Problems solved by technology

[0002] The rational elimination of thrombus has always been a hot topic in the medical field. The use of drugs to eliminate thrombus may cause coagulation disorders or other side effects. The removal of thrombus through interventional vascular surgery involves many technical and equipment problems, and the operation is more complicated. Find a convenient, fast and effective thrombus removal method and related equipment, especially for thrombus formed in artificial lumen, such as thrombus removal in hemodialysis catheter and forearm artificial vascular graft

Embodiment Construction

[0022] Below in conjunction with accompanying drawing and embodiment the present invention is further described: as figure 1 , 2 The in-pipe longitudinal wave embolism suppressor shown in is provided with a base 12, a push motor 9 and a syringe 13.

[0023] The base 12 is used as a receiving seat for the syringe 13 and the push motor 9, and also plays a role in guiding and fixing the injection of the syringe, so as to realize the independent automatic operation of the device.

[0024] The base 12 is provided with a linear guide groove 11, and the linear guide groove 11 is embedded with the bottom of the syringe seat 10 which can move along the linear guide groove. linear motion. The syringe base 10 is provided with a syringe groove parallel to the linear guide groove 11, and the syringe 2 part of the syringe 13 is embedded in the syringe groove. The syringe groove can be a through hole, which is used to limit the degree of freedom of the syringe so that the syringe can only...

Abstract

A longitudinal wave thrombus suppressor in a tube is provided with a base, a pushing motor and a syringe. A linear guide groove is arranged in that base, a syringe cylinder seat is embedded in the linear guide groove, and the syringe can be slidably or fixedly embed in the syringe cylinder seat. A transducer seat movable along a linear guide groove or working in a fixed state is arranged at the rear of the syringe seat, a transducer is arranged in the transducer seat, and a push rod is arranged at the side opposite to the transducer seat and the locking buckle, and the push rod is used as a secondary mover of the pushing motor or driven by the secondary mover of the pushing motor. The invention can realize timely longitudinal wave thrombolysis to the thrombus in the catheter by connectingthe catheter with the external longitudinal wave generator, and can timely eliminate the thrombus formed by the patient.

Description

technical field [0001] The invention relates to medical equipment, in particular to an in-tube longitudinal wave embolism remover. Background technique [0002] The rational elimination of thrombus has always been a hot topic in the medical field. The use of drugs to eliminate thrombus may cause coagulation disorders or other side effects. The removal of thrombus through interventional vascular surgery involves many technical and equipment problems, and the operation is more complicated. Looking for a convenient, fast and effective thrombus elimination method and related equipment, especially for thrombus formed in artificial lumen, such as thrombus elimination in hemodialysis catheter and forearm artificial vascular graft. For this kind of pipeline occlusion and stenosis caused by thrombus formation, how to effectively make thrombolytic drugs continuously contact the surface of thrombus and reduce the concentration of local thrombolytic products is the key to the success of...
