Device for mending skull base defects

Abstract

The invention belongs to the medical equipment field and especially relates to a device for mending skull base defects. An existing mended skull base defect device is easy to cause damages to blood vessels or other brain tissues in a cranial body during usage, and operation time is long and usage is not convenient. Aiming at the above problems, a solution scheme is characterized in that a first fixation plate located in the cranial body around a defective cavity to be mended is included; one side wall of the first fixation plate, which is close to the inner wall of the cranial body, is provided with a placing groove; the middle position of the bottom end side wall of the placing groove is provided with a threaded rod; one end of the threaded rod is extended to the external portion of the cranial body; folding plates which are folded in the placing groove when not in use are hinged to the side walls of the placing groove; one end of each folding plate, which is far away from a hinged position, is provided with a chute; and a limiting plate is slidably connected into the chute. In the invention, the defective position of a skull base can be conveniently and rapidly mended, sealing performance is good, the risk of the damage to the blood vessels or other brain tissues in the cranial body is reduced, and operation time is short.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a device for repairing skull base defects. Background technique [0002] With the development of neurosurgical equipment and technology, a large number of skull base operations can be carried out, but minimally invasive surgery at the expense of skull base bone, due to the deep surgical site and narrow operating space, large skull base surgery often occurs after surgery. Defects of bone, dura mater, and local soft tissue in the operative field increase the possibility of postoperative complications such as cerebrospinal fluid leakage, meningitis, pneumocranium, and encephalocele. Cerebrospinal fluid leakage is the most common complication after extended transsphenoidal surgery. Cerebrospinal fluid leakage is a common complication after skull base surgery, especially extended transsphenoidal surgery. In order to prevent cerebrospinal fluid leakage and reduce complication...
