Abstract
A surgical instrument is disclosed comprising a base having a tray, a first member and a second member. A first and second top arm are coupled near the proximal end of the base. At least one bottom finger is coupled to the distal end of the first member and at least one top finger is coupled to the distal end of the first top arm. At least a first lifting arm is located between the first member and the first top arm, said lifting arm comprising a cam for engaging the first top arm. Rotation of an adjustment member positioned near the proximal end of the first member engages at least one lifting arm. As the lifting arm moves towards the distal end of the first member, the cam engages and lifts the first top arm, displacing the first top finger to a separation distance from the bottom finger.
