Description
Technical field
The utility model relates to medical research fields, specifically, being accuracy manufacture rat femur bone nonunion model
Mechanical operation platform.
Background technique
Fracture is common disease clinically, often brings considerable distress to sufferer.Fracture have after occurring 9% ratio because
The bad generation for causing bone nonunion after many reasons cause more causes further deformity, causes serious social influence.Therefore needle
Research to research fracture and bone nonunion has important social effect.
For fracture with the research of bone nonunion, most important premise is exactly the foundation of standard fracture model.By different
Same area manufacture same position, broken ends of fractured bone active level, the identical height of soft tissue injury degree of the animal of experimental group can weigh
The fracture defect of renaturation keeps the position of fracture, intensity relatively controllable, to reach the characteristics of studying fracture and bone nonunion.Current
Zooscopy in, rat is most common experimental animal, is widely used in the research of various fracture.However, the individual of animal
The problem that the accuracy of difference, modeling method difference and modeling is uncontrollable constrains the research of fracture and bone nonunion.
Therefore a kind of stabilization, reusable fracture preparation facilities are needed to guarantee the controllability of experiment.It is currently manufactured
The device of fracture can be divided into interior fixation and outer fixed according to the type of fracture fixation.The main basis of the device of interior fixed
The model that Einhorn in 1984 is proposed is established, and although which can be reduced soft tissue injury, but device is complex.It is outer solid
It is formed and fixes targeted bone in vitro in experimental animal, but need to be installed at experimental animal, it is at high cost and influence animal
Normal activity operates also relatively complicated.
Chinese patent literature CN:CN201710652410.8 discloses a kind of zoopery fracture model preparation facilities,
Structure includes that pedestal, support plate, two support lateral columns, force application mechanism and two support chips, the support-side column symmetry are fixed on
On pedestal, the support plate is horizontally arranged between two side columns, and the force application mechanism is by be vertically fixed in support plate two
Spring loop bar, the identical spring of two specifications being respectively fitted on two spring loop bars, weight bearing plate and force application rod are constituted,
The force application rod passes perpendicularly through weight bearing plate and fixation, and the weight accepts sleeve-board on two spring loop bars, by spring supporting,
Rod axis and two spring pocket rod axis exert a force on same vertical plane, and equidistant with two spring loop bars, force application rod lower end is movably
The perforation being correspondingly arranged in support plate is passed perpendicularly through, described two support chips can be relatively movably mounted on the base.This is practical
The manufacture of the relatively uniform fracture site in novel realization position, and soft-tissue trauma is reduced to a certain extent.But about one
Kind can manufacture a variety of different fracture, and stablize reusable fracture model manufacture instrument and yet there are no disclosure.
In conclusion needing a kind of fracture preparation facilities easy to use, effect stability, a variety of different fracture can be manufactured
Model, and accuracy is high, repeatability is high, the standardized instrument of the fracture situation of different experiments body, and this instrument yet there are no report
Road.
