Description
PEEK is a thermoplastic polymer.
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.
Compatibility with conventional instrument sterilization methods
– PEEK offers complete compatibility with standard sterilization approaches, including autoclave (or steam), gamma radiation and EtO sterilization.
