Description
Technical Field
The invention relates to the technical field of bone fixation and repair, in particular to a unidirectional telescopic skull fixation device which is used for skull fixation and repair.
Background
The fields related to bone fixation and repair comprise neurosurgery, maxillofacial surgery, pectoral surgery, orthopedics and the like, for example, craniotomy of neurosurgery can involve the problem of skull retraction and fixation after operation. The original skull connection mainly depends on silk thread to be fixed, returns and has appeared the fixed mode of skull lock gradually, uses two metal discs promptly to lock the skull from intracranial outsidely, plays the fixed action, but this kind of mode has the risk that epidural hematoma takes place after the operation. Later, the skull is fixed by adopting a bone connection piece fixing mode, namely, a free bone flap and a peripheral bone margin are fixed by using bone nails and bone connection pieces outside the skull, a manual screwdriver is mainly used for fixing at least three connection pieces on the free bone flap by using screws, the skull is accommodated, and then the other end of each connection piece is fixed on the peripheral bone margin by using the manual screwdriver. Over the course of decades, the primary means of using titanium alloy bone attachment tabs and screws to secure them within bone tissue has remained.
Although the traditional fixing mode completely keeps the structures of the bone flap and the skull, the aim of reducing pressure cannot be achieved. The cranial cavity becomes a closed, relatively immobile "vat" as the cranial sutures are substantially closed, usually around the age of 1.5. The large container mainly comprises brain tissue (1400g), cerebrospinal fluid (75ml) and blood (75ml), and under the normal condition, the total volume of the three components and the total volume of the large container keep dynamic balance, so that the intracranial pressure is maintained at a normal level. Because brain tissue volume is relatively constant and cannot be compressed, especially when acute intracranial pressure increases, regulation of intracranial pressure is balanced between cerebral blood volume and cerebrospinal fluid volume. Cerebrospinal fluid is the most variable component, and the amount of cerebrospinal fluid in the ventricles, cisterna cerebri, and subarachnoid space of the cranial spine is about 75ml, accounting for about 5.5% of the cranial cavity volume. When intracranial hypertension occurs, secretion is first reduced by the cerebrospinal fluid, absorption is increased and partial compression out of the cranium relieves the intracranial pressure rise, followed by recompression of cerebral blood volume. Therefore, the compensated volume for relieving intracranial hypertension is about 8% of the cranial cavity volume. Therefore, when the pathological phenomena of cerebral hemorrhage, extensive contusion and laceration of the brain, severe encephaledema, large-area cerebral infarction, diffuse brain swelling, brain tumor and the like are caused, and the volume of the pathological phenomena is increased to exceed the compensated volume of the cranial cavity, the high cranial pressure can be caused. The continuous increase of the intracranial pressure can cause the dysfunction of cerebral blood flow regulation, the cerebral tissue is seriously ischemic and anoxic, cerebral edema is aggravated, the volume of the cerebral tissue is increased, the intracranial pressure is more increased, the cerebral tissue can be displaced to form cerebral hernia, and finally, the cerebral stem is stressed to cause respiratory and circulatory center exhaustion and death.
In clinical work, when a patient with serious intracranial pressure increase performs a bone flap removing and pressure reducing operation, when a patient with mild symptoms (such as unbroken aneurysm) performs a skull fixation operation, the early guarantee of normal intracranial pressure is realized, and the reduction of complications caused by high cranial pressure is the key for improving the prognosis of the patient after the operation. However, for patients suspected of having delayed intracranial pressure increase after intracranial operation, no device can ensure the normal skull to be restored under the premise of stable structure, and the effect of first-stage decompression is achieved. Usually, the problem of removing the bone flap is determined by the operator according to the actual condition of the patient and the condition under observation. Patients with retained bone flap are not rare for patients with decreased prognosis or even secondary surgery due to increased intracranial pressure after surgery. After flap removal and decompression, secondary cranioplasty not only inflicts secondary trauma and increases the risk of infection and anesthesia on the patient, but also places a greater economic burden.
In summary, the conventional skull fixation system can only simply receive and fix the bone flap, and since there is no third option, the surgeon usually ensures the safety of the patient by removing the bone flap, and during the recovery process of the cerebral edema of the patient with the bone flap kept, the brain tissue may be limited by the bone flap to further affect the prognosis.
