A surgical instrument and a method for using the instrument are provided. The instrument can include a tubular member. A grasper can extend within the tubular member. The grasper can have grasping members each with a distal body. An opening can be formed in an inner surface of each distal body. The grasping members can pivot between an open and a closed configuration to engage a body vessel or tissue. A cutting device can extend within the tubular member. The cutting device can have a cutting member with a cutting edge. The cutting member can be movable between a free and an engaged configuration to sever a body vessel or tissue. When the grasping members are in the closed configuration, the openings of the distal bodies can form a cavity to receive the cutting member to shield the cutting member during navigation within a body of a patient.
