The sidewall of described sliding sleeve is provided with chute, the location matches of the position of chute and described syringe connector.
Described sliding sleeve rear sidewall is provided with penetrating breach, described slide mass is provided with positioning groove, the four-in-one Silk-guiding lead-in device that this afterbody enters silk also includes a U-shaped card, when the gap position on positioning groove and sliding sleeve on slide mass is at once, U-shaped card snaps in positioning groove and breach.
Described syringe connector is provided with the arc push pedal of the depression of mating with thumb.
The inside that described seal wire is introduced mouth body is provided with check valve.
Between described piercing needle and convergent divergent channel inwall, be provided with hermetically-sealed construction.
Beneficial effect of the present invention
The afterbody of this invention enters the four-in-one Silk-guiding lead-in device of silk, and four operating process that simultaneously import in conjunction with puncture, expansion, blood back, seal wire can complete aforesaid operations on an apparatus, improve the efficiency that seal wire imports.
Seal wire is introduced to mouth body in this invention and syringe connector all links together with slide mass, be synchronized with the movement with slide mass, so can realize the length of piercing needle being stretched out to convergent divergent channel, thereby can adapt to different patient's conditions, the length of adjusting flexibly puncture needle and stretching out convergent divergent channel.
Resistance while penetrating in order further to reduce seal wire, piercing needle of the present invention and wire leading pipe are coaxially arranged, and resistance when seal wire imports has been reduced to minimum level, easy to operate, can significantly reduce the time of operation.
At sliding sleeve rear portion, breach is set and positioning groove is set on slide mass, can be in the time that puncture needle be retracted, realize fixing between slide mass and sliding sleeve, like this in the time of expansion, can avoid puncture needle to leap up out, puncture blood vessel, or cause other injuries to patient.
