An interventional thrombectomy device for cardiovascular embolism

technical field

The invention relates to an interventional thrombus removal device, in particular to an interventional thrombus removal device for cardiovascular embolism.

Background technique

At present, the hospital’s treatment method for patients with cardiovascular embolism is to first use vacuum force to absorb the thrombus or embolus in the patient’s blood vessel, and then use a drill to crush the remaining plaque or embolus, because the medical staff cannot accurately control the vacuum The size of the force, if the vacuum force is too large, it is easy to cause damage to the blood vessels of the patient, and if the vacuum force is too small, the thrombus or embolus in the patient's blood vessels will not be completely absorbed.

At this time, the second electromagnet and the fourth electromagnet absorb the first electromagnet and the third electromagnet respectively. Under the action of the electromagnet, the first slider and the slider move slowly from left to right. Synchronously, the slider drives the first ejector pin, the connecting pin, the second ejector pin and the second slider to move from left to right. The movement finally makes the sharp net move from left to right. Under the action of the sharp net, the thrombus or embolus in the patient's blood vessel is slowly crushed. At the same time, by turning on the second switch, the suction pump starts the suction function. , under the suction of the suction pump, the crushed thrombus or embolus in granular form is discharged into the waste box through the suction pipe. Through the above treatment methods, the thrombus or embolus in the blood vessel of the patient is cleaned up. , when the treatment is completed, the medical staff will first take the device out of the patient's blood vessel, and then move the discarded box to the designated area for cleaning. The method of smashing and then sucking can remove the thrombus or embolus in the patient's blood vessel, which improves the treatment effect of the patient and the work efficiency of the medical staff. At the same time, the positioning pin is to control the maximum value of the sharp tool net. To prevent damage to the patient's blood vessels due to excessive stretching of the sharp tool net, the one-way valve is to prevent the air pressure inflated by the inhalation pump from being discharged from the inhalation tube, which improves the stability of the air pressure inside the fixed rod and the first slide rod.
