Abstract
An endoscope for an optical fiber provides for inflow and outflow of irrigant. A telescope is included having a field of view directed into a working region. The endoscope defines a 'hooded region' with an extended, blunt tip. The optical fiber fits within the endoscope has a side or end firing tip with an emission surface. A guide element is adapted to movably support the optical fiber in a position spaced away from the working region, and limit lateral movement of the tip without preventing longitudinal and rotational movement. An irrigant flow arrangement operates to direct inflowing irrigant over the emission surface of the tip. The fiber is assembled with a fiber coupler, a handle, a fiber port cap, and a travel limiter fixed to the fiber at a predetermined distance from the tip. The travel limiter cooperates with the endoscope and the fiber port cap to limit longitudinal and rotational movement of the fiber.
