Movable nasal endoscope integrated suction cannula

Abstract

The movable nasal endoscope integrated suction cannula comprises a nasal endoscope, an endoscope cannula, a fixing buckle, a ball pair, a suction tube and a suction tube cannula; the fixing buckle andthe endoscope cannula are connected into a whole; the nasal endoscope penetrates through the fixing buckle and the endoscope cannula, and the endoscope cannula is fixed to the nasal endoscope throughthe fixing buckle; and the ball pair is arranged on the side face of the endoscope cannula, the endoscope cannula is connected to the suction tube cannula through the ball pair, and the suction tubepenetrates through the suction tube cannula. The ball pair is composed of a ball body and a shell, the shell is fixedly connected to the nasal endoscope cannula, an open spherical hole is formed in the front end of the shell, the ball body is fixedly connected to the suction tube cannula, the ball body is arranged in the shell, the ball body can move in the shell, and the moving range of the suction tube is enlarged. According to the movable nasal endoscope suction cannula, the suction tube and the nasal endoscope are combined together, the combination mobility is high, operation is convenient, and the suction effect is good.

Description

technical field [0001] The invention relates to the field of endoscopic minimally invasive technology, in particular to an integrated suction sleeve of a movable nasal endoscope. Background technique [0002] Nasal endoscope is a kind of otolaryngology equipment. It is an optical device that can carry out detailed inspection of the nasal cavity. It generally refers to a rigid tube mirror with an angle ranging from 0 to 90 degrees. It is relatively thin, with a diameter of only 2.7-4.0mm, but nasal endoscopes are sometimes referred to as flexible endoscopes. Nasal endoscope can easily check the internal structure of nasal cavity, nasopharynx and even sinuses through the narrow nasal cavity and the structure in the nasal passage. It is an important means of diagnosing sinusitis and nasal polyps. Sinusitis Nasal polyps are treated delicately, allowing surgery to reach areas that traditional surgery cannot. [0003] The wide application of nasal endoscopic technology has impro...

Problems solved by technology

[0004] Disadvantages of current nasal endoscopic surgical instruments and improved instruments: 1. Aspirators are installed in the stripper and surgical forceps, which can be used in the case of more bleeding, but the diameter is generally large, resulting in inconvenient operation

2. With a suction flushing system and a power cutting system, it can provide a better surgical field in the case of heavy bleeding and unsatisfactory vision, but if the cutter is used by an inexperienced doctor, it may result in a larger range of tissue cutting , may cause damage to adjacent tissues and organs! 3. Usually, continuous suction and intermittent flushing of the operation cavity are required during the operation to obtain a good view, which requires the operator to hold instruments, such as suction, polyp forceps, etc., with the other hand to operate the endoscopic navigation alone

However, it requires two experienced and cooperative surgeons to operate in a narrow surgical cavity.

It is difficult to perform surgery alone
