Title:
取り外し可能な偏向デバイスを備える内視鏡画像化システム
Document Type and Number:
Japanese Patent JP4691361
Kind Code:
B2
Abstract:
A steerable endoscopic sheath has a proximal end, a distal end and a working channel lumen disposed therein. A plurality of solid state light emitting devices such as light emitting diodes are positioned near the distal end of the sheath and are selectively energized to illuminate internal body tissues. An imaging device such as a photo diode or CCD array creates an image from light reflected from the tissue. The distal tip of the endoscopic sheath is selectively moveable with a deflection device that is insertable into the sheath. The deflection device includes a tip deflection mechanism that allows a user to move the tip of the deflection device. With the deflection device inserted in the sheath, movement of the distal tip causes a corresponding movement in the distal tip of the sheath. The distal tip of the sheath has a shape retaining mechanism that allows it to retain the shape imparted by the deflection device once the deflection device is removed from the sheath.
