An endoscope device comprising: a handle; a shaft projecting from the handle, wherein the shaft includes a proximal portion and a distal portion relative to the handle; a tube engagement device adjacent a distal end of the handle for retaining a device tube over the shaft prior to use, wherein the tube engagement device comprises: an inner tube portion for receiving the shaft therethrough; and an outer tube portion formed concentrically over the inner tube portion, wherein an inside diameter of the outer tube portion is configured to fictionally engage an outside diameter of the device tube, and wherein the inside diameter of the outer tube portion is spaced from the outside diameter of the inner tube portion, such that an outside diameter of the inner tube portion is configured to not engage an inside diameter of the device tube; a flexible tip coupled to the distal portion of the shaft; and a pair of pull wires (208, 210) extending from the handle portion through the shaft portion and coupled to the flexible tip, wherein the handle portion includes a control wheel assembly coupled to the pair of pull wires, wherein the control wheel assembly comprises at least two control wheels (800, 802), and wherein each of the at least two control wheels are capable of independent rotation to provide accurate tensioning of the pair of pull wires during assembly of the endoscope device. a handle; a shaft projecting from the handle, wherein the shaft includes a proximal portion and a distal portion relative to the handle; a tube engagement device adjacent a distal end of the handle for retaining a device tube over the shaft prior to use, wherein the tube engagement device comprises: an inner tube portion for receiving the shaft therethrough; and an outer tube portion formed concentrically over the inner tube portion, wherein an inside diameter of the outer tube portion is configured to fictionally engage an outside diameter of the device tube, and wherein the inside diameter of the outer tube portion is spaced from the outside diameter of the inner tube portion, such that an outside diameter of the inner tube portion is configured to not engage an inside diameter of the device tube; an inner tube portion for receiving the shaft therethrough; and an outer tube portion formed concentrically over the inner tube portion, wherein an inside diameter of the outer tube portion is configured to fictionally engage an outside diameter of the device tube, and wherein the inside diameter of the outer tube portion is spaced from the outside diameter of the inner tube portion, such that an outside diameter of the inner tube portion is configured to not engage an inside diameter of the device tube; a flexible tip coupled to the distal portion of the shaft; and a pair of pull wires (208, 210) extending from the handle portion through the shaft portion and coupled to the flexible tip, wherein the handle portion includes a control wheel assembly coupled to the pair of pull wires, wherein the control wheel assembly comprises at least two control wheels (800, 802), and wherein each of the at least two control wheels are capable of independent rotation to provide accurate tensioning of the pair of pull wires during assembly of the endoscope device.
