Abstract
The utility model discloses a kind of puncture cell aspirating device, it is provided with malleation chamber and negative pressure cavity in bitubular main body, is connected with pull bar above the piston in malleation chamber, and rod outer sleeve is equipped with down and pushes away spring; Be connected with push rod above the piston of negative pressure cavity, be provided with below this piston and push away spring; Negative pressure cavity lower end one is aspirated switch and is communicated with needle stand, and lower end one waste cock in malleation chamber communicates with needle stand; Needle stand is connected with puncture fine needle.It only needs control and suck switch and waste cock can reach absorption and the discharge of cell in operation, and convenient to operation, efficiency is higher, avoids fine needle position of puncturing in operation and is shifted, and then ensure that cell draws the accuracy of position.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of puncture cell aspirating device.
Background technology
Fine needle aspiration cytology is by fine needle aspiration focus, draw a kind of cytological diagnostic method that a little cell component makes plate coating checking, there is non-invasive and efficiency advantages of higher, become a medically important diagnostic means at present, especially significant to the diagnosis of tumor.When utilizing Fine needle aspiration cell, its operating procedure is to diseased region by fine needle aspiration, syringe pull bar is pulled back and produces negative pressure, the cell of lesions position is made to be drawn in fine needle, then fine needle is extracted, and it is separated with syringe, be connected with fine needle after making syringe suction air, the absorption thing in fine needle drains on slide by the aerofluxus finally by injection tube again.Aforesaid operations complex steps, comparatively bothers, and efficiency is lower, when especially taking out negative pressure after fine needle thrusts diseased region, needs both hands to operate injection tube, is easy to make fine needle be shifted and cause cell sampling inaccurate, and then affects diagnostic result.
Utility model content
The purpose of this utility model is to provide a kind of structure simple, simple operation, greatly reduces Fine needle aspiration cell difficulty, improves operating efficiency, and is conducive to ensureing to puncture cell aspirating device accurately in sample position.
For realizing above-mentioned technical purpose, this utility model adopts following technical scheme: a kind of puncture cell aspirating device, comprises a bitubular main body; Be provided with all cylindrical, that upper end is open malleation chamber and negative pressure cavity in bitubular main body, in malleation chamber and negative pressure cavity, be respectively equipped with piston; Be connected with pull bar above the piston in malleation chamber, rod outer sleeve pushes away spring under being equipped with downward ejector ram; Be connected with push rod above the piston of negative pressure cavity, be provided with below this piston to provide it and above push away spring to lifting force; Described negative pressure cavity lower end one is aspirated switch and is communicated with needle stand, and lower end one waste cock in malleation chamber communicates with needle stand; Needle stand is connected with puncture fine needle.
This utility model has following beneficial effect: be expert at before puncture, the piston of malleation intracavity is pulled to the top, and is closed by waste cock, and the piston in negative pressure cavity is pushed into bottom, and will aspirate switch closedown; Then i.e. feasible puncture, after puncture fine needle lower end arrives destination locations, open suction switch, piston in negative pressure cavity upper push away the effect of spring under and move up, make negative pressure cavity produce negative pressure; the cell of diseased region is inhaled in puncture fine needle, easily can control vacuum magnitude that negative pressure cavity provides for puncture fine needle and suction time by suction switch, draw thing in puncture fine needle and closes enough afterwards and aspirate switch and puncture fine needle is extracted; Drive shoulder waste cock, the piston in malleation chamber under push away the effect of spring under and move down, make to produce in malleation chamber pressure, so will puncture fine needle in absorption thing discharge, for making slide observe.During owing to operating by this utility model, stored energy has been carried out in advance with negative pressure cavity and malleation chamber, therefore only need control and suck switch and waste cock can reach absorption and the discharge of cell in operation, convenient to operation, efficiency is higher, avoid fine needle position of puncturing in operation to be shifted, and then ensure that cell draws the accuracy of position.

Detailed description of the invention
As shown in Figure 1, the disclosed a kind of puncture cell aspirating device of this utility model, it comprises a bitubular main body 6; Be provided with all cylindrical, that upper end is open malleation chamber 4 and negative pressure cavity 11 in bitubular main body 6, in malleation chamber 4 and negative pressure cavity 11, be respectively equipped with piston 5; Be connected with pull bar 8 above the piston 5 in malleation chamber 4, be equipped with downward ejector ram outside pull bar 8 and push away spring 75 times; Be connected with push rod 9 above the piston 5 of negative pressure cavity 11, be provided with below this piston 5 to provide it and above push away spring 10 to lifting force; Described negative pressure cavity 11 lower end one suction switch 12 communicates with needle stand 2, and lower end one waste cock 3 in malleation chamber 4 communicates with needle stand 2; Described needle stand 2 is connected with puncture fine needle 1.
Be expert at before puncture, the piston 5 in malleation chamber 4 be pulled to the top, and waste cock 3 cuts out, the piston 5 in negative pressure cavity 11 is pushed into bottom, and suction switch 12 cuts out; Then i.e. feasible puncture, after puncture fine needle 1 lower end arrives destination locations, open suction switch 12, piston 5 in negative pressure cavity 11 upper push away the effect of spring 10 under and move up, make negative pressure cavity 11 produce negative pressure; the cell of diseased region is inhaled in puncture fine needle 1, easily can control vacuum magnitude that negative pressure cavity 11 provides for puncture fine needle 1 and suction time by suction switch 12, draw thing in puncture fine needle 1 and closes enough afterwards and aspirate switch 12 and puncture fine needle 1 is extracted; Open waste cock 3, the piston 5 in malleation chamber 4 under push away the effect of spring 7 under and move down, make to produce in malleation chamber 4 pressure, so will puncture fine needle 1 in absorption thing discharge, for making slide observe.
