Abstract

The invention provides a nasal endoscopic flushing and absorbing drag hook. The nasal endoscopic flushing and absorbing drag hook (100) comprises an endoscopic irrigation cannula (2) which can be fitted over the nasal endoscope and has an interface (1) at a proximal end for connection with the nasal endoscope; And a suction tube, which extends in the same direction as the endoscopic irrigation cannula (2) in such a manner as to cover at least a part of the surface of the endoscopic irrigation cannula (2), the suction tube (3) having a crescent-shaped, circular-like or circular shape in sectionperpendicular to its longitudinal direction, and the distal end of the suction tube (3) protrudes further distally than the distal end of the endoscopic irrigation cannula (2). The nasal endoscopic flushing and absorbing drag hook simultaneously has the functions of exposing the operation field, rinsing the lens and cleaning the hematocele of the operation field, so that the operation can be carried out simultaneously by a single operator, and the operation of exposing the operation field, rinsing the lens or cleaning the hematocele of the operation field and the operation of the nasal part can be carried out at the same time, and the operation becomes more convenient.

Description

technical field [0001] The present invention relates to an auxiliary device used for nose inspection or surgery, in particular to a nasal endoscope flushable suction hook used in conjunction with a nasal endoscope, which simultaneously has the functions of exposing the operating field, flushing the lens and cleaning the operating field Hemorrhage function. Background technique [0002] At present, nasal endoscopy is commonly used when performing inspection or surgery on the nose. Nasal endoscope can easily inspect the internal structure of the nasal cavity, nasopharynx and even the sinus through the narrow nasal cavity and the structure in the nasal passage. It can also perform fine treatment on sinusitis and nasal polyps through the supporting surgical instruments, so that The surgery is able to reach areas that traditional surgery cannot. The common nasal endoscope is a rigid tube scope with angles ranging from 0° to 120°. [0003] In addition, in recent years, more and...
