Product Description

Surgical Electrode Knife: High-Quality 304 Stainless Steel Design

Product Description
The 304 Stainless Steel Medical Electrode Knife and Ablation Electrode Needle are electrosurgical instruments designed for precise cutting, coagulation, and tissue ablation in minimally invasive and open surgical procedures. Manufactured from durable 304 stainless steel, these devices conduct high-frequency electrical current from an electrosurgical generator to biological tissue, enabling controlled thermal effects for cutting, sealing vessels, or ablating pathological tissue. The electrode knife is optimized for incisions and dissection, while the ablation needle is designed for focused, deep tissue destruction, such as in tumor ablation or arrhythmia treatment.

Product Processing
Material Selection: High-quality 304 stainless steel rods/tubes/wires, chosen for good electrical conductivity, mechanical strength, and corrosion resistance.
Precision Machining: CNC machining to form the electrode body, shaft, and specific tip geometries (knife edge, needle point).
Tip Formation & Sharpening: For knives: precision grinding of cutting edges. For needles: grinding to form sharp, tapered, or specialized (e.g., multi-tine) tips.
Insulation Application (for certain parts): Coating of non-active sections with biocompatible, high-dielectric-strength insulation materials like PTFE (Teflon™) or ceramic.
Surface Finishing: Electropolishing and passivation for a smooth, clean, corrosion-resistant surface.
Assembly: Attachment of an insulated handle and a standardized connector compatible with electrosurgical generators.
Testing & Validation: Electrical safety testing (impedance, leakage current), functional testing with a generator, and thermal profile verification.
Sterilization & Packaging: Validated sterilization (EtO, Gamma) and sterile barrier packaging.
Product Applications
General Surgery: Cutting and coagulation in open and laparoscopic procedures.
Dermatology & Plastic Surgery: Skin lesion removal, cosmetic procedures.
Oncology (Tumor Ablation): Radiofrequency Ablation (RFA) or Microwave Ablation (MWA) of liver, lung, kidney, bone tumors (using ablation needles).
Cardiology (Cardiac Ablation): Treatment of atrial fibrillation and other arrhythmias (using specialized cardiac ablation catheters/needles).
