Abstract
Surgical instruments are movable in several different dimensions and about several distinct axes. Surgical instruments include a head portion having a desired tool, a body portion freely moveable in several dimensions with respect to the head to which it connects via a connection or joint, which may be maneuverable and lockable in several head-body orientations. The connection may include one or more cooperative shafts, a rotator that angularly moves the head portion, a joint that translates the angular motion from rotator to the head in any relative orientation of the head portion, a crank that couples the shafts with the head portion, and a collar having an end slot to accommodate one or more of the shafts. In this way, as the shaft moves upward and downward, the head portion is transverse angularly displaced.
