内視鏡用冷却装置

Cooling device for endoscope

Abstract

【課題】高温環境下における観察窓からの視認性を確保して観察をし易くし、検査効率の低下を防ぐことができる内視鏡用冷却装置を提供する。 【解決手段】冷却用流体を流通させて、内視鏡1の挿入部2の観察系が配設された先端部を冷却する内視鏡用冷却装置であって、冷却用流体を供給するコンプレッサ12と、挿入部2の外周側に装着されることで、コンプレッサ12から供給された冷却用流体が流れる冷却用流路を形成する耐熱シース11と、冷却用流体が耐熱シース11の外部に漏れることがないように、かつ、観察系から観察対象が観察可能となるように、耐熱シース11の先端部に設けられた透明な観察窓11aと、観察窓11aの近傍に配設され観察窓11aに対して噴射用流体を噴射するノズル25cと、を備えた内視鏡用冷却装置。 【選択図】図1
PROBLEM TO BE SOLVED: To provide a cooling device for an endoscope that facilitates observation by securing sufficient visibility through an observation window in a high-temperature environment and can thereby prevent the efficiency of examination from deteriorating.SOLUTION: There is provided the cooling device for an endoscope that cools a distal end part of an insertion part 2 of an endoscope 1, where an observation system is disposed, by causing cooling fluid to flow. The cooling device includes: a compressor 12 for supplying the cooling fluid; a heat-resistant sheath 11 that forms a cooling flow passage where the cooling fluid supplied from the compressor 12 flows by being fitted to the outer circumferential side of the insertion part 2; a transparent observation window 11a which is disposed at the distal end part of the heat-resistant sheath 11 so as to prevent the cooling liquid from leaking out of the heat-resistant sheath 11 and to make the object of observation observable from the observation system; and a nozzle 25c which is arranged near the observation window 11a and jets fluid for jetting toward the observation window 11a.
