Abstract
The invention discloses a multidirectional locking intramedullary interlocking nail, and belongs to medical apparatuses and instruments. The far end of a main nail is provided with a front-back direction lock pin straight-passing lock nail hole A, an internal-external direction lock pin internal and external transverse pass lock nail hole B, and two internal-external direction internal and external transverse pass or 45-degree internal and external inclined pass lock nail holes C, the near end of the main nail is provided with a front-back direction lock nail front-back straight pass lock nail hole A, two 90-degree intersection, two 90-degree intersection lock nail front-internal, front-external to back-external and back-internal transverse pass lock nail holes D, two internal-external direction internal-external transverse pass or 45-degree internal-external inclined pass lock nail holes C and an internal-external direction internal-external transverse pass lock nail hole B. The multidirectional locking intramedullary interlocking nail has the advantages that the stability of the angle between the main nail and the lock nail is stronger; the near end and the far end have multidirectional locking; the high-thread cancellous bone lock pin has the surrounding, extrusion and fixing effect on a fracture of distal radius.
Description
Technical field
The invention belongs to a kind of medical apparatus and instruments, lock multidirectional intramedullary nail with lock particularly to one.
Background technology
Tibia is near, fracture of distal, particularly relates to IA Platform Fracture and pilon fracture is common joint internal skeleton
Folding, operation is treatment tibial plateau and the main method of pilon fracture, frequently with open reduction steel plate screw internal fixation, by
Fixing in non-locking steel screw being off property marrow outer support, steel plate and the fracture of offside are difficult to obtain symmetrical fixing.So it is clinical
Encircle support frequently with double steel plate or three steel plates to fix, but local soft tissue can be caused major injury by this fixed form.
The appearance of locking steel plate is a progress for the treatment of for tibial plateau fracture, its provide outside marrow relative to symmetric support fix, special
Not being complexity fracture, curative effect is reliable.But it is required to cut and separate large range of soft tissue, institute owing to steel plate screw is fixing
The soft tissue damaged is increased the weight of beyond doubt damage and brings the risk of higher postoperative infection.
Current intramedullary nail with lock is only applicable to the fracture of tibial shaft, and fracture remote for tibia, near-end is contraindication, former
Because of be the 1. at present tibia marrow nail of Clinical practice main nail and pinning between without " angle is stable " function, do not have the most each other
There is lock function；2. tibia marrow nail is near, distal locking nail hole is few, and without the multidirectional lock function of science；3. pinning itself
Not there is cancellous bone screw function, Platform Fracture is not encircled effect；4. intra-articular fracture is related to, solid in restricted locking
On the basis of Ding, still need and want non-limiting lag-screw of cancellous bone auxiliary fixing, i.e. " raft nail " fixing, make intra-articular fracture turn
For extra-articular fracture.
Summary of the invention
It is an object of the invention to overcome above-mentioned defect, it is provided that a kind of lock multidirectional intramedullary nail with lock, its main nail with
Having lock function between pinning, angle stability is higher；Closely, far-end has multidirectional locking；High screw thread spongy bone pinning opposite end bone
Folding encircles extruding fixation；Reducing soft tissue to cut and dissection scope, the blood supply outside protection marrow, correspondingly protection is subject to
The soft tissue dampened, reduces complication.
It is an object of the invention to be achieved through the following technical solutions: a kind of lock multidirectional intramedullary nail with lock, including main nail
And pinning, described main nail is shaft-like, main nail proximally and distally between be provided with bent angle forward, it is characterised in that: described master
The far-end of nail is provided with four locking nail holes, is one fore-and-aft direction locking nail hole A of distalmost end respectively, and before and after pinning, direct puncture enters locking nail hole A,
One inward-outward direction locking nail hole B of nearside, crosses locking nail hole B, middle two inward-outward direction locking nail hole Ca and Cb, pinning inside and outside pinning
Hole Ca and Cb is respectively positive water-drop-shaped and anti-water-drop-shaped, and locking nail hole Ca with Cb is oblique in main nail to be connected, the droplet-shaped that structure is at 45 °
Passage, crosses locking nail hole Ca and Cb, or tiltedly wears locking nail hole Ca and Cb in 45 ° inside and outside droplet-shaped passage inside and outside pinning；Described
The near-end of main nail is provided with eight locking nail holes, is most proximal end one fore-and-aft direction locking nail hole A, direct puncture locking nail hole A before and after pinning respectively,
Two-layer locking nail hole D thereunder, every layer of locking nail hole D include two mutual intersections in 90 ° and at 45 ° with most proximal end locking nail hole A
Locking nail hole D, pinning in the past in backward outer or front outer the most backward in direct puncture each locking nail hole D, the Liang Genei foreign side below locking nail hole D
Being respectively positive water-drop-shaped and anti-water-drop-shaped to locking nail hole Ca and Cb, locking nail hole Ca and Cb, locking nail hole Ca and Cb is oblique in main nail
Connection, the droplet-shaped passage that structure is at 45 °, crosses locking nail hole Ca and Cb, or passes inside and outside droplet-shaped passage oblique in 45 ° inside and outside pinning
Wear locking nail hole Ca and Cb；One inward-outward direction locking nail hole B of farthest side, crosses locking nail hole B inside and outside pinning.
Described proximal diameter is more than mobile jib diameter.
Described bent angle is 8 ± 3 °.
It is provided with screw thread in described locking nail hole, does not set screw thread or be partly provided with screw thread.
Described pinning is high screw thread spongy bone pinning, and rivet nut is provided with cancellous threads, and cancellous threads height is 0.2-
2.5mm, for circle shoulder pole type at the bottom of cancellous threads silk.
Pitch 1.0-4.0mm of described cancellous threads.
Diameter 2.0-6.0mm at the bottom of described cancellous threads silk, high screw thread spongy bone pinning external diameter 4.5-6.5mm.
Advantages of the present invention and providing the benefit that:
1, use spongy bone pinning, be designed as circle shoulder pole type at the bottom of it, make to have between main nail and pinning lock function, angle
Stability is higher, increases the fatigue resistance of pinning simultaneously, reduces the complication of fracture；
2, the multidirectional locking of pinning, can direct puncture, cross or tiltedly penetrate locking nail hole, form solid fixing, near, far-end locking direction
Design by the anatomic form feature of proximal tibial platform, far-end articular surface of ankle, there is the multidirectional lock function of science；
3, high screw thread spongy bone pinning opposite end fracture encircles extruding fixation；
4, lock multidirectional intramedullary nail with lock and reduce soft tissue incision and dissection scope, protect the blood supply outside marrow, accordingly
The soft tissue that ground protection is dampened, reduces complication.
5, the axle center locking multidirectional intramedullary nail with lock supports fixing, makes interior outside platform accept symmetric support power.
