16. An electrosurgical debridement device, comprising:
an outer shaft defining a window;
an inner shaft disposed within the outer shaft;
a clip housing defining a window and configured to receive a proximal end portion of the inner shaft;
at least one electrode disposed on the inner shaft and having a proximal end portion removably connected to a clip disposed within the clip housing and a distal end portion configured to be exposed through the window defined by the outer shaft, wherein at least a portion of the clip is exposed through the window defined by the clip housing; and
an actuator coupled to the exposed portion of the clip, wherein movement of the actuator to an activation position is configured to complete an electrical pathway between the clip and a power source such that power is delivered from the power source to the at least one electrode.
