Abstract

The invention provides a suction catheter. The suction catheter comprises a suction component and a balloon component, wherein the suction component is provided with a suction cavity; the balloon component is arranged on the suction component in a sleeving mode; a balloon cavity is defined by the inner wall of the balloon component and the outer wall of the suction component jointly; at least onecirculation groove extending in the extending direction of the suction component is formed in the outer wall of the balloon component; the balloon component has a contraction state when no fluid is introduced into the balloon cavity and an expansion state after the fluid is introduced into the balloon cavity through an injection port; the groove walls of the circulation grooves are distributed inthe circumferential direction of the outer wall of the balloon component at intervals; and the circulation grooves keep through from the far end to the near end when the balloon component is in the expansion state. According to the suction catheter, the circulation grooves are formed in the outer wall of the balloon component, so that when the balloon component is in the expansion state and the outer wall of the balloon component is attached to the wall of blood vessel, blood can continuously flow through the circulation grooves which are through from far to near, blood vessel blockage is prevented, normal blood supply of myocardium is guaranteed, and surgical risks are reduced.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a suction catheter. Background technique [0002] Coronary atherosclerotic heart disease has become the number one killer threatening people's health and life. Unstable coronary atherosclerotic plaque rupture will lead to the formation of acute thrombus, occlusion of the coronary artery lumen, interruption of blood flow, and ischemia or necrosis of myocardial cells in the corresponding blood supply area. The key to treating patients with acute coronary syndrome (ACS) is to quickly open the infarcted blood vessels and restore blood supply to myocardial cells, so as to reduce the size of myocardial infarction, reduce the risk of complications, and prevent possible short-term and long-term sequelae. [0003] At present, a suction catheter is usually used to aspirate the thrombus, that is, the suction catheter is sent to the thrombus site, and then the thrombus is drawn ...
