Adjustable microcatheters for cerebrovascular intervention

Abstract

The invention discloses an adjustable microcatheter for cerebral vascular intervention, which includes a guide wire, a catheter body, an escape hole, an applicator, a soft pad, a ferrule, a splint, a threaded sleeve, a handle, an insulating sleeve, a push plate, and a spring. Conductive block and electromagnet, this adjustable microcatheter for cerebral vascular intervention is simple to operate and powerful. Firstly, the fixed design of the catheter can achieve positioning and fixation of the catheter, ensuring stability and safety during subsequent operations. Secondly, Through the cooperation effect of the clamping guide wire mechanism, the guide wire inside the catheter can also be positioned, which improves the accuracy of treatment operations, reduces the burden of medical staff, and ultimately achieves good clinical promotion and application purposes.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an adjustable microcatheter for cerebrovascular intervention. Background technique [0002] 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 of interventional instruments and materials and modern digital diagnosis and treatment equipment; compared with traditional surgery, it only needs local anesthesia , A small opening of 1-2mm is enough, so it has the advantages of less bleeding, less tra...

AI Technical Summary

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
