An endoscopic apparatus for dissecting a blood vessel includes a endoscopic barrel having a plurality of lumens, one of the lumens being dimensioned for receiving an endoscope, a handle disposed at a proximal end of the endoscopic barrel, at least two fingers having distally curved ends for dissecting and cauterizing the desired blood vessel, and a displaceable cone portion disposed over a distal end of the endoscopic barrel. The cone portion has a first position concealing the at least two fingers and a second, extended position exposing the at least two fingers. A control rod extends between the handle and each of the fingers such that movement of the control mechanism between a first position and a second position produces a predetermined movement of the respective finger.
