Description

Button fixed knot constructs and patient fixing device that radiotherapy was used Technical Field The utility model relates to the technical field of medical instruments, in particular to a button type fixing structure and a patient fixing device for radiotherapy. Background During radiotherapy, a patient needs to be fixed on a radiotherapy bed, so that deviation of the radiotherapy position caused by movement of the patient in the radiotherapy process is avoided. At present, the radiation therapy positioning diaphragm is fixed when the patient is subjected to radiation therapy, the radiation therapy positioning diaphragm is a low-temperature thermoplastic plate, the radiation therapy positioning diaphragm can be shaped randomly after being softened, the shape of the positioning diaphragm can be adjusted according to the body shape of the patient, the positioning diaphragm is attached to the patient, and the fixing effect is better when the patient is fixed. At present, the positioning membrane is fixed on the fixed bottom plate of the radiotherapy bed mainly by adopting a mode of fastening connection and bolt positioning. When the positioning diaphragm and the fixed bottom plate are connected by bolts, the bolts are required to be locked on the fixed bottom plate one by one, and the fixing mode is complicated. When the buckle is used for connection, an operator needs to press the pulling piece on the buckle to release the clamping connection between the buckle and the jack when the buckle is pulled out from the jack. In order to facilitate the application of pressure to the plectrum by operators, the buckle is mostly arranged at the edge of the bottom surface of the fixed bottom plate, but the edge of the bottom surface of the fixed bottom plate is a visual field blind area of the operators, the operators are mostly difficult to accurately press the plectrum of the buckle once, the plectrum position of the buckle is required to be searched by fumbling on the bottom surface of the fixed bottom plate, and the problem of complicated buckle fixing mode is also solved. And when the buckle setting is in fixed bottom plate's bottom surface edge, the unblock state of buckle is difficult to the direct observation when pressing the plectrum to operating personnel, leads to the buckle to dial the fragment and split and then damage the buckle because of pressing by force easily. Disclosure of utility model The utility model aims to overcome the defect that the prior art is difficult to simply and conveniently fix a diaphragm on a fixed bottom plate of a radiotherapy bed, and provides a button type fixing structure and a patient fixing device for radiotherapy. In order to solve the technical problems, the utility model adopts the following technical scheme: The utility model provides a button fixed knot constructs, including base, insert portion and button portion, insert portion with base joint is equipped with the slot on the base, be equipped with the intercommunication on the lateral wall of slot the slot with the outside spout of base, insert portion with the slot grafting, button portion with spout sliding connection, button portion can stretch into in the slot and will insert portion follow the slot inner chamber is ejecting. When the key-type fixing structure is used, the inserting part is inserted into the slot on the base, and then the inserting part is clamped with the base, so that the fixing between the base and the inserting part is completed. When the fixation between the base and the insertion part is required to be released, an operator presses the key part, so that the key part slides in the chute towards the direction close to the slot until the key part stretches into the slot and ejects the insertion part from the inner cavity of the slot, and the clamping connection between the insertion part and the base can be automatically released in the process that the key part ejects the insertion part from the inner cavity of the slot. After the key part ejects the insertion part from the inner cavity of the slot, the fixation between the insertion part and the base is released. The insert part of the key type fixing structure is not provided with the poking piece, when the clamping between the base and the insert part is required to be released, the action of releasing the clamping between the base and the insert part can be completed by pressing the key part on the base, and the insert part can be automatically ejected from the base, so that the operation is simple and convenient. Because there is not the plectrum on the insert, consequently need not in order to be convenient for exert pressure to the plectrum and set up the fixed knot structure in the bottom of fixed bottom plate this kind of position that the operating personnel field of vision blind area, can install the base in the position that the operating personnel can see on the bottom plate to the operating personnel can be accurate press on th
