technical field

The invention relates to the technical field of medical devices, in particular to a tumor microwave ablation needle with temperature control function.

Background technique

With the development of tumor minimally invasive technology, microwave thermal ablation technology has gradually been recognized and widely used in the field of clinical medicine. Microwave ablation uses the thermal effect of microwaves to heat tumor tissue to denature and coagulate proteins to achieve the therapeutic purpose of eliminating tumors in situ. Under the guidance of B-ultrasound and CT images, direct percutaneous puncture to the tumor site realizes minimally invasive surgery in the true sense. At present, the microwave ablation products used clinically can basically achieve a spherical shape in terms of ablation morphology, but whether it can ensure the complete destruction of the tumor is undoubtedly a crucial parameter in the process of tumor ablation. At present, it is clinically judged whether the tumor has reached the expectation The methods for ablation range include: (1) inserting another bypass thermometry needle at the edge of the tumor to monitor the tumor ablation temperature; (2) suspending the microwave output after a certain period of ablation, and observing the changes of the tumor tissue with B-ultrasound or CT images. There are certain deficiencies in the above two judgment methods. The bypass temperature measurement increases the difficulty of the doctor's secondary positioning. B-ultrasound or CT is sometimes judged by the vaporization image in the process of tumor ablation, and the operating doctor needs to have superb medical skills and certain experience. .
