Nitinol Guide Pins Descriptions
Medical titanium-nickel (Nitinol) guide pins are superelastic, biocompatible surgical instruments used in orthopedics and cardiovascular procedures to guide tools for precise drilling and screw placement. They often meet ASTM F2063 standards for shape memory alloys, offering high durability and flexibility during minimally invasive surgeries
The core material is Nitinol memory alloy, which is used as a high-precision guide device for minimally invasive, interventional, and puncture surgeries in orthopedics.
It is mainly used for intraoperative positioning, puncture, channel establishment, and guiding internal implants.
The Integrated Nitinol Guide Pin is a high-performance surgical instrument designed for orthopedic implant procedures. Manufactured with precision and reliability in mind, this guide pin is essential for accurate guidance and positioning during minimally invasive surgeries. With advanced processing, strict standards, and customizable specifications, it provides surgeons with superior control and patients with safer, less painful treatment.

Nitinol Guide Pin Application:
- Orthopedics (accounting for approximately 65% of the total number of ball head guide pins)
Vertebral augmentation / Posterior Vertebral Kyphoplasty (PVP/PKP): The ball head guide pin precisely punctures the pedicle of the vertebra, avoiding puncturing the posterior wall of the vertebra / spinal canal. It is a standard procedure for the surgery. - Spinal pedicle screw placement: Precise open approach under robot / navigation, reducing the risk of nerve injury.
Minimally invasive reduction of limb fractures (MIPO): Kirschner wire guidance, intramedullary nail positioning, reducing soft tissue dissection.
Arthroscopy / Sports medicine: Guidance for cruciate ligament reconstruction, rotator cuff repair. - Interventional (accounting for approximately 25%)
Peripheral vascular / Nerve intervention: Ball head super-smooth guide pin passes through tortuous blood vessels, reducing the risk of dissection / perforation.
Tumor ablation / Particle implantation: Precise positioning, protecting surrounding normal tissues.
- Others (approximately 10%) Dental implant positioning, biopsy puncture, minimally invasive urology, etc.
