The invention discloses a thrombus excision system. An embolus is extracted through a mechanical embolus extraction device, a blood vessel is dredged, and revascularization of the blood vessel is achieved. A saccule guide catheter is put at the near end of the embolus part when the embolus is extracted, blood flow is temporarily blocked, and thus a fine crushed embolus generated in the embolus extraction process is prevented from being flushed to the far end of the blood vessel; meanwhile, for a relatively large embolus, a part of thrombus can also be sucked by virtue of the saccule guide catheter, and then the residual thrombus can be extracted by virtue of a thrombus exsector. The thrombus exsector, the saccule guide catheter and a delivery microcatheter are arranged on the thrombus excision system disclosed by the invention, wherein the thrombus exsector is used as a main component, an excision spring is arranged, and the release state of the excision spring is a conical spiral state. Compared with the prior art, the thrombus excision system has the advantages that the thrombus exsector is very soft, the minimal through size is 0.014' (0.36mm), the thrombus exsector can easily enter a cerebral vessel, a near-end protection technology is adopted in the operation process, and thrombus suction is combined with mechanical embolus extraction, so that the success rate of the operation is improved, and the complications are reduced.

The invention discloses a negative pressure type rapid dredging device for cardiovascular and cerebrovascular embolism, and relates to the technical field of medical instruments. The problem that the thrombus suction operation is not stable is solved. The device specifically comprises a bed body, the outer wall of one side of the bed body is fixedly connected with a working box, the outer wall of the top of the working box is provided with a fixing plate, one end of the fixing plate is provided with a thrombus suction part, the thrombus suction part comprises a suction pipe, a puncture head, a connecting port, a positioning block and a transmission structure, one end of the suction pipe is arranged at one end of the fixing plate, and one end of the suction pipe is slidably connected with a connecting block; one end of the connecting block is slidably connected with a connector. The outer wall of the puncture head is fixedly connected to the circumferential inner wall of the connector; one end of the connector is fixedly connected to the circumferential outer wall of the straw; and one end of the positioning block is rotationally connected to one end of the puncture head. The thrombus dissolving and sucking efficiency is improved, the situation that blood vessels are damaged due to the fact that the stirring speed is too high or the rotating range is large is prevented, and the thrombus sucking safety is guaranteed.

The invention relates to the medicine field, and specifically relates to an application of a Guanxinning composition in the preparation of drugs for treating and / or preventing chronic fatigue syndrome. The Guanxinning composition is composed of red sage root and ligusticum wallichii according to a ratio of 1:1 and has the functions of promoting blood circulation to remove blood stasis, freeing the collateral vessels, and nourishing heart. At present, the Guanxinning composition is made into a Guanxinning injection. The Guanxinning water injection, which is developed in 1970s, has been on sale for more than thirty years, is a common traditional Chinese medicine injection for treating cardio-cerebrovascular diseases in clinic, and can improve the coronary circulation, prevent blood clotting, prominently increase the coronary blood-flow volume, improve myocardial blood supply, prevent and reduce the formation of thrombus, and reduce the range of embolism. The Guanxinning composition is mainly used to treat coronary heart disease and angina.

The invention discloses an evaluation method of a deep vein thrombosis rehabilitation motion. The evaluation method comprises the steps of acquiring each motion state of the rehabilitation motion of ato-be-treated ankle; successively selecting each motion state as a to-be-detected motion state, determining whether the to-be-detected motion state satisfies a first standard rehabilitation action; if yes, determining a next motion state which is adjacent to the to-be-detected motion state satisfies a second standard rehabilitation action; if yes, using the next motion state, which is adjacent tothe to-be-detected motion state, of the to-be-detected motion state as one standard rehabilitation motion, and when a determining finishing instruction is received, evaluating the rehabilitation action of the to-be-treated ankle. The valuation method can realize detection and evaluation to each motion state in the deep vein thrombosis rehabilitation motion and can realize correct ankle rehabilitation motion evaluation of a patient without monitoring by nursing personnel.
