Nickel-Titanium Guide Pins Description:
Nickel-titanium guidepins are high-performance medical devices made from nickel-titanium alloy, renowned for their exceptional elasticity and shape memory properties. Their outstanding flexibility and recovery ability allow them to navigate complex medical pathways without damaging surrounding tissues.
Our Nickel-Titanium (NiTi) Guide Wires are engineered for superior flexibility, high strength, and excellent biocompatibility, making them ideal for medical applications such as minimally invasive procedures and orthopedic surgeries.

Nickel-Titanium Guide Pins Production Process:
Raw material → Mixed ingredients → Vacuum melting → Sampling analysis after furnace → Hot forging → Hot rolling to 8MM → Pickling → Wellbore annealing (heat treatment) → Wire drawing → Wellbore annealing (heat treatment) → Sampling and testing → Water tank drawing → Continuous annealing → Finished product inspection and testing → Packing → Final shipment
Applications of Nickel-Titanium Guide Pins
1. Cardiovascular Interventions: Nickel-titanium guide pins are commonly used in cardiovascular interventions, such as coronary artery stent implantation and cardiac catheterization. Their high elasticity and flexibility allow them to easily navigate narrow and curved vascular paths, reducing surgical risks.
2. Neurointerventions: In neurosurgery, nickel-titanium guide pins are used for minimally invasive procedures, such as embolization of cerebral aneurysms. Their precise guiding ability and controllability make surgeries safer and more efficient.
3. Urology: These guide pins are widely used in urological procedures, including catheter placement and lithotripsy. Their anti-kink properties and shape memory effect help them smoothly pass through narrow parts of the urinary system.
4. Gastrointestinal Treatment: Nickel-titanium guide pins are used in endoscopic operations of the digestive system, such as polyp removal and intestinal obstruction treatment. Their flexibility and biocompatibility minimize irritation and damage to the gastrointestinal mucosa.
5. Orthopedic Surgery: In orthopedic surgery, nickel-titanium guide pins are extensively applied in spinal correction and fracture fixation. Their high strength and fatigue resistance ensure long-term stability and reliability.
