Description
Technical field:
The utility model relates to a kind of radiotherapy assistive device, relate in particular to a kind of abdominal part radiotherapy localization seat.
Background technology:
Fast development along with computer technology and radiotherapy treatment planning system; radiation therapy technology also develops rapidly; 3 dimensional conformal radiation therapy (3D CRT) has successively appearred within a short period of time; radiotherapy (IGRT) under Intensity Modulation Radiated Therapy (IMRT) (IMRT) and the image guiding; these all belong to high accuracy radiotherapy; can make the dose distribution in the tumor target area more even; simultaneously can also form very steep dose gradient at edge, tumor target area; the risk organs of protection target area periphery is subjected to less or avoids radiation damage; these all be unable to do without high-precision position and fix; and general abdominal part fixed mount does not have special position fixture in the present hospital; in therapeutic process, can not guarantee the accuracy of resetting; and the size in the abdominal part radiotherapy hole on the base is fixed; can not regulate size according to different patients' practical situation, this is the existing in prior technology weak point.
Summary of the invention:
The purpose of this utility model; be exactly at the existing in prior technology deficiency; a kind of technical scheme that has the abdominal part radiotherapy localization seat of position fixture is provided; this scheme can make position accurately fixing; and can effectively protect corresponding organ injury-free; gradation pendulum position good reproducibility, position is fixing simple, convenient and practical.
This programme is realized by following technical measures: this abdominal part radiotherapy localization seat, comprise the base that has the abdominal part locating hole, be characterized in having on the described abdominal part locating hole arcual heat memory fixed body film, in described heat memory fixed body film periphery the localization and positioning chi is arranged, there is laser pendulum position instrument localization and positioning chi upper end, described localization and positioning chi is arc localization and positioning chi, be fixed with three magic crosses by connecting plate on the localization and positioning chi, scale marker is arranged on the connecting plate, patient is by heat memory fixed body film, localization and positioning chi and laser pendulum position instrument reach the accurately fixing of position, and the accuracy of repeated positioning is good, and position error is little.
Above-mentioned base comprises upper bed-plate and lower bottom base, and upper bed-plate and lower bottom base be for flexibly connecting, and when time spent not can pull down upper bed-plate, upper bed-plate can be used as common abdominal part locating rack to be continued to use.
The adjustable abdominal part framework of above-mentioned abdominal part locating hole both sides and base are for being slidingly connected; this structure can be regulated the size of abdominal part locating hole according to different patients' different figures; organs such as small intestinal, bladder are fully sunk be in from the target area than distant positions, thereby obtain favourable protection.
The fixing hole corresponding with the localization and positioning chi arranged on the above-mentioned upper bed-plate, and fixing hole can be fixing easily with the localization and positioning chi of different station.
At described abdominal part locating hole periphery scale marker is arranged, in therapeutic process, can read patient's treatment pendulum bit data easily.
In described heat memory fixed body film both sides the clamp mechanism that is mated is arranged, the clamp mechanism employing fixed knob control of this scheme fixedly fixture block clamps heat memory fixed body film.
On four angles between described upper bed-plate and the lower bottom base, an adjusting handle is arranged respectively, the point type level indicator is arranged on upper bed-plate, can regulate the levelness of positioning seat easily and show the levelness of positioning seat by the point type level indicator by adjusting handle, this structure can make treatment pendulum position more accurate, convenient.
The beneficial effect of this programme can be learnt according to the narration to such scheme; position is fixing simple, convenient in this scheme; the accuracy of repeated positioning is good; position error is little; and can effectively protect corresponding organ injury-free; positioning seat is made by carbon fibre composite, has improved the ray penetrance, has reduced the Rapid Dose Calculation error.This shows that this utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
