A blunt laparoscopic dissector device is provided which includes an elongate dissector element including a "finger-like" flexible distal end portion. A cylinder or barrel member disposed at one end of a pair of pivotable control arms provides rotatable mounting of the dissector element. A control assembly, including a control rod connected to the other control arm and extending along the length of dissector element, exerts a force on the dissector element so as to produce the desired curvature of the flexible distal end portion. A locking mechanism maintains the force on the dissector element so as to maintain the desired curvature. Rotation of the dissector element within the cylinder enables a surgeon to effect control of the movement of the tip thereof while holding the device in a comfortable stationary position.
