The invention provides a funnel chest orthotic device, which is formed by a funnel chest orthotic steel plate made of shape memory alloy materials, and a funnel chest orthotic steel plate fixator made of shape memory alloy materials, wherein the funnel chest orthotic steel plate is formed by a straight-plate shaped steel plate main body and fixed piece parts respectively arranged on two ends of the steel plate main body and provided with tooth-shaped fixed grooves; the funnel chest orthotic steel plate fixator is formed by a main beam and side beams rigidly and fixedly arranged on the main beam; a steel plate encircling arm is rigidly arranged on an external end of each side beam; and rib encircling arms are respectively arranged on two external ends of the main beam rigidly.
Description
Technical field
The present invention relates to a kind of orthopedic medical device, particularly a kind of thoracic surgery is used to treat the fixed apparatus that is implanted into of funnel chest or flail chest.
In the funnel chest therapeutic scheme; At present; The novel operation method of more and more being accepted by doctor and patient is that funnel chest is treated in NUSS ruling by law, and in this operation process, the operation doctor is in the funnel chest operation time; Use traditional NUSS steel plate and NUSS steel plate fixing head at the patient's two fix N USS of frame timber place steel plates, to prop up the breastbone that subsides.At first need be in operation with traditional NUSS steel plate through moulding pincers or lever with the bending of traditional NUSS steel plate, be that the holddown groove reuse operation suture thread that earlier orthopedic NUSS steel plate is inserted fixing head is sewn to fixing head on patient's the periosteum when fix N USS steel plate.Or directly orthopedic NUSS steel plate binding is fixed on patient's rib through steel wire.Effect in this operation directly receives doctor's proficiency level's influence, because the doctor's of different actual enforcement operations technological disparity property will cause the NUSS steel plate shape of bending in the concrete operation uneven, directly the orthopedic effect of influence; Existing fixed plate or steel wire bundle complicated operation are time-consuming simultaneously, and fixing not firm, make risk increase in the operation process, avoid internal organs as taking every caution against error with the steel wire bundle reshaping plate.On the other hand, adopt existing apparatus in operation, to require great effort during doctor's operating cost, all these have directly influenced safety, the effectiveness of NUSS steel plate fixation stability property, reliability and operation.
Summary of the invention
The present invention provides a kind of insufficient funnel breast orthopaedic device of prior art that overcomes.
Funnel breast orthopaedic device of the present invention is that the funnel breast orthopaedic steel plate holder that the funnel breast orthopaedic steel plate processed with shape memory alloy material and shape memory alloy material are processed is formed, the funnel breast orthopaedic steel plate by straight tabular steel plate main body and the two ends that are divided into the steel plate main body, have on it and can partly form with the fixture that the steel plate on the funnel breast orthopaedic steel plate holder is encircled the profile of tooth holddown groove that arm cooperates; Funnel breast orthopaedic steel plate holder is made up of girder, the curb girder that is rigidly secured on the girder, and: rigidity is provided with steel plate and encircles arm in the outer end of each curb girder, and rigidity is provided with rib and encircles arm respectively in girder two outer ends.
In a kind of funnel breast orthopaedic device of the present invention, quadrature arrangement between the curb girder of its funnel breast orthopaedic steel plate holder and girder promptly is similar criss-cross layout between its girder and curb girder; Be in tilted layout between the curb girder of another kind of funnel breast orthopaedic steel plate holder of the present invention and girder.
In a kind of funnel breast orthopaedic device of the present invention, the straight plate structure of the same axis that the fixture part at the steel plate main body in its stage casing of funnel breast orthopaedic steel plate and steel plate main body two ends is in the same plane, and the profile of tooth of fixture part serrate slot is a rectangular teeth; And in the another kind of funnel breast orthopaedic device of the present invention, fixture its axis of part and the steel plate body axis that are positioned at steel plate main body two ends tilt, and the profile of tooth of fixture part serrate slot is a rectangular teeth.
The adoptable marmem of funnel breast orthopaedic device of the present invention is a Ti-Ni marmem.
Funnel breast orthopaedic device of the present invention can be prepared multiple model according to the rib angle, to be applicable to different patients' needs.
Funnel breast orthopaedic device of the present invention in use; Between its orthopedic steel plate and rib and holder fixedly is directly to encircle arm or rib through steel plate set on the holder to encircle arm and realize; Therefore device of the present invention does not need for another example that the prior art that kind need be sutured in it on periosteum with surgical thread in concrete operation process; With fixation with steel wire reshaping plate and holder; Not only can simplify operation process, can make fixing between funnel breast orthopaedic steel plate and funnel breast orthopaedic steel plate holder, but also can reduce the risk of operation greatly than more reliable in the prior art, firm with steel wire bundle.
Biggest advantage of the present invention is to have adopted marmem to prepare funnel breast orthopaedic steel plate of the present invention and holder thereof.Because memorial alloy; Particularly has the intensity height like ti-ni shape memory alloy used in the present invention; But quality is little, have the characteristics of reminiscence original-shape; Therefore its volume of device of the present invention that manufactures than prior art littler, intensity is higher, and in operation, use can be convenient, light and handy, and can shorten operating time greatly.
Because device of the present invention has adopted the shape memory manufacturing; Therefore can prepare the most suitable funnel breast orthopaedic device of shape according to patient's concrete condition in advance; The shape that can be in advance in operation under cooling condition, it be deformed to the most suitable operation; After being fixed, suitably heating to make it return to initial shape again, imposes external force again and can realize and this recovery process need not surgical staff.Therefore device of the present invention can effectively reduce doctor's operation easier and operation complexity in can the corresponding disease of efficacious therapy, alleviates the patient suffering greatly.
