Document Type and Number:
WIPO Patent Application WO/2020/179909
Kind Code:
A1
Abstract:
Provided is an endoscope capable of securing a guide wire and stably holding a treatment instrument. The endoscope has a distal end body (36) which comprises: a raising platform housing (62) opened in a first direction; a treatment instrument outlet (80) opened inside the raising platform housing (62); and a raising platform (60) provided in the raising platform housing (62) so as to be pivotable between a raised position and a lowered position and having a treatment instrument guide surface (60a). An opposing wall section (66) facing the opening at the proximal end of the raising platform housing (62) includes a concave surface (96) formed on the inner side of the raising platform housing (62) and a convex surface (94) formed at a position closer to the opening than to the concave surface (96). When the raising platform (60) is closer to the lowered position than to the raised position, the concave surface (96) and the treatment instrument guide surface (60a) form a treatment instrument holder (99) for holding the treatment instrument; when the raising platform (60) is at the raised position, the convex surface (94) and the treatment instrument guide surface (60a) form a guide wire securing section (98) for securing the guide wire.
