An auxiliary device for nasal endoscopic sinus open drainage

Abstract

The invention discloses a nasal endoscope sinus opening drainage auxiliary device which comprises a shell, a cover arranged on a body and a plurality of fixing mechanisms arranged on the cover. The external contour of the shell is matched with the facial shape around the human nose. An adsorption assembly is arranged at the portion, on the edge of the shell, of the lower surface of the shell. A gap matched with the nose is formed in the middle of the shell. The cover covers the upper portion of the gap. The cover comprises an arc portion and a bearing portion fixedly connected with a connecting portion together, a plurality of through holes are formed in the bearing portion, a plurality of supporting rods and a sleeve body which is arranged on the supporting rods in a sleeving mode and rotationally connected with the supporting rods are arranged on the upper surface of the connecting portion, and each fixing mechanism comprises a fixing clamp which is hinged to the sleeve body and extends to the upper portions of the through holes; the fixing clamps can perform auxiliary fixing on surgical tools such as endoscopes and drainage tubes, the shell is adsorbed to the face through the adsorption assembly, and the device has the advantages of being simple in structure, short in surgical time and high in operability and is suitable for being applied and popularized.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an auxiliary device for nasal endoscopic sinus open drainage. Background technique [0002] Chronic sinusitis tends to occur in adults, and it is also a common and frequently-occurring disease of otolaryngology. Its onset is related to genetic factors, environmental factors and exposure to allergens. When long-term recurrent sinusitis is not treated in time, the inflammatory reaction will spread to adjacent organs and tissues, causing serious consequences. The main clinical manifestations are nasal congestion, nasal discharge, olfactory disturbance or accompanied by headache. Surgical treatment is the main method. In the past, the treatment of this disease was difficult. Its main feature is that the lesion often recurs and is not easy to be completely cured. [0003] In recent years, the incidence of patients with chronic sinusitis and nasal polyps in my country has bee...
