<原著>前方斜視型panendoscopeとしてのGIFtypeKの検討

概要

論文の詳細を見る
The Olympus, GIFtypeK is the only oblique-forward viewing upper gastrointestinal panendoscope in the world. Compared with the forward-viewing GIFtypeD2,the objective lens of the GIFtypeK is placed 30 degrees oblique angle to the longitudinal direction of its distal end. The GIFtypeK's distal end is metaltipped to make easier passage into the esophagus. But it is 160 degrees of up angle that is only 10 degrees greater than the GIFtypeD2. Then, the GIFtypeK has still some blind areas at the angles, which might exist in many gastric lesions. If the GIFtypeK's shaft is made flexible the same as the GIFtypeD3 and its diameter is made slender the same as the GIFtypeP2,the GIFtypeK may be used continuously as the only oblique type panendoscope that enters into the esophagus and examines precisely the entire upper gastrointestinal tract.
