Abstract:
An endoscope (1) having a distal end being arranged to be inserted into a body cavity of a patient to be examined and a proximal end which is arranged to be held by a user of the endoscope. The endoscope further comprises a handle (2) arranged at the proximal end of the endoscope, an insertion portion (3) arranged at the distal end of the handle, a bending portion (4) arranged at the distal end of the insertion portion, and two control wires (40, 41) arranged between the handle and the bending portion, said control wires being used to control the bending of the bending portion via control inputs made at the handle. The handle also comprises at least one lever member (21) being arranged to be pivotable about a pivot axis (22), a pulley element (42) located between the proximal end of the handle and the pivot axis of the lever member, and wherein said two control wires are attached to said at least one lever member, a first of said control wires (40) being arranged such that it travels from the at least one lever member (21) in the direction towards the bending portion (4) and the second of said two control wires (41) being arranged such that it travels from the at least one lever member (21) in the direction towards the pulley element (42), it then travels around the pulley element and it then travels towards the bending portion (4). In this way, a simple and effective control mechanism is provided.
