Problems solved by technology

Among them, after the microcatheter goes deep into the designated position, in order to improve the stability and accuracy of the treatment, the firmness and stability of the microcatheter are very important. However, the existing microcatheters lack good fixation due to their simple structure and single function. It not only increases the risk of surgery, but also increases the operating burden of medical staff. In view of the above defects, it is necessary to design an adjustable microcatheter for cerebrovascular intervention

Abstract

The invention discloses an adjustable microcatheter for cerebrovascular intervention and a use method thereof. The adjustable microcatheter comprises a guide wire, and further comprises a catheter body, an avoidance hole, a patch, a soft cushion, a clamping sleeve, clamping plates, a threaded sleeve, a handle, an insulating sleeve, a push plate, a spring, a conductive block and an electromagnet. The adjustable microcatheter for cerebrovascular intervention is easy to operate and powerful in function. Firstly, the catheter can be positioned and fixed through the catheter fixing type design, andthe stability and safety in a subsequent operation process are ensured; and secondly, the guide wire in the catheter can be positioned through the cooperation effect of a clamping type guide wire mechanism, the accuracy of treatment operation is improved, the operation burden of medical staff is relieved, and the purpose of satisfactory clinical application and popularization is finally achieved.

Description

[0001] This application is a divisional application of the invention patent application with the application number: 2018111673268 and the title: "Adjustable microcatheter for cerebrovascular intervention". The original filing date is: October 8, 2018. technical field [0002] The invention relates to the technical field of medical devices, in particular to an adjustable microcatheter for cerebrovascular intervention. Background technique [0003] Cerebral hemorrhage refers to non-traumatic intracerebral hemorrhage caused by cerebral hemorrhage, which is mainly related to cerebrovascular lesions, that is, hyperlipidemia, diabetes, hypertension, and aging of blood vessels. The traditional treatment after cerebral hemorrhage is to use drugs, but the drugs are slow to stop bleeding. After coagulation occurs, craniotomy often leaves sequelae. Interventional therapy (arterial microguide wire dilation and stent implantation) is a diagnostic and therapeutic operation using a series...
