Silk 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 worn
Pricker 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 to
Seal 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 1
Portion, 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 opposite
Silk 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 wall
Layer, 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 parietale
Shape has certain tension, and lower full of hydrops pressure in cavum pericardiale, enters cavum pericardiale when puncture needle 3 punctures pericardium parietale
Meanwhile under the action of pressure difference, seal wire 5 loses the resistance moved forward, bullet while puncturing pericardium parietale with puncture needle 3
Out), 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 clip
7, 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 extraneous
Hose 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 3
When 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 risen
It to the effect of protection needle point, avoids sharp needle point from puncturing coronary artery and heart, then carry out hydrops extraction, completes operation, be
A 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.
