Description
Technical field
The invention belongs to the medicine equipment used during Bone Defect Repari, especially for one kind of injected bone repairing material injection
Apparatus, and in particular to for a kind of injecting apparatus of the injection-type gel bone renovating material of quantitative constant speed.
Background technology
Make some sclerotin of bone loss due to osteoporosis, wound, tumour, infection and other diseases, formed larger
The phenomenon in gap is referred to as Cranial defect.Most Cranial defects are all difficult self-heal, malpractice or not in time last easy shape
Into bone nonunion, the life to patient brings many difficulties.At present, the repair mode of Cranial defect predominantly using autologous bone transplanting or
The mode of homogeneous allogenic bone transplantation, autologous bone carry tool osteogenic action because having bone-inducting active and bone conduction effect concurrently
Bone marrow cell, therefore still regard as " goldstandard " at present, but autologous bone limited source, and take the extra pain of injury of bone increase patient；Allosome
Different degrees of immunological rejection be present and propagated with potential pathogeny dangerous in bone；In recent years, clinically can also use each
The artificial bone of the manufactures such as kind metal, high polymer material or ceramics substitutes to defect, still, after the implantation of these materials
Potential increase bone loss amount all be present, cause the risk of the damage of surrounding tissue, patient is born larger operation wound etc.
Shortcoming, therefore clinical practice is less.
At present, as the continuous progress of Minimally Invasive Surgery technology and the development of Injectable bone repair material technology, utilization are minimally invasive
Operation overcomes the deficiency of complete artificial bone substitute materials with reference to Injectable bone repair material repairing bone defect, and is greatly enhanced
The security and practicality of operation, and surgery cost is low, damage is small.The bone renovating material of the injectable clinically used at present
Mostly temperature sensitive hydrogel material, such as 201310627494.1, a kind of hollow hydroxyapatite micro-sphere/chitosan of injectable is compound
Drug carrier material and preparation method thereof, its disclosed combination drug carrier material can coagulate after entering back into human body under body temperature
Gel, the support with three-dimensional porous structure is formed, and play the effect of osteoacusis.
But influenceed by Cranial defect position situation, it is necessary to injection volume and its injection speed be controlled, to ensure to be formed effectively
The three-dimensional rack being coincide with Cranial defect position shape.The injection system of current injection is injected narrow by the combination of normal injection apparatus
Pipe is injected, and the control of injection speed and injection volume is completely dependent on the clinical experience of doctor, and doctor goes back in operation
The direction for having control to inject, ensures the accuracy of injection phase, existing injecting apparatus to requiring high to doctor and workload is big,
Slip up higher, and then the recovery situation of patient can be influenceed.Therefore one kind is needed effectively to control injection volume and injection speed
Injecting apparatus solve above-mentioned technical problem.
Present inventive concept for injection volume existing for existing bone renovating material injecting apparatus and injection speed can not control,
And then the problem of influenceing surgical effect, there is provided it is a kind of rational in infrastructure, use the simple injection-type gel Bone Defect Repari for quantifying constant speed
The injecting apparatus of material.
