Otolaryngology department expansion device capable of conveniently expanding and supporting an auditory meatus

Abstract

The invention discloses an otolaryngology department expansion device capable of conveniently expanding and supporting an auditory meatus, which comprises a driving rod, the outer side of the upper end of the driving rod is fixedly connected with a control turntable, and the lower end of the driving rod is provided with symmetrical threads; side lifting lugs are fixedly connected to the two sides of an expansion plate, bearing lifting lugs are symmetrically and fixedly connected to the outer side of a limiting connecting ring, spring covers are fixedly connected to the inner sides, opposite to the bearing lifting lugs, of the side lifting lugs, and buffering devices are arranged in the spring covers, so that when an expansion mechanism starts, buffering springs in a buffering mechanism can be lengthened or shortened, the expansion stress can be effectively reduced, and the expansion mechanism is prevented from injuring the ear canal, and one sides of the side lifting lugs and one side of the bearing lifting lugs are fixedly connected with a rod sleeve and a round rod, and when the expansion mechanism drives the expansion plate to return to the original position, the rod sleeve can be sleeved into the round rod, so that the round rod can be used for limiting, excessive contraction is prevented, and the protection effect can be achieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an expansion device for otolaryngology which is convenient for expanding and supporting the ear canal. Background technique [0002] Otolaryngology includes the ear, nose, throat and other parts, which are some parts of the human body that are more prone to disease, and are also the diseases that most easily trouble and affect people's normal work and life. When medical staff check the patient's ear canal, for the convenience of Observe the condition of the ear canal, usually need to expand the ear canal support. [0003] However, in the current expansion of the ear canal, most of them use tweezers to open the patient's ear, and then the doctor performs the operation, which causes the tweezers to easily injure the patient's ear canal, and it is not convenient to fix the expanded size, so There is a need for an otolaryngology dilating device that is convenient...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide an otolaryngology dilatation device that is convenient for dilating and supporting the ear canal, so as to solve the problem that most of the above-mentioned background technologies use tweezers to spread the patient's ear , and then operated by the doctor, which leads to the problem that the tweezers are easy to injure the patient's ear canal, and it is not convenient to fix the expanded size
