Abstract
The utility model provides a novel drainage needle belonging to a medical apparatus. The novel drainage needle is provided with a puncture needle core; one end of the puncture needle core is provided with a needle bed, and the other end of the puncture needle core is an inclined plane; a flexible outer sleeve is sleeved outside the puncture needle core; and the end part of the outer sleeve is provided with a side hole which is arranged at the same side with the inclined plane on the puncture needle core. The drainage needle has the advantages that the puncture needle core is drawn out after successful puncture, while the flexible outer sleeve is retained in the body of a patient to be used for drainage operation, thus, the opposite side wall of a nodule and other tissues are not easily punctured during operation, and high safety in use is achieved; and the patient is allowed to change the body position in the drainage process so as not to feel fatigable.
Description
Technical field
This utility model relates to a kind of medical appliance, relates in particular to a kind of drain apparatus.
Background technology
At present, when patient's cyst is carried out drain, because puncture needle is the stainless pin of band needle point, wear out the oppose side wall and the hetero-organization thereof of cyst easily during operation, the safety of use is low, and in the drain process, patient will keep position constant, is easy to fatigue by mistake.
Summary of the invention
This utility model technical problem to be solved is a kind of novel drainage needle to be provided, to improve the safety of using.
This utility model be realize like this, novel drainage needle, it has the puncture nook closing member; One end of puncture nook closing member is that needle stand, the other end are the inclined-plane; The outside of puncture nook closing member is set with flexible trocar sheath, and there is side opening the end of trocar sheath, and side opening is positioned at the same side on the inclined-plane on the puncture nook closing member.
Adopt the drainage needle of said structure; The nook closing member that will puncture after puncturing is successfully extracted out and the trocar sheath of flexibility is retained in carried out drainage procedure in the patient body; Be difficult for mistake during operation and wear out the oppose side wall and the hetero-organization thereof of cyst; That uses is safe, and allows patient posture change, indefatigability in the drain process.
Description of drawings
Fig. 1 is the sketch map of this utility model structure.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing explains the concrete structure of this utility model.
Shown in accompanying drawing, the novel drainage needle of this utility model, it has puncture nook closing member 2; One end of puncture nook closing member is that needle stand 5, the other end are the inclined-plane; The outside of puncture nook closing member is set with flexible trocar sheath 3, and there is side opening 4 end of trocar sheath, and side opening is positioned at the same side on the inclined-plane on the puncture nook closing member.
During use, under the guiding of CT scan, will puncture nook closing member and trocar sheath puncture in patient's cyst together.After puncture was accomplished, the nook closing member that will puncture was extracted out, and trocar sheath is stayed in the patient body.After this can connect syringe in telescopic outside outer end, operations such as the suction of completion cyst or injection medicine.
On the needle stand of puncture nook closing member, convexity 1 can be arranged, convexity is positioned at the same side, inclined-plane on the puncture nook closing member.Can play indicative function like this, be convenient to judge the inclined-plane towards.
