FLUID DELIVERY NOZZLE OF ENDOSCOPE AND ANGLE ADJUSTING INSTRUMENT OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a fluid delivery nozzle of an endoscope facilitating the discrimination of an angular position relative to the distal end of an insertion section of the endoscope, easily applying rotating operation force for the angular adjustment, and having superior adjusting work efficiency.;SOLUTION: This fluid delivery nozzle of the endoscope includes: a tubular insertion support section insertedly supported in a nozzle support hole formed at the distal end of the insertion section of the endoscope, so that an angle can be adjusted around the axis with respect to the nozzle support hole; a nozzle head projecting from the nozzle support hole, with the insertion support section insertedly supported in the nozzle support hole; a fluid delivery outlet opened at the peripheral section of the nozzle head and communicated with the fluid flow passage in the interior of the endoscope insertion section, with the insertion support section supported in the nozzle support hole; a noncircular force-application/indicator section formed at the peripheral section of the nozzle head with its location changed from the fluid delivery outlet and serving both as a force application section for the angular adjustment around the axis with respect to the nozzle and as an indicator section indicating the angular position.;COPYRIGHT: (C)2010,JPO&INPIT
