More Information
Summary:A surgical instrument includes a drive housing, a spline, a carriage, an elongate shaft assembly, an end effector, and an activating mechanism. The spline includes a drive gear rotatable via the spline. The shaft assembly extends from the carriage. The activating mechanism is housed in the carriage and includes a barrel cam extending along a rotational axis. The barrel cam has a first cam profile radially extending about the rotational axis. The barrel cam is operatively coupled to the drive gear such that rotation of the drive gear is configured to actuate the activating mechanism to move at least a portion of the end effector. The first cam profile defines a first operational section, a second operational section, and an operational transition positioned between the first and second operational sections. The first and the second operational sections extend from the operational transition in opposite directions.
