Manual negative pressure suction combined support frame thrombectomy system

Abstract

The invention relates to a manual negative pressure suction combined support frame thrombectomy system, which comprises a guide catheter, a middle catheter, a micro catheter, a micro guide wire, a thrombectomy support frame and a clamp opening injector, wherein the guide catheter, the middle catheter and the micro catheter are sleeved onto the outer side of the thrombectomy support frame; the guide catheter is arranged in the internal carotid of the target artery near end; the micro catheter realizes the super selection to the remote end of the closed blood vessel under the assistance of the micro guide wire and the middle catheter; during the micro guide wire super selection, the shaping is performed to a J shape; the middle catheter and the micro catheter are connected with the top surface of the thrombectomy support frame and is provided with the clamp opening injector. The 60ml clamp opening injector is effectively used for making the negative pressure environment; a suction pump is replaced; the support frame is combined for forming an operation system; the operation is simple; the instant negative pressure is great; the thrombectomy efficiency is effectively improved; the thrombectomy time is shortened. Compared with a suction pump, the thrombectomy system has the advantage of low price and meets the real requirements.

Description

technical field [0001] The invention relates to a manual negative pressure suction combined with a bracket thrombectomy system, in particular to a manual negative pressure suction combined with a bracket thrombectomy system. Background technique [0002] Data show that stroke is the leading cause of death and disability among all neurological diseases worldwide. The period from 1995 to 2013 was the era of intravenous thrombolysis for acute ischemic stroke. With the release of five major studies in 2015, acute ischemic stroke ushered in the era of mechanical thrombectomy for endovascular treatment. Current research focuses on time reduction, patient selection, optimization and evaluation of new imaging modalities, and thrombectomy device selection. Previous studies have found that the time from the onset of the disease to the completion of reperfusion therapy is directly related to the prognosis, and a shorter TOR indicates a better prognosis. Therefore, how to open the occ...

Problems solved by technology

In 2016, some scholars proposed a simple suction thrombectomy technique, using a negative pressure pump to extract the thrombus, but in 2017 the ASTER study evaluated the suction technique and the stent thrombectomy technique, and the suction technique was not better than the stent thrombectomy technique in the successful recanalization rate
