Description
Technical field
This utility model relates to medical instruments field, is specifically a kind of Novel renal puncture needle.
Background technology
In diagnosis of nephropathy therapeutic process, renal puncture biopsy is a kind of method judging nephropathy type.Need with puncture needle during renal puncture biopsy, existing puncture needle can not control the degree of depth punctured, and be difficult to ensure primary sample success, use inconvenience, efficiency is low.In view of this, Chinese patent 201320853533.5 discloses a kind of kidney biopsy puncture needle, comprise puncture needle tubing, described puncture needle tube-surface is evenly provided with graduation mark, described puncture syringe rear end arranges tapered needle seat, described puncture syringe rear end is connected with joint portion, syringe front end, is provided with push rod in described syringe, and described push rod front end is provided with the Rubber end be connected with cylinder piston.This utility model, by arranging graduation mark at puncture needle tube-surface, accurately can control paracentesis depth, easy to use, and Biopsy success rate is high.But after having extracted tissue fluid, need tissue fluid to be injected in storage capsule, there is following problem like this: be 1. injected in storage capsule process by the tissue fluid of extraction, impurity or antibacterial enter into the tissue fluid of extraction, affect test effect; 2. doctor uses inconvenience, and work difficulty is large.
Utility model content
Problem to be solved in the utility model is to provide a kind of Novel renal puncture needle, can rapidly tissue fluid be injected in storage capsule after using the tissue fluid in this utility model extraction kidney, avoid the tissue fluid that impurity or antibacterial enter into extraction, use and also facilitate, reduce the work difficulty of doctor.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of Novel renal puncture needle, comprise puncture needle tubing, the surface uniform of described puncture needle tubing is provided with graduation mark, this puncture needle tubing is connected with syringe, piston is provided with in described syringe, described piston is connected with push-pull bar, it is characterized in that: the junction of described puncture needle tubing and described syringe is provided with the first check valve, described push-pull bar is hollow tubular, the end of this push-pull bar is removably connected with storage capsule by connection tube, described piston is provided with the second check valve with described push-pull bar junction.
Preferably, above-mentioned Novel renal puncture needle, wherein said puncture needle tubing is provided with baffle plate.
Preferably, above-mentioned Novel renal puncture needle, the inwall of wherein said puncture needle tubing is provided with multiple arc-shaped convex, is sealed with liquid in described arc-shaped convex.
Preferably, above-mentioned Novel renal puncture needle, wherein said connection tube is flexible pipe, and this connection tube is provided with control valve.
Preferably, above-mentioned Novel renal puncture needle, wherein said storage capsule is provided with import, and described connection tube and described import removably connect.
Preferably, above-mentioned Novel renal puncture needle, wherein said storage capsule hangs with the lid matched with described import by line body.
Technique effect of the present utility model is mainly reflected in: the surface uniform of puncture needle tubing is provided with graduation mark, accurately can control paracentesis depth; After having extracted the tissue fluid in kidney, compress push-pull bar inwardly, the tissue fluid of extraction directly can enter into storage capsule through push-pull bar and connection tube from syringe, avoids impurity or antibacterial to enter into the tissue fluid of extraction; Doctor continuously from extracting interstitial fluid in kidney, can avoid secondary contact pin, easy to use, reduces work difficulty; Puncture needle tubing is provided with baffle plate, makes the better controlling depth of doctor; The tissue fluid extracted enters into storage capsule, and connection tube of dismantling can cover lid in import department, avoids impurity or antibacterial to enter into the tissue fluid of extraction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The longitudinal sectional view of the puncture needle tubing in Fig. 2 this utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is told about further, be easier to make the technical solution of the utility model understand and grasp.
As shown in Figure 1, 2, a kind of Novel renal puncture needle, comprises puncture needle tubing 1, and the surface uniform of puncture needle tubing 1 is provided with graduation mark 11, and doctor accurately can control paracentesis depth by graduation mark 11.Puncture needle tubing 1 is connected with syringe 2, piston 3 is provided with in syringe 2, piston 3 is connected with push-pull bar 4, puncture needle tubing 1 is provided with the first check valve 5 with the junction of syringe 2, push-pull bar 4 is hollow tubular, and the end of this push-pull bar 4 is connected with storage capsule 7 by connection tube 6, storage capsule 7 is provided with import 71, connection tube 6 and import 71 removably connect, and on piston, 3 are provided with the second check valve 8 with push-pull bar 4 junction.
Wherein puncture needle tubing 1 is provided with baffle plate 9, makes the better controlling depth of doctor.The inwall of puncture needle tubing 1 is provided with multiple arc-shaped convex 12, and be sealed with liquid in arc-shaped convex 12, this liquid is water, and ultrasound wave is not reflection in water, forms good sound transmitting window, is conducive to doctor and grasps inserting needle situation.Connection tube 6 is flexible pipe, and this connection tube 6 is provided with control valve 61, can throttling in time.Storage capsule 7 hangs with the lid 10 matched with import 71 by line body, the tissue fluid of extraction enters into storage capsule 7, and connection tube 6 of dismantling can cover lid 10 at import 71 place, avoids impurity or antibacterial to enter into the tissue fluid of extraction.
When doctor uses, be inserted in kidney by puncture needle tubing 1, stretch out push-pull bar 4, the first check valve 5 is opened, and the second check valve 8 is closed, and the tissue fluid in kidney can enter into syringe 2; Compress push-pull bar 4, first check valve 5 inwardly to close, the second check valve 8 is opened, and the tissue fluid of extraction can directly enter into storage capsule 7 through push-pull bar 4 and connection tube 6 from syringe 2, avoids impurity or antibacterial to enter into the tissue fluid of extraction; Doctor continuously from extracting interstitial fluid in kidney, can avoid secondary contact pin, easy to use, reduces work difficulty.
Certainly, the exemplary illustration of the above only this utility model typical apply, by the combination of same or similar technical characteristic and replacement, can form multiple concrete scheme, these schemes all drop within protection domain of the present utility model.
