Description

Skull-missing protective exoskeleton patch

Technical Field

The invention relates to the technical field of medical instruments, in particular to a skull-missing protective exoskeleton patch.

Background

Craniectomy is a common surgical procedure used in craniocerebral surgery. Partial craniocerebral trauma, cerebral hemorrhage and cerebral infarction patients can relieve intracranial hypertension by cutting off partial cranium, and avoid the life threatening caused by cerebral hernia and brain tissue necrosis due to the intracranial hypertension. Some patients need to remove the damaged skull due to the pathological changes of the skull and cannot repair the damaged skull at the same time. The patients can leave behind the sequelae of skull deletion.

The skull can be repaired only when the patient has better disease and the skin has good condition after the skull is lost, and the skull is lost as a hazard when the patient generally needs to wait for 3-6 months after the craniectomy. Without skull protection, intracranial tissues can be easily injured by external force. After the integrity of cranial cavity is destroyed, when the position of a patient changes, coughs and sneezes repeatedly, the pressure of cranial cavity fluctuates sharply, so that intracranial tissues swell and collapse repeatedly, and the tissues are shifted and pulled to cause the harm of intracranial hemorrhage, encephalic tissue incarceration and the like. Aiming at the risks, the family members need to strengthen the monitoring of the patient with the skull loss to avoid the trauma. Clinically, soft materials such as cotton and gauze are often filled in the bone window, and bandaged to maintain stable intracranial pressure, or a protective plate is further covered outside the bone window or a protective cap is worn to avoid external force damage.

However, the above treatment methods do not restore the normal physiological morphology of the cranial cavity, nor the normal anatomical position of the tissue within the cranial cavity. When the tamponade is pressed for a long time and the atmospheric pressure directly acts on unsupported soft intracranial tissues, the intracranial tissues and a cerebral ventricular system can be caused to collapse, cerebral blood flow disorder and cerebrospinal fluid circulation disorder are caused, the repair of damaged cerebral tissues is not facilitated, even complications such as cerebral swelling, hydrocephalus and the like are caused, and the cerebral tissues are further damaged. The formation of brain swelling and hydrocephalus is not beneficial to the follow-up skull repair operation, and partial patients even need to be compensated by ventricular shunt. When a patient is in a skull-missing state for a long time and carries out skull repair operation, under the condition of suddenly recovering the normal form of a cranial cavity, the suddenly changed anatomical position of intracranial tissues and intracranial pressure can influence the cerebral blood supply and the cerebrospinal fluid circulation, and complications such as intracranial hemorrhage, epilepsy, hydrocephalus and the like can be caused.

Therefore, aiming at a patient with cranialescectomy, the cranialescectomy device not only needs to resist external force to directly damage intracranial tissues and maintain normal and stable intracranial pressure, but also needs to recover the normal physiological form of the cranial cavity as early as possible, recover the normal anatomical position of the tissues in the cranial cavity and avoid the collapse of the intracranial tissues and a ventricular system, thereby being beneficial to improving the blood supply of the cerebral tissues, reducing the probability of the occurrence of complications such as intracranial hemorrhage, epilepsy, hydrocephalus and the like, creating favorable conditions for the subsequent cranioplasty and enabling the patient to obtain better prognosis.
