Description
Technical field
This utility model belongs to medical devices, relates to a kind of device of adjustable digital subtractive angiography operating-table immobilized patients head.
Background technology
DSA(digital subtraction angiography) be the angiographic method being carried out associated image by electronic computer, when doing cerebral vessels radiography, patients head is needed to maintain static, otherwise the drift of head blood vessel image, cause blood vessel image unclear, affect the judgement of doctor to the state of an illness.If repeatedly irradiate and the radiation exposure dose of patient, the intake of contrast agent can be increased, unnecessary injury is caused to patient.But it is undesirable to there is patients head's braking effect in current aforesaid operations process, and range of application is less, can not meet actual needs.
Summary of the invention
The purpose of this utility model is to solve prior art Problems existing, provides structure simple, easy to use, avoids the device of a kind of adjustable digital subtractive angiography operating-table immobilized patients head causing head blood vessel image to drift about because of head oscillation.
The technical scheme realizing this utility model object is: the device of adjustable digital subtractive angiography operating-table immobilized patients head, it is characterized in that: be provided with an offside groove in head plate of operating table lateral symmetry, groove bottom side, side, by its female thread, is fixed by bolts to bottom head plate of operating table; Head plate of operating table two upper lateral part is plugged with vertical plate by the jack on the groove of side, and vertical plate is fixed on head plate of operating table by the side groove of head plate of operating table both sides by bolt; In annular, retaining ring is on hexagonal (hexagon)nut, and it is integral with vertical plate, square screw rod one end is connected as a single entity through the spacing square opening on vertical plate and the arc-shaped limit fixing head inside vertical plate, the other end is connected with hexagonal (hexagon)nut, hexagonal (hexagon)nut smashs rotation in annular, under spacing square opening effect on vertical plate, force the spacing square opening translation of square screw rod on vertical plate, thus drive the translation of arc-shaped limit fixing head; Medical latex protective layer is pasted with inside described arc-shaped limit fixing head; Be fixed on the long frenulum on square opening that side arc-shaped limit fixing head has, can after-tack through square opening on opposite side arc-shaped limit fixing head and be attached on long frenulum.
This utility model has following substantive distinguishing features, marked improvement and positive effect:
1) device of this utility model adjustable digital subtractive angiography operating-table immobilized patients head, forms with plastic processing, does not have metal parts, do not affect image effect.Technical Design is reasonable, simple for structure, easy to use.
2) before enforcement angiography, patients head is fixed.Two pieces of arc-shaped limit fixing heads are in a temporo side (being positioned near the temple of ear side) to rear pillow part; Be fixed on the long frenulum on the arc-shaped limit fixing head square opening of side, can after-tack through opposite side arc-shaped limit fixing head square opening and be attached on long frenulum.Can effectively prevent patients head from swinging, complete angiography, make clear picture, reduce the misery of patient.
3) by the spacing between the arc-shaped limit fixing head inside vertical plate on the upper side groove of adjustment head plate of operating table both sides, and by regulating the height of the vertical plate on the side groove of both sides, head plate of operating table top, regulate the height of arc-shaped limit fixing head, two pieces of corresponding arc-shaped limit fixing heads are made to be in patients head's temporo side to rear pillow part, paste with long frenulum again, to realize fixing the spacing of different patients head, thus be suitable for most of patients, expand range of application.
4) the interior retaining ring of annular is on hexagonal (hexagon)nut, and it is integral with vertical plate, hexagonal (hexagon)nut smashs rotation in annular, square screw rod one end is connected as a single entity through the spacing square opening on vertical plate and the arc-shaped limit fixing head inside vertical plate, the other end is connected with hexagonal (hexagon)nut, and hexagonal (hexagon)nut smashs rotation in annular, under the spacing square opening effect on vertical plate, force the spacing square opening of square screw rod on vertical plate can only translation, thus drive the translation of arc-shaped limit fixing head; Be pasted with medical latex protective layer inside arc-shaped limit fixing head, this layer of softness, makes patient comfort, effectively avoids face to scratch.
5) for preventing cross infection, on two pieces of arc-shaped limit fixing heads of correspondence, cover has cloth cover, after using after sterilization, all can recycle.
