1. An apparatus comprising:
a pair of jaw members rotatably coupled adjacent to a proximal end of each jaw member of the pair of jaw members, wherein the pair of jaw members define opposing outwardly-facing curved channels disposed between the proximal end and a distal end of each jaw member of the pair of jaw members and the opposing outwardly-facing curved channels are configured to slidably engage a distal pin, and wherein each jaw member of the pair of jaw members includes an outwardly-facing concave end surface adjacent the distal end; and
a bracket that defines a distal socket that receives the distal pin,
wherein as the pair of jaw members are motivated in a distal direction relative to the bracket toward the distal pin, engagement of the distal pin with the outwardly-facing curved channels imparts outward rotation to the pair of jaw members to cause the distal ends of the pair of jaw members move outwardly transversely to the distal direction while the distal ends translate in the distal direction.
