Methods and Devices for Locking a Surgical Device Based on Loading of a Fastener Cartridge in the Surgical Device

摘要

Devices and methods are provided for locking a surgical device based on loading of a fastener cartridge in the surgical device. In general, a surgical device can be configured to prevent at least one of closure of an end effector of the surgical device and firing of fasteners from the end effector when a cartridge is not fully seated in the end effector. In an exemplary embodiment, the surgical device can include a lockout element configured to prevent at least one of closure of the end effector and firing of fasteners from the end effector when a cartridge is not fully seated in the end effector. The locking element can be configured to automatically prevent firing and/or prevent closing of the end effector if a cartridge is not fully seated in the end effector.
