Abstract

The invention discloses a microwave ablation device and system. The microwave ablation device comprises a controller, a microwave generator, a microwave waveguide and a microwave antenna, wherein the microwave generator is used for generating microwaves; the microwave waveguide is respectively connected with the microwave generator and the microwave antenna and transmits the microwaves to the microwave antenna; the microwave antenna is used for transmitting the microwaves to form a plurality of microwave beams; and the controller is electrically connected with the microwave generator, and the controller is used for controlling the microwave generator to focus on a target part through a plurality of microwave beams emitted by the microwave antenna and form an ablation area. The problem that in a microwave ablation operation, a microwave needle needs to be inserted into a human tumor, so that a human body is wounded is solved, and the effect of reducing wounds caused to the human body in the ablation process is achieved.

Description

technical field [0001] Embodiments of the present invention relate to microwave ablation technology, and in particular to a microwave ablation device and system. Background technique [0002] The existing microwave ablation method is to percutaneously puncture a special microwave needle into the central area of ​​the tumor, and generate microwaves at a certain point of the microwave needle. The microwave magnetic field released by it can make the surrounding molecules rotate at high speed and heat up by friction. So that the tissue coagulation, dehydration and necrosis, to achieve the purpose of treatment. [0003] Inserting microwave needles into human tumors will cause great trauma to the human body, especially for tumor ablation deep in the body, which will cause greater trauma. Contents of the invention [0004] The present invention provides a microwave ablation device and system to achieve the effect of reducing trauma generated during the ablation process. [0005...
