The operation is difficult, and its main difficulties lie in the control of bleeding during surgery, the treatment of renal cross-section, and the protection of renal function. However, because its concept of preserving renal function has been recognized by the domestic and international urology community, this operation has a good prospect.

[0003] During the operation, the operation needs to be performed in an almost bloodless state to minimize the amount of bleeding. In this case, the low-temperature device hose needs to be wrapped around the periphery of the renal artery to protect it from low temperatures. However, when the patient undergoes surgery on the operating table, the hose is easily attached to the operating table when extended to the operating table, and is prone to bending, which results in the inability of the zero-degree saline to circulate at a low rate, reducing the effect of the device's low-temperature protection.

[0004] Therefore, we proposed a renal artery intraoperative hypothermia device to solve the above problems. Utility Model Content
