Abstract
An endoscope system, comprises an endoscope device that includes a handle, a shaft projecting from the handle, a flexible tip coupled to a distal portion of the shaft, and a pair of pull wires extending from the handle portion through the shaft portion and coupled to the flexible tip. The handle portion includes a control wheel assembly coupled to the pair of pull wires. The handle includes a control lever coupled to the control wheel assembly. Manipulation of the control lever causes rotation of the control wheel assembly, which then causes deflection of the flexible tip via the pull wires. The control wheel assembly comprises at least two control wheels. 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 system.
