摘要：
An end effector for use with a surgical instrument includes a lower jaw an anvil and a resilient member. The anvil is pivotable relative to the lower jaw between a fully opened position and a fully closed position. The resilient member is configured to bias the anvil to remain in the fully opened position when the anvil is in the fully opened position. The end effector may include a closure ring coupled with the anvil that is translatable relative to the lower jaw and configured to engage the anvil at an interface as the closure ring translates proximally relative to the lower jaw to thereby pivot the anvil relative to the lower jaw toward the fully opened position. In various embodiments the resilient member may comprise elastomeric material positioned between the closure ring and the anvil or a pair of springs or resilient arms that engage the anvil.
