Irrigation device for nasal endoscope

Technical Field

The utility model relates to the field of ear-nose-throat medical instruments, in particular to a flushing device for a nasal endoscope.

Background

The nasal endoscope, i.e., the nasal endoscope, is a minimally invasive medical examination/surgical instrument with good illumination, which allows for finer surgery and access to areas not accessible by conventional surgery through the use of a companion surgical instrument. Specifically, the nasal endoscope can conveniently check the internal structures of the nasal cavity, the nasopharynx part and even the paranasal sinuses through the structures in the narrow nasal cavity and the nasal passages, is an important means for diagnosing nasal polyps of nasosinusitis, can finely treat the nasal polyps of nasosinusitis through matched surgical instruments, and enables the surgery to reach the area which cannot be reached by the traditional surgery.

The structure of the currently commonly used intranasal endoscope is shown in fig. 1, the total length of the endoscope body is about 20cm, the structure comprises an endoscope body extending section a positioned at the front section and an endoscope body handheld operation section b positioned at the rear section, wherein the length of the endoscope body extending section a is about 10cm, the section enters and exits the nasal cavity during examination or operation, and the rear endoscope body handheld operation section b is held by an operator.

In the use process of the current nasal endoscope, the nasal cavity is often required to be filled with water for nasal cavity cleaning. When washing, generally a doctor uses the nose scope, and a nurse uses the syringe to the water injection in the nasal cavity, this just needs two at least people to accomplish the operation in the narrow and small space on the operation station that just leads to, can't accomplish nasal cavity inspection and nasal cavity cleaning process by doctor alone, not only operates inconveniently, has improved the human cost moreover.

In order to solve the above problems, a person skilled in the art makes many improvements, such as chinese patent CN202021058413.2, patent name "nasal endoscope with irrigator function", and the disclosed irrigation device, though it can implement single nasal endoscope and irrigation operation by structural improvement, its water supply pipeline is connected with the endoscope body only through one buckle, the connection is not reliable and easy to fall off, and the connection part is located at the part entering the nasal cavity, which can affect the visual field of the operator, in addition, the patent needs to additionally add a pressure type water outlet device and a water supply unit such as a barrel-shaped container, the equipment investment is more, the cost is high and the occupied area is large, in addition, the irrigation device needs to use foot treading to control irrigation pressure, the pressure is too large and is easy to cause tissue generated in operation, blood enters into the eustachian tube, enters into the middle ear cavity, and causes otitis; in addition, the pipeline and the endoscope of the device are integrated, the cleaning of the endoscope body is more complex, a sterile water storage container is needed, and sterile liquid is injected into the sterile water storage container, so that the device is easy to pollute. For example, chinese patent CN202123270104.9, entitled "nasal endoscope with irrigator function", which integrates an endoscope and an irrigator, thus increasing the overall diameter of the endoscope, so that the field of view of the mirror surface of the scope is reduced.
