Skull lock

Abstract

The invention discloses a skull lock which comprises a skull lock valve slice, the skull lock valve slice comprises a valve slice main body, the valve slice main body is provided with a plurality of thread holes, a groove and a tooth column, the groove is formed in the mode that the valve slice main body is downwards sunken, the tooth column is formed in the mode that the valve slice main body is upwards protruded, and the tooth column can be fixed to a skull and is prevented from sliding.The skull lock is simple in structure, firm in fixation, controllable in degradation velocity and good in biocompatibility.

Description

technical field [0001] The invention relates to the field of biomaterials, more specifically a skull lock. Background technique [0002] Craniotomy free bone flap forming is a common basic operation in neurosurgery, and it is a necessary step for intracranial operation. Except for some cases of intracranial hypertension that require decompressive craniectomy, in most cases, the free bone flap needs to be reset and fixed after the intracranial operation is completed, so as to restore the integrity of the skull to the maximum extent, maintain the balance and stability of intracranial pressure, and protect brain tissue , to avoid two-stage cranioplasty. When the free bone flap is reset, it needs to be fixed on the surrounding skull with the help of instruments to prevent the bone flap from shifting or pulsating with the brain tissue. [0003] The ideal cranial bone flap fixation material and technique should have the following characteristics: 1) safe in clinical use; 2) good...
