Patent ID: 7883522

Claim:
A minimal incision maximal access working tube assembly comprising: a first hemicylindrical member having at least a first upper pivot axis nearer a proximal end of said first hemicylindrical member and at least a first lower pivot axis nearer a distal end of said first hemicylindrical member; a second hemicylindrical member having at least a first upper pivot axis nearer a proximal end of said second hemicylindrical member and at least a first lower pivot axis nearer a distal end of said second hemicylindrical member, and oriented with respect to said first hemicylindrical member to form a tube shape when brought into close proximity to said first hemicylindrical member; a controllable support having an upper support and a lower support, each of the upper and lower supports allowing independent translation of the respective upper pivot axes and lower pivot axes with respect to the pivot axes of the other support.
