Stainless Steel Biopsy Needles for Diagnostic Accuracy

2025-09-29

Biopsy procedures require needles with exceptional sharpness and durability to extract tissue samples accurately while minimizing patient trauma. A medical device company approached the supplier to develop stainless steel biopsy needles designed for minimally invasive diagnostic applications.

The project required needles with thin walls, strong mechanical resistance, and precise tip geometry. Using centerless grinding, laser cutting, and CNC milling, the supplier produced biopsy needles with enhanced penetration ability and excellent structural stability. Secondary treatments, including polishing and passivation, improved biocompatibility and reduced the risk of tissue damage.

The choice of high-quality stainless steel provided resistance to bending and breakage during procedures, while maintaining compatibility with sterilization methods such as autoclaving and gamma irradiation. Quality inspections under ISO 13485 standards ensured every needle batch met clinical safety requirements.

This case demonstrated how stainless steel biopsy needles play a critical role in cancer diagnosis, pathology testing, and research applications. Reliable customization and stable production enabled the client to expand its product line and strengthen its market position.
