Abstract
A surgical instrument includes an articulation joint and end effector extending distally from the articulation joint, wherein the end effector comprises a drive pin movable between a first position and a second position. Furthermore, the surgical instrument includes a shaft extending proximally from the articulation joint, and an articulation driver configured to move the drive pin from the first position to the second position to transition the end effector from an unarticulated configuration to an articulated configuration. Also, the surgical instrument includes a pin slot extending from the articulation driver, wherein the pin slot is configured to movably accommodate the drive pin in the unarticulated configuration, and wherein the pin slot is configured to tightly accommodate the drive pin in the articulated configuration.
