| titleOfInvention | Thrombectomy System |
| abstract | The utility model provides a thrombus retrieval system, comprising: a bracket and a delivery device; wherein, the bracket includes a plurality of sub-stents connected in sequence along the axial direction; the sub-stents have an inner cavity, and the sub-stents have a contracted state and an expanded state, and the expanded state The proximal end and the distal end of the sub-stents are recessed toward the inner cavity of the sub-stents, so that the middle sections of adjacent sub-stents are close to or contact each other, and a recessed space is enclosed. It can be seen that the utility model utilizes the deformation ability of the sub-stent to control the expansion degree of the sub-stent under the pulling of the control wire, avoiding excessive or insufficient radial support force of the stent, and reducing blood vessel damage. After the sub-stent expands, the tension is further increased, and the sub-stent will appear in an expanded state, and then the two middle sections that are close to or in contact can clamp the thrombus and improve the thrombus removal ability of the stent. Moreover, the recessed space formed in the expanded state can accommodate the clamped thrombus, avoiding the problems of the broken thrombus escaping and blocking the blood vessel caused by excessive cutting force and clamping force. |
