Abstract
The utility model relates to a balloon catheter for dilatation for interventional treatment of heart. The balloon catheter comprises a catheter body and a dilatable balloon extending to the remote end, wherein a hard head is arranged at the head part of the catheter body, a protection umbrella is arranged between the hard head and the balloon, and the protection umbrella comprises a framework and a reticular umbrella face; the framework of the protection umbrella comprises a plurality of straight rods, one end of each straight rod is articulated on the hard head, the reticular umbrella face is connected on the straight rods, the middle part of each straight rod is articulated with a support rod, the other end of each support rod is articulated on a circular ring, the circular ring is sheathed on the hard head, a push rod arranged in the catheter body is connected on the circular ring, the near end of the push rod extends out of the catheter body, and the folding and the unfolding of the protection umbrella are adjusted by pushing the near end of the push rod. After the structure is adopted, the balloon is inflated, then plaques fall off, the protection umbrella is unfolded by controlling the push rod, the protection umbrella can block scrap of the plaques, and the protection umbrella is folded after dilatation for taking the scrap out of a human body, so that the scrap of the plaques which fall off can be effectively prevented from blocking distal coronary arteries.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of heart intervention treating expansion foley's tube.
Background technology
Foley's tube is a kind of instrument for the blood vessel Transluminal Angioplasty, has been widely used in the clinical medicine of percutaneous transluminal angio plasty and percutaneous transluminal coronary angioplasty.It is under the guiding of medical imaging device, with Percutaneous Techniques, foley's tube is inserted to the narrow positions of blood vessel, carry out the balloon expandable expansion under proper intensive care, the narrow positions of blood vessel is expanded, thereby reach the purpose of recovering lumen diameter, accelerating blood circulation.During heart intervention treating (PCI), often cause in the balloon expandable process that the chip that speckle comes off stops up far-end arteria coronaria blood vessel, occur without resurgent after causing PCI, cause operative failure.
The utility model content
The technical problems to be solved in the utility model is to provide the foley's tube 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; heart intervention treating expansion foley's tube of the present utility model; comprise catheter body and an expandable balloon that extends to far-end; the head of catheter body is provided with a hardhead; 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, sacculus struts speckle and comes off, and by controlling catch bar, opens umbrella, and umbrella can stop the speckle chip, packs up umbrella after expansion, chip is 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 heart intervention treating expansion of the present utility model with foley's tube.
Fig. 2 is the enlarged drawing of heart intervention treating expansion of the present utility model by A part in foley's tube Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, heart intervention treating expansion foley's tube of the present utility model, comprise catheter body 1 and an expandable balloon 2 that extends to far-end, the head of catheter body 1 is provided with a hardhead 3, a umbrella 5 is set between hardhead 3 and sacculus 2, umbrella 5 comprises netted umbrella cover 6, article 8, an end is 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, foley's tube is advanced to the position of blood vessel 12 specklees 13; after dilating sacculus 2; the speckle generation chip that comes off, promote catch bar 10, drives 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 foley's tube 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.
Claims (3)
1. a heart intervention treating is expanded and is used foley's tube; comprise catheter body and an expandable balloon that extends to far-end; the head of catheter body is provided with a hardhead, it is characterized in that: a umbrella is set between hardhead and sacculus, and described umbrella is comprised of skeleton and netted umbrella cover.
2. according to heart intervention treating expansion foley's tube claimed in claim 1; it is characterized in that: 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.
