Orthopedic Implants
PEEK medical material is widely used in the orthopedic field, especially for spinal implants, such as intervertebral fusion cages, screws, and plates. The stiffness of PEEK is similar to that of human bone, which helps better distribute and transmit loads, reducing stress shielding, and promoting natural bone healing.
Dental Applications
PEEK applications in the dental field are also increasing. It is used to make dental restorations such as crowns, bridges, and abutments. Compared to metals, PEEK medical material offers better aesthetics and does not cause allergic reactions in patients.
Surgical Instruments
PEEK medical material, due to its high strength and heat resistance, is suitable for manufacturing surgical instruments such as forceps, scissors, and drills. These tools can withstand high-temperature and high-pressure sterilization processes without losing their mechanical properties.
Neurosurgical Applications
In neurosurgery, PEEK is used to manufacture cranial repair plates and cranial reconstruction devices. PEEK medical material's low density and excellent mechanical properties make it an ideal material for repairing bone defects. Additionally, PEEK medical material can be customized through 3D printing technology to better fit the patient's anatomy.
Joint Replacement
PEEK is also used in joint replacement surgeries to manufacture certain components of artificial joints, such as the liners for knees and hips. Compared to metals, PEEK medical material offers better tribological properties, reducing wear between joint components and thus extending the lifespan of artificial joints.
Cardiovascular Devices
PEEK medical material is also used in some cardiovascular devices, such as catheters, heart valves, and vascular stents. Due to its excellent biocompatibility and blood compatibility, PEEK medical material can remain stable during long-term use and reduces the risk of rejection reactions in patients.
