Disinfected nasopharyngoscope with damage preventing and fracture preventing functions

Abstract

The invention discloses a disinfected nasopharyngoscope with damage preventing and fracture preventing functions and belongs to the technical field of medical appliances. The disinfected nasopharyngoscope comprises a primary nasopharyngoscope rod, wherein one end of the primary nasopharyngoscope rod is fixedly connected with a first rotating shaft, and a first bearing sleeves the surface of the first rotating shaft. According to the disinfected nasopharyngoscope, through matching of designed structures such as the primary nasopharyngoscope rod, a secondary nasopharyngoscope rod, a movable fluted disc, a rotary fluted disc, a first torsion spring, a second torsion spring, a first socket joint handle, a first socket joint groove, a second socket joint groove, a second socket joint handle anda second bearing, a great lot of time consumed by picking nasopharyngoscopes of different models is avoided; a certain buffering effect can be exerted by using elasticity of the second torsion spring, and thus, the condition that a stressed counteracting force is relatively large when an entire tool falls off is avoided; and meanwhile, under the acting effect of an elastic force of the second torsion spring, the stability of a pharyngoscope after reset can be guaranteed, the nasopharyngoscope can be replaced for independent sterilization and disinfection, and thus, occurrence of adverse phenomena such as cross infection is effectively avoided.

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
