A nasal cavity filling air bag device for transnasal neuroendoscopic surgery

Abstract

The invention discloses a nasal cavity filling airbag device for transnasal endoscopic neurosurgery. The nasal cavity filling airbag device includes a nasal cavity tube, an endoscope channel is formedin the nasal cavity tube, and an opening I and an opening II are formed in the two side edges of the endoscope channel correspondingly; the side edge, located on the opening II, of the nasal cavity tube is of a curved edge structure, and a connection ring is installed at the side edge, located at the opening I and away from the opening II, of the nasal cavity tube; an airbag placement cavity is formed in the outer side, away from the endoscope channel, of the nasal cavity tube, and an inflation bag is installed in the airbag placement cavity; and an inflation tube is installed at the side edge, close to the opening I, of the inflation bag, the end, away from the inflation bag, of the inflation tube penetrates through the side wall of the nasal cavity tube and extends below the connectionring, and a connection head I is installed below the connection ring. The nasal cavity filling airbag device has the beneficial effect that the transnasal endoscopic neurosurgery can be better assisted, so that the needs during surgery can be better met.

Description

Technical field [0001] The present invention relates to the technical field of medical appliances, in particular to a nasal cavity filling airbag device used for transnasal neuroendoscopic surgery. Background technique [0002] Currently, transnasal neuroendoscopy is used to treat pituitary tumors, skull base tumors and even aneurysms. The nasal cavity as a neuroendoscopy channel is the necessary channel for this operation. For a long time, due to the rich blood vessels in the nasal cavity, the bleeding and oozing of the channel often lead to the deterioration of the surgical field. It is necessary to repeatedly wash and even continuously remove the endoscopic lens and wipe it; it is extremely easy to repeatedly enter and exit the endoscopic lens. Causes the nasal mucosa to be damaged again, which makes bleeding increase. In clinical practice, some units currently use adrenaline cotton to push and compress the nasal mucosa to create a passage, so that the endoscopic lens can be e...

AI Technical Summary

Problems solved by technology

For a long time, due to the rich blood vessels in the nasal cavity, the bleeding and oozing of this channel often lead to poor surgical field of view, which requires repeated washing or even continuous removal of the endoscopic lens to clean it; Lead to re-injury of the nasal mucosa, resulting in increased bleeding; clinically, some units currently use adrenaline cotton to push and pack the nasal mucosa to create a channel, so that the endoscopic lens can enter and exit conveniently, and the nasal mucosa vasoconstriction achieves the purpose of hemostasis; But the disadvantages are also obvious. Absorption of adrenaline by the nasal mucosa will lead to an increase in blood pressure during the operation, resulting in unpredictable postoperative complications, such as intracranial hemorrhage; some units use nasal dilators, but the nasal dilators cannot effectively compress the middle turbinate and the nasal mucosa of the inferior turbinate, resulting in blood still polluting the surgical field of view along the nasal dilator, and the nasal dilator cannot move after being fixed, which limits the mobility of the endoscopic lens and narrows the surgical field of view, which is not conducive to better surgery Can not better meet the needs of the operation
