In the fields of interventional radiology, oncology, pain management, dermatology and medical aesthetics, puncture and biopsy needles have evolved far beyond a simple tool. They serve as the core functional components of minimally invasive, image-guided and repeatable precision interventional systems. Their core clinical value lies in acquiring the most representative pathological samples or delivering targeted local therapy with minimal tissue trauma.

Dual Roles of Puncture Needles: From Diagnosis to Treatment

1. Diagnostic Puncture

This is the most traditional application of puncture needles. Whether for CT, ultrasound or MRI-guided percutaneous biopsy of pulmonary nodules, liver space-occupying lesions and breast masses, or endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA), the needle is designed to safely and accurately retrieve sufficient, high-quality cells or tissue strips. Its performance directly affects the accuracy of pathological diagnosis and subsequent treatment planning. For instance, genetic testing for lung cancer requires tissue samples of adequate volume and viable cells to meet the requirements of next-generation sequencing (NGS) and other molecular assays.

2. Therapeutic Puncture

Puncture needles act as access channels to facilitate localized treatment, covering the following applications:

• Ablation therapy: The needle is placed first to locate lesions and establish access prior to radiofrequency ablation, microwave ablation and cryoablation.
• Drainage and drug injection: Used for aspiration and drainage of cysts and abscesses, as well as precise administration of medications such as corticosteroids, ozone and platelet-rich plasma (PRP) into joint cavities and around nerve roots.
• Pain management: Applied in interventional pain procedures including nerve block and pulsed radiofrequency therapy.
• Medical aesthetics and regenerative medicine: Microneedles are used for mesotherapy, collagen induction and transdermal delivery of drugs and nutrients.

Core Performance: The Trinity of Geometry, Material and Surface Treatment

A high-performance puncture needle is the integrated achievement of geometric design, material science and surface engineering.

• Geometric design: The bevel angle of the needle tip, sharpness of cutting edges, and the balance between rigidity and flexibility of the needle lumen jointly determine puncture feel and efficiency. For example, coaxial needles for deep tissue biopsy demand extremely high fitting precision between inner and outer cannulas, so as to maintain a stable access tract during repeated sampling.
• Material selection: Manners Technology offers puncture needles made from medical-grade 304/316L stainless steel and nickel-titanium (NiTi) alloy. Stainless steel features outstanding rigidity and strength, suitable for most biopsy procedures. Nickel-titanium alloy possesses superelasticity and shape memory effect, delivering excellent trackability and fracture resistance when navigating curved anatomical pathways. It is particularly ideal for vascular intervention and procedures at complex anatomical sites.
• Surface treatment: Electropolishing creates an ultra-smooth needle surface, which remarkably reduces tissue friction and puncture resistance, improves patient comfort and minimizes tissue damage. Special coatings such as hydrophilic coatings further lower friction and facilitate smooth advancement through catheters or sheaths.
