Abstract
The utility model discloses a CT guiding, puncturing and positioning device relates to the medical imaging articles for use, concretely relates to CT puncture locator. Including square frame and a plurality of guide bar, be provided with the equidistant circular recess of a plurality of on the four sides of frame respectively, the one end side of guide bar is provided with the arch, and another pot head of guide bar has the lantern ring, is provided with the arch on the lantern ring equally, protruding and circular groove phase matches, four right angle departments of frame are provided with the spring leaf. The problem of the location that exists among the prior art inaccurate, positioning operation is complicated is solved.
Description
Technical field
This utility model relates to medical imaging articles for use, is specifically related to a kind of CT puncture locator.
Background technology
The laser navigation that utilizes that current CT puncture locator has positions, and costly, complex operation, is not suitable for, in basic hospital penetration and promotion, having certain limitation；Have is direct in body surface coarse localization, and the determination of anchor point relies primarily on experience and the technical merit of operator, and degree of accuracy is the highest, and error is big, and the operating time is long, easily increases the misery of patient.Chinese patent literature CN201585995U discloses a kind of CT guide puncture positioning device, and this device realizes location by plastic frame, vertical tinsel.But said apparatus positioning action is inconvenient, and position location can be moved, inaccurate.
Utility model content
This utility model provides CT guide puncture positioning device, solves and positions inaccurate, that positioning action is complicated problem present in prior art.
For solving the problems referred to above, this utility model adopts the following technical scheme that CT guide puncture positioning device, including square frame and several guide posts, four limits of frame is respectively arranged with several equally spaced circular grooves；The one end side of guide post is provided with projection, and the other end of guide post is cased with the collar, and the collar is again provided with projection；Projection matches with circular groove；Four right angle of frame are provided with spring leaf.
This utility model has simple in construction, the easy to operate and advantage of accurate positioning.

Fig. 1 is this utility model structural representation；
Fig. 2 is the left view of Fig. 1；
Fig. 3 is the upward view of Fig. 1；
Fig. 4 is guide post schematic diagram of the present utility model.
Symbol description in figure: frame 1, guide post 2, groove 3, protruding 4, the collar 5, spring leaf 6.
Detailed description of the invention
By optimal embodiment, this utility model is described in detail below。
As Figure 1-4, CT guide puncture positioning device, including square frame 1 and several guide posts 2；Several equally spaced circular grooves 3 it are respectively arranged with on four limits of frame 1；The one end side of guide post 2 is provided with protruding 4, and the other end of guide post 2 is cased with the collar 5, and the collar 5 is again provided with protruding 4；The collar 5 can be in the enterprising line slip of guide post 2.Protruding 4 match with circular groove 3；Guide post can be placed in different regions according to practical situation.Four right angle of frame 1 are provided with spring leaf 6, and this CT positioner can be fixed on human body by spring leaf 6, prevents it from sliding, and cause positioning inaccurate.
The cross section of guide post of the present utility model is circular, its a diameter of 3-5 millimeter.
Before location, leading CT transverse section scanning internal organs, after determining knub position, CT guide puncture positioning device spring leaf is fixed on tumor view field, and is directed to bar and is placed on the tumor region of CT scan for the first time.Carry out CT scan again, optimal point of puncture and lesions position is found according to the position that guide post is fixing in CT image, measure the distance between point of puncture and lump, then the scanning bed same Plane Location being placed in shown on display screen, open the guide post on CT guide puncture positioning device, with a labelling point of puncture and puncture direction, according to the labelling inserting needle on CT guide puncture positioning device, thus guide tumor puncture radio-frequency (RF) ablation.
Guide post of the present utility model can be the most fixing with frame according to practical situation, it is possible to is fixed into arbitrarily angled, has simple in construction, advantage easy to use.
It is last that it is noted that obviously above-described embodiment is only for clearly demonstrating this utility model example, and not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also cannot all of embodiment be given exhaustive.And the obvious change thus amplified out or variation still in protection domain of the present utility model among.
