Technical field
The present invention relates to field of medical article technology, more specifically to a kind of flexible radio-contrast grid.
Background technique
In clinical practice work, the foreign matter in most of body limbs can be developed by x-ray fluoroscopy, and preoperative pass through X
The Fluoroscopy location of light, by foreign body when can facilitate operation.Operative doctor is performed the operation according to the Position Approximate of X-ray, so
And the institutional framework of partes corporis humani point is different, level is different, and preoperative X-ray is only capable of providing the probable ranges of foreign matter, Wu Fajing
Position is determined, so that the operation has certain difficulty.Most of the time, doctor needs to have an X-rayed repeatedly to determine foreign matter in art
Position, and need to expand wound to expand search area, to increase the Accessory injury of patient, while increasing doctors and patients'
The health of doctor and patient is endangered at radiation exposure position.
Existing preoperative location technology, with good grounds wound tunnel expand notch and using the modes such as object positioning that can develop.
It is in the prior art usually to make hard metal grid in the preoperative for development positioning, since the tissue site of human body has more
There is certain radian, therefore the hard metal grid can not be preferably bonded with the tissue site of human body, is easy to make in projection
At the change of mesh shape, so that certain deviation occurs in projected position, and then the accurate positionin to foreign matter is influenced, give hand
Art causes certain difficulty.

Development character is provided on the weft of second flexible wires layer one end.
Preferably, the first flexible wires layer include at least two with one heart and the circumference that is gradually increased of radius, described the
Two flexible wires layers include at least two and arise from the center of circle and the finally radial line of the outermost circumference of the first flexible wires layer, and
The circumference is staggered with the radial line.
Preferably, the circumference equidistantly distributed, and the radial line is uniformly distributed in a circumferential direction.
Preferably, it is provided on the outermost circumference of the first flexible wires layer corresponding with the radial line
Develop angular marking, and development radius mark corresponding with the circumference is provided in zero degree radial line.
Preferably, a kind of flexible wires and the two classes flexible wires are development galvanized wire.
Preferably, the diameter of the development galvanized wire is 0.5mm-1mm.
Flexibility radio-contrast grid provided by the invention, a kind of flexible wires and the second flexible wires of the first flexible wires layer
Two class flexible wires of layer are staggered, and are fixedly connected at staggeredly position, to ensure that the shape and structure of development grid itself
And the size of each grid.Further, since a kind of flexible wires and two class flexible wires of composition line layer are flexible materials, compare
Development grid in original hard metal material, the application can preferably be bonded tissue knot in use
Structure to improve the accuracy of development positioning, and then improves the efficiency that operation carries out.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Figure 1 to Fig. 4, flexibility radio-contrast grid provided in an embodiment of the present invention, including the first flexible wires layer 1
With the second flexible wires layer 2, the two class flexible wires in a kind of flexible wires and the second flexible wires layer 2 in the first flexible wires layer 1 are interlocked
Setting, and the staggeredly position of the two is fixedly connected, to ensure that the shape and structure and each grid of development grid itself
Size.In the specific embodiment of the application, above-mentioned flexible wires preferably development galvanized wire, and the diameter for the galvanized wire that develops is
0.5mm-1mm.In actual production, the material of flexible wires can specifically be set according to production and process requirements, not done here
It is specific to limit.It is understood that diameter preferred scope is 0.5mm-1mm when flexible wires are selected as development galvanized wire, including
0.5mm and 1mm, specific diameter value are selected according to actual needs；And when flexible wires are selected as other materials, numerical value can be again
Setting, it is not limited to above range.
In the specific embodiment of the application, the first flexible wires layer 1 includes at least two warps, the second flexible wires layer 2
Including at least two wefts, and warp and weft are criss-cross, i.e., each development grid cell is rectangle.Preferably,
Above-mentioned warp and weft are disposed as equidistantly distributed, and each development grid cell is square structure at this time.It is, of course, also possible to
The form being gradually increased is set by the distance between adjacent warp according to actual needs, and the distance between adjacent weft is also provided with
It is specific as shown in Figure 2 to be gradually increased.Suitable portion on grid can be selected according to the size of foreign matter in the course of surgery
Position is positioned, and the orientation range of grid cell can also be reduced by the position of mobile grid in positioning, thus more
Accurately positioning foreign matter.The modification that thinking based on above-mentioned warp and weft setting form is made, in the protection of the application
In range.
In addition, corresponding development character can also be arranged on development grid, each grid is made to be corresponding with specific coordinate bit
It sets, so as to more accurately be positioned to foreign matter.Specifically, can 1 one end of the first flexible wires layer warp and with warp
The setting development character positioned at the weft of 2 one end of the second flexible wires layer on that the endpoint of line is connected, and the warp and weft are connected
Endpoint is the coordinate origin of character coordinates.Certainly, it is also feasible for being arranged in remaining position.
In another embodiment of the application, the first flexible wires layer 1 includes at least two with one heart and radius is gradually increased
