Description
Technical field
The present invention relates to the field of medical instrument technology, specifically, being a kind of endoscopic ultrasonography puncture of quantitatively control negative pressure
Needle vacuum extractor device
Background technology
Swell object under gastrointestinal tract mucosa, such as mesenchymoma, lymthoma, hemangioma etc., it is often necessary to biopsy repeatedly, and conventional endoscopic
Difficult diagnosis, diagnosis rate be not high.With the development of modern technologies, Ultrasonic Diagnosis is attached in scope so that Yi Shengke
To be diagnosed to be using endoscopic ultrasonography, body cavities are more small and lesion of early stage.The diagnosis of any image its correctness is not
On directly to the pathology of tissue chemically examine, therefore, even if after endoscopic ultrasonography enters human body, it was found that be likely to become the portion of lesion
Position, doctor are still more desirable to, using the advantage in pincers road possessed by scope, obtain the living tissue of lesions position, carry out pathology point
Analysis.
In order to obtain the tissue of lesions position, common puncture needle combination endoscopic ultrasonography punctures alimentary canal and its lesion
Suction, to obtain histocyte.Puncture under endoscopic ultrasonography has accuracy strong, safe, patient is painful small, effects of clinic diagnosis
Prominent advantage.However puncture needle has the following disadvantages and defect in the prior art.
First, doctor for convenience, usually selects syringe connecting puncture needle, by the negative pressure of syringe come to puncture needle
Aspirated, and syringe formed negative pressure it is relatively simple, can only qualitative contrlol, cannot quantify be controlled, for different diseases
The tissue of stove, the suction force needed are different, if the negative pressure all formed using syringe aspirates puncture needle, are had
When because negative pressure it is excessive, suction force is big, has extracted excessive tissue, or sometimes because negative pressure is too small, and axis suction is smaller, cannot aspirate
Lesion tissue；
It is manual operation when secondly, because using syringe to form negative pressure, in practical operation work, part lesion is more hard
It is real, it needs to keep vacuum suction to draw more tissues for a long time, this needs operating personnel to have preferable arm strength, muscle power, and obtains
Same position is kept, is changed to prevent the depth and angle of puncture needle.
In addition, sometimes the tissue of suction lesion and the vacuum magnitude assessed in advance have error, this just needs tune appropriate
Vacuum magnitude is saved, i.e. minor adjustments vacuum magnitude makes it preferably take out to obtain required vacuum magnitude in practical operation
Inhale lesion tissue.
In conclusion there is an urgent need for one kind capable of quantifying control vacuum magnitude, it is micro-positioning regulators negative pressure, easy to operate, puncture needle
The puncture needle vacuum extractor device for the quantitative control negative pressure that angle and depth are stablized, and wearing about this quantitatively control negative pressure
Pricker vacuum extractor device.It yet there are no report.
