Abstract
The invention discloses a tibia inverted intramedullary nail. The tibia inverted intramedullary nail comprises a far-end nail body and a near-end nail body which are coaxially arranged. The diameter of the far-end nail body is larger than that of the near-end nail body. The far-end nail body is provided with a first fixing hole, a second fixing hole and a third fixing hole. The first fixing hole, the second fixing hole and the third fixing hole are sequentially formed in the direction from the far-end nail body to the near-end nail body. The first fixing hole and the second fixing hole are perpendicular to the axis direction of the intramedullary nail. An 85-degree included angle is formed between the first fixing hole and the axis direction of the intramedullary nail. The second fixing hole is perpendicular to the axis direction of the intramedullary nail and perpendicular to the first fixing hole. A 55-degree included angle is formed between the third fixing hole and the axis direction of the intramedullary nail. The novel intramedullary nail is suitable for tibia calcaneus, and operations are safe and convenient.

Preferably, in above-mentioned tibia is inverted intramedullary pin, described intramedullary pin material is titanium alloy material.
Compared with prior art, it is an advantage of the current invention that: the tibia of this novel offer is inverted intramedullary pin knot
Structure is simple, safety is high, is suitable for clinical demand, and intramedullary pin tensile strength is high, can be used for tibia, calcaneus
Fusion, can realize operative incision little, purpose fast and easily of performing the operation.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present application or technical scheme of the prior art, below will be to reality
Execute the required accompanying drawing used in example or description of the prior art to be briefly described, it should be apparent that below,
Accompanying drawing in description is only some embodiments described in the application, for those of ordinary skill in the art
From the point of view of, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 show tibia in the specific embodiment of the invention and is inverted the perspective view of intramedullary pin.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out
Detailed description, it is clear that described embodiment is only a part of embodiment of the present invention rather than complete
The embodiment in portion.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation
Property work on the premise of the every other embodiment that obtained, broadly fall into the scope of protection of the invention.
Shown in Fig. 1, tibia is inverted intramedullary pin, follows closely including the far-end rivet nut 1 being coaxially disposed and near-end
Body 2, the diameter of far-end rivet nut 1 be more than near-end rivet nut 2, far-end rivet nut 1 offers the first fixing hole 11,
Second fixing hole 12 and the 3rd fixing hole 13, first fixing hole the 11, second fixing hole 12 and the 3rd is fixed
Hole 13 sets gradually from far-end rivet nut 1 to near-end rivet nut 2 direction, and the first fixing hole 11 and second is fixed
Hole 12 is perpendicular to intramedullary pin axis direction, and the first fixing hole 11 becomes 85 ° of angles with intramedullary pin axis direction,
Second fixing hole 12 is perpendicular to intramedullary pin axis direction, and the second fixing hole 12 is vertical with the first fixing hole 11,
