Disposable
Steep Pulse Ablation Needle
The disposable steep pulse ablation needle is a high-performance medical device specially designed for the ablation of malignant solid liver tumors. It must be used in conjunction with a steep pulse therapeutic system (Model: NPA‑LC01).
The product consists of a metal needle, a handle, a protective sheath, and a connecting cable. Made of SUS304 stainless steel, it features excellent puncture performance and corrosion resistance.
The ablation needle is sterilized by ethylene oxide and is for single‑use only to ensure sterility. It complies with strict chemical and electrical performance standards and is suitable for precise image‑guided tumor ablation procedures in medical institutions.
Product Advantages
The metal needle features a refined design (diameter 1.0 mm, hardness 400 HV0.2) with low puncture force (< 3.8 N), making it suitable for minimally invasive surgery.
Passes 30kV withstand voltage test with impedance < 0.5 S, ensuring stable treatment; ethylene oxide residue is 10 μg/g, with excellent biocompatibility.
It is detectable under ultrasound and CT, enabling real‑time imaging monitoring and improving surgical safety.
Clinical Validation
Has completed a major national science and technology project.
It has successfully achieved ablation of liver cancer in high-risk locations that are considered clinical "no‑go zones" for thermal ablation, and has obtained a Class I product registration certificate issued by the National Medical Products Administration (NMPA).
