Four-cavity balloon supporting device for skull base repair

Abstract

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.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a four-cavity balloon support device for a skull base repair site after transnasal skull base endoscopic surgery. [0002] technical background [0003] 1. Transnasal skull base endoscopic surgery is becoming more and more popular. [0004] In recent years, with the rapid development of endoscopic technology and instruments, the application of skull base endoscopic surgery has become more and more extensive. Compared with microscopes, it has the advantages of clear vision, close observation and optic nerve protection. Therefore, endoscopic technology has been generally favored. From the initial endoscopic transnasal resection of pituitary tumors to the present, craniopharyngiomas and skull base meningiomas can be skillfully resected under transnasal endoscopy. In addition, more and more scholars try endoscopic clipping of aneurysms, resection of chordomas, intracrania...

Problems solved by technology

[0007] 3. At present, there is still a lack of special saddle base support device after skull base repair

At present, there is no special support device for the skull base, and the more common method is to use iodoform or oil gauze to stuff under the skull base through the nasal cavity.

And the disadvantages are obvious: when stuffing, the force on the skull base is required to be uniform, and it needs to be done by a very experienced doctor; the postoperative patient's tolerance is poor, and it is easy to induce malignancy and vomiting, and the patient has difficulty in ventilation and a lot of nasal exudate; when the patient is removed, it is painful Obvious; when pulling out, the closed mucosal flap may be brought out together
