the flexible component is under compression, the cutter can move from the first to the second positions. After the actuating block is actuated, the lockout block moves to the fourth position under action of the flexible component.
