AI Technical Summary
The existing process for fixing the distal end of the steel wire rope for the endoscope insertion section is cumbersome, difficult to install, and seriously affects production efficiency.
The design employs a rope-threading channel for assembly components, which leads to the traction area. The traction force is transmitted by using a limiting part that cooperates with the traction area, thus avoiding welding operations.
It reduces assembly difficulty, improves production efficiency, ensures smooth bending of the insertion part, and enhances safety and structural stability.

Abstract
Claims
1. A pulling wire assembly device for an endoscope, characterized by, The assembly device has a rope channel for threading a traction rope that applies traction force. The rope channel extends to the traction-receiving part of the assembly device, which is a part on the assembly device that is limited and matched with the limiting part of the traction rope, so as to transmit the traction force and realize the bending action of the insertion part of the endoscope.
2. The assembly device of claim 1, wherein, The rope-threading channel includes a receiving section, which is capable of accommodating the limiting part; Alternatively, the traction-affected part is the distal end face of the assembly device.
3. The assembly device of claim 2, wherein, The rope-threading channel further includes a main body section, and the receiving section is connected to the main body section. In the axial direction of the assembly device, the projected area of the limiting portion is larger than the projected area of the main body section, wherein: The cross-sectional area of the receiving section gradually decreases from the distal end to the proximal end of the assembled device. And / or, a step is provided at the connection between the receiving section and the main body section, and the limiting part abuts against the step for limitation.
4. The assembly device of claim 1, wherein, The assembly device is a snake skeleton, a front end mount, or an adapter mounted between the snake skeleton and the front end mount.
5. The assembly device of claim 1, wherein, The inner wall forming the rope-threading channel is provided with a groove.
6. The assembly device of claim 5, wherein, The assembly device is provided with an installation channel for installing internal components of the insertion part. The installation channel and the rope passage are separated by a wall structure. While forming the groove, the wall structure protrudes into the installation channel to divide the installation channel into a first region and a second region.
7. An insertion part, characterized in that, include: The assembly device and traction rope as described in any one of claims 1-6, wherein the traction rope is threaded through the rope threading channel, and the traction rope has a limiting portion that is in a limiting engagement with the assembly device.
8. The insertion portion according to claim 7, characterized in that, The distal end of the traction rope is bent to form the limiting part; And / or, in the rope-threading channel, the traction rope and the assembly device are bonded together.
9. The insert of claim 8, wherein, The limiting portion includes a first part and a second part, the first part being connected to the distal end of the second part, and the distal end of the first part being bent toward the direction of the second part to form an arc-shaped transition structure at the connection between the first part and the second part.
10. An endoscope characterized by comprising: Includes the insertion portion as described in any one of claims 7-9.
