A forceps includes first and second shaft members, each having a jaw member disposed at a distal end thereof. The first and second shaft members are pivotably coupled to one another toward the distal ends thereof and are moveable relative to one another between an open position and a closed position for moving the jaw members between a spaced-apart position and an approximated position. A knife assembly including a handle and a knife extending from the handle is also provided. The knife assembly is selectively translatable between a retracted position and an extended position, wherein the knife extends between the jaw members. The handle is disposed between the first and second shaft members and is configured to block further closure of the first and second shaft members beyond the closed position, thereby defining a minimum gap distance between the jaw members.
