Repair system and repair method applied in craniocerebral operation

Abstract

The invention discloses a repair system applied in a craniocerebral operation. The system is characterized by comprising movable repair patches, wherein the repair patches are overlaid to form a movable topological structure; the movable topological structure can expand with increased intracranial pressures and can retract with decreased intracranial pressures; and a topological system is composed through arrangement of the multiple repair patches, and the system can expand or retract with intracranial pressure changes. The repair system can be reset after an intracranial pressure of a patient returns to normal after the operation and can finally become consistent with the form of a skeletal flap of the patient removed during the operation. Through application of the repair system, traumas and economic burdens caused to the patient by a second-time operation in a traditional treatment scheme can be avoided; and possible infection and complications such as epilepsy caused by the second-time operation to the patient can be avoided.

Description

technical field [0001] The invention relates to a cranioplasty system for surgical application, in particular to a cranioplasty system which can be expanded or contracted according to the intracranial pressure and can avoid secondary operations in decompressive craniectomy. Background technique [0002] Decompressive craniectomy is an effective neurosurgical treatment for patients with brain herniation to save their lives, but patients often face skull defects during the recovery period after surgery, and a second operation for skull repair is necessary. Cranioplasty can not only protect the fragile brain tissue, but also significantly improve the blood supply of the brain tissue. The cranioplasty can increase the local cerebral blood flow by 15%-30%. Cranioplasty in patients with defects can improve cerebral blood flow on the side of the brain defect and the opposite side, and further improve the quality of life of the patients. [0003] In traditional cranioplasty, the se...

Problems solved by technology

For patients, the second operation itself is a huge mental and physical trauma, and it takes a long time for psychological and physical recovery; secondly, the second operation has a high risk, especially in hard When the separation of the membrane is difficult, it will increase the chance of infection of the patient, and even lead to epilepsy; finally, the second operation also brings a huge economic burden to the patient and his family

[0004] At present, there is no effective plan to avoid the second operation of decompressive craniectomy at home and abroad. Some doctors have tried to grind the removed bone flap through the operating table to thin it and cut it into thin slices and implant it in the missing part of the patient's skull. Because the polished skull often heals poorly after surgery, it may even be absorbed by the body as sequestrum and fail
