Abstract
The utility model relates to a thrombus aspiration catheter comprising a catheter body and a hard head, wherein the head end of the catheter body is provided with a side hole; a protective umbrella is arranged between the hard head and a balloon and composed of a framework and a meshy umbrella cover, the framework of the protective umbrella is composed of a plurality of straight bars with one ends hinged to the hard head, and the meshy umbrella cover is connected to the straight bars; the middle part of each straight bar is hinged with a supporting bar; the other ends of the supporting bars are hinged to a circular ring sleeved on the hard head; the circular ring is connected with a push rod arranged in the catheter body; the near end of the push rod extends out of the catheter body; the unfolding and folding of the protective umbrella are regulated through pushing and pulling the near end of the push rod; the hard head is provided with a limiting device. After the structure is adopted, the protective umbrella can be unfolded through controlling the push rod to block plaque debris generated during aspiration and can be folded after expansion to take out the plaque debris in vitro, so that the plaque debris can be effectively prevented from blocking far end coronary vessels.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of thrombus suction catheter.
Background technology
After acute myocardial infarction, thrombosis stops up coronary artery, utilizes thrombus suction catheter the suction of part thrombosis can be shifted out external, reaches the purpose for the treatment of.But in this process, thrombosis can break, produce little chip, little chip may stop up far-end arteria coronaria blood vessel, causes postoperatively without resurgent, to occur, and causes performing the operation unsuccessful.
The utility model content
The technical problems to be solved in the utility model is to provide the thrombus suction catheter that a kind of chip that prevents that speckle from coming off stops up far-end arteria coronaria blood vessel.
For solving the problems of the technologies described above, thrombus suction catheter of the present utility model, comprise catheter body, and hardhead arranges side opening at the catheter body head end, and a umbrella is set between hardhead and sacculus, and described umbrella is comprised of skeleton and netted umbrella cover.
The skeleton of described umbrella is that many ends are hinged on the straight-bar on hardhead; described netted umbrella cover is connected on straight-bar; every hinged support bar in straight-bar middle part; the other end of support bar is hinged on an annulus; annulus is enclosed within on hardhead; connect a catch bar be arranged in catheter body on annulus, the near-end of catch bar stretches out outside catheter body, adjusts the folding of umbrella by the near-end of push-and-pull catch bar.
On described hardhead, stopping means is set.
After adopting this structure, the chip produced during suction, can open umbrella by controlling catch bar, and umbrella stops the speckle chip, packs up umbrella after expansion, chip taken out of external, can effectively prevent that the chip that speckle comes off from stopping up far-end arteria coronaria blood vessel.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
Fig. 1 is the structural representation of thrombus suction catheter of the present utility model.
Fig. 2 is the enlarged drawing of A part in thrombus suction catheter Fig. 1 of the present utility model.
The specific embodiment
As depicted in figs. 1 and 2, thrombus suction catheter of the present utility model comprises catheter body 1, hardhead 3, at the catheter body head end, side opening 2 is set, a umbrella is set on hardhead 1, umbrella 5 comprises that netted umbrella cover 6 and 8 ends are hinged on the straight-bar 7 on hardhead 3, netted umbrella cover 6 is connected on straight-bar 7, the hinged support bar 8 in straight-bar 7 middle parts, the other end of support bar 8 is hinged on an annulus 9, annulus 9 is enclosed within on hardhead 3, connect a catch bar 10 be arranged in catheter body 1 on annulus 9, the near-end of catch bar 10 stretches out outside catheter body 1, adjust the folding of umbrella 5 by the near-end of push-and-pull catch bar 10, stopping means 11 is set on hardhead 1.
During use, thrombus suction catheter is advanced to the position of thrombosis 13 in blood vessel 12; after aspirate thrombi 13; produce chip, promote catch bar 10, drive annulus 9; make support bar 8 strut straight-bar 7; thereby open umbrella 5, scrap collecting is got up, then pull catch bar 10; the umbrella 5 that closes, extract thrombus suction catheter out.
The above, only to preferred embodiment of the present utility model, not this utility model is done to other forms of restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equal variation.Every this utility model scheme content that do not break away from,, all drop in protection domain of the present utility model any simple modification made for any of the above embodiments, equivalent variations and remodeling according to technical spirit of the present utility model.
