Abstract
A kind of manufacture method that is used for repair of cranial defects with NiTi alloy rivet and NiTi plate, after principal character is to heat respectively, air cooling and hot rolling, NiTi alloy rivet and NiTi plate with the inventive method manufacturing, behind the implant into body, rivet presents good memory effect under surgical condition, the then memoryless reaction of NiTi plate, keep shape invariance, thereby preferably resolve the problem that exists in the repair of cranial defects process.The inventive method is simple, is easy to realize that the NiTi alloy rivet of manufacturing is identical with panel material, can not produce galvanic corrosion, and the memory effect difference, thus realize different functions of use, be a kind of comparatively ideal cerebral surgery operation material.
Description
The present invention relates to a kind of treatment process, belong to the metal treatment method repair of cranial defects usefulness Ni-Ti alloy rivet and plate in the medical surgery operation.
In the prior art, repair of cranial defects generally adopts synthetic glass or titanium plate, and with silk thread, Stainless Steel Wire or screw retention, synthetic glass is thicker, frangible, biocompatibility is poor, foreign body reaction and aging easily takes place.The titanium plate is firmer, good biocompatibility, but because plasticity is poor, can't in operation, will repaiies multiplex plate according to the skull defeci situation and be moulded the shape that matches with the skull surface shape, damage scalp so imprecision or edge perk take place to cover easily, need operation once more when serious.Another problem in the skull defect repair surgery is fixing plate, with silk thread as immobilization material, the silk thread fracture takes place easily and cause the displacement of reparation plate, need the skull holostrome is bored saturating with Fixation With Steel Wire, operation need be deep into encephalic, and the danger of injured brain tissue is arranged, and postoperative easily produces intracranial hematoma, and scalp can stay bigger steel wire knot down, be screwed, because lamina externa cranii is thinner, each thickness difference, screw is difficult to adapt to fully, and easily get loose, above-mentioned three kinds of fixing meanss operation is all complicated, and operating time is long, prognosis is undesirable, and the situation of repeat surgery happens occasionally.
Because the memorial alloy rivet is very convenient in surgical operation is used, gradually adopted at present, but wish that in skull defect repair surgery employed plate is behind typing, fixing implantation scalp, its external form remains unchanged, the employed fixing good memory effect that presents with rivet, under surgical condition.Because the metallic substance of different components can produce galvanic corrosion after inserting human body.Therefore, the plate that repair of cranial defects is used must be identical composition with rivet, and the material of different memory effects is but arranged.Up to the present, fail a suitable method always, make the NiTi alloy memory rivet and the NiTi plate of composition of the same race, the former has good memory effect under surgical condition, the latter then has the easy machining deformation of good plasticity, knock and can be deformed into the dome shape that adapts with the skull surface shape according to the operation needs with hand hammer, enough strength and stiffness are arranged, the back implant into body that is shaped does not present memory effect.
The objective of the invention is to propose a kind of method, the NiTi memorial alloy is carried out different processing, make NiTi memorial alloy rivet after treatment, under surgical condition, present good memory effect behind the implant into body and produce distortion, and NiTi plate does not after treatment present memory effect and does not deform in that similarity condition is next.
The following processing of process using of the present invention has reached above-mentioned purpose, select Ms to be about 25 ℃ Ti-54%Ni alloy as the manufactured materials of rivet and NiTi plate, rivet adopts 800-880 ℃ of heating air cooling under riveting status, at room temperature be the parent phase of the forwarding of small amount of thermal martensitic stucture+not, can obtain complete martensitic stucture when being chilled to 5 ℃-10 ℃, yielding, the rivet pawl can be easy to be dialled straight, is heated to 33-37 ℃, and change can take place to reverse fully, shape 100% is recovered, and promptly recovers riveting status.
Hot rolling after 800-880 ℃ of heating of composition NiTi plate employing of the same race, below the Md point, obtain strain induced martensite, has advantages of higher stability, the Ms point is increased to more than 60 ℃, be placed on the change that can not take a turn for the worse under the surgical condition, thereby do not present shape memory effect, this strain induced martensite has very high deformability, so the NiTi plate is easy to knock distortion with hand hammer when operation, to adapt to skull shape needs, can reach complete driving fit, the NiTi plate is after cold plastic deformation, the stability of its strain induced martensite further improves, and the intensity rising, so be difficult for redeformation after being shaped.
NiTi memorial alloy rivet and NiTi plate with art breading of the present invention are reparation of ideal skull and immobilization material, and it possesses following characteristics:
1. the rivet fixing operation is easy, because of the composition of rivet and NiTi plate identical, so electrolytic corrosion can not take place;
2.NiTi plate has good plasticity under surgical condition, be easy to distortion, can the nitinol sheet shape be reached and the complete driving fit of skull opening cranium backsight patient practical situation; Easy to operation.
3. the distortion recovery temperature of MiTi plate can not deform after the placement human body is interior more than 60 ℃ under surgical condition.
