The invention discloses a novel thrombus negative-pressure extraction system by microneedle positioning. The system comprises: a tank body, a microneedle dial plate and a control device are arranged inside the tank body; a microneedle comprises an outer cylinder, the outer cylinder is connected with a needle disc, a guiding shell is arranged at a lower part of the outer cylinder, and is integrallyformed with the outer cylinder, the lower end of the guiding shell has an opening, and the outer cylinder is provided with a liquid outlet; the needle is located inside the outer cylinder, a plurality of receiving grooves are evenly arranged on the side surface of the needle, and the lower ends of the plurality of spring pieces are fixedly connected with the receiving grooves, an adjusting rod isconnected with the needle and extends through a through hole of the dial plate to be connected with the control device for controlling the raising and lowering of the adjusting rod and the needle, and the adjusting rod is provided with a connecting button. a plurality of receiving grooves can be uniformly arranged on the side surface of the needle, the lower end of the spring piece is fixedly connected with the receiving groove, the thrombus entering the guiding shell can be broken to avoid blocking the microneedle, the damage to the skin and blood vessels during operation is greatly reduced,and the operation is safe and the structure is reasonable.
Description
technical field [0001] The present application relates to the technical field of thrombus treatment equipment, in particular to a novel microneedle positioning negative pressure extraction thrombus system. Background technique [0002] The formation of thrombus is mostly due to the following reasons: 1) due to anger injuring the liver, stagnation of qi and blood leads to stasis, stasis leads to blockage of meridians, blockage leads to pain, and slowly forms stagnant thrombus, which enters arteries and major arteries; In severe cases, blood stasis and thrombosis are prone to occur. People with yin deficiency have strong internal heat and usually sweat a lot. Sleeping under the cold wind of the fan or air conditioner will cause sweating, poor blood circulation, rheumatism, and local venous stasis and thrombus; 3) After trauma or pregnancy, excessive bleeding will cause blood backflow in the extremities, resulting in substances in the blood (fibrin, increased blood lipids, pre...
