Abstract
The utility model relates to the technical field of medical equipment, specifically a well outage compliance sacculus expansion pipe, the pipe be equipped with eccentric filament guiding channel along the inner chamber axial, be equipped with the sufficient passageway of sacculus along its axial in the pipe wall of this pipe, set up the sacculus on the outer wall of pipe distal end, the cyst wall thickness of this sacculus is by the link gradually attenuation of centre department to both sides, the sufficient passageway of sacculus passes with this sacculus intercommunication behind the pipe wall of pipe. The beneficial effects of the utility model are that, can successfully treat the aorta intermediate layer of serious distortion through the cavity sacculus pipe that has high compliance. In addition, to being about to ruptured arotic disease (like the aortic aneurysm), well outage compliance sacculus pipe can play at once and to seal broken split while and permit blood through the distal end that the cavity passageway arrived the pathological change position, does not influence the blood vessel and supply distal end organ blood, the prevention with reduce the complication.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of hollow highly conforming properties sacculus dilating catheter.
Background technology
Along with raising and the population structure aging of living standards of the people, the incidence rate of vascular system disease, disability rate and fatality rate rise year by year. For dissection of aorta, conventional surgical treatment adopts opens breast or opens the mode of abdomen, with artificial vessel replacement's pathological changes aorta, often needs extracorporeal circulation, and the wound of which is big, it is many to lose blood, and complication rate and mortality rate are all significantly high.
Extensively carrying out of intracavity less invasive techniques brings Gospel for dissection of aorta patient, and Normal practice is, through femoral artery little otch, implant system lining is affixed on aorta inwall, reaches isolation interlayer breach, promotes the purpose of false chamber thrombosis. But endovascular graft can not solve all vascular lesions, serious distortion blood vessel generally only allowing seal wire pass through, implant system is difficult to pass through, and brings difficulty to successive treatment.
Often using sacculus in intracavity minimally-invasive treatment process, be divided into pre-expansion and rear expansion, the former purpose is expansion lesion blood vessel, is beneficial to intracavity implant system and passes through; The latter's purpose is expandable stent, makes implant system better be covered on blood vessel. But only allowing seal wire to pass through for serious distortion pathological changes, conventional balloon, implant system are difficult to pass through, and bring difficulty to next step treatment.
Utility model content
The purpose of this utility model is in that to overcome the deficiencies in the prior art, it is provided that a kind of foley's tube that implant system can effectively be delivered to diseased region.
This utility model one hollow highly conforming properties sacculus dilating catheter, described conduit is axially arranged with eccentric silk guide passage along inner chamber, is axially arranged with the full passage of sacculus along it in the tube wall of this conduit;
Arranging sacculus on the outer wall of described distal end of catheter, the wall thickness of this sacculus is thinning gradually to the junction at two ends by middle;
The full passage of described sacculus connects with this sacculus after the tube wall of described conduit. Sacculus, by, after the diseased region of serious distortion, through eccentric silk guide passage and the far-end of seal wire being imported this hollow highly conforming properties sacculus dilating catheter, is filled by the full passage of sacculus, makes sacculus be fixed in the vascular wall of diseased region far-end by seal wire; Now in the inner chamber of conduit, introduce implant system through another root seal wire, after implant system arrives target position by described hollow highly conforming properties foley's tube, reclaim this hollow highly conforming properties foley's tube and the seal wire in eccentric silk guide passage, and discharge implant system, the dissection of aorta of successful treatment serious distortion.
Preferably, described sacculus is respectively provided on two sides with labelling point at its cyst wall.
Preferably, the external diameter of described conduit is 26��36mm, and internal diameter is 18��28mm;
The external diameter of described eccentric silk guide passage is 2��4mm, and internal diameter is 0.5��1mm.
The beneficial effects of the utility model it is possible to the dissection of aorta of the hollow ball ductus bursae successful treatment serious distortion by having highly conforming properties. Additionally, for being about to the arotic disease (such as aortic aneurysm) broken, described hollow highly conforming properties foley's tube can play while at once closing breach and allow blood to arrive the far-end of diseased region through hollow channel, do not affect blood vessel to remote organ blood confession, prevention and minimizing complication.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
Embodiment 1:
A kind of hollow highly conforming properties sacculus dilating catheter as shown in Figure 1, 2, described conduit 1 is axially arranged with eccentric silk guide passage 2 along inner chamber, is axially arranged with the full passage 3 of sacculus along it in the tube wall of this conduit 1;
Arranging sacculus 4 on the outer wall of described conduit 1 far-end, the wall thickness of this sacculus 4 is thinning gradually to the junction at two ends by middle;
The full passage 3 of described sacculus connects with this sacculus 4 after the tube wall of described conduit 1. Seal wire is by after the diseased region of serious distortion, the far-end of seal wire through eccentric silk guide passage 2 and is imported this hollow highly conforming properties sacculus dilating catheter, by sacculus full passage 3, sacculus 4 is filled, make sacculus 4 be fixed in the vascular wall of diseased region far-end; Now in the inner chamber of conduit 1, introduce implant system through another root seal wire, after implant system arrives target position by described hollow highly conforming properties foley's tube, reclaim this hollow highly conforming properties foley's tube and the seal wire in eccentric silk guide passage 2, and discharge implant system, the dissection of aorta of successful treatment serious distortion. Additionally, for being about to the arotic disease (such as aortic aneurysm) broken, described hollow highly conforming properties foley's tube can play while at once closing breach and allow blood to arrive the far-end of diseased region through hollow channel, do not affect blood vessel to remote organ blood confession, prevention and minimizing complication.
Preferably, described sacculus 4 is respectively provided on two sides with labelling point 5 at its cyst wall.
Preferably, the external diameter of described conduit 1 is 26��36mm, and internal diameter is 18��28mm;
The external diameter of described eccentric silk guide passage 2 is 2��4mm, and internal diameter is 0.5��1mm.
Below the preferred embodiment this utility model created has illustrated, but this utility model is created and is not limited to described embodiment, those of ordinary skill in the art can also make all equivalent modification or replacement under the premise without prejudice to this utility model creative spirit, and these equivalent modifications or replacement are all contained in the application claim limited range.
