Abstract
Sterilizable electronic video cameras for an endoscope are provided. The electronic video camera comprises an enclosure, a lens cell, a lens cell holder, an image sensor, a motorized focusing system, and switch control. The enclosure comprises a housing and a cover, the housing defining a cavity therein. The cover has a window disposed therein, the housing and cover adapted for hermetic coupling. The lens cell is slidably disposed in the lens cell holder. The image sensor is in optical communication with the lens cell and window. The motorized focusing system is adapted to axially reciprocally move the lens cell relative to the lens cell holder controlled by the switch. The switch control is activated external to the enclosure and is hermetically sealed therewith. The lens cell, lens cell holder, image sensor, and the motorized focusing system, as an assembly, are coupled to the cover and disposed within the cavity.
