Thrombectomy device and thrombectomy system

A thrombectomy system, comprising a thrombectomy device (100), and a thrombus trapping device (200), the thrombectomy device (100) comprises a thrombectomy net (1), and a pushing tube (2), the pushing tube (2) is connected with the thrombectomy net (1), the thrombus trapping device (200) comprises a sheath tube (19), a trapping tube (20) and a trapping net (21) that can be stored in the sheath tube (19), both the trapping net (21) and the thrombectomy tube (1) have a radial contraction state and a radial expansion state, the trapping net (21) is connected to the trapping tube (20), the pushing tube (2) is configured to push the thrombectomy net (1) into the blood vessel for thrombectomy and to withdraw the thrombectomy net (1) with an embedded thrombus back into the sheath tube (19), and the trapping net (21) is configured to at least partially wrap the thrombectomy net (1) in the process that the thrombectomy net (1) with the embedded thrombus is withdrawn back into the sheath tube (19), after completion of the thrombectomy through the thrombectomy net (1) and before the trapping net (21) wraps at least part of the thrombectomy net (1), the entire thrombectomy net (1) is in a contracted state at least in a stage, and the trapping net (21) is turned over from inside to outside to form an outward flipping state, with an inward flipping guide surface, when the trapping tube (20) and the pushing tube (2) are moved synchronously from the distal end to the proximal end, exposed inside of the trapping net (21) is quickly flipped inward along the inward flipping guide surface to at least partially wrap the thrombectomy net (1), and is withdrawn back into the sheath tube (19) together with the thrombectomy net (1).
