Path system for conveying intracranial pressure control device

By designing a pathway system for delivering intracranial pressure control devices, a minimally invasive approach is used to anchor the guiding and anchoring mechanism at the inferior petrosal sinus, allowing the internal catheter to stably enter the cistern. This solves the problems of long operation time and high risk associated with traditional craniotomy, enabling minimally invasive treatment of hydrocephalus and reducing the risk of complications and infection.

Abstract

The invention belongs to the technical field of hydrocephalus surgery, and particularly relates to an access system for conveying an intracranial pressure control device. In the access system, a guide anchoring mechanism is conveyed to the subrock sinus position through a guide pipe and a micro catheter, so that the far end of the guide anchoring mechanism is anchored to the subrock sinus position; and then the outer guide pipe reaches the subrock sinus position along the guide anchoring mechanism, and it is guaranteed that the access system can stably penetrate through the trunk to reach the subrock sinus position. Then the handle sliding block is moved backwards to drive the outer catheter to move backwards, the puncture needle at the far end of the inner catheter is exposed outwards, then the inner catheter is controlled to move forwards, the puncture needle at the far end of the inner catheter pierces the dura mater to enter the brain pool, and then the intracranial pressure control device can be conveyed into the brain pool through the inner catheter; the passage system is more stable in conveying process, can reduce various complication risks in the operation process, and is beneficial to improving the success rate of the operation.
