A surgical instrument locking handle for securing the position of a first member with respect to a second member. The locking handle includes first and second members and has a locking slide attached to the first member. A locking wiper is attached at one end to the second member and has a free end that is in substantially continuous communication with the locking slide. Movement of the second member with respect to the first member is resisted by a frictional force created between the locking wiper and the locking slide. When a trigger is activated, however, that frictional force is reduced or eliminated, thereby allowing the previously locked members to move freely with respect to one another. The locking handle pursuant to the present invention provides a precise instrument that is easy to manufacture and efficient to use, and which eliminates the need for ridges or ribs on arm or handle members, or for latching mechanisms. When used in conjunction with a remotely manipulated surgical instrument, the locking handle of the present invention allows the surgeon to operate, lock, and unlock the instrument easily with one hand.
