Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is that the present invention installs the position view on the C type arm X-ray perspective machine;
Fig. 3 is that the K of Fig. 1 is to view.
Labelling is as follows among the figure: the outrigger cover 7 of X line emission source bulb or image amplifier 1, photographic head 2, swing arm 3, balance staff 4, motor 5, variator 6, X line emission source bulb or image amplifier, C type arm 8, protective cover 9.
The specific embodiment
The present invention is a kind of C type arm X-ray perspective machine that external pick-up device is arranged, and it is made up of C type arm, X line emission source bulb and image amplifier, and it also has outside photographic head 2 and positioner.Photographic head 2 adopts one or more in the present invention, and they are installed simultaneously or optional one is installed in the X line emission source bulb end and the image amplifier end of C type arm X perspective ray machine.Its effect is after the X line perspective work of C type arm is finished, and gathers dynamic image in the surgical field of view by the present invention.The doctor is under the guide of image, and just the particular location of all-the-way tracking operating theater instruments in real time helps the doctor to finish operation technique better.
The positioner of photographic head 2 of the present invention can be taked multiple scheme, and a kind of is to adopt not influence the material making support that the X line sees through, and support is fixed on the front end face of X line emission source bulb end or image amplifier end, photographic head 2 is fixed on the support again.Another kind be bottom surface with X line emission source bulb end or image amplifier end as positioner, perforate embeds photographic head on the bottom surface, or photographic head is adhesively fixed on this bottom surface.In above-mentioned these two kinds of schemes,, just can not influence the perspective of X line if the volume of photographic head 2 is enough little.And if photographic head 2 volumes that adopt are bigger, then these two kinds of schemes are with regard to defectiveness, but these two kinds are adopted support bracket fastened schemes should belong to protection scope of the present invention.The invention allows for the positioner scheme of another kind of removable photographic head 2, the positioner that in this scheme, adopts swing arm 3 and swing arm drive device to form.
Show among the figure that swing arm 3 and swing arm drive device are fixed on X line emission source bulb end or image amplifier end face on patient's bottom surface with the photographic head in the image unit 2 when taking optical imagery; And when carrying out X line pivot operation, photographic head 2 is shifted out from the bottom surface, do not influence normal X line pivot operation.Concrete structure is, photographic head 2 is fixed on an end of swing arm 3, the other end of swing arm 3 has balance staff 4, balance staff 4 is installed on the outrigger cover 7 of X line emission source bulb or image amplifier, balance staff 4 is connected with swing arm drive device, swing arm 3 around the plane of balance staff 4 swing on the bottom surface of image amplifier and X line emission source bulb and parallel with this bottom surface.
The present invention is installed in the X line emission source bulb end or the image intensifier end of C type arm X perspective ray machine, and the photographic head that every end is installed is one or more, and the embodiment shown in the figure is that every end is installed one.Show among the figure that photographic head 2 has two position of rests in the movement locus of swing arm 3.The one, the center of circle of bottom surface, the one, the periphery of bottom surface.When C type arm 8 carried out the X perspective, photographic head 2 moved and rests on the periphery of bottom surface, does not produce the effect of blocking to the X line.After C type arm 8X perspective finished, photographic head 2 moved and rests on the center of circle of bottom surface, the image acquisition in the zone that undergos surgery.For guaranteeing that photographic head 2 accurately stops at the position in the center of circle, bottom surface, balance staff 4 should accurately equate with the distance of balance staff 4 to image amplifier or X line emission source bulb center to the distance at photographic head 2 centers.
Show among the figure that swing arm 3 is elongate in shape that radian is arranged, the radian of swing arm 3 is consistent with the bottom surface circumference radian of bulb end or image amplifier end, and the operation angle of swing arm 3 from the center of circle to the circumference is 60 degree.One end of swing arm 3 is swing arm drive device, and swing arm drive device comprises motor 5, variator 6 and controller, the motion mode of motor 5 received signals control swing arm 3.
Show among the figure because photographic head 2 partial distance operative regions are very near, the pollution problem in the operation, the present invention also has a transparent roentgenolucent protective cover 9, with photographic head 2 and positioner protection in the inside.
Below be the use of the present invention in distal tibial intramedullary nail with lock distal locking nail implantation surgery:
Step 1: need to determine the general location of perspective earlier with camera head, start the position that C type arm X line machine is determined perspective dowel pin hole again.
Step 2: after step 1 was finished, X line emission source quit work at once, and camera head starts once more, and swing arm moves to position, the center of circle by the circumference position, and photographic head to the center of circle, begins to gather dynamic image by circular motion.Computer shows the image that processing matches in high-resolution medical imaging display.
Step 3: under the image guiding of display, operative doctor finds locking nail hole transmission position to pierce Kirschner wire, as guide needle, changes the drill bit reaming with it again into, screws in pinning at last.
