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.
