As preferred version of the present utility model, at least one in-line semiconductor laser is fixed on the bulb end wedge shape inclined wall of C type arm X-ray machine.

Another is preferred as of the present utility model, described in-line semiconductor laser comprises fixed block, laser head, bundle tabula rasa and printing opacity dust excluding plate, described fixed block is a U-shaped, and described laser head is embedded in the U-lag of fixed block, transmitting terminal at laser head sets gradually bundle tabula rasa and printing opacity dust excluding plate from inside to outside, offers " one " word bundle light slit on opaque described bundle tabula rasa.

Another is preferred as of the present utility model, and described laser head emitted laser is that wavelength is the red laser of 635nm.

Another is preferred as of the present utility model, and described bundle tabula rasa is a black plastic-aluminum sheet, and described bundle light slit width is 1mm.

As of the present utility model further preferred, adopting dc source is two in-line semiconductor laser power supplies.

Further, described dc source is No. 5 rechargeable batteries of three joints, and battery places the on-off control box, and the on-off control box is fixed on the position of being convenient to medical worker's operation on the frame, and cable is pricked with line along first wife's cable of C type arm and fixed on it.

The beneficial effects of the utility model are: its processing technology is simple, and with the original equipment one integrated mass, cost is low, and for hospital has saved substantial contribution, and clinical result of use is good, accurate positioning.

Description of drawings

Below in conjunction with drawings and Examples embodiment of the present utility model is described further:

Fig. 1 is the structural representation of this utility model one embodiment;

Fig. 2 is cross laser beam locating effect figure;

Fig. 3 is the structure for amplifying sketch map of yi word pattern semiconductor laser one embodiment;

Among the figure: 1 yi word pattern semiconductor laser, 2 bulb end wedge shape inclined walls, 3 bulb ends, 4C type arm, 5 on-off control boxes, 6 image reinforcement plates, 7 laser beam projection joints, 8 laser heads, 9 bundle tabula rasas, 10 printing opacity dust excluding plates, 11U shape groove, 12 fixed blocks.

The specific embodiment

As shown in Figure 1, an embodiment of this C type arm X-ray machine laser locating apparatus comprises: comprise C type arm 4, be respectively bulb end 3 and image reinforcement plate 6 at the two ends of described C type arm 4, also comprise font semiconductor laser 1 one to one, two described in-line semiconductor lasers 1 all are fixed on the bulb end 3 of C type arm 4, and 1 emitted laser face of two in-line semiconductor lasers drops on the image reinforcement plate 6 after intersecting, form " cross " position line, the center of being somebody's turn to do " cross " position line overlaps with described image reinforcement plate 6 centers, and the initiating terminal of described meld line is on the line at image reinforcement plate 6 centers and bulb end 3 centers.

As shown in Figure 2, because the laser of Laser emission is trapezoidal shape on the surface of emission, two laser instrument emitted laser are at the cross section across of intersection, only could use laser cross positioning function to the part between the image reinforcement plate 6 at projection joint 7, in order to increase the scope of application of laser locating apparatus, need to increase the angle of laser head and centrage (lines at bulb end 3 centers and image reinforcement plate 6 centers), so that make two laser joints 7 more near bulb end 3.For solving this technical problem, make a described in-line semiconductor laser 1 be fixed on the bulb end wedge shape inclined wall of C type arm 42, cooperate the inclination angle of inclined wall to make described in-line semiconductor laser 1 emitted laser also have certain inclination angle.
