Description

Technical Field

[0001] This utility model relates to the field of industrial endoscope technology, and in particular to a two-way structure endoscope. Background Technology

[0002] An endoscope is a multidisciplinary tool that can explore deep into curved tubes and narrow cavities, observe parts that cannot be directly observed by the human eye, observe the internal spatial structure and surface condition in sealed cavities, and enable remote observation and operation.

[0003] The steering mechanism of existing industrial endoscopes almost always consists of a steel wire wound around a rotating shaft. Rotating the rotating shaft drives the steel wire to rotate. The steel wire on the rotating shaft is connected to the steel wire on the rotating head. The steel wire on the rotating shaft then drives the steel wire on the rotating head. In this way, rotating the rotating shaft can drive the rotating head to swing.

[0004] Current endoscopes on the market have complex structures, numerous parts, and are inconvenient to assemble. The steel wires on the rotating shaft and the rotating head are not easily connected and are prone to falling off. Rotating the rotating shaft knob can cause a rebound, and the endoscope's steering steel wires are prone to tangling, affecting use and making maintenance difficult. Manufacturing and use costs are high, and the lifespan is short, greatly reducing market competitiveness. The existing patent, titled "Steering Device for a Two-Way Endoscope" (publication number CN203287615U), has solved the problem of head rebound, but the overall structure is still relatively complex and the use cost is high, requiring further improvement.

[0005] Therefore, there is an urgent need for engineers in this field to develop a two-way endoscope that is simple in structure, easy to use, low in cost, long in service life, and easy to maintain. Utility Model Content
