Abstract

Provided in the invention is a detection and protection system for a water cooling fault of tumour microwave ablation. A tumour microwave ablation water-cooling system is a circulating system formed by successive series connection of a water containing device, a peristaltic pump, and a microwave ablation antenna needle by a cooling circulating pipeline; and the microwave ablation antenna needle is connected with a microwave host by a microwave output coaxial cable. The detection and protection system comprises a water flow photosensitive receptor for detecting a water flow signal in the cooling circulating pipeline, an alarm device for carrying out sounding alarming when the water flow photosensitive receptor can not feel a water flow signal, and a control unit for cutting off a microwave host circuit when the water flow photosensitive receptor can not feel a water flow signal. According to the invention, the water flow situation in the cooling circulating pipeline is detected to determine whether a fault occurs at the tumour microwave ablation water-cooling system accurately, thereby guaranteeing safety implementation of the microwave thermal ablation operation. The system having advantages of simple structure and low cost is suitable for popularization and application.

Description

technical field [0001] The invention relates to a system for detecting and protecting the failure of a circulating water cooling system for microwave ablation antenna needles of tumors, belonging to the technical field of medical devices. Background technique [0002] Microwave thermal ablation technology has become the main means of precise and minimally invasive treatment of clinical tumors. It is characterized in that the microwave energy generated by the microwave host is introduced into the tumor in the human body through the ablation antenna needle, and a high-temperature heat field is rapidly generated at the tumor to make the tumor Tissue coagulation death. [0003] The endogenous heat generated by the microwave coagulates and inactivates the tumor tissue, and at the same time conducts retrogradely through the microwave antenna needle (metal component), scalding the puncture path passed by the antenna needle, especially the skin at the puncture point on the body surf...
