ENDOSCOPE ASSEMBLY

摘要

An endoscope assembly (10) includes a housing (20) having an outwardly extending tube (14) with the free end (16) adapted for insertion into a body cavity. A laser (24) is contained within the housing which emits an output beam through the free end of the tube. A light sensor (26) detects light in a predetermined color range which impinges upon the free end of the tube and generated an output signal (28) representative thereof. A circuit (30) disables the laser in response to the output signal from the light sensor.
