Endoscopy

Abstract

The invention relates to an endoscope (100) consisting of a tubular structure (2) and a control device. The tubular structure (2) consists of an elastic support (3), a lens assembly (4), and a sleeve. The elastic support (3) consists of a distal disc (31), a proximal disc (33), an intermediate disc (32), a first spring and a second spring (34, 35) which are connected between these discs (31, 32, 33) respectively. The lens assembly (4) consists of a lens (41) and a lens module (42). The sleeve is fitted into the lens (41) and the elastic support (3). The control device includes a handle (81), and an angle control module connected to the conduit crane (2). The angle control module can operate to move the far disc (31) and to deflect the first spring (34), thereby controlling the angle of the far disc (31).
