Description
Technical field
This utility model relates to a kind of extractor, specifically a kind of tumor cell extractor.
Background technology
Biopsy is called for short " biopsy ", also known as surgical pathology inspection, is called for short " examining outward "; Refer to the needs should diagnosed, treat, cut in patient body, clamp and to get or pathological tissues is taken out in puncture etc., carry out the technology of pathological examination.This is most important part in Diagnosis pathology, can make clear and definite histopathologic diagnosis to most censorship case, by as clinical final diagnosis.At Internal Medicine-Oncology, need clinically to carry out biopsy to patient.Biopsy from biological tissue, gets a fritter exactly or pathologic finding does in a few block organization, since analyze its tissue change situation so that determine diagnosis.Medical worker carries out biopsy sampling to patient, and the general syringe that adopts thrusts inside tumor suction extraction sample.But this method complex operation, wastes time and energy extremely inconvenient.
Utility model content
The purpose of this utility model is to provide a kind of tumor cell extractor, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme:
A kind of tumor cell extractor, comprise hollow puncture needle tubing, liquid containing bottle and liquid extracting device, the lower end of described hollow puncture needle tubing is provided with solid piercing needle, the side, lower end of hollow puncture needle tubing is provided with tumor tissues thief hatch, the inside of hollow puncture needle tubing is provided with tumor tissues sampler, and tumor tissues sampler is connected with manual rotation nut by connecting rod; Described tumor tissues sampler is cylindrical structural, and its arranged outside has several tumor tissues scraper, and the inner side of tumor tissues scraper is provided with tumor tissues collecting tank; The top left hand of described hollow puncture needle tubing is provided with liquid-pumping nozzle, liquid-pumping nozzle is connected with drawing liquid conduit, drawing liquid tubes connection has liquid containing bottle, liquid containing bottle is by unidirectional Kong Eryu drawing liquid tubes connection, and unidirectional Kong Eryu catheter is connected, and liquid containing bottle inside is provided with cotton swab plate, perforate is provided with above cotton swab plate, be inserted with cotton swab inside perforate, liquid containing bottle side is provided with unidirectional hole one, unidirectional hole one is connected with the union joint of liquid extracting device.
Further, described liquid extracting device is provided with graduated scale.
Further, inside, described unidirectional hole one is provided with check valve.
Compared with prior art, when this utility model uses, first the needle tubing that hollow punctured is inserted in tumor, then manually swivel nut drives tumor tissues sampler to rotate, tumor tissues sampler is scraped by tumor tissues scraper and is collected in tumor tissues collecting tank from some cell tissue, is then extracted out by tumor tissues sampler, when needing the tissue fluid extracting tumor, liquid extracting device is inserted in the unidirectional hole one bottom liquid containing bottle by the union joint of front end, wherein inside, unidirectional hole one is provided with check valve, can only one direction insert, and when union joint is extracted, check valve is closed immediately, the drawing liquid conduit being connected with syringe needle is inserted the unidirectional hole two on the bottle stopper of liquid containing bottle, make liquid extracting device, liquid containing bottle, drawing liquid conduit is connected with syringe needle sealing, syringe needle is inserted into the position need taking out hydrops, pull the piston of liquid extracting device, the negative pressure produced makes hydrops enter in liquid containing bottle along drawing liquid conduit, after drawing liquid, extract liquid extracting device and drawing liquid conduit, by liquid containing bottle censorship, when testing, unplug bottle stopper, take out from cotton swab plate the cotton swab being moistened with sample liquid to test, structure is simple, combine interspersed pin, achieve inside tumor collection, wound is little, danger coefficient is little, the tissue fluid of tumor can also be extracted simultaneously.
Accompanying drawing explanation
