Blood-vessel embolectomy device with semi-closed structure and thrombus treating apparatus with the same

The invention relates to a blood-vessel embolectomy device with a semi-closed structure and a thrombus treating apparatus with the same. The blood-vessel embolectomy device comprises an embolectomy device body, a developing loop located at the near end of the embolectomy device body and developing rings located at the far end of the embolectomy device body. The embolectomy device body is of a web-tubular or cage-shaped structure composed of a plurality of connected unit grids; the near end of the embolectomy device body is of the closed conical structure; a longitudinal gap is formed in the side face of the far end of the embolectomy device body. The thrombus treating apparatus comprises the blood-vessel embolectomy device with the semi-closed structure, a protecting sheath tube, a conveying wire, a micro guide tube, a guiding guide tube and a rotating bleeding stopping valve. The micro guide tube is pushed to a thrombus embolism in the guiding guide tube along the guiding guide tube, the protecting sheath tube is communicated with the micro guide tube through the rotating bleeding stopping valve, and the embolectomy device body is placed in the protecting sheath tube, pushed into the micro guide tube through the conveying wire and pushed to the thrombus embolism. According to the blood-vessel embolectomy device with the semi-closed structure and the thrombus treating apparatus, flexibility is good, the embolectomy device body can pass through the bent blood vessel or reach the blood vessel with the thin far end, and harm to the blood vessel wall is small.
