Description
Technical field
This utility model relates to medical apparatus and instruments ancillary technique field, especially a kind of tumor needle tube type sampler.
Background technology
Tumor needle tube type sampler is a kind of instrument conventional in adopting tumor biopsy, penetrates tumor locus, takes the liquid of lesion to chemically examine, enable doctor more understand the patient's condition and the therapeutic effect of patient by syringe needle.
But use maximum employing devices mainly to sample to the liquid of neoplastic lesion tissue at present, cannot sample to the solid tissue of pathological changes, liquid only by detecting extraction Chu can not understand the pathological changes situation of pathological tissues and the later stage carries out the treatment situation of chemotherapy to pathological tissues accurately, make doctor can not understand the state of an illness of patient timely, be easy to delay best therapic opportunity.
Utility model content
The technical problems to be solved in the utility model is: can not take solid tissue's sample and liquid sample problem easily to solve existing tumor sampler simultaneously, this utility model provides a kind of tumor needle tube type sampler, adopt fluid apertures by arranging in needle body part and adopt solid projection, effectively solving existing tumor sampler can not take solid tissue's sample and liquid sample problem easily simultaneously.
This utility model solves the technical scheme that its technical problem adopts: provide a kind of tumor needle tube type sampler, comprise stopper rod, piston, plug tube and syringe needle, stopper rod is fixedly connected with piston, piston be arranged on plug tube inside and with plug tube inwall close contact, plug tube is communicated with syringe needle, described syringe needle comprises needle body part and needle tip, described needle body part is cavity structure, described needle body part is provided with adopts fluid apertures and adopts solid projection, the described cavity connects adopted fluid apertures and adopt solid projection and needle body part, describedly adopt solid projection and comprise the thief hatch for cutting solid tissue and the blade for cutting off solid tissue, the direction of described thief hatch is the circumferencial direction of needle body part, described blade is arranged in thief hatch, described needle tip is solid construction.
Particularly, described in adopt in fluid apertures and be fixed with anti-network blocking, prevent solid tissue from blocking and adopt fluid apertures, cause getting liquid difficulty, do not reach the object of getting liquid.
Particularly, described in adopt solid projection and be arranged near needle tip, described in adopt fluid apertures and be arranged on the top of adopting solid projection, the solid tissue taked enters in the cavity of needle body part, prevents sampling from too much causing adopting fluid apertures blocking.
Further, described blade is fixedly connected with needle body part is vertical, and described blade is arranged on thief hatch inside on the lower, and rotating needle sampling Solid State Structure, after sampling completes, directly extract syringe needle, blade directly can cut off Solid State Structure.
The beneficial effects of the utility model are: a kind of tumor needle tube type sampler that this utility model provides, simple structure, easy to operate, solid tissue and liquid sample can be taked very easily, also can prevent from adopting fluid apertures blocking, make to get liquid more convenient, greatly saved the time of doctor's sampling, improve the work efficiency of doctor.
