Abstract
The utility model discloses a kind of split type blade plate, include the synthetism mainboard of a strip and at least two encircle arm, described synthetism mainboard outer surface forms and the locating slot encircled arm and coordinate, the both sides of position, locating slot both ends form the location plush copper protruding upward near locating slot edge, and locating slot center forms jack; Described synthetism mainboard is connected with a fixed frame by described chuck; Described synthetism mainboard is that rigid titanium alloy material is one-body molded, described fixed frame and to encircle arm one-body molded by memorial alloy respectively.To be coordinated with chuck by fixed frame and will encircle arm and be completely fixed on synthetism mainboard, 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, and the requirement of easy disassembly can be met again, shorten operating time, alleviate patient suffering.
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 split type blade plate 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 split type blade plate, 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 split type blade plate of intensity.
For realizing the object of this utility model, be achieved by the following technical solutions: a kind of split type blade plate, 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 locating slot center forms jack; The both sides described synthetism mainboard being positioned at each locating slot end form upwards bending and the relative chuck in end.
Described arm of encircling is made up of a titanium alloy arm plate and a memorial alloy arm plate, titanium alloy arm plate one end is connected with the contact pin coordinated with jack, the other end is the narrow trapezoidal connecting portion in wide the inner, outer end, and the position near contact pin and away from titanium alloy arm plate end on titanium alloy arm plate forms one group of locating hole; Described memorial alloy arm plate one end offers the elliptical aperture coordinated with contact pin, the both sides of the other end form the second chuck coordinating with trapezoidal connecting portion and clamp, and the position near elliptical aperture and away from memorial alloy arm plate end on memorial alloy arm plate forms at least two group locating holes; The inner surface of described memorial alloy arm plate and titanium alloy arm plate all forms raised line.
Described synthetism mainboard is connected with the fixed frame of a rectangular box shape by described chuck, encircle arm and be clamped between described synthetism mainboard and fixed frame; Described synthetism mainboard is that rigid titanium alloy material is one-body molded, described fixed frame and to encircle arm one-body molded by memorial alloy respectively.
Compared with prior art, the beneficial effects of the utility model are: synthetism mainboard of the present utility model carries out spacing by molding locating slot, location plush copper to encircling arm, to be coordinated with chuck by fixed frame simultaneously and will encircle arm and be completely fixed on synthetism mainboard, 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, and the requirement of easy disassembly can be met again, shorten operating time, alleviate patient suffering; Described trapezoidal connecting portion coordinates with the second chuck, makes to encircle after arm is in place to produce prestressing force to bone, improves the bonding strength of blade plate.

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. 3, the present embodiment is a kind of split type blade plate, include the synthetism mainboard 2 of a strip and at least two encircle arm 3, described synthetism mainboard outer surface forms in the width direction and the locating slot 21 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 22 protruding upward near locating slot edge, and locating slot center forms jack 24; The both sides described synthetism mainboard being positioned at each locating slot end form upwards bending and the relative chuck 23 in end.
Described arm of encircling is made up of a titanium alloy arm plate 31 and a memorial alloy arm plate 32, titanium alloy arm plate one end is connected with the contact pin 301 coordinated with jack, the other end is the narrow trapezoidal connecting portion 311 in wide the inner, outer end, and the position near contact pin and away from titanium alloy arm plate end on titanium alloy arm plate forms one group of locating hole 303; Described memorial alloy arm plate one end offers the elliptical aperture 302 coordinated with contact pin, the both sides of the other end form the second chuck 321 coordinating with trapezoidal connecting portion and clamp, and the position near elliptical aperture and away from memorial alloy arm plate end on memorial alloy arm plate forms at least two group locating holes; The inner surface of described memorial alloy arm plate and titanium alloy arm plate all forms raised line 304.
Described synthetism mainboard is connected with the fixed frame 1 of a rectangular box shape by described chuck, encircles arm and is clamped between described synthetism mainboard and fixed frame; Described synthetism mainboard is that rigid titanium alloy material is one-body molded, described fixed frame and to encircle arm one-body molded by memorial alloy respectively.
