Description
Technical field
The auxiliary fixedly armarium of position when this utility model relates to radiation therapy subject incidence clinically refers to a kind of incidence radiotherapy body position fixture that can two-way continuous adjusting particularly.
Background technology
At present, radiotherapy section of hospital and oncology are when radiation therapy subject head and neck position, employed incidence body position fixture is formed by plurality of cuboid and triangle body unit construction mostly, its vertical adjusting parallel with human body is that the triangle body by one group of isolating cuboid and different angles makes up and realizes, separate separating between its scapulet and the head splint.There is following defective in the incidence body position fixture of this combinative structure: at first be the needs that can not satisfy the vertical luffing angle of continuous adjusting patient's incidence, next is that medical personnel must select for use different parts to make up according to different concrete conditions, and operating wastes time and energy.In order to address the above problem, incidence body position fixture selection head splint one end that also has is fixed, the other end is regulated by two arc support bars and give localized structure with bolt, though can realize the continuous adjustment of the vertical luffing angle of incidence like this, but two poles protrude on the retainer body, radiotherapy group are existed the dangerous hidden danger of causing injury.Simultaneously, existing various types of incidence body position fixtures are all less than the lateral adjustment with respect to human body, and need carry out multi-faceted adjusting according to patient's situation when carrying out radiotherapy, bring suitable inconvenience for thus patient's treatment, even have influence on radiocurable effect.
Summary of the invention
The purpose of this utility model will overcome above-mentioned existing in prior technology defective exactly, develop a kind of simple in structure integrated, can two-way two dimension regulate continuously and easy to operate, time saving and energy saving incidence radiotherapy body position fixture.
For realizing this purpose, the incidence radiotherapy body position fixture that this utility model is designed, include a fixed base plate, the movable regulating plate that is furnished with in parallel on half position of described fixed base plate, the side that described movable regulating plate is positioned at the fixed base plate middle part is provided with bracing frame, be hinged with head splint by horizontal rotating shaft on the support frame as described above, bolster is installed above the described head splint, the stationary wedge piece is installed below the described head splint.Be provided with gathering sill above the described movable regulating plate, be provided with the slip wedge in the described gathering sill, described stationary wedge piece and movable wedge match and finish vertical angular adjustment of described head splint.The vertical limit of one side of described movable regulating plate is provided with vertical rotating shaft, described vertical rotating shaft is inlaid on the support clamp on the respective side of described fixed base plate, be provided with air bag between the opposite side of described movable regulating plate below, vertical limit and the described fixed base plate, utilize the gas that charges and discharge of described air bag to finish the lateral angles adjusting that is installed in the head splint on the movable regulating plate.The fixing scapulet that has been in tilted layout with it on second half position of described fixed base plate, described fixedly scapulet is corresponding consistent with the two horizontal side height that head splint is positioned at the fixed base plate middle part.
Advantage of the present utility model is: designed head splint on bracing frame, can rotate up and down around bracing frame by its horizontal rotating shaft; Designed stationary wedge piece and movable wedge between head splint and movable regulating plate matches, and can guarantee head splint in the luffing angle of needs location, thereby makes head splint carry out the continuous adjusting of arbitrarily vertical angle with respect to fixing scapulet.Designed air bag between movable regulating plate and fixed base plate, can to make movable regulating plate be inlaid in vertical rotating shaft of supporting in the clamp with it be that the center swings by a small margin by charging and discharging gas, thus make the head splint that is installed on the movable regulating plate realize the continuous adjusting of any lateral angles.And each parts of the present utility model organically are combined as a whole, and it is simple and reliable for structure, and are easy to operate easy.Simultaneously the fixing the most key bolster of head is positioned at the top that other regulate parts, the patient is safe and reliable, the slotting hidden danger of hindering of having avoided stabbing.
