Abstract

The invention discloses a negative pressure type rapid dredging device for cardiovascular and cerebrovascular embolism, and relates to the technical field of medical instruments. The problem that the thrombus suction operation is not stable is solved. The device specifically comprises a bed body, the outer wall of one side of the bed body is fixedly connected with a working box, the outer wall of the top of the working box is provided with a fixing plate, one end of the fixing plate is provided with a thrombus suction part, the thrombus suction part comprises a suction pipe, a puncture head, a connecting port, a positioning block and a transmission structure, one end of the suction pipe is arranged at one end of the fixing plate, and one end of the suction pipe is slidably connected with a connecting block; one end of the connecting block is slidably connected with a connector. The outer wall of the puncture head is fixedly connected to the circumferential inner wall of the connector; one end of the connector is fixedly connected to the circumferential outer wall of the straw; and one end of the positioning block is rotationally connected to one end of the puncture head. The thrombus dissolving and sucking efficiency is improved, the situation that blood vessels are damaged due to the fact that the stirring speed is too high or the rotating range is large is prevented, and the thrombus sucking safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a negative pressure rapid dredger for cardiovascular and cerebrovascular embolism. Background technique [0002] With the development of society and economy, profound changes have taken place in the way of life of the people, especially the aging of the population and the acceleration of urbanization. The risk factors of cardiovascular and cerebrovascular infarction caused by the "three highs" in China are on the rise. It has led to a continuous increase in the number of patients with cardiovascular and cerebrovascular infarction diseases, and the mortality rates of acute myocardial infarction and cerebral infarction are also on the rise. At present, minimally invasive surgery is the main method for embolism treatment, but the basic working principle of the existing dredger is the catheter extraction method, which gradually sucks out the thrombus under constant changes be...
