Abstract

The utility model discloses a flat bone connecting device, which comprises a fixing rod, a fixing lock and a titanium mesh, wherein the fixing rod is fixed on the crista iliaca of the ilium or the axillary margin of the scapula; as the crista iliaca of the ilium or the axillary margin of the scapula is of an irregular shape, the fixing rod can be bent randomly to adapt to the shape of the crista iliaca and the scapula during operation, and the fixing rod can be cut into any length according to the requirements of the fracture. The fixing rod is connected with the fixing lock; the fixing lock is connected with the titanium mesh; the titanium mesh can be cut and shaped randomly according to the fracture area and shape. The fixing rod is fixed on the crista iliaca of the ilium or the axillary margin of the scapula; as the sclerotin of the crista iliaca of the ilium or the axillary margin of the scapula is relatively thick, the fixing rod can be well fixed; the fixing lock which is well connected with the fixing rod is adopted, the titanium mesh is fixed on the subscapular fossa of the scapula and the fossa iliaca of the ilium, wherein the sclerotin of the subscapular fossa of the scapula and the fossa iliaca of the ilium is relatively thin; the titanium mesh is fixed randomly with small screws, the fixation and the restoration of the whole ilium and the scapula can be realized, and complications caused by poor fixation and restoration are reduced.

Description

A kind of flat bone bone-knitting device

Technical field

This utility model relates to technical field of medical instruments, be specifically related to a kind of Orthopeadic Surgery, orthopaedics in implant into body for the fixing flat bone bone-knitting device of flat bone fracture.

Background technology

Ilium and scapula are the flat irregular bones of two of human body, often because traffic accident and other external force cause comminuted fracture.Because flat bone is too thin, fracture is difficult for fixing, can only utilize a side crista iliaca of ilium and the relatively thick place of axillary margin sclerotin of scapula to carry out the fixing of reconstruction plate.But due to the subscapular fossa of scapula and the iliac fossa sclerotin of ilium poor and very thin, thickness is 0.3mm, easily fracture.When herein injured, cannot fix by the method for reconstruction plate, adopt sometimes at present titanium net to fix, when but titanium net is directly fixed on the subscapular fossa of scapula and the iliac fossa of ilium, because sclerotin is thinner, so fixing bad, easily cause titanium net to come off, fracture malunion, can produce the ill symptomses such as pain when movable.

Utility model content

Technical problem to be solved in the utility model is to hold caducous shortcoming and the flat bone bone-knitting device that a kind of fixed effect is good is provided for fixing bad and fixture of the prior art.

For solving technical problem of the present utility model, adopt following technical scheme:

A kind of flat bone bone-knitting device, comprise hold-down bars, fixing lock and titanium net, described hold-down bars is fixed on the crista iliaca of ilium or the axillary margin of scapula, because this place is irregularly shaped, described hold-down bars can arbitrarily bend to adapt to the shape of crista iliaca and scapula in art, and length can arbitrarily be mated according to the demand of fracture.Described hold-down bars is connected and fixed lock, and described fixedly lock connects titanium net, and described titanium net can be according to the iliac fossa fracture area of the subscapular fossa of scapula and ilium and arbitrarily shearing and moulding of shape.

Described fixedly lock is hinge-type, comprises installing hole, and described hold-down bars is sleeved in installing hole, and described installing hole one side is laterally flexibly connected two installing plates, in the middle of described two installing plates, titanium net is set, and the centre of described installing plate arranges fixing hole.

Described hold-down bars is for fixedly titanium is excellent.

Described hold-down bars is cuboid, and described installing hole is the square opening suitable with hold-down bars.

This utility model is that hold-down bars is fixed on to the crista iliaca of ilium or the axillary margin of scapula, because the axillary margin sclerotin of the crista iliaca of ilium or scapula is relatively thick, so realized the good fixing of hold-down bars, adopt the fixedly lock being well connected with hold-down bars that titanium net has been fixed on to the thinner subscapular fossa of scapula and the iliac fossa of ilium of sclerotin simultaneously, titanium net carries out arbitrarily fixedly having reached the fixing of whole ilium and scapula and having resetted with small screw, has reduced some complication due to fixing and malreduction.

Accompanying drawing explanation

Fig. 1 is this utility model structural representation;

Fig. 2 is the structural representation of the fixing lock of this utility model.

The specific embodiment

Below in conjunction with accompanying drawing, this utility model is described in further detail:

As shown in Figure 1 and Figure 2, a kind of flat bone bone-knitting device, comprise that hold-down bars 1, fixing lock 2 and titanium net 3. are that hold-down bars 1 adopts 3mm thick, the cuboid titanium rod that 5mm is wide, hold-down bars 1 is fixed on the crista iliaca of ilium or the axillary margin of scapula, and the shape of the crista iliaca of the bending degree of hold-down bars 1 and length and ilium and the axillary margin of scapula and length are adaptive, hold-down bars 1 is connected and fixed lock 2, fixing lock 2 comprises installing hole 4, and installing hole 4 is square opening, and hold-down bars 1 is sleeved in installing hole 4 suitable with installing hole 4.Fixing lock 2 be hinge-type, and installing hole 4 one sides are laterally flexibly connected the middle gap 7 interior installation titanium net 3 of 6, two installing plates of two installing plates 6, and the centre of installing plate 6 arranges fixing hole 5, for fixing titanium net 3.Titanium net 3 can be sheared with moulding according to the situation of the iliac fossa fracture area of the subscapular fossa of scapula and ilium.

During use, according to the situation of fracture, select the length of hold-down bars 1, the shape of then according to the shape of the axillary margin of the crista iliaca of fracture site ilium and scapula, hold-down bars 1 being carried out to the crista iliaca of bending and ilium and the axillary margin of scapula is adaptive, in the fixing lock 2 of hold-down bars 1 suit, is fixed on the crista iliaca of ilium and the axillary margin of scapula.Then according to the situation of the iliac fossa fracture of the subscapular fossa of scapula and ilium, titanium net 3 shapes are sheared with moulding, titanium net 3 is arranged in the middle gap 7 of two installing plates 6, by fixing of fixing hole 5, titanium net 3 is connected with fixing lock 2, finally with many pieces of Screws 8, titanium net 3 is fixed on to the subscapular fossa of scapula and the iliac fossa of ilium.
