Abstract:
An electromechanical driver assembly for remotely driving surgical attachments having turning members therein, comprising:a flexible shaft including at least two flexible and axially rotating members disposed within the shaft, said rotating members having distal and proximal ends, each rotating member being capable of transmitting a torque applied to the proximal end thereof, therealong to said distal end thereof, said distal ends including means for coupling to said corresponding turning members of said surgical attachments; at least one steering wire disposed along the shaft and configured to steer the flexible shaft; and a handle portion including at least two selectively engageable motors disposed therein and coupled with corresponding ones of said rotating members whereby selective engagement of either of the at least two motors causes the corresponding rotating shaft to rotate, thus transmitting a torque to a corresponding turning member of a surgical attachment.
