DISPOSABLE FLEXIBLE ENDOSCOPE

WIPO Patent Application WO/2023/115851

A1

A disposable flexible endoscope, comprising an operation segment (1) at a proximal end, and an insertion segment (2) at a distal end inserted into a human body. A bendable portion is provided at the front end of the insertion segment (2). The operation segment (2) comprises a housing (3), and a control portion (5) for controlling the bending and steering of a head (4) of the insertion portion. The control portion (5) comprises a rotating disc (51) provided and positioned inside the housing (3), and a locking assembly connected to the rotating disc (51) and capable of locking the rotation of the rotating disc (51). The rotating disc (51) is connected to the bendable portion. The locking assembly comprises a locking member (52), and a flexible rubber member (53) positioned inside the rotating disc (51). The locking member (52) drives the flexible rubber member (53) to be in friction fit with the rotating disc (51), so as to restrain the rotation of the rotating disc (51), thereby limiting the bending of the head of the insertion segment (2).
