Abstract
A kind of percutaneous vertbroplasty bone cement injects more piece segment sync micro controller, is designed to the flow dividing structure of One In and Two Out.Two rates of discharge can be adjusted by an adjusting screw, be equipped with scale by adjusting screw, have scale on scale, can show the accurate location of adjusting screw, can further calculate the openings of sizes of two outlets and the flow of two outlet bone cements.If there are three inject a little, can a present apparatus be connect again in one outlet wherein, if there are four inject that a little a present apparatus can be connect respectively again in two outlets, if there are five the above mouths of injecting can use same method successively drop-over, and can control each flow exported by adjusting the adjusting screw on each device.The present apparatus may be implemented multiple spot while inject, and bone cement, which once mixes up, once injects, and setting time is easy to control.Multiple spot only uses an injector, at low cost.X-ray irradiation is primary, and it is small that patient receives amount of radiation.
Description
Technical field:
The utility model relates to a kind of percutaneous vertbroplasty bone cements to inject more piece segment sync micro controller
Background technique:
With the arrival of aging society, the incidence of osteoporosis is risen year by year, incident osteoporotic
The incidence of fracture (OPF) also increases accordingly.The common happening part of OPF is backbone, hip, distal forearm.Especially backbone
The osteoporotic fracture at position can often occur in patient's tiny movement accidentally or damage, lead to severe pain,
Moving obstacle brings huge economy and living burden to society and patient home.In recent years, it is perfused using percutaneous bone cement
Vertebroplasty treats such damage, achieves certain effect, has and relieves pain fast, the good advantage of effect.But with
The case number of clinical treatment expands, it has been found that such technology has certain defect.The complete application of such instrument, a set of instrument
It can be only applied to a centrum, it is expensive.It is huge for the patient economy burden that multiple segment vertebral fractures occur simultaneously；And
And multiple segments cannot be carried out simultaneously in surgical procedure or the bone cement of multiple points of puncture is injected, cause multiple x-ray saturating
Depending on it is excessive that patient receives x-ray radiation amount；Due to being limited by bone cement setting time, operation time must be as far as possible
It is completed in the short time, for example multi-segmental or multiple spot treatment, bone cement disperse in centrum may occur since bone cement hardens
It is bad, it can not inject, can not be inserted into puncture needle core causes to extract puncture needle and form the complication such as hangover.
Summary of the invention:
The utility model provide in view of the above drawbacks of the prior art a kind of percutaneous vertbroplasty bone cement inject it is more
Segment synchronizes micro controller, and the utility model is designed to that the flow dividing structure of One In and Two Out, the flow of two outlets can pass through one
Adjusting screw is adjusted, and is equipped with scale by adjusting screw, has scale on scale, can show the accurate location of adjusting screw, into
One step shows the opening and closing amount of two outlets, convenient for users to calculating the flow of two outlet bone cements.If there are three injecting a little,
A present apparatus can be connect again in one outlet wherein, if there are four inject a little export at two connect one respectively again
A present apparatus, if there are five the above mouths of injecting can use same method successively drop-over, and by each device
Adjusting screw corrdinated adjustment come adjust each outlet flow.The present apparatus may be implemented multiple spot while inject, and bone cement is primary
It mixes up and once injects, setting time preferably controls.Multiple spot only uses an injector, and at low cost, patient's financial burden is light.X-ray
Once irradiating, it is small that patient receives amount of radiation.
Its technical problem is solved to adopt the technical scheme that:
The utility model is by nut, left delivery channel, Screw, scale, adjusting screw, piston, right end cap, rubber pad
Piece, plunger, compressed spring, head bolts, left end cap, right delivery channel, into conduit, the composition such as shell.
