Please refer to Fig. 1, Fig. 1 is the foward-push mounting system structural representation for stricture of artery of the present utility model.Described foward-push mounting system is provided with trocar sheath 1 and inner core 2.Described trocar sheath 1 comprises near-end trocar sheath 11 and far-end trocar sheath 12, and described near-end trocar sheath 11 and far-end trocar sheath 12 are to be separated from each other and unconnected.Described inner core 2 is positioned at the inside of trocar sheath 1 hollow, and the near-end of inner core 2 stretches out in the outside of trocar sheath 1, and the far-end of inner core 2 is connected with the far-end of far-end trocar sheath 12, forms cavity between the two, is provided with support 3 in described cavity.The near-end of described support 3 flushes with the near-end of far-end trocar sheath 12, and the edge at described support 3 two ends is provided with support riveting hook 4.The far-end of described near-end trocar sheath 11 is provided with fixation hook 5, and described fixation hook 5 is the hook-shaped support 3 that outwards catches under this utility model foward-push support unused state.Near-end trocar sheath 11 fixing and when pushing away before inner sleeve 2 and far-end trocar sheath 12 fixation hook 5 automatically straighten to linearity, thereby with the central axes releasing bracket near-end of near-end trocar sheath 11.The outer wall of described inner core 2 is provided with block 6, and described block 6 and is positioned at the top of fixation hook 5 between inner core 2 and support 3.Described block 6 is a projection around tube chamber, and lower edge takes the form of inclined plane.The far-end periphery of described near-end trocar sheath 11 is provided with the first mark line 71, and the wall of described inner core 2 is provided with the second mark line 72, and the length of the distance=support 3 of described the first mark line 71 to second mark lines 72.
Please refer to Fig. 2, Fig. 2 is the top view of far-end trocar sheath.But described far-end trocar sheath 12 is to be made by elasticity coiled material such as silica gel, and the edge is provided with the opening 8 with the central axes of far-end trocar sheath 12.Described far-end trocar sheath 12 is non-closed tubular structure under the supporting role of support 3.
Need to prove, described inner core 2 is hollow; The near-end of described inner core 2 stretches out in the outside of trocar sheath 1, can facilitate the patient to operate; Described support riveting hook 4 can fix on support 3 rivetings on blood vessel when releasing bracket 3; The lower end of described fixation hook 5 also can be arranged on the far-end of near-end trocar sheath 11 and be close on the inwall of near-end trocar sheath 11; Described fixation hook 5 is elastic memory tinsels, and when not having masterpiece to be used on fixation hook 5, fixation hook 5 can stretch automatically; Described block 6 is arranged on the top of fixation hook 5, is a ramp projections around tube chamber, and its effect is to stop that fixation hook 5 stretches, and makes it keep case of bending, thereby support 3 rivetings are lived surely; Described block 6 is the projection around tube chamber, and lower edge is designed to inclined plane shape, is in order to guarantee that fixation hook 5 is crooked laterally, fixes support 3 with the mesh that passes support 3; Described the first mark line 71 and the second mark line 72 are that under the employing X ray, but developing material is made, and its effect is for the patient judges whether far-end trocar sheath 12 is pushed into the top of support 3 fully, and namely whether support 3 is discharged fully reference is provided.
Using method and the principle thereof of the foward-push mounting system for stricture of artery of the present utility model are: under X ray, foward-push mounting system of the present utility model is put into the artery stenosis place, the near-end of described near-end trocar sheath 11, inner core 2 and near-end trocar sheath 11 all extends external, by observing the first mark line 71, adjust the length of native system in human body, make the near-end of the near-end alignment artery stenosis of support 3.Then adjust the position of native system in blood vessel, when preparing releasing bracket, push forward inner core 2, described inner core 2 drive far-end trocar sheaths 12 and block 6 are to the blood vessel distal movement, the barrier effect that this moment, fixation hook 5 lost block 6 stretches gradually and (please refer to Fig. 3, Fig. 3 is the foward-push mounting system user mode schematic diagram for stricture of artery of the present utility model), thus the near-end of releasing bracket 3, and the support riveting hook 4 of described support 3 near-ends fixes on support 3 rivetings on blood vessel.Again by observing the position of the first mark line 71 and the second mark line 72, judge whether far-end trocar sheath 12 is pushed to the top of support 3 fully, overlap with the first mark line 71 until the second mark line 72 or position when being in the front end of the first mark line 71, show that support 3 is discharged fully, this moment, described far-end trocar sheath 12 can automatic shrinkage crimping become vortex shape (to please refer to Fig. 4, Fig. 4 is the contraction state schematic diagram of far-end trocar sheath), the inner core 2 of pulling back can be from the internal recovering far-end trocar sheath 12 of support 3 and near-end trocar sheath 11.The near-end trocar sheath 11 of pulling back at last, near-end trocar sheath 11 is recovered.If narrow more serious in blood vessel, consider that support 3 may discharge abundant not, can make it by the method for balloon pre-dilation fully to open.
Foward-push mounting system of the present utility model can accurately make the near-end of support and the proximal anastomosis of artery stenosis, make support cover narrow artery segment fully to expand narrow, avoid mount proximal end to enter higher level's tremulous pulse, prevent that it from disturbing endarterial normal blood flow, to reach good surgical effect.
The above is only preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from this utility model principle; can also make some improvement and replenish, these improvement and replenish and also should be considered as protection domain of the present utility model.
