Description

Biopsy puncture suction rifle

Technical field

The present invention relates to field of medical products, is a kind of biopsy puncture suction rifle specifically.

Background technology

Percutaneous biopsy is the common method of the diseases such as not clear occupying lesion, pleural effusions and ascites and the primary male infertility in clinical diagnosis source, as ultrasound guidance thyroid needle biopsy art, Drug eluting stent art, Percutaneous Renal Biopsy, percutaneous transhepatic puncture biopsy, Transrectal prostatic biopsy, Testes And Epididymides percutaneous biopsy etc.Although along with the progress of ultrasonic technique, solve the accurate location of percutaneous biopsy, avoid wearing the problems such as blood vessel by mistake, but Centesis instrument is still without obviously improving, major part puncture still uses conventional syringe or puncture needle, because of syringe needle or needle length limited cause deep tissue puncture limited, puncture needle cannot once obtain enough tissues and cause repeatedly repeated localised puncture, add patient pain, hemorrhage, the risk infected, simultaneously at hydrothorax, in the puncture suction process of seroperitoneum, conventional use syringe pump, syringe needle is not easily fixed, also cannot indwelling drainage tube, puncture suction is caused to be required great effort, affect suction effect.In addition, in Testes And Epididymides aspiration biopsy process, need 2 doctors to complete, and without suitable Centesis instrument, major part is completed, and there is the tissue mass that punctures out few, needs the problem of repeated localised puncture, add the pain of patient by syringe more.

Summary of the invention

In sum, the object of the present invention is to provide a kind of biopsy puncture suction rifle.

The object of the invention is to be realized by following technology:

A kind of biopsy puncture suction rifle, be made up of nook closing member, stylophore, rifle body lower cover, rifle body upper cover, fixing sheath, spring and hook, stylophore is hollow columnar, and afterbody is funnel-form; Nook closing member entirety is through stylophore, and the syringe needle of its front end exposes; Nook closing member rear end is for holding handle; Hold handle coupling hook; The front end of hook is provided with hoodle; Cover under described rifle body and be provided with hand hole and buckle; Rifle body lower cover is connected with rifle body upper cover is fixed by snap; Fixing sheath is provided with between rifle body lower cover and rifle body upper cover; Rifle body covers and is provided with transparent panel, left side is provided with the outlet of nook closing member stylophore; Nook closing member and stylophore through spring, then through fixing sheath, pass in the outlet of nook closing member stylophore.

Above-mentioned hook is placed in the groove below fixing sheath; The hoodle of hook front end embeds in the lattice shelves in groove.

Above-mentioned transparent panel side is provided with scale.

The funnel-form afterbody of above-mentioned stylophore can be connected with vacuum extractor.

Advantage of the present invention and beneficial effect:

1. the present invention can be different according to the depth position of puncture tissue, and choose nook closing member, the stylophore of different length, than traditional syringe, puncture needle have clinical practice extensively, use advantage flexibly, both can carry out the aspiration biopsy of the deep tissues such as liver, kidney, lungs, also may be used for the aspiration biopsy compared with superficial tissue such as thyroid, Testes And Epididymides, subcutaneous fat tumor.

2. the present invention is in the puncture suction carrying out hydrothorax, seroperitoneum, syringe and puncture needle suction effort and cannot indwelling seal wire, drainage tube, cause aspiration procedure effort, suction effect general, after the puncture of this puncture rifle enters thoracic cavity or abdominal cavity, exit nook closing member, afterbody connects the process that vacuum suction can complete aspirate tissue liquid, simultaneously after suction, after inserting seal wire by stylophore, withdraw from puncture rifle, guided can be inserted drainage tube by seal wire, be convenient to drain residual tissue liquid and censorship.

3. scope of launching of the present invention is between 1-2cm, controllable, complete tissue penetration under ultrasound guidance and there is the advantages such as safety is good, puncturing tissue amount is sufficient, nervus vasculairs can be avoided, can ensure that again enough tissues that punctures out use for biopsy, reduce the operation easier of aspiration biopsy, be also convenient to accurate operation.

4. the present invention once can complete multiple operating function such as biopsy, hydrops suction, and easy easy-to-use, applied range, safety are good, are convenient to dismounting, sterilization, can repeatedly use, reduce medical treatment cost and patient economy burden.
