Nasal sinus ball pouch expansion suction tube

Abstract

The invention discloses a device for expanding natural aditus antrum of nasal sinus in nasal sinus operation, which belongs to the field of medicinal appliance and particularly relates to a catheter having expanding and sucking functions for nasal sinus surgical operation. The catheter is made of hard silica gel material and is an expansion and suction catheter which comprises an air bag, an inflating tube and a suction tube and is applicable to nasal sinus operation in many aspects, wherein the inflating tube is attached on the side wall of the suction tube, and the air bag with scale marks is positioned on the head side of the catheter. An operation handle is arranged on the tail side of the catheter. The catheter can be positioned under a nasal endoscopic and directly inserted into the natural aditus antrum of nasal sinus. The structure of the catheter is simple and the operation of the catheter is convenient. The catheter can accurately expand the aditus antrum of nasal sinus and lays a foundation for the implementation of the operation.

Description

technical field [0001] The utility model relates to a device for expanding the natural sinus ostium of a nasal sinus, which belongs to the field of medical equipment, in particular to a catheter integrating expansion and suction functions in sinus surgery. Background technique [0002] With the aggravation of air pollution, the number of patients with nasal cavity diseases such as sinusitis increases year by year, and recurrent attacks have brought a lot of inconvenience to the normal life of the people. According to a survey in the United States: more than 37 million Americans suffer from different degrees of sinusitis every year, and the number of cases is increasing year by year. There is no similar data in China, but it is estimated that the number of patients with sinusitis will exceed 50 million per year. For patients with unsatisfactory drug treatment, the most commonly used and most effective treatment is "functional" endoscopic sinus opening, which aims to reconstr...

Problems solved by technology

[0004] In order to overcome the shortcomings of the existing sinus balloon dilatation that must be performed under the guidance of a guide wire, the operator has to accept X-ray radiation or use additional optical fibers and have a single function, the inventor combined his own clinical experience and invented a sinus balloon dilation Suction tube, specifically: a balloon is placed at the front end of the hard suction tube at different angles, the inflation tube of the balloon is fixed on the outer wall of the suction tube, and the tail end is separated from the suction tube. The tail end of the suction tube and the tail end of the inflation tube are respectively With respective connectors for connection to inflator and suction
