The traditional puncture biopsy mainly comprises palpating pathological tissues by a manipulation, inserting a puncture needle into a focus, repeatedly sucking to obtain histopathological diagnosis, and has the defects of simple and convenient method, less material taking amount, insufficient experience or improper material taking part, multiple times of puncture, difficulty in penetrating into a tumor area or obtaining representative tumor tissues, difficulty in obtaining accurate conclusions and even making wrong conclusions.
The puncture biopsy under the ultrasonic guidance has the advantages of high accuracy rate of 98.4 percent, no radiation, clear display of information such as lymph node position, structure and the like, realization of accurate and targeted puncture effect on hidden lymph nodes, improvement of diagnosis accuracy and avoidance of damage to other tissues and organs (blood vessels, nerves, tracheas and the like).
The non-negative pressure fine needle aspiration biopsy (FNAC) is a cytological examination method for sucking out a small amount of cell components in suspicious lymph nodes by fine needle aspiration under the guidance of ultrasound, and observing whether tumor cell morphological changes exist in the lymph nodes by smear, and has the advantages of safety, simple operation, easy tolerance and the like, the defects of easy occurrence of false negative or insufficient material taking, failure of providing histological information, poor differentiation of pathological layers (infiltration depth), and the coarse needle aspiration biopsy (CNB) is a histological examination method.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a supplementary suction device of fine needle puncture vacuum under the supersound guide to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
thin needle puncture vacuum auxiliary suction device under supersound guide, the power distribution box comprises a box body, the bottom sliding connection of box inner chamber has the second storing box, and the syringe has been placed to the inner chamber of second storing box, the middle-end fixedly connected with baffle of box inner chamber, and the top sliding connection of baffle has first storing box, the pjncture needle has been placed to the inner chamber of first storing box, and the equal fixed mounting in middle-end on first storing box and the positive surface of second storing box has the handle, the middle-end fixedly connected with display at box top, and the left lower extreme of display is connected with ultrasonic transducer through the wire.
Compared with the prior art, the beneficial effects of the utility model are as follows:
the utility model discloses both can satisfy pathological material quantity (the cell of once drawing materials and tissue volume ten times for FNAC), but also real-time observation lymph gland structure and positional information, the complication is few, the security is high, easy and simple to handle, repeatability is good, unite cell wax stone technique simultaneously, pathological diagnosis and disease staging can finally be made clear and definite, provide the foundation for formulating treatment plan and appraising prognosis, and can clearly show focus and surrounding anatomical structure relation between the neck tissue, make traditional cytology diagnosis rise to cell-histology diagnosis level, for immunohistochemistry, genetic testing, pathological diagnosis is made clear and definite, disease analysis and molecular detection etc. provide good sample platform, compare with the thick needle puncture, the thin needle puncture has following advantage: only a common syringe is needed to be used, the adaptability of the syringe is improved, the puncture cost of the syringe is reduced, and meanwhile, a needle head used for puncturing by a fine needle is the needle head of the syringe which is generally used clinically, so that the stimulation to tissues is small.
