Surgical instrument having a bipolar end effector assembly and a deployable monopolar assembly

A surgical instrument, comprising:

• a housing;
• first, second, and third actuators operably coupled to the housing;
• a shaft extending distally from the housing, at least a portion of the shaft defining a semi-rigid configuration enabling the shaft to be bent at an angle of up to 35 degrees without permanent deformation or breaking;
• a rotation assembly positioned in the housing, the rotation assembly including an engagement ferrule positioned about a proximal portion of the shaft, the engagement ferrule including a recess formed at least partially around the engagement ferrule;
• an engagement clip engaged with an outer surface of the engagement ferrule in the recess, the engagement clip including at least one protrusion configured to fix the proximal portion of the shaft to the engagement ferrule;
• an end effector assembly disposed at a distal end of the shaft;
• and
• first, second, and third bars extending through the shaft and disposed in non-coaxial arrangement relative to each other and the shaft, the first bar operably coupled between the first actuator and the end effector assembly such that actuation of the first actuator effects manipulation of the end effector assembly, the second bar operably coupled between the second actuator and a first deployable component such that actuation of the second actuator effects deployment of the first deployable component relative to the end effector assembly, the third bar operably coupled between the third actuator and a second deployable component such that actuation of the third actuator effects deployment of the second deployable component relative to the end effector assembly,
• wherein the first, second, and third actuators are actuatable to manipulate the end effector assembly, deploy the first deployable component, and deploy the second deployable component, respectively, with the shaft bent at an angle of up to 35 degrees from a longitudinal axis thereof.
