Abstract

The utility model provides a puncturing cell attracter, which comprises a pinhead with edge, a cover and a core-bar, and other members around the bevel. An inner-concave sidestep which is provided with cell tissue filter-film is arranged at the front of the wimble hole of the cover. The different parts of the middle of the core-bar are provided with negative-voltage locking holes; the perforating casing of an end of the push-and-pull shelf is periphery of the cover, and the bayonet at the other side is clipped on the core-bar of the inner side of the handle. The negative-voltage locking hole of the core-bar can lock negative voltage, and operators can deeply feel the prickly feeling by hold the part that is close to the pinhead so as to judge whether the tumour is benign or malignant. The inner-concave sidestep of the wimble hole of the cover is stuck with cell tissue filter-film, and the pinhead can be pulled out with negative voltage so that not only the cancer cell can avoid falling onto the spinal path or endermic parts of the cancer cell which leads to manual planting, but also the spinal objects can avoid spurting into the cover which affects the check. Compared with prior art, the utility model can take out negative voltage under single-hand operation, and sample-taking is simple, swift and safe and with high efficiency; besides, the cancer cells can be centralized-collected, which makes the check easier.

Description

Puncture cell extractor

Technical field

This utility model belongs to fine needle and draws a kind of instrument that cytolgical examination is drawn materials.

Background technology

Human life and health in current cancer serious threat, and people often are called second largest killer, how to save cancer patient's life and health, and unique effective measures are early diagnosiss, the early treatment.Cancer diagnosis method the most accurately is the method for histopathology and pathocytology.Though the histopathology diagnosis accurately, need operate on and get tissue, the time is long, expense is high, damage is big.Cytological method is easy relatively fast, and accuracy is also very high.Cytological inspection, still multi injector is done absorption at present.Facts have proved that doing absorption with syringe has a lot of problems, not high as make absorption efficient of syringe, usually inhale cell less than pathological changes.Syringe is done to draw often needs bimanualness, left hand to hold up overcoat right hand depoling bar effort inconvenient again.Do the negative pressure that to come loose when pin is pulled out in absorption with syringe, can make the carcinoma cell detachment, cause artificial growth at needle track and subcutaneous.Puncture cell extractor is at above-mentioned problem and the custom-designed cell instrument of drawing materials.Syringe needle is through special processing, beveled aperture week the band sharp sword, after pin entered pathological tissues, can scraping more cell through left rotation and right rotation, to enter the pin hole amount of drawing materials bigger.Secondly outer putting is equipped with the ring type pushing-pulling-rack and is convenient to the singlehanded nimble negative pressure of taking out, and left hand is lump fixedly, singly takes out negative pressure with the right hand, not only draw materials accurately, some positions such as oral cavity, anus, intravaginal pathological changes are arranged, and because of left hand will be operated dilator, syringe is singlehanded just can't be drawn.

Summary of the invention

Goal of the invention of the present utility model is to provide a kind of easy, quick, safe, cell extractor that punctures efficiently.

The technical solution of the utility model is formed puncture cell extractor by the syringe needle of being with sharp sword beveled aperture week, overcoat, core bar etc.Outer taper hole front end has an indent step, and the cell tissue filter membrane is housed in the indent step; The diverse location at core bar middle part has the negative pressure lockhole, pins the negative pressure of different sizes in the extractor as required; The circle hole sleeve of ring type pushing-pulling-rack one end is in the periphery of overcoat, and the bayonet socket of the other end is stuck on the core bar of pressing the hands inboard.

Core bar overcoat material is plastics, and the puncture needle material is for making the medical apparatus and instruments stainless steel tube, and the cell tissue filter membrane is medical filter membrane.

Core bar of the present utility model has the negative pressure lockhole, can pin negative pressure, the right hand can be held the position near syringe needle, be convenient to deep cognition pin sense, help to judge the good pernicious matter of tumor, the sticking cell tissue filter membrane that is placed with on the front end concave station rank, cell extractor outer taper hole particularly punctures, can be with negative pressure to pull out syringe needle, both can avoid cancerous cell to be shed to needle track or subcutaneous, cause artificial growth, can avoid pin to inhale thing again and under suction function, spray into influence inspection in the overcoat, because of filter membrane being arranged under suction function, can be sprayed on the cancerous cell in the pin hole surface of filter membrane, play the effect of centralized collection cancerous cell.

This utility model compared with prior art can the singlehanded nimble negative pressure of taking out, draw materials easy, quick, security effectiveness is high.

Description of drawings

Accompanying drawing is puncture cell extractor assembling sketch map;

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing is described in further detail this utility model:

In the accompanying drawing, syringe needle 1, core bar 10, overcoat 6, the cell tissue filter membrane 3 of puncture cell extractor beveled aperture week band sharp sword, plug 5 and ring type pushing-pulling-rack 7 are formed.Be with needle guard 2 on the syringe needle 1.Beveled aperture week band sharp sword left rotation and right rotation in pathological tissues of syringe needle 1 can be drawn than many cells and improve the effect of drawing materials.Overcoat 6 cone head hole internal diameters are 1.5mm, and the diameter that has of cone head hole front end is the indent step 12 of 3mm, dark 0.2mm, glue in the indent step 12 to be placed with the cell tissue filter membrane 3 that diameter is 3mm, thick 0.3mm, and the surperficial little of film gives prominence to.The diverse location at core bar 10 middle parts is provided with three pairs of negative pressure lockholes 8, when puncture, can insert in the negative pressure lockhole 8, pin negative pressure, make the right hand hold the position of close syringe needle with the thin end of needle guard 2, be convenient to deep cognition pin sense, help to judge the very pernicious of tumor.The circular hole 13 of ring type pushing-pulling-rack 7 one ends is enclosed within the periphery of overcoat, the bayonet socket 14 of the other end is stuck on the core bar 10 of pressing hands 11 inboards, during use, withstand overcoat 6 crimpings with thumb, during with the forefinger and the middle finger draw-ring type pushing-pulling-rack butterfly wing, core bar 10 moves backward and forms negative pressure absorption cell, realizes one-handed performance like this.

One end of annular pushing-pulling-rack 7 has the butterfly wing, one circular hole 13 is arranged in the butterfly wing, the slightly larger in diameter of circular hole 13 is in the overcoat external diameter of adapted, and the other end of annular pushing-pulling-rack 7 has one can be the support of annular pushing-pulling-rack by the

bayonet socket

14,15 that the core bar of hands inboard blocks mutually with the extractor of institute adapted.
