Claim 9:
10. A disposable, single-use endoscope with a cannula that includes a permanently mounted, integrated surgical tool operated under video control, comprising:
an elongated cannula and a manually operated control movable relative to the cannula, a working channel in the cannula, a surgical tool at a distal portion of the cannula, and an imaging module at the distal end of the cannula, said imaging module having a field of view and a camera axis;
wherein:
said surgical tool is permanently secured to said manually operated control to move distally and proximally relative to the cannula with movement of the control relative to the cannula, between a retracted position at which the tool is within the working channel and an extended position at which the tool protrudes distally from the channel; and
said surgical tool comprises a grasper comprising a pair of resilient jaw portions that include: (i) distal portions biased to move away from each other and toward and into an open position as the grasper moves distally relative to the cannula toward and into its extended position and terminate in claws that are spaced from each other when the grasper is in its extended position and engage each other when the grasper is in its retracted position; and (ii) proximal portions that are at a proximal end of the grasper and are arch-shaped and configured to engage an inside wall of said working channel and move the distal portions toward and into engagement with each other as the grasper moves proximally relative to the cannula;
wherein as the grasper moves distally relative to the cannula toward and to its extended position said grasper bends to move the distal portions of the resilient jaws toward the imaging module and the camera axis such that said claws are in said field of view.
