Abstract
The utility model relates to a medical puncture needle, which belongs to the field of the medical appliance. The medical puncture needle comprises a needle tube, a needle core and a negative pressurecore, and is characterized in that the front end of the needle tube is provided with a serrated knife, the rear end of the needle tube is connected with a syringe, the tip of the needle core is in a needle point shape, the needle core can be inserted in the needle tube and protrudes out of the needle tube, and the negative pressure core is a straight rod which can be inserted in the needle tube and is shorter than the needle tube. The utility model has a simple structure, and can extract the bone marrow and living tissue, greatly improve the success rate of puncture sampling, and reduce the pains of the patient and also the workload of the medical staff.
Description
Technical field
This utility model relates to the medical apparatus field, at length says it is the medical puncture needle that a kind of pathological biopsy is used.
Background technology
As everyone knows, puncture needle is a medical apparatus commonly used when carrying out pathological diagnosis, desirable bone marrow fluid and living tissue.Mostly the puncture needle of hospital application is the staight needle pipe at present, syringe needle is straight and smooth, it is unreliable to take a sample, primary sample is unsuccessful, needs repeatedly sampling, has increased patient's pain and misery, strengthened medical worker's workload, and the puncture needle of puncture bone marrow is less because of internal diameter again, can only get bone marrow fluid, can not get living tissue.
Summary of the invention
In order to overcome the deficiencies in the prior art, this utility model provides a kind of medical puncture needle, and is simple in structure, not only desirable bone marrow fluid but also desirable living tissue, and improve puncture sampling success rate greatly, and reduce patient's misery, alleviate medical worker's workload.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of medical puncture needle, be provided with needle tubing, nook closing member and negative pressure core, it is characterized in that: the front end of needle tubing is provided with serrated knife, syringe rear end links to each other with syringe, the syringe needle of nook closing member is tip-like, nook closing member can insert in the needle tubing and protrude in outside the needle tubing, and the negative pressure core is one can insert the straight-bar in the needle tubing, and the negative pressure core is shorter than needle tubing.
The beneficial effects of the utility model are, and are simple in structure, not only desirable bone marrow fluid but also desirable living tissue, and improve puncture sampling success rate greatly, and reduce patient's misery, alleviate medical worker's workload.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1, the structural representation of this utility model needle tubing.
Fig. 2, the structural representation of this utility model nook closing member.
Fig. 3, the structural representation of this utility model negative pressure core.
1. needle tubings among the figure, 2. serrated knife, 3. nook closing member, 4. negative pressure core.
The specific embodiment
In Fig. 1, Fig. 2, Fig. 3, this utility model is provided with needle tubing 1, nook closing member 3 and negative pressure core 4, the front end of needle tubing 1 is provided with serrated knife 2, needle tubing 1 rear end links to each other with syringe, and the internal diameter of needle tubing 1 is designed to 18mm, and the syringe needle of nook closing member 3 is tip-like, nook closing member 3 can insert in the needle tubing 1 and protrude in outside the needle tubing 1, negative pressure core 4 is one can insert the straight-bar in the needle tubing 1, has a bossing to prevent that it from falling on the bar in needle tubing 1, and negative pressure core 4 is shorter than needle tubing 1.
This utility model in use, earlier nook closing member 3 is inserted needle tubing 1, connect syringe, with this needle tubing 1 puncture tissue or bone marrow, the needle point puncture of nook closing member 3 easily, nook closing member 3 protrudes in outside the needle tubing 1, bring normal structure in the time of can avoiding puncturing in needle tubing 1, when needle tubing 1 reaches the need sampling point, nook closing member 3 is taken out, change negative pressure core 4, negative pressure core 4 is shorter than needle tubing 1, makes the fore-end of needle tubing 1 that certain space be arranged, and utilizes syringe to bleed and causes negative pressure, rotate needle tubing 1, the serrated knife 2 of needle tubing 1 front end can cut living tissue, the suction function in the needle tubing 1, sampling success rate height when needle tubing 1 is extracted out, stopping of negative pressure core 4, avoid biopsy when negative pressure, to enter the upper end of needle tubing 1.Not only desirable bone marrow fluid of puncture needle of the present utility model but also desirable living tissue, and improve puncture sampling success rate greatly, reduce patient's misery, alleviate medical worker's workload, the clinical treatment effect is better.
