Description
Technical field
It is specifically a kind of for the positioning at fracture of rib position, synthetism and fixed guarantor this application involves medical instruments field
The absorbable rib bone connection device of the pressure adjustable of shield.
Background technique
It is generally fixed etc. using wire binding, Kirschner wire fixation, Interal fixation and memorial alloy in thoracic surgery at present
Technology.Wire binding is difficult to control the binding dynamics of steel wire due to the tension of lung's respiration.The too loose of binding does not have admittedly
Fixed effect, binding it is too tight, be easy to make steel wire fracture, longitudinal steel wire is easy to tear in rib cage, and steel wire easily loosens, and causes rib cage
The serious adverse consequences such as poor healing, healing delay, and after breastbone healing, steel wire is also not easily taken out, and may be damaged to rib
Vitals under bone, lead to malpractice.Stainless pin is only applicable to Percutaneous pin fixation fracture, does not usually accomplish that dissection is multiple
Position, and be not fixed firmly by being easy the withdraw of the needle, lead to fixed failure.Interal fixation is more firm, but is easy to happen cell reaction, and needs
Second operation is wanted to take out steel plate；The fixed pressurization dynamics of memorial alloy can not adjust, and when operation need to strut memorial alloy, operate numerous
It is trivial, increase operating difficulty, and second operation is needed to take out.
Existing patent such as Patent No. CN 201410593822.5, applying date 2014.10.29, a kind of entitled " ring
Embrace type metal bone fracture plate " patent of invention, technical solution are as follows: the present invention relates to a kind of encircle type metal bone fracture plate, the synthetisms

The band is banded structure, and the banded structure is located at below matrix.Band sheet is as with flexible band
Shape structure, attached drawing be shown as band across locking hole be banded on rib cage after appearance.
Described to encircle arm at least two, the arm of encircling is separately positioned on matrix two sides, and every side encircles arm quantity
Identical, the arm of encircling is vertically arranged, and the side for encircling arm and bottom are plane.
Described matrix encircles arm, locking hole and band as polylactic acid PLA, polyglycolic acid PGA, poly (glycolide-lactide) PGLA
Or polydioxanone PDS.
The direction of first fixed tooth and the second fixed tooth is arranged to band by can only be from fixing end to locking after locking hole
End pulls, and is reversely automatically locked.The length of locking hole is pulled out by band locking end to adjust pressurization dynamics.Band at least two
Item is located at matrix both ends.In order to reinforce locking effect, or when fracture face is wider, it can choose and use a plurality of band.It removes
Two of matrix both ends are set to, others can according to need any position for being set to matrix side.
The advantages of the application, is:
1, the structure that the application uses that locking hole and band are mutually locked enhances the strength and stiffness of matrix, and
And band structure can be connected with each other with matrix, the pressure between matrix and rib cage can be adjusted according to different situations
Section, it is very convenient.The application does not need additional tool and operation, and such as memorial alloy class rib cage girdle device in the prior art needs
Freeze with dedicated dilator, and the application does not need specific purpose tool and specially treated and can install and use.
2, each structure of the application has been all made of the absorbable material of human body, as polylactic acid PLA, polyglycolic acid PGA,
Poly (glycolide-lactide) PGLA, polydioxanone PDS etc., so the application can be absorbed by the human body completely, without progress
Second operation is drawn off.
3, the band of the application is banded structure, and the shape for allowing band to cooperate matrix is more bonded connecing for rib cage
Bone.
4, the fixed tooth of the first of the application and the second fixed tooth can carry out elastic adjusting according to different situations, thus
Realize the adjusting of pore size between band and matrix.
Detailed description of the invention
The position Fig. 1 the application structural schematic diagram.
In attached drawing: matrix 1 encircles arm 2, link block 3, locking hole 4, band 5, fixing end 6, locking end 7.
