Abstract

The invention provides a thrombolysis catheter assembly which relates to the technical field of medical appliances and comprises a catheter, a guide wire, a connecting part, a limiting structure, a length adjustment structure and a seal part, wherein one end of the catheter is connected to the connecting part, and the other end is connected to the limiting structure; the guide wire is located in the catheter, one end is connected to the length adjustment structure, and the other end passes through the limiting structure; the length adjustment structure is located in the catheter and used for adjusting the length of the guide wire inside the catheter; and the seal part is connected to the end, passing through the limiting structure, of the guide wire and is in limited fitting with the limiting structure. According to the thrombolysis catheter assembly, the catheter is connected by the limiting structure and the seal part is limited so as to avoid catheter deformation caused by squeezingof the catheter by the seal part, blocking effects are improved, fitting jam of the catheter and the guide wire is prevented when the length of the guide wire in the catheter is adjusted through length adjustment, and the seal part can be removed easily.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a thrombolysis catheter assembly. Background technique [0002] Peripheral vascular thrombo-occlusive disease is divided into venous thromboembolism and arterial thromboembolism. The current conventional thrombus treatment methods include anticoagulation therapy, surgical treatment and catheter thrombolysis. Among them, the mechanism of catheter-based thrombolysis is to directly perfuse high-concentration thrombolytic drugs around the thrombus through a thrombolytic catheter to dissolve the thrombus and achieve the purpose of treatment. Compared with traditional catheter thrombectomy and other methods, catheter thrombolysis does not require general anesthesia, and the surgical trauma is less, and it can also avoid repeated dragging of the catheter in the blood vessel and reduce damage to the blood vessel, so it is an ideal method. method of thrombosis. [0003] In the ...
