The invention discloses a
thrombus excision
system. An
embolus is extracted through a mechanical
embolus extraction device, a
blood vessel is dredged, and
revascularization of the
blood vessel is achieved. A
saccule guide catheter is put at the near end of the
embolus part when the embolus is extracted,
blood flow is temporarily blocked, and thus a fine crushed embolus generated in the embolus extraction process is prevented from being flushed to the far end of the
blood vessel; meanwhile, for a relatively large embolus, a part of
thrombus can also be sucked by virtue of the
saccule guide catheter, and then the residual
thrombus can be extracted by virtue of a thrombus exsector. The thrombus exsector, the
saccule guide catheter and a delivery microcatheter are arranged on the thrombus excision
system disclosed by the invention, wherein the thrombus exsector is used as a main component, an excision spring is arranged, and the release state of the excision spring is a conical spiral state. Compared with the prior art, the thrombus excision
system has the advantages that the thrombus exsector is very soft, the minimal through size is 0.014' (0.36mm), the thrombus exsector can easily enter a
cerebral vessel, a near-end protection technology is adopted in the operation process, and thrombus suction is combined with mechanical embolus extraction, so that the success rate of the operation is improved, and the complications are reduced.
