Claim 2:
3. A system including the apparatus to an arthroscopic tool recited in claim 1:
wherein said attachment is attached to an arthroscopic tool;
said arthroscopic tool having a long slender hollow tube;
said tool tube disposed through a tab near the opposite end of the tool tube opening where a camera or scope lens is situated;
said tool tube disposed through a tool collar that is offset from the center but with a finite distance from said tab;
said attachment coupled to said arthroscopic tool after sliding said tool tube through the bore of the pushrod end collar, in between the pushrods and through the bore of the pushrod guide sleeve;
wherein the combined axial dimension of the pushrod end collar, axial distance of said external element, axial distance between the pushrod end collar and pushrod guide sleeve, and axial dimension of the pushrod guide sleeve is such that the pushrod guide sleeve does not extend over or past the lens opening;
and the axial distance between the pushrod end collar and pushrod guide sleeve is larger than the axial displacement of the pushrod end collar needed to fully deploy the lifting tabs;
and a linear force driver, which can be any one or more of the following mechanisms comprising a linear stepper motor, a force transducer, a return spring mechanism, or a hand squeeze trigger-style ratchet and release mechanism.
