One-way retractable skull fixation device

Abstract

The invention discloses a unidirectional telescopic skull fixation device, which belongs to the technical field of bone fixation and repair. The fixation device includes a bone flap side fixation structure, a skull side fixation structure and sliding rods, and the bone flap side fixation structure is connected with the skull side fixation structure by the sliding rods. The fixation device providesa new means and method for return and fixation of a bone flap after a craniocerebral operation, a new option is added between pure complete fixation and removal of the bone flap, the fixation deviceis used for patients who may have increased intracranial pressure after surgery, the problem of the increased intracranial pressure after pure skull fixation can be effectively solved, the fixation device can help to control the risk of postoperative brain tissue swelling of the patients, and at the same time, the strength of the device is stronger than that of a traditional nail plate fixation system and a skull locking system, and the stability of the bone flap after the return is ensured.

Description

technical field [0001] The invention relates to the technical field of bone fixation and repair, in particular to a one-way retractable skull fixation device, which is used for skull fixation and repair. Background technique [0002] The fields involving bone fixation and repair include neurosurgery, maxillofacial surgery, thoracic and cardiothoracic surgery, orthopedics, etc. For example, neurosurgery craniotomy involves postoperative skull restoration and fixation. In the past, the cranial connection was mainly fixed by silk thread. Later, the cranial lock fixation method gradually appeared, that is, two metal discs were used to lock the skull from inside and outside the cranium to play a role of fixation. However, this method may cause epidural hematoma after surgery. risks of. Later, the skull was fixed with bone connectors, that is, the free bone flap and the surrounding bone margins were fixed with bone nails and bone connectors on the outside of the skull. After the...

AI Technical Summary

Problems solved by technology

[0005] To sum up, the traditional cranial fixation system can only simply return and fix the bone flap. Since there is no third option, the surgeon often removes the bone flap to ensure the safety of the patient. Cerebral edema in patients who retain the bone flap During recovery, the brain tissue may be restricted by the bone flap and affect the prognosis
