本發明係揭露一種血液流量控制系統及其可調整夾力之夾鑷裝置。此血液流量控制系統包含一偵測單元,一計算單元以及一可調整夾力之夾鑷裝置。偵測單元即時監控生物活體器官之生物分子反應狀態,且藉由偵測結果該計算單元動態地控制夾鑷裝置以調整施於血管之夾力。藉此,血流量控制系統可維持生物分子反應狀態處於一預設範圍,以降低活體器官受傷的風險及提高治癒率。 A blood flow control system and a tension adjustable instrument are disclosed. The blood flow control system comprises a detecting unit, a computing and a tension adjustable instrument. The detecting unit real-time monitors the biomolecular response condition of a living organ, and the computing unit dynamically controls the tension adjustable instrument to adjust the tension of the blood vessel based on the detecting result. Therefore the blood flow control system can maintain the biomolecular response condition on a predetermined range to reduce the risk of the liver organ being damaged and augment the curability.
