Description

Thrombus taking device

Technical Field

The utility model relates to a thrombus removes technical field, especially relates to a get and tie device.

Background

Thrombi are small pieces of blood flow that form on the surface of an endovascular denuded or repaired site. In variable flow dependent patterns, the thrombus is composed of insoluble fibrin, deposited platelets, accumulated leukocytes and entrapped erythrocytes.

With the current rise in the standard of living, the incidence of thrombotic disease is increasing, which can block or completely interrupt the flow of blood. If such embolism in a peripheral blood vessel would have serious consequences, if not even disabling, and if it is even fatal, the rapid and effective removal of the blockage is a problem that those skilled in the art need to solve. In the prior art, an aspiration catheter is generally used to remove foreign matters such as thrombus in a blood vessel. The suction catheter is conveyed to the thrombus site, and foreign matters such as thrombus are discharged out of the body along the inner cavity of the catheter by applying negative pressure to the proximal end of the suction catheter, so that blood circulation is reestablished.

But present suction catheter can not effectual arrival expectation pathological change position, complex operation, the risk factor is high and do not have good suction efficiency, present most suction catheter is in order to increase the development nature of distal end, mostly adopts rigid development ring, the mode that this kind of development ring mostly adopts the forging and pressing is fixed at the distal end, development ring after the forging and pressing is many to have the polygon of edges and corners, this can cause two drawbacks, firstly fish tail vascular wall or supporting pipe inner wall in the in-process that advances, secondly the thrombus of being sucked can block in the pipe head end, cause the operation failure.

Most no near-end of current suction catheter blocks up the sacculus, causes blood most to be from the near-end suction, can't guarantee to the suction effect of distal end, leads to by the blood volume increase of taking out, has increased patient's health burden, needs to supply xenogenesis blood at the in-process of operation, and is inefficient, increases the operation time, also can increase the risk of operation: and in thrombus suction in-process, inevitable can cause the thrombus to break or drop, if do not in time handle broken fritter thrombus, very easily cause its blood flow to the more narrow and small blood vessel of distal end along with blood, cause unpredictable risk to the patient, if add the blood of sacculus separation near-end, only can aspirate the blood of blockking up the section distal end during the suction, so this risk can not appear, so the addding of sacculus is very critical, but the product of the sacculus is addd to small part again because the unable back-and-forth movement of suction pipe causes the suction effect to the distal end thrombus poor when the sacculus expansion, cause the suction incomplete.

In the prior art, a guide wire, an intermediate catheter and a guide catheter are required to guide an aspiration catheter to the proximal end of thrombus in the operation process, and the aspiration catheter moves back and forth in a blood vessel along the guide wire in the aspiration process. The cooperation between the catheters of the above procedure requires at least three hemostatic valves, which reduces the actual effective length of the catheter, and is cumbersome and complicated to operate, requiring constant adjustment of the hemostatic valves.

The aspiration catheter is moved adherently within the vessel, and therefore the aspiration port of the aspiration catheter is also off-center from the vessel, which results in aspiration of the thrombus also being off-center, resulting in incomplete aspiration of the thrombus.

When thrombus is sucked in a tortuous blood vessel, the sucked blood flow has a recoil effect on a catheter body, and if the effective support or fixation is lacked, the catheter is easy to swing back and forth during suction, so that the blood vessel is damaged, and even the swing amplitude is too large.

When thrombus is sucked, the thrombus blocks the thrombus suction catheter, and the thrombus suction catheter needs to be taken out of a body and dredged; in the prior art, when the catheter is taken out of the body, the thrombus is very likely to slide out of the thrombus suction catheter again, and irreversible damage is caused to a patient.
