Abstract
A cover for an electrosurgical instrument having a wrist structure and an end effector is provided. The cover includes a hollow elongated structure, which includes a tip cover portion and a base cover portion integrally connected to the tip cover portion. The tip cover portion has a distal end with an opening therethrough sized to receive the end effector of the electrosurgical instrument and is composed of a first, electrically insulative material having a flexibility sufficient to allow the end effector to be manipulated while the end effector is received in the opening. The base cover portion is composed of a second material having a higher tear strength than the first material. The tip cover portion and the base cover portion overlap at an overlap region configured to receive the wrist structure of the electrosurgical instrument when the end effector is received in the opening.
