Abstract

The invention relates to the technical field of medical instruments, and discloses an injection support and an injection thrombolysis system including the same. The injection support comprises a drugdelivery pipe, a support body capable of elastically expanding in radial direction and a thrombus filter screen, wherein the support body is fixedly arranged on the drug delivery pipe; the support body comprises a plurality of elastic pipes which form the support structure; the elastic pipes are communicated with the drug delivery pipe; and a plurality of drug injection holes are formed in the elastic pipes; and the thrombus filter screen is fixedly arranged on the drug delivery pipe and is positioned at the far end of the support body. According to the embodiment, the injection support capable of elastically expanding is released at the position of thrombus, so that the injection support can inject a thrombolytic agent after being embedded into the thrombus, the thrombolytic agent can directly and accurately act on the thrombus in a large area, the thrombolytic efficiency can be improved, and the thrombolytic agent and the treatment time can be saved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a drug injection stent and a drug injection thrombolysis system comprising it. Background technique [0002] Pulmonary embolism is a common cardiovascular system disease, often caused by deep vein thrombosis in the lower extremities, and has a high mortality rate, seriously endangering the health and quality of life of patients. The existing treatment methods for pulmonary embolism mainly include: drug anticoagulant therapy, systemic thrombolytic therapy, interventional local perfusion thrombolytic therapy, and traditional surgical treatment for pulmonary embolism. With the development of endovascular interventional therapy, interventional therapy for pulmonary embolism has become an effective and important treatment. However, the traditional catheter thrombolysis method needs to place the thrombolysis catheter in the body for a long time, and requires the use of large d...
