Claim 4:
5. A method of deploying or retracting a plurality of lifting tabs of an attachment apparatus to an arthroscopic tool as recited in claim 1, whereby:
the deployment or retracting of said lifting tabs is the result of a linear force provided by a linear force driver, which can be any one or more of the following mechanisms comprising a linear stepper motor, a force transducer, return spring mechanism, or a hand squeeze trigger-style ratchet and release mechanism;
wherein said linear force is transferred from said external element to said pushrod end collar to linearly displace a train of components comprising said pushrod end collar, said pushrods, and said lifting tabs attached to one of the distal ends of the pushrods, wherein said linear force driver is axially constrained by the use of a structural element shaped to fit around a hollow tube that defines much of the axial portion of the arthroscopic tool's structure and be axially in between a tab and tool collar that are both fixed to said tool tube but separated by a finite distance.
