Abstract
The utility model relates to a pericardial puncture needle component, which comprises an out sheath, an inner sheath, a puncture needle, and a guide wire with a flexible soft hook in the front end, wherein, the outer diameter of the inner sheath is slightly smaller than the inner diameter of the outer sheath, the diameter of the guide wire is slightly less than the inner diameter of the puncture needle, and the inner diameter of the inner sheath is slightly larger than the diameter of the guide wire. The utility model with reasonable design makes pericardiocentesis easy, and guarantees high successful rate. In general, no damage and complication occurs during the operation process so as to reduce the pain of the patient.
Description
Technical field: this utility model belongs to the medical apparatus technical field, relates to a kind of paracentesis pericardii needle assembly.
Background technology: the paracentesis pericardii pin of prior art, generally all form by inner core and epitheca two parts.This paracentesis pericardii pin, because its inner core is thicker, the tip is more blunt, and therefore puncture is relatively more difficult, and success rate is lower, and often develops complications, even may damage heart.
Summary of the invention: the purpose of this utility model provides a kind of novel paracentesis pericardii needle assembly, in order to overcome the existing above-mentioned defective of prior art puncture needle.The purpose of this utility model is to improve to realize on the basis of prior art puncture needle, it comprises epitheca, its main points are that it also has interior sheath, piercing needle and front end is the guide wire formation of the soft hook of elasticity, wherein, interior sheath external diameter is slightly less than the epitheca internal diameter, the diameter of guide wire is slightly less than the piercing needle internal diameter, and the internal diameter of interior sheath is slightly larger than the diameter of guide wire.During use, carry out paracentesis pericardii with piercing needle earlier, whether the piercing needle tail end is observed on inserting needle limit, limit has hydrops to flow out, and when having treated that hydrops flows out, illustrates that the piercing needle front end has arrived pericardium, stops inserting needle this moment; With the front end cut-off of guide wire, insert again,, withdraw from piercing needle then until pericardium from the piercing needle tail end; Again interior sheath is inserted in epitheca, the front end of the tail end of guide wire from interior sheath is inserted, and under the guide function of guide wire, interior sheath and epitheca are inserted pericardium together, again guide wire and interior sheath are withdrawed from; Above-mentioned said withdraw from piercing needle after, also can be earlier the front end of the tail end of guide wire from interior sheath be inserted, and under the guide function of guide wire, interior sheath is inserted pericardium, carry out a reaming, behind the sheath, again epitheca is inserted pericardium under the guide function of guide wire in withdrawing from; Then latex drainage tube is inserted pericardium from the epitheca inner chamber, again epitheca is withdrawed from, and latex drainage tube is fixed, promptly finish paracentesis pericardii, carry out the drain of pericardial effusion.
This utility model is reasonable in design, and the paracentesis pericardii ratio is easier to, and the success rate height generally can not damage heart and develop complications, and helps alleviating patient's misery.
Description of drawings: accompanying drawing is this utility model assembly sketch map
The specific embodiment: with reference to the accompanying drawings, 4 is epithecas among the figure, the 3rd, interior sheath, the external diameter of interior sheath 3 is slightly less than the internal diameter of epitheca 4, and interior sheath 3 and epitheca 4 can suits, and the diameter of guide wire 2 is slightly less than the internal diameter of piercing needle 1, front end has the soft hook of elasticity, guide wire 2 can penetrate in the piercing needle 1, and the internal diameter of interior sheath 3 is slightly larger than the diameter of guide wire 2, and guide wire 2 also can penetrate in the interior sheath 3.
Claims (1)
