The invention relates to a thrombus taking device which is used for removing thrombi along a guide wire. The thrombus taking device comprises a thrombus sucking component and a thrombus taking component, the thrombus sucking component comprises an outer pipe, a transmission pipe, a driving part and a thrombus sucking head, the outer pipe is arranged outside the transmission pipe in a sleeving manner, one end of the outer pipe is connected with the thrombus sucking head, the thrombus sucking head is used for inhaling and crushing the thrombi, a thrombus crushing knife is arranged in the thrombus sucking head, two ends of the transmission pipe are connected with the thrombus crushing knife and the driving part, the thrombus taking component is used for dragging the thrombi to the thrombus sucking head and comprises a balloon and a multi-cavity pipe connected with the balloon, the balloon can be contracted or filled with liquid to be expanded, a liquid filling cavity and a wire guide cavity are formed in the multi-cavity pipe, the balloon is filled with the liquid through the liquid filling cavity, a guide wire is arranged in a penetrating manner through the wire guide cavity, and themulti-cavity pipe sequentially penetrates the transmission pipe and the thrombus sucking head, so that the thrombus taking component and the thrombus sucking component axially and relatively move. According to the thrombus taking device, thrombi in the area of a blood vessel with small diameter can be removed, and the thrombi adhered on the wall of the blood vessel can be completely removed.
