Abstract

The invention discloses a cerebrovascular intervention puncture positioning device for neurointervention. The cerebrovascular intervention puncture positioning device comprises a bottom plate; an arc-shaped pillow is fixedly connected to the upper end of the bottom plate; two adjusting through holes are formed in the bottom plate in an up-down penetrating mode, and adjusting blocks are slidably connected into the two adjusting through holes; an adjusting mechanism used for adjusting the two adjusting blocks is arranged in the bottom plate; first threaded rods are arranged on the two adjusting blocks in an up-down sliding and penetrating mode; a lifting mechanism used for lifting the two first threaded rods is arranged between the two adjusting blocks; the upper ends of the two first threaded rods are fixedly connected through two arc-shaped plates; the two arc-shaped plates are sleeved with a positioning plate in a sliding mode; a moving mechanism used for moving the positioning plate is arranged outside one of the first threaded rods; and a mounting hole is formed in the lower end of the positioning plate, and the front end of the mounting hole is transparent. According to the device, the position of a puncture needle can be accurately positioned, and the risk of puncture is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a cerebrovascular intervention puncture positioning device for nerve intervention. Background technique [0002] Interventional technology, internal medicine technology, and surgical technology are collectively called the three major medical technologies; compared with the latter two, it is a young technology, which is independent of internal and surgical technology, and coexists with them and develops collaboratively. Interventional technology is divided into three categories: cardiac intervention, peripheral intervention and neurological intervention according to the different professional fields involved; neurological interventional technology, as the name implies, treats nervous system diseases, and it is supported by the digital subtraction angiography (DSA) system. Next, using intravascular catheter operation technology, through specific methods such as selective an...
