A sterilized nasopharyngoscope with functions of preventing loss and breaking

Abstract

The invention discloses a sterilized nasopharyngoscope with functions of preventing loss and breaking, which belongs to the technical field of medical instruments and comprises a main mirror rod, one end of the main mirror rod is fixedly connected with a first rotating shaft, and the first rotating shaft The surface is sleeved with a first bearing. In the present invention, through the design of the main mirror rod, secondary mirror rod, movable toothed disc, rotating toothed disc, first torsion spring, second torsion spring, first insertion handle, first insertion slot, and second insertion slot , the second insertion handle and the second bearing and other structures cooperate with each other to avoid a lot of time wasted in selecting different types of nasopharyngoscopes, and the elasticity of the second torsion spring can be used to play a certain buffering effect to prevent the entire tool from falling The reaction force received when it falls is relatively large. At the same time, under the effect of the elastic force of the second torsion spring, the stability of the laryngoscope after reset can be guaranteed, and the nasopharyngoscope can be replaced for separate sterilization and disinfection, effectively avoiding cross-infection, etc. The occurrence of adverse phenomena.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a sterilized nasopharyngoscope with functions of preventing loss and breaking. Background technique [0002] Nasopharyngoscope is a medical device for examining the nasopharynx and throat, which can be used for biopsy, surgical treatment of vocal cord nodules or small vocal cord polyps, and removal of foreign bodies in the pharynx. The imaging technology of the microscope can magnify the lesion to thousands of times. The doctor can use the enlarged vocal cord cyst and other lesion tissue to use its own surgical forceps to perform outpatient surgery on vocal cord polyps, vocal cord nodules and other vocal cord lesions. The operation time In short, the patient is basically pain-free. [0003] The nasopharynx is deep and hidden, and it is a frequent site of nasopharyngeal disease. At present, the most commonly used inspection method is to use indirect nasoph...

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve some deficiencies in the process of using the existing nasopharyngoscope, the mirror rod of the nasopharyngoscope is often an integrated structure, and when adjusting the angle of the nasopharyngoscope, it is easy to appear The problem of sliding and slipping leads to a high probability of damage and breakage of the nasopharyngoscope, the main mirror rod and the auxiliary mirror rod, and the angle of the nasopharyngoscope cannot be adjusted or controlled. It is often necessary to prepare a large number of different types of nasopharyngoscopes according to the needs of use. mirror, which not only increases the medical cost, but also the process of finding and replacing a suitable model of nasopharyngoscope is relatively cumbersome. The one-piece structure of nasopharyngoscope will be discarded after being dropped and damaged, and the damaged part cannot be replaced, and it is not convenient for the nose. The pharyngoscope is sterilized separately, which is easy to cause the problem of cross infection, and a sterilized nasopharyngoscope with the function of preventing damage and breaking is proposed
