Adjusting micro guiding pipe for cerebrovascular intervention

Abstract

The invention discloses an adjusting micro guiding pipe for cerebrovascular intervention. Micro guiding pipe comprises a guiding wire, a guiding pipe body, an avoiding hole, an application soft cushion, a clamping sleeve, a clamping plate, a threaded sleeve, a handle, an insulation sleeve, a push plate, a spring, an electric guiding block and an electromagnetic block. The micro guiding pipe has the advantages of simple operation and powerful function, the positioning and fixing of the guiding pipe can be firstly achieved through a guiding pipe fixing type design, the stability and safety in subsequent operation process is ensured, the positioning of a guiding wire in the guiding pipe can be achieved to improve the accuracy of treatment operation and reduce the operation burden of a medicalworker, and the purpose of excellent clinical popularization is finally achieved.

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 t...

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
