Description

Technical Field

[0001] This invention relates to the field of cranial bone flap fixation technology, specifically to a cranial bone flap fixation device. Background Technology

[0002] Cranioplasty is a common neurosurgical procedure that addresses abnormal cerebral blood supply, insufficient or obstructed cerebrospinal fluid circulation, and brain compression caused by skull defects. It repairs the defect area, compensates for mechanical safety issues of brain tissue, and resolves abnormal problems such as insufficient or obstructed cerebral blood supply and cerebrospinal fluid circulation. It also needs to consider the restoration and reshaping of the original shape. The cranial bone flap fixation device is a medical device used to fix bone flaps after craniotomy. In neurosurgery and other surgeries, it is usually necessary to open the skull to perform necessary surgical operations.

[0003] For example, the Chinese authorized patent CN215503334U (A device for fixing cranial bone flaps) includes a first support frame, suction cups, a loading box, a cover plate, a magnet, a guide rail, a first slider, a placement plate, a first spring, a second support frame, and a disc. The first support frame has four suction cups evenly spaced on it, and a loading box is located on one side of the first support frame. The beneficial effect of this invention is that by pushing the clamps outwards and placing the cranial bone flap between them, the placement plate and the first slider slide downwards, thus facilitating the fixation of the cranial bone flap. This eliminates the need for welding or adhesive bonding to tightly fix the device, providing greater convenience for cranial bone flap fixation.

[0004] However, most existing cranial bone flap fixation methods use compression from different directions, which can easily cause compression damage to the edges of the cranial bone flap and cause friction damage during handling. Therefore, these methods do not meet current needs. To address this, we propose a cranial bone flap fixation device. Summary of the Invention
