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.When so will remove blade plate after bone heals, be not easy to cool away from the part of mainboard owing to encircling arm, such needs cuts larger operative incision, add 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 of environmental protection arm and mainboard is not high, easy generation 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, and provide a kind of rational in infrastructure, intensity is reliable, and installing/dismounting is spliced blade plate all conveniently.
For realizing the object of this utility model, be achieved by the following technical solutions: a kind of spliced blade plate, include mainboard and at least two fixing bands of a strip, described mainboard outer surface forms the locating slot coordinated with fixing band in the width direction, locating slot has two jacks along mainboard width symmetrical molding; Described fixing band two ends respectively form a connecting hole; Described mainboard is connected with the fixture of locating fixing band, the internal face of fixture forms fixed leg, fixed leg is through described connecting hole and jack; The both sides of described locating slot end form positioning port, and on fixing band, the position of corresponding positioning port forms locating notch, and the position of the corresponding positioning port in two ends of described fixture is one-body molded chuck, and chuck reaches mainboard inner surface from positioning port; Described mainboard and fixing band are that titanium alloy material is one-body molded, and described fixture is memorial alloy.
Preferably: the thickness of described fixing band and the deep equality of locating slot.
Preferably: the cylindrical or truncated cone-shaped of described fixed leg, the end of fixed leg is connected with positioning needle.Positioning needle coordinates fixing with the hole of boring out on bone in advance, can not produce displacement after blade plate is installed.
Preferably: described fixing band is spliced to form by two sections.
Compared with prior art, the beneficial effects of the utility model are: blade plate of the present utility model is by arranging the fixture of memory alloy material, can fixing band and mainboard be fixed together easily, Stability Analysis of Structures is reliable, then first removes fixture during dismounting blade plate, then mainboard is removed, finally remove fixing band one by one, fixing band is thinner titanium alloy, compares memorial alloy and easily removes, reducing operative incision when removing blade plate like this, operating also more convenient.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. 5, the present embodiment is a kind of spliced blade plate, include mainboard 2 and at least two fixing bands 3 of a strip, described mainboard outer surface forms in the width direction the locating slot 21 coordinated with fixing band, locating slot has two jacks 23 along mainboard width symmetrical molding; Described fixing band two ends respectively form a connecting hole 31; Described mainboard is connected with the fixture 1 of locating fixing band, the internal face of fixture forms fixed leg 11, fixed leg is through described connecting hole and jack; The both sides of described locating slot end form positioning port 22, and on fixing band, the position of corresponding positioning port forms locating notch 32, and the position of the corresponding positioning port in two ends of described fixture is one-body molded chuck 12, and chuck reaches mainboard inner surface from positioning port; Described mainboard and fixing band are that titanium alloy material is one-body molded, and described fixture is memorial alloy.
The thickness of described fixing band and the deep equality of locating slot.Like this after fixture is installed on mainboard, fixing band and mainboard are completely fixed, and can not produce and rock.
Cylindrical or the truncated cone-shaped of described fixed leg, the end of fixed leg is connected with positioning needle 14.Fixture divides two kinds, and a kind of band positioning needle one is not with positioning needle, and each blade plate generally uses two fixtures being with positioning needles in the both sides of fracture, and the fixture of other position then uses not with positioning needle.Positioning needle coordinates fixing with the hole of boring out on bone in advance, can not produce displacement after blade plate is installed.Position on fixture between two fixed legs offers through hole 13, uses instrument to insert in through hole and pried open by fixture during fixture for convenience detach.
Described fixing band is spliced to form by two sections.Like this dismantle fixing band time two sections take out at twice, more convenient operation.
During use, first fixing band is installed to the both sides of fracture, 2-3 fixing band is installed in every side as required, and the spacing adjusting two adjacent locating slots on distance between adjacent two fixing bands and mainboard is roughly equal; Then fixture cooling is made it bent, the chuck of fixture is broken into two with one's hands; Each fixture is put into respectively the locating slot of mainboard, fixed leg is made to pass described connecting hole 31 and jack 23, fixing band two ends and mainboard are completely fixed, carrying out heating with warm saline to fixture after each fixing band is all in place makes chuck 12 recover original-shape, chuck end is clamped in mainboard inner surface, fixing band and mainboard secure fit can be made like this, thus bone is fixed.
Then first fixture is cooled during dismounting blade plate, remove fixture, then mainboard is removed, finally remove fixing band one by one, fixing band is thinner titanium alloy, and is two sections of being spliced to form, and compares memorial alloy and easily removes, reducing operative incision when removing blade plate like this, operating also more convenient.
