Problems solved by technology

[0003] When desilting and removing thrombus in a patient with thrombus, the doctor inserts the dredging piece into the thrombus in the patient's blood vessel and cuts the thrombus through the cutting head of the dredging piece at high speed at 360 degrees. At the same time of thrombus removal, the thrombus fragments after thrombus removal cannot be effectively grasped, so that a small part of blood clots, blood lipid plaques, atherosclerosis and other foreign objects in the thrombus will remain in the patient's blood vessels, increasing The formation of new thrombus leads to re-occlusion of the blood vessel, and in the process of thrombus removal, if there are large thrombus fragments flowing directly into the thrombus extraction pipeline, it will cause blockage of the thrombus extraction pipeline and affect the effect of thrombus drainage

Abstract

The invention discloses a cerebrovascular blood stasis removing and thrombus removing system which structurally comprises an operator, a handle, a guide-in opening, a recycling cavity, a thrombus taking pipe, a dredging pipe, a blocking and filtering device and a puncture head. When the cerebrovascular blood stasis removing and thrombus removing system is used after improvement, thrombus fragments obtained after dredging can be effectively blocked and captured by making contact with the inner wall of a blood vessel in a clearance mode; the captured thrombus fragments can be clamped and broken through an upper inclined guide plate and a lower inclined guide plate, the area of the thrombus fragments can be effectively reduced, the thrombus fragments are prevented from blocking the dredging pipe, then the thrombus fragments are dissolved through a dispersing piece and a medicine dissolving layer, the thrombus fragments in blood are separated and filtered through a separation net, the thrombus fragments are prevented from remaining in blood vessels of a patient, and the thrombus removing effect is improved.

Description

technical field [0001] The invention relates to the field of medical machinery, in particular to a cerebral blood vessel blood stasis clearing and thrombus removal system. Background technique [0002] Due to changes in dietary structure and other reasons, the incidence of thrombosis is on the rise. Thrombus is a blood clot formed by abnormal aggregation of red blood cells, fibrin, platelets and white blood cells in different proportions in blood vessels. Thrombus The formation will cause a high fatality rate and disability rate to the patient. The thrombus fragments after thrombus drainage are captured by the capture element, which effectively plays the role of dredging and thrombus drainage. When performing thrombus drainage, improved place: [0003] When desilting and removing thrombus in a patient with thrombus, the doctor inserts the dredging piece into the thrombus in the patient's blood vessel and cuts the thrombus through the cutting head of the dredging piece at hi...
