A surgical instrument having a handle, barrel and working end effector tip is provided. The barrel is generally tubular, with one end being releasably connected to the handle. The end effector is moveably attached to the other end of the barrel, and may be positioned and operated independently through multiple linkage members connected to a motive power source housed in or attached to the handle. The instrument is operated and controlled by a microprocessor and multidimensional controller or electrical contacts included in the handle. In the preferred embodiment, the end effector is scissor-like, but other end effectors such as graspers, clamps, dissectors or needle drivers, with appropriate operating and linkage members, may be attached to the handle. |
