Abstract
The utility model discloses a rabbit long bone defect repair model fixing device. The rabbit long bone defect repair model fixing device comprises two arc-shaped plates which are buckled into a tubular structure. The front ends and the back ends of the two arc-shaped plates are correspondingly provided with positioning holes respectively, and fixing steel wires penetrate through the positioning holes. The front end and the back end of each arc-shaped plate are respectively provided with two positioning holes, the number of the fixing steel wires is two, the two ends of each fixing steel wire penetrate through the two positioning holes in one arc-shaped plate respectively and then penetrate out of the two positioning holes in the other arc-shaped plate to be tied and connected. The pipe diameter of the tubular structure formed by buckling the two arc-shaped plates is matched with the diameter of the rabbit long bone. The rabbit long bone defect repair model fixing device has the advantages of being simple and compact in structure, convenient to manufacture, firm in fixing, and capable of meeting the experiment requirements of bone defect repair models with different defect lengths in the middle section of the rabbit long bone.
Description
Technical field
This utility model relates to the fixture that experimental zoology field is used, and especially relates to a kind of rabbit ' Bone Defect of Long Bones repairing model fixture.
Background technology
The reparation that bone is damaged is a great problem of clinical orthopaedics with rebuilding, and it is one of conventional method for reconstructing that bone is transplanted.Many scholars are devoted to the research of the bone grafting materials such as deep-frozen homogeneous allogenic bone, tissue engineered artificial bone in recent years, and the selection of trying hard to start with as clinical bone grafting material from experimentation provides theoretical foundation.The research of bone grafting material need to be prepared suitable animal model, and experiment is that bone is transplanted one of conventional laboratory animal with rabbit, and it is with low cost, and can observe well the mechanism of action of bone grafting material in osteogenetic process.But, after bone transplant operation particularly in bone defect repair process, because rabbit is movable, if the fixing not firm meeting of long bone causes graft materials to deviate to cause the failure of an experiment, so the fixing quality of long bone directly affects the observation of follow-up repair process in rabbit ' Bone Defect of Long Bones repair process.At present, test technique for fixing in conventional Kirschner wire marrow and require high and easy infection, if unfixing, tend to cause graft materials skew, dislocation, free.Due to Os Leporis seu Oryctolagi fine microstructures, still lack at present good fixed apparatus and method.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, rabbit ' Bone Defect of Long Bones repairing model fixture that can meet requirement of experiment.
For achieving the above object, this utility model can be taked following technical proposals:
Rabbit ' Bone Defect of Long Bones repairing model fixture described in the utility model, it comprises after two fastenings arc in tubular construction, in the front-end and back-end of described two arcs, correspondence offers locating hole respectively, is equipped with fixedly steel wire in described locating hole.
The locating hole of described every arc front-end and back-end is respectively two, and described fixedly steel wire is two, every fixedly steel wire two ends respectively two locating holes from an arc penetrate from two locating holes of another piece arc pass knotting and connect.
Caliber after described two arcs fasten and the bone footpath of rabbit long bone adapt.
The utility model has the advantage of simple and compact for structurely, easy to make, fixation, can meet the requirement of experiment of the bone defect repair model of the different defect length in rabbit long bone stage casing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 be Fig. 1 M-M to sectional structure schematic diagram.
The specific embodiment
As shown in Figure 1, 2, rabbit ' Bone Defect of Long Bones repairing model fixture described in the utility model, comprise arc 1 in tubular construction after two fastenings, caliber after two arcs 1 fasten and the bone footpath of rabbit long bone 4 adapt, in the front-end and back-end of two arcs 1, correspondence offers locating hole 2 respectively, is equipped with fixedly steel wire 3 in locating hole 2; For guaranteeing fixation, the locating hole 2 of every arc 1 front-end and back-end is respectively two, fixedly steel wire 3 is two, every fixedly steel wire two ends respectively two locating holes from an arc penetrate from two locating holes of another piece arc pass knotting and connect.
During use, first graft 5 is filled in to the damaged place of bone at rabbit long bone 4 middle parts, can be with steel plate during by two arc 1(Practical manufacturings) be fastened on the opposite face of rabbit long bone 4, with electric drill, from the osseous tissue of two arc 1 front-end and back-end locating hole 2 corresponding positions, hole, then by a rear knotting connection of four locating holes 2 that fixedly two arc 1 front ends are passed respectively at the two ends of steel wire 3, another root is fixedly connected through the rear knotting of four locating holes 2 of two arc 1 rear ends respectively at the two ends of steel wire 3, two arcs 1 are firmly fixed on rabbit long bone 4, prevent its graft 5 sliding transfers, met the experimentation of observing graft Osteogenic Mechanism after transplanting.
