Claim 3:
4. The system according to claim 3:
wherein said pushrod guide sleeve is fixed to the tool tube by one countersunk setscrew fastened through a corresponding tap placed on at least one of the two axial distal ends of the pushrod guide sleeve and is approximately 90 degrees offset from the space between one of the pairs of pushrods such that when the setscrew is applying preload, the tip of each setscrew is pressing onto the tool tube to generate sufficient friction or restraining force to keep the pushrod guide sleeve fixed to the tool tube during operation;
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.
