It is in the prior art to take bolt device that protect to takingbolt bracket 100 to be adjusted, and without distal end, thus taking boltIt is not easy to capture thrombus in the process, thrombus is caused to be difficult to take out；And the embolus to fall off during taking bolt be easy to cause secondary boltPlug.In order to solve this problem, present embodiments provide it is a kind of efficiently take bolt take bolt device, what this took bolt device takesbolt bracket 100 to wrapInner support 120 andsupport arm 110 are included, and the two links together in far-end, opposite can be slided between the two in proximal end,So as to adjust the position ofinner support 120, and then change the mutual cooperation relationship ofinner support 120 andsupport arm 110, is conducive toThrombus is firmly captured, and this take bolt device to be provided with distal end protective device can the escape of anti-tampon.
Specifically,inner support 120 is connected as one at distalend fixing end 200 withsupport arm 110, and in proximal end,outer branchFrame 110 is fixedly connected with the first proximalend fixing end 300, andinner support 120 is fixedly connected with the second proximalend fixing end 400, and secondProximalend fixing end 400 is slidably connected with the first proximalend fixing end 300, so that the proximal end of the proximal end ofinner support 120 andsupport arm 110Relative position can change, to adjust the relativeness and mutual cooperation relationship ofinner support 120 andsupport arm 110,And then change the intervening portion relationship of mesh oninner support 120 andsupport arm 110, to achieve the purpose that firmly to capture thrombus.
The use process provided in this embodiment for taking bolt device are as follows: guiding catheter is sent to blood vessel where thrombus, guiding is passed throughConduit send delivery conduit to the distal end of thrombus, then bolt device will be taken to be sent at thrombus by delivery conduit, fixed to live to control seal wireDelivery conduit is withdrawn, takes bolt device to be unfolded under natural resiliency effect at this time, and be bonded with vascular wall, then control lever is pulled to driveSecond proximalend fixing end 400 is mobile, and drives the first proximalend fixing end 300 mobile by the second proximalend fixing end 400, to makeInner support 120 and the relative positional relationship ofsupport arm 110 change, to pass through the mutual ofinner support 120 andsupport arm 110With the use of can firmly capture thrombus, finally the thrombus of bolt device and capture will be taken to take out from blood vessel, to complete to take bolt mistakeJourney.
Provided in this embodiment to take bolt device easy to operate, small volume takes bolt process suitable for all kinds of blood vessels of human body, fromAnd it is no longer influenced by the limitation of volume；Also, this takes bolt device to make byinner support 120 and the relative movement and cooperation ofsupport arm 110With so as to firmly capture thrombus, and the problem of thrombus is escaped has been effectively relieved in distal end protective device, substantially increases bloodThe success rate of bolt capture, is conducive to the thrombus treatment of patient.
It should be noted that as shown in figure 8, under original state, the width of mesh oninner support 120 andsupport arm 110 isIt is identical, and be sine bellows grid, alternatively, the shape of mesh may be other shapes,inner support 120 and outer branchSine bellows grid onframe 110 is interlaced, and ideally the grid ofinner support 120 andsupport arm 110 is mutually divided intoThe a quarter of full size size, thereforeinner support 120 andsupport arm 110 need biggish eyed structure, inlay convenient for thrombusEnter in bracket mesh and is captured；Also, wheninner support 120 is relative to the movement ofsupport arm 110,inner support 120 and outer branchMesh staggered pattern onframe 110 changes, and then be more advantageous in the mesh that thrombus is embedded oninner support 120,Or it in the mesh onsupport arm 110 or ininner support 120 and the interlaced mesh ofsupport arm 110, is more advantageous to bloodThe capture of bolt.It it should be pointed out that the mesh ofinner support 120 and the mesh ofsupport arm 110 are staggered, and is laser engravingOr the grid closed loop configuration of welding, and the area of mesh is 10-80mm2。
In order to realize thatinner support 120 can be mobile relative to supportarm 110, the length dimension ofinner support 120 need to be less than outerThe length dimension ofbracket 110；Specifically, cyclic structure is arranged at the first proximalend fixing end 300 connecting withsupport arm 110310, correspondingly,control lever 500 is set at the second proximalend fixing end 400 connecting withinner support cyclic structure 310, and can be slided incyclic structure 310；Specific operation process are as follows:control lever 500 is pulled,Andinner support 120 is driven to generate movement relative to supportarm 110, during this, the width of mesh oninner support 120 becomesChange, and be used in conjunction with each other with the mesh onsupport arm 110, thrombus is realized jointly and is captured.Therefore, the length ofinner support 120Size need to be less than the length dimension of support arm 110.It should be noted that in the case where original state is fettered without external force, it is interiorBracket 120 can be identical with the cross sectional dimensions ofsupport arm 110, and the cross sectional dimensions for being also possible toinner support 120 comparessupport arm 110 cross sectional dimensions is bigger, and both guarantees of being subject to interlaced can fit closely arrangement, further improves thrombus and catchesThe efficiency obtained, and distal end protective device can anti-tampon escape.
In the optional technical solution of the present embodiment, the proximal end ofsupport arm 110 is provided at least one andcyclic structure 310Converge silk 111 in first proximal end of connection；The proximal end ofinner support 120 is provided with what at least one was connect with 500 end of controlleverConverge silk 121 in the second proximal end；It convergessilk 111 and is correspondingly arranged with the second proximalend convergence silk 121 in the first proximal end.
As shown in fig. 6, the proximal end ofsupport arm 110 andinner support 120 is respectively arranged with the first proximalend convergence silk 111Silk 121 is converged with the second proximal end, and the first proximalend convergence silk 111 is oppositely arranged with the second proximalend convergence silk 121, wherein firstProximalend convergence silk 111 is connect withcyclic structure 310, so thatsupport arm 110 andcyclic structure 310 be linked together；Second is closeEnd convergence silk 121 is connect with the end ofcontrol lever 500, toinner support 120 andcontrol lever 500 be linked together, so justInner support 120 can be driven relative to supportarm 110 by pullingcontrol lever 500 and further convergingsilk 121 by the second proximal endIt is mobile.It should be noted that whensilk 111 is converged in the first proximal end and the second proximalend convergence silk 121 is respectively provided with one, in blood vessel ratioBeing conducive to net in the case where relatively straight and take thrombus, but synchronism is poor, the supportive ofinner support 120 andsupport arm 110 is poor, andThe vascular wall effect that reclines when the turning opening of blood vessel is bad, is unfavorable for turning net and takes thrombus.
As shown in fig. 7, the proximal end ofsupport arm 110 andinner support 120 is respectively arranged with two first proximalend convergence silks 111Silk 121 is converged with the second proximal end, and the angle of the first proximalend convergence silk 111 and the second proximalend convergence silk 121 is 90 degree, is set in this wayIt sets so that the supportive ofinner support 120 andsupport arm 110 is preferable, synchronism is preferable, but when taking bolt, since the first proximal end is convergedSilk 111 and the second proximalend convergence silk 121 are closeer, are unfavorable for pocket and take thrombus, i.e., when thrombus volume is larger, are unfavorable for pocket and enter takingInbolt bracket 100, when thrombus is more loose, then it is easy to hang broken thrombus, be easy to cause the blocking of end tiny blood vessels.
Other than above-mentioned set-up mode, the first proximalend convergence silk 111 is set as one, and the second proximalend convergence silk 121 is setTwo are set to, or on the contrary, so, the balance for being likely to result in bracket is poor, two kinds of proximal end convergence silks are specifically usedSeveral, how to be arranged and be required to be selected by experimental check.
