Trans-nasal nerve skull base repair device, skull base repair membrane and using method of transnasal nerve skull base repair device

Abstract

The invention relates to a transnasal nerve skull base repair device, a skull base repair membrane and a using method of the device. The transnasal nerve skull base repair device comprises a first repair membrane assembly used for repairing a liliequist membrane ventage and a second repair membrane assembly used for repairing a dura mater ventage. According to the transnasal nerve skull base repairing device, the skull base repairing membrane and the using method of the device, through cooperative use of the fusible biological membrane, the non-fusible biological membrane, the supporting piece, the hemostatic yarn and the fixing air bag, the technical scheme is compact in structure, high in clinical practicability and remarkable in effect; the skull base repair is successfully realized, the occurrence of postoperative complication cerebrospinal fluid leakage of the transnasal neuroendoscopy is prevented, the risk of intracranial infection is reduced, the possibility of endangering the life of a patient is reduced, the life quality of the patient is improved, and the prognosis is improved; in addition, artificial materials are adopted in the repairing process of the method.

Description

technical field [0001] The invention relates to the technical field of skull base repair, in particular to a transnasal nerve skull base repair device, a skull base repair membrane and a method for using the device. Background technique [0002] Transnasal neuroendoscopic surgery has the advantages of wide operating angle, high illumination intensity, strong direct vision, and small trauma, so it is widely used in space-occupying lesions in the intracranial sellar region (such as pituitary adenoma, craniopharyngioma, Rathke cyst, etc.) , meningioma, etc.) resection and treatment. Usually, the skull base bone, dura mater, and liliequist membrane will be damaged to varying degrees during transnasal neuroendoscopic surgery, which increases the occurrence of postoperative cerebrospinal fluid leakage; therefore, postoperative transnasal neuroendoscopic skull base Restoration has important practical value in preventing the occurrence of cerebrospinal fluid leakage.
