The invention belongs to the technical field of medical instruments, and particularly relates to a vibration actuator for cerebral thrombosis removal and thrombus removal equipment, the vibration actuator for cerebral thrombosis removal comprises an actuator body, and the actuator body comprises a guide wire and a tail end actuator connected with the tail end of the guide wire; a vibration device is arranged on the guide wire and used for generating vibration in the length direction of the guide wire. A vibration mode conversion structure is arranged on the end effector and used for converting vibration in the length direction of the guide wire into vibration perpendicular to the length direction of the guide wire. The vibration mode conversion structure is arranged on the end effector, vibration in the length direction of the guide wire is converted into vibration in the direction perpendicular to the length direction of the guide wire, a mechanical effect, a microbeam effect, a cavitation effect and a heat effect are generated at the contact position of the tail end of the effector and the thrombus, and therefore the thrombus is effectively broken, and thrombus dissolution is accelerated.
Description
technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a vibration actuator and thrombus removal equipment for removing cerebral thrombus. Background technique [0002] With the rapid development of population aging, stroke has become one of the leading causes of death in my country, most of which are ischemic strokes. Ischemic stroke is due to the formation of blood clots in blood vessels, resulting in reduced or interrupted blood supply to the brain, causing damage to brain tissue, leading to language barriers, limb movement disorders, and even life-threatening. [0003] For traditional drug thrombolytic therapy, due to the short time window (3-4.5 hours), fewer patients benefit from treatment. Mechanical thrombectomy devices are favored due to their long time window (24 hours) and high rate of recanalization. At present, the expandable stent-type thrombectomy device is widely used. The purpose of thrombus r...
