A support apparatus for a medical device includes a first sleeve, a second sleeve, and a flexible contact member. The first sleeve is configured to be coupled to a first tool member of an end effector assembly that includes the first tool member, a second tool member, and a clevis, in which the first and second tool members are each rotatably coupled to the clevis such that second tool member can be moved relative to the first tool member between a first and a second orientation. The second sleeve is configured to be coupled to the second tool member. The flexible contact member is coupled to the first sleeve and the second sleeve, and is configured be moved between a collapsed configuration when the second tool member is in the first orientation and an expanded configuration when the second tool member is in the second orientation.
