Description

Technical Field

[0001] The invention relates to the field of neutron capture therapy devices, and in particular to a micro-reactor neutron capture therapy device. Background Art

[0002] Boron neutron capture therapy (BNCT) destroys cancer cells through nuclear reactions in tumor cells. Its principle is as follows: First, a special boron-containing compound is injected into the patient. This compound has a strong affinity with cancer cells. After entering the human body, it quickly accumulates in cancer cells, while it is rarely distributed in other tissues. This boron-containing compound is non-toxic and harmless to the human body, and has no therapeutic effect on cancer. At this time, an epithermal neutron ray is used for irradiation. This ray does not cause much damage to the human body, but the neutrons can produce a strong nuclear reaction with the boron that enters the cancer cells, releasing a very lethal ray. The range of this ray is very short, only the length of a cancer cell. Therefore, only cancer cells are killed without damaging surrounding tissues. This technology that selectively kills only cancer cells with complex shapes without damaging normal tissues is called boron neutron capture therapy.

[0003] However, the existing neutron capture therapy device is not convenient to effectively cover the irradiation port, which easily causes neutron leakage during use, and the treatment table of the existing neutron capture therapy device is not convenient to adjust and store, so that after use, the operating table is still at the front of the irradiation port, causing certain obstructions, making the device not simple enough and inconvenient to use and maintain. Therefore, a micro reactor neutron capture therapy device is proposed. Summary of the invention

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] Preferably, the rotation adjustment mechanism includes a first oblique block, a vertical rod, and a second oblique block. The first oblique block is fixedly connected to the front side of the threaded cylinder, the upper inner wall of the operating frame is fixedly connected to the vertical rod, and the second oblique block is fixedly connected to the vertical rod. The side surfaces of the first oblique block and the second oblique block that are close to each other are slidably connected to each other.

[0008] Preferably, the telescopic support platform mechanism includes a supporting inclined platform, a slide rail, a first hydraulic rod, a support plate, a slide groove, a slide plate, and a slide rod. The first hydraulic rod is fixedly installed on the lower inner wall array of the operating frame, and the upper end of the first hydraulic rod is fixedly connected to the support plate. Slide grooves are provided on the left and right sides of the support plate, and a slide plate is slidably arranged in each of the slide grooves. The ends of the slides on both sides that are away from each other are fixedly connected to the slide rod, and the slide rods on both sides are respectively slidably arranged in the slide rails on both sides.

[0009] Preferably, the shielding plate is arranged at the front end of the irradiation port in the operation frame, the vertical rod is arranged at the front side of the fixing plate, and the rear side of the lower end of the vertical rod is fixedly connected with a second inclined block.

[0010] Preferably, the left and right sides of the upper end surface of the fixing plate are rotatably connected to the upper inner wall of the operating frame through spring hinges, and the left and right sides of the threaded cylinder are rotatably connected to the lower ends of the telescopic rods on both sides respectively.

[0011] Preferably, the side surfaces of the support ramps on both sides that are close to each other are arranged symmetrically and inclined to each other, and the support plate is arranged between the support ramps on both sides.

[0012] Preferably, the sides of the slides on both sides that are close to each other are slidably disposed in the slide grooves on both sides, and the sides of the slides on both sides that are away from each other extend to the two outer sides of the support plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1.

At the same time, when moving down, the shielding plate can be moved to the front side of the irradiation port to shield it. When moving up, the threaded barrel moves up first. At the same time, because the first inclined block fixedly connected to the front side of the threaded barrel and the second inclined block fixedly connected to the rear side of the lower end of the vertical rod are slidably fitted with each other, when the threaded barrel moves up, the first inclined block and the second inclined block will cooperate with each other to overcome the force of the spring hinge and rotate backward, thereby enabling the shielding plate to rotate backward while moving up, thereby avoiding obstruction to the irradiation port due to itself during use.

[0016] 2. At the same time, the support plate can be driven to move up and down by the extension and retraction of the first hydraulic rod. Since slide plates are slidably arranged in the slide grooves provided on both sides of the support plate, and the slide rods fixedly connected to the slide plates are slidably arranged in the slide rails, when the support plate moves up and down, the slide rods can be driven to slide in the slide rails, and the slide plates can be driven to slide in the slide grooves, so that the slide plates on both sides can be stretched and opened away from each other when the support plate moves up, and can be stored when it moves down.

[0017] The device can flexibly cover the irradiation port and conveniently store and unfold the treatment operation table, thereby improving the convenience of use. BRIEF DESCRIPTION OF THE DRAWINGS
