Product Overview

The visualization ring is a miniature metal marker component used with minimally invasive endoscopes and interventional devices, and is a high-precision micro part. Implanted at the distal tip of the device or at a designated marking position, it is clearly visible under X-ray/fluoroscopic imaging, helping physicians locate the device's position, depth, and orientation in real time during procedures. It is an indispensable visualization marker component for luminal endoscopes and interventional consumables. The product is manufactured using micro-precision machining processes, with a tiny size and uniform wall thickness, and can be assembled directly with components such as snake bones, hypotubes, and tip bases, adapting to both single-use and reusable endoscope solutions.

Base Materials and Processes

• Base material: Medical-grade 316L stainless steel

• Processing techniques: Laser micro-cutting, precision stamping, micro-turning; structures such as thin-walled rings, split rings, and C-rings are available

• Surface treatment: Cleaning and deburring, electropolishing, no sharp edges, meeting medical cleanliness requirements; gold plating available on request

• Structural forms: Full rings, C-shaped split rings, segmented visualization rings, adapting to different assembly and fixation methods (press-fitting, spot welding, snap-fit fixation)

Core Product Features

1. Excellent radiopacity: High-atomic-number material, high imaging contrast under X-ray, clear image boundaries, precise positioning, facilitating real-time intraoperative tracking of the device tip position.

2. Miniature precision dimensions: Supports machining of extremely small outer diameters and ultra-thin wall thicknesses; ring dimensions can match various small-diameter snake bones and bending section components without occupying the device's internal channel space.

3. Reliable biocompatibility: Medical-grade raw materials, corrosion-resistant, stable performance in body fluid environments, no leaching, meeting relevant medical device biocompatibility requirements.

4. Strong assembly adaptability: Customizable ring height, wall thickness, inner and outer diameters; split design available for crimp fixation; suitable for endoscope snake bone bases, sheath tips, catheters, biopsy components, and other positions.

5. Clean surface without burrs: Micro-machining + electropolishing processes, smooth edges that will not scratch sheaths, cables, or human luminal tissue.

6. Integrated processing available: Marking, hole drilling, and special-shaped contours can be completed simultaneously; can be produced in the same batch as electrode rings, positioning gaskets, and other parts.

Typical Application Scenarios

Tip markers for flexible endoscopes, single-use endoscopes, interventional catheters, biopsy instruments, and minimally invasive surgical instruments; commonly assembled at the distal end of the snake bone bending section for locating the endoscope bending section position under X-ray.
