The biocompatibility of minimally invasive surgical tungsten needles is evaluated through a series of experiments and clinical studies.
First, tungsten needles need to undergo strict quality control during the manufacturing process to ensure that they do not contain harmful substances or impurities. Secondly, tungsten needles need to undergo biological tests to evaluate their biocompatibility and safety in the human body. These tests include acute toxicity tests, subacute toxicity tests, sensitization tests, genotoxicity tests, chronic toxicity tests, etc.
In addition to biological tests, tungsten needles also need to undergo clinical evaluation. In clinical studies, doctors will conduct long-term observation and evaluation of patients treated with tungsten needles to confirm the performance and effect of tungsten needles in the human body.
Combining the results of these experiments and clinical studies, the biocompatibility of minimally invasive surgical tungsten needles can be comprehensively evaluated. If the tungsten needle shows good biocompatibility and safety in the human body, it can be considered a reliable surgical instrument.
