A built-in medical ultrasonic thrombolysis therapy instrument

Abstract

The invention relates to the technical field of medical apparatuses. The invention discloses a built-in medical ultrasonic thrombolytic therapy apparatus, which comprises an infusion device, an ultrasonic loading module and an ultrasonic indwelling wave-guide tube. A front cover plate and an amplitude-change pole of an ultrasonic transducer in the ultrasonic loading module are made from a TC4 titanium alloy material, and through holes, which are [phi]1mm in diameter, are kept in the middles of the front cover plate and the amplitude-change pole. The ultrasonic indwelling wave-guide tube entersinto a blood vessel from the upstream side of the blood vessel that thrombus occurs along the direction of a blood flow. A plurality of small holes are excavated in two sides of the part, which enters the blood vessel, of the ultrasonic indwelling wave-guide tube, so that ultrasonic wave is directly emitted into the blood vessel having the thrombus, and then under the assistance of thrombolytic agent, the thrombus can be ablated. Based upon experimental verification, the therapy apparatus, on treating thrombotic diseases, is non-invasive, simple and convenient to operate and suitable for reuse. Ultrasonic energy merely plays a local role in vivo, and an ultrasonic action and medicines directly reach focuses, so that a good thrombolysis effect is achieved; and meanwhile, the therapy apparatus has the huge advantages of being low in injury on surrounding tissues, safe and free from side effects and adverse reactions, and the like.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a built-in medical ultrasonic thrombolysis treatment instrument. Background technique [0002] According to reliable statistics, there are about 330 million hypertensive patients in my country, accounting for about 23.6% of the total population, which is more than the entire population of the United States. With the aging population, the proportion will further increase. At the famous Yalta Conference, Roosevelt, Stalin and Churchill restructured the world pattern. However, they all died of cardiovascular and cerebrovascular-induced diseases. High blood pressure means that when the blood vessel narrows and encounters blockage and poor flow, the lateral pressure on the vessel wall is higher than the normal value. High blood pressure will select the heart, brain, kidney, eyes and other organs as targets for damage, which is "target organ damage". In short, wherever there ...

Problems solved by technology

This is a way of combining internal and external, which indeed promotes the ablation of thrombus and improves the effect, but the patient still feels burning discomfort, and does not maximize the performance advantages of ultrasound
