Abstract

The present invention relates to the field of medical technology, and provides a saddle-type microwave irradiator, which includes a casing, and a microwave generator is arranged inside the casing, and the microwave generator includes a solid-state source, a feeding waveguide and a horn antenna, and the solid-state The source is connected to the feeder waveguide, the feeder waveguide is arranged in the inner cavity of the horn antenna, and several layers of barrier plates that fit the inner wall of the horn antenna are arranged along the extension direction of the inner cavity of the horn antenna, and each layer of barrier plates is provided with Diffraction holes, and the number of diffraction holes on the barrier plate away from the end of the feed waveguide increases sequentially; the number of diffraction holes on the barrier plate increases exponentially, and the diffraction holes on adjacent barrier plates are staggered from each other . In the present invention, through the diffraction holes on the barrier plate, the microwaves emitted by the feeding waveguide pass through the barrier plate layer by layer to form superimposition and diffraction, redistribute the electromagnetic waves, make the electromagnetic wave distribution more uniform, and realize uniform energy irradiation on the lesion.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a saddle-type microwave irradiator. Background technique

[0002] Microwaves have been used in clinical medical treatment for nearly 50 years. The principle of traditional microwave treatment is to emit microwaves to human body parts to make water molecules in human tissues rub against each other to generate heat, and use this heat to promote blood circulation. In order to achieve the purpose of treating chronic diseases, generally speaking, patients can feel the warmth of microwave irradiation.

[0003] The existing patent CN206138589U, the patent name "saddle-shaped physiotherapy radiator", includes a shell, a cover, a connector, a feed waveguide, a fluorescent tube and a coaxial cable. The shell is in the shape of a semicircle saddle, and the upper opening of the shell is detachable The ground is equipped with an arc-shaped cover, and the feeding waveguide is arranged...

Examples

Embodiment 1

[0031] see Figure 1 to Figure 3 As shown, this embodiment provides a saddle-type microwave irradiator, including a housing 1 and a microwave generator 3. The housing 1 includes a main housing 101 and an auxiliary housing 101 that is rotatably connected to both ends of the main housing 101 through a damping shaft 2. Shell 102. Specifically, the damping shaft 2 includes symmetrically arranged bushings 201 integrally formed at both ends of the main shell 101 and shaft columns 202 integrally formed on both sides of the end of the auxiliary shell 102. The inner wall of the bushing 201 is along the A pair of damping grooves 203 are symmetrically arranged in the direction of the central axis of the shaft sleeve 201, and a number of grooves 204 are evenly arranged on the outer wall of the shaft column 202 along the direction of the central axis of the shaft column 202, and each of the grooves 204 is provided with a There is a spring 205, on which a damping piece 206 is fixed, and the...
