Abstract
An arthroscopic cutting device has an external tube, a knife telescopically received within and rotatably mounted with respect to the external tube, a dc motor drivably connected to the knife and means for controlling the motor to periodically reverse the direction of rotation of the knife about every two revolutions, thus providing increased speed and efficiency in bidirectional cutting action during arthroscopic surgery.
