Dynamic monitoring method and system for kidney tissue oxygen saturation in kidney unit retaining operation

According to the method and the system for dynamically monitoring the oxygen saturation of the kidney tissue in the kidney preserving unit operation, the current research situation of a near infrared spectrum technology in the kidney is combined, and different types of kidney blood vessel blocking states are designed; the near infrared spectrum technology is used for detecting the difference of the values of the blood oxygen saturation of the renal parenchyma under different blocking modes of the renal blood vessels in the reserved renal unit operation, the threshold range of the blood oxygen saturation of the renal parenchyma after the good blocking of the renal blood vessels is found out, and the serious bleeding probability caused by the inexact blocking of the blood vessels in the reserved renal unit operation is reduced. Meanwhile, a clear operation view field can be kept, the positive rate of the incision edge is reduced, and therefore the operation effect is improved. According to the system, a robot o
