Protective exoskeleton plaster for cranial bone absence

Abstract

The invention provides a protective exoskeleton plaster for cranial bone absence. The protective exoskeleton plaster comprises an exoskeleton plaster body and an annular double-sided adhesive, whereinthe exoskeleton plaster body is composed of an external surface layer, an exoskeleton plate and a wrapping layer, and an air vent valve is mounted on the exoskeleton plaster body. According to the protective exoskeleton plaster for cranial bone absence, an exoskeleton support can be equipped outside a scalp of a cranial bone absence part, injury to intracranial tissue caused by an external forcecan be withstood, a normal and stable intracranial pressure can be maintained, a normal form of a cranial cavity can be restored, a normal anatomical position of the intracranial tissue is restored, agood protecting and supporting action is exerted, collapse of the intracranial tissue and a ventricular system is avoided, improvement on brain tissue blood supplying and lowering of incidence rate of complications such as intracranial hemorrhage, epilepsy and hydrocephaly are facilitated, favorable conditions are created for a subsequent cranioplasty, and thus, a patient can gain better prognosis.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a protective exoskeleton sticker for skull loss. Background technique [0002] Craniotomy is a common surgical procedure in craniocerebral surgery. Some patients with traumatic brain injury, cerebral hemorrhage, and cerebral infarction can relieve intracranial hypertension by removing part of the skull, and avoid high intracranial pressure leading to brain herniation and brain tissue necrosis that are life-threatening. There are also some patients who need to resect the damaged skull due to the lesion of the skull itself and cannot repair it at the same time. All of the above patients will have sequelae of skull loss. [0003] After the skull is lost, it is necessary to wait until the patient's condition improves and the skin condition is good before cranioplasty can be performed. Generally, it is necessary to wait until 3-6 months after the craniotomy. During this peri...

[0004] However, the above treatment methods cannot restore the normal physiological shape of the cranial cavity, nor can it restore the normal anatomical position of the tissues in the cranial cavity.

When the long-term compression of the tamponade and the atmospheric pressure directly act on the unsupported soft intracranial tissue, it can lead to the collapse of the intracranial tissue and the ventricular system, which will hinder the circulation of cerebral blood flow and cerebrospinal fluid, which is not conducive to the repair of damaged brain tissue, and even lead to brain swelling And complications such as hydrocephalus, further damage to brain tissue
