Detailed description of the invention
The present invention will be further described in detail with detailed description of the invention below in conjunction with the accompanying drawings.
As shown in figs. 1 to 6, a kind of congenital heart disease stopper reclaims pincers, including a control steel wire 10 and be sheathed on control
Moving casing 20 outside steel wire processed, described moving casing 20 end is provided with the flap-type chuck 30 for gripping stopper protuberance,
Described flap-type chuck 30 is made up of folder lobes 310 more than three lobes or three lobes, and described folder lobe 310 lower end outside is articulated with moving casing
20 leading sections, described control steel wire upper end stretch out sleeve pipe 20 front end through multiple be articulated with the connecting rods 110 controlling steel wire 10 upper end with
Folder lobe 310 is connected, and described connecting rod 110 one end is articulated with control steel wire 10 other end and is articulated with folder lobe 310 inwall.
In the present embodiment, described folder lobe 310 top is provided with arc notch 311, and described folder lobe inwall is provided with and rubs for increase
The flank of tooth 312 of wiping power.
During Minimally Invasive Surgery, can realize pressing from both sides the opening and closing of lobe 310 when control steel wire stretches, folder lobe 310 uses more than three lobes
Structure is owing to using Minimally Invasive Surgery image to be only able to display the flat image of two dimensional surface, and in order to ensure the most more
Therefore the realization touching of big probability and gripping use the structure of more than three lobes to design.
Preventing from getting loose in order to the stability of gripping is better achieved, the inside controlling steel wire 10 is additionally provided with a rotatable wire
120, rotatable wire upper end is provided with and leads to after the external screw thread 121 coordinated, gripping to stopper 100 with stopper end female thread
Overwinding turns rotatable wire 120 makes the external screw thread 121 of rotatable wire upper end be fixed on steel wire end with the projection 101 making stopper
Portion.Certainly, female thread can also be provided separately within independent part, and part is fixing with control steel wire upper end to be connected.
In order to grip the stopper under different angles state the most in the blood vessel, both sides, moving casing 20 lower end are articulated with
One fixed sleeving 40, described control steel wire 10 passes in the middle part of moving casing 20 and fixed sleeving 40, bottom described moving casing 20
Side is hinged with a wire drawing 50, and when wire drawing 50 pulls, moving casing 20 rotates around with fixed sleeving 40 pin joint.
Described fixed sleeving 40 end peripheral part is provided with a sliding button 410, and sliding button 410 is fixed in described wire drawing 50
Bottom surface.Control stirring up and down of sliding button 410 during use to realize controlling the flexible of wire drawing 50 thus realize moving casing
The change of 20 angles.
In order to operation is better achieved, being provided with more piece push rod on rear side of described fixed sleeving, described more piece push rod includes first
Panel 610 and the second panel 620, described control steel wire 10 is fixing with the first panel 610 to be connected, and described rotatable wire 120 passes
First panel 610 is fixing with the second panel 620 to be connected, and described first panel 610 is provided with towards fixed sleeving 40 side and can be inserted into
First push rod 611 of fixed sleeving, described second panel 620 is provided with can be inserted in the first push rod towards the first panel side
Two push rods 621.In the present embodiment, described first push rod 611 is provided with and runs through control steel wire and the latch 630 of rotatable wire.
During use, under latch 630 insert state, rotatable wire 120 runs, by first with controlling steel wire 10 simultaneously up and down
Before and after push rod 611, motion realizes the opening and closing of folder lobe 310, after folder lobe 310 grips stopper end, unplugs latch 630 and rotates
Second panel 620 and flexible second push rod 621, can realize the threaded engagement of rotatable wire head end and stopper protuberance.
In order to preferably operate, the first panel both sides and the second panel afterbody are provided with the collar for being inserted in finger.Real
During the application of border, moving casing 20 and fixed sleeving 40 be outside can be enclosed with crust that one layer of biomaterial make to facilitate use.
The foregoing is only presently preferred embodiments of the present invention, all impartial changes done according to scope of the present invention patent with
Modify, all should belong to the covering scope of the present invention.
