1. An electrosurgical forceps, comprising:
a housing having a shaft extending distally therefrom, the shaft defining a longitudinal axis therethrough; a knife blade shaft operably positioned within the shaft; an end effector operably disposed at a distal end of the shaft, the end effector including a pair of spaced-apart first and second jaw members movable from an open configuration to a clamping configuration; and an electrode assembly including first and second electrode housings and a knife blade, the first and second electrode housings operably coupled to one another and configured to selectively couple to respective first and second jaw members to electrosurgically treat tissue clamped between the first and second jaw members, the knife blade configured to selectively couple to the knife blade shaft such that rotation of the knife blade shaft relative to the shaft decouples the knife blade shaft from the knife blade, wherein a distal end of the knife blade shaft includes a mechanical interface configured to releasably couple to a corresponding mechanical interface disposed at a proximal end of the knife blade, the at least one mechanical interface on the knife blade in the form of a notch and the corresponding mechanical interface on the knife blade shaft in the form of a boss having a shape that complements the notch, the knife blade shaft rotatable about the longitudinal axis and relative to the knife blade to allow the boss to engage the notch of the knife blade. |
