Technical Field
[0001] This utility model relates to the field of medical equipment technology, specifically to a microwave ablation host device with precise temperature control. Background Technology
[0002] Microwave ablation therapy for cancer is a novel medical instrument that uses microwaves to treat various tumors. Microwave ablation therapy offers advantages such as high efficiency in generating heat to human tissues, strong penetration, rapid heating, uniform high-temperature thermal field, thorough necrosis of the coagulation zone, minimal impact from blood flow, short operation time, few complications, no damage to surrounding tissues, and good therapeutic effects. It also has the advantage of generating heat both internally and externally simultaneously.
[0003] The existing Chinese utility model patent with publication number CN112790860A discloses a microwave ablation device, including a shell structure and a main unit disposed within the shell structure. The shell structure is made of ABS plastic. The front, rear, and top surfaces of the shell structure are respectively provided with an operation control unit, a heat dissipation unit, and a sloping operating table with a shield. The operation control unit and the sloping operating table are electrically connected to the main unit. The heat dissipation unit is used to cool the main unit and its surroundings within the shell structure. The shield is used to limit the radiated electromagnetic energy within the shell structure from escaping to the outside. The beneficial effects of this invention are: the shell structure of the microwave ablation device is made of ABS plastic, which is compatible with the magnetic resonance environment. The microwave ablation device, combined with magnetic resonance positioning, allows for minimally invasive interventional surgery, reducing the difficulty of operation for doctors, saving surgical time, and reducing trauma to patients; the provided operation control unit and sloping operating table facilitate operation, and the heat dissipation unit ensures the stable operation of the microwave ablation device.
[0004] Based on the search of the aforementioned patents and the findings of existing equipment, the ablation host device used in cryoablation surgery has several drawbacks. Firstly, it cannot precisely control the temperature at the top of the ablation host device during use, leading to an inability to guarantee the stability and safety (focused microwave) of the cryoablation procedure. Secondly, it cannot dissipate heat internally, resulting in excessively high internal temperatures that affect subsequent use. All these issues impact the usability of the device.
