A retractor for manipulating an object includes a body having proximal and
distal ends, a retraction device, and an actuation device. The retraction
device has a head connected to the distal end of the body, substantially
rigid needles, and an actuator. The head has a pivot. The needles are
pivotally connected to the head about the pivot. The actuator is
operatively connected to the needles and is movably disposed within the
head and/or the body. The actuation device is connected to the proximal
end of the body. The actuation device is operatively connected to the
actuator through the body and, upon actuation thereof, moves the actuator
to selectively rotate the needles between a stowed position where the
needles are stowed within the head and a fully extended position where
the needles are extended out of the head.
