Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
Fig. 1 is the schematic diagram of the Interal fixation device provided according to one embodiment of the present of invention.As shown in Figure 1, steel plate
Fixed device includes: the first steel plate 11, suture 12 and the second steel plate 13.For the first steel plate, according to Fig. 3, first steel
Plate 11 has the longitudinal axis extended along itself, and first through hole 111 and the second through-hole are distributed on the longitudinal axis
112；First steel plate 11 can have elongated, slightly rectangular shape, have circular or curved extreme ends.The
One through-hole 111 and the second through-hole 112 can be located adjacent one another, and are located so that their center is located at the longitudinal direction of the first steel plate 11
On axis.Other than embodiment shown in Fig. 3, multiple through-holes can also be set on the first steel plate 11, as a kind of specific
Embodiment further includes third through-hole and fourth hole on the first steel plate 11, and third through-hole can be positioned at 111 He of first through hole
Between second through-hole 112, and its center can deviate certain distance from longitudinal axis.First to fourth through-hole can have base
Identical aperture in sheet may be set to be the identical or all different aperture in part.
Suture extends through the first through hole of the first steel plate and second through-hole, common suture pass through line
The mode of knot is fixed, and suture length is unadjustable, and it is not convenient enough to use, simultaneously because the presence of knot, knot
It will lead to the damage of soft tissue with soft tissue friction.For this purpose, in embodiments of the present invention, suture adjustable length, one
In a specific embodiment, as shown in Fig. 2, setting has by the first open end 121 and the second open end 122 on suture 12
One end of the receiving unit of composition, the suture enters the receiving unit from first open end 121, from second opening
Leave the receiving unit in end 122.By receiving unit of the setting with frictional damping on suture, can be avoided using knot,
And the wire loop of suture composition can be adjusted according to the actual needs, improve the efficiency used.For example, the suture
12 one end is entering and leaving institute from the first through hole 111 of first steel plate 11 and second through-hole 112 respectively
After stating the first steel plate 11, the second opening 112 in suture is passed through from the first opening 111 of the receiving unit and leaves suture,
And it passes through the third opening in the suture to receive in suture.
Suture 12 can be intertexture or braided suture, and the suture uses high-strength polyester braided suture, and can
Label is distinguish to line bracing wire is taken out by the braided suture of different colours.By pulling the single free end of suture 12,
The length of the section ring of adjustable suture composition, as a kind of specific embodiment, between first through hole 111 and the second through-hole 112
The minimum value of distance can be such that suture opens the first of suture 12 using hot knife during use to about 40mm
Mouth end 121 and the second open end carry out thawing binding operation, and then prevent suture from unclamping.
In another embodiment of the present invention, one end of the suture 22 initially passes through first steel plate 21
First through hole after then passing back through the first through hole, is then passed through the second through-hole of first steel plate 21, then with suture
Second through-hole is passed back through again after 22 intersections.Suture 22 can be intertexture or braided suture, and the suture is using high
Strength polyester braided suture, and label can be distinguish to line bracing wire is taken out by the braided suture of different colours.Pass through drawing
The single free end of suture 22, the length of the wire loop of adjustable suture composition.
The Interal fixation device that the embodiment of the present invention provides further includes the second steel plate 31, the second steel according to Fig. 4
The schematic diagram of plate has the first longitudinal direction edge and second longitudinal direction edge extended along itself on second steel plate 13, wherein
It is equipped with the first gap 131 in the first longitudinal direction edge, is equipped with the second gap 132 in the second longitudinal direction edge, it is described
Suture is inserted in first gap 131 and the second gap 132 respectively.It is reliable solid in order to avoid suture is detached from the second steel plate
Fixed, first gap 131 and the second gap 132 are made of the first arc and the second arc, wherein second arc
Radius of curvature of the radius of curvature less than the first arc.
When specifically used, first steel plate 11 and the second steel plate 13 are placed in the outside of two pieces of bone of separation.First with
Kirschner wire bores a tunnel on two pieces of bones for need to install steel plate, then makes the first Interal fixation in the outer of the first bone
Side, traction suture reach the outside of the second bone, then suture is inserted in the first of second steel plate respectively by tunnel
Gap and the second gap, free end to the first bone and the second bone for tensing suture line are tightly fastened, then two separated piece bone
It can be with return.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
Present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: it still may be used
