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 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
Plate includes: mainboard, several fixed jaws for being symmetrically disposed on mainboard two sides, and mainboard is equipped with screw hole, and screw hole is cone shaped countersink,
Screw hole is longitudinally arranged on mainboard and screw hole is equidistant apart from mainboard two sides, and fixed jaw end is equipped with flat contact
Plate, mainboard and fixed jaw are with a thickness of 0.8-6.5mm；Mainboard both ends are equipped with arc notch.
Above-mentioned patent is to so bone plate is improved, but it pressurizes, locking mainly relies on screw, bolt structure
The adjustment of adaptability cannot be carried out to body, screw itself can not be absorbed by the body, and the later period still suffers from second operation taking-up
The problem of.
Summary of the invention
It is non-adjustable in order to solve locking pressure existing in the prior art, and there is also asking for second operation taking-up
Topic, a kind of currently proposed absorbable rib bone connection device.
In order to achieve the above objectives, the application adopts the following technical scheme that
A kind of absorbable rib bone connection device, it is characterised in that: including matrix, the two sides of described matrix, which are provided with, encircles arm,
Described matrix upper surface is provided at least one aperture for augmenting tissue contact area, and the purpose of aperture is to increase tissue to connect
Contacting surface product, guarantees fracture site nutrition supply, the lower surface of described matrix is provided with pressured column.
The pressured column at least two.
The pressured column is tubular.
The upper surface of the pressured column is fixedly connected with the basic lower surface.
The lower surface of the pressured column is cambered surface or Wave-shaped structural.
The lower surface of the pressured column is plane.
It is short that the length ratio of the pressured column encircles arm.
It is described encircle arm be it is multiple, matrix two sides are arranged in encircles that arm quantity is identical, and the arm of encircling is vertically arranged,
And the side for encircling arm and bottom are plane.
Described matrix is arcuate structure with arm junction is encircled.
Described matrix encircles arm and pressured column as polylactic acid PLA, polyglycolic acid PGA, poly (glycolide-lactide) PGLA or poly- couples
Dioxanone PDS.
The advantages of the application, is:
1, the application use pressured column structure the strength and stiffness of matrix are enhanced, and pressurize rod structure with
Matrix can be to be fixedly connected, so that its is more convenient to use, not need additional tool and operation.Memory in the prior art
Alloy type rib cage girdle device needs to freeze and dedicated dilator, and the application does not need specific purpose tool and specially treated and can install
It uses.
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 pressurization rod structure of the application is simple, directly applies pressure to human body, and will not occur at human contact
Sliding, enables bone fracture device to be preferably fixed on the rib cage of human body.
Detailed description of the invention
Fig. 1 is the application structural schematic diagram.
In attached drawing: 1- matrix 2- encircles arm 3- pressured column.
