Abstract
An electrosurgical instrument comprising a housing, a shaft extending from the housing, an end effector extending from the shaft, an articulation joint rotatably connecting the end effector to the shaft, and a wiring circuit is disclosed. The housing comprises a printed control board. The wiring circuit extends from the printed control board through the shaft and into the end effector. The wiring circuit is configured to monitor a function of the end effector and communicate the monitored function to the printed control board. The wiring circuit comprises a proximal rigid portion fixed to the shaft, a distal rigid portion fixed to the end effector, and an intermediate portion extending from the proximal rigid portion to the distal rigid portion. The intermediate portion comprises a resilient portion and a stretchable portion.
