Background technology
Existing combined memory alloy plate osteosynthesis is mostly integral type structure, multiple arm of encircling integrally is connected on a mainboard, first blade plate cooling is made it bent distortion during use, progressively restPose under body temperature effect after blade plate is in place, easy to use, substantially reduce the time of fracture reduction operation.But this kind of blade plate overall volume is relatively large, need to cut larger operative incision when taking out blade plate, add patient suffering, in order to solve this problem, there is split type combined memory alloy plate osteosynthesis, namely encircle arm to be separated with mainboard, be fixedly connected with mainboard after encircling arm recovery of shape, can take out separately when taking out blade plate like this and eachly encircle arm, operative incision is relatively much little, but the bonding strength encircling arm and mainboard is not high, and easily produce displacement, result of use is undesirable.
Summary of the invention
Technical problem to be solved in the utility model is: the deficiency existed for prior art, provides a kind of rational in infrastructure, the reliable combined memory alloy plate osteosynthesis of intensity.
For realizing the object of this utility model, be achieved by the following technical solutions: a kind of combined memory alloy plate osteosynthesis, include the synthetism mainboard of a strip and at least two encircle arm, described synthetism mainboard outer surface forms in the width direction and the locating slot encircled arm and coordinate, the long side face of synthetism mainboard is positioned at the breach of the position formation indent of locating slot, the both sides of position, locating slot both ends form the location plush copper protruding upward near locating slot edge, and position synthetism mainboard being positioned at breach forms the external splint extended in opposite directions; Medium position synthetism mainboard being positioned at locating slot forms inner splint, the gap of a U-shaped is formed between inner splint and synthetism mainboard, the two ends in U-shaped gap extend to outside locating slot along synthetism main board length direction, inner splint lower surface forms fixing plush copper, and fixing plush copper is positioned at the center of locating slot; Described arm of encircling is circular arc, the width encircling arm is identical with locating slot width, encircle arm intermediary form and have the first locating hole coordinating grafting with fixing plush copper, encircle the second locating hole arm also forming and to locate plush copper with each on a locating slot and coordinate grafting respectively; Described synthetism mainboard and to encircle arm one-body molded by memorial alloy.
Preferably: described in encircle arm thickness be the 2/3-3/4 of the degree of depth of locating slot; Described external splint upper surface is concordant with synthetism mainboard, and the thickness of external splint is the 1/2-2/3 of clamping slot depth.Can not reset into initial position when external splint restores like this, the outer end of external splint produces a prestressing force to encircling arm all the time, makes to encircle arm and is closely adjacent to and is not shifted in locating slot.
Preferably: described in encircle arm internal face form evenly distributed raised line.That encircles that arm differs from raised line like this leaves gap between other position and bone, is beneficial to periosteum blood fortune, contributes to the healing of bone breaking part.
Compared with prior art, the beneficial effects of the utility model are: synthetism mainboard of the present utility model carries out spacing, fixing by molding locating slot, location plush copper, external splint, inner splint, fixing plush copper multi-angle to encircling arm, make to encircle configuration state after arm is connected to synthetism mainboard to stablize, bonding strength with encircle no significant difference compared with intensity that arm is molded directly within synthetism mainboard.

Detailed description of the invention
With reference to the accompanying drawings detailed description of the invention of the present utility model is made a detailed explanation below.
Embodiment 1.
According to shown in Fig. 1 to Fig. 4, the present embodiment is a kind of combined memory alloy plate osteosynthesis, include the synthetism mainboard 1 of a strip and at least two encircle arm 2, described synthetism mainboard outer surface forms in the width direction and the locating slot 14 encircled arm and coordinate, the long side face of synthetism mainboard is positioned at the breach of the position formation indent of locating slot, the both sides of position, locating slot both ends form the location plush copper 13 protruding upward near locating slot edge, and position synthetism mainboard being positioned at breach forms the external splint 12 extended in opposite directions; Medium position synthetism mainboard being positioned at locating slot forms inner splint 15, the gap of a U-shaped is formed between inner splint and synthetism mainboard, the two ends in U-shaped gap extend to outside locating slot along synthetism main board length direction, inner splint lower surface forms fixing plush copper 16, and fixing plush copper is positioned at the center of locating slot; Described arm of encircling is circular arc, the width encircling arm is identical with locating slot width, encircle arm intermediary form and have the first locating hole 22 coordinating grafting with fixing plush copper, encircle the second locating hole 23 arm also forming and to locate plush copper with each on a locating slot and coordinate grafting respectively; Described synthetism mainboard and to encircle arm one-body molded by memorial alloy.
Described location plush copper coordinates with external splint, add coordinating of location plush copper and the second locating hole, make to encircle between each vertex position of arm and locating slot and do not produce relative twisting, inner splint and fixing plush copper coordinate the first locating hole to make to encircle arm can not produce distortion in the circumferential, enables to encircle arm and produces stable pressure to bone for a long time.Described U-shaped gap extends to outside locating slot, inner splint can be dug by a relatively large margin, be convenient to the loading of encircling arm.
Synthetism mainboard also forms screw hole 11, to be connected with bone by screw that to guarantee that bone obtains in the longitudinal direction good fixing, coordinate the protection of encircling arm, stable support can be reached, be especially applicable to the situation of bone breaking part both sides with longitudinal bone splits.
The described thickness encircling arm is the 2/3-3/4 of the degree of depth of locating slot; Described external splint upper surface is concordant with synthetism mainboard, and the thickness of external splint is the 1/2-2/3 of clamping slot depth.Can not reset into initial position when external splint restores like this, the outer end of external splint produces a prestressing force to encircling arm all the time, makes to encircle arm and is closely adjacent to and is not shifted in locating slot.
The described internal face encircling arm forms evenly distributed raised line 21.That encircles that arm differs from raised line like this leaves gap between other position and bone, is beneficial to periosteum blood fortune, contributes to the healing of bone breaking part.
During use, first at least individual brill hole, bone breaking part both sides, the position in hole is corresponding with the position of two screw holes on synthetism mainboard, then arm will be encircled and synthetism mainboard cools, by each external splint, inner splint is broken into two with one's hands, put into synthetism mainboard, screw is first used to be fixed on bone by synthetism mainboard, arm will be encircled subsequently one by one break into two with one's hands and load, guarantee that the second locating hole snaps in the location plush copper of correspondence position, encircle arm be all in place after with warm saline to encircling arm, synthetism mainboard carries out heating makes external splint, inner splint recovers original-shape, encircle arm namely with synthetism mainboard secure fit, thus bone is fixed.
Then first cool synthetism mainboard during dismounting blade plate and encircle arm, removing one by one and encircle arm, then remove synthetism mainboard.
