Description

Direct-insertion type therapeutic bed for neutron therapy Technical Field The utility model relates to the technical field of medical instruments, in particular to an in-line therapeutic bed for neutron therapy. Background Neutron therapy, as a high-energy particle radiation therapy approach, has shown significant advantages in refractory tumor treatment due to its unique biological effectiveness. The neutron beam has high linear energy transfer characteristic, can effectively kill hypoxic tumor cells insensitive to traditional photon radiotherapy, but the treatment effect is highly dependent on the spatial coupling relation between the body position of a patient and the neutron beam flow path. The smaller the gap between the tumor position and the neutron source, the better the effect of neutron treatment, and when the distance between the tumor position and the neutron source is increased, the poor treatment effect can be caused because neutron beam current can be scattered or absorbed in the air. In the prior art, as disclosed in patent application CN117064683a, an MRI examination head support includes a fixed base, the top of the fixed base is provided with a slidable adjusting component and a hinged protection component, the adjusting component includes a first fixed bottom plate fixedly mounted on the top of the fixed base, the inside of the first fixed bottom plate is provided with a meshing structure, the protection component includes a support plate fixedly mounted on the outer wall of one side of the fixed base, the top of the support plate is provided with a hinged structure, the adjusting component further includes a movable plate disposed on the top of the fixed base, the top of the movable plate is provided with a rotatable adjusting structure, the adjusting component further includes a second fixed bottom plate fixedly mounted on the top of the fixed base, but the scheme can only adapt to the head and neck spacing of different patients through the depth of the adjusting device, and the distance between the head of the patient and a neutron source cannot be adjusted when the neutron treatment is used. Disclosure of utility model The utility model aims to overcome the defect that the distance between the head of a patient and a neutron source cannot be adjusted in the prior art, and provides a direct-insertion type therapeutic bed for neutron therapy.
