Various surgical devices are provided for shielding tissue from potentially harmful byproducts generated by surgical devices that use energy to treat tissue. In general, a shield member is provided that includes a connector element for removably connecting the shield member to a surgical device and a shield body configured to extend adjacent to an energy-emitting end effector of the device. When energy is delivered to treated tissue captured by the end effector, the shield body can be configured to serve as a physical barrier between the end effector and tissue adjacent to the treated tissue. In this way, the shield member can protect the adjacent tissue from potentially harmful byproducts of the end effector, e.g., heat and steam, and/or can deflect the byproducts back toward the treated tissue.
