Description

Movable therapeutic bed for neutron therapy Technical Field The utility model relates to the technical field of medical instruments, in particular to a movable therapeutic bed for neutron therapy. Background Neutron therapy is a new technology in radiotherapy, and compared with traditional X-rays, fast neutrons have the characteristic of high LET (Linear energy transfer), have fast energy loss in biological tissues, can transfer a large amount of energy in a short distance, and have stronger killing effect on tumor cells. During neutron therapy, a patient first injects or orally administers a boron-10 isotope-containing compound, such as Boron Phenylalanine (BPA) and sodium borohydride (NaBH 4), etc. These boron-containing compounds can selectively accumulate in tumor cells and subsequently irradiate the tumor site with a neutron beam. Boron-10 reacts with neutrons to produce high LET alpha particles and lithium-7 particles, which release a large amount of energy in a short distance, can accurately kill tumor cells, and have less damage to surrounding normal tissues. However, as neutrons are scattered or absorbed when passing through media such as air, the intensity and energy distribution of the neutron beam are changed, which requires that the device for emitting the neutron beam is as close to the tumor center of a patient as possible, but the conventional radiotherapy bed cannot meet the requirement, and the distance between the device and the tumor center of the head of the patient is larger, so that the utilization efficiency and the treatment effect of the neutron beam are reduced. Disclosure of utility model The utility model aims to overcome the defect of larger center-to-center distance between neutron beam equipment and the tumor of the head of a patient in the prior art, and provides a movable therapeutic bed for neutron therapy, which enables the center position of the tumor of the head of the patient to be as close to the neutron beam equipment as possible, thereby improving the utilization efficiency and therapeutic effect of neutron beam. In order to solve the technical problems, the utility model adopts the following technical scheme: The utility model provides a movable treatment couch for neutron therapy, includes bottom plate subassembly, head support subassembly and is used for the adjustment the bottom plate subassembly with head support subassembly relative position's adjusting device, adjusting device is including setting up the regulation guide rail of bottom plate subassembly and setting are in the slip subassembly on the head support subassembly, slip subassembly with regulation guide rail sliding connection. According to the movable therapeutic bed for neutron therapy, the relative positions of the bottom plate component and the head support component can be adjusted by using the adjusting device, the head support component is adjusted to a proper position by sliding the sliding component arranged on the head support component on the adjusting guide rail on the bottom plate component, so that the center position of a tumor on the head of a patient can be close to neutron beam equipment as much as possible, and the utilization efficiency and therapeutic effect of neutron beam are improved. Further, the adjusting guide rail and the sliding component are both arc-shaped, and the adjusting guide rail and the sliding component are concentric arcs and have the same radius. The sliding assembly slides along the arc-shaped adjusting guide rail, the included angle between the head support assembly and the bottom plate assembly can be changed, and meanwhile, the circle centers of the adjusting guide rail and the sliding assembly are overlapped and have the same radius, so that the sliding assembly can smoothly and stably slide on the adjusting guide rail, and clamping stagnation cannot occur. Further, the arc length of the adjustment rail is greater than the arc length of the sliding assembly. The arc length of the adjusting guide rail is larger than that of the sliding assembly, so that the angle adjusting range between the head support assembly and the bottom plate assembly can be increased, and the treatment couch can adapt to the tumor positions of different patients. Further, a positioning groove is formed in the adjusting guide rail, a positioning protrusion is arranged on the sliding assembly, and the positioning protrusion is clamped with the positioning groove. The locating bulge on the sliding component is clamped with the locating groove on the adjusting guide rail, so that medical staff can intuitively feel the range of the included angle between the head support component and the bottom plate component in the use process, and a specific included angle can be conveniently selected. Further, the top surface and the bottom surface of the bottom plate assembly are both provided with adjusting guide rails, the sliding assembly comprises a first sliding part and a second sliding par
