Folder 123 can rotate predetermined angular around the second connector 121, form good clamping.
Position-limit mechanism 140 is specifically described with reference to the accompanying drawing:
In the present embodiment, position-limit mechanism 140 includes the second lug boss 1421 and outer limit sliding chutes 1422.Such as Figure 10-13
Shown, the second lug boss 1421 is set to the second connector 121.As shown in Figure 15 and Figure 17, outer limit sliding chutes 1422 are set to third
Valve folder 130, outer limit sliding chutes 1422 it is closed at both ends.In conjunction with shown in Fig. 2, Fig. 5, the second lug boss 1421 is slidedly arranged on outer limit and slides
Slot 1422.In the present embodiment, position-limit mechanism 140 includes multiple second lug bosses 1421 and multiple outer limit sliding chutes 1422, more
Circumferentially-spaced distribution of a second lug boss 1421 along the second connector 121, outer limit sliding chutes 1422 and the second lug boss 1421
It corresponds.Multiple second lug bosses 1421 are evenly spaced on preferably along the circumferential direction of the second connector 121.The present embodiment
In, the quantity of the second lug boss 1421 is 2.
The usage mode of heart bicuspid valve folder 100 briefly described below.
Operator punctures from the left chest notch and the apex of the heart of patient first, conduit is then inserted into left ventricle along opening, so
Heart bicuspid valve folder 100 is sent by left ventricle from conduit by conveying device afterwards, is guided by ultrasound and radioactive ray from the left heart
Room enters bicuspid valve.Heart bicuspid valve folder 100 is rounding state in the catheter, as shown in Figs. 1-2.100 are pressed from both sides in heart bicuspid valve
Into after left ventricle, the second valve folder 120 is controlled relative to 130 sliding of third valve folder, until the second left kink by control unit
124, the second right kink 125 is detached from third valve folder 130, and the second left valve folder 122, the second right valve folder 123 open, as shown in Figure 3.
Then, so that the upper surface of the second left valve folder 122, the second right valve folder 123 is bonded the lower surface of left leaflet, right leaflet respectively.So
Afterwards, control unit controls the first valve folder 110 relative to 120 sliding of the second valve folder, until the first left kink 114, the first right bending
Portion 115 is detached from the second connector 121, and the first left valve folder 112, the first right valve folder 113 open；First valve folder 110 and the second valve press from both sides
120 form clamping, as illustrated in figures 4-5.At this point, the first valve folder 110 presss from both sides with the second valve and 120 clamps bicuspid valve, the is then controlled
Three valves press from both sides 130 upward slidings, so that the first valve folder 110 comes back to the first rounding state, the second valve folder 120 comes back to second
Rounding state, clamped left leaflet, right leaflet enter holding tank 132 from the notch 131 of third valve folder 130, then detect two
Whether cusp, which also backflows or backflow, significantly reduces phenomenon to judge whether heart bicuspid valve folder 100 has been clipped in correct position.
If it is determined that heart bicuspid valve folder 100 has been clipped in correct position, so that it may so that heart bicuspid valve folder 100 is detached from conveying
Device, last bicuspid valve are firmly clipped in heart bicuspid valve folder 100.Then conveying device is withdrawn from left ventricle, is sutured
The apex of the heart site of puncture of patient and left chest notch.
