Abstract
The invention relates to a porous external fixation frame of a poly(ether-ether-ketone) composite material, which consists of a metal bone pin and an external fixation frame. A plurality of through holes are formed on an external fixation frame body made of the poly(ether-ether-ketone) composite material, and one or more concave channels are formed at the middle part of the external fixation frame body. The porous external fixation frame has the following advantages and positive effects: 1) the structure is simple, the operation is convenient, the popularization is easy, an ordinary orthopedist can quickly master and skillfully apply the porous external fixation frame, and the operation time can be greatly shortened; 2) the porous external fixation frame can be operated repeatedly and cause light damage to normal tissues and has few postoperative reactions; 3) the range of applications is wide; 4) the fixation is firm, and the porous external fixation frame is transparent and can be used for film-making, thereby facilitating the observation of intraoperative situation and postoperative fracture healing situation; 5) the disinfection method can be selected arbitrarily; and 6) the price is low.
Description
Technical field:
The invention belongs to a kind of medical apparatus and instruments, particularly a kind of porous external fixer that is used for externally carrying out the polyether-ether-ketone composite material of fracture fixation.
Background technology:
Can access reliable fixing after making the reduction of the fracture, the existing external fixator that adopts both at home and abroad is as the non-operative treatment apparatus of fracturing.External fixator carries out external fixation by wearing metal bone draw point and rigidly fixing part outward to fracture.The external fixator major structural types of clinical practice both at home and abroad has at present: 1, monoplane formula or frame-type.It is simple in structure, easy to use, but fixed poor stability, easy osteoclastic robustness.2, ring type or semi-ring slot type.Though the external fixator of this structure is firm to fracture fixation, complex structure, weight is big, manipulate complexity.And the external fixator suitability of these two kinds of structures is relatively poor, and nest is only limited to a certain position, acts on singlely, and needle track does not have the prevention infection measure.
Summary of the invention:
Purpose of the present invention just is to overcome above-mentioned the deficiencies in the prior art, and a kind of porous external fixer of polyether-ether-ketone composite material reliable, applied widely simple in structure, easy to use, fixing is provided.
Technical scheme of the present invention is: a kind of porous external fixer of polyether-ether-ketone composite material, form by metal spicule and external fixer, it is characterized in that: have several through holes on the external fixation support body of making by polyether-ether-ketone composite material, and the fixing bracket body middle part has one or multi-channel recessed road outside.
The diameter of above-mentioned through hole can be identical, also can be different.
The recessed road that has on the above-mentioned external fixation support body can be together, also can be multiple tracks.
The present invention has following advantage and good effect:
1, simple in structure, easy to operate, be easy to promote.For the normal aggregates doctor, can grasp rapidly and skillfully use.Shortened operating time widely.
2, have operability repeatedly, light to normal tissue injury, after-operation response is few.
3, the scope of application is wide.At a plurality of positions and different angle inserting needles.Can generally be used to point, the fixation of fractures of each different parts of whole body such as upper limb, lower limb, be the ideal external fixation therapeutic device in bone injury field such as extremity fracture is fixing and bone is damaged, bone does not connect.
4, fixation.Can printing opacity film making, be convenient to observe in the art and the union of fracture situation of postoperative.
5, disinfectant method can be selected arbitrarily.
6, cheap.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
As shown in the figure: a kind of porous external fixer of polyether-ether-ketone composite material, form by metal spicule 1 and external fixer 2.Have several through holes 3 on the external fixation support body of making by polyether-ether-ketone composite material, and external fixation support body middle part has one or multi-channel groove 4.The diameter of above-mentioned through hole can be identical, also can be different.
Structure of the present invention is to have numerous apertures of different-diameter to be distributed on the product, the metal spicule of different-diameter can pass and be fixed in the aperture of respective diameters according to the needs of fracture, the metal spicule is fixed on the bone piece of fracture again, make the bone piece of fracture line both sides relatively stable, played the fixedly effect of fracture.And the groove on the product makes product become the sheet of two connections, in the time of can making the metal spicule pass product, can easily pass corresponding hole, again certain frictional force can be arranged, hole on having increased up and down two is to the hold of metal spicule, thereby strengthened the fixed effect on product of metal spicule.
The present invention all adopts is the most novel a kind of extraordinary composite at present---polyether-ether-ketone resin the polyether-ether-ketone of certain proportion carbon fibre (or be mixed with), this material is the classic nonmetallic materials of at present universally acknowledged performance brilliance, is that the ideal of alternative metals is selected.And structurally adopt the porous trough of belt, cooperate traditional metal spicule to finish to fixation of fractures.
The advantage of this material is:
1, light specific gravity and intensity is big, high temperature resistant, high pressure. Also can tolerate the exposure that surpasses 109 rads and do not become fragile, and can see through X ray (can see through ray).
2, elastic modelling quantity and skeleton approach, and have eliminated the stress shielding that therefore produces, and have accelerated the healing of fracture.
3, having the most excellent combination property, is the desirable substitution material of metal at present, is widely used in aviation, ocean, medical treatment and commercial Application.
Claims (3)
1. the porous external fixer of a polyether-ether-ketone composite material, form by metal spicule and external fixer, it is characterized in that: have several through holes on the external fixation support body of making by polyether-ether-ketone composite material, and the fixing bracket body middle part has one or multi-channel recessed road outside.
2. the porous external fixer of polyether-ether-ketone composite material according to claim 1, it is characterized in that: the diameter of above-mentioned through hole can be identical, also can be different.
