Single-use coaxial needle

SINGLE-USE COAXIAL NEEDLE

Single-use Coaxial Needle

Intended for tissue exploration or for establishing an access tract through tissue.

Product features

More options

Available in 13 G, 14 G and 15 G specifications, with seven inner/outer diameter combinations and four lengths for varied clinical requirements.

More visible

A specially finished needle tip provides accurate, clear imaging.

More convenient

Graduation marks and an adjustable depth-stop ring support intuitive puncture positioning.

More efficient

One puncture supports repeated sampling or ablation, helping reduce patient burden.

More precise

A tri-bevel needle tip supports easier, more precise puncture.

Clinical applications

1. Clinical departments: ultrasound, interventional radiology, oncology, endocrinology, nephrology, pulmonology and thoracic surgery, among others.

2. Compatible devices: ablation needles, biopsy needles, syringes, endoscopes and ultrasound probes, among others.

Performance features

Single-use coaxial needle

Tri-bevel inner-needle tip

The tri-bevel tip is designed for efficient puncture with less tissue trauma, reduced adherence and lower infection risk.

Depth-stop ring

The light-green silicone two-step ring secures the sheath and controls depth; used with the outer-needle markers, it improves depth visibility during puncture.

Textured outer-needle distal section

The textured surface is designed to provide ultrasound echo and wave-superposition performance.

Luer connection

The needle body and cannula connect to the Luer cap and hub respectively; the Luer connection between the inner and outer needles supports stability and reliability.

Device-use illustration

1
Use step 1

Make a small skin incision at the intended insertion site using a scalpel.

2
Use step 2

Position the depth-stop ring according to the graduation marks, then puncture.

3
Use step 3

After reaching the target, remove the inner needle, retain the outer needle and insert a compatible ablation or biopsy needle.

4
Use step 4

Advance the ablation needle, or a cocked biopsy needle, to the intended position through the outer needle.

5
Use step 5

After ablation or biopsy, remove the ablation or biopsy needle.

6
Use step 6

For repeated treatment or sampling through the same site, adjust the angle as needed; after completion, reinsert and rotate the inner needle before withdrawal.
