Abstract
The utility model discloses a novel anticorrosion coaptation board, this coaptation board is the bar sheet metal, has 2 screw holes on its face at least for fixing of coaptation board, its characterized in that: the densely covered blind hole in coaptation board surface, the inside packing of blind hole can promote the various medicines of skeleton healing and metal or the alloy that active nature is higher than coaptation panel matter. The internal fixed or plastic restoration use of mainly used people or animal fracture. The coaptation board of contrast clinical practice, the utility model discloses the coaptation board announced gathers the blind hole through the surface and has reduced the modulus of coaptation board, effectively reduces the stress occlusion effect, and the medicine of packing in the blind hole helps promoting the healing of fracture, and high active nature metal utilizes sacrificial anode's cathodic protection principle protection coaptation panel material not corroded.
Description
Technical field
This utility model belongs to the fixed apparatus field of orthopaedics in medical apparatus and instruments, particularly a kind of Novel anticorrosion blade plate.
Background technology
The blade plate used clinically at present is mostly made up of rustless steel, cobalt-base alloys and titanium alloy, although these material corrosion resistances are better, mechanical property is not mated with tissue mechanical property, easily produces stress shielding effect, affect symphysis, even cause and again damage.
Magnesium alloy has the characteristics such as more excellent mechanical property and degradable as new medical metal material, stress capture-effect can be avoided and taken out the secondary injury caused by implant, but magnesium alloy corrodes comparatively fast in human body environment, has a negative impact to the recovery of osseous tissue.
Summary of the invention
The purpose of this utility model is to provide a kind of Novel anticorrosion blade plate, uses for human or animal's fractured type internal fixtion or Plastic renovation.
This utility model specifically provides a kind of Novel anticorrosion blade plate, and blade plate is thin strip-plate, and there is multiple screw hole in its plate face, and fixing for blade plate, blade plate is concave surface or cambered surface towards the one side of skeleton, to improve the combination degree of blade plate and skeleton.The densely covered blind hole in blade plate surface, the medicine and high activity metal or alloy that promote bone healing are filled in blind hole inside.
Blade plate material is medical magnesium calcium alloy, also can be other model magnesium alloy or titanium alloy, cobalt-base alloys.Screw hole on blade plate and blind hole are circular hole, and screw hole adopts drilling processing, and blind hole adopts spark machined, and diameter is between 2mm-4mm, and blind hole can be uniformly distributed on blade plate surface, also can be random distribution.
The method of blind hole of being gathered by surface, reduce further the elastic modelling quantity of blade plate, makes blade plate and osseous tissue mechanical property difference be down to minimum.Blade plate fills the medicine promoting bone healing in the blind hole of skeleton, medicine take metal as carrier, outside carrier for antiinflammatory, ease pain, class of invigorating blood circulation medicine, promoting skeleton quickly-healing, is health-related medicine inside carrier, when such arrangement makes blade plate firm implant into body, outside carrier, medicine can act on osseous tissue immediately, promotes osseous tissue healing, along with the corrosion of carrier metal, health-related medicine inside carrier is released, and acts on newly-generated osseous tissue.
Other surperficial blind hole fills the pure magnesium of casting; the metal activity of pure magnesium is higher than magnesium calcium alloy; when there is corrosiveness in human body environment; pure magnesium is first corroded; reach the cathodic protection effect of sacrificial anode; filler metal be corroded complete before, blade plate material magnesium calcium alloy can not be corroded, and extends the life-span of blade plate in this way.

Detailed description of the invention
Magnesium calcium alloy is processed into required form through the processing method such as punching press, polishing, and through drilling, spark machined screw hole and blind hole, workpiece is filled drug and the higher metal of metal activity after surface clean.
Example 1:
What Fig. 1, Fig. 2 illustrated is straight type blade plate.In Fig. 1, what the blind hole of the convex surface of blade plate and side was filled is the pure magnesium of casting, and in Fig. 2, what the blind hole of blade plate concave surface was filled is the medicine promoting that bone healing is repaired.
Example 2:
What Fig. 3, Fig. 4 illustrated is T-shaped blade plate.In Fig. 3, what the blind hole of the convex surface of blade plate and side was filled is the pure magnesium of casting, and in Fig. 4, what the blind hole of blade plate concave surface was filled is the medicine promoting that bone healing is repaired.
Fig. 5 fills the pure magnesium of casting used, and pure magnesium is cylindric, but needs according to filling position processing end face.
Fig. 6 is for filling medicine used, and pharmaceutical carrier is the pure magnesium of casting, and this pure magnesium is cellular, drug particles be filled in cellular pure and beautiful in, near skeleton side fill antiinflammatory, analgesia, blood circulation promoting medicine, opposite side fills health-related medicine, with the corrosion degradation of carrier metal, sustained release.
Blade plate can make various shape according to actual service condition.
The object of above-mentioned example is that thought of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to this utility model spirit change or modify, and all should be encompassed within protection domain of the present utility model.
