Purpose

1. Traction wire anchoring connector: after singulation, each individual part is a traction wire fixing head, used to clamp and rivet the traction steel wire, transmit the pulling force to the first segment of the snake bone, and enable the bending action of the snake bone.

2. Connected-strip batch processing: multiple groups of traction ends are arranged in an array on a single substrate; processing, cleaning, and passivation processes remain in connected strips, preventing loss of tiny parts, ensuring dimensional consistency of each piece, and making it suitable for mass production.

3. Material advantages: high-elasticity copper alloy (beryllium copper / red copper) is selected, with good toughness; riveted clamping of the steel wire is not prone to cracking, and it is resistant to fatigue under repeated stress, making it suitable for the bending tension conditions of single-use endoscopes.

Process characteristics

Substrate: beryllium copper / red copper sheet, integrally formed by precision laser / chemical etching

Connected-strip array structure with narrow connecting bridges; individual traction ends can be snapped off during use

High-precision contour and rivet hole dimensions, burr-free edges, and medical-grade clean treatment

Customizable shape, hole diameter, and array quantity to match laser snake bones of different specifications
