Our first 4 FiberTech (0.7-mm external diameter) ductoscopes broke during the sterilization process at the junction of the metal scope and the plastic handle. Hospital engineers designed and built the perforated silicone sleeve (lower left), which fits over the scope when not in use to protect the junction and to allow for instrument sterilization. The metal cannula protects the junction when the surgeon uses the scope.
