The invention belongs to the field of interventional medical instruments, and relates in particular to a thrombus removal device used for removing a thrombus in a blood vessel. The thrombus removal device includes an elongated delivery member and a plurality of thrombus removal members disposed on the elongated delivery member; the thrombus removal member has a compressed configuration and an expanded configuration formed from the compressed configuration by means of self-expansion; and at least one thrombus removal member among the plurality of thrombus removal members is rotatably connected to the elongated delivery member. By means of causing the thrombus removal member to have rotational degrees of freedom, the thrombus removal device provided by the present invention enables a thrombus to enter the thrombus removal member more easily by means of a thrombus entrance so that the thrombus removal member may fully contact the thrombus, thereby achieving effective capture of the thrombus.
