摘要： A surgical instrument comprises a body, shaft, and end effector. The shaft couples the end effector and body together. The end effector comprises an anvil and lower jaw configured to receive a surgical staple cartridge. The anvil is configured to pivot toward and away from the staple cartridge and lower jaw. The shaft assembly comprises a knife member configured to longitudinally translate to thereby substantially simultaneously cut clamped tissue and staple the severed tissue. The end effector may comprise lockout features configure to prevent longitudinal translation of the knife member. The end effector or staple cartridge may comprise lockout bypass features configured to prevent lockout of the knife member.

摘要： A surgical circular stapler has a handle assembly, a shaft, a stapling assembly, a motor, a drive assembly, and a firing assembly. The shaft extends distally from the handle assembly. The stapling assembly is secured to a distal end of the shaft. Longitudinal translation of the firing assembly causes the stapling assembly to drive a plurality of staples in a circular array to secure two lumens of tissue together. The stapling assembly may further drive a blade to sever any excess tissue interior of the circular array of staples. The motor is operable to rotate the drive assembly to thereby translate the firing assembly. A resilient member biases the firing assembly proximally. Through cooperation between the firing assembly and the resilient member, the firing assembly is driven distally and proximally to complete a firing stroke in response to rotation of the drive assembly through a single revolution. A cam assembly is coupled to the motor and to the firing assembly. The motor rotates the cam assembly to drive the firing assembly with a varying longitudinal force.
摘要翻译：外科圆形订书机具有手柄组件，轴，钉书钉组件，马达，驱动组件和发射组件。轴从手柄组件向远侧延伸。装订组件固定到轴的远端。射击组件的纵向平移导致缝合组件以圆形阵列驱动多个钉，以将两个组织的组织固定在一起。缝合组件可以进一步驱动刀片以切断圆形排列的钉的任何多余的组织内部。马达可操作以使驱动组件旋转，从而平移击发组件。弹性构件向近侧偏压击发组件。通过射击组件和弹性构件之间的协作，射击组件被向远侧和近侧驱动，以响应于驱动组件通过单次旋转的旋转来完成击发冲程。凸轮组件联接到电动机和发射组件。马达使凸轮组件旋转以以变化的纵向力驱动击发组件。
