Description
Technical field
This utility model relates to medical device, particularly relates to a kind of biological absorbable and degradable blade plate.
Background technology
What at present, both at home and abroad the big multi-section of biodegradable body implant adopted is the fixing means and the appearance design of traditional titanium plate, silk thread and stainless steel silk.As shown in Figure 1, but people's implants in vivo baffle 1 ' adopts people's implants in vivo can absorb fixedly skull surface of nail 2 '.Be difficult in operation that damaged situation reparation is moulded the shape that matches with the bony surface shape according to bone.
And existing biological absorbable and degradable blade plate is adopted mostly has plenty of planarized structure, is exactly two-dimensional structure.In operation that the surface smoothing arc shape of the nearly skull of its bending forming is relatively more difficult.And easily rupture when being shaped.Periphery is also wrinkling easily, the bad control of angle of bend.Outward appearance is undesirable after causing cranium jaw face to be repaired, and the scalp that can wear and tear when serious causes subinfection again.
The absorbable and degradable blade plate needs the degradable screw to be fixed in skull surface simultaneously, because blade plate is a planarized structure, the part of screw is exposed at the blade plate outside, is very easy to the wearing and tearing scalp.Also have a kind of way, in blade plate, pour the nail sedimentation hole into.Thereby form an integral planar, but this structure fractures when product is moulding easily.Especially when its angle of bend is big, can occur potential local weak.
The utility model content
The technical problem that this utility model mainly solves provides a kind of biological absorbable and degradable blade plate, can improve the safety that biological absorbable and degradable blade plate uses, and alleviates the patient suffering.
For solving the problems of the technologies described above, the technical scheme that this utility model adopts is: a kind of biological absorbable and degradable blade plate is provided, described blade plate is the chute tower structure, comprise bottom land, parallel double track chute edge, bottom land both sides, described bottom land has a plurality of screw holes, and the bottom land between the described screw hole connects by organization framework.
The beneficial effects of the utility model are: be different from that screw exposes the situation that causes wearing and tearing skin in the blade plate outside in the biological absorbable and degradable blade plate of prior art, this utility model is designed to the chute tower structure with blade plate, screw hole is located at bottom land, can guarantee that screw is when implanting, the head of a nail is arranged in groove, the head of a nail can be submerged in the chute frame-type blade plate fully, and the head of a nail can not produce friction with skin such as scalp and cause skin wearing and tearing, the problem of subinfection again.

The specific embodiment
Consult Fig. 2 and Fig. 3 together, the biological absorbable and degradable blade plate 1 of this utility model is the chute tower structure, comprise the parallel double track chute of bottom land, bottom land both sides along 12, described bottom land has a plurality of screw holes 13, and the bottom land between the described screw hole 13 connects by organization framework 14.
Consult Fig. 3 and Fig. 4, can adopt screw 2 that blade plate 1 is fixed on the bone, screw 2 head of a nail tops are not higher than described groove along 12 height.
Be different from that screw 2 exposes the situation that causes wearing and tearing skin in blade plate 1 outside in the biological absorbable and degradable blade plate 1 of prior art, this utility model is designed to the chute tower structure with blade plate, has following technique effect at least:
1. the chute Frame Design can reduce the probability of touching with scalp, and is easy to determine the upper marginal position of framework in implantation process;
2. the chute framework strengthens the conduction of nail-plate contact surface and then optimization carrying, when saving resources costs, strengthens load capacity on the contrary;
3. straight appearance profile provides higher general stability;
4. this utility model is compared with traditional metallic object implants, need not remove blade plate, and noiseless to imaging diagnosis, implant does not have displacement; Compare with traditional absorbed implant, the utlity model has biological tissue's intermiscibility easy and simple to handle, higher;
5. the frame-type design meets and exceeds the mechanical strength of surface plate in engineering mechanics, the osteoporosis of effectively avoiding stress shielding to cause, thus adopt frame structure to have enough constant intensities, and have suitable absorption rate.
Also consult Fig. 2, in a further embodiment, described bottom land is provided with perpendicular to the double track chute along the cross-section groove 11 of a plurality of hollow outs of 12.
Wherein, cross-section groove 11 and sliding-rail groove are 90 degree along 12 junction point, can form the mechanical strength of the stability and the frame structure of right angled triangle, sliding-rail groove along 12 from another perspective, the pillar that cans be compared to the house, cross-section groove 11 cans be compared to crossbeam, it also will keep the stable frame structure of triangle when how to bend to other any shape according to the needs of performing the operation, its mechanical strength can not change, to strengthen on the contrary, this point is relevant with Biodegradable material, mouldingly will make material production self-reinforcing effect.
In addition, the cross-section groove 11 between adjacent can be strengthened bendability, improves moulding space, more helps pressing close to skull.
In one embodiment, the both sides of a described screw hole 13 are respectively equipped with a cross-section groove 11.
In another embodiment, meet at right angles with described bottom land along 12 at described groove.
In another embodiment, described screw hole 13 is sunk screw holes 13, and described screw 2 is the biological absorbable and degradable countersunk head nails that insert described screw hole 13, and described countersunk head ailing crown portion is not higher than described groove along 12 height.
Described blade plate can be circular, straight type (consulting Fig. 5), L type (consulting Fig. 6), T type (consulting Fig. 2), X type (consulting Fig. 7) or Y type (consulting Fig. 8) etc.
Each junction point queueing discipline is orderly in above-mentioned circle, straight type, L type, T type, X type or the Y type, such as the X type can form radial arrangement, perhaps curved, directionless selectivity when making its multidimensional moulding, simple to operation.The moulding in any case effect that can reach its bending strength of enhancing.Wherein, the sub-piece of each of blade plate is arranged point and is arranged according to certain distance, point is many when arranging, and is the radial or curved effect that this mainly produces according to the moulding back of product structure from first and last just having formed, and just not be used in the selectivity of considering direction like this in implant into body.
The biological absorbable and degradable blade plate of this utility model can adopt macromolecular material can absorb the synthetism material, can be used in the craniomaxillofacial surgery bone-knitting system.
This utility model chute frame-type biological absorbable and degradable blade plate is a kind of by engineering mechanics principle, clinical medicine, Biological Principles, thereby uses aesthstic knowledge to obtain having the good biological intermiscibility, but degradation in vivo absorbs.Can reach clinically: easy for installation, curative effect is reliable, the advantage that wound is little, and it is reasonable that postoperative reaches degradation time, and effectively supporting time is moderate.Cross-section groove 11 can allow the crooked in any case general frame structure that all can not influence product of product.And also have self-reinforcing, mechanical property height, support to carry effects such as power is big, saving cost.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes this utility model description and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
