The invention belongs to the field of
medical instruments, and particularly relates to a four-cavity
balloon supporting device for a
skull base repairing part after a transnasal
skull base
endoscopic surgery. The device comprises four independent telescopic air bags and inflation pipelines connected with the telescopic air bags, wherein the air bags comprise a supporting
balloon, two fixation balloons and a compression
balloon in sequence from the far end to the near end; under the direct view of an
endoscope, 5-10 ml of gas is injected into the respective inflation pipelines through an
injector, so that the corresponding balloons are expanded; and the specific situation is determined according to the filling degree of the balloons observed under the
endoscope. The surface of each balloon is coated with nano-loaded
antibiotics and an anti-adhesion material; and the
tail end of each air passage is provided with a one-way valve, and when the device needs to be pulled out after an operation, the device can be pulled out simply by opening the valves through the
injector and releasing gas in the corresponding balloon. The device has dual functions of
skull base supporting and compression
hemostasis, and an operator can fill one or more combined balloons according to own requirements and the gasification state of the
nasal cavity and the paranasal sinus of a patient. The four-cavity balloon supporting device can effectively reduce the occurrence of postoperative
cerebrospinal fluid leakage,
intracranial infection and other complications.
