Abstract

The utility model discloses a biopsy rifle comprises main part and biopsy needle part, the biopsy needle part comprises puncture nook closing member (1) and concentric sleeve pipe (2), puncture nook closing member (1) is fixed casing (3) of main part cavity in on the pjncture needle core print seat, and sleeve pipe (2) are fixed on the casing seat in casing (3) of main part cavity with one heart, the rounded shape coating structure for the knee space of the front seat is characterized in that, puncture nook closing member (1) do not get the real core needle of organizing the recess for straight not the taking of front end, puncture after the pulling is tied nook closing member (1) and concentric sleeve pipe (2) front end length parallel and level, touch the trigger after concentric sleeve pipe (2) front end compare the long 2cm of nook closing member (1) that punctures, have simple structure, convenient operation, accuracy and efficient characteristics, improve the quality and quantity of biopsy specimen, guarantee the clinical tissue success of getting, can also reduce the misery of patient and infant, be favorable to popularizing and applying.

Description

A kind of cell taking gun

Technical field:

This utility model relates to technical field of medical instruments, specifically a kind of cell taking gun；It is mainly used in puncturing and obtains biopsy specimen.

Background technology:

Bone and soft tissue tumors is the disease of serious harm human health and life, and sickness rate is gradually increasing in recent years, and age of onset is gradually reduced, and prognosis is had important impact by early discovery, correct diagnosis, in time treatment.Along with improving constantly of detection methods and method, make the accuracy of diagnosis gradually step up, but still have tumor greatly not possess typical Imaging Features, difficult diagnosis.Correct diagnosis needs clinic, image and pathology three combination.Wherein, the selection of therapeutic scheme is played pivotal role by pathological diagnosis.Aspiration biopsy is the main path obtaining pathological diagnosis, improves accuracy rate generally by biopsy, and when this is to biopsy, the quantity of tissue there are certain requirements.nullExisting cell taking gun is made up of main body and biopsy needle two parts，Main part includes housing，The both sides of housing have hands to pull hole respectively，Housing is formed by two halves docking，Puncture needle core print seat and casing seat is had in the cavity of housing，Puncture needle core print seat front end has and has hook up and down，Casing seat upper and lower surface has two projections respectively，Interval 1cm，Puncture needle core print seat can move in cavity，Hook can hang in projection，Puncture needle core print seat fixes puncture needle core，Fixed sleeving on casing seat，Puncture needle core enters in sleeve pipe through the centre bore of casing seat，Puncture needle core outer casing spring between puncture needle core print seat and casing seat，Cushion pad is had between casing seat and housing hollow inwall，Its puncture needle core front end is than set pipe range 2cm，Nook closing member front end band groove，Undertaken taking tissue by groove，It is more scrappy that this mode obtains tissue，Tissue mass is less，Impact obtains positive rate and the rate of correct diagnosis of tissue，Incorrect biopsy can to the consequence of bringing on a disaster property of patient.

Utility model content:

The purpose of this utility model is the deficiency overcoming above-mentioned prior art, and provides a kind of cell taking gun；Mainly solve existing cell taking gun and take the problem that tissue mass affects positive rate and the rate of correct diagnosis obtaining tissue less.

The technical solution of the utility model is: a kind of cell taking gun, is made up of main part and biopsy needle part；Biopsy needle part is made up of puncture needle core and concentric tubes；Puncture needle core is fixed in the housing hollow of main part on puncture needle core print seat, and concentric tubes is fixed on the casing seat in the housing hollow of main part；It is characterized in that, described puncture needle core is that front end is straight without the real core needle taking tissue groove, and after pulling bolt, puncture needle core is concordant with concentric tubes front end length, concentric tubes front end 2cm longer than puncture needle core after shake-up trigger.

Compared with the prior art a kind of cell taking gun described in the utility model has following good effect, 1, the concordant puncture needle core of front end length and concentric tubes are adopted, tissue can be directly taken with concentric tubes, that takes out is organized as strip, tissue is taken than the groove in existing employing puncture needle core, substantially increase the quantity of tissue, thus improving the accuracy of positive rate and the diagnosis obtaining tissue；2, there is simple structure, easy to operate, accurate and high efficiency feature, improve the quality and quantity of biopsy specimen, it is ensured that clinic takes tissue success, moreover it is possible to reduces the misery of patient and infant, is conducive to popularization and application.

Accompanying drawing illustrates:

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention:

In order to be more fully understood that and enforcement, provide specific embodiment below in conjunction with accompanying drawing and describe this utility model in detail；Illustrated embodiment is only used for explaining this utility model, is not intended to limit scope of the present utility model.

Embodiment 1, referring to Fig. 1, prior art is adopted to be processed into main part, puncture needle core print seat and casing seat is had in housing 3 cavity of main part, puncture needle core 1 is fixed on puncture needle core print seat, concentric tubes 2 is fixed on casing seat, biopsy needle part is formed by puncture needle core 1 and concentric tubes 2, puncture needle core 1 is that front end is straight without the real core needle taking tissue groove, after pulling bolt, puncture needle core 1 is concordant with concentric tubes 2 front end length, concentric tubes 2 front end 2cm longer than puncture needle core 1 after shake-up trigger.

A kind of cell taking gun described in the utility model, during use, touches trigger generation fast kicking power and makes concentric tubes enter tissue, concentric tubes takes tissue, then pulls bolt, and the tissue in concentric tubes is released outside concentric tubes by puncture needle core, it is organized as strip, completes biopsy and take tissue.

Claims

1. a cell taking gun, is made up of main part and biopsy needle part；Biopsy needle part is made up of puncture needle core (1) and concentric tubes (2)；Puncture needle core (1) is fixed in housing (3) cavity of main part on puncture needle core print seat, and concentric tubes (2) is fixed on the casing seat in housing (3) cavity of main part；It is characterized in that, described puncture needle core (1) is straight without the real core needle taking tissue groove for front end, and after pulling bolt, puncture needle core (1) is concordant with concentric tubes (2) front end length, concentric tubes (2) front end 2cm longer than puncture needle core (1) after shake-up trigger.
