Embodiment

[0042] Example: see figure 1 —7.

[0043] The invention discloses an ultrasonic thrombus removal system, which comprises a front sheath tube 1 and a rear sheath tube 5 which are placed in a blood vessel 2 and are relatively independent. The rear end of the front sheath tube 1 and the front end of the rear sheath tube 5 are There are occlusion balloons in the suit, which are respectively the front occlusion balloon 105 and the rear occlusion balloon 504. The front occlusion balloon 105 and the rear occlusion balloon 504 are respectively located on both sides of the thrombus 3 in the blood vessel and both A broken cavity 4 is formed between them; the front occlusion balloon 105 and the rear occlusion balloon 504 expand or contract in the blood vessel 2 through external force extrusion or relaxation to block or open the thrombus back and forth, and the back sheath 5 A coaxial core tube 502 is provided inside, the front end of the core tube 502 is a breaker 501 for breaking throm...

Abstract

The invention belongs to a medical apparatus used in an interventional surgical method, and particularly relates to an ultrasonic thrombus removal system. The system comprises a front sheath tube and a rear sheath tube which are arranged in a blood vessel and independent from each other, blocking balloons, namely a front blocking balloon and a rear blocking balloon, are installed on the outsides of the rear end of the front sheath tube and the front end of the rear sheath tube in a sleeving mode, the front blocking balloon and the rear blocking balloon are located on both sides of a thrombus in the blood vessel, and a crushing cavity is formed between the front blocking balloon and the rear blocking balloon; the front blocking balloon and the rear blocking balloon expand or contract in the blood vessel by extrusion or relaxation of external force to block or open the front and rear of the thrombus, a core tube extending the rear sheath tube is coaxially arranged in the rear sheath tube, the front end of the core tube is a crusher used for crushing the thrombus, and a discharge tube communicated with the rear sheath tube is arranged at the lower end of the rear sheath tube. According to the structures of the two sheath tubes and the blocking balloons, the thrombus is crushed by means of the crusher, the structure is original, and the thrombus removal effect is good.

Description

technical field [0001] The invention belongs to a medical device used in an interventional operation method, and is a device for crushing, extracting and discharging deposits in a blood vessel. Specifically, it relates to an ultrasonic thrombus removal system. Background technique [0002] Thrombosis often occurs in cerebral arteries and veins of the human body. At present, there are mainly drug-induced thrombolysis, surgical thrombus removal and mechanical thrombus removal for thrombotic diseases. [0003] Drug-induced thrombolysis uses intravenous injection of thrombolytic drugs to directly or indirectly dissolve the thrombus, thereby dredging the blocked blood vessels; another thrombolytic method is to directly introduce the drug into the thrombus through a catheter. This thrombolytic method is prone to bleeding side effects, especially for patients with visceral or cerebral hemorrhage risks, thrombolytic therapy should be contraindicated. [0004] Surgical treatment inv...
