Description
Technical field
This utility model belongs to area of medical devices, is specifically related to blade plate technical field of structures.
Background technology
Existing 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, needing to cut larger operative incision when taking out blade plate, adding patient suffering, in order to solve this problem, there is split type 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 memory alloy plate osteosynthesis of intensity.
For realizing the object of this utility model, be achieved by the following technical solutions: a kind of memory alloy plate osteosynthesis, include synthetism mainboard and at least two retainer rings of a strip, described synthetism mainboard outer surface forms the locating slot coordinated with retainer ring in the width direction, locating slot forms two jacks along synthetism mainboard width, and the both sides of locating slot end form positioning port; Described retainer ring includes the rectangular connecting plate of entirety and is integrally connected to two of connecting plate both sides encircles arm, the inner surface of connecting plate is one-body molded has two to coordinate the inserting column of grafting with described jack, connecting plate four vertex positions are one-body molded the chuck coordinated with each positioning port on locating slot, and chuck end coordinates with synthetism mainboard inner surface and clamps; Described synthetism mainboard is that titanium alloy material is one-body molded, and described retainer ring is that memorial alloy is one-body molded.
Preferably: the thickness of described connecting plate and the deep equality of locating slot.
Preferably: the cylindrical or truncated cone-shaped of described inserting column, the end of inserting column is connected with positioning needle.
Preferably: described in encircle arm internal face form evenly distributed raised line.
Preferably: the position on described connecting plate between two inserting columns offers through hole.
Compared with prior art, the beneficial effects of the utility model are: blade plate of the present utility model is by arranging the retainer ring of memory alloy material, together with can fixedly securing with synthetism mainboard easily, Stability Analysis of Structures is reliable, the chuck on retainer ring is then first pried open during dismounting blade plate, then synthetism mainboard is removed, finally remove retainer ring one by one, the great advantage of this blade plate not only utilizes the retainer ring of memorial alloy to the bone that is fixedly clamped, also utilize its self-righting characteristic to make chuck and synthetism mainboard secure fit simultaneously, retainer ring and synthetism mainboard link position is made not to produce relative movement or rock, bonding strength is high.This utility model is applicable to the synthetism of ulna, rib etc.

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 memory alloy plate osteosynthesis, include synthetism mainboard 1 and at least two retainer rings 2 of a strip, described synthetism mainboard outer surface forms the locating slot 11 coordinated with retainer ring in the width direction, locating slot forms two jacks 12 along synthetism mainboard width, and the both sides of locating slot end form positioning port 13; Described retainer ring includes the rectangular connecting plate 21 of entirety and is integrally connected to two of connecting plate both sides encircles arm 22, the inner surface of connecting plate is one-body molded two inserting columns 23 coordinating grafting with described jack, connecting plate four vertex positions are one-body molded the chuck 25 coordinated with each positioning port on locating slot, and chuck end coordinates with synthetism mainboard inner surface and clamps; Described synthetism mainboard is that titanium alloy material is one-body molded, and described retainer ring is that memorial alloy is one-body molded.
The thickness of described connecting plate and the deep equality of locating slot.Such retainer ring is connected the smooth no concave-convex in rear surface with synthetism mainboard.
Cylindrical or the truncated cone-shaped of described inserting column, the end of inserting column is connected with positioning needle 27.Each blade plate generally uses two retainer rings being with positioning needle, and other retainer ring is not with positioning needle.Positioning needle mainly plays location and supplemental support effect, makes the position stability between blade plate entirety and bone, is beneficial to the healing of bone breaking part.
The described internal face encircling arm forms evenly distributed raised line 26.Raised line makes to encircle between arm major part position and bone and leaves gap, is beneficial to the blood fortune of periosteum.
Position on described connecting plate between two inserting columns offers through hole 24.When dismantling retainer ring, instrument can be used to insert in through hole retainer ring is pried open.
During use, first in each drill two holes in bone breaking part both sides, the position in hole is corresponding with the position of two jacks on synthetism mainboard, then retainer ring is cooled, each chuck is broken into two with one's hands, put into synthetism mainboard, one by one retainer ring is loaded, carrying out heating with warm saline to retainer ring after retainer ring is all in place makes chuck recover original-shape, chuck end is clamped in synthetism mainboard inner surface, encircling arm is clamped on bone, can make retainer ring and synthetism mainboard secure fit like this, thus be fixed bone.
Then first cool retainer ring during dismounting blade plate, remove retainer ring one by one, then remove mainboard.
