Abstract

The invention discloses an artificial cerebral dura mater for tightly mending intraoperative dural injury; the inner surface of the artificial cerebral dura mater is in contact with cerebral tissues, is smooth and is not in adhesion with arachnoid and cerebral tissues; the outer surface of the artificial cerebral dura mater is provided with a plurality of loops (1) for surgical sewing. It is very convenient to perform sewing during surgery, sewing is easy, post-sewing watertightness is good, the artificial cerebral dura mater is simple to operate and is smooth after being fixed, and the watertightness problem of existing artificial cerebral dura mater in use is solved.

Description

technical field [0001] The invention relates to the technical field of medical operations; in particular, it relates to an artificial dura mater used in neurosurgery or brain surgery repair operations. Background technique [0002] In many operations, dural defects are prone to occur or cannot be repaired tightly, and "cerebrospinal fluid leakage" will occur, and even "intracranial infection" will occur, with very serious consequences. Therefore, surgery on the brain and spinal cord requires that the dura mater must be tightly sutured to restore its watertight performance. [0003] Artificial Dura Mater (Artificial Dura Mater) is an artificial substitute material with good histocompatibility for repairing autologous dura mater defects and restoring its watertightness. "Artificial dura mater" is a substitute for human meninges made of artificial materials or biological materials. It is used to repair dura mater or spinal cord defects caused by craniocerebral or spinal cord i...
