Problems solved by technology

[0003] However, at present, we still perform various operations directly in the nasal passage during the operation, which may cause the nasal mucosa to be damaged due to the repeated entry and exit of instruments during the operation, thereby increasing bleeding during the operation, and the blood is easy to contaminate the endoscopic lens. It affects the light of the endoscope and the clarity of the surgical field, which ultimately affects the operation, cooperation and progress of the operation, increases the surgical trauma, and affects the surgical effect

Abstract

The invention discloses a nasal mucosa protection device used in the intranasal endoscopic basis cranii surgery process, relating to the technical field of medical instruments. The nasal mucosa protection device comprises a trumpet-shaped body and a front-end limiting body, wherein the front-end limiting body is arranged at the front end of the trumpet-shaped body, the front end of the trumpet-shaped body is narrower than the tail end of the trumpet-shaped body, and the trumpet-shaped body is made of plastic with a self-expansion telescopic function. The nasal mucosa protection device has the advantages that the structural design is reasonable, the use is convenient and reliable, the nasal mucosa can be protected, and the nasal mucosa can be protected from being injured during the operation.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a nasal mucosa protection device used in transnasal endoscopic skull base surgery. Background technique [0002] Transnasal endoscopic surgery is the use of high-resolution, variable viewing angle endoscopes to perform operations on sinus and skull base lesions, so that operations on nasal cavity, sinuses, and especially deep skull base lesions can be performed under direct vision. The skull base is located between the skull and the facial features. This area involves neurosurgery, ophthalmology, otolaryngology-head and neck surgery, oral and maxillofacial surgery and other disciplines, and belongs to an interdisciplinary specialty. The anatomical location of this area is deep, the anatomical relationship is complex, and there are many important nerves and blood vessels passing through the area. The operation requires the assistance and participation of various new tec...
