It is a biocompatible material with high tensile strength, heat resistance, and hardness, while also the anti-fatigue performance of PEEK material is the best among all current materials.
These excellent properties make it an ideal choice for laparoscopic instruments.
Bioinert
- PEEK is a true biomaterial, and multiple studies have shown that the polymer is not cytotoxic, genotoxic, or immunogenic.
