Abstract
A method of assembling the endoscope, the endoscope including a handle including a wire receiving unit rotatably connected to an operating unit; a distal tip unit configured to be inserted into a patient’s body cavity; an endoscope shaft connecting the endoscope handle and the distal tip unit; and at least one steering wire, a proximal end portion of which being held by or fixed to the wire receiving unit, the steering wire being configured to be pulled by rotating the operating unit, thereby tilting the distal tip unit in at least a defined first direction, wherein the proximal end portion of the at least one steering wire is wound around/on the wire receiving unit for at least one full turn.
Claims6
A method of assembling an endoscope having a handle comprising a rotatable operating wheel, and a wire drum comprising grooves including a first groove, a second groove and a third groove, the grooves extending in a circumferential direction of the wire drum, a distal tip, steering wires including a first steering wire and a second steering wire, and a shaft between the handle and the distal tip, the method comprising:
- connecting a distal end portion of the first steering wire to the distal tip;
- connecting a distal end portion of the second steering wire to the distal tip;
- guiding the steering wires along the endoscope shaft to the handle;
- winding the first steering wire for at least one full turn around the wire drum in a clockwise direction;
- winding the second steering wire for at least one full turn around the wire drum in a clockwise direction;
- tensioning the first steering wire by pulling the proximal end portion of the first steering wire;
- affixing the first steering wire to the wire drum,
- tensioning the second steering wire by pulling the proximal end portion of the second steering wire;
- and
- affixing the second steering wire to the wire drum.
