Abstract
This utility model relates to a kind of disposable gynecological biopsy sampler, be close in the front end of a piston cylinder on end face and be provided with a rotatable arc shear-blade slipping over piston nozzle, blade root is fixed on the front end of supporting revolving shaft, supporting revolving shaft is through piston barrel, its rear portion is exposed the rear end at piston cylinder and is provided with rotating handles, the rear sidewall of piston rod is provided with ladder teeth groove, the cooperation corresponding with the elastic lock be connected on piston cylinder rear end face of this ladder teeth groove.The piston portion of the design can all adopt medical plastic material, convenient manufactures, and cost is low, can single use, and easy to use, will use many well than existing sample pickup tongs.
Description
Technical field
This utility model relates to medical surgical instrument technical field, especially a kind of disposable gynecological biopsy sampler.
Background technology
Cervical biopsy is exactly Cervical biopsy, that is gets a fritter from cervix uteri or a few block organization makes pathologic finding, to determine diagnosis, multiplex have suspicious malignant at cervix uteri, or cervical scraping smear has suspicious cancerous cell, maybe specific inflammation can be suspected to have, as tuberculosis of cervix etc.Cervical biopsy makes a definite diagnosis the most reliable foundation of cervical cancer.No matter be early stage or Advanced Cervical Carcinoma, all must be determined histological type and the cell differentiation of cancerous protuberance by biopsy inspection.Cervical biopsy method is very simple, after sterilization pudendum, vagina, cervix uteri, with a special biopsy forceps, according to diseased region and requirement, Qu Ji little block organization, is placed in 10% formalin solution fixing, Pathology Deparment is sent to cut into slices, after dyeing, basis of microscopic observation analysis, then makes pathological diagnosis.Although the biopsy forceps occurred in the market can sample, when transferring samples in vessel, there is not convenient property, because after cutting sample, sample may stick on biopsy forceps, thus can be more time-consuming during transfer.On the other hand, biopsy forceps mostly is stainless steel, therefore must carry out cleaning and disinfection, to prevent cross-patient contamination when each use.
Summary of the invention
The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, provides a kind of structure simple disposable gynecological biopsy sampler.
This utility model solves the technical scheme that its technical problem adopts: disposable gynecological biopsy sampler, be close in the front end of a piston cylinder on end face and be provided with a rotatable arc shear-blade slipping over piston nozzle, blade root is fixed on the front end of supporting revolving shaft, supporting revolving shaft is through piston barrel, its rear portion is exposed the rear end at piston cylinder and is provided with rotating handles, the rear sidewall of piston rod is provided with ladder teeth groove, the cooperation corresponding with the elastic lock be connected on piston cylinder rear end face of this ladder teeth groove.
The edge rounding off of described piston cylinder front end face, to avoid causing scuffing to patient's vagina and Uterus wall.
During use, strut patient's vaginal orifice with uterus pincers, the front end of this sampler is attached to the position of sampling, draw a lower piston rod, due to suction function, sampled muscular tissue can be sucked a part by piston nozzle, now, the rotating handles of rotary support shaft rear end, blade can streak piston nozzle, the muscular tissue be drawn in piston nozzle is sheared, and blade just in time seals piston nozzle, take out piston cylinder, biopsy has sampled.
The piston portion of the design can all adopt medical plastic material, convenient manufactures, and cost is low, can single use, and easy to use, will use many well than existing sample pickup tongs.
