Bendable sinoscope

Abstract

The invention discloses a bendable sinoscope which comprises a handle body and a sinoscope rod assembly mounted at the front end of the handle body. The sinoscope rod assembly comprises a sinoscope sheath and a flexible supporting column sleeved with the sinoscope sheath in a coaxial running fit mode. An observation system is arranged in the flexible supporting column, and an observation window of the observation system is fixedly arranged on the front end face of the flexible supporting column. An outer pipe is controlled to axially move, so that the outer pipe drives an inner pipe to be bent on an elastic segment, and the sinoscope can be inserted conveniently after being bent. At the same time, the front end face of the flexible supporting column can be an inclined face inclined relative to the center axis. The front end face of the flexible supporting column is arranged to be the inclined face, the flexible supporting column can be driven by external force to rotate around the center axis of itself, and the visual range is widened. The whole sinoscope is simple in structure, convenient to operate, good in stability, low in cost and easy to popularize. Pus can be directly sucked through an arranged suction channel and can be completely sucked, operative wounds caused by invasive operation cleaning can be avoided, and pain of a patient can be relieved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a bendable sinus mirror. Background technique [0002] An endoscope is a tube equipped with light, which can enter the human body through the natural orifice of the human body or a small incision made by surgery. After being illuminated by the light guide tube, the image is collected for analysis, which is convenient for doctors to diagnose and treat; while in sinus surgery , especially for maxillary sinus surgery, due to the limited observation range of the usual rigid endoscope, it cannot pass through the natural sinus ostium of the maxillary sinus, so that the maxillary sinus surgery often requires an additional opening, but increases the surgical trauma, which is not conducive to the patient's recovery; In view of the above problems, although there are some products that can be fully endoscoped in the prior art, their structures are more complicated, their stability is poor...

[0002] An endoscope is a tube equipped with light, which can enter the human body through the natural orifice of the human body or a small incision made by surgery. After being illuminated by the light guide tube, the image is collected for analysis, which is convenient for doctors to diagnose and treat; while in sinus surgery , especially for maxillary sinus surgery, due to the limited observation range of the usual rigid endoscope, it cannot pass through the natural sinus ostium of the maxillary sinus, so that the maxillary sinus surgery often requires an additional opening, but increases the surgical trauma, which is not conducive to the patient's recovery; In view of the above problems, although there are some products that can be fully endoscoped in the prior art, their structures are relatively complicated, their stability is poor, and the direction of the lens cannot be adjusted, causing their applications to be limited.
