Beneficial effects of the present invention: it by the way that seal wire is pressed into arcuation under the action of saddle and puncture needle, is formed certainTension, when puncture needle, which carries seal wire, enters pericardium parietale, under conditions of cavum pericardiale internal and external pressure difference, seal wire is ejected into pericardiumIt is intracavitary, not only play the role of protecting needle point, avoids sharp needle point from puncturing coronary artery and heart, then carry out the pumping of hydropsIt takes, completes operation, be a kind of safe, easy to operate paracentesis pericardii method for being easy to grasp.
Specific embodiment
For the ease of the understanding of those skilled in the art, the present invention is made further below with reference to examples and drawingsBright, the content that embodiment refers to not is limitation of the invention.
A kind of Pericardiocentesis device of the invention referring to FIG. 1 to FIG. 4, including needle propeller 1, saddle 2 and puncture needle 3, it is describedSaddle 2 reciprocatingly slides along 1 length direction of needle propeller, and the puncture needle 3 is detachably connected with needle propeller 1, further includes seal wire 5, leadsSilk braid 6 and clip 7；
The seal wire set 6 is fixedly connected on saddle 2；
The seal wire 5 is arranged in the puncture needle 3 and seal wire set 6；
The clip 7 is connected to seal wire set 6, and the clip 7 is used to control the sliding of seal wire 5；
The seal wire 5 can slide in puncture needle 3 and seal wire set 6.
Specifically, needle propeller 1 is hollow cylinder open at one end in the present embodiment, the syringe part of syringe is selected, is wornPricker 3 is connected to the one end of needle propeller 1 far from opening, and seal wire set 6 is first fixedly connected on saddle 2, saddle 2 is slidably connected toSeal wire 5 is then sequentially passed through puncture needle 3 and seal wire set 6, and the free end of seal wire 5 is made to be retracted the interior of puncture needle 3 by needle propeller 1Portion, the free end of seal wire 5 and the needle point distance of puncture needle 3 are 2-3mm, using the fixed seal wire 5 of clip 7, are led so that seal wire 5 is oppositeSilk braid 6 is fixed, and puncture needle 3 is then punctured into subcutaneous tissue, and pushes saddle 2 mobile towards the direction of puncture needle 3,Seal wire 5 between puncture needle 3 and saddle 2 is in arcuation and keeps mobile tension, continues puncture needle 3 being pierced into pericardial wallLayer, the pop-up of seal wire 5 is (because the seal wire 5 between plant puncture needle 3 and saddle 2 is in bending while puncture needle 3 enters pericardium parietaleShape has certain tension, and lower full of hydrops pressure in cavum pericardiale, enters cavum pericardiale when puncture needle 3 punctures pericardium parietaleMeanwhile under the action of pressure difference, seal wire 5 loses the resistance moved forward, bullet while puncturing pericardium parietale with puncture needle 3Out), that is, play the role of protecting 3 needle point of puncture needle, avoid sharp needle point from puncturing coronary artery and heart, finally unclamp clip7, puncture needle 3 is extracted, leaves seal wire 5, after seal wire 5 enters cavum pericardiale, is expanded after soft tissue again with extraneous expander extraneousHose is placed in cavum pericardiale, extracts hydropericardium by hose, completes operation.
By the way that seal wire 5 is pressed into arcuation under the action of saddle 2 and puncture needle 3, certain tension is formed, when puncture needle 3When carrying seal wire 5 enters pericardium parietale, under conditions of cavum pericardiale internal and external pressure difference, seal wire 5 is ejected into cavum pericardiale, is not only risenIt to the effect of protection needle point, avoids sharp needle point from puncturing coronary artery and heart, then carry out hydrops extraction, completes operation, beA kind of safe, easy to operate paracentesis pericardii method for being easy to grasp.
The Pericardiocentesis device further includes push rod 4, and the push rod 4 pushes saddle 2 to slide on needle propeller 1.
Institute's saddle 2 is equipped with first through hole 21, and the part of the seal wire set 6 is in first through hole 21.
Needle propeller 1 is the syringe part of syringe, and saddle 2 is the piston in syringe, processes one first in saddle 2 and leads toHole 21, a part of seal wire set 6 is in first through hole 21, the central axis of first through hole 21 and the central axis of puncture needle 3It being overlapped, it is ensured that seal wire 5 slides smoothness,
The wall body of the needle propeller 1 is equipped with graduation mark 11, and the setting of graduation mark 11 facilitates observation and controls the shifting of saddle 2Dynamic distance.
The seal wire 5 includes hard end 51 and soft end 52, and the soft end 52 is slidably connected to puncture needle 3, described hardThe sliding of end 51 is connected in seal wire set 6, and before use, hard end 51 first passes through puncture needle 3, hard end 51 sequentially passes through puncture needle3 and seal wire set 6, soft end 52 is retained in puncture needle 3, the setting of soft end 52 and hard end 51 facilitates seal wire 5 successively to wearPuncture needle 3 and seal wire set 6 are crossed, operation is facilitated.
The seal wire 5 is J-type seal wire, and the soft end 52 is pushed out after puncture needle 3 in J-type, and the soft end 52 of seal wire 5 isThe free end of seal wire with flexure mems, soft end 52 includes distal end 521 and proximal end 522, and the distal end 521 is far from hard end51, when soft end 52 is ejected, distal end 521 is in arcuation with proximal end 522, and the direction of distal end 521 towards hard end 51 extends, when wearingIt the soft end 52 of seal wire 5 while being popped up when pricker 3 punctures pericardium parietale, J-type is restored rapidly in this soft end 52 simultaneously, avoidsThe phenomenon that heart is directly pierced in the soft end 52 of seal wire 5 generation.
The puncture needle 3 is Y type puncture needle, and puncture needle 3 has the interface that can connect extraneous syringe 31, can be connect by thisMouth 31 connects extraneous syringes examination suction hydropericardiums, to judge whether puncture needle 3 punctures into cavum pericardiale.
The length of the seal wire set 6 is 6-12mm, it is preferred that the length of seal wire set 6 is 10mm, further ensures that seal wire 5Safety when sliding.
The clip 7 includes ontology 71, the second through-hole 72 and clamping element 73 set on ontology 71, and the clamping element 73 slidesIt is connected to ontology 71, second through-hole 72 is passed through for seal wire 5, and the clamping element 73 is used for clamping seal wire 5, and ontology 71 is connected toSeal wire set 6, the setting of the second through-hole 72 and clamping element 73 facilitate the sliding of control seal wire 5, and structure is simple, at low cost, easily graspMake.
The above is only a preferred embodiment of the present invention, for those of ordinary skill in the art, according to the present inventionThought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as to the present inventionLimitation.
