A microcatheter treatment device for intravenous closure

Abstract

The application relates to a closed microcatheter treatment device in the venous cavity, including a control assembly and a catheter assembly; a power source and a male joint connected to the power source are installed in the control assembly; A matching female connector, a guide wire connected to the female connector, and a tube body sleeved outside the guide wire and fixedly connected to the catheter assembly; the guide wire includes a fixed end and a working end, and the fixed end of the guide wire is connected to the female connector; The control assembly is provided with a limiting structure, and the catheter assembly is provided with a limiting member; when the female connector is engaged with the male connector, the catheter assembly is moved away from the working end of the guide wire until the limiting member can rotate radially and snap into the limit. Position structure, so that the working end of the guide wire extends out of the tube body to a stable working state; after releasing the engagement of the limiter and the limit structure, move the catheter assembly so that the working end of the guide wire is retracted into the tube body and switched to non-working state. The application improves the therapeutic effect and shortens the postoperative recovery time of patients.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to a treatment device for closing a microcatheter in the vein cavity. Background technique [0002] Varicose veins, commonly known as "fried tendon legs", is the most common disease in the venous system. The main reason for its formation is that the congenital vascular wall membrane is relatively weak or the same posture is rarely changed for a long time, so that blood accumulates in the lower limbs, and the venous pressure is too high. Symptoms caused by blood vessels protruding from the surface of the skin. Varicose veins mostly occur in the lower extremities. If not treated in time, the thrombus may spread upward or through the communicating veins to the deep veins, causing deep vein thrombosis, which may be life-threatening. [0003] At present, the methods for treating varicose veins mainly include wearing elastic stockings and surgical stripping, among which, the ther...

Problems solved by technology

Varicose veins mostly occur in the lower extremities. If not treated in time, the thrombus may spread upward or through the communicating veins to the deep veins, causing deep vein thrombosis, which may be life-threatening

[0003] At present, the methods for treating varicose veins mainly include wearing elastic stockings and surgical stripping, among which, the therapeutic effect of wearing elastic stockings is not significant; although the treatment method of surgical stripping has a high success rate, it is necessary to remove the veins during the treatment process. Removal of the main trunk will leave a more obvious incision scar after surgery, which is more traumatic, painful, and takes a long time to recover, which brings great inconvenience to the patient

[0004] In view of the related technologies mentioned above, the inventor believes that the traditional treatment method has the defects of poor treatment effect and long recovery time.
