This invention relates to the field of traditional Chinese medicine (TCM) technology, and discloses a TCM composition, preparation method, and oral formulation for treating cardiovascular and cerebrovascular diseases of the Qi deficiency and blood stasis type. The TCM composition is made from kudzu root, astragalus root, notoginseng, safflower, chuanxiong rhizome, hawthorn, angelica root, polygonum cuspidatum, licorice root, and salvia miltiorrhiza in specific weight parts. A preferred ratio is 60 parts kudzu root, 60 parts astragalus root, 25 parts notoginseng, 30 parts safflower, 25 parts chuanxiong rhizome, 30 parts hawthorn, 25 parts angelica root, 25 parts polygonum cuspidatum, 10 parts licorice root, and 26 parts salvia miltiorrhiza. It can be used for coronary heart disease, cerebral arteriosclerosis, cerebral thrombosis, hyperlipidemia, or sequelae of cerebral infarction. In preparation, the medicinal materials are cleaned, dried, mixed, and pulverized into a fine powder, passed through a 120-180 mesh sieve, and then formed into water pills using water as a binder. After drying and packaging, the product is obtained. This invention has a scientific formulation and precise proportions, making it suitable for the long-term prevention and treatment of cardiovascular and cerebrovascular diseases of the Qi deficiency and blood stasis type.

This invention discloses a cerebral thrombosis removal device, comprising an outer cannula, a first catheter, a thrombus fragmentation structure, and an artificial blood vessel. The proximal and distal ends of the outer cannula respectively form a first inlet and a first outlet communicating with a first channel. The first catheter is disposed within the first channel. The thrombus fragmentation structure includes a second catheter and a fragmentation section located distal to the second catheter. The second catheter is movably disposed within the first catheter and can extend from the first outlet to fragment the thrombus at the target lesion site. An aspiration channel is formed inside the second catheter, with its distal opening located near the fragmentation section for aspirating the fragmented thrombus fragments. The artificial blood vessel includes a third catheter, the distal end of which is used to cross the thrombus at the target lesion site to reach a distal blood vessel and deliver blood to temporarily relieve ischemia. This invention's cerebral thrombosis removal device can extend the safe surgical time window.
