Abstract

The invention discloses a microwave ablation device. The microwave ablation device comprises a microwave generator, a controller, a microwave waveguide and a microwave antenna, the controller is electrically connected with the microwave generator, and the microwave waveguide is connected with the microwave generator and the microwave antenna respectively; wherein the microwave generator is used for generating microwaves; the microwave waveguide is used for transmitting microwaves to the microwave antenna; the microwave antenna is used for receiving microwaves and transmitting a first microwave beam and a second microwave beam which are the same in frequency and opposite in direction, so that the first microwave beam and the second microwave beam form a standing microwave at a target object; and the controller is used for focusing the standing microwave antinode of the standing microwave on a target part and forming 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. Background technique [0002] Microwave ablation technology is a new technology developed in the past ten years, which is a combination of modern medical imaging and microwave technology. [0003] 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. [0004] 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 [0005] T...
