Abstract
The utility model belongs to a thoracicpuncture needle, which aims to overcome shortcomings that at present, frequently-used thoracicpuncture needle is easy to be blocked by floaters in chest fluid or re-expanded lung tissues, drainage is unsmooth and the lung tissues are easy to be punctured. A double-layered trocar is adopted, and the front end of an outer-layer trocar is a sharp needle tip and can puncture the chest wall of a patient. An 'L'-shaped clamp groove is arranged at the tail of the thoracicpuncture needle, the 'L'-shaped clamp groove and a bolt at the tail of an inner-layer trocar form a limiter, and the locations of the inner-layer trocar and the outer-layer trocar can be indicated and fixed. The front end of the inner-layer trocar is a flat head, and the lung tissues are prevented from being injured. A side hole is reserved at the front end of the thoracicpuncture needle so that the thoracicpuncture needle is prevented from being blocked by foreign matters. The thoracicpuncture needle can realize smooth drainage, simultaneously, minimizes lung tissue puncturing risks and is safe.
Description
Affiliated technical field
This utility model belongs to a kind of medical apparatus and instruments.
Background technology
Thoracentesis is clinical medical diagnosis and treat commonly used technology.Thoracic-puncture needle commonly used at present is a single hole tip draw point, and the defective one of its existence is that the single hole needle point is stopped up by floating thing in the chest fluid or multiple lung tissue of opening easily, causes inadequate drainage, and constantly adjustment tip position or repeated puncture increase the patient suffering; The 2nd, in order to penetrate thoracic wall, the thoracic-puncture needle needle point is sharp keen, but passes in the journey along with hydrothorax or pneumatosis are drawn out of at breast, lung constantly again Zhang Yi punctured by sharp keen needle point, cause iatrogenic pneumothorax or hemothorax, cause unnecessary damages to the patient.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes above-mentioned thoracic-puncture needle, provides a kind of risk of can adequate drainage and will puncture lung tissue to reduce to the thoracic-puncture needle of minimum safety.
The technical scheme of this utility model is to adopt double-deck trocar, and its ectomesoderm pin front end is sharp-pointed needle point, and afterbody has " L " shape draw-in groove, forms stop with the embolus of internal layer Aculeata, can indicate and the fixing position of ectonexine pin.Internal layer pin front end is a tack, and its front end leaves side opening.
Outer needle penetration thoracic wall during use, be extracted into hydrothorax or aerothorax after, push away the internal layer pin forward and make it to protrude in outside the sharp needle point of outer pin, through the fixing internal and external pin position of stop.
The advantage of utility model is that the internal layer pin through tack extracts hydrothorax after puncturing successfully, avoids accidentally injuring the risk of lung tissue; The side opening of internal layer pin front end has been avoided being stopped up by floating thing simultaneously, guarantees that drain is unobstructed.

The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described: this thoracic-puncture needle by outer pin 1, internal layer pin 2, side opening 3, embolus 4, " L " shape draw-in groove constitute 5, needle point 6, tack 7 constitute.Internal layer pin 2 front ends are tack 7, and side opening 3 is arranged, and outer pin front end is a needle point 6." L " shape draw-in groove 5 of outer pin 1 afterbody constitutes stop with the embolus of internal layer pin 2 afterbodys 4.
