Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of thyroid needle biopsy device.
Background technology
Thyroid biopsy is the important diagnostic method of diagnosis thyroid pathological changes.While at present thyroid being carried out to biopsy sampling, normally hollow puncture needle is penetrated in thyroid, nook closing member is extracted, to divide leaf thorn to penetrate in puncture needle and sample, operation is trouble comparatively, and sampling amount is less, and be difficult to guarantee once success, to medical work, bring some inconvenience.
Utility model content
For overcoming above-mentioned technical problem, it is a kind of simple in structure that this utility model provides, and aspiration biopsy is easy to operate, the thyroid needle biopsy device that sampling efficiency is high.
For realizing above-mentioned technical purpose, this utility model adopts following scheme: a kind of thyroid needle biopsy device, comprise a puncture tube, and it is characterized in that: described puncture tube front end sealing and be wedge shape, rear end is provided with hollow handle, and puncture needle front end side wall is provided with acquisition port; A nook closing member is penetrated in puncture tube by handle rear end, and the tail end of nook closing member is provided with shank, and the front end of nook closing member is fixed with rubber piston, and the front end of rubber piston is provided with cutting pipe, the sword face that is provided with above of described cutting pipe.When described cutting pipe moves to front end, acquisition port can be sheltered from.
The utlity model has following beneficial effect: during puncture, first nook closing member is pushed in puncture tube completely, cutting pipe outer wall is sheltered from acquisition port, then can puncture, after puncturing successfully, by shank, pull back nook closing member, now rubber piston and cutting pipe move backward, make piston nose form negative pressure, when cutting pipe is while moving to acquisition port rear, parathyroid tissue stretches in acquisition port under suction function, then promotes shank and makes to cut pipe and move forward, portion of tissue is cut, finally puncture tube is extracted.It is rational in infrastructure, easy to operate, and biopsy sampling efficiency is high, totally closed operation, and safety and sanitation, have significant practicality.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
The specific embodiment
Shown in Fig. 1, a kind of thyroid needle biopsy device, comprises a puncture tube 3, it is characterized in that: described puncture tube 3 front ends seal and are wedge shape, and rear end is provided with hollow handle 5, and puncture needle 3 front end side wall are provided with acquisition port 1; A nook closing member 4 is penetrated in puncture tube 3 by handle 5 rear ends, and the tail end of nook closing member 4 is provided with shank 6, and the front end of nook closing member 4 is fixed with rubber piston 2, and the front end of rubber piston 2 is provided with cutting pipe 7, the sword face 8 that is provided with above of described cutting pipe 7.When described cutting pipe 7 moves to front end, acquisition port 1 can be sheltered from.
