    摘要： A surgical stapling instrument (10) includes anvil and cartridge portions (100, 200) operably coupled together. The anvil and cartridge portions (100, 200) are transitionable between clamped and unclamped configurations. The surgical stapling instrument (10) also includes a clamp detection assembly (300) with a plunger (312) slidably disposed in a chamber (310) of a housing (302), a block (314) with an aperture (316) attached to the plunger (312), a spring (318) disposed in the chamber (310), and a button (340) slidably disposed in a recess (180) of the anvil portion (100). The spring (318) biases the plunger (312) and block (314) towards the cartridge portion (200) such that the aperture (316) is out of alignment with the button (340) in the unclamped configuration and engagement of the plunger (312) with a bridge (254) of the cartridge portion (200) translates the plunger (312) and the block (314) away from the opening of the chamber (310) such that the aperture (316) is aligned with the button (340) in the clamped configuration.

    摘要： A surgical stapling device includes a clamp slide assembly and an end effector that includes a cartridge module. The clamp slide assembly includes a distal portion that defines a curved slot and includes a linear section that defines linear channels. The cartridge module includes a curved module body that includes a linear section that includes linear ribs. The linear ribs are received within the linear channels to facilitate loading of the cartridge module into the distal portion of the clamp slide assembly in a linear fashion.

    摘要： Locking assemblies for surgical clamping and cutting instruments include a locking member and a switch. A drive member may be configured to releasably engage a knife and/or a shuttle of the surgical instrument for translating the knife and/or shuttle in a distal direction through a firing stroke. The locking member is movable from a first position permitting distal translation of the drive member through the firing stroke, and a second position inhibiting distal translation of the drive member through the firing stroke. A switch, when proximally positioned, releasably engages the locking member to maintain the locking member in the first position. The switch disengages from the locking member when the switch is moved to a distal position.
